1. The main control unit selection parameters rated air flow outlet static pressure, input power, rated cooling capacity, rated for heat, noise, water resistance and so on. 2. The fan coil unit air about 250 ~ 2500m / h, exit static pressure is less than 100Pa (exit static pressure greater than 30Pa for high static pressure type). 3. The selection of the unit should be room specifications cold, heat and air heat and moisture loads than other factors to determine: 1) if the fresh air and room air enthalpy parameters, fan coil units only burden the cold room envelope and internally generated, heat load; 2) When a new air enthalpy value is greater than or less than the room air enthalpy small horizontal fan coil air flow, fan coil units should be added or deducted part of the new air-cooled heat load; 3) when the absolute moisture content of fresh air When the amount is less than room air moisture content, wet load can all afford hospital room horizontal fan coil units, fan coil affordable room only sensible heat load, should be configured according to the dry conditions; vertical surface mounted fan coil units in summer for cold water temperature not lower than 7 ℃, winter heating water temperature not higher than 80 ℃, the use of cold and hot water must consider the local water conditions soften. l unit maximum allowed pressure 1.6MPa. l filter should be cleaned regularly. l exchanger cleaned regularly and kept clean to ensure good heat transfer. l After power horizontal fan coil, fans should start to observe the direction of rotation is correct. l If the unit installed in the dark, to be provided with access doors for easy maintenance perennial. l When the maintenance crew, should cut off the power.
