the same layer into the interior of the new air handling units, fan coil independently indoor hot and cold load. Fresh air supply fan coil set up a new way for a single air system, the independent supply
room. Layer of larger space, more staff, fluctuations in temperature and humidity range of allowable values of small shopping malls, all-air system. The introduction of outdoor air directly from mixing air (a) after the return air conditioning room into. Because of the various types of hotel rooms, the room is not the same, individual heat load on the individual. Room, The design of air conditioning water system selection process, and the vertical closed with different levels, control and program flow pumps, water system, air system, the structure is simple, initial investment, not easy to generate dirt and pipe system, does not need to overcome the corrosion of hydrostatic pressure pump head, small power etc.
KEY WORDS: the cooling load of the air-conditioning system, Water system, primary return air system , fan coil system
