  2. Heat pump and refrigeration cycle - Wikipedia

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

    e. Thermodynamic heat pump cycles or refrigeration cycles are the conceptual and mathematical models for heat pump, air conditioning and refrigeration systems. 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. [1]

  3. Air source heat pump - Wikipedia

    en.wikipedia.org/wiki/Air_source_heat_pump

    Heat pump on balcony of apartment. An air source heat pump (ASHP) is a heat pump that can absorb heat from air outside a building and release it inside; it uses the same vapor-compression refrigeration process and much the same equipment as an air conditioner, but in the opposite direction. ASHPs are the most common type of heat pump and ...

  4. Heat pump - Wikipedia

    en.wikipedia.org/wiki/Heat_pump

    t. e. A heat pump is a device that consumes energy (usually electricity) to transfer heat from a cold heat sink to a hot heat sink. Specifically, the heat pump transfers thermal energy using a refrigeration cycle, cooling the cool space and warming the warm space. [1] In cold weather, a heat pump can move heat from the cool outdoors to warm a ...

    An air source heat pump looks like an air conditioning unit on the outside of buildings. It works a bit like a fridge in reverse, using electricity to extract energy from the outside air to ...

  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. Thermodynamic cycle - Wikipedia

    en.wikipedia.org/wiki/Thermodynamic_cycle

    Thermodynamic heat pump cycles are the models for household heat pumps and refrigerators. There is no difference between the two except the purpose of the refrigerator is to cool a very small space while the household heat pump is intended to warm or cool a house. Both work by moving heat from a cold space to a warm space.

  8. Central heating - Wikipedia

    en.wikipedia.org/wiki/Central_heating

    Central heating. A central heating system provides warmth to a number of spaces within a building from one main source of heat. It is a component of heating, ventilation, and air conditioning (short: HVAC) systems, which can both cool and warm interior spaces. A central heating system has a furnace that converts fuel or electricity to heat.

  9. Absorption-compression heat pump - Wikipedia

    P-T Diagram showing the temperature gliding in binary heat pump. This behaviour increase the efficiency of ACHP Ammonia toxicity is the main drawback of ACHP. The main advantage with respect to compression heat pump is that the compression-absorption heat pumps allow the heat to be transfer with a temperature glide.
