Abstract
An automotive air conditioning system is provided to be able to minutely control the air blow temperature independently of the ambient temperature to maintain the compartment always pleasant. The difference between the revolution speed of a compressor with a temperature setting lever for setting the revolution speed of the compressor set in the left end position and the revolution speed of the compressor with the temperature setting lever set in the left end position is increased in the mid summer or mid winter and reduced in the spring or autumn, whereby the air blow temperature can be minutely controlled to make the inside of the compartment always pleasant.
Claims14
An automotive air conditioning system comprising:
- an air blowing means for generating air flow;
- an air flow passage for introducing air from the air blowing means;
- a heat exchanger provided within the air flow passage for cooling or heating the air;
- a compressor composing a refrigerating cycle with the heat exchanger and driven by a driving power supplied from an external driving power source;
- a temperature setting means for setting a temperature of air blown out from the air flow passage into a compartment within a range from a minimum temperature to a maximum temperature;
- a revolution speed controlling means for controlling a revolution speed of the compressor based on a setting value set by the temperature setting means;
- an ambient temperature detecting means for detecting a temperature of outdoor air;
- and
- a revolution speed regulating means for regulating a first revolution speed of the compressor when the temperature setting means is set to the minimum temperature and a second revolution speed of the compressor when the temperature setting means is set to the maximum temperature based on an ambient temperature detected by the ambient temperature detecting means.
