[0021]

Embodiments of the present invention will be described below with reference to the drawings.

(Embodiment 1) FIG. 1 schematically shows a configuration diagram of a beverage cooling apparatus according to a first embodiment of the present invention. In FIG. 1, reference numeral 13 denotes a supercooling heat exchanger for exchanging heat of water 19a in a water tank 19 with a refrigerant in a heat pump circuit 1 to generate water in a supercooled state.
a is a circulation pump for sending a to the subcooling heat exchanger 13 through the water circuits 15 and 16. 17 is a supercooling heat exchanger 1
A temperature sensor 18 detects the temperature of the water flowing out of the water circuit 3 and flowing through the water circuit 16. The temperature sensor 18 is based on a signal received from the temperature sensor 17 so that the temperature of the water flowing through the water circuit 16 becomes a predetermined temperature T1. Water circuit 1 via circulation pump 14
It is a control unit for controlling the amount of water flowing through 5 and 16.
19b is a sherbet-like ice formed by a phase change of supercooled water. Subcooling heat exchanger 13
The heat exchangers other than the liquid-filled heat exchangers, such as a plate heat exchanger and a double tube heat exchanger, were used. Temperature sensor 17
Although a thermistor was used, a thermocouple or a resistance temperature detector may be used.

The operation and operation of the beverage cooling apparatus configured as described above will be described below. First, the water 19a stored in the water tank 19 is sent to the subcooling heat exchanger 13 by the circulation pump 14, and the heat pump circuit 1
After being cooled by heat exchange with the refrigerant, the water flows out to the water tank 19 via the water circuit 16. At this time, the predetermined temperature T1 is set to a temperature below the freezing point, and the control unit 18 controls the circulation pump 1 so that the temperature detected by the temperature sensor 17 becomes T1.
When the amount of water is controlled via 4, the water flowing out of the subcooling heat exchanger 13 becomes supercooled water that is a liquid phase even at a temperature below the freezing point. If water does not have an ice nucleus even if it is cooled to a temperature below the freezing point, it becomes supercooled water that cannot change its phase to ice. However, if ice nuclei are generated in the supercooled water or the flow is disrupted, the phase changes instantaneously to ice, and as the supercooled temperature increases, the phase changes to ice even with slight disturbance I do. Accordingly, the water in the supercooled state flowing through the water circuit 16 flows into the water tank 19 and changes phase into ice at the moment when the water flow fluctuates. At this time, the generated ice has a fluid sherbet-like shape. Becomes Accordingly, sherbet-like ice 19b is accumulated in the water tank 19 together with the water 19a, so that the cooling heat capacity of the water tank 19 can be dramatically increased.
The beverage to be sold is liquid sherbet-like ice 19
After quenching by the beverage cooling heat exchanger 5 immersed in b, it can be poured into the cup 12.

As described above, in this embodiment, the supercooling heat exchanger 13, the water circuits 15, 16 and the control unit 18 are installed, and the water 19a in the water tank 19 is cooled to a supercooled state. Is formed in the water tank 19, so that the cooling capacity of the water tank 19 is increased, so that the water tank 19 can be made much smaller and lighter than the conventional water tank 11. Further, since the sherbet-like ice 19b has fluidity, the water 19a is stirred while moving in the water tank 19, so that the heat transfer performance of the beverage cooling heat exchanger 5 immersed in the water tank 19 is improved, and Heat exchanger 5
Can be reduced in size. Therefore, not only can the size of the beverage cooling device be easily reduced, but also the available space can be increased by reducing the size of the water tank 19, and the types of drinks that can be sold can be increased.

The amount of the sherbet-like ice 19b accumulated in the water tank 19 of the present embodiment depends on the amount of the sherbet-like ice 1b.
9b so that the water tank 19 can efficiently flow through the water tank 19.
The volume ratio was set to be about 50% to 80%, but by further increasing the proportion of accumulated ice,
The water tank 19 can be made more compact.

