High temperature heat pumps applying natural fluids
, 2014 The heat pump market has so far mainly focused on residential heat pumps for space heating and domestic hot water production. That means that industrial heat pumps are successfully integrated as low temperature heat recovery systems but rarely employed in processes with heat requirements above 100°C, due to very high investment costs, or non-existing ...
