[EN] Heat pumps that work with a high degree of subcooling in subcritical systems have shown a significant margin
of improvement when working with sanitary hot water applications. Recently, two different approaches ...
[EN] The performance of a transcritical cycle is highly dependent on the rejection pressure. The optimal rejection pressure depends mainly on the inlet and outlet temperatures at the heat sink (secondary fluid). For the ...

[EN] According to the European Commission, heating, cooling and domestic hot water (DHW) production imply 79% of the total energy consumed in households. Moreover, as 84% of this energy is still generated from fossil fuels, ...
[EN] The use of heat pumps in order to produce sanitary hot water have been demonstrated as a very efficient alternative to traditional boilers. Nevertheless, the high water temperature lift (usually from 10 degrees C to ...
