How to identify the installation quality of the PV system?

First,check whether the photovoltaic components are blocked

The components between a PV array are linked in series, and component occlusion affects the amount of power generated by the entire array. For example, if a PV array is 6 components, if part of one of the components is shaded due to occlusion, the power generation of the six components will be affected. In addition, occlusion can cause hot spots on the components, resulting in damage to the components.c profile steel suppliers

Second,check the connection cable routing

To install a distributed PV system, you need to connect cables. For high-quality construction, the wiring must be neat and regular. In addition, the cable will be installed outside the cable, which is both beautiful and protects the cable. The route is a standard for inspection and construction, but it is not a hard indicator. The route will basically not affect the power generation, but it can test the strength of the construction party. A quality construction team must pay attention to every detail.

Third,check whether the product has a warranty and a certificate of conformity

Qualified products are a prerequisite for ensuring the power generation of photovoltaic systems. The products of regular manufacturers have the factory certificate of conformity and the quality assurance documents. In addition, whether the component has a serial number or whether the inverter has a nameplate is also a message to check whether the product is from a regular manufacturer. Matters needing attention: Finally, final inspection is required according to the construction drawings z profile steel. If there is any problem, it is necessary to communicate with the construction party and the material staff in time; if there is any problem with the above, it is necessary to communicate with the construction party and the material staff in time.

Fourth,view the installation tilt of the component

The mounting angle of the component is a very complicated problem, and it is impossible to judge by the naked eye whether the inclination of the component is the optimum inclination. However, if the PV system’s component tilt angle is too large, then be careful, the wind resistance of this system will be worrying.

The Federal Hawking School is preparing to cut the functionality of the new solar installation, which will offset 70% of the school’s annual energy use of renewable energy. Students will “flip the switch” on the 700 kW solar system for the first time on July 11th at the Federal Hawking High School campus. Federal Hawking administrator George Wood will speak at the event.Steel Profile suppliers

“Solar and renewable energy are the future direction,” George Wood said. “However, from here to there will be large organizations and institutions, such as major school actions. Our region is a demonstration that other regions can do.”

Participants will be joined by former governor and clean energy advocate Ted Strickland and other local politicians. The incident occurred after the recent appointment of Michel Sun Greenfield, CEO of Third Sun Solar, to implement the Workforce Development Committee for the Governor.

The array was built and installed by a team of installers, Third Sun Solar. New resource solutions,z profile building financing and foundation renewable energy companies; and system owners and operators.

“Third Solar installed solar energy in more than 70 schools, but the project is very exciting because it is in our community,” said Jeff Greenfield, president and co-founder. “Although it is very attractive to the economic interests of the school, we believe that the benefits of our local economy, such as the increasing amount of solar work, are also very important.”

Several installers for the project are students at Federal-Hocking High School and Union Vocational School.

Profile steel is a strip steel with a certain cross-sectional shape and size. It is one of the four major steel products (plate, tube, type, wire). According to the shape of the section, the section steel is divided into a simple section steel and a complex section steel (shaped steel). The former refers to square steel, round steel, flat steel, angle steel, hexagonal steel, etc.; the latter refers to I-beam, omega profile,channel steel, steel rail, window frame steel, curved steel and so on.

Several major categories of steel:

According to the quality of steel smelting, steel is divided into ordinary steel and high quality steel. Ordinary steel is divided into large section steel, medium section steel and small section steel according to the current metal product catalogue. Ordinary steel can be divided into I-beam, channel steel, angle steel, round steel, etc. according to its sectional shape.

Large-sized steel: large-sized steel I-beam, channel steel, angle steel, flat steel are hot-rolled, round steel, square steel, hexagonal steel in addition to hot rolling, there are forging, cold drawing and so on.

I-beams, channel steels and angle steels are widely used in industrial buildings and metal structures, such as factories, bridges, ships, agricultural machinery and vehicle manufacturing, transmission towers, and transportation machinery. Flat steel is used as a bridge, a frame, a fence, a power transmission ship, a vehicle, etc. in a construction site. Round steel and square steel are used as various mechanical parts, agricultural machinery parts and tools.

Medium-sized steel: medium-sized steel medium, groove, angle, round, flat steel, the use is similar to large steel.

Small section steel: small section steel medium angle, round, square, flat steel, processing and use similar to large steel, small diameter round steel is often used as building reinforcement.

