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

The invention discloses an efficient fresh air dehumidifier based on heat recovery and double-evaporation temperature of a heat pump. The efficient fresh air dehumidifier comprises two parts including an inner machine and an outer machine. Compared with outdoor air, the temperature and humidity of exhaust air in an air conditioning room are low, and the exhaust air in the air conditioning room is a cold source with a certain grade. According to the efficient fresh air dehumidifier, a heat recovery mode of the heat pump is adopted, the indoor exhaust air passes through a heat recovery exchanger under the action of an exhaust fan, so that refrigerant is condensed by the exhaust air, and then the refrigerating capacity in the exhaust air is transferred to an evaporator so as to cool fresh air by virtue of a refrigerating cycle, so that the effect of recovering energy is achieved. On the other hand, the heat recovery exchanger is used, so that the heat exchange on the condensing side of a refrigerating system is improved, and the condensing pressure of the whole system is reduced. Under the synthetic action of the heat recovery exchanger and the refrigerating system, the energy efficiency ratio of the fresh air dehumidifier can be effectively increased.

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 (in summer), if the fresh air enters the room directly, it will increase the indoor cooling load while increasing the indoor humidity. 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 then reheat...
