Control for automobile air conditioning system

摘要

An automobile air conditioning system is provided with a control system for controlling the flow rate of hot or cool air discharged into the passenger compartment. The air flow rate is controlled in relation to the sensed value of the ambient air temperature and the temperature of a heat source of the air conditioning system. If the sensed temperatures are lower than predetermined reference levels, the air flow rate is gradually increased at a moderate increasing rate. The air flow rate is more rapidly increased when the sensed heat source temperature is higher than the reference level.
