Concerning the qualities and gratification of the revolutionary double resource heat pump (DSHP) for home heating, cooling and household hot water (DHW) production. The study function was carried out within the structure in the H2020 European project: Geotch ‘GEOthermal Technologies for financial Chilling and Heating’. The DSHP will be able to choose the most favourable resource/sink in a way that it can work as an air-to-water heat pump utilizing the atmosphere as a source/sink, or as a brine-to-water heat pump combined to the floor. The DSHP is manufactured as being an outdoor ‘plug And play’ unit, dealing with R32 refrigerant and together with a variable speed compressor, that gives full abilities to have an efficient modulating procedure. The DSHP was completely characterized in steady condition problems in the IUIIE lab.

So that you can assess its powerful performance and to identify important control strategies to optimize its yearly operation, a complete integrated model of the DSHP program in TRNSYS such as the DSHP and the rest of the system elements was developed. The first power evaluation, carried out for an office building based in the Holland, proves that this DSHP program can reach a similar efficiency when compared to a pure ground resource heat pump (GSHP) system with fifty percent the earth resource warmth exchanger area needed. Consequently, the DSHP program could become a cost-effective alternative solution for heating, chilling and DHW production in buildings, because the initial investment could be considerably reduced when compared with GSHPs, with a similar or even greater energy effectiveness.

In accordance with the Heat pump industry, structures take into account nearly 1 / 3 of the final worldwide energy usage, plus they are an essential way to obtain CO2 pollutants. Particularly, home heating, ventilation and air-conditioning techniques (HVAC) make up approximately half of global power consumption in buildings. The sector is expanding, so it is bound to improve its power consumption. Therefore, lowering of energy consumption and using power from renewable sources within the building industry constitute essential vectors to reduce the greenhouse gasoline emissions. When it comes to space cooling and heating utilizing superficial geothermal energy as being a renewable power source, floor source heat pump (GSHP) systems become one of the most efficient heating and cooling renewable technologies currently available. These techniques make use of the ground being a source of heat or heat kitchen sink, dependant upon the period, so that you can provide structures with heating and air conditioning, correspondingly. Nevertheless, they imply the usage of refrigerants inside the heat pump refrigeration period that might come with an effect inside the ozone coating depletion and climatic change.

Fortunately, the existing trend would be to switch to new refrigerants without any impact in the ozone layer as well as a reduced global warming potential. Nowadays, the GSHPs which can be available in the market work with thesea kind of refrigerants, including HFCs or HFOs (e.g. R32). With regards to the direct and indirect emissions, the current GSHPs are often manufacturer shield gear, and so the direct emissions of refrigerant are negligible and practically the totality of the refrigerant is retrieved at the conclusion of the heat pump lifestyle. Furthermore, since the energy usage of these techniques is lower than traditional ones, the indirect emissions can also be reduced.

GSHP systems have became better than conventional air-to-water heat pumps, as shown by the heat pump industry, who determined that GSHP techniques often leads up to and including 40% cost savings in annual electrical power consumption, compared to air to prvtur water conventional heat pumping systems. Nevertheless, one of the primary disadvantages of GSHPs is their higher purchase cost. Therefore, a decrease in both construction and procedure expenses is necessary for such techniques to get successful, particularly for Southern Countries in europe where marketplace of GSHP techniques has not yet taken off yet.
