Abstract

The invention discloses a heat-pump-driven indirect evaporative cooling return air total heat recovery fresh air treatment device. The heat-pump-driven indirect evaporative cooling return air total heat recovery fresh air treatment device comprises a return air treatment system, a fresh air treatment system and a mechanical refrigeration system. The return air treatment system comprises a return air-water heat exchanger and a plurality of spraying filler modules which are connected in sequence. The fresh air treatment system comprises a supply air-water heat exchanger, a surface air cooler and a plurality of fresh air-water heat exchangers which are connected in sequence. According to the heat-pump-driven indirect evaporative cooling return air total heat recovery fresh air treatment device, irreversible loss in the heat and mass transfer process can be effectively avoided, the total heat recovery efficiency of the systems is improved, the cooling capacity input by a cold source is reduced, and the total energy efficiency of the fresh air treatment device is improved.

Description

Technical field [0001] The invention belongs to the field of HVAC systems and relates to a fresh air processing device. 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 supplied to the room (m 3 / h). Due to temperature, humidity, and dust content, the outdoor fresh air usually cannot be directly sent indoors 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 usually has low temperature and low humidity, and outdoor air needs to be warmed and humidified. Heat and humidity treatment of outdoor air is one of the main tasks of the air conditioning system. The energy consu...
