Module fresh air conditioner is a solution of environmental intelligent control provided by Ticom Tech based on the energy saving air conditioner for the communication base station and the  intelligent fresh air for the Communication Bureau (station). It is based on the precision air conditioning, and adds the intelligent fresh air function. The module fresh air is used as the redundant backup of the precision air conditioning. After the air conditioning is retreated, it provides emergency backup. The module can start work  according to the working temperature of fresh ai , so as to keep the difference between the room temperature and outdoor temperature be no more than△T (default 3℃) 

Working principle: module fresh air conditioner is a system that controls the temperature in the machine room by combing fresh air and conditioner control. When the room temperature sreaches 22 degrees Celsius (can be set), and the temperature difference between indoor and outdoor is no less than 2℃, the module fresh air equipment will start and send filtered cold air to indoor. When the indoor temperature drops to 18 ℃, the module fresh air will stop. When the indoor temperature continues to rise to 25 ℃, the module fresh air will stop, and the module precision air conditioner will start refrigeration. When the indoor temperature is reduced to 23 ℃, the module precision air conditioner will stop working and wait for the next working process. It works in a cycle way.
