【摘要】 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。更多还原

【Abstract】 The paper presents a novel 1.x lift cycle for Li-Br absorption chiller.The cycle adds an additional high pressure generator to the two-lift Li-Br absorption chiller cycle,thus operates as partial single effective and partial two-lift cycle.lt can reclaim heat source to a differential temperature as large as 25 to 30℃, and its thermal coefficient is around 0.58 at inlet and outlet temperatures of hot water equal to 85℃ and 60℃ respectively. The cycle is very suitable for air-conditioning chiller using solar energy and other low temperature heat sources, therefore,it may have significant energy conservation and environment protection consequence.更多还原
