Résumé

A dual heat pump/air conditioning system for automotive applications is presented in this article. There is a continuing problem with the heating systems in most cars due to the inadequate heat available during the initial engine warm-up period, especially in cold weather. A dual heat pump/air conditioning system may be designed for cars, so that the passenger cabin is heated shortly after engine start-up in winter condition. The proposed dual system design has the potential to overcome the delayed heating problem. Furthermore, by using special valves it is possible to switch between the heating and cooling modes for appropriate outdoor conditions. The results of the extensive testing of the proposed system showed that the heat pump coefficient of performance varied between 2.0 and 5.0 depending on the outdoor air conditions. It appears that with the system optimization the heat pump would be viable for automotive applications.
