An Experimental Investigation of Free Space Cooling by Phase Change Material (PCM)

In free space cooling PCM at suitable melting point is solidified by using night time cold air. During day time room air is passed over the solid PCM which absorbs Latent heat from it and melts. As a result room air gets cooled. In the present work suitable double pipe heat exchanger is designed and...
