Abstract

In the current research, studied experimentally of a solar air collector was conducted using latent thermal storage (wax of paraffin), in which energy of solar is collected during the time day, and released after sunset. Experimental studies were conducted under the Climate of Iraq - Baghdad (longitude 44.4 degrees east and latitude 33.34 degrees north). At various rates of mass flow air 0.027 kg / s, 0.03255 kg / s, and 0.038 kg / s in winter 2020 and on clear days, measurements and experimental work were conducted. The experimental findings indicated that the speed of paraffin wax melting is reversely proportional to the rate of mass flow of air. In m=0.038kg/s, the maximum heat gain value occurs. An increase in the rate of air mass flow decreases heat storage time.
