  2. Fan coil unit - Wikipedia

    en.wikipedia.org/wiki/Fan_coil_unit

    A fan coil unit (FCU), also known as a Vertical Fan Coil Unit (VFCU), is a device consisting of a heat exchanger (coil) and a fan. FCUs are commonly used in HVAC systems of residential, commercial, and industrial buildings that use ducted split air conditioning or central plant cooling.

  3. Which Way Should A Ceiling Fan Turn In The Winter? Experts ...

    This is usually marked, but you can also turn the fan on low to observe which way the blades spin. Use the Right Speed: High speeds create a cooling effect you don't want in winter.

  4. Heat pump and refrigeration cycle - Wikipedia

    en.wikipedia.org/wiki/Heat_pump_and...

    Thermodynamic heat pump cycles or refrigeration cycles are the conceptual and mathematical models for heat pump, air conditioning and refrigeration systems. [1] A heat pump is a mechanical system that transmits heat from one location (the "source") at a certain temperature to another location (the "sink" or "heat sink") at a higher temperature. [2]

  5. Centrifugal fan - Wikipedia

    en.wikipedia.org/wiki/Centrifugal_fan

    A centrifugal fan is a mechanical device for moving air or other gases in a direction at an angle to the incoming fluid. Centrifugal fans often contain a ducted housing to direct outgoing air in a specific direction or across a heat sink; such a fan is also called a blower, blower fan, or squirrel-cage fan (because it looks like a hamster wheel).

  6. Refrigeration - Wikipedia

    en.wikipedia.org/wiki/Refrigeration

    Peltier coolers are often used where a traditional vapor-compression cycle refrigerator would be impractical or take up too much space, and in cooled image sensors as an easy, compact and lightweight, if inefficient, way to achieve very low temperatures, using two or more stage peltier coolers arranged in a cascade refrigeration configuration ...

  7. 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.

  8. Subcooling - Wikipedia

    en.wikipedia.org/wiki/Subcooling

    Superheating is analogous to subcooling in an operative way, i.e., occurring prior to a stage where refrigerant in a liquid-gas state would disrupt the cycle (uncompressible liquid-gas mixtures will destroy the compressor) and both processes can be coupled using an internal heat exchanger.

  9. Absorption refrigerator - Wikipedia

    en.wikipedia.org/wiki/Absorption_refrigerator

    Common absorption refrigerators use a refrigerant with a very low boiling point (less than −18 °C (0 °F)) just like compressor refrigerators.Compression refrigerators typically use an HCFC or HFC, while absorption refrigerators typically use ammonia or water and need at least a second fluid able to absorb the coolant, the absorbent, respectively water (for ammonia) or brine (for water).
