<p>A method for controlling an electric compressor into which an inverter for controlling an electric motor as a drive source is integrally incorporated. The method is characterized by comprising the steps of acquiring the temperature of an accessory of the inverter, when the acquired temperature becomes or is already equal to or higher than the maximum rated temperature of the accessory, calculating the value of a current which can flow at the acquired temperature and restrictively controlling the rotational speed of the electric compressor such that the input current becomes equal to or less than the value of the current which can flow, and when the temperature of the accessory becomes lower than the maximum rated temperature, releasing the restrictive control. The method for controlling the electric compressor can prevent a malfunction of the accessory even in use under a high-temperature environment while preventing increase in the cost and size of the electric compressor by preventing an increase in the size of the accessory of the inverter.</p> |
