The air-conditioning system design district, optional centralized air-conditioning systems. Air-conditioning systems form an independent choice of new wind and fan-coil system and a new air system, this can save energy can meet the requirements of the indoor environment. The design of cooling load calculation used by when the cooling load factor, calculated using the assumption that the hydraulic flow of hydraulic calculation software applications Hongye, all the graphics are used, such as CAD drawing.

This air conditioner of systems do not design the dividing area, select the centralized type air conditioner system for use. The systematic form of the air conditioner selects independent new trend and air blower serpentine system and the whole new trend system for use, so can can save the energy meet the internal environment requirement of the room as well as. Design cold load calculate, adopt cold load coefficient law chase, originally, water conservancy calculate, adopt, assu
