About the characteristics and performance of your revolutionary dual resource heat pump (DSHP) for heating, cooling and domestic hot water (DHW) production. The study function was carried out within the framework in the H2020 Western task: Geotch ‘GEOthermal Technologies for economic Chilling and Heating’. The DSHP will be able to choose the most favorable source/sink in a way that it may act as an air-to-water heat pump making use of the atmosphere being a resource/kitchen sink, or as a brine-to-water heat pump coupled to the floor. The DSHP is manufactured being an outside ‘plug And play’ unit, working with R32 refrigerant and including a variable velocity compressor, that gives complete abilities for an effective modulating operation. The DSHP was fully characterized in steady state problems at the IUIIE lab.

In order to assess its powerful overall performance as well as determine important control techniques to optimize its yearly operation, an entire integrated type of the DSHP program in TRNSYS such as the DSHP and the rest of the program components was developed. The first power assessment, completed for an workplace building based in the Holland, proves that this DSHP program would be able to achieve an identical effectiveness compared to a 100 % pure ground resource heat pump (GSHP) program with fifty percent the floor resource heat exchanger region needed. Consequently, the DSHP program could turn into a inexpensive alternative solution for heating, cooling and DHW production in structures, because the initial investment will be considerably reduced in comparison to GSHPs, with a similar as well as higher energy efficiency.

In accordance with the Heat pump industry, buildings take into account almost 1 / 3rd from the final global energy consumption, and they are generally an important source of Carbon dioxide emissions. In particular, heating, air flow and atmosphere-conditioning systems (HVAC) account for roughly 50 % of global power consumption in buildings. The sector is growing, so it is certain to improve its power usage. Consequently, reduction of energy usage and the usage of energy from renewable resources within the developing sector make up essential vectors to reduce the green house gasoline pollutants. In terms of room heating and cooling utilizing superficial geothermal energy as a renewable power resource, ground source heat pump (GSHP) systems become one of the most efficient heating and cooling green systems now available. These techniques utilize the floor being a source of heat or warmth sink, based on the season, so that you can offer structures with heating and air conditioning, correspondingly. Nevertheless, they imply the usage of refrigerants in the heat pump refrigeration period which may have an effect within the ozone coating depletion and global warming.

Fortunately, the existing trend is always to change to new refrigerants with no effect in the ozone coating and a reduced climate change potential. These days, the GSHPs that are in the market work with these refrigerants, including HFCs or HFOs (e.g. R32). With regards to the direct and indirect pollutants, the present GSHPs are generally manufacturer shield gear, so the immediate pollutants of refrigerant are negligible and practically the totality from the refrigerant is retrieved at the end of the heat pump lifestyle. Moreover, because the energy usage of these techniques is less than conventional ones, the indirect pollutants can also be reduced.

GSHP techniques have proved to be more effective than conventional atmosphere-to-water heat pumping systems, as demonstrated from the heat pump business, who concluded that GSHP techniques may lead up to and including 40% savings in annual electrical power consumption, when compared with air to prvtur water traditional warmth pumping systems. Nonetheless, one of the primary drawbacks of GSHPs could be the high investment cost. Consequently, a reduction in each building and procedure expenses is necessary for these systems to be successful, especially for Southern European countries where the marketplace of GSHP systems has not yet removed yet.