Many individuals aren’t truly conscious of the truth that you can minimize things with a laser. It’s understood that manufacturing of 800 thousand square meters of “Color seismic activity board room”, the required colour steel reached 14 thousand to fifteen thousand tons. The classic and conventional look of wood garage doorways is unmatched. Even in a narrow vary of concentrations of mixtures of carbon and iron that make a steel, numerous different metallurgical structures, with very different properties can kind.

A silvery-white, ductile metallic element used in making dental alloys and forming compounds with pharmaceutical uses, particularly as astringents and antiseptics. Mild Metal is basically Steel which is a composition of Iron and Carbon.

Aluminium alloys casting and merchandise manufactured by them are issues of the longer term as a result of their cost effectiveness and light-weight.

Wooden storage doorways might be easily painted or stained within the colour of your selection. If one involves the choice of storage door now the question arises both he should buy a steel door or a door manufactured from aluminum will show higher for his house. Many steel undergo an embossing course of so that they resemble wooden. 9 The above assumes that the cooling course of is very slow, permitting enough time for the carbon to migrate.

Smelting, using carbon to scale back iron oxides, ends in an alloy ( pig iron ) that retains too much carbon to be called steel. There are various advantages of utilizing the steel laser reducing over mechanical slicing processes. eight When carbon strikes out of resolution with iron, it types a very hard, however brittle material referred to as cementite (Fe3C). 3.Power Business: Because of the low density of aluminum, this metallic is the first selection to be used in energy industries.

From flat irons, curling irons and hair setters and rollers to beauty care cosmetics, Flat Iron Specialists has in its product line to boost your total beauty. In my analysis on the query, what is brazing, I studied one of the best methods for brazing chrome steel and different metals.

Children’s dollhouses for the duration of the 20th century have been created from a range of supplies, like metal ( tin litho ), fibreboard, plastic, and wood. In most of the globe, Christmas gifts are given at evening on Christmas Eve, or in the morning on Christmas Day. By contrast, the original dolls confronted some of the most heated issues of their respective occasions. Over the years that museum has received thousands of letters from folks who’ve had anything occur soon after they disrespected Robert and I am positive a lot of them are entirely explainable. She was originally marketed as a “Teenage Style Model” and around 350,000 dolls have been sold in the course of the initial year. When the company launched, eager girls could only order from just 3 dolls in the catalogs — Kirsten Larson, Samantha Parkington, and Molly McIntyre.
Barbie’s look has been changed several occasions, most notably in 1971 when the doll’s eyes were adjusted to appear forwards rather than getting the demure sideways glance of the original model. The curse of Robert The Doll grew into such a well-recognized legend in Key West that whenever issues went wrong, locals would simply shrug and say, Blame it on Robert.” But Robert’s real fame came when the Chucky” horror film series (Child’s Play, Child’s Play two, Child’s Play 3, Bride of Chucky, Seed of Chucky, etc.) came out, as they have been said to have been modeled on the genuine-life story of Robert the Doll.

Fake apple, replica of Lee brand Jeans, counterfeit brand, we could easily know these three words, and three synonyms as Fake, Replicas and Counterfeit being contained in these three words. Someone will say “this is too easy, we apply these words during our daily life, there is nothing to be distinguished because of same meaning.” well, perhaps this theory is correct when we just read. Only if you think about it more, and you may find some difference among these synonyms as fake, replicas and counterfeit. So what is the difference among three words? Let us analyze slowly and detailed.

Counterfeit VS. Fake

I have discussed with my friend, a teacher for English. So I think these explanation below with enough and complete persuasion. Certainly, you may also refer to related reading material and dictionary online for more detail.

All counterfeits are fakes, but not all fakes are counterfeits. As tdol, a blogger says, ‘counterfeit’ means you are trying to deceive someone, while ‘fake’ just means it’s not the real thing, and doesn’t imply anything about any intention.So counterfeit money is fake money which is also intended to look so much like the real thing, that people can actually use it to buy things.

It’s also possible to have fake money that is not counterfeit. Such a thing is used, for example, in the film business. Although the fake money looks on screen like the real thing, it is not intended to be used to buy things in real life and would be recognized as a fake by anyone who looked at it.

