Abstract

The invention discloses a solution total heat recovery and condensation dehumidification compound fresh air processing device, which comprises a return air processing system and a fresh air processing system, wherein a sensible heat exchange device is adopted, supply air with lower temperature is utilized for lowering the temperature of indoor return air, meanwhile, the supply air temperature of fresh air is also raised, and the fresh air can be directly supplied into a room. The state point of return air before entering a total heat recovery device approaches to a saturation line, the return air and the fresh air are subjected to total heat recovery in the solution total heat recovery device, the recovered energy of the return air is fully utilized, the input cold quantity of a cold source is reduced, and the energy efficiency of the fresh air processing device is improved. In addition, the fresh air processing device has the advantage that through work condition switching, the return air heat recovery and fresh air heating and dehumidification functions in winter can be realized.

Description

Technical field [0001] The invention belongs to the field of HVAC systems and relates to a composite fresh air treatment device for solution total heat recovery and condensation and dehumidification. Background technique [0002] In the air-conditioning system, a certain amount of fresh outdoor air (fresh air) needs to be supplied indoors in accordance with the requirements of the current national health standards. National HVAC standards generally stipulate the minimum amount of fresh air (m 3 / h). Due to temperature, humidity, and dust content, the outdoor fresh air cannot usually be sent into the room directly and must be treated with heat and humidity. During the cooling season, outdoor air is usually high temperature and high humidity, and outdoor air needs to be cooled and dehumidified; during the heating season, outdoor air is usually low temperature and low humidity, and outdoor air needs to be warmed and humidified. Heat and moisture treatment of outdoor air is one of ...
