PURPOSE:To enable to deal with a trouble immediately upon stopping due to the trouble by a method wherein the detected values of the operating conditions of the equipment are memorized into a micro-computer with a given time interval and are indicated on an indicating board upon the rouble which is caused in the equipment. CONSTITUTION:A indicating board 1 is connected to a micro-computer 2. An integrated electric power detector 3, a current detector 4, a motor operating hours detector 5, a motor surface temperature detector 6, a refrigerant pressure detector 7, a dust removing filter differential pressure detector 8, a cooling water inlet temperature detector 9, a cooling water outlet temperature detector 10, a blowing air temperature detector 11, a suction air temperature detector 12, a water leakage detector 13 and a timer 14 are connected to the micro-computer 2. The outputs of respective detectors are memorized into the micro-computer 2 with a given time intervals and when a trouble is caused in the equipment, the detected values of respective detectors immediately before or upon troubling of the troubled equipment are indicated on the indicating board. |
