In recent year engineers are trying to improve system which will be energy/fuel efficient. Part of this is to focus on waste kinetic energy generated from current existing systems. Because of that regenerative suspension system is getting lot of attention. The idea is to use energy generated in suspension and cultivate it in other energy forms. In last few years necessity for ecofriendly Air-conditioning system is increasing due to increase in pollution. The focus of this paper is to prove that the waste kinetic energy which gets stored in suspension system as result of ‘to and fro’ motion while driving vehicle can be utilize and this energy can be used as thermal power for Air-conditioner. As the result the power required for Air-Conditioning system will be reduce causing in saving of fuel and reduction in the emission of carbon pollutant. The system presented in this paper is analogous to the suspension system of vehicle and it will demonstrate the conservation of supplied energy by using various components. The goal of the system is to gain maximum temperature difference of 4ºC which can be maximize in future research.  In order to provide the proof of the system analytical calculation has been provided for component selection according to the required function and while doing that it is also considered that system should be compact and portable so that it will be easy for future installation. For different parts of the system material selection is particularly carried out by the based on the function of the part.  To achieve proper system step by step problem solving approach and failure analysis or considerations was studied and appropriate actions was taken for every single part.  The CAD model is provided with help of SolidWorks with the proper dimensions. The dimension of the parts are obtained from manufacturer. Based on this model Back-up proof for theatrical calculation is provided with the help of ANSYS Workbench by using tools of FEA and CFD (Fluent) which differs for critical parts. By using this tools the comparison is provided between actual system and theoretical system. The analysis tools was chosen based on the specific part and its function. The end results of this system are provided by using thermal sensors. The results obtained by sensors will used for future improvement of the system. More importantly based on this results it will be possible to determine the possible conversion of waste kinetic energy into thermal energy.
