太阳能空气能直膨变频翅片热泵热水器结霜的实验研究
摘要:摘要本文在带有太阳能模拟器的焓差实验室中研究了环温、辐照及压缩机频率对太阳能/空气能直膨变频翅片热泵热水器结霜及性能的影响。结果表明,水温较低时,热泵结霜程度随水温升高而加重,当水温升到一定值后,结霜随水温升高而减轻,直至完全消失。系统瞬时COP随水温升高而减小。当环温升高和辐照增强时,系统结霜程度减轻,COP增大。当压缩机频率降低时,系统结霜程度减轻,平均COP增大。
Abstract::In this study, the influence of ambient temperature, solar radiation, and compressor frequency on the frost characteristics and heating performance of a solar/air source direct expansion variable frequency finned heat pump was investigated in an enthalpy difference lab with a solar simulator. Results show that, at the beginning, the frost accumulates with the rising of the water temperature, after the water temperature reaches a certain value, the frost gradually dissolves with the rising of the water temperature until totally disappears. The instant COP of the heat pump decreases with the rising of water temperature. When the ambient temperature or solar radiation rises, the frost becomes less serious and COP increases. When the compressor frequency decreases, the frost becomes less serious and the average COP increases.
