本文设计并建立了双工质混合制冷系统，并将其与林德-汉普森制冷(LHR)循环和三级自动复叠制冷(ACR)循环相结合。用R1234yf/R32作为LHR和R170/R14/R50作为ACR的低GWP沸腾混合物，对耦合体系的热力学性能进行了实验研究。实验结果表明，当环境平均温度为24.18℃时，样机达到−120℃的空载温度水平约需0.5h，达到−146.97℃的空载温度水平约需4h，相当接近稳态。相应的制冷量为182.94 W，性能系数COP为0.121，相对卡诺效率为16.0%。冷凝蒸发器-I(CE-I)、CE-II和CE-III的热液出口温度分别为−49.04℃、−87.12℃和−113.20℃。此外，随着环境温度的升高，排气压力、蒸发温度和制冷量略有增加，而吸气压力和COP基本不变。LHR-ACR系统作为一种新的冷却方法在能源梯级利用领域(如多温度低温保存和天然气液化)中产生从−40°C到−150°C的多种温度，显示了良好的前景。
In this study, a dual mixed-refrigerants refrigeration system coupled with a Linde-Hampson refrigeration (LHR) cycle and a three-stage auto-cascade refrigeration (ACR) cycle was designed and built. The thermodynamic performance of the coupled system was experimentally investigated using low GWP zeotropic mixtures of R1234yf/R32 for the LHR and R170/R14/R50 for the ACR. The experimental results show that when the average ambient temperature was 24.18 °C, it took about 0.5 h for the prototype to reach a no-load temperature level of −120 °C, and 4 h to −146.97 °C, which was quite close to steady state. The corresponding cooling capacity, coefficient of performance (COP) and relative Carnot efficiency were 182.94 W, 0.121 and 16.0%, respectively. The hot fluid outlet temperatures in the condensation evaporator-I (CE-I), CE-II and CE-III were −49.04 °C, −87.12 °C and −113.20 °C, respectively. In addition, the discharge pressure, evaporation temperature and cooling capacity increased slightly with increasing ambient temperature, while the suction pressure and COP remained nearly constant. The LHR-ACR system manifests a promising perspective as a new cooling approach to produce multi-temperatures ranging from −40 °C to −150 °C in the energy cascade utilization fields, such as the multi-temperature cryopreservation and gas liquefaction.
