The saving energy principle of this system is: when the base station needs to cool and decrease the temperature, it will treat outdoor air as the cooling source and through ventilates or the heat interchanger to decrease the temperature. When the outdoor air heat sink cannot satisfy the temperature decreasing request, it starts the indoor air conditioning to cooling. Thus, in spring, autumn, winter or night, the temperature is low, it decrease the temperature by outdoor air so that it can saving much electricity energy using by air conditioner. The function of this system achieved is to control the fan’s run or stop and the fans and air conditioner linkage by a certain intelligent calculating the detected the temperatures of indoor and outdoor and other parameter. Through the superior machine management software, it can real-time monitor operational aspect of various part.

The controller use 160*240 LED, blue background and white letter. It can display system’s working status, parameter setting, history record and pass word input information, etc
