寒冷地区空气源热泵实验研究

Research on The Air-source Heat Pump Applications in The Cold and Serious Cold Regions

研制了以回收排风热量为热源来预热室外新风的空调实验系统,解决了在寒冷地区冬季空气源热泵不能正常运行和新风机组冻裂的问题,为实际工程应用奠定了技术基础。研究结果表明,该系统各项技术指标稳定,满足建筑物冬季供热的负荷要求;测得COP值在4.10以上,热回收效率最高可达85%,具有良好的节能性和经济性。

An air condition experimental system is studied, with the recycled exhaust heat to heat fresh air, to solve the air-source heat pump not run and the new issue of wind frost ＇crack unit. The work builds an engineering basis. The experimental results show that the indexes meet the needs of load for heating in winter. The COP in the value of more than 4.10, and the heat recovery efficiency up to 85%. The system is energy saving and economical.
