The fresh air filter unit is an air conditioning device that provides fresh air. Functionally, it can achieve constant temperature and humidity or simply provide fresh air according to the requirements of the usage environment. Its working principle is to extract fresh air from the outdoors through dust removal, (or humidification), cooling (or heating) and other processes, and then send it into the indoor space through a fan to replace the original indoor air when entering the indoor space. Of course, the above functions must be determined according to the needs of the usage environment. The more complete the function, the higher the cost.

The difference between a fresh air filter unit and an air conditioning unit is that the fresh air filter unit is used to handle fresh air. In a large building, the fresh air unit is usually used in conjunction with a fan coil unit, while the fan coil unit and fresh air filter unit are actually similar to an air conditioning unit. In general, the air conditioning unit itself has fresh air outlets, which are used to improve indoor air quality and supplement indoor exhaust. Due to the lack of fresh air outlets in the fan coil unit, it is necessary to provide fresh air filtration units. The treated fresh air provided by the fresh air filtration unit and the return air treated by the fan coil unit can either be mixed first and then processed by the fan coil unit before being sent into the room.
