What is the symbol of the central air conditioning fresh air system?

The outdoor air is purified and sent indoors. The main function is to ventilate and increase oxygen to prevent suffocation, and can effectively purify indoor harmful substances. The so-called "center" means that the host reaches multiple air outlets through pipes.

The fresh air system renews and replaces the indoor air to maintain fresh indoor air. The central air conditioner adjusts the indoor temperature. There is an essential difference between the two. The Haoting fresh air system is composed of a fresh air host and a breathing system. An independent air treatment system and a fresh air ventilator filter and purify the fresh outdoor air and transport it indoors through pipelines. Principle: The fresh air system is based on the use of special equipment on one side of a closed indoor room to send fresh air into the room, and then discharge it to the outside through the special equipment on the other side. A "fresh air flow field" will be formed indoors to meet the needs of indoor fresh air ventilation. . The implementation plan is to use a high-pressure head, large-flow, low-power, high-speed brushless DC motor to drive a centrifugal fan, rely on mechanical force to supply air from one side to the room, and use a specially designed exhaust fresh air fan to discharge it to the outside from the other side. A fresh air flow field is formed within the system. While supplying air, the air entering the room is filtered, disinfected, sterilized, oxygenated, and preheated (in winter).
