Regarding the qualities and satisfaction of an revolutionary double source heat pump (DSHP) for heating systems, cooling down and household hot water (DHW) creation. The research work was performed inside the structure from the H2020 European task: Geotch ‘GEOthermal Technologies for economic Cooling and Heating’. The DSHP will be able to select the most favourable source/sink in such a way that it may serve as an air-to-water heat pump making use of the air as being a resource/sink, or being a brine-to-water heat pump coupled to the floor. The DSHP is manufactured as being an outside ‘plug & play’ unit, dealing with R32 refrigerant and including a variable velocity compressor, which provides full abilities to have an efficient modulating procedure. The DSHP was completely recognized in constant state problems in the IUIIE lab.

In order to assess its dynamic performance and to identify key control strategies to enhance its yearly procedure, a total integrated model of the DSHP system in TRNSYS including the DSHP and all the other program components was developed. The first energy evaluation, completed for an workplace building based in the Netherlands, demonstrates that the DSHP program would be able to reach an identical efficiency when compared to a 100 % pure floor source heat pump (GSHP) program with fifty percent the ground resource warmth exchanger area required. Therefore, the DSHP program could become a cost-effective option remedy for heating, chilling and DHW creation in structures, because the preliminary investment will be considerably decreased when compared with GSHPs, with a similar as well as higher energy efficiency.

Based on the Heat pump industry, structures account for almost 1 / 3rd in the final worldwide power consumption, plus they are an important way to obtain CO2 emissions. In particular, heating, ventilation and atmosphere-conditioning techniques (Heating and air conditioning) take into account roughly 50 % of global power usage in buildings. The sector is expanding, so it will be bound to increase its power usage. Consequently, decrease in power usage and the usage of energy from renewable resources inside the developing sector make up important vectors to lessen the green house gasoline emissions. When it comes to space cooling and heating using superficial geothermal energy being a renewable energy resource, ground source heat pump (GSHP) techniques turn out to be just about the most effective cooling and heating green technologies currently available. These techniques utilize the ground being a source of heat or heat kitchen sink, based on the period, to be able to provide structures with heating and air conditioning, respectively. However, they imply the use of refrigerants within the heat pump refrigeration period that may come with an impact inside the ozone coating depletion and climatic change.

Thankfully, the present trend would be to change to new refrigerants without effect in the ozone layer as well as a reduced global warming potential. Nowadays, the GSHPs which can be available in the market work with these type of refrigerants, like HFCs or HFOs (e.g. R32). Concerning the immediate and indirect pollutants, the present GSHPs are often factory shield equipment, therefore the direct emissions of refrigerant are negligible and virtually the totality from the refrigerant is retrieved at the end of the heat pump life. Furthermore, as the power intake of these techniques is less than traditional types, the indirect emissions can also be decreased.

GSHP techniques have turned out to be more efficient than conventional air-to-water heat pumping systems, as demonstrated from the heat pump industry, who determined that GSHP techniques can lead as much as a 40% savings in annual electrical power consumption, in comparison to atmosphere to prvtur water conventional heat pumping systems. Nevertheless, one of the primary disadvantages of GSHPs is their higher purchase price. Consequently, a decrease in each building and procedure costs is needed for such systems to get effective, particularly for Southern European countries in which the market of GSHP systems has not yet removed but.
