Solar space cooling appears to be very attractive for low temperature grain storage because the pattern of availability of solar energy matches the demand for cooling. In this study, a novel solar-powered adsorption chiller was developed and put into experimental operation used for low temperature grain storage. Test results show that the solar-powered adsorption chiller can produce a cooling capacity about 66 to 90W per m² collector area. Its daily solar cooling COP (coefficient of performance) is about 0.1 to o.13 under the climatic conditions of daily solar radiation being about 16 to 21MJ/m²·day. With appropriate ventilation appliance, this kind of solar-powered adsorption chiller could be considered as an alternative for low temperature grain storage in most areas of China.
