Heat pump dryer characteristics of four configurations, two open and two closed systems, are presented. The results are based on the simulation models developed in Part 1. Emphasis is given to the effects of ambient conditions, recirculating air ratio and evaporator bypass air ratio on the system pe
Heat pump dryer is a complex system because of the interaction of heat and mass transfer of the working fluids. Since the system cannot be completely close, ambient conditions (temperature and humidity) influence the performance of the system. To investigate the performance of the heat pump dryer th
Scope for energy recovery in this industry is substantial, particularly from the latent heat of the exhaust moist air. Using real operating data from a major Swedish mill, optimal energy conservation strategies were investigated using different heat pump systems in paper drying, Simulation results a
Heat pump dryer (HPD) performance described by computer simulation results in Parts 1 and 2 of this series of papers is here verified by experiments. An HPD designed to be operated in four configurations-two open systems and two partially closed systems-has been built. The variables in the experimen
