Air conditioning system for motor vehicle, has temperature adjusting device adjusting control unit to target value of temperature of air in cabin, and external air portion controlled by control unit based on high pressure at compressor

摘要

The system (2) has a temperature adjusting device adjusting a control unit to a target value of temperature of internal air in a passenger cabin. A determining device (26) detects temperature and/or humidity of external air, internal air and supplied air. An inflow adjusting device adjusts an external air portion and an internal air portion of air supplied to an evaporator (14) by partially opening and closing an internal air-inflow opening (22) and/or external air-inflow opening (20). The external air portion is controlled by the control unit based on high pressure at a compressor (6). An independent claim is also included for a method for operating an air conditioning system.
