2. Heat pump and refrigeration cycle - Wikipedia

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

   In the generator, on heat addition, the temperature increases, and with it, the partial pressure of the refrigerant vapor is released from the strong solution. However, the generator requires a heat source, which would consume energy unless waste heat is used. In an absorption refrigerator, a suitable combination of refrigerant and absorbent is ...

3. Microturbine - Wikipedia

   en.wikipedia.org/wiki/Microturbine

   MIT's millimeter size turbine will deliver 500–700 Wh/kg (820–1,140 kJ/lb) in the near term, rising to 1,200–1,500 Wh/kg (2,000–2,400 kJ/lb) in the longer term. [ 14 ] A similar microturbine built by the Belgian Katholieke Universiteit Leuven has a rotor diameter of 20 mm and is expected to produce about 1,000 W (1.3 hp).

4. Applications of the Stirling engine - Wikipedia

   A Stirling engine eliminates the need for water anywhere in the cycle. This would have advantages for nuclear installations in dry regions. United States government labs have developed a modern Stirling engine design known as the Stirling radioisotope generator for use in space exploration. It is designed to generate electricity for deep space ...

   Often whole-house generators will be capable of powering things like the furnace, lights, refrigerator, and microwave, but you may need to upgrade if you want to be able to use your washer and ...

6. Energy conversion efficiency - Wikipedia

   en.wikipedia.org/wiki/Energy_conversion_efficiency

   However, other effectiveness measures that can exceed 1.0 are used for refrigerators, heat pumps and other devices that move heat rather than convert it. It is not called efficiency, but the coefficient of performance, or COP. It is a ratio of useful heating or cooling provided relative to the work (energy) required.

7. Thermal efficiency - Wikipedia

   en.wikipedia.org/wiki/Thermal_efficiency

   A counter flow heat exchanger is the most efficient type of heat exchanger in transferring heat energy from one circuit to the other [citation needed]. However, for a more complete picture of heat exchanger efficiency, exergetic considerations must be taken into account. Thermal efficiencies of an internal combustion engine are typically higher ...
