PURPOSE:To enable to perform energy saving cooling operation, by so constituting that a signal increasing a given temperature by an arbitrary value becomes applicable when illuminance detected by a photodetector becomes lower than the arbitrarily set level. CONSTITUTION:A signal is applied to a control part 4 when illuminance of sunlight sensed by a photodetector 1 becomes lower than the arbitrary illuminance and upon receipt of the signal by the control part 4 a signal raising a given temperature by an arbitrary value DELTAT deg.C is applied to a room temperature adjuster 3 by the control part 4, in the title operation controller consisting of a room temperature detector 2, the room temperature adjuster 3, the control part 4 and a relay output part 5 for a compressor. A signal is applied to a relay output part 5 from the control part 4 due to a relation between the room temperature detected by the detector 2 and the given temperature which has been raised by DELTAT deg.C. With this construction, an operation factor of the compressor is reduced and far more energy saving cooling operation can be performed. |
