[Tianjin Jinzhong Ji HVAC purification equipment to recommend the star product - the fan coil fan coil] usually installed directly in the air-conditioned room modular air conditioning prices, which served the state and worked to influence the quality of the indoor noise level and air quality. Therefore must be prepared to air filters, drip tray, coils, fans and other major components of routine maintenance worked to ensure that the normal role of fan coil air conditioner brands combined, does not adversely affected. 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 coarse filter, the hole is relatively large, 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 not clean, it will cause the coil to reduce the amount of heat exchange coil and cold water and drain off the air between the heat exchange efficiency of the coil so that 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. [Tianjin Jinzhong Ji HVAC purification equipment to recommend the star product - modular air handling units] is the core part of the surface of the cooler air handling units, air and refrigerant heat exchange places. Usually cooler coil structure by expanding machine for aluminum fins and brass Expansion. Brass wall thickness, the thickness of the aluminum foil slightly different manufacturers with different, generally brass wall thickness of 0.2 ~ 0.6mm modular air-conditioning, a diameter of 7 ~ 16mm, aluminum foil thickness of 0.15 ~ 0.20mm. It is noteworthy that different manufacturers fin pitch table selected during cold calculates a greater difference. Taking a system, for example, air volume of 79 000m3 / h, cooling capacity 831kW, Jia Chang's program to reduce the use of cooler fin spacing (about 1.8mm), to increase the heat transfer area; Yichang scheme adopted for selection Conventional fin spacing (about 2.5mm) ZK combined air conditioner, used in series in the form of a two-stage cooling section table, extend heat time. Two programs in the fan power, water resistance, and other aspects of cross-sectional dimensions of their advantages and disadvantages. The former may result in greater wind resistance thereby increasing the fan power, which may increase the unit size and flow resistance. After a thorough technical comparison and considering the cost factors that determine the use of Yichang products. This example illustrates the calculation cooler selection is related to the reasonableness of the use of the performance of the air handling unit and total cost, attention should be paid.
