本文研究了一种双热源（热和/或电）驱动的吸附式-常规蒸汽压缩式制冷机混合制冷系统的性能。双源使系统高度灵活和节能。氨制冷剂（R717）用于吸附和相关的传统制冷循环。热压缩机的模型对应于多对紧凑型吸附发生器，其异相操作，具有用于连续冷却生产和更高效率的热量和质量回收。每个发生器都基于使用活性炭-氨对的板式热交换器概念。常规蒸汽压缩机的型号是来自Frigopol的往复式压缩机。混合制冷性能主要用于制冰和空调应用（TC= 40 °C，−5 °C <TE< 20 °C）。压缩机的排气温度（热压缩机的驱动温度）在90 °C到250 °C之间变化。结果显示，在备用模式（两个循环不同时操作）下，冷却生产范围为4 kW至12 kW，在补充模式（两个循环同时操作）下，冷却生产范围为8 kW至24 kW。基于总等效热耗率输入的有效总体COP在0.24至0.76之间变化。
This paper investigates the performance of a hybrid refrigeration system that combines sorption–conventional vapour compression refrigeration machine driven by dual source (heat and/or electricity). The dual source makes the system highly flexible and energy efficient. The ammonia refrigerant (R717) is used in both adsorption and associated conventional refrigeration cycles. The model of thermal compressor corresponds to a multiple pair of compact adsorption generators operating out of phase with both heat and mass recovery for continuous cooling production and better efficiency. Each generator is based on a plate heat exchanger concept using the activated carbon–ammonia pair. The model of conventional vapour compressor is a reciprocating compressor from Frigopol. The hybrid refrigeration performances are presented mainly for ice making and air conditioning applications (TC= 40 °C, −5 °C <TE< 20 °C). The exhaust temperature of the compressor (driving temperature for thermal compressor) varies from 90 °C to 250 °C. The results show a cooling production ranging from 4 kW to 12 kW with back-up mode (both cycles not operating simultaneously) and from 8 kW to 24 kW with complementary mode (both cycles operating simultaneously). The effective overall COP based on the total equivalent heat rate input varies from 0.24 to 0.76.
