When the hot air, the ambient air and the refrigerating temperature are 230 °C, 30 °C and −5 °C, respectively, the average refrigerating capacity is 2.2 kW in the sorption process.
Performance parameters like, discharge temperature, volumetric refrigerating capacity and required mass flow of refrigerant were found to be lower with R290 when compared to R22.
When storing food, none of the participants were aware of the recommended time (within 2 hours of cooking) and temperature for refrigerating or freezing cooked food.
It is also found that the refrigerating compartment possesses the worst temperature non-uniformity.
However, it is found that the temperature variation for freezer and refrigerating compartment are in phase with each other while the temperature variation in vegetable compartment is roughly out-of-phase with the other two compartments.
For temperature-dependent studies, a refrigerating circulator (Fisher Scientific Isotemp 1016D) circulated water at 8, 25, and 40 °C to a custom-made bath in contact with a sample bath in the flow system.
The SCP and volume refrigerating density of this refrigerator are about 1.8 times and 1.5 times that of the maximum of the former test results by other researchers.
Different from the conventional single-stage ejector refrigeration system, this two-stage system is finally found to be capable of supplying more refrigerating effect in situations where the condensation temperature is lower than 21.7 °C.
Taking advantage of the refrigerating effect in the expansion at an appropriate temperature, a fraction of high-pressure natural gas transported by pipelines could be liquefied in a city gate station through a well-organized pressure reducing process without consuming any extra energy.
The condenser has a refrigerating system (TURBO) that thermostatically controls the working temperature, and a disposable respiratory system (DECCS) that consists of a mouthpiece connected to a one-way aspiration valve and (through a tube with a special stopper) an EBC collection test tube at the end.
