Single stage Linde-Hampson refrigerators that operate with R14-hydrocarbon mixtures can be used in place of traditional two/three stage vapour compression cascade refrigerators to provide refrigeration below–60 °C. The exergy efficiency of Linde-Hampson refrigerators can be increased by using compositions that exhibit vapour-liquid-liquid-equilibrium at low temperatures. The main aim of this work is to present the theoretical performance of a Linde-Hampson refrigerator operating with optimal R14-hydrocarbon mixtures from −120 to −60 °C. The results show that constant temperature refrigeration, however, cannot be provided above −80 °C with these mixtures. The use of nitrogen as an additional component below −100 °C is also investigated.

可以使用与R14-碳氢化合物混合物一起运行的单级Linde-Hampson冰箱来代替传统的两级/三级蒸汽压缩级联冰箱，以提供低于–60°C的制冷效果。林德-汉普森冰箱的火用效率可以通过使用在低温下表现出蒸气-液-液平衡的组合物来提高。这项工作的主要目的是介绍林德-汉普森制冷机的理论性能，该制冷机可在-120至-60°C的最佳R14-碳氢化合物混合物下运行。结果表明，对于这些混合物，不能在-80°C以上提供恒温制冷。还研究了在-100°C以下使用氮作为附加成分的情况。
