2. Heat pump - Wikipedia

   en.wikipedia.org/wiki/Heat_pump

   Specifically, the heat pump transfers thermal energy using a heat pump and refrigeration cycle, cooling the cool space and warming the warm space. [1] In winter a heat pump can move heat from the cool outdoors to warm a house; the pump may also be designed to move heat from the house to the warmer outdoors in summer.

3. High-voltage interface relay - Wikipedia

   en.wikipedia.org/wiki/High-voltage_interface_relay

   High voltage interface relays, a.k.a., interface relays: [1] [2] or coupling relays or insulating interfaces [3] [4] is a special class of electrical relays designed to provide informational and electrical compatibility between functional components isolated from each other and not allowing for a direct connection due to a high difference of potentials.

4. Forced-air - Wikipedia

   en.wikipedia.org/wiki/Forced-air

   A heat exchanger (hydronic coil) is placed in the air handler similar to the refrigerant coil in a Heat Pump system or a Central AC. Copper is often specified in supply and return manifolds and in tube coils. Heated water is pumped through the heat exchanger then back to the boiler to be reheated

5. Centrifugal fan - Wikipedia

   en.wikipedia.org/wiki/Centrifugal_fan

   Centrifugal fans often contain a ducted housing to direct outgoing air in a specific direction or across a heat sink; such a fan is also called a blower, blower fan, or squirrel-cage fan (because it looks like a hamster wheel). Tiny ones used in computers are sometimes called biscuit blowers. These fans move air from the rotating inlet of the ...

6. Thermoacoustic heat engine - Wikipedia

   en.wikipedia.org/wiki/Thermoacoustic_heat_engine

   Thermoacoustic engines (sometimes called "TA engines") are thermoacoustic devices which use high-amplitude sound waves to pump heat from one place to another (this requires work, which is provided by the loudspeaker) or use a heat difference to produce work in the form of sound waves (these waves can then be converted into electrical current ...

7. Goodman Global - Wikipedia

   en.wikipedia.org/wiki/Goodman_Global

   In October 2016, operations at the new facility ramped up and the first Goodman air conditioner and gas furnace units came off the line. [12] In 2017, the construction of the huge facility concluded to consolidate Goodman’s HVAC manufacturing, engineering, logistics, and customer support under one, very large 4.1 million square foot roof. [13]

8. Air-start system - Wikipedia

   en.wikipedia.org/wiki/Air-start_system

   Compared to a gasoline (petrol) engine, a diesel engine has a very high compression ratio, an essential design feature, as it is the heat of compression that ignites the fuel. An electric starter with sufficient power to turn a large diesel engine would itself be so large as to be impractical so there is a need for an alternative system.

9. Motor–generator - Wikipedia

   en.wikipedia.org/wiki/Motor–generator

   An Alexanderson alternator is a motor-driven, high-frequency alternator which provides radio frequency power. In the early days of radio communication, the high frequency carrier wave had to be produced mechanically using an alternator with many poles driven at high speeds. Alexanderson alternators produced RF up to 600 kHz, with large units ...