Although the temperature sensor 17 of this embodiment is installed in the water circuit 16, when the characteristics of the cooling capacity of the heat pump circuit 1 can be grasped, the temperature sensor 17 is switched to the water circuit 1.
5, the same effect can be obtained by calculating the amount of water from the detected temperature and the cooling capacity characteristic and controlling the circulation pump 14 so that the calculated amount of water is obtained.

In this embodiment, the liquid stored in the water tank 19 is water. However, it is also possible to add brine or the like to the water to further lower the freezing point temperature and store the heat. in this case,
Since heat is stored at a lower temperature, the cooling heat capacity increases, and the water tank 19
Can be further reduced in size. The predetermined temperature T1 when brine is added to water is set to a value according to the amount of brine added.

The amount of water flowing through the water circuits 15 and 16 can be controlled by installing a flow control valve in the water circuit 15 in addition to controlling the circulation pump 14. Also,
The same effect can be obtained by providing an inverter circuit in the heat pump circuit 1 and controlling the output of the compressor so that the temperature of the water to be cooled becomes a predetermined temperature T1.

The amount of water circulating so that the temperature of the water cooled by the supercooling heat exchanger 13 becomes a predetermined temperature T1, or the temperature of the water in the ice heat storage tank 9 without controlling the heat pump circuit 1. Gradually decreases, and after a certain period of time, supercooled water is generated from the supercooling heat exchanger 13,
Sherbet-like ice is accumulated in the ice heat storage tank 9. Therefore, simplification of the apparatus and cost reduction can be achieved.
However, the temperature of the supercooled water generated in the supercooling heat exchanger 13 with the operation time further decreases, and the lower the temperature of the supercooled water, the more easily the phase changes to ice.
When cooled to a temperature close to −7 ° C., water changes phase into ice in the flow path of the heat exchanger and blocks the flow path. Therefore, the cost of the apparatus can be reduced, but the amount of ice that can be stored in the ice heat storage tank 9 decreases.

In this embodiment, the heat pump circuit 1 is constituted by a cycle in which a refrigerant is circulated by using a compressor. However, the refrigerant is absorbed by an absorbent by an absorber and generated by a regenerator. The same effect can be obtained even if the apparatus is constituted by an absorption cycle.

Further, in this embodiment, the water in the water tank 19 is circulated by using the circulation pump 14, but it is also possible to use a natural circulation type by utilizing the head difference of the water surface of the water tank 19, Cost reduction can be realized.

The supercooling heat exchanger 13 of this embodiment is
Although a counter flow is used, a similar effect can be obtained even if the cross flow or the cross flow is adopted.

(Embodiment 2) FIG. 2 schematically shows the configuration of a beverage cooling apparatus according to a second embodiment of the present invention.
In FIG. 2, reference numeral 16a denotes a water circuit provided so as to discharge supercooled water flowing out of the supercooling heat exchanger 13 from above the water tank toward the water surface of the water tank. In FIG. 2, an ice circuit 10 for supplying chip-shaped ice to a cup 12 is provided.
And the ice making unit 9 is omitted.

The operation and operation of the beverage cooling device configured as described above will be described below. Example 1
By the same operation as described above, the water flowing out of the supercooling heat exchanger 13 becomes supercooled water that is a liquid phase even at a temperature below the freezing point. Even if the water is cooled to below the freezing point and becomes supercooled water, if the ice nucleus or the flow of water is small,
Cannot change phase to ice. Therefore, the water tank 1 is moved from the water circuit 16.
If the supercooled water does not flow into the supercooled water 9 when the supercooled water flows into the water tank 19 as it is,
Not only cannot produce ice, but also reduces the efficiency of the device. Thus, as in the present embodiment, when the supercooled water flowing out of the water circuit 16a is discharged from above the water tank 19 toward the water surface of the water tank 19, the supercooled water rushes to the water surface of the water tank 19. Phase changes to ice due to the impact of well landing. At this time, the generated ice has a fluid sherbet shape. Therefore, it is possible to surely change the phase of the generated or cooled water into ice and accumulate the sherbet-like ice 19b together with the water 19a in the water tank 19, so that the cooling heat capacity of the water tank 19 is dramatically increased. Can be. In addition, the sherbet-like ice 19b is buoyant due to the difference in density between the water 19a and the water 19a, so that the ice 19b stays in the upper part of the water tank 19 and cannot accumulate ice in the lower part. Convection occurs in the water tank 19 due to the momentum of landing on the water surface of the water tank 19, so that sherbet-like ice can be accumulated in the lower part of the water tank 19.

