摘要
根据空调排风热回收技术存在的问题,通过具体实例,针对具体地区,分析了需选择的不同排风热回收方式,以达到真正的节能效果。主要应用动态温度和动态效率的方法,对厦门某公共建筑中所采用的热管式排风热回收技术进行节能性和经济性计算与分析,得出热管式排风热回收技术不适合用在夏热冬暖地区。通过对比显热回收与全热回收的节能效果,得出厦门地区排风热回收的适用形式。此文总结出并非所有空调系统只要采用了排风热回收技术就一定能达到节能、经济目的。
The energy saving effect of practical example is analyzed based on the problems of exhaust air heat recovery in air conditioning technology. The energy and economic efficiency of heat pipe type exhaust heat recovery used for a public building in Xiamen are calculated and analyzed by the dynamic temperature and dynamic efficiency method, with the conclusion that heat pipe type exhaust heat recovery technology doesn＇t suit for the hot summer and warm winter areas. The applicable forms of exhaust heat recovery in Xiamen are acquired by comparing the effects of sensible heat recovery and total heat recovery. And get that not all air conditioning systems using exhaust air heat recovery are energy-efficient or economical.
