About the qualities and gratification of the innovative dual source heat pump (DSHP) for home heating, cooling down and household hot water (DHW) production. The research function was performed in the framework of the H2020 European project: Geotch ‘GEOthermal Technologies for economic Chilling and Heating’. The DSHP will be able to select the most favorable resource/sink in a manner that it may act as an aura-to-water heat pump using the air being a resource/kitchen sink, or as being a brine-to-water heat pump coupled to the ground. The DSHP is manufactured as being an outside ‘plug And play’ unit, working with R32 refrigerant and such as a variable speed compressor, which gives complete abilities for the effective modulating procedure. The DSHP was fully recognized in constant condition conditions at the IUIIE laboratory.

In order to assess its powerful overall performance as well as identify important control techniques to enhance its yearly operation, an entire integrated type of the DSHP system in TRNSYS like the DSHP and the rest of the program elements was created. An initial power assessment, completed to have an office building based in the Netherlands, demonstrates that this DSHP program would be able to achieve an identical effectiveness than a 100 % pure ground source heat pump (GSHP) program with fifty percent the earth source warmth exchanger area required. Consequently, the DSHP program could be a cost-effective alternative solution for home heating, cooling and DHW creation in structures, because the initial investment would be significantly decreased when compared with GSHPs, with similar as well as higher energy efficiency.

Based on the Heat pump industry, structures account for almost 1 / 3rd in the final worldwide energy consumption, and they are generally an essential way to obtain Carbon dioxide emissions. In particular, heating, air flow and atmosphere-conditioning techniques (Heating and air conditioning) make up roughly 50 % of worldwide power consumption in structures. The industry is expanding, so it is bound to improve its energy consumption. Therefore, reduction of power consumption and using energy from renewable sources in the building sector constitute essential vectors to reduce the green house gasoline emissions. In terms of room heating and air conditioning using shallow geothermal power as a renewable energy resource, floor resource heat pump (GSHP) techniques turn out to be one of the most effective heating and cooling green technologies now available. These systems make use of the ground being a source of heat or warmth kitchen sink, based on the period, to be able to offer structures with heating and cooling, correspondingly. Nevertheless, they imply using refrigerants within the heat pump refrigeration cycle that might provide an impact within the ozone layer depletion and climate change.

Thankfully, the present pattern is always to switch to new refrigerants without any effect within the ozone layer and a reduced climatic change possible. Nowadays, the GSHPs that are available in the market work with these type of refrigerants, including HFCs or HFOs (e.g. R32). Regarding the direct and indirect emissions, the existing GSHPs are generally manufacturer protect equipment, and so the direct pollutants of refrigerant are negligible and virtually the totality in the refrigerant is retrieved after the heat pump life. Moreover, because the energy intake of these techniques is less than traditional ones, the indirect emissions are also reduced.

GSHP systems have proved to be better than conventional atmosphere-to-water heat pumping systems, as demonstrated through the heat pump business, who determined that GSHP techniques can lead up to a 40Percent savings in yearly electrical power usage, in comparison to air to prvtur water conventional heat pumps. Nevertheless, one of many drawbacks of GSHPs is the high investment price. Therefore, a reduction in both construction and procedure costs is required for these systems to get successful, particularly for Southern European countries in which the market of GSHP systems has not removed but.
