Vehicle air conditioning system has a heat shield at the inflow side of the heater, to prevent heat affecting cooled air flows for a more efficient operation

摘要

The air conditioning unit (10), especially for a vehicle, has an air feed housing (12) and a cooling heat exchanger (18) which is in a cooling circuit to reduce the air temperature. A heater (20) heats the air. A control sets the required air flows. A heat shield (44) is at the air inflow side of the heater to prevent heat acting on the cooled air flow.
