Cooling capacity is the measure of a cooling system's ability to remove heat. [ 1] It is equivalent to the heat supplied to the evaporator/boiler part of the refrigeration cycle and may be called the "rate of refrigeration" or "refrigeration capacity". As the target temperature of the refrigerator approaches ambient temperature, without ...
Coefficient of performance. The coefficient of performance or COP (sometimes CP or CoP) of a heat pump, refrigerator or air conditioning system is a ratio of useful heating or cooling provided to work (energy) required. [ 1][ 2] Higher COPs equate to higher efficiency, lower energy (power) consumption and thus lower operating costs.
The gas-cooling throttling process is commonly exploited in refrigeration processes such as liquefiers in air separation industrial process. [7] [8] In hydraulics, the warming effect from Joule–Thomson throttling can be used to find internally leaking valves as these will produce heat which can be detected by thermocouple or thermal-imaging ...
2,593.90 ft⋅lbf/s. A ton of refrigeration ( TR or TOR ), also called a refrigeration ton ( RT ), is a unit of power used in some countries (especially in North America) to describe the heat-extraction capacity of refrigeration and air conditioning equipment. It was originally defined as the rate of heat transfer that results in the freezing ...
In thermodynamics, the enthalpy of vaporization (symbol ∆Hvap ), also known as the ( latent) heat of vaporization or heat of evaporation, is the amount of energy ( enthalpy) that must be added to a liquid substance to transform a quantity of that substance into a gas. The enthalpy of vaporization is a function of the pressure and temperature ...
Vapour-compression refrigeration or vapor-compression refrigeration system ( VCRS ), [ 1] in which the refrigerant undergoes phase changes, is one of the many refrigeration cycles and is the most widely used method for air conditioning of buildings and automobiles. It is also used in domestic and commercial refrigerators, large-scale warehouses ...
Thermodynamic heat pump cycles or refrigeration cycles are the conceptual and mathematical models for heat pump, air conditioning and refrigeration systems. A heat pump is a mechanical system that transmits heat from one location (the "source") at a certain temperature to another location (the "sink" or "heat sink") at a higher temperature. [ 1]
In thermodynamics, the thermal efficiency ( ) is a dimensionless performance measure of a device that uses thermal energy, such as an internal combustion engine, steam turbine, steam engine, boiler, furnace, refrigerator, ACs etc. For a heat engine, thermal efficiency is the ratio of the net work output to the heat input; in the case of a heat ...
