双缸滚动转子式压缩机采暖热泵低温制热性能
Heating performance of space heating heat pump based on dual-cylinder rotary compressor in ultra-low temperature
摘要
Abstract
The heating performance of space heating heat pump (SHHP) with dual-cylinder rotary compressor was tested at low ambient temperature (Tod) in the range of-30—0℃, and water outlet temperature (Two) in the range of 41—50℃. The results show that ambient temperature has great influence on its discharge temperature and evaporating temperature, but little on condensing temperature; hot water outlet temperature has great influence on its condensing temperature, and little influence on its discharge temperature and evaporating temperature. With the decrease of ambient temperature, the heat capacity of SHHP decreases sharply, when Two=41℃, Tod decreases from 0℃to-30℃, and the heat capacity decreases by 62.16%. With the increase of outlet temperature, the heat capacity of SHHP decreases slowly, when Tod=0℃, Two rises from 41℃to 45℃, the heat capacity decreases by only 5.61%. The influence of ambient temperature on COPh value is also obvious, when Two = 41℃, Tod decreases from 0℃ to-30℃, COPh decreases from 2.94 to 1.38, a drop of 53.06%. The SHHP with dual-cylinder rotary compressor has good practical value to be applied in low temperature condition of-30—0℃.关键词
