Vehicle air conditioning system for motor vehicle, has hybrid heat exchanger that is thermally conductively connected to refrigerant and heating circuits, while temperature level of heat transfer mediums flown is adjusted by leads

摘要

The system (10) has a heat exchanger (1) that supplies air to the interior of vehicle. The heat exchanger is designed as hybrid heat exchanger which is thermally conductively connected to refrigerant circuit (6) including fluid radiator (7), and heating circuit (8) including fluid heater (9). The temperature level of heat transfer mediums flown through return line (25) is adjusted by leads (14,15), so as to optionally heat differently tempered heat transfer mediums for heating and cooling purposes. The heat transfer medium is mixture of water and glycol.
