Energy harvesting controls for solar direct–drive cooling systems: Laboratory testing report


This report presents the methods and findings from laboratory testing of two energy harvesting control (EHC) prototypes with three different Performance, Quality and Safety prequalified solar direct–drive refrigerators from three different manufacturers. The primary goals of the testing were to inform potential specifications for EHCs, test the specific prototypes, and collect data to answer a number of questions raised by the possible introduction of EHCs to vaccine cold chain systems.
