A fresh air treatment device with heat recovery

Abstract

The invention discloses a fresh air processing device with a heat recovery function. The fresh air processing device with the heat recovery function comprises a casing protective body and a connecting mechanism of the casing protective body and a window; an electrical control device, a forced air circulation device, a heat recovery micro-channel heat pipe exchanger and a separating plate are arranged in the casing protective body; the separating plate is used for separating fresh air from indoor exhaust air; the fresh air processing device is divided into two working areas through the separating plate; a heat pipe condenser is arranged in one working area; a heat pipe evaporator is arranged in the other working area; the heat pipe condenser, the heat pipe evaporator and a non-steam compression refrigeration piece are formed into a refrigeration system; the heat recovery micro-channel heat pipe exchanger is placed in a fresh air intake channel and an indoor exhaust channel. Accordingly, energy recovery can be performed first and then the fresh air can be cooled through refrigeration in the process of introduction of the fresh air and accordingly the purpose of further dehumidification and cooling can be achieved.

Description

technical field [0001] The invention relates to the application field of air conditioners, in particular to a fresh air treatment device with heat recovery. Background technique [0002] The early room fresh air cooling and heat recovery devices mainly used plate heat exchangers, rotary heat storage heat exchangers, etc. for central air-conditioning equipment. Most household split air conditioners do not include fresh air introduction devices. The indoor air quality is poor, and windows often need to be opened Realize the exchange of fresh air. During the exchange process, the adjusted air in the room will be lost in vain, wasting energy; some air conditioners also introduce some fresh air from the outside through the negative pressure of the evaporator. After the fresh air enters the room, the positive pressure formed in the room will The air in the room is exhausted from the room, the cooled air is exhausted in summer, and the heated air is exhausted in winter, causing a l...
