调湿型新风机组在户式中央空调工程中的应用

Applicationof Humidity Controlby Fresh Air Handling Unit in Household Centralair Conditioning Project

一般家用空调系统只进行温度控制,湿度为被动调节,导致室内人员的舒适感较差。本文介绍了一种在户式中央空调系统内设置调湿型新风空调器的方案,通过在新风空调器内设置两级压缩制冷系统,对新风进行深度除湿,新风承担部分室内湿负荷,从而实现室内湿度的主动调节。同时通过回收利用除湿制冷排放的冷凝热提高新风送风温度来实现潮湿季节房间内供热除湿的需求。

The household air conditioning system general controls the temperature and the humidity is passive,These lead to the poor comfort of the indoor personnel. This paper introducesa set ofthe humidity control by fresh air handling unit in the household central air conditioning system,by settingthe two stage compression refrigeration system in the fresh air conditioner,itcan carry out the deep dehumidification of fresh air,and the fresh air supports part of indoor humid load,so as to achieve the active regulation of the indoor humidity. At the same time,the demand of heating and dehumidification in the wet season is realized by using the condensing heat of the dehumidification refrigeration to improve the temperature of the fresh air supply.
