Heat pumps (HPs) and their individual components experience a significant share of operation away from the design point, due to both sink and source temperature variations as well as operation at part load. In the present study, we expand a generaliz

The autonomy time of an icelined solar powered vaccine cooler expresses the amount of hours the cooler is able to keep vaccines within an acceptable temperature range during low solar radiation conditions, i.e. when the compressor of the cooling syst

EU regulations 2015/1095 and 2015/1094 of 5 May 2015 have been implemented for professional refrigerated counters along with the test standard EN 16825. These regulations rates most current counters as class C or D and consequently there is an ongoin

Industrial heat pumps (IHP) are a major contributor in the transformation towards a future energy system based on electrical power. The main barrier for IHP integration is the operating cost and thereby the COP. COP is highly dependent on the tempera
