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 heating, ventilating and air-conditioning systems, and relates to a combined fresh air treatment device for solution total heat recovery, condensation and dehumidification. Background technique [0002] In the air conditioning system, according to the requirements of the current national health standards, a certain amount of fresh outdoor air (fresh air) needs to be supplied to the room. National HVAC-related standards generally stipulate the minimum fresh air volume (m 3 / h). Due to the temperature, humidity and dust content, the outdoor fresh air usually cannot be directly sent into the room, and must be subjected to heat and humidity treatment. During the cooling season, the outdoor air is usually high temperature and high humidity, which requires cooling and dehumidification of the outdoor air; during the heating season, the outdoor air is usually low temperature and low humidity, and the outdoor air needs to...
