2. Recuperator - Wikipedia

   en.wikipedia.org/wiki/Recuperator

   Types of recuperator, or cross plate heat exchanger. A recuperator is a special purpose counter-flow energy recovery heat exchanger positioned within the supply and exhaust air streams of an air handling system, or in the exhaust gases of an industrial process, in order to recover the waste heat. Generally, they are used to extract heat from ...

3. Heat exchanger - Wikipedia

   en.wikipedia.org/wiki/Heat_exchanger

   Tubular heat exchanger Partial view into inlet plenum of shell and tube heat exchanger of a refrigerant based chiller for providing air-conditioning to a building. A heat exchanger is a system used to transfer heat between a source and a working fluid. Heat exchangers are used in both cooling and heating processes. [1]

4. Shell-and-tube heat exchanger - Wikipedia

   en.wikipedia.org/wiki/Shell-and-tube_heat_exchanger

   Fluid flow simulation for a shell-and-tube style exchanger; The shell inlet is at the top rear and outlet in the foreground at the bottom Shell and tube heat exchanger. A shell-and-tube heat exchanger is a class of heat exchanger designs. [1] [2] It is the most common type of heat exchanger in oil refineries and other large chemical processes ...

5. Baffle (heat transfer) - Wikipedia

   en.wikipedia.org/wiki/Baffle_(heat_transfer)

   It is used in some household stoves [1] and in some industrial process vessels (tanks), such as shell and tube heat exchangers, chemical reactors, and static mixers. Baffles are an integral part of the shell and tube heat exchanger design. A baffle is designed to support tube bundles and direct the flow of fluids for maximum efficiency.

6. Water heat recycling - Wikipedia

   en.wikipedia.org/wiki/Water_heat_recycling

   Installation of a double-walled copper-on-copper heat exchanger in a vertical section of the master drain line in a Canadian home (2007) Water heat recycling (also known as drain water heat recovery, waste water heat recovery, greywater heat recovery, [citation needed] or sometimes shower water heat recovery [citation needed]) is the use of a heat exchanger to recover energy and reuse heat ...

7. Plate heat exchanger - Wikipedia

   en.wikipedia.org/wiki/Plate_heat_exchanger

   A plate heat exchanger is a type of heat exchanger that uses metal plates to transfer heat between two fluids.This has a major advantage over a conventional heat exchanger in that the fluids are exposed to a much larger surface area because the fluids are spread out over the plates.

8. Heat recovery ventilation - Wikipedia

   en.wikipedia.org/wiki/Heat_recovery_ventilation

   Diagramatic operation of a thermal wheel Ljungström Air Preheater by Swedish engineer Fredrik Ljungström (1875–1964). A thermal wheel, also known as a rotary heat exchanger, or rotary air-to-air enthalpy wheel, energy recovery wheel, or heat recovery wheel, is a type of energy recovery heat exchanger positioned within the supply and exhaust air streams of air-handling units or rooftop ...

9. Tankless water heating - Wikipedia

   en.wikipedia.org/wiki/Tankless_water_heating

   A tankless water heater only heats water on demand, so idle water in the piping starts at room temperature. Thus, there may be a more apparent "flow delay" for hot water to reach a distant faucet (in non-point-of-use systems). Many models sold in the UK have introduced a small heat store within the combination boiler to address this issue.
