Abstract

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.
