梅雨季节下重力循环柜性能实测研究

Experimental Study of Gravity Circulation Cabinet Performance on Rainy Season

通过搭建重力循环柜试验平台,测试重力循环柜在梅雨季节下的供冷除湿情况。选择江苏昆山作为高湿地区代表,研究供水温度、供水流量等变量对重力循环柜运行性能的影响,并探究供水温度和供水流量对毛细管壁温升、室内温湿度、室内人体热舒适和室内环境响应速度的影响。结果表明:在梅雨季节,重力循环柜的供冷除湿性能稳定良好,供冷量为1200~1800 W,除湿量为0.5~1.0kg/h;室内温度为23~24℃,相对湿度为50%~65%;室内环境响应速度较快,当改变房间的设定温、湿度时,调节供水温度比调节供水流量更有效。

The cooling and dehumidification performance of gravity circulation cabinet on rainy season was established and tested.The Kunshan district was selected as representative high-humidity area.The influence of water temperature and water flow rate on gravity circulation cabinet performance were tested,and the changes of capillary temperature,indoor temperature and humidity,human thermal comfort,environmental response were explored.The experimental results show that the gravity circulation cabinet has stable cooling and dehumidification performance on rainy season,the cooling capacity of gravity circulation cabinet is 12001800 W,the dehumidification capacity is 0.51.0 kg/h;the indoor temperature is 2324℃and the relative humidity is 50%65%.The indoor environment is more responsive,adjusting the circulating water temperature is more effective than circulating water flow when changing the indoor temperature and humidity.
