Solar energy refrigeration is very attractive for low-temperature grain storage because the cooling load of low-temperature grain storage is roughly in phase with solar energy availability. In this study, a solar-powered adsorption chiller was developed with aim of developing an alternative refrigeration device for low-temperature grain storage. The solar-powered adsorption chiller was put into experimental operation during summer and autumn. Test results show that the solar-powered adsorption chiller can produce a cooling capacity about 66–90 W per m2collector area. Its daily solar-cooling COP (coefficient of performance) is about 0.1–0.13 under the climatic conditions of daily solar radiation being about 16–21 MJ/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.
