ABSTRACT

This Project work is the Analysis of a Modified Single Effect  Solar Vapour Powewred Absorption Refrigeration System. The System is designed to accommodate 2 Heat Exchangers, a Solar collector that absorbs solar energy from the sun rays through the help of photovoltaic cells, a Generator which Converts or transforms the solar energy to heat energy released into the system, a condenser, an evaporator, 2 expansion valve, a pump. All these components are incorporated to help reduce the effect of the heat energy by declining the high temperature of the system which initial was identified to be 40^OC to achieve a temperature of about 5^OC by addition of a heat exchanger to the evaporator compartment which maintained this temperature and provided optimum level of coefficient of performance. This is basically why 2 heat exchangers were used in the system instead of one because of this effect, this System aims also to increase the coefficient of performance to 0.612 which is noted to be an improvement in the refrigerating effect compared to other counterparts of the system developed in region. The overall result of the system will increase the cooling capacity of the refrigerant and the coefficient of performance to the optimum. Even if variable temperature is considered it will give the most suitable temperature to achieve the optimum cooling capacity under adverse environmental conditions. An increase in the Temperature of the Generator will result in increase in the COP and the cooling capacity at reduced absorber temperature.
