Background
The fresh air system is a set of independent air processing system consisting of an air supply system and an air exhaust system and is divided into a pipeline type fresh air system and a pipeline-free fresh air system. The pipeline type fresh air system consists of a fresh air fan and pipeline accessories, outdoor air is purified by the fresh air fan and is led into a room, and indoor air is discharged through a pipeline; the ductless fresh air system is composed of a fresh air fan, and the fresh air fan is used for purifying outdoor air and guiding the outdoor air into a room. Relatively speaking, the pipeline type fresh air system is more suitable for being used in industrial or large-area office areas due to large engineering quantity, and the pipeline-free fresh air system is more suitable for being used in families due to convenient installation. After many attempts, the first heat exchange device capable of filtering air pollution in the world, also called a fresh air system, is invented and manufactured. The fresh air system sends fresh air to the room by special equipment on one side of the room and discharges the fresh air to the outside from the other side of the room, and a fresh air flowing field can be formed indoors, so that the requirement of indoor fresh air ventilation is met. The implementation scheme is as follows: the new wind flow field is formed in the system by adopting a high wind pressure and large flow fan, supplying air from one side to the indoor by means of mechanical strength and discharging the air from the other side to the outdoor by a specially designed exhaust fan. The air entering the room is filtered, disinfected, sterilized, oxygenated and preheated (in winter) while the air is supplied.

The temperature and humidity independent control air conditioning system applying the fresh air to deeply dehumidify enables the fresh air to independently bear all indoor humidity loads, so that the tail-end circulating unit can operate under a dry working condition, and can control the indoor temperature by using higher freezing water temperature, thereby realizing the independent control of the temperature and the humidity. The temperature and humidity independent control air conditioning system can increase the temperature of cold water for treating sensible heat load from the traditional 7 ℃ to about 17 ℃, so that the COP of the refrigerating machine is increased by more than 40 percent, and the energy consumption of the centralized air conditioning system is reduced by more than 30 percent.
