Problems solved by technology

[0005] The existing solid dehumidification technology is mainly used in the dehumidification of the rotor, the air duct is fixed, and the moisture absorption and regeneration are realized through the rotation of the rotor, the structure is complex and the cost is high
In the few systems that use sprayed adsorption layer heat exchangers for dehumidification, the air ducts are also fixed. Multiple air valves are set on the air intake and return air ducts to control the flow direction of the new return air. The structure and control are relatively complicated.

Abstract

The invention relates to a primary air system. The primary air system comprises a main body air duct and reversing air ducts; the main body air duct comprises a first cavity and a second cavity; moisture absorbing materials capable of absorbing moisture for air flows are arranged in both the first cavity and the second cavity; each reversing air duct comprises a movable part, and the movable part can move relative to the main body air duct to enable the reversing air duct has at least two working modes; when the reversing air ducts are in the first working mode, primary air is sent into a room via the first cavity, the moisture absorbing material in the first cavity can absorb the moisture, and return air is exhausted out of the room via the second cavity; when the reversing air ducts are in the second working mode, the primary air is sent into the room via the second cavity, and the return air is exhausted out of the room via the first cavity; the moisture absorbing material in the second cavity can absorb the moisture; and the moisture absorbing material in the first cavity can be regenerated. Switching of moisture absorption and regeneration of the moisture absorbing materials is realized through switching of the reversing air ducts between the first working mode and the second working mode, and dehumidified primary air can be continuously supplied into the room.

Description

technical field [0001] The invention relates to the field of air conditioning, in particular to a fresh air system. Background technique [0002] With the increasing popularity of air-conditioning, in addition to basic cooling and heating functions, people's requirements for improving the quality of the indoor environment and the comfort of the air-conditioning system are also getting higher and higher. The radiant air-conditioning system is used in conjunction with the fresh air dehumidification system, which can just meet people's requirements for comfort and air quality. [0003] However, traditional fresh air dehumidifiers use vapor compression cooling and dehumidification technology to focus on the sensible heat and latent heat load of fresh air, resulting in high energy consumption of the unit, which deviates from the national energy-saving and emission-reduction policy. Solid dehumidification fresh air air conditioner, spray an adsorption layer on the surface of the ...
