  1. Heat pump

    A heat pump is a device that can heat a building (or part of a building) by transferring thermal energy from the outside using a refrigeration cycle. Many heat pumps can also operate in the opposite direction, cooling the building by removing heat from the enclosed space and rejecting it outside. Units that only provide cooling are called air conditioners. When in heating mode, a refrigerant at outside temperature is being compressed. As a result, the refrigerant becomes hot. This thermal energy can be transferred to an indoor unit. After being moved outdoors again, the refrigerant is decompressed — evaporated. It has lost some of its thermal energy and returns colder than the environment. It can now take up the surrounding energy from the air or from the ground before the process repeats. Compressors, fans, and pumps run with electric energy. Air source heat pumps are the most common models, while other types include ground source heat pumps, water source heat pumps and exhaust air heat pumps. Large-scale heat pumps are also used in district heating systems.The efficiency of a heat pump is expressed with a coefficient of performance (COP), or seasonal coefficient of performance (SCOP). The higher the number, the more efficient a heat pump is and the less energy it consumes. When used for space heating, heat pumps are typically much more energy efficient than simple electrical resistance heaters. Because of their high efficiency and the increasing share of fossil-free sources in electrical grids, heat pumps can play a key role in climate change mitigation. With 1 kWh of electricity, they can transfer 3 to 6 kWh of thermal energy into a building. The carbon footprint of heat pumps depends on how electricity is generated, but they usually reduce emissions in mild climates. Heat pumps could satisfy over 80% of global space and water heating needs with a lower carbon footprint than gas-fired condensing boilers: however, as of 2021 they only meet 10%.

  1. heat pump

    A heat pump is a device or system that transfers heat energy from a source of heat, often from the outside air or ground, to a destination such as a building or a home. It employs the principles of refrigeration and works by absorbing heat from cooler places and releasing it into warmer ones. This process can be reversed in order to cool the destination in warmer weather, thus providing both heating and cooling functions.

  1. Heat pump

    A heat pump is a device that transfers heat energy from a heat source to a heat sink against a temperature gradient. Heat pumps are designed to move thermal energy opposite the direction of spontaneous heat flow. A heat pump uses some amount of external high-grade energy to accomplish the desired transfer of thermal energy from heat source to heat sink. While compressor-driven air conditioners and freezers are familiar examples of heat pumps, the term "heat pump" is more general and applies to HVAC devices used for space heating or space cooling. When a heat pump is used for heating, it employs the same basic refrigeration-type cycle used by an air conditioner or a refrigerator but in the opposite direction, releasing heat into the conditioned-space rather than the surrounding environment. In this use, heat pumps generally draw heat from the cooler external air or from the ground.

Examples of heat pump in a Sentence

  1. Arlene Anderson:

    That heat pump is basically run from heat in the ground, the fuel is basically the Earth source heat.

  2. Greenpeace UK:

    If the government wants a chance to catch up, it needs a proper strategy and enough cash to clean up our homes on a massive scale. This means substantial grants for heat pump installations, especially for the poorest families, removing VAT on green home technologies and a phase out of gas boilers early next decade.

  3. Ben King:

    All those things can combine to help get more heat pumps deployed, a heat pump is more energy efficient than something like a furnace. The less electricity you're consuming, the better off you are.
