Overview of Heat-Pump Assisted Drying Systems, Part II: Data Provided vs. Results Reported

摘要

Part II of this overview investigates the general relevance of several published experimental and theoretical R&D studies on drying using electrically driven, vapor compression heat pumps coupled with air convective dryers. It also tries to evaluate the relevance of the data provided versus the results reported with various dryer-heat pump integrations aimed at improving drying performance for agro-food, timber, and unconventional products. The scope is to encourage future R&D work to provide the information required to help promote technological advancement and accelerate the industrial implementation of heat-pump-assisted drying systems.
