What exactly is a fresh air system?

Fresh air system is an independent air handling system, which consists of air supply system and exhaust system.

Fresh air system: it consists of machine, air inlet, air outlet, filter box and various pipes and joints. Installed in the ceiling of the kitchen or bathroom, the machine is started, the polluted air in the room is discharged to the outside through the air outlet, and the fresh air in the outside enters the room through the filter box and the air inlet, so that indoor personnel can breathe high-quality fresh air.

Moreover, considering the saving and reuse of energy, the exhausted air is heat recovered, and the recovery rate reaches over 80%, which is used as new energy.

In order to pursue a healthy and quiet quality of life, 70 years ago, European countries produced a simple and practical system. The system has been installed in 90% buildings and has been widely used. This is the central fresh air system.

The system continuously and efficiently circulates the indoor and outdoor air of the whole house for 24 hours, which is an air replacement system to ensure the indoor air quality. Ensuring that there is fresh air indoors at all times is dubbed as "the respiratory system of the house".

Extended data

The fresh air system uses special equipment to send fresh air into the room on one side of a closed room, and then uses special equipment to exhaust it to the outside on the other side, which will form a "fresh air flow field" indoors, thus meeting the needs of indoor fresh air ventilation.

The implementation scheme is as follows: a fan with high wind pressure and large flow rate is used to blow air into the room from one side by mechanical force, and a specially designed exhaust fan is used to exhaust the air from the other side to forcibly form a fresh air flow field in the system. At the same time of air supply, the air entering the room is filtered, disinfected, sterilized, oxygenated and preheated (in winter).
