摘要
该文介绍一种分散式固体除湿机,对回风除湿降温,使用室外空气再生。研究在3个典型气候区的城市,即广州、北京、哈尔滨的夏季空调设计室外参数除湿机的性能。结果表明:最优转换时间下,在讨论的换气次数和除湿板厚度下,在干燥的哈尔滨,除湿机的再生温度t_(reg)为28.4~42.2℃,在潮湿的广州,除湿机的t_(reg)为34.8~67.9℃;机组采用热泵驱动时,利用太阳能附属加热器,除湿机应用在广州、北京、哈尔滨三地时的系统COP分别为3.28、5.19、7.51。
A new decentralized solid dehumidifier is introduced in this paper,which is designed to cool and dry the indoor air and to use the outdoor air for regeneration.Summer air conditioning working conditions of three typical cities,namely Guangzhou,Beijing and Harbin,in three typical climate zones are selected to analyze the performance of this dehumidifier applied in residential buildings.The results show that when the dehumidifier works under the optimal switching time,the regeneration temperature in Harbin and Guangzhou is from 28.4℃to 42.2℃and from 34.8℃to 67.9℃,respectively.When the dehumidifier is driven by heat pump,with the assistance of solar heating,system COP of the dehumidifier applied in Guangzhou,Beijing and Harbin are 3.28,5.19 and 7.51,respectively.
