| 摘 要： | 为解决寒冷地区冬季空气源热泵运行效率、新风机冻损等运行问题,保证冬季室内良好的空气品质,设计了在冬季将排风引入热泵蒸发器,通过热交换回收排风的能量,并利用热泵冷凝器加热引入室内新风的热泵热回收新风机。采用空气焓差法对该机组在利用排风及排风混室外空气2种运行工况下的制热量、输入功率、热泵能效比(COP)、热回收效率的对比实验。用热泵热回收新风机引进新风后基本没有改变机组输入功率,相同环境条件下的制热量增加,COP值增大,焓差热回收效率最高可达到51.4%。新风机和热泵相结合,利用排风余热提高热泵蒸发器工作温度,改善了热泵和新风机在北方寒冷地区冬季的运行性能。

| Abstract: | To solve the problems of air source heat pump efficiency and the fresh air unit freezing in winter of the cold regions,to ensure the well indoor air quality. Designed the recovery fresh air heat pump units,that inducted exhaust into evaporator of heat pump,recovered the energy of exhaust by heat exchange,and heated fresh air used condenser of heat pump. Used the enthalpy difference method experiment. Measured the heat quantity ,the electricity power,the coefficient of performance (COP)and the recovery effic... |
