4. Hydrofluorocarbon - Wikipedia

   en.wikipedia.org/wiki/Hydrofluorocarbon

   They are frequently used in air conditioning and as refrigerants; R-134a (1,1,1,2-tetrafluoroethane) is one of the most commonly used HFC refrigerants. In order to aid the recovery of the stratospheric ozone layer, HFCs were adopted to replace the more potent chlorofluorocarbons (CFCs), which were phased out from use by the Montreal Protocol ...

5. Thermal efficiency - Wikipedia

   en.wikipedia.org/wiki/Thermal_efficiency

   Brayton cycle: gas turbines and jet engines The Brayton cycle is the cycle used in gas turbines and jet engines. It consists of a compressor that increases pressure of the incoming air, then fuel is continuously added to the flow and burned, and the hot exhaust gasses are expanded in a turbine.

6. Coefficient of performance - Wikipedia

   en.wikipedia.org/wiki/Coefficient_of_performance

   Less work is required to move heat than for conversion into heat, and because of this, heat pumps, air conditioners and refrigeration systems can have a coefficient of performance greater than one. The COP is highly dependent on operating conditions, especially absolute temperature and relative temperature between sink and system, and is often ...
