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 ...
