[Tianjin Jinzhong Ji HVAC purification equipment to recommend the star product - a certain amount of fan coil] fan coil air, water temperature is constant, the amount of change in the water supply, cooling capacity with horizontal concealed fan coil water volume changes The changes, according to the part of the fan coil performance statistics, when the water temperature is 7 ℃, reducing the amount of water to 80% of the original cooling capacity of around 92%, indicating that when the amount of water changes affect the cooling capacity is relatively slow. Fan coil supply and return water temperature constant, when the water temperature rises, the cooling capacity with the reduction, according to statistics cassette fan coil, when the water temperature rises 1 ℃, reduce the cooling capacity of about 10%, the higher the water temperature, the greater the reduction in air-conditioning fan coil, dehumidification capacity decreased. Certain water conditions, when the fan coil air volume change, cooling capacity and air treatment enthalpy difference varies, generally reducing vertical surface mounted fan coil cooling capacity, enthalpy difference increases, the unit cooling capacity of the fan power changed little. Fan coil inlet, when the water temperature difference increases, reducing the amount of water, the heat transfer coefficient of heat exchange coil decreases. In addition, the temperature difference has changed, therefore, fan coil cooling capacity increases with the supply and return water temperature is reduced, according to statistics when the water temperature is 7 ℃, supply and return water temperature increased from 5 ℃ to 7 ℃ When the cooling capacity can be reduced by about 17%. Thermal Environmental Conditions refers to the combined effect of physical parameters on human thermal comfort happened. These physical parameters including air dry bulb temperature, relative humidity, air velocity, mean radiant temperature, the body's metabolic rate and clothing and other six. Wherein, the air temperature and the flow rate is an important parameter to evaluate comfort conditions provided by fan coil thermal environment. [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 aluminum foil with different manufacturers vary slightly, generally brass wall thickness of 0.2 ~ 0.6mm, 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), using two-meter section of the series in the form of cold, prolonged 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.
