2. Coefficient of performance - Wikipedia

   en.wikipedia.org/wiki/Coefficient_of_performance

   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.

3. Cooling capacity - Wikipedia

   en.wikipedia.org/wiki/Cooling_capacity

   Cooling capacity. 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 ...

4. Seasonal energy efficiency ratio - Wikipedia

   en.wikipedia.org/wiki/Seasonal_energy_efficiency...

   The energy efficiency ratio (EER) of a particular cooling device is the ratio of output cooling energy (in BTUs) to input electrical energy (in watt-hours) at a given operating point. EER is generally calculated using a 95 °F (35 °C) outside temperature and an inside (actually return-air) temperature of 80 °F (27 °C) and 50% relative humidity.

   In many American kitchens, the refrigerator is one of the most essential appliances. Here are four simple strategies you can use right now to minimize the energy cost, replacement cost and food ...

6. Heat pump and refrigeration cycle - Wikipedia

   en.wikipedia.org/wiki/Heat_pump_and...

   e. 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]

7. Ton of refrigeration - Wikipedia

   en.wikipedia.org/wiki/Ton_of_refrigeration

   12,000.00 Btu IT /h. 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 ...
