为了优化吸收式制冷循环性能，对一种蒸发吸收热交换式-吸收式制冷循环进行了热力学分析。选择高压冷凝温度T8和蒸发吸收热交换器出口温差?![]() ![]() TEAX为自变量，研究了?![]() ![]() TEAX与中压节流温度T12的对应关系，分析了T8对?TEAX取值范围的影响；考察了循环中溶液放气范围的变化，分析了?![]() ![]() TEAX对制冷剂流量、循环制冷量和循环利用效率的影响。结果表明: 当高温发生器出口温度和?![]() ![]() TEAX一定时，存在最佳T8使循环利用效率取极大值；最佳T8随?![]() ![]() TEAX增加而逐渐增大，对应的循环利用效率极大值逐渐减小。 |

In order to optimize the performance of absorption refrigeration cycle, a thermodynamic analysis is carried out on an evaporative absorption heat exchange-absorption refrigeration cycle. The high pressure condenser temperature T8 and the temperature difference ?![]() ![]() TEAX in the outlet of evaporative absorption heat exchanger were chosen as independent variables. The corresponding relationship between ?![]() ![]() TEAX and medium pressure throttling temperature T12 is studied, and the influence of T8 on the value range of ?![]() ![]() TEAX is analyzed. The change of solution degassing range in the cycle was investigated, and the influence of ?![]() ![]() TEAX on refrigerant flow, cycle cooling capacity QE and η was analyzed. When the outlet temperature of the high temperature generator and ?![]() ![]() TEAX are constant, there is an optimal T8 to maximize the cycle η. With the increase of ?![]() ![]() TEAX, the optimal T8 increases gradually, and the corresponding η maximum decreases gradually. |
