Water Source Heat Pump Concepts, Principles And Classification - Water Source Heat Pump - Heat Pump

HC is a water source heat pump heat pump network using the earth's surface or shallow

water (such as groundwater, rivers and lakes), or artificial regeneration of water (industrial waste, geothermal tail water, etc.) can both heating cooling energy efficient air conditioning system. Use of heat pump water heat pump technology to achieve low level heat energy transferred to the high places, water bodies and ground storage at winter and summer as the heat source for heating and air conditioning of the cold source, that is, in winter, the water and the formation of the heat, "to take "out, raise the temperature, the supply of indoor heating; summer, the interior heat extracted from the body and released into the water to the formation.

From the academic point of view, when a use is water and ground (ground water) storage, and are all hot and cold water as a source of heat pump unit when the supply of carriers, can be categorized as water source heat pump system .

Under ASHRAEHandbook: HVACApplications. (1995) classification of geothermal energy resources will be divided into three categories according to temperature range, including ground source heat pump water source heat pump application class includes two methods: underground water and surface water source heat pump.

Two water source heat pump for the application of the following ways to make the appropriate description:

Groundwater heat pump system Groundwater heat pump system, also known as the deep recharge water source heat pump system. Group through the construction of a pumping groundwater out through the secondary heat exchanger or directly sent to the water source heat pump units, by extracting heat or release heat, by the injection well back underground irrigation group.

Surface water heat pump system Surface water heat pump system is taken directly or indirectly by way of heat transfer, use, including the river, river, lake, reservoir water and sea water as a heat pump source. Way attributable to the water source heat pump.

In addition, water source heat pump in the form of groundwater source heat pump can also be classified as seasonal underground storage applications. Nordic and Central European part of the country promote the use of shallow geothermal energy and underground storage for the building to provide winter and summer heating and air conditioning, more attention to these countries underground seasonal storage applications, has made the classification shown below:

Theoretically speaking, aquifer recharge energy storage applications and the deep water source heat pump means a lot in common, the two systems involved in underground construction technology, design principles and related theories are similar. Nordic and Central European part of the country for the Application of aquifer storage many of the results can be drawn on, used in deep recharge water source heat pump mode of related applications and research.

Above, water source heat pump ground source heat pump can be attributed to two branches: ground source heat pump and ground source heat pump; also be attributed to seasonal underground storage applications and the combination of heat pump application. But the need to emphasize that the classification of different application methods is to allow people to be more convenient to understand or promote the use of a technology, but in fact all that may exist between the different categories a certain intersection.

To seasonal underground thermal energy storage means, for example, the cold and heat source provides for natural heat source, such as the winter snow or the cold water back to the outdoor storage Wells poured into the summer, cold water extract was Xucun as the cold air source , summer high temperature of surface water poured into the regenerative Wells back in winter hot water extraction was Xucun heat as warm air; and when used as a heat pump to provide hot and cold sources, the means that winter will heat pump Unit export of cold water poured into the storage wells back to base, while the summer heat pump water back to the export group poured into the heat storage wells, the method can also be classified as a typical way of deep recharge water source heat pump.
