Radiation air-conditioning system, as a kind of energy-saving air-conditioner, achieves a good energy-saving effect by combining with low energy consumption or green buildings.

In the same designed temperature, the second program can raise the supply air temperature, and then, reduce air conditioning's cooling load and energy consumption.

The energy consumption in a hotel is mainly caused by air condition. Thus, it is very important to design a rational air condition control system to improve the utility of energy.