Replica VS. Fake

Replicas and fakes are the same things that are not as original or authentic, but these phrases are used in various contexts. A word replica is essentially utilized to signify that a item that isn’t genuine but is used for a few particular reasons whereas a Fake isn’t merely a product. It’s used in a lot of contexts.

Replicas are duplicates or imitation of authentic products. These goods can be varied, which range from branded things such as, clothing, jewelry, shoes, leather goods, accessories, as well as trophy awarded for sports, etc.. Occasionally the replicas also are utilized in museums and additional sports or award functions since the authentic things are too pricey to be transferred from one site to the other and also the hassles involved to organize for their safety. The major thing about a replica is that they might be quite a close copy and nearly indistinguishable from the authentic or original. Replicas can also be used occasionally when the first thing never existed and it needs to be exhibited in a museum.

There is the example for replica, but it is also the real things as reference for every readers. You may be able to know the define of replica, there are a lot of replica products in China now. No matter what products referring to brand clothes, jewelry and so on, in China the small manufacturers and many private workshops could copy it and produce almost same things but not authentic by brand company,

then they sale the products and commodities to everywhere, not only in China, actually now it is in the USA, or other oversea markets. Brand and retailers still being hurt by replicas products from China. You may read more detail through New USTR.

Well, after we explained about word replicas, then it is time for Fake. As above mentioned distinguished between counterfeit and fake, I think all of you have understood the difference between these two words, but below context about explanation of fake will give you more understand or saying comprehension about word, fake.

Fake goods are duplicates of original products and also therefore are utilized to earn money by selling the low cost and cheaper version for a rather expensive price. The majority of the time, people purchasing fakes will not intent to buy a fake, just as cheap by seller for purchasing a fake.

“Fake” is used to refer to many different items which range from movie collections, to props used in dramas, dance or theatre. The roles of fiction and science stories are well-known as not real characters or saying fake characters. Fictitious examples employed for medication or legislation functions are known as a fake. The behaviour of someone who isn’t behaving like himself is known as untrue behaviour, so called fake behavior.

Fakes may be easily available. They’re more economical due to inferior quality and therefore are at a probability of less harm since they don’t need animals to be murdered as in the case of fake fur and ivory, etc.. In addition, they don’t need licenses as for a lot of guns. Generally language, word as fake and replica are used interchangeably. However, word as replica is used more frequently as a legitimate backup than a fake is considered.

Now I trust that all people have read my post will understand and grasp what difference among these three words Fake, replica and counterfeit. Maybe someone do not care these different meaning because the most of time these words will not give us some bad effect or lousy experience when we use them. But I still believe that correctly using some words, exactly synonym words ensure to help us to communicate with others better. From another angle to analyze, we may know more knowledge about Language, English. Certainly, please expecting my next share of difference among some synonym words, if you are in free, please visit to my blog and read more. I also expect that we may interact for these topic articles.

We provide full range picks of Galvanized Iron (GI) Pipes & Fittings in Malaysia. Moreover, if your galvanized pipes had been ever related to steer plumbing (including service strains) there’s more cause for concern. Additionally it is typically referred to as galvanized iron pipe. This zinc coating helps forestall rust. Galvanized pipes are still generally found in residences, together with multi-family communities, all throughout the United States. In chilly home water methods, galvanized metal could be very in style and is used as much or greater than copper, notably in larger sizes, as a result of its decrease material costs. Nevertheless, because it turns out, galvanized pipes develop every kind of issues over time and are actually commonly changed with copper piping. As for water line use, I have no idea of any plumber that may use any type of steel pipe for water, when pex, pvc, cpvc or copper is best. Galvanized or lead water pipes had been put in in Minneapolis properties solely up till 1928, and in Saint Paul homes up till 1925. But if the rust is intensive, underground, or inside the pipe, you want the service of a plumbing skilled. Within the technique of forming a new recipe and adding the correct amount of iron, in order that the unique single-plated zinc alloy metallic plating layer is shaped. PEX is a pipe that is inflexible enough to withstand the pressures of water provide but flexible enough to weave throughout walls, ceilings, basements, and crawlspaces. Instead of having to replace pipes and fittings usually, attempt to enhance the longevity of your merchandise through the use of galvanized steel pipe in your next mission. Pipe ordered beneath these specifications is nominal(average) wall and is intended for peculiar makes use of in steam, water, gasoline and air traces, but is just not supposed for close coiling or bending, or high-temperature service. This is a look at among the issues associated with galvanized steel pipes, and what you are able to do about them. Whereas galvanized pipes are inherently good and have many benefits, the drawbacks are additionally cringe-worthy. It will rust earlier than the steel beneath it, protecting the integrity of the pipe intact for for much longer than common pipes. three, threaded course of connection strain test of the complete system installed, or use, pipeline leak occurred after maintenance harder. As such, galvanized pipe is just used in trendy homes for hand rails and substitute of present pipe. Here is easy methods to decide in case your pipes are galvanized. After hot-rolled seamless metal tube spherical baked to undergo the stress puncher piercing. Using galvanized pipe for water service is a really poor selection of supplies. In the case of galvanized pipe so ordered, the bottom steel shall be made and tested in accordance with the Specs A53 and the pipe shall be galvanized and the coating tested in accordance with these specs A120. Our galvanised steel pipe is the best resolution to create underpasses for autos, pedestrians, livestock and waterways. In addition, rust-choked galvanized metal pipes are unable to deliver the needed quantity of water to residents. HEL-COR helically corrugated metallic pipe gives the power to withstand extreme environmental conditions and burial depths related to culverts, storm sewers, and stormwater detention systems. It has a lifespan of 40-50 years and since it hasn’t been installed for longer than that, you possibly can assume that any galvanized pipes you discover have exceeded their lifespan. Copper pipes are also extra inclined to face up to earthquakes. In the event you see a thicker pipe coming up out of the basement ground with threads on the tip, it is most likely a galvanized supply pipe.

