双逆流式露点间接蒸发冷却器的性能试验研究
Experimental study on the performance of a double countercurrent dew-point indirect evaporative cooler
摘要
Abstract
In order to use evaporative coolers in residential buildings to achieve a greater cooling temperature difference and reduce the size of the dew point core,a double countercurrent dew point indirect cooler was proposed,which combines double countercurrent design and efficient wet channel material.In the double enthalpy difference test room,by using dry bulb temperature of 35℃and wet bulb temperature of 25.8℃as the example,the cooling efficiency and cooling capacity,etc.of this cooler were analyzed.The results show that in the medium-humidity region,the secondary/primary air volume ratio is 0.9.When the spraying method of 15 s stop for 60 s is used,the wet bulb efficiency of the cooler reaches 104%,the dew point efficiency reaches 79%,he cooling capacity reaches 1.76 kW,and the highest COP is 7.5,which can meet the requirements of the indoor air supply temperature of 26～28℃and the energy consumption reduction in residential buildings.The study can provide a reference for the design of dew point air conditioners for residential buildings.关键词
