Abstract

With the aim of energy saving and cost reduction for lumber drying system, we built a prototype a lumber drying system with a solar thermal collector, a water circulation type heat pump and a waste heat recovery heat exchanger. As a result of experimental study, this system can reduce primary energy consumption by 56% and energy cost by 60% compared to exsinting a steam drying system with a heavy oil-fired boiler, keeping the kiln-dried lumber quality high. In addition, we obtained some design guides for commercialization of this system.
