An inner tube (A) for producing ice cubes is installed in the center of an outer tube (B) having a larger diameter than the inner tube (A), and the inner tube (A)
) and a rotating drum (D) with blades (C) on the outer periphery.
An ice-making evaporator is configured in such a way that a refrigerant for cooling the solution flows between the inner tube (A) and the outer tube (B), and the inner tube is heated by the evaporation of the refrigerant. The solution flowing through (A) is supercooled and freezes on the inner wall of the inner tube (B), and the rotation of the drum (D) causes ice to form on the inner wall of the inner tube due to the scraping action of the blades (C). There is a device that scrapes off the ice that forms and produces ice in the form of a slurry.

管(B)とから成る1台の製氷用蒸発器を用い、複数台
のファンコイルユニット(F。(Problem to be Solved by the Invention) In the conventional example described above, one ice-making evaporator consisting of a pair of inner tubes (A) and outer tubes (B) is used, and a plurality of fan coils are used. Unit (F.

が不足する問題が生ずる。) to (F4) generate the slurry ice used in the fan coil units (F1) to (F4).
In a building air conditioner where a large number of units are installed in 4), the amount of ice used increases, and a problem arises in that the amount of ice produced is insufficient with only one ice-making evaporator.
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。Therefore, when increasing the amount of ice made in accordance with the amount used, 1
Since there is a limit to the size of one ice-making evaporator, it is necessary to use a plurality of ice-making evaporators.

蒸発器を用いる必要が生ずるのである。That is, in order to increase the amount of ice made in the ice-making evaporator having the above-described configuration, it is conceivable to increase the diameter or length of the inner tube (A) and outer tube (B).
Considering the decrease in ice-making performance and the increase in the load on the motor that drives the drum (D), there is a natural limit, and it is impossible to cope with an increase in usage, so it is necessary to use multiple ice-making evaporators. A need arises.

-35Ei No. 31) This multi-stage ice making device has an inner tube (A
) placed in the center of the outer tube (B) (J)
are arranged horizontally in pairs, and these pairs of ice-making evaporators (J) (J) are stacked vertically in multiple stages,
A branch pipe (M) is branched from the refrigerant liquid pipe (K) into the outer pipe (B) of each of these evaporators (J) and has an expansion valve (L) interposed in the middle. and each evaporator (J)
The liquid refrigerant is supplied between the outer tube (B) and the inner tube (A) of the evaporators (J), and the lowermost evaporator is supplied to each inner tube (A) of the evaporator (J). Solution pipes (N) are connected so that the ice-making solution flows in series from the containers (J) (J) to the evaporators (J) (J) in the uppermost layer. In addition, in FIG. 5, (S) is the refrigerant inlet header,
(R) is the exit header.

タ負荷を増大させたりする問題が生ずるのである。On the other hand, when the evaporators (J) are stacked in multiple stages to allow the solution to flow in series, a temperature difference occurs in the solution between the upstream and downstream sides of the solution flow, and as a result, each of the The refrigerant flow flowing into the evaporator (J) is uneven, causing uneven ice formation in each of the evaporators (J), causing strain on the rotating blades installed in the inner pipe (A). This causes a problem in that a large amount of force acts on the motor, increasing the motor load.

。(Effects of the Invention) As described above, the present invention has the refrigerant inlet (1) connected to the refrigerant pipe.
Holding members (5) and (6) are provided on both longitudinal sides of a body (1) having a refrigerant outlet (1b) and a rotary blade (8). A plurality of ice-making tubes (2), which are rotatably installed inside the body (1) and pass through the body (1) along the length direction, are held at intervals,
The holding member (5) (E3) of each ice making tube (2)...
), a solution inlet (2a) and a solution outlet (
2b), and these solution inlet (2a) and solution outlet (
2b), the solution piping (18) is connected so that the ice-making solution flows through each of the ice-making tubes (2) in series, so that ice-making is possible for a plurality of ice-making tubes (2). Since the ice making solution is not passed in series, the inner wall temperature of each ice making tube (2) can be controlled without the need to individually control the liquid level height of the liquid refrigerant as in the multi-stage ice making device proposed earlier. This makes it possible to uniformly generate ice in each ice making tube (2).

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, and the cost can be reduced accordingly.
It is also possible to avoid applying unreasonable force to the body (1), and the refrigerant inlet (1a) and refrigerant outlet (1b)
), there is no need to provide a branch pipe (M) or an inlet and outlet header in the multi-stage ice making device,
This structure is simple, and together with the simplification of the control system, the cost can be reduced.
