蒸発器だけでは、製氷量が不足する問題が生ずる。(Problems to be Solved by the Invention) In the conventional example described above, a single ice making evaporator including a pair of an inner tube (A) and an outer tube (B) is used, and a plurality of fan coils are used. Slurry ice used in the units (F 1 ) to (F 4 ) is generated, but in a building air conditioner in which the number of installed fan coil units (F 1 ) to (F 4 ) is large, The amount of ice used increases, and a problem arises that the amount of ice making is insufficient with only one evaporator for ice making.
しかして、製氷量を使用量に対応して多くする場合、
１台の製氷用蒸発器を大形とするにも限界があることか
ら、複数台の製氷用蒸発器を用いる必要がある。However, if the amount of ice making is increased in accordance with the amount used,
Since there is a limit in increasing the size of one ice making evaporator, it is necessary to use a plurality of ice making evaporators.

氷用蒸発器を用いる必要が生ずるのである。That is, in order to increase the ice making amount in the ice evaporator having the above-described configuration, it is conceivable to increase the diameter or length of the inner tube (A) and the outer tube (B). Considering a decrease in ice making performance, an increase in the motor load for driving the drum (D), and the like, there is naturally a limit, and it is not possible to cope with an increase in the amount of use, and inevitably use a plurality of ice evaporators. The need arises.

溶液が流れるように溶液配管（18）を接続している。Further, in the first embodiment, the ice making tubes (2) arranged vertically in a superposed manner are made into one set, and in each of these sets, a series is formed in series from the lower ice making tube (2) to the upper ice making tube (2). The solution piping (18) is connected so that the ice making solution flows.

A connecting pipe (18b) is connected to the solution inlet (2a) of the upper and lower ice making tubes (2), and a solution outlet pipe (18c) extending to the heat storage tank is connected to the solution outlet (2b) of the upper ice making tube (2).

である。Thus, in order to make ice by the ice making device having the above-described configuration, a liquid refrigerant is supplied from the liquid refrigerant pipe (3) into the body (1), and a solution inserted into the solution inlet pipe (18a). A pump (not shown) is driven to cause the solution to flow through each ice making tube (2) through the above-described path, and drives the motors (12) and (13) to rotate the rotary blade (8). The height of the liquid refrigerant in the body (1) is controlled so that the lower half of the upper ice tube (2) is immersed in the liquid, as shown in FIG. It is.

（８）で掻取りスラリー状の氷を生成するのである。The liquid refrigerant supplied into the body (1) exchanges heat with the ice making solution flowing in the ice making pipe (2) and evaporates, and the latent heat of evaporation causes the wall surface of the ice making pipe (2) to evaporate. The solution is supercooled to a temperature below the freezing point, and the solution is frozen on the inner wall surface of the ice making tube (2). The frozen ice is scraped by the rotating blades (8) to produce slurry ice.

るのである。Therefore, the temperature of the inner wall of each of the ice making tubes (2) can be made substantially uniform while the solution is flowed in series to each of the ice making tubes (2), and the ice generation in each of the ice making tubes (2) can be made uniform. Yes, an increase in motor load due to ice formation spots can be avoided.

るのである。In addition, the liquid level of the liquid refrigerant may be controlled by controlling the liquid level in the body (1), and individual control is not required. Therefore, the control system can be simplified. Since the upper part of (1) can be used as a gas chamber,
The liquid refrigerant can be prevented from flowing out from the refrigerant outlet (1b), and the accumulator can be reduced in size or can be omitted.

の氷生成を均一にできるのである。As described above, the present invention provides holding members (5) and (6) on both sides in the longitudinal direction of a body (1) having a refrigerant inlet (1a) and a refrigerant outlet (1b) connected to a refrigerant pipe, The rotating blades (8) are rotatably mounted on the holding members (5) and (6), and a plurality of ice making tubes (2) penetrating along the length direction of the body (1) are arranged at intervals. A solution inlet (2a) and a solution outlet (2b) are provided at the protruding portion of each of the ice making tubes (2)... With respect to the holding members (5) and (6). A solution pipe (18) is connected to the solution outlet (2b) so that the ice making solution flows through the ice making tubes (2)... In series. It is necessary to control the liquid level of the liquid refrigerant individually, as in the multistage ice making device proposed earlier, while flowing the ice making solution in series. , Each ice making tube (2)
Thus, the temperature of the inner wall can be made almost uniform, and ice formation in each ice making tube (2) can be made uniform.

相俟ってコスト安にできるのである。Therefore, the control system for controlling the liquid level of the refrigerant can be simplified, the cost can be reduced accordingly, and the excessive force acting on the rotating blade (8) can be avoided. A plurality of ice making tubes are penetrated between the lids, one end and the other end thereof are exposed to the outside, and a solution pipe is connected to the exposed one end and the other end to form a plurality of ice making tubes. Since it is possible to assemble the ice making tubes and supply the ice making solution, there is no need to provide the branch pipe (M) and the inlet and outlet headers in the multi-stage ice making device, and the structure can be simplified. The cost can be reduced in combination with the simplification of the control system.