The new pipe restores the circulation of the pipe to most pressure and prevents further spread of corrosion or leaching of lead into the potable water. Although the rust itself isn’t normally dangerous, it could alter the taste and look of water and trigger discoloration of plumbing fixtures and even clothing. The principle advantage of using galvanized fittings is their superior rust resistance when in comparison with black and copper fittings. Since corrosion typically accumulates erratically, totally different areas of your property might have totally different issues with low water stress. Electroplated galvanized steel pipe with wire plating, as are all steady plating, however different plating gear. Beneath is our record of the most continuously requested questions we’ve obtained about galvanized pipes. Galvanized steel plumbing pipes are pipes made of steel, and coated with zinc to forestall rusting. As soon as you have determined to exchange your galvanized pipes, there is no have to attempt to disassemble them, which would be a time-consuming and tough course of given that many of the joints are probably locked with corrosion. Prevents the Leaching of Lead into the Building Water Supply. As we speak, we will cover every thing you may must find out about learn how to cut galvanized pipes, and we’ll share three alternative ways you can minimize it at house. In the early 1900s lead and forged-iron pipes were replaced by galvanized pipe to be used with chilly water plumbing functions. As this corrosion progresses, it becomes obvious either as a result of the pipe corrodes by way of inflicting a leak, or as a result of corrosion scaling reduces the cross-sectional area of the pipe and the water stream via it. It is the stress piping, pressure piping design stress check preconditions strain pipeline is an important think about funding in infrastructure and pipeline reliability impression. When unsafe ranges of lead are found in ingesting water, the wrongdoer has usually been lead pipes or lead-containing brass and bronze fittings, however in a brand new examine researchers clearly show that lead present in the zinc coating of galvanized steel pipes generally is a very vital lengthy-time period source of lead in water. Different materials, the mechanical properties are totally different, the temperatures are in the usual – the corresponding worth on the strain gauge isn’t the identical. That is because of the lower value of galvanized pipe compared to copper or other supplies. Typically the threaded joints put on on the zinc coating of the pipes, which might shortly expose the metal beneath and trigger corrosion. After collecting baseline utilization knowledge on your own home’s plumbing system, the Flo by Moen system is able to detect irregularities and leaks It’s the smartest strategy to preserve a watchful eye in your outdated pipes, without having to maintain a plumber on velocity dial for the first signal of any issues. Start at the location where the pipes enter your own home, and discover the waterline. When installed correctly, fittings and pipes will create an efficient plumbing system. To find out a extra precise lifespan for your galvanized pipes, you should consider carefully concerning the environment you are inserting them in and communicate with a galvanized pipe distributor about your particular challenge. Due to the problems associated with galvanized pipes, many insurance coverage businesses will refuse to cowl houses that have them installed. If galvanized metal piping is used for dry and preaction programs, then an FM Approved nitrogen generator should be used for stress maintenance to forestall oxygen corrosion.

