Title: A theoretical model for an open system with sky radiation cooling and solar radiation

Abstract

Since the atmosphere of the earth is relatively transparent in the infrared (i.r.) wave length region between 8 and 13 {mu}m, what the authors call the atmospheric window, a part of the thermal radiation at the surface of the earth is lost into space and cooling takes place. This phenomenon is referred to as sky radiation cooling. In this paper, the combined heat transfer simulation was performed for a water reservoir undergoing sky radiation cooling as well as solar radiation, evaporation, convective heat transfer and heat conduction to the soil. Examples of applications considered here are warming of rice field water, swimming pools, breeding reservoirs, and solar ponds. The present study will provide good information to cope with the unusual cold weather experienced during the summer of 1993 in Japan. According to the present analysis, the water temperature of a rice field can be considerably raised and, as a result, a bad harvest avoided.
