た。(c) Problems to be solved by the invention The above-mentioned conventional absorption refrigerator of this type uses a concentrated solution pump to promote the flow of concentrated solution and improve the efficiency of the solution heat exchanger. It has the advantage of improving the coefficient of performance and refrigeration performance. On the other hand, for example, if the temperature of the cooling water supplied to the aircraft during light loads becomes lower than normal,
The drawback is that the refrigerating capacity is excessive, which tends to cause various problems such as excessive cooling, freezing of the cold water and refrigerant, and crystallization of the solution. In addition, in the above-mentioned conventional system, by diluting the concentrated solution with a dilute solution in the mixing tank, excessive cooling during light loads can be alleviated to some extent, but there is a limit to the dilution of the concentrated solution with the dilute solution, so the above-mentioned There is a problem in that it is not possible to quickly and reliably prevent the adverse effects that tend to occur in cases such as these.

A controller that adjusts the discharge rate of the concentrated solution pump, and a flow that allows the concentrated solution to flow from the generator side to the absorber bypassing the solution heat exchanger even when the pump discharge rate has been reduced to near zero. This type of absorption refrigerating machine is equipped with a duct and a duct.

に防ぎ得る効果がもたらされる。(v) Function In this type of absorption refrigerator of the present invention, when the cooling fluid is not fully supplied into the machine under normal conditions, the concentrated solution pump operates to promote the flow of the concentrated solution.
As with conventional absorption refrigerators of this type, the efficiency of the solution heat exchanger and the refrigeration performance (heat pump performance) are improved. On the other hand, if the temperature of the cooling fluid that can be supplied into the machine drops excessively (for example, below 20°C), the discharge rate of the concentrated solution pump is reduced to nearly zero, and the high temperature concentrated solution from the generator side is used for solution heat exchange. Since the solution bypasses the reactor and directly flows into the absorber, the refrigerant absorption ability of the solution in the absorber and the effect of suppressing the temperature drop are exerted. This action provides the effect of reliably preventing excessive cooling, cold water, freezing of the refrigerant, and crystallization of the solution.

キャビテーションを生じる等、様々な弊害を引起す。Now, for example, if the outside temperature drops below the normal temperature and the temperature of the cooling water supplied to the machine drops to the lower limit set value [20'C or less], the cooler (28) of the absorber (7) As the temperature and vapor pressure of the concentrated solution sprayed on the evaporator (6) decrease, its refrigerant absorption capacity increases, and as a result, the amount of refrigerant vaporized in the evaporator (6) increases, the refrigeration output increases, and the evaporator (6) 5) The saturated temperature and saturated vapor pressure of the inside decrease. on the other hand,
As the outside temperature falls, the load on the cooling side becomes smaller. As a result, the air conditioner starts to become too cold. If this is left as is, the cold water and refrigerant in the evaporator (6) will cause an excessive temperature drop and freeze, or the absorber (7) will
The concentrated solution in the low-temperature solution heat exchanger (8) may crystallize due to an excessive temperature drop of the dilute solution flowing out from the evaporator (6), or the liquid reservoir may crystallize due to an increase in the amount of vaporized refrigerant in the evaporator (6). (3
6) The amount of liquid in the refrigerant pump (PR) decreases excessively, causing various problems such as cavitation of the refrigerant pump (PR).

The concentrated solution pump (P
, A) is reduced to near zero, so that most of the high temperature concentrated solution flowing out from the low temperature generator (3) bypasses the low temperature solution heat exchanger (8) and flows into the absorber (7). It flows in while still being hot. As a result, the temperature of the solution in the absorber (7) increases, and the saturated vapor pressure and saturated temperature in the evaporative absorber (5) increase. Therefore, freezing of the chilled water and refrigerant is reliably prevented, and the refrigerant absorption effect of the concentrated solution sprayed in the cooler (28) is also suppressed, reducing the amount of refrigerant vaporization and preventing the air conditioner from becoming too cold. , the excessive decrease in the amount of liquid in the liquid reservoir (36) is eliminated, and cavitation of the refrigerant liquid pump (PM) is also prevented.Furthermore, the temperature of the solution flowing out from the absorber (7) also rises, so the low temperature Crystallization of the solution in the solution heat exchanger (8) can also be prevented.

格の吐出量に戻される。Then, when the outside temperature starts to rise again and the temperature of the cooling water supplied to the machine exceeds the lower limit set value, the discharge amount of the concentrated solution pump (PHA) changes depending on the cooling water temperature.
), the increase can be adjusted via the controller (C), and efficient operation is restarted to promote the flow of the concentrated solution and increase the heat exchange of the low temperature solution heat exchanger (8), and the cooling water temperature is increased. The capacity of the absorber (7) is adjusted accordingly. Note that when the cooling water temperature rises to 30''C, the pump (PHA) returns to the rated discharge amount.
