Solar powered adsorption refrigeration systems have been preserved the food for the national requirement and also protected the environment. In this research article, the design and development of semi-continuous solar powered Adsorption water chiller for food preservation are presented. The design of the main components includes an adsorber bed, a condenser, an expansion device and an evaporator are performed by using heat transfer correlations. The outcomes of design are presented and discussed. The cooling produced in 10 kg of water was 554 kJ in 6 hours for the water flow of 170 kg/hour, 25° C condenser temperature and 65° C adsorber temperature.The fluctuation in system pressure is observed in the range of 30 kPa to 80 kPa for desorption and adsorption process during experimentation. The chiller performance was tested and compared with the earlier adsorption chiller. The comparison showed that proposed chiller has higher specific cooling power (SCP), low cycle time and low generation temperature due to activated carbon fiber-methanol pair and effective design of the system.
