Modification of Solar Peltier-Adsorption cooler has been done and fabricated during the Final Year Project. The main purpose of the project is to improve the performance of the Solar Peltier-Adsorption cooler. The device is using solar radiant to produce power from photovoltaic panel for generating the thermoelectric device in the daylight. Then, the device using adsorption and desorption theory to generate cooling effect during the night time. The device consists of a few main parts assembly which is solar collector, adsorber box, condenser, reservoir, evaporator and support frame. Solar flat plate collector type has been used for the system which can support an adsorber bed charcoal capacity of 5 kg. The adsorption cycle operates intermittently where provide only one cycle per day. The cooling effect occurs during the adsorption process at night. Photovoltaic panel provides electricity to peltier cooler to produce cooling effect during the day time. Therefore the cooling effect of the hybrid device can produce cooling effect continuously for day and night time period. Experimental results show that lowest temperature achieves is 9.3˚C in Peltier during daylight and 13.6˚C during the night by using 300ml load of water.
