摘　　要：依据GB/T 21087—2007《空气-空气能量回收装置》,对影响热回收装置节能性能的关键因素进行了试验研究,分析了风量、输入功率、有效换气率对交换效率的影响。结果表明,对于同一热回收装置,交换效率随风量及有效换气率的增大而降低;对于带风机的热回收装置,新风侧电动机的输入功率对制冷工况的交换效率为负影响,对制热工况的交换效率为正影响。According to the national standard GB/T 21087--2007 Air-to-air energy recovery equipment, experimentally studies the key factors influencing the energy efficiency, and analyses the influences of the air flow rate, power input and net outdoor air exchange rate on the exchange efficiency. The result indicates that for one energy recovery device, the exchange efficiency goes down with the raise of air flow rate and net outdoor air exchange rate, and for the energy recovery device with fan, the power input of the motor of the outdoor air fan has an negative influence on the exchange efficiency in cooling processes while positive influence in heating processes.
