Solar power air conditioning

Abstract

The purpose of this study is to introduce a new idea called "Solar Air Conditioning system". The concentration of greenhouse gases is rising, and the prices of gasoline and oils are in constant increase; therefore, a solution must be applied to avoid a major crisis. Solar air conditioning uses a free source of heat, the sun, to cool a space with a significantly minimal amount of consumption. This report starts with a brief introduction about "Refrigeration processes" then go along describing "Solar air conditioning processes" in its different forms, details and functions, to introduce the idea, and allows the reader to know what it is. The report focuses on the solar air-conditioning based on absorption cycle and the vapor-compression cycle; it discusses its main function and parts, and explains thermodynamics conditions for further understandings. A case study is developed and sample calculations are made on a car that operates in Lebanon to find the total cooling load needed due to the, glass and ceiling heat exchange. The cooling load turns out to be about 1002W. Two systems are then suggested: the conventional compression system in the car and the cooling system using the absorption cycle. The case study, and after many calculations performed, shows that an amount of 1781 {dollar} will be saved along 5 years once the air-conditioning system is integrated into a solar system.
