热泵型冷热源及热回收系统在精密空调节能改造中的应用

Application of heat pump type cold and heat source and heat recovery system in energy-saving renovation of precision air conditioning

针对某科研院所精密空调机房内排风余热利用率偏低现状,根据某楼宇空调机房内新风机组实际应用状况,设计并安装热泵型冷热源及热回收系统。统计安装热泵型冷热源及热回收系统前后的用电量,经全年运行结果表明安装热泵型冷热源及热回收系统后节电率为41.2%,节约电费约225598.85元,节能效果十分显著。

In response to the low utilization rate of exhaust heat in the precision air conditioning room of a certain research institute,a heat pump type cold and heat source and heat recovery system are designed and installed based on the actual application status of the fresh air unit in the air conditioning room of a certain building.Statistics on the electricity consumption before and after the installation of heat pump type cold and heat sources and heat recovery systems show that the annual operation results show that the energy-saving rate after the installation of heat pump type cold and heat sources and heat recovery systems is 41.2%,saving about 225598.85 yuan in electricity costs,and the energy-saving effect is very significant.
