Problems solved by technology

Because the evaporation temperature of the traditional fresh air dehumidifier is very low, and the cold / heat in the exhaust air is not recovered, the energy efficiency of the traditional fresh air dehumidifier is low and the energy consumption is huge

Abstract

A high-efficient fresh air dehumidifier based on heat pump heat recovery and dual-evaporation temperature, comprising two parts: an indoor unit and an outdoor unit. By means of heat pump heat recovery, the indoor exhaust air passes through a heat recovery exchanger (4) under the action of an exhaust fan, so that the exhaust air condenses a refrigerant, and then the refrigerating capacity in the exhaust air is transferred to an evaporator (6) to cool fresh air by means of a refrigerating cycle, thus achieving the effect of recovering energy.

Description

technical field [0001] The invention relates to a fresh air dehumidifier, in particular to a high-efficiency fresh air dehumidifier based on heat pump heat recovery and dual evaporation temperatures. Background technique [0002] In the air-conditioning system of a building, the indoor air quality is often improved by introducing outdoor fresh air. However, because the outdoor fresh air is humid and hot (summer), if the fresh air directly enters the room, it will increase the indoor humidity and increase the indoor cooling load at the same time. Therefore, it is generally required to dehumidify the fresh air in advance. [0003] The fresh air dehumidifier bears all the indoor humidity load and part of the heat load, and is often matched with indoor sensible heat treatment equipment (such as radiant air conditioning system). The principle of the traditional fresh air dehumidifier is to cool down the air temperature to the dew point through the evaporator to dehumidify, and t...