As described above, in this embodiment, the water circuit 16a is installed, the water 19a in the water tank 19 is cooled to a supercooled state, and then the water in the supercooled state is discharged from above the water tank 19 toward the water surface. Since the supercooled water can be surely phase-changed into ice because of the configuration described above, ice can be efficiently accumulated in the water tank, and the cooling capacity of the water tank 19 increases. The water tank 11 can be significantly smaller and lighter than the example water tank 11. Further, since convection occurs in the water tank 19 due to the energy when the supercooled water lands on the water tank 19, ice can also accumulate in the lower part of the water tank 19, so that the cooling heat capacity that can be accumulated in the water tank 19 increases. Further, the size and weight of the water tank 19 can be reduced.

In this embodiment, as shown in FIG. 2, the height h at which the supercooled water is discharged from the water circuit 16a is 0.1H <h (the height of the water tank 19 is assumed to be H). ), The water in the supercooled state definitely changed to ice. The height h to be released depends on the installation space inside the aircraft,
As high as possible, ice can be efficiently accumulated and the amount of ice that can be accumulated can be increased.

In the present embodiment, the water circuit 16a is installed so that the supercooled water lands on the water surface of the water tank. However, the water circuit 16a is provided so as to hit the wall surface of the water tank 19 or the beverage cooling heat exchanger 5. Even if the circuit 16a is configured, it is possible to generate sherbet-like ice. In particular, when the heat is discharged so as to hit the beverage cooling heat exchanger 5, the heat transfer of the beverage cooling heat exchanger 5 is promoted, so that the size of the beverage cooling heat exchanger 5 can be reduced.

(Embodiment 3) FIG. 3 schematically shows a configuration diagram of a beverage cooling apparatus according to a third embodiment of the present invention.
In FIG. 3, reference numeral 19 c denotes a water tank partition plate that forms two sections A and B in the water tank 19. Since the water tank partition plate 19 c has holes, water 19 a in the water tank 19 flows between the sections A and B. Can be issued. Beverage cooling heat exchanger 5 is section A
, And water in a supercooled state generated by the supercooling heat exchanger is discharged to the section A.

The operation and operation of the beverage cooling device configured as described above will be described below. By the same operation as the first and second embodiments, the supercooling heat exchanger 1
The water flowing out of 3 becomes supercooled water which is a liquid phase even at a temperature below the freezing point, and is discharged to the section A of the water tank 19. The supercooled water changes its phase into ice due to the impact received when it lands on the water surface, so that sherbet-like ice can be accumulated in the section A. The water in the section A is pushed out to the section B through the hole of the water tank partition plate 19c by the sherbet-shaped ice, and then sent to the subcooling heat exchanger 13 by the circulation pump 14 to become the supercooled water and becomes the section. Released into A. When a predetermined amount of sherbet-like ice is accumulated in the section A, the sherbet-like ice moves to the section B through the hole of the water tank partition plate 19c because the sherbet-like ice has fluidity. Is accumulated, the cold heat capacity accumulated in the water tank 19 is the same regardless of whether the water tank partition plate 19c is installed. Therefore, a constant amount of sherbet-like ice can be constantly stored in the section A of the water tank 19, and convection occurs in the section A due to the momentum of the supercooled water landing on the surface of the section A. The heat transfer coefficient of the beverage cooling heat exchanger 5 can be made constant at a high value, as compared with a structure in which no compartment is formed in 19. In addition, water tank 19
Even if there is not enough ice stored in
The sherbet-like ice is accumulated in the beverage, so that the beverage can be cooled by the beverage cooling heat exchanger 5.

