High temperature heat pump integration into district heating network [PDF]
Energy Conversion and Management, 2020 Abstract This study illustrates the potential of high temperature heat pumps (HTHPs) integration into district heating network (DHN) through a twofold approach, using DHN as a heat sink and source. It is used as a heat sink of HTHP that uses waste heat from the supermarket’s refrigeration system as a heat source whereas it is used as a heat source to

Improvements of high-temperature drying heat pumps
International Journal of Refrigeration, 2010 Inadequate integration and/or inappropriate operating parameters of heat pump dryers may lead to troubles as too high/low discharge/suction pressures, low dehumidification efficiency and even mechanical damage to the compressor. This paper will help fix a number of common design errors and/or omissions, and suggests original control methods to avoid ...
