Claims (1)
、ヒータと、同熱交換器からの吹き出し空気温度
を検出する吹出温度検知器と、前記熱交換器への
戻り空気温度を検出する吸込温度検知器を備え、
設定温度に応じて選択された前記吹出温度検知器
又は吸込温度検知器の検出温度が前記設定温度と
なるよう運転制御する冷凍装置の制御装置におい
て、前記温度検知器の検出温度が冷凍装置として
あり得ない上下限検出温度範囲外を異常とみなす
第１異常検出手段と、冷凍装置の運転時間計時手
段を設け、所定時間運転を実施後の前記吹出温度
検知器と吸込温度検知器の検出温度差が所定範囲
外の場合は、前記温度検知器のいずれかが異常で

徴とする冷凍装置の制御装置。 A heat exchanger, blower, and heater that cool or heat the air inside the refrigerator, a blowout temperature detector that detects the temperature of the air blown out from the heat exchanger, and a suction temperature sensor that detects the temperature of the air returned to the heat exchanger. Equipped with a vessel,
In a control device for a refrigeration equipment that controls operation so that a temperature detected by the outlet temperature detector or a suction temperature detector selected according to a set temperature becomes the set temperature, the temperature detected by the temperature sensor is set as the refrigeration equipment. A first abnormality detecting means that considers a temperature outside the upper and lower limit detection temperature range to be abnormal, and a means for measuring the operating time of the refrigeration equipment, and detecting a temperature difference between the outlet temperature detector and the suction temperature detector after the operation has been carried out for a predetermined period of time. A control device for a refrigeration system, characterized in that a second abnormality detection means deems that one of the temperature detectors is abnormal when the temperature is outside a predetermined range, and a display means for informing the content of the abnormality when an abnormality occurs. .
