About the characteristics and satisfaction of an revolutionary double source heat pump (DSHP) for heating systems, cooling and household hot water (DHW) production. The research work was completed within the framework from the H2020 European project: Geotch ‘GEOthermal Technologies for economic Chilling and Heating’. The DSHP will be able to choose the most favorable source/kitchen sink in a manner that it may work as an aura-to-water heat pump using the air as a source/sink, or as a brine-to-water heat pump combined to the ground. The DSHP is manufactured being an outdoor ‘plug & play’ unit, working with R32 refrigerant and including a variable velocity compressor, which provides complete abilities for the efficient modulating procedure. The DSHP was fully characterized in steady condition conditions on the IUIIE lab.

So that you can assess its dynamic overall performance and also to identify key control approaches to optimize its yearly operation, a total incorporated type of the DSHP program in TRNSYS including the DSHP and all the other system elements was developed. A first energy evaluation, carried out for an workplace developing found in the Holland, demonstrates that the DSHP program can reach a similar efficiency than a pure ground source heat pump (GSHP) program with half the ground resource warmth exchanger area required. Consequently, the DSHP system could turn into a inexpensive alternative remedy for home heating, chilling and DHW creation in buildings, as the initial investment could be significantly decreased in comparison to GSHPs, with similar or perhaps higher power effectiveness.
According to the Heat pump industry, structures take into account almost one third in the final worldwide power usage, and they are generally a significant source of CO2 pollutants. Particularly, heating, air flow and atmosphere-conditioning techniques (HVAC) make up approximately one half of worldwide energy consumption in buildings. The sector is expanding, so it is bound to improve its power consumption. Consequently, decrease in power usage and the usage of energy from renewable sources within the developing industry constitute essential vectors to minimize the greenhouse gasoline pollutants. When it comes to room cooling and heating utilizing superficial geothermal power as being a renewable power source, ground resource heat pump (GSHP) techniques turn out to be one of the most effective cooling and heating green systems now available. These systems utilize the ground as being a source of heat or heat kitchen sink, based on the period, in order to provide structures with heating and cooling, correspondingly. However, they imply the use of refrigerants within the heat pump refrigeration cycle that might come with an impact within the ozone layer depletion and global warming.
Fortunately, the existing pattern would be to change to new refrigerants with no impact inside the ozone layer along with a reduced climatic change possible. These days, the GSHPs which are on the market work with thesea kind of refrigerants, such as HFCs or HFOs (e.g. R32). With regards to the direct and indirect pollutants, the current GSHPs are often manufacturer shield equipment, so the immediate pollutants of refrigerant are negligible and virtually the totality from the refrigerant is retrieved at the conclusion of the heat pump life. Moreover, since the energy consumption of these systems is less than traditional ones, the indirect emissions can also be decreased.
GSHP techniques have became better than traditional air-to-water heat pumps, as demonstrated by the heat pump industry, who determined that GSHP systems can lead up to a 40% savings in yearly electrical power consumption, when compared with atmosphere to prvtur water conventional warmth pumping systems. Nonetheless, one of the main drawbacks of GSHPs could be the high purchase cost. Therefore, a decrease in both construction and operation costs is required for these systems to be successful, particularly for The southern area of Countries in europe in which the marketplace of GSHP systems has not taken off yet.
