地热用离心式电热泵和燃气吸收式热泵比较

Performance and economy comparison between centrifugal electric heat pump and gas absorption heat pump in geothermal heating field

比较了离心式电热泵和燃气吸收式热泵的原理和各自的优缺点,结合天津某供暖实际案例,对选取地热与热泵联合供暖系统选取离心式电热泵和燃气吸收式热泵这两种方案的投资和运行费用进行对比分析,得出在具体情况下热泵形式的选取方案。

Introduces the situation of geothermal energy and its advantages in the field of heating.Introduces the theory and advantage of centrifugal electric heat pump and gas lithium bromide absorptionheat pump.Combined with a practical heating case in Tianjin,this paper introduces the combined heating system of geothermal and heat pump,and introduces two schemes,the investment and operation cost of two heat pump systems are compared and analyzed.In the end,it points outwhich kind of heat pump should be used in certain situation.
