Determine refrigeration or power cycle
WebAn experimental study of a typical small capacity food freezer has been carried out to determine the refrigeration cycle. The temperatures, pressures and electric power of the plant were measured and some thermocouples were also positioned inside the hermetic compressor unit to improve the description of the refrigeration cycle. The cycle was WebTon of Refrigeration (TR) is equal to the rate of energy removal need to freeze one ton of water in one day. One TR is defined at 12,000 Btu/hr, or 3.517 kW. A refrigeration system’s coefficient of performance (CoP) is one way to determine the overall efficiency of a system.
