空调系统中全热换热器的实验研究

Experimental Research on Heat Recovery Ventilator of Air Conditioning System

通过在空调系统中增设全热换热器,利用排风与新风进行热交换来实现热回收,能够显著减少空调系统的能耗。针对全热换热器,确定热湿交换性能实验方案,并进行了相应的实验测试。实验研究结果表明:全热换热器联合空调系统运行导致温度效率和焓效率都低于其独立运行时的温度效率和焓效率,因此空调系统与全热换热器的联合运行必须进行合理匹配。此研究为全热换热器在空调系统中的推广应用提供参考。

By adding an heat recovery ventilator in the air-conditioning system, the heat can be recycled through heat exchangebetween exhaust air and fresh air and the energy consumed by air conditioning system can be significantly reduced. In this paper, aexperimental program was determined to test the heat and moisture exchange performance of heat recovery ventilator and thecorresponding experimental test was carried out. The results show that the operation of heat recovery ventilator combined withair-conditioning system resulted in lower temperature efficiency and enthalpy efficiency than its independent operation. Therefore,the combined operation of the air conditioning system and the heat recovery ventilator must be reasonably matched. The research inthis paper provides a reference for the popularization and application of heat recovery ventilator in air conditioning system.
