CLOSED LOOP HEAT PUMP SYSTEM IN DRYFICIENCY
Closed loop heat pumps are a well-known technology in residential and industrial applications. It can extract, otherwise unused heat, from ambient and waste heat to deliver higher grade energy. In particular, industrial drying with air as drying agent is one of the most appropriate processes to utilize waste heat from industry. The exhaust air stream will be cooled, and thus dried, on the low pressure side of the closed loop heat pump. This energy, including sensible and latent heat, will be transferred to process temperatures on the high pressure side of the closed loop heat pump and reused to heat the dried air again, to reach starting conditions.
