2. Heat transfer enhancement - Wikipedia

   en.wikipedia.org/wiki/Heat_transfer_enhancement

   Increased heat transfer due to the secondary flow is not significant in turbulent state constituting less than 10% for /. Furthermore, augmentation created by the use of helically coiled tubes due to the secondary flow is usually employed only for situations where the flow is in the laminar state.

3. Tubular Exchanger Manufacturers Association - Wikipedia

   en.wikipedia.org/wiki/Tubular_Exchanger...

   The member companies of TEMA must demonstrate high quality exchanger fabrication standards, and possess in-house engineering capability for mechanical and thermal design of shell and tube type heat exchangers. Companies may fabricate other equipment in addition to heat exchangers. The current member companies of TEMA (in alphabetical order) are:

4. Internally grooved copper tube - Wikipedia

   en.wikipedia.org/wiki/Internally_grooved_copper_tube

   In a design study of functionally equivalent 5 kW HVAC heat exchangers, tube materials in the coils weighed 3.09 kg for 9.52 mm diameter tube, 2.12 kg for 7 mm diameter tube, and 1.67 kg for 5 mm diameter tube. Tube weight was reduced by 31% when copper tube diameters were downsized from 3/8 inch to 7 mm. Tube weight was reduced by 46% when ...

5. Shell-and-tube heat exchanger - Wikipedia

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

   In shell-and-tube heat exchangers there is a potential for a tube to rupture and for high pressure (HP) fluid to enter and over-pressurise the low pressure (LP) side of the heat exchanger. [8] The usual configuration of exchangers is for the HP fluid to be in the tubes and for LP water, cooling or heating media to be on the shell side.

6. 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]

7. Copper in heat exchangers - Wikipedia

   en.wikipedia.org/wiki/Copper_in_heat_exchangers

   These heat exchangers are used in air conditioning and refrigeration systems, industrial and central heating and cooling systems, radiators, hot water tanks, and under-floor heating systems. Copper-based heat exchangers can be manufactured with copper tube/aluminum fin, cupro-nickel, or all-copper constructions.

8. Pipe (fluid conveyance) - Wikipedia

   en.wikipedia.org/wiki/Pipe_(fluid_conveyance)

   Steel pipe is still used in many homes and businesses to convey natural gas or propane fuel, and is a popular choice in fire sprinkler systems due to its high heat resistance. In commercial buildings, steel pipe is used to convey heating or cooling water to heat exchangers, air handlers, variable air volume (VAV) devices, or other HVAC equipment.
