Coil: coil charged with hot and cold water to cool the heat transfer to the air through the fan coil important mission. In order to ensure efficient heat transfer, requiring the coil surface must be kept clean. However, due to the fan coil units are generally equipped with early effect filters, perforations larger refrigeration cooler, at the beginning of use, it is inevitable that passes through the filter and dust attached to the surface of the pipe or fin coil. If the supply is not promptly clean cooler, it will make the coil to reduce the amount of heat exchange coil and cold water and drain off the air, thereby making the coil heat exchanger effectiveness can not be fully realized. If a lot of dust adhesion, and even part of the air passage between the ribs are blocked, then the same time also reduce the air supply fan coil, so that the air conditioning performance is further reduced. As a central air conditioner cooler air-conditioning equipment indispensable core components cooler brass, is one of the main part of the central air conditioning system, it is mainly played the role of energy release. So its quality cooler, directly related to the ability to meet the design effect, creating a comfortable indoor environment, and create a warm living areas. AHU fan coil cooler, cold air flowing through the air conditioning inside the chilled water (coolant water) flowing through the outside of the air-cooled heat exchanger fins, fans would be cool to use place after cooling, chilled water Table cooler return pipe back to the heat absorbed by the cooling unit, giving off heat, cool and then was sent back to cooler absorbs heat, cooling air flows constantly circulating. Cooler supply, Vanke air conditioning (certified), coolers provided by Vanke Air Conditioning Equipment Co., Texas. Vanke Air Conditioning Equipment Co., Texas (www.dzwkkt.com) (www.dzwkkt.com) is Dezhou, central air conditioning leader, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs. Vanke conditioning leadership with the staff warmly welcome all inquiries negotiations to create a better future for China Vanke air conditioning.
