Regarding the characteristics and satisfaction of an innovative double source heat pump (DSHP) for heating, cooling down and domestic hot water (DHW) creation. The study work was carried out in the structure of the H2020 Western project: Geotch ‘GEOthermal Technology for financial Chilling and Heating’. The DSHP is able to select the most favorable resource/sink in a way that it can serve as an air-to-water heat pump making use of the atmosphere as being a source/sink, or as being a brine-to-water heat pump coupled to the ground. The DSHP is produced being an outdoor ‘plug & play’ device, dealing with R32 refrigerant and including a adjustable velocity compressor, which gives complete capabilities to have an effective modulating operation. The DSHP was fully characterized in steady state problems in the IUIIE laboratory.

In order to assess its powerful performance and also to determine key manage strategies to enhance its annual operation, an entire integrated style of the DSHP program in TRNSYS like the DSHP and the rest of the program elements was made. An initial power evaluation, completed for the office building based in the Holland, proves that the DSHP program can reach a similar effectiveness than a 100 % pure floor resource heat pump (GSHP) system with half the floor source heat exchanger area needed. Therefore, the DSHP system could become a inexpensive option remedy for home heating, chilling and DHW production in structures, since the initial purchase could be significantly reduced in comparison to GSHPs, with a similar or perhaps higher power effectiveness.
Based on the Heat pump business, structures make up almost 1 / 3rd of the last global energy consumption, and they are a significant way to obtain Carbon dioxide pollutants. Particularly, heating, ventilation and air-conditioning techniques (Heating and air conditioning) account for roughly 50 % of worldwide power consumption in buildings. The industry is growing, therefore it is certain to improve its energy usage. Consequently, decrease in power usage and using power from renewable resources inside the building sector constitute essential vectors to minimize the green house gas pollutants. In terms of space heating and cooling utilizing shallow geothermal energy as being a renewable energy source, floor resource heat pump (GSHP) systems turn out to be just about the most effective cooling and heating renewable systems available today. These systems utilize the ground as being a source of heat or warmth sink, based on the season, so that you can offer structures with cooling and heating, respectively. However, they imply the use of refrigerants within the heat pump refrigeration period that might provide an effect within the ozone layer depletion and global warming.
Thankfully, the current pattern is to change to new refrigerants without any effect within the ozone layer as well as a low climate change potential. These days, the GSHPs which can be available in the market are working with these refrigerants, like HFCs or HFOs (e.g. R32). With regards to the immediate and indirect pollutants, the existing GSHPs are generally factory shield equipment, so the immediate pollutants of refrigerant are negligible and practically the totality in the refrigerant is retrieved at the conclusion of the heat pump lifestyle. Furthermore, as the power intake of these systems is less than conventional ones, the indirect emissions are also reduced.
GSHP systems have became better than conventional atmosphere-to-water heat pumps, as demonstrated from the heat pump industry, who determined that GSHP techniques may lead up to a 40Percent savings in annual electrical power consumption, when compared with air to prvtur water traditional warmth pumping systems. Nonetheless, one of the primary disadvantages of GSHPs is their higher investment cost. Therefore, a reduction in both construction and procedure costs is necessary for these systems to be effective, specifically for Southern European countries in which the market of GSHP systems has not removed yet.
