摘要： PROBLEM TO BE SOLVED: To efficiently utilize a whole heat transfer surface of a heat exchanger by setting a predetermined period of time when a cooling pump for flowing cooling water into the heat exchanger of an evaporator is not started after a cooling-water pump, a solution pump and a heating source of a high temperature regenerator having been started. SOLUTION: Cooling operation starting signals are inputted to a control unit 17 to start a cooling pump, and in a state where the temperature of cooling water is stabilizer, the temperature thereof is detected by means of a cooling water temperature detector 12. The detected cooling water temperature is compared with a preset temperature so as to judge whether or not the detected temperature falls within the range of cooling requirements. When judged as being in the range of the cooling requirements, the cooling pump is stopped for a given time, and a cooling-water pump 14 is started. Subsequently, a liquid pump 9 is started to spray refrigerant in a refrigerant tank 11 to a heat exchanger 4a in an evaporator 4. Then, operation of a solution pump 8 and heating a solution by a heating source 1a in a high temperature regenerator 1 are started. After lapse of the given time, the cooling pump is restarted for a normal operation.

摘要： PURPOSE:To prevent cavitation due to a decrease in a static pressure and circulation failure, generation of noise due to the cavitation by installing a pump mechanism to be driven by utilizing flow of solution from a high temperature regenerator to an absorber on a regenerated solution input route, and feeding the solution from the regenerator to the absorber. CONSTITUTION:At the time of heating, solution is heated to be boiled by a burner 11 in a high-temperature regenerator 1. Generated refrigerant vapor is pressure-reduced by a valve 31, then introduced to an evaporator 4, and condensed on an evaporating heat transfer tube 30 to heat heating warm water flowing in a tube. On the other hand, concentrated solution in the regenerator 1 is heat exchanged with solution from an absorber 5 by a high-temperature heat exchanger 10 to be cooled, and solution from a low-temperature regenerator 2 is sucked by a concentrated solution jet pump 8 which utilizes a loss head of a solution scattering unit 14 in the absorber 5 and a height head to the unit 14. The mixed solution in this case is heat exchanged with dilute solution from the absorber 5 in a low-temperature heat exchanger 9 to be further cooled, and then fed to the unit 14.
