摘要
吸收式制冷的优势在于可用低势热源驱动并以环保无公害流体作为工作介质，缺点是性能系数（ＣＯＰ）较低。研究表明，非共沸混合制冷剂（ＮＡＲＭ）在用于蒸汽压缩制冷循环中时可表现出较高ＣＯＰ。本文中提出了一个使用ＮＡＲＭ作制冷剂的吸收制冷循环，并对其不同工况进行了计算和分析。结果表明，新循环的ＣＯＰ及制冷量均要高于传统循环。
Absorption refrigeration can use low thermal potential energy as its power and environment friendly fluids as its working substance. The main defect of absorption refrigeration is its lower coefficient of performance(COP).On the other hand, studies show that non azeotropic refrigerant mixture (NARM) has a higher COP when it is used in vapor compression refrigeration cycle. In this paper, a new absorption refrigeration cycle was proposed which uses NARM as refrigerant so as to ger a higher COP of the cycle. The characteristics of the cycle at different working conditions were calculated and analyzed. The results show that both COP and refrigeration capacity were higher than those of traditional cycle.
