Compression-injection hybrid refrigeration cycles in household refrigerators

Three different connection forms for refrigerator compression-injection hybrid refrigeration cycles were presented in this paper. The pressure at the connector of the three ejectors and the power consumption were measured, and the performances of the three different connection forms for compressor-jet mixing of the refrigeration cycle were compared. Results show that for the compression-injection cross-regenerative hybrid refrigeration cycle system, loss of heat in the throttle processing was decreased effectively by an ejector. Energy consumption of the refrigerator prototype was 0.655 kWh/day, indicating an energy consumption reduction of 7.75%.
