Abstract
A method of controlling an absorption type refrigerating apparatus comprising detecting the temperature of the regenerator, limiting the amount of heating in the regenerator for a first predetermined time after the temperature of the regenerator reaches a predetermined temperature, controlling the amount of heating in the regenerator in accordance with a load when the temperature of the regenerator after the passage of the first predetermined time is lower than the predetermined temperature, abnormally suspending the regenerator by distinguishing a normal rise in the temperature of the regenerator caused by a load fluctuation from a rise in the temperature of the regenerator caused by leakage in the apparatus or the like when the temperature of the regenerator reaches the predetermined temperature within a second predetermined time after the passage of the first predetermined time, thereby avoiding repetitions of operation, suspension or limited operation of the regenerator and suppressing the corrosion of the regenerator.
