| ABSTRACT |
|
The aim of this paper is to investigate the possibility of using an R-134a heat pump system with a conventional air-conditioning system for zero-emission vehicles. A heat pump system is one solution to heating the cabin and defrosting the windshield while consuming little energy. The system components consist of an internal heat exchanger, external heat exchanger, electrically driven compressor, electric expansion valve, and refrigerant flow change valves. Cooling capacity was examined by varying vehicle driving conditions and the compressor |
