Norway Joins HPT TCP Annex 59 – Heat Pumps for Drying

It is estimated that 10-15 percent of total energy consumption in the Norwegian industry is used for drying processes. However, a biproduct from drying is often steam, which is an excellent high quality heat source for heat pumps (HP). By utilizing the surplus heat from the drying process, a heat...
