Regarding the qualities and satisfaction of an innovative dual source heat pump (DSHP) for home heating, cooling down and domestic hot water (DHW) production. The investigation work was performed inside the framework of the H2020 European project: Geotch ‘GEOthermal Technology for financial Chilling and Heating’. The DSHP has the capacity to select the most favorable resource/sink in such a way that it could work as an air-to-water heat pump using the air as being a source/kitchen sink, or as a brine-to-water heat pump combined to the ground. The DSHP is manufactured as being an outdoor ‘plug And play’ device, utilizing R32 refrigerant and such as a variable velocity compressor, which gives full capabilities for the efficient modulating procedure. The DSHP was fully characterized in constant state conditions at the IUIIE laboratory.

To be able to assess its dynamic performance and also to identify important manage strategies to enhance its yearly procedure, a total incorporated model of the DSHP system in TRNSYS like the DSHP and all the other system components was created. A first energy assessment, performed to have an workplace developing based in the Holland, proves the DSHP program could achieve an identical effectiveness than a pure floor resource heat pump (GSHP) system with half the floor resource warmth exchanger area required. Consequently, the DSHP system could be a cost-effective option solution for heating, cooling and DHW creation in buildings, since the preliminary purchase could be significantly decreased compared to GSHPs, with a similar as well as greater energy effectiveness.
Based on the Heat pump business, structures make up nearly 1 / 3rd from the last global energy consumption, and they are an essential way to obtain Carbon dioxide emissions. Specifically, home heating, ventilation and air-conditioning systems (HVAC) account for approximately half of global energy usage in buildings. The industry is expanding, therefore it is certain to increase its energy consumption. Therefore, lowering of power usage and the use of power from green resources within the developing industry constitute important vectors to reduce the green house gas emissions. In terms of space heating and air conditioning using superficial geothermal energy as a renewable energy resource, floor resource heat pump (GSHP) systems become just about the most efficient heating and air conditioning green systems now available. These systems utilize the floor as a heat source or heat sink, depending on the season, in order to offer structures with heating and air conditioning, correspondingly. However, they imply the use of refrigerants in the heat pump refrigeration period that might come with an effect in the ozone coating depletion and climate change.
Fortunately, the existing pattern is to switch to new refrigerants without any impact inside the ozone layer as well as a reduced climate change potential. Nowadays, the GSHPs which can be on the market are working with thesea kind of refrigerants, such as HFCs or HFOs (e.g. R32). Regarding the direct and indirect pollutants, the current GSHPs are generally manufacturer shield gear, so the direct pollutants of refrigerant are minimal and virtually the totality from the refrigerant is retrieved after the heat pump lifestyle. Furthermore, since the energy usage of these techniques is lower than traditional types, the indirect pollutants can also be reduced.
GSHP techniques have proved to be more efficient than traditional air-to-water warmth pumping systems, as shown from the heat pump industry, who determined that GSHP techniques may lead as much as a 40% savings in annual electrical power consumption, in comparison to air to prvtur water conventional warmth pumping systems. Nevertheless, one of the main disadvantages of GSHPs could be the higher purchase price. Consequently, a reduction in both construction and operation costs is required for these particular techniques to be effective, especially for Southern European countries in which the marketplace of GSHP systems has not taken off yet.
