文中介绍了一种新型1.x级溴化锂吸收式制冷机循环。该新型循环在原有两级澳化锂吸收式制冷循环基础上增加了一个附加高压发生器,使部分流体按单效循环工作,同时可将热源进出口温差加大到25—30℃左右,在热水进出口温度为85℃和60℃时,热力系数COP则能达到0.58左右。该循环非常适合于利用太阳能等低势热能制冷,能够产生显著的节能和环保效果。
This paper introduces a new type of 1.x lithium bromide absorption chiller cycle. The new cycle adds two additional high-pressure generators based on the original two-stage Australian lithium absorption refrigeration cycle, allowing part of the fluids to circulate according to the single effect. At the same time, the temperature difference between the inlet and outlet of the heat source can be increased to about 25-30 ° C. Hot water inlet and outlet temperatures of 85 ℃ and 60 ℃, the thermal coefficient of COP can reach about 0.58. This cycle is ideal for cooling with low-temperature thermal energy such as solar energy, resulting in significant energy savings and environmental benefits.
