2. Rheem Manufacturing Company - Wikipedia

   en.wikipedia.org/wiki/Rheem_Manufacturing_Company

   Rheem Manufacturing Company is a privately held manufacturer who produces residential and commercial water heaters, boilers, heating, ventilating and air conditioning (HVAC) equipment. The company also produces and sells products under the Ruud brand name. Rheem is headquartered in Atlanta, Georgia, and is an independent subsidiary of Paloma ...

3. Reversing valve - Wikipedia

   en.wikipedia.org/wiki/Reversing_valve

   A reversing valve removed from an HVAC heat pump for replacement. A reversing valve is a type of valve and is a component in a heat pump, that changes the direction of refrigerant flow. By reversing the flow of refrigerant, the heat pump refrigeration cycle is changed from cooling to heating or vice versa. This allows a residence or facility to ...

4. Central heating - Wikipedia

   en.wikipedia.org/wiki/Central_heating

   A central heating system has a furnace that converts fuel or electricity to heat through processes. The heat is circulated through the building either by fans forcing heated air through ducts, circulation of low-pressure steam to radiators in each heated room, or pumps that circulate hot water through room radiators.

5. Forced-air - Wikipedia

   en.wikipedia.org/wiki/Forced-air

   Heat is produced via combustion of fuel. A heat exchanger keeps the combustion byproducts from entering the air stream. A ribbon style (long with holes), inshot (torch-like), or oil type burner is located in the heat exchanger. Ignition is provided by an electric spark, standing pilot, or hot surface igniter.

6. Furnace (central heating) - Wikipedia

   en.wikipedia.org/wiki/Furnace_(central_heating)

   A condensing gas furnace includes a sealed combustion area, combustion draft inducer and a secondary heat exchanger. The primary gain in efficiency for a condensing gas furnace, as compared to a mid-efficiency forced-air or forced-draft furnace, is the capture of latent heat from the exhaust gases in the secondary heat exchanger.

7. Recuperator - Wikipedia

   en.wikipedia.org/wiki/Recuperator

   In many types of processes, combustion is used to generate heat, and the recuperator serves to recuperate, or reclaim this heat, in order to reuse or recycle it. The term recuperator refers as well to liquid-liquid counterflow heat exchangers used for heat recovery in the chemical and refinery industries and in closed processes such as ammonia-water or LiBr-water absorption refrigeration cycle.

8. Regenerative heat exchanger - Wikipedia

   en.wikipedia.org/wiki/Regenerative_heat_exchanger

   A regenerative heat exchanger, or more commonly a regenerator, is a type of heat exchanger where heat from the hot fluid is intermittently stored in a thermal storage medium before it is transferred to the cold fluid. To accomplish this the hot fluid is brought into contact with the heat storage medium, then the fluid is displaced with the cold ...

9. 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 ...
