利用空调器本身的风机从热回收器内引进新风,通过热交换回收排风的能量。采用空气焓差法对空调器引进新风前后进行制冷量、输入功率、能效比(EER)等的对比实验,并测量了换热器的热回收效率。用热回收装置引进新风后基本没有改变空调器的输入功率,相同环境条件下的制冷量增加,EER值增大,焓差热回收效率最高可达到34.12%。
Introduces into the fresh air from the heat recoverer by the fan of air-condition- er, recoveries the energy of exhaust air through heat exchange. Makes comparison experiment of refrigeration capacity, input power and EER between before and after of fresh air introduction with air enthalpy different method, and measures the recovery efficiency of heat exchanger. The input power isn't changed much when the heat recovery device is running,on the contrary the EER value becomes bigger and the enthalpy difference heat recovery efficiency reaches 34.12 %.
