"Waterproof Cooling Fan" fan coil selection is the key issue. Press the largest selection of air-conditioned room cooling load of fan coil air conditioning system design is common practice, its purpose is to ensure that the peak load of the room temperature. And in fact, air-conditioned room to run most of the time would not be in peak load, so that the excess cooling capacity, and switching to low-grade run to reduce the cooling output, in order to maintain the heat balance of the room. Select "Waterproof Cooling Fan" fan coil units, in addition to cooling capacity to meet the requirements of the cooling load calculation, but also required to meet its match sensible heat and latent heat than the heat and moisture to meet the requirements of the room; air volume required to meet the supply air temperature, change the number of gas and air distribution and other requirements. "Waterproof Cooling Fan" as central air-conditioning fan coil terminal equipment, its quality determines the effects of indoor air conditioning. Meanwhile, the cleaning problem directly affects the use of central air-conditioning effect.