As described above, in this embodiment, the water tank partition plate 19c is provided, and the water tank 19 is formed with the sections A and B. Therefore, the section A of the water tank 19 is constantly formed in a constant amount of sherbet-like shape. Ice can be stored. Therefore,
Since the heat transfer coefficient of the beverage cooling heat exchanger 5 can be kept constant at a high value, the beverage can be cooled stably and the size of the beverage cooling heat exchanger 5 can be reduced. Even in a state where sufficient ice is not stored in the aquarium 19, sherbet-shaped ice is first accumulated in the section A, so that even when a large amount of cold beverages are sold in summer, the beverage can be cooled stably. It can be carried out.

In this embodiment, two sections A and B are formed in the water tank 19, but the same effect can be obtained by forming more sections.

(Embodiment 4) FIG. 4 schematically shows the configuration of a beverage cooling apparatus according to a fourth embodiment of the present invention.
In FIG. 4, reference numeral 13a denotes a supercooling heat exchanger that generates water in a supercooled state by exchanging water 19a in the water tank 19 with the refrigerant in the heat pump circuit 1 so as to be submerged in the water 19a in the water tank 19. The supercooled water generated in the supercooling heat exchanger 13a is installed and flows out to the water tank 19 as it is. As the supercooling heat exchanger 13a, a heat exchanger such as a plate heat exchanger or a double tube heat exchanger is used, and a heat exchanger having the same specifications as the supercooling heat exchanger 13 of the first embodiment is used. Can be.

The operation and operation of the beverage cooling device configured as described above will be described below. Example 1
By the same operation described in (1), water in a supercooled state is generated by the supercooling heat exchanger 13a, and is discharged as it is from the supercooling heat exchanger 13a into the water in the water tank 19. The supercooled water has a feature that it changes phase to ice when there is a drift such as stagnation of the flow, and in this embodiment, the supercooled heat exchanger 13a
Changed into ice when discharged from the water tank 19. Therefore, in the configuration of the present embodiment, the sherbet-like ice 19b can be accumulated in the water tank 19 as in the first embodiment. Further, the sherbet-like ice 19b tends to stay in the upper part of the water tank 19 because buoyancy is generated due to a difference in density between the ice 19b and the water 19a.
Since the water 19a and the sherbet-like ice 19b are stirred by the supercooled water flowing out from the a, it becomes possible to accumulate the sherbet-like ice in the lower part of the water tank 19.

As described above, in this embodiment, since the supercooling heat exchanger 13a is provided so as to be submerged in the water tank 19, the cooling capacity of the water tank 19 is increased, and the water tank 19 is replaced with the conventional one. Not only can the water tank 11 be significantly smaller and lighter than the water tank 11, but also the water circuit 16 through which the supercooled water flows, the space where the supercooling heat exchanger 13 is installed, and the supercooling heat exchanger 13 Since a heat insulating material for heat insulation is not required, the size and cost of the device can be reduced. Further, since the supercooling heat exchanger 13a is configured to be submerged, the water in contact with the surface of the heat exchanger can be cooled, so that the efficiency of the apparatus is improved. In addition, water tank 19
The drastic miniaturization makes it possible to use available space and increase the types of beverages that can be sold.

In this embodiment, the supercooled water generated in the supercooling heat exchanger 13a is used as it is in the water tank 1.
9, when the supercooled water does not change into ice, the supercooled water generated by the supercooled heat exchanger 13a is used as described in the second embodiment. By adding a water circuit 16a for discharging water from above the water tank 19 to the surface of the water tank 19, sherbet-like ice can be reliably generated.

