Scientists have utilized two blower fans with two roll-bonded bare plates to create a heat pump that can operate in variety of ambient temperature and solar radiation conditions. The system has an average daily coefficient of performance of 3.24.An international research team has developed a novel solar-air dual-source heat pump (SAHP) for water heating applications. The system's innovation lies in using a blower fan that enables forced convection during partial sunshine and diffuse light conditions. Forced convection, like natural convection in regular solar-air dual-source heat pumps, extracts ...Den vollständigen Artikel lesen ...