Materials that are typically used include alloyed steels, also known as stainless steel. With flame cutting, also known as oxygen cutting, a material is heated only to its ignition temperature. Oxygen is used as cutting gas so that the material burns and forms a pure stream of oxide that melts through the additional energy from burning.

The LCG 3015 is the latest addition to AMADA’s CO2 line of laser machines. The LCG was developed after listening to the voice of our customers who wanted a low-cost laser machine to meet their budget, but refused to compromise on cut quality, machine accuracy, and overall expandability. AMADA took these requests and achieved a machine that has a lower capital investment with a cutting edge resonator and an advanced motion system.

There are several different types of laser cutting available, including fusion cutting, oxidation cutting, and scribing. Laser cutting is a fabrication process which employs a focused, high-powered laser beam to cut material into custom shapes and designs. This process is suitable for a wide range of materials, including metal, plastic, wood, gemstone, glass, and paper, and can produce precise, intricate, and complex parts without the need for custom-designed tooling.

There’s no limit to the kind of laser cutters and engraving machines out there. You can pick up an entry-level option for under $200 if you’re interested in basic engraving on leather and vinyl stickers, or you can move your way up into the world of wood and metal. VEVOR Laser Engraver 50W CO2 Laser Cutter is the laser cutter and engraver on the higher price tag, but the powerful performance entirely justifies it. Although it isn’t suitable to cut and engrave metals, this machine is perfect for suitable wood, textile, industrial architectural modeling, specialty advertising, plastics, rubber stamps, picture framing and so on. The previous Bobs laser cutters are designed almost specifically for wood cutting.

Some of the laser cutting machines are manufactured with all these functions inbuilt such that one machine can perform a variety of applications. Some come with a control panel while others are controlled entirely from your personal computer. Be sure to keep in mind the most crucial factors, including the size of the bed and also the power of the lens and motor. Most of the laser cutting machines come accompanied by software which can be run on your desktop computer or laptop. This software aids in operating the machine, altering the settings to suit your needs and also design the elements to be engraved or cut out.

North America is expected to be a significant region, owing to the presence of robust industrial sector. The region accounted for over 31% revenue share in 2015 and is estimated to reach over USD 1.97 billion by 2024. Asia Pacific is projected to be the fastest-growing region owing to the presence of robust economies such as China, India, and Japan. The increasing adoption of laser systems in the manufacturing sector is boosting the regional growth. Moreover, the strong growth in industries that use laser cutting to produce semiconductors, consumer electronics, and automotive components is expected to drive demand.

Laser rebuild costs- With certain CO2 lasers, this cost can add $4.00/hour+- to your operating cost. Operating cost and cutting speed are the two most important cost drivers. When deciding which laser to use for a particular task, one must list all the requirements they look for and search for them in these types of lasers. These woodworking and metalworking plans are published for our visitors to let them create something for personal use. All works are licensed under a Creative Commons Attribution 4.0 International License. You would be amazed at how many places sell laser engravers with zero level of experience and absolutely no training or tech support.

Laser cutters are often operated two-dimensionally but, in some models, are also suitable for processing 3D items, such as pipes and profiles. Depending on the equipment included in the device, laser cutting also enables the production of three-dimensional openings. Today there are two popular types of laser cutting machines used in precision sheet metal fabrication, C02 and fiber. Fiber lasers boast extremely fast processing speeds and the ability to cut reflective materials which are not able to be processed using a C02 laser.

When speaking of metal forming in a press, however, you also are talking about the need to invest in tooling. Stamping also presents the ability to perform multiple tasks, such as forming and tapping, as part of the production process. The pre-filter and HEPA do their best to get rid of particle matter. However, there is also odors that come from cutting, especially plastics. For this reason, the Electrocorp also has 20 lbs of carbon granules.

The thermoelectric module acts as a small generator to power the fan motor. The improved hot air circulation and ensures greater comfort, while reduces the wood consumption of the stove. ❤ Energy saving❤ the thermoelectric module acts as a small generator to power the fan motor. The improved hot air circulation and ensures greater comfort ,while reduces the wood consumption of the stove. Many people still use an on/off switch for their shower fan. Either people turn the fan off after showering, which leaves a lot of moisture in the air, or they forget and leave the fan on, possibly for hours. I have two daughters who would sometimes leave the fan on all day until I found it running when I came home after work.

