Abstract
The issue of global warming is getting more and more severe, and now it is of current interest in the world, including the issues of global warming and energy usage. Especially, in the high gasoline price today, it is much more important to reduce energy use and carbon than before. Thus, our project is to use the waste heat from car engines for driving absorption refrigeration system (ARS) to have waste heat recovery and energy saving. Our project use the waste heat of car engine exhaust which can reach 400℃-700℃. Therefore, if we can have car engines combined with ARS to use the heat recovery, we can reduce the use of energy and fuel. This project will establish a complete Car-ARS simulation and analysis system including COP parameters with experiments to correlate with test data. This project is to combine car engines with ARS. Using the high temperature of the engine exhaust, the output of cooling from ARS can be made. As a first step, with our car engine test facility in place, we need to obtain the simulated exhaust heat data at different operating points from the car engine in order to design a waste heat recovery system for the proposed ARS design. This will involve heat exchanger design and packaging. Secondly, we need to proceed to the ARS system with working fluid selection, fluid solution concentration design, mass flow rate calculations, and the whole system design. Finally, we will work with our participating company to work out the detail hardware selection, system design, and final packaging. Finally we estimate that the COP of ARS can be 0.46 and cooling capacity can be more than 2kW.
