The present work presents a thermodynamic performance analysis of a solar dryer with an evacuated-tube collector. Drying experiments for apples, carrots and apricots were conducted, after a preliminary stage of the investigation which included measurements for the determination of the collector...

In the present work, a method is proposed for the testing and evaluation of the performance of combined solar thermal heat pump hot water systems. The method is based on the Dynamic System Testing (DST) method for solar thermal systems. The evaluation of the system performance requires the...