(Embodiment 5) FIG. 5 schematically shows a configuration diagram of a beverage cooling apparatus according to a fifth embodiment of the present invention.
In FIG. 5, reference numeral 20 denotes a beverage cooling heat exchanger that cools the beverage supplied from the beverage circuit 4 by exchanging heat with the water 19 a of the water tank 19, and 21 passes the water 19 a of the water tank 19 through the beverage cooling circuit 22. It is a circulation pump for sending to the beverage cooling heat exchanger 20. The beverage cooling heat exchanger 20 uses a heat exchanger such as a plate heat exchanger or a double tube heat exchanger,
It was installed outside the water tank 19.

The operation and operation of the beverage cooling device configured as described above will be described below. Example 1
By the same operation described in (1), sherbet-like ice 19b can accumulate in water tank 19 so as to be mixed with water 19a. Beverages to sell, or concentrates that are raw materials,
The dilution water enters the beverage cooling heat exchanger 20 through the beverage circuit 4 and is cooled by exchanging heat with the water sent to the beverage cooling heat exchanger 20 through the beverage cooling circuit 22 by the circulation pump 21. The cooled beverage is poured into the cup through the beverage circuit 6. After cooling the beverage or the like with the beverage cooling heat exchanger 20, the water 19a and the sherbet-like ice 1
9b is returned to be stirred. The sherbet-like ice 19b is buoyant due to a difference in density between the water 19a and the water 19a, so that the ice 19b stays in the upper part of the water tank 19 and cannot accumulate ice in the lower part. Since the water 19a and the sherbet-like ice 19b are stirred by the water after cooling, the sherbet-like ice can be accumulated in the lower part of the water tank 19. Also,
Since the beverage 19 is forcibly cooled with the low-temperature water 19b through the beverage cooling heat exchanger 20, the heat transfer performance is improved as compared with the conventional beverage cooling heat exchanger 5, so that the size can be reduced. .

As described above, in this embodiment, the beverage cooling heat exchanger 20, the circulation pump 21, the beverage cooling circuit 22 and the like are installed, and the water after cooling the beverage and the like is combined with the water in the water tank 19 in a sherbet-like manner. Since the configuration in which the ice is stirred is increased, the amount of sherbet-shaped ice that can be accumulated in the water tank 19 increases, so that the water tank 19 can be reduced in size and weight. Further, since the beverage cooling heat exchanger 20 is installed outside the water tank 19, the volume of the water tank 19 occupied by the conventional beverage cooling heat exchanger 5 becomes unnecessary, and the water tank 19 is further reduced in size and weight. be able to. In addition, since the water for cooling the beverage is forced to circulate through the heat exchanger, the beverage cooling heat exchanger 20 can be more compact than the conventional beverage cooling heat exchanger 5.

In this embodiment, the beverage cooling heat exchanger 20
Was installed independently of the water circuits 15 and 16, but by installing the beverage cooling heat exchanger 23 in the water circuit 15 as shown in FIG. 6, the conventional beverage cooling heat exchanger 5 was occupied. The volume of the water tank 19 becomes unnecessary, and the water tank 19 is small,
The weight can be reduced.

(Embodiment 6) FIG. 7 is a schematic diagram showing a configuration of a beverage cooling apparatus according to a sixth embodiment of the present invention.
In FIG. 7, reference numeral 20 a denotes a beverage cooling heat exchanger that cools the beverage supplied from the beverage circuit 4 by exchanging heat with the water 19 a of the water tank 19, and is installed so as to be submerged in the water 19 a of the water tank 19. A heat exchanger such as a heat exchanger or a double tube heat exchanger was used. As the beverage cooling heat exchanger 20a, a heat exchanger having the same specification as the beverage cooling heat exchanger 20 of the fifth embodiment can be used.

