ABSTRACT:
To eliminate great increases in regeneration temperature and pressure and prevent the stoppage of an absorption refrigerating apparatus for safety upon a rise in the temperature of cooling water as well as to prevent crystallization and reduce fuel costs upon a reduction in the temperature of cooling water, the absorption refrigerating apparatus comprises a controller 34 which is constituted such that the opening of a fuel control valve 21 is controlled to a range of 0 to 100% to control the amount of heating in a high-temperature regenerator 1 when the inlet temperature T2 of cooling water is between a variable low-temperature set value and a variable high-temperature set value.
