[0002] The constant temperature and humidity material room air-conditioning unit refers to the air-conditioning equipment that provides fresh air that has been filtered, pressurized, dehumidified and reduced humidity (or heated) for places where composite materials have special requirements for temperature and humidity. The constant temperature and humidity material room air-conditioning unit is an integrated model with air cooling mode. The unit is easy to install and use. The constant temperature and humidity material room air-conditioning unit is an environmental control equipment for composite material rooms and has become one of the necessary equipment in composite material rooms. The air conditioning fresh air system is one of the three major air circulation systems of air conditioning, namely indoor air circulation system, outdoor air circulation system and fresh air system. The main function of the fresh air system is to realize the circulation and ventilation between room air and outdoor air, as well as to purify the air. In order to better ensure the effect of air purification, the air needs to be filtered.

[0003] At present, constant temperature and humidity material room air conditioning units are usually installed with air filtering devices, and most of them are independent devices, usually connected to the outside of the constant temperature and humidity material room air conditioning components, occupying a large space. The filter used for filtering is often directly fixed and installed with screws, which is more troublesome when disassembling the filter, making it inconvenient to clean and replace the filter, greatly reducing the effect of air filtration.
