Abstract
In order to provide a control apparatus for an air conditioning system for an electric vehicle which achieves smooth switching of operating modes, a decision is made as to whether or not the operating mode set by a means for air conditioning mode setting has been maintained for a specific length of time and also, a decision is made by a means for compressor rotation rate decision making as to whether or not the actual rotation rate of the compressor is at the minimum rotation rate. With this, if the operating mode set by the means for air conditioning mode setting has not been maintained for the specific length of time, or, if the operating mode has been maintained for the specific length of time but the actual rotation rate of the compressor is not at the minimum, the rotation rate of the compressor is set at the minimum rate by a means for shift mode setting so that the operating mode is switched only when the operating mode set by the means for air conditioning mode setting has been maintained for the specific length of time and the actual rotation rate of the compressor is at the minimum rate, and the compressor is controlled based upon the air conditioning level set by the means for air conditioning mode setting.
