Description

Technical Field

[0001] The invention belongs to the technical field of home decoration, and in particular to an intelligent fresh air system. Background Art

[0002] The fresh air system is an independent air treatment system consisting of an air supply system and an exhaust system. It is divided into two types: ducted fresh air system and ductless fresh air system. The ducted fresh air system consists of a fresh air fan and duct accessories. The fresh air fan purifies the outdoor air and introduces it into the room, and then exhausts the indoor air through the duct; the ductless fresh air system consists of a fresh air fan, which also purifies the outdoor air and introduces it into the room. Relatively speaking, the ducted fresh air system is more suitable for industrial or large-area office areas due to the large amount of engineering, while the ductless fresh air system is more suitable for home use because of its easy installation. In 1935, after many attempts, Chun Yi invented and manufactured the world's first heat exchange equipment that can filter air pollution, also known as a fresh air system.

[0003] The fresh air system is based on the use of special equipment to deliver fresh air to the room on one side of the closed room, and then exhaust it to the outside from the other side by special equipment, forming a "fresh air flow field" in the room, thereby meeting the needs of indoor fresh air ventilation. The implementation plan is: use a high-pressure, large-flow fan to deliver air to the room from one side by mechanical force, and exhaust it to the outside from the other side by a specially designed exhaust fan to force the formation of a fresh air flow field in the system. While delivering air, the air entering the room is filtered, disinfected, sterilized, oxygenated, and preheated (in winter).
