A method and apparatus for conserving the amount of energy used to drive an absorption refrigeration generator while concomitantly insuring satisfaction of system load demands. The system includes an absorption refrigeration generator having a concentrator section, a condenser section, an evaporator section and an absorber section wherein a heating medium, such as steam, is circulated through the concentrator section to vaporize refrigerant within the system and a closed loop, chilled water, heat exchange system is used to transfer cooling potential from the evaporator section to the system load, such as an office building. Control of the energy delivered to the concentrator for liberating refrigerant and thus providing cooling in the evaporator is achieved by sensing the temperature of the chilled water as it returns from the cooling load and modulating energy input to the concentrator to maintain a generally constant set temperature of the return chilled water.
