How heat pumps achieve energy savings and CO2 emissions reductionHeat pumps and energy savingThis section gives a brief introduction to heat pumps. Based on six basic facts about heat supply the value of heat pumps is discussed. It is argued that heat pumps are very energy efficient, and therefore environmentally benign. An efficient technologyHeat pumps […]

Heat Pump Technology Heat flows naturally from a higher to a lower temperature. Heat pumps, however, are able to force the heat flow in the other direction, using a relatively small amount of high quality drive energy (electricity, fuel, or high-temperature waste heat). Thus heat pumps can transfer heat from natural heat sources in the […]

Heat sources The technical and economic performance of a heat pump is closely related to the characteristics of the heat source. An ideal heat source for heat pumps in buildings has a high and stable temperature during the heating season, is abundantly available, is not corrosive or polluted, has favourable thermophysical properties, and its utilisation […]

Heat pump performanceThe heat delivered by a heat pump is theoretically the sum of the heat extracted from the heat source and the energy needed to drive the cycle. The steady-state performance of an electric compression heat pump at a given set of temperature conditions is referred to as the coefficient of performance (COP). It […]

Heat pumps in residential and commercial buildingsFunctionsHeat pumps for heating and cooling buildings can be divided into four main categories depending on their operational function: Heating-only heat pumps, providing space heating and/or water heating. Heating and cooling heat pumps, providing both space heating and cooling.The most common type is the reversible air-to-air heat pump, which […]

European – Air-source heat pump SummaryThe purpose of the project was to build a low energy and low cost prefabricated house without compromising the comfort. Due to the overall reduced energy consumption in low energy houses the proportion of the heat required for DHW increases from 30% to 40%. This sets new requirements for a […]
