摘要
采用试验方法,针对夏季工况,对空气-土壤源热泵机组分别在单纯空气源热泵运行模式、单纯土壤源热泵运行模式、空气-土壤源热泵运行模式下的制冷性能系数、能效比进行了实测比较。空气-土壤源热泵运行模式下的制冷性能系数、能效比较高,有利于改善土壤热平衡。
The refrigeration coefficient of performance and energy efficiency ratio of airsoil source heat pump unit in single air source heat pump mode, soil source heat pump mode and air-soil source heat pump mode respectively are compared and measured by experimental method under summer condition. The higher refrigeration coefficient of performance and energy efficiency ratio are achieved by air-soil source heat pump operation mode which is conducive to improving soil thermal equilibrium.
