The working principle of the fan coil air conditioning system is to continuously circulate the indoor air by means of the fan coil unit, so that it is cooled or heated through the coil to maintain the required temperature and a certain relative humidity of the room. The cold or hot water used in the coil is supplied by a centralized source of cold and heat. At the same time, the fresh air after centralized treatment by the fresh air-conditioning room is sent to each air-conditioned room through a special fresh air duct to meet the sanitary requirements of the air-conditioned room. Compared with the centralized system, the fan coil air conditioning system has no large air ducts, only water pipes and small new air ducts. It has the advantages of convenient layout and installation, small occupied building space, and independent adjustment. It is widely used for temperature and humidity precision. Comfortable air conditioning with low requirements, large number of rooms, small rooms, and separate control.
