Heat pump supplemental heating system for motor vehicles

Abstract

The paper deals with the importance of supplemental heating of motor vehicles and the possibilities of automotive heat pump system utilization. A prototype heat pump system for motor vehicles has been developed, built in a test vehicle and tested at low-temperature working conditions. Results have been analysed and the system compared with the other current-production supplemental heating systems. The proposed automotive heat pump heating system has been found to be superior to other automotive supplemental heating solutions regarding the parameters of performance, fuel consumption and operational behaviour.
