Refrigeration experiment
WebA “ton of refrigeration” is defined by the amount of heat equivalent to melting 2,000 lb (one ton) of ice in 24 hours. One ton equals 12,000 Btu/h, 200 Btu/min, or 3.5 kW. To be comparative, refrigeration equipment must have the refrigerant level (or evaporation temperature) specified [4]. View chapter Purchase book. Refrigeration refers to the process by which energy, in the form of heat, is removed from a low-temperature medium and transferred to a high-temperature medium. This work of energy transfer is traditionally driven by mechanical means, but can also be driven by heat, magnetism, electricity, laser, or other means. See more The term refrigeration denotes cooling of a space, substance or system to lower and/or maintain its temperature below the ambient one (while the removed heat is rejected at a higher temperature).
