摘要
以某空调系统为例,利用新风换气机、转轮全热换热器、风冷热泵等余热回收技术,针对新风系统进行改造,回收排风中的能量.对热回收系统进行经济性分析,这三种能量回收装置均适用于排风热回收系统,运行费用比原空调系统节约了33%~35%.其中,风冷热泵排风热回收系统从整体分析,略优于其他两个方案.
Three heat recovery systems from exhauster air by fresh air exchanger,rotary wheel exchanger,and air source heat pump were presented,which were rebuilt from a fresh air system at Hunan province.The economic analysis on these heat recovery systems proves that these devices are applicable for heat recovery from exhauster air,and the running cost are decreased about 33%~35% than that of the original system.Air source heat pump is worth to be recommended for heat recovery from exhauster air because it is superior to other devices.
