<p>PURPOSE:To control indoor temperature with less responding time by obtaining a temperature gradient by a thermal sensor provided in a housing to predict a temperature rising amount, and generating a cooling control command responsive thereto to control a cooler. CONSTITUTION:A thermal sensor 4 is disposed in the rear stage of a section 1 to be cooled to detect the temperature of cooling air 9. A controller 5 obtains temperature detected by the thermal sensor 4 at each predetermined time by a contained timer, calculates a temperature gradient from the obtained temperature, and applies it as a cooling control command based on preset temperature- cooling amount data in response to the temperature gradient to a cool controller 6. The cool controller 6 applies the command as a cooler control signal for inverter-controlling the rotating speed of the motor of a cooler 2. Accordingly, in the cooler 2, the rotating speed of the motor is varied according to the cooler control signal applied from the cool controller 6, provides cooling air 7 responsive to the temperature gradient, controls the temperature in the housing for a small responding time, and delicately monitors the temperature.</p> |
