があった。(C) Problem to be Solved by the Invention In the above-mentioned conventional technique, in order to double the capacity of the absorption refrigerator, for example, an absorption refrigerator in which two evaporative absorber cylinders are connected in parallel by piping is conceivable. During operation of the absorption refrigerator thus configured, the refrigerant liquid level of the refrigerant liquid reservoir of the evaporator provided on one of the evaporation absorber cylinders and the refrigerant liquid reservoir of the evaporator provided on the other evaporation absorber cylinder When a difference occurs between the refrigerant liquid level and the refrigerant liquid level, the hydraulic head pressure applied to the refrigerant liquid pumps provided in the refrigerant circulation pipes of the respective evaporators also becomes different. Therefore, a difference occurs in the amount of the refrigerant liquid sprinkled on each evaporator,
There is a possibility that a difference may occur in the temperature of the cooling water cooled in each evaporator.

There is In addition, the amount of refrigerant sprayed in the evaporator is greatly reduced, the cold water cooling capacity of the evaporator is reduced, and the difference in the temperature of the cold water flowing out from each of the evaporation absorber cylinders is increased.

ションが発生する。Further, when a difference occurs in the absorption liquid level of the absorption liquid reservoirs formed in the respective evaporative absorber cylinders, a difference occurs in the rare absorption liquid discharge amount of the absorption liquid pump connected to each absorption liquid reservoir. . Therefore, the amount of rare absorbent flowing from each evaporative absorber cylinder to the generator is significantly different, and the amount of heat exchange between the rare absorbent and the concentrated liquid sprayed to each absorber also changes, resulting in There may be a difference in the refrigerant absorption capacity, which may cause a large difference in the cooling capacity of the cold water. Further, when the amount of absorption liquid in one of the absorption liquid reservoirs is greatly reduced, cavitation occurs in the absorption liquid pump.
