A FIELD EXPERIMENT ON HEAT ACCUMULATION OF SOLAR PONDS BY LOW CONCENTRATION SALT WATER

Abstract

A field experiment on the heat accumulation of solar ponds was carried out using low concentration salt water. The solar pond system exhibited certain heat accumulation, by being taken the special measures, in a relatively short period (1-3 weeks). The temperature in the lower layer was about 6°C higher than that in the upper layer, in addition, maximally about 15°C higher than the air temperature in the night-time. The accumulated heat in the lower layer of the solar pond could be used for heating relatively narrow spaces, for example, rooms in general houses and greenhouses in farms.
