不同除湿方式户式辐射空调系统能耗研究

Energy consumption of household radiation air conditioning systems with different dehumidification modes

模拟比较了冷水式除湿、制冷剂直膨式除湿、双冷源除湿3种除湿方式下户式辐射空调系统的夏季供冷能耗。结果显示:3种除湿方式下,空调房间温度均能满足要求,采用制冷剂直膨式除湿时室内温度略低,双冷源除湿时室内温度略高;采用制冷剂直膨式除湿的户式辐射空调系统能耗最低,冷水式除湿能耗最高,直膨式除湿的能耗较冷水式除湿约低15%,较双冷源除湿约低10%。

Simulates and compares the summer cooling energy consumption of household radiation air conditioning systems under three dehumidification modes of water cooling dehumidification,refrigerant direct expansion dehumidification and double cold source dehumidification.The results show that the temperatures of the air-conditioned room are all in the demand range,and the indoor temperature is slightly lower when using refrigerant direct expansion dehumidification and slightly higher when using double cold source dehumidification.The energy consumption of the household radiation air conditioning system with refrigerant direct expansion dehumidification is the lowest,and that with water cooling dehumidification is the highest.The energy consumption of direct expansion dehumidification is about 15%lower than that of water cooling dehumidification and about 10%lower than that of double cold source dehumidification.
