摘要
实验研究了水/乙二醇、水/二甘醇升温吸收式热泵性能系数COP、(火用)效率η、溶液循环比CR和温升幅度ΔT随不同热源温度t_g、热阱温度t_c及不同回流比R的变化规律。比较两种热泵的性能,水/乙二醇热泵的COP、η较高,而水/二甘醇热泵的温升较大。
The variation of the performance coefficient COP, the exergetic efficiency η, the solution circulation ratio CR and the temperature boost △T for the water/glycol and water/diglycol temperature-boost absorption heat pumps with the different heat source temperature t_g, heat sink temperature t_e and reflux ratio R is investigated experimentally. By comparison, the COP and η of the water/glycol heat pump are higher, but the temperature boost of the water/diglycol one is larger.
