A Heat-Pump Air Conditioner based on Waste Heat Recovery Strategy for Hybrid Vehicles

Abstract

How to improve fuel range and efficiency is one of most important targets for hybrid Vehicles. As one solution, heat-Pump air conditioner has more advantages than traditional air conditioner, such as high heating efficiency and range extension. A new Heat-Pump air conditioner based on waste heat recovery strategy is presented in this paper. A heat exchanger between engine circuit and air conditioner circuit provides waste heat recovery. The new structure is built and simulated on a software-in-loop platform, which is based on KULI and Matlab/Simulink. Simulation results indicate that platform provide us higher COP (Coefficient of Performance) and rapid response time.