Be sure you use an approved termination cap where the vent piping exits your home. I’d give serious consideration to using foam core PVC pipe as the vent pipe for your fan. But if there is required, the 2 pipe and 4 pipe fan coil both can be equipped with an auxiliary electric heater to boost the heating capacity. When the air flow rate is raised to 1920 cfm, the velocity through the duct about doubles and the pressure increases 3-1/2 fold. If you’ve never heard of Valiant, then before you invest in a new stove fan, you owe it to yourself to read about their product lineup, just below. Their focus is on designing high quality products, stylishly designed and competitively priced.

We are sure that the above-mentioned product review certainly helps you in making a well-informed decision. We hope that things would have worked out for you and this article would have helped you to get the best wood stove pipe fan. However, if by some chance, the options we have provided do not interest you, then you must consider this US Stove MH8 Miracle 8″ Heat Reclaimer , Black as well. In an attic, the APEX Controller and attic fans work to control moisture and heat reduction through attic ventilation. However, the ATMOX setup is not just a set of venting fans in your attic space. It’s a smart solution using decades of research and science to bring the best system to your attic. In addition, ATMOX is adaptable to different attics that may vary by construction or climate. In many regions attic spaces tend to be very hot during the summer months. This hot air may cause damage to roof shingles and lead to an overuse of HVAC systems. With use of the APEX Controller and fans, your attic will benefit from heat reduction.

That gives you the lowest resistance and thus lowest back pressure possible short of replacing the roof jack. A bathroom fan MUST be vented to the exterior of the building to avoid moisture-related issues. When installing solid pipe, create a slight pitch toward the exterior of the building in case water condenses in the pipe. Remember to include the duct run length and any elbows in your calculations. Adding an elbow connector or an external vent hood with a backdraft preventer will add approximately 10 to 15 feet of duct length. You may need a higher CFM rated fan if your ductwork is long or complicated. Not venting a shower or improper venting can result in high humidity in the bathroom. When bathroom humidity builds up, warm moisture-laden air moves toward cooler wall surfaces, where it condenses back into water. These stoves need dedicated stove fans that have their best operating temperature range shifted towards around 150 centigrade. You might be surprised but there are quite a few Peltier fans designed to work on a low temperature stove top, and even one Stirling engine fan.

It’s usually best practice to vent bathroom fans to the outdoors. Bathroom exhaust fan performance is measured in cubic feet per minute , which gives the amount of air moved by the fan each minute. The product’s box will list the CFM number, and it will typically give a suggested room size as well. Some ceiling fans include lights and can be used to make a bathroom brighter or to replace an existing overhead or vanity light. However, due to their size and weight, the installation options may be more limited than they are with in-line fans. Control humidity and excess moisture in the bathroom with an exhaust fan. Learn what to look for in a quality model—and which models are top performers. Fan systems installed outside should not be audible inside unless there is an adjacent window that the occupants occassionally open and they spend time near to.

My first piece of advice is to buy the best fan you can afford. Fans that cost more money are almost always made with better parts and better motors, and they’re not noisy. You should run the fan for about 20 minutes during and after a bath or shower. That will help the fan fulfill its intended purpose of controlling moisture in your bathroom. If you run the fan constantly the ball bearings inside will lock up. Because windows provide light as well as ventilation, if you go the fan-only route you need to install artificial lighting. This should already be a given, as electrical code requires that habitable rooms be supplied with a switch-controlled light. Building code is a model code that each community can adopt and adapt according to its own needs. So, you will need to check with your city or county planning and permitting department to find out code requirements regarding bathroom fans.

According to the Ask the Electrician Web site, a bathroom fan should be left running for at least 20 minutes after a person gets out of the shower. This will ensure that all of the humidity is cleared out of both the room and the ventilation ductwork. PVC Schedule 40 Foam Core pipe is for drain, waste and vent purposes only. It is for non-pressure systems where temperatures will not exceed 140° F. PVC Schedule 40 Foam Core is lightweight, non-toxic and easy to install. Venting this fan into the attic is simply asking for problems. The excessive moisture will cause condensation on the roof members, insulation and eventually cause mold. Venting fans pull moisture-laden air out of that small space, slowing or altogether preventing it from condensing on walls, on the ceiling, or worst of all, inside the ceiling itself.
