  2. Thermoelectric cooling - Wikipedia

    en.wikipedia.org/wiki/Thermoelectric_cooling

    Thermoelectric cooling uses the Peltier effect to create a heat flux at the junction of two different types of materials. A Peltier cooler, heater, or thermoelectric heat pump is a solid-state active heat pump which transfers heat from one side of the device to the other, with consumption of electrical energy, depending on the direction of the current.

  3. Plate heat exchanger - Wikipedia

    en.wikipedia.org/wiki/Plate_heat_exchanger

    The plate heat exchanger (PHE) is a specialized design well suited to transferring heat between medium- and low-pressure fluids. Welded, semi-welded and brazed heat exchangers are used for heat exchange between high-pressure fluids or where a more compact product is required. In place of a pipe passing through a chamber, there are instead two ...

  4. Shell-and-tube heat exchanger - Wikipedia

    en.wikipedia.org/wiki/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, and is suited for higher-pressure applications. As its name implies, this type of heat exchanger consists of a shell (a large pressure vessel) with a bundle of tubes ...

  5. Electric heating - Wikipedia

    en.wikipedia.org/wiki/Electric_heating

    Electric heating. This radiant heater uses tungsten halogen lamps. Electric heating is a process in which electrical energy is converted directly to heat energy. Common applications include space heating, cooking, water heating and industrial processes. An electric heater is an electrical device that converts an electric current into heat. [1]

  6. Free cooling - Wikipedia

    en.wikipedia.org/wiki/Free_cooling

    Free cooling. Free cooling is an economical method of using low external air temperatures to assist in chilling water, which can then be used for industrial processes, or air conditioning systems. The chilled water can either be used immediately or be stored for the short- or long-term. When outdoor temperatures are lower relative to indoor ...

  7. Chiller - Wikipedia

    en.wikipedia.org/wiki/Chiller

    A chiller is a machine that removes heat from a liquid coolant via a vapor-compression, adsorption refrigeration, or absorption refrigeration cycles. This liquid can then be circulated through a heat exchanger to cool equipment, or another process stream (such as air or process water). As a necessary by-product, refrigeration creates waste heat ...

    Yet Abreu’s adjusted OPS was 3 – yes, three – and he’d racked up minus-1.6 Wins Above Replacement in just 120 plate appearances. Singleton, at the least, has an elite chase rate of 22.5% ...

  9. Heat recovery ventilation - Wikipedia

    en.wikipedia.org/wiki/Heat_recovery_ventilation

    Heat recovery ventilation (HRV), also known as mechanical ventilation heat recovery (MVHR) is a ventilation system that recovers energy by operating between two air sources at different temperatures. It is used to reduce the heating and cooling demands of buildings. By recovering the residual heat in the exhaust gas, the fresh air introduced ...
