Comparison of conventional flat-plate solar collector and solar boosted heat pump using unglazed collector for hot water production in small slaughterhouse

This study presents simulated results of solar water heating systems in a small slaughterhouse using two techniques. The first one is a normal solar water heating system using a flat-plate solar collector and the second one uses a solar-boosted heat pump system having a corrugated metal sheet roof a...
