Abstract
An object of the present invention is to reduce electrical noise in accordance with the necessity of a countermeasure taken against electrical noise without changing a structure of an expansion valve. In a case where a judgment result as to whether or not the countermeasure against electrical noise is taken is affirmative, a drive timing (interval) of an expansion valve () is increased. Further, a driving amount is reduced. Accordingly, a flow of a refrigerant is made slow, whereby it is possible to reduce generated electrical noise while performing instructed temperature control.
