Experimental study on cascade heat pump dryer with a solar collector under low temperature outdoor air environment

A heat pump dryer can save more energy than other dryers since its drying efficiency is 2-3 times higher than that of other types of dryers. However, the lower bound of evaporating temperature for an R134a heat pump cycle ranges from 5 to 10°C, when the outdoor air temperature closely approaches the...
