に付加して表示手段に表示される。(Function) Since the present invention has the above configuration, while the refrigeration system is in operation, operating information indicating the operating state and failure information are input to the storage means and stored therein together with the calendar time. Then, according to a command from the command means, the date and time when the failure occurred and the operating information at that time are added to the failure information and displayed on the display means.

（実施例） 本発明の１実施例が第１図に示されている。(Example) One embodiment of the invention is shown in FIG.

冷凍装置の運転中、その運転状態を示す運転情報、例え
