る。DETAILED DESCRIPTION OF THE INVENTION (a) Industrial Application Field The present invention relates to an absorption refrigerator, and particularly to an absorption refrigerator equipped with a plurality of evaporators or absorbers. B) Prior art For example, Japanese Utility Model Publication No. 58-44297 discloses an absorption refrigerator in which an evaporator is arranged in the center of an evaporator-absorber body, and absorbers are arranged on both sides of the evaporator. During operation of the absorption refrigerator, the refrigerant liquid sprayed in the evaporator is vaporized, and the refrigerant vapor is absorbed by the concentrated absorption liquid sprayed in the absorber.

た冷媒液ポンプに加わる木頭圧にも差が生じる。(c) Problems to be Solved by the Invention In the above-mentioned conventional technology, the capacity of the absorption refrigerator is
In order to double the capacity, an absorption refrigerating machine with two evaporator cylinders connected in parallel via piping may be considered. During operation of an absorption chiller configured as described above, the refrigerant level in the evaporator refrigerant reservoir provided in one evaporator-absorber shell and the evaporator refrigerant reservoir provided in the other evaporator-absorber shell are determined. When a difference occurs in the refrigerant liquid level of the evaporator, a difference also occurs in the head pressure applied to the refrigerant liquid pump provided in the refrigerant circulation pipe of each evaporator.
このため、各蒸発器に散布される冷媒液の量に差が生じ
て、各蒸発器にて冷却された冷却水の温度に差が生じる
虞れがあった。For this reason, there was a possibility that a difference would occur in the amount of refrigerant liquid sprayed to each evaporator, and a difference would occur in the temperature of the cooling water cooled in each evaporator.

る。Additionally, if the amount of refrigerant in either refrigerant reservoir decreases significantly and the refrigerant level drops to the level of the refrigerant pump, cavitation may occur in the refrigerant pump and there is a risk that the refrigerant pump may malfunction. There is. Moreover, the amount of refrigerant sprayed in the evaporator is significantly reduced, the chilled water cooling capacity of the evaporator is reduced, and the difference in temperature of the chilled water flowing out from each evaporator-absorber shell becomes large.

ゴンが発生する。Furthermore, if there is a difference in the absorption liquid levels in the absorption liquid reservoirs formed in each evaporator-absorber body, there will be a difference in the amount of diluted absorption liquid discharged by the absorption liquid pumps connected to each absorption liquid reservoir by piping. ．． For this reason, the amount of diluted absorbent flowing from each evaporator-absorber shell to the generator differs greatly, and the amount of heat exchanged between the diluted absorbent and the concentrated liquid sprayed to each absorber also changes. There is a possibility that a difference will occur in the refrigerant absorption capacity, and a large difference will occur in the cooling ability of the chilled water. Furthermore, if the amount of absorption liquid in one of the absorption liquid reservoirs decreases significantly, cavitation occurs in the absorption liquid pump.

凍機の成績係数を向上させることが可能になる．Furthermore, since connecting pipes are connected between the absorbent reservoirs formed in each of the plurality of evaporator-absorber shells, the difference in temperature of the cooling water flowing through the absorber of each evaporator-absorber shell or the concentration of liquid in each absorber can be prevented. If there is a difference in the absorption liquid level in each absorption liquid reservoir due to a difference in the amount of spraying, the absorption liquid in the absorption liquid reservoir flows through the above-mentioned communication pipe, and the absorption liquid concentration in each refrigerant liquid reservoir is kept approximately equal. This allows the absorption liquid level in each absorption liquid reservoir to be maintained approximately equal, thereby avoiding the occurrence of cavitation in the absorption liquid pump due to a significant drop in the absorption liquid level in one absorption liquid reservoir. This greatly simplifies the maintenance of the absorption pump. In addition, if one of the absorption liquid pumps in each evaporator barrel breaks down, the absorption liquid will flow between each absorption liquid reservoir through the connecting pipe, and the absorption liquid will rise due to the absorption liquid level rising. can be avoided from mixing with the refrigerant liquid. Furthermore, by providing an on-off valve in the communication pipe connected between the refrigerant liquid reservoirs of each evaporator-absorber shell, and by providing an on-off valve in the communication pipe connected between the absorption liquid reservoirs, it is possible to When only the evaporator-absorber shell is operated, the on-off valve is closed, and it is possible to avoid wasteful flow of refrigerant liquid or absorption liquid to the evaporator-absorber shell that is not in operation, and as a result, the coefficient of performance of the absorption chiller is reduced. It becomes possible to improve.
