Abstract
According to the present invention, when the inside air circulation mode is determined, the blower for blowing air to the heat exchanger is operated with the regular blower voltage. When the outside air introduction mode is determined, the blower is operated with the lower blower voltage lower than the regular blower voltage. As a result, consumed electric power of a compressor in the outside air introduction mode can be controlled and the deterioration of the efficiency of the refrigerating cycle in the inside air circulation mode can be prevented.
Claims19
An air conditioning apparatus for a vehicle having a passenger compartment, said air conditioning apparatus comprising:
- a casing having an air passage in which an inside air inlet for sucking air and an outside air inlet for sucking outside air are formed at one end and an air outlet for blowing out air into a passenger compartment is formed at the other end;
- air inlet opening/closing means for selectively opening and closing said inside air inlet and said outside air inlet in such a manner that an inside air circulation mode where said inside air inlet is opened and said outside air inlet is closed or an outside air introduction mode where said outside air inlet is opened and said inside air inlet is closed is selectively set;
- a heat exchanger provided in said air passage for heat exchanging with air in said air passage, a capacity of said heat exchanger being electrically controlled;
- air blowing means for generating air flow within the air passage from said inside air inlet or said outside air inlet to said air outlet;
- inside/outside air switching mode determining means for determining whether said air inlet opening/closing means is in said inside air circulation mode or in said outside air introduction mode;
- first air flow controlling means for controlling said air blowing means in such a manner that an air amount by said air blowing means is set to a first air amount when said inside air circulation mode is determined by said inside/outside air switching mode determining means;
- and
- second air flow controlling means for controlling said air blowing means in such a manner that said air amount by said air blowing means is set to a second air amount which is lower than said first air amount when said outside introduction mode is determined by said inside/outside air switching mode determining means.

- air blowing means for generating air flow within the air passage from said inside air inlet or said outside air inlet to said air outlet;
- inside/outside air switching mode determining means for determining whether said air inlet opening/closing means is in said inside air circulation mode or in said outside air introduction mode;
- air flow controlling means for controlling said air blowing means in such a manner that an air amount by said air blowing means is set to a first air amount when said inside air circulation mode is determined by said inside/outside air switching mode determining means;
- and
- air amount changing means for controlling said air blowing means in such a manner that said first air amount is changed to a second air amount which is lower than said first air amount when said outside introduction mode is determined by said inside/outside air switching mode determining means.
