2. Direct exchange geothermal heat pump - Wikipedia

   en.wikipedia.org/wiki/Direct_exchange_geothermal...

   A direct exchange (DX) geothermal heat pump is a type of ground source heat pump in which refrigerant circulates through copper tubing placed in the ground unlike other ground source heat pumps where refrigerant is restricted to the heat pump itself with a secondary loop in the ground filled with a mixture of water and anti-freeze.

3. 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]

4. 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 ]

5. Mechanically aided scrubber - Wikipedia

   en.wikipedia.org/wiki/Mechanically_aided_scrubber

   No internal pressure loss occurs across the scrubber, but a power loss equivalent to a pressure drop of 10.2 to 15.2 cm (4 to 6 in) of water occurs because the blower efficiency is low. Another mechanically aided scrubber, the induced-spray, consists of a whirling rotor submerged in a pool of liquid. The whirling rotor produces a fine droplet ...

6. Absorption heat pump - Wikipedia

   en.wikipedia.org/wiki/Absorption_heat_pump

   The coefficient of performance of the first type absorption heat pump is greater than 1, generally 1.5 to 2.5. [4] The heat pump is composed of the main components such as generators, condenser, evaporator, absorber and heat exchanger, as well as the suction device, shielding pump (solution pump and refrigerant pump), and other auxiliary parts.
