The principle of fresh air system is that in a closed room, fresh air is sent into the room by special equipment on one side and then discharged out of the room by special equipment on the other side, and a "fresh air flow field" will be formed indoors, thus meeting the needs of fresh air ventilation in the room. The implementation scheme is as follows: the centrifugal fan is driven by a high-pressure head and a high-speed DC brushless motor with large flow and low power, and blows air into the room from one side through mechanical force, and the other side forcibly forms a fresh air flow field in the system through a specially designed fresh air exhaust fan. At the same time of air supply, the air entering the room is filtered, disinfected, sterilized, oxygenated and preheated (in winter). When the exhaust air passes through the main engine, it exchanges heat with the fresh air, and most of the recovered energy is sent back indoors through the fresh air. Make use of the scheme of forming clean space on a large scale to ensure that the air entering the room is clean. In this way, indoor air can purify the environment.

The traditional air conditioning fresh air system has no ventilation path design and exhaust measures, which can not effectively eliminate indoor dirty air, and there is a great risk of cross-infection in the system. Adopt dynamic distributed ventilation system to realize the on-demand control of fresh air volume in each room. Through special intelligent control system software, all hosts can be regulated and controlled in the remote monitoring station to monitor the running state of each host. The host can realize intelligent induction adjustment, and can effectively monitor and manage the system remotely.
