TRIPLE EFFECT ABSORPTION TYPE REFRIGERATOR

PROBLEM TO BE SOLVED: To operate a double effect absorption type refrigerator at the time of a maximum load in midsummer by constituting to extract a part or all of vapor generated in a high temperature regenerator to an intermediate temperature regenerator via a bypass passage in the case of a high temperature and a high load of cooling water in midsummer or the like. SOLUTION: In the triple effect absorption type refrigerator comprising an evaporator 1, an absorber 2, a condenser 15, low temperature, intermediate temperature and high temperature regenerators 7, 8 and 9, low temperature, intermediate temperature and high temperature heat exchangers 6, 20, and 19 provided on the way of the pipings communicating with each other, a bypass passage 21 for supplying vapor generated from the regenerator 9 to a shell side of the regenerator 8 is provided. In the case of a high cooling water temperature at one time in midsummer, a part or all of the vapor generated from the regenerator 9 is bypassed to the regenerator 8. Thus, a pressure, a temperature of the regenerator 9 during operating are suppressed to those of a double effect absorption type refrigerator. Meanwhile, in an intermediate season or the like, the passage 21 is closed, and a high efficiency operation of the triple effect is intended.
