2. Trane - Wikipedia

   en.wikipedia.org/wiki/Trane

   By 1916, the Trane's were no longer in the plumbing business, but instead focused their attention on manufacturing heating products. Reuben's invention of the convector radiator in 1923, which replaced the heavy, bulky, cast-iron radiators that prevailed at the time, was a major success. Trane's first air conditioning unit was developed in 1931 ...

3. 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.

   In 1913, James and Reuben incorporated The Trane Company. By 1916, the Tranes focused their attention on manufacturing heating products. Reuben's invention of the convector radiator in 1923, which replaced the heavy, bulky, cast-iron radiators that prevailed at the time, was a major success.

5. Economizer - Wikipedia

   en.wikipedia.org/wiki/Economizer

   An internal heat exchanger is simply a heat exchanger that uses the cold gas leaving the evaporator coil to cool the high-pressure liquid that is headed into the beginning of the evaporator coil via an expansion device. The gas is used to chill a chamber that normally has a series of pipes for the liquid running through it.

6. Thermal expansion valve - Wikipedia

   en.wikipedia.org/wiki/Thermal_expansion_valve

   A thermal expansion valve is a key element to a heat pump; this is the cycle that makes air conditioning, or air cooling, possible. A basic refrigeration cycle consists of four major elements: a compressor, a condenser, a metering device and an evaporator. As a refrigerant passes through a circuit containing these four elements, air ...

7. Heat pump - Wikipedia

   en.wikipedia.org/wiki/Heat_pump

   In heating mode this heat is used to heat the building using the internal heat exchanger, and in cooling mode this heat is rejected via the external heat exchanger. The condensed, liquid refrigerant, in the thermodynamic state known as a saturated liquid , is next routed through an expansion valve where it undergoes an abrupt reduction in pressure.
