Regarding the characteristics and gratification of an innovative double resource heat pump (DSHP) for home heating, cooling down and domestic hot water (DHW) creation. The study work was completed within the framework in the H2020 Western task: Geotch ‘GEOthermal Technologies for financial Chilling and Heating’. The DSHP will be able to choose the most favourable source/kitchen sink in such a way that it may work as an air-to-water heat pump making use of the air as being a source/kitchen sink, or as being a brine-to-water heat pump combined to the ground. The DSHP is produced as being an outdoor ‘plug & play’ unit, working with R32 refrigerant and such as a variable velocity compressor, which gives complete abilities for an effective modulating operation. The DSHP was fully recognized in steady condition conditions in the IUIIE laboratory.

In order to assess its dynamic performance and to determine important control approaches to optimize its yearly operation, an entire integrated model of the DSHP system in TRNSYS including the DSHP and all the other system components was created. An initial power evaluation, performed for the office building based in the Holland, proves that this DSHP program could achieve a similar efficiency compared to a pure ground source heat pump (GSHP) program with half the earth resource warmth exchanger region needed. Consequently, the DSHP system could turn into a cost-effective option solution for home heating, cooling and DHW creation in buildings, since the preliminary purchase would be considerably reduced in comparison to GSHPs, with a similar or even higher energy efficiency.
Based on the Heat pump business, buildings account for almost 1 / 3rd in the final global energy consumption, and they are generally an essential source of Carbon dioxide emissions. Particularly, home heating, ventilation and air-conditioning systems (HVAC) take into account approximately 50 % of global energy usage in buildings. The industry is expanding, so it is bound to increase its energy usage. Therefore, lowering of power consumption and the use of energy from green resources in the developing sector make up important vectors to minimize the greenhouse gasoline pollutants. With regards to space heating and cooling utilizing superficial geothermal power as a alternative energy resource, ground resource heat pump (GSHP) systems become probably the most efficient heating and cooling renewable systems available today. These systems make use of the ground being a source of heat or warmth sink, depending on the season, to be able to offer buildings with heating and air conditioning, correspondingly. However, they imply using refrigerants inside the heat pump refrigeration cycle which may have an impact in the ozone layer depletion and climate change.
Fortunately, the present pattern would be to change to new refrigerants without any impact within the ozone coating along with a reduced climate change possible. Nowadays, the GSHPs which are on the market will work with these type of refrigerants, like HFCs or HFOs (e.g. R32). Concerning the direct and indirect emissions, the current GSHPs are often manufacturer shield equipment, and so the direct emissions of refrigerant are negligible and virtually the totality from the refrigerant is recovered at the end of the heat pump lifestyle. Furthermore, as the power consumption of these techniques is lower than traditional types, the indirect emissions are also reduced.
GSHP techniques have turned out to be more effective than traditional atmosphere-to-water warmth pumps, as demonstrated by the heat pump industry, who determined that GSHP systems can lead as much as a 40Percent cost savings in yearly electrical power usage, when compared with air to prvtur water conventional heat pumps. Nonetheless, one of the main disadvantages of GSHPs is the high investment price. Consequently, a decrease in both building and operation costs is needed for these particular systems to get successful, particularly for Southern Countries in europe where the marketplace of GSHP techniques has not yet removed but.
