2. Heat pump and refrigeration cycle - Wikipedia

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

   Thermodynamic heat pump cycles or refrigeration cycles are the conceptual and mathematical models for heat pump, air conditioning and refrigeration systems. [1] 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. [2]

3. Heat pump - Wikipedia

   en.wikipedia.org/wiki/Heat_pump

   A heat pump is a device that consumes energy (usually electricity) to transfer heat from a cold heat sink to a hot heat sink. Specifically, the heat pump transfers thermal energy using a refrigeration cycle , cooling the cool space and warming the warm space. [ 1 ]

4. Cooling load temperature difference calculation method

   en.wikipedia.org/wiki/Cooling_load_temperature...

   The CLF is the cooling load at a given time compared to the heat gain from earlier in the day. [1] [5] The SC, or shading coefficient, is used widely in the evaluation of heat gain through glass and windows. [1] [5] Finally, the SCL, or solar cooling load factor, accounts for the variables associated with solar heat load.

5. Ground source heat pump - Wikipedia

   These heat pumps are also preferred for pool heating. Heat pumps typically only heat water to about 55 °C (131 °F) efficiently, whereas boilers typically operate at 65–95 °C (149–203 °F) [citation needed]. The size of radiators designed for the higher temperatures achieved by boilers may be too small for use with heat pumps, requiring ...

6. Clausius theorem - Wikipedia

   en.wikipedia.org/wiki/Clausius_theorem

   In the heat engine model with two thermal reservoirs (hot and cold reservoirs), the limit of the efficiency of any heat engine =, where and are work done by the heat engine and heat transferred from the hot thermal reservoir to the engine, respectively, can be derived by the first law of thermodynamics (i.e., the law of conservation of energy ...

7. 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 ...
