Thompson, T. L.

Data were collected from an adobe building in Tucson with a metal roof to evaluate residential cooling by nocturnal radiation. Experimental results were correlated by an equation similar to that used to describe solar collector performance, relating the heat rejection rate (-q/sub u/), to the net radiation term (R), the inlet fluid (t/sub fl/) and ambient air temperature (t/sub a/), using a plate efficiency factor (F/sub R/) and heat loss coefficient (U/sub L/). Cooling by nocturnal radiation alone was found to be inadequate during peak summer cooling periods. The results were extrapolated to the case of evaporative cooling using a wetted roof; heat rejection from the wet roof appears adequate for residental cooling in a hot, arid climate.
