2. Quantum heat engines and refrigerators - Wikipedia

   en.wikipedia.org/wiki/Quantum_heat_engines_and...

   The relation between the quantum amplifier and the Carnot efficiency was first pointed out by Scovil and Schultz-DuBois: [1] Reversing the operation driving heat from the cold bath to the hot bath by consuming power constitutes a refrigerator. The efficiency of the refrigerator defined as the coefficient of performance (COP) for the reversed ...

3. Minimum energy performance standard - Wikipedia

   en.wikipedia.org/wiki/Minimum_energy_performance...

   A minimum energy performance standard (MEPS) is a specification, containing a number of performance requirements for an energy-using device, that effectively limits the maximum amount of energy that may be consumed by a product in performing a specified task. An MEPS is usually made mandatory by a government's energy efficiency body.

4. Coefficient of performance - Wikipedia

   en.wikipedia.org/wiki/Coefficient_of_performance

   The heat pump itself can be improved by increasing the size of the internal heat exchangers, which in turn increases the efficiency (and the cost) relative to the power of the compressor, and also by reducing the system's internal temperature gap over the compressor. Obviously, this latter measure makes some heat pumps unsuitable to produce ...

5. Solar-powered refrigerator - Wikipedia

   en.wikipedia.org/wiki/Solar-powered_refrigerator

   A solar-powered refrigerator is a refrigerator which runs on energy directly provided by sun, and may include photovoltaic or solar thermal energy. Solar-powered refrigerators are able to keep perishable goods such as meat and dairy cool in hot climates and are used to keep much-needed vaccines at their appropriate temperature to avoid spoilage.