The operation and operation of the beverage cooling device configured as described above will be described below. Example 1
By the same operation described in (1), sherbet-like ice 19b is accumulated in the water tank 19 so as to be mixed with the water 19a. The beverage to be sold or the concentrated liquid or dilution water as the raw material enters the beverage cooling heat exchanger 20a installed so as to be submerged in the water tank 19 through the beverage circuit 4, and drink cooling heat exchange through the beverage cooling circuit 22 by the circulation pump 21. Vessel 20
It exchanges heat with the water sent to a and is cooled. The cooled beverage is poured into the cup through the beverage circuit 6. The water after cooling the beverage or the like with the beverage cooling heat exchanger 20a is returned to the water tank 19 as it is so that the water 19a and the sherbet-like ice 19b are stirred. The sherbet-like ice 19b is
Since the buoyancy is generated due to a density difference between the water 19a and the water 19a, the ice is not allowed to accumulate in the upper part of the water tank 19 and the lower part cannot be accumulated. , Water 19a and sherbet-like ice 19
Since b was stirred, it became possible to accumulate sherbet-like ice in the lower part of the water tank 19. Further, since the beverage 19 is forcibly cooled through the beverage cooling heat exchanger 20a with the low temperature water 19b, the heat transfer performance is improved as compared with the conventional beverage cooling heat exchanger 5, so that the size is reduced. Can be.

As described above, in this embodiment, the water tank 1
9 is installed a beverage cooling heat exchanger 20a to be submerged in,
Since the water after cooling the beverage or the like is configured to stir the water in the water tank 19 and the sherbet-shaped ice, the amount of sherbet-shaped ice that can be accumulated in the water tank 19 increases.
9 can be reduced in size and weight. In addition, since the water for cooling the beverage is forced to circulate through the heat exchanger, the beverage cooling heat exchanger 20 can be more compact than the conventional beverage cooling heat exchanger 5. Also,
Since a heat insulating material for insulating the beverage cooling heat exchanger 20a is not required, the cost of the apparatus can be reduced.

In this embodiment, the beverage is cooled by forcibly sending water to the beverage cooling heat exchanger 20 a by the circulation pump 21, but the beverage cooling heat exchanger 20 a is submerged in the water tank 19. Since the beverage is cooled by water having a low temperature in contact with the heat exchanger surface or ice in the form of sherbet, the beverage to be sold does not require relatively cooling or the beverage supplied from the beverage circuit 4 When the temperature is low, the beverage or the like can be cooled without operating the circulation pump 21 to circulate the water. Therefore, the running cost of the apparatus can be kept low.

(Embodiment 7) FIG. 8 schematically shows a configuration diagram of a beverage cooling apparatus according to a seventh embodiment of the present invention.
In FIG. 7, reference numeral 24 denotes a beverage cooling heat exchanger that exchanges heat between the beverage supplied from the beverage circuit 4 and water flowing through the supercooling heat exchanger 13 to cool the beverage. Beverage cooling heat exchanger 2
No. 4 used a heat exchanger such as a plate heat exchanger or a double tube heat exchanger, and was installed outside the water tank 19.

The operation and operation of the beverage cooling apparatus configured as described above will be described below. When the beverage is not sold, the supercooled water is generated by the subcooling heat exchanger 13 and passes through the beverage cooling heat exchanger 24 by the same operation described in the first embodiment, and then the water tank 1
Release to 9. The supercooled water is discharged into the water tank 19 and changes its phase into ice due to the impact received upon landing on the surface of the water 19a. In the water tank 19, sherbet-like ice 19b is accumulated together with the water 19a. Therefore, the water tank 19
Can be dramatically increased. When selling the beverage, the water in the water tank 19 is circulated by the circulation pump 14 so as to circulate through the beverage cooling heat exchanger 24, and the beverage and the like sent from the beverage circuit 4 are cooled. It is poured into the cup 12 through the circuit 6. Further, even when the supercooled water is generated and discharged to the water tank 19 through the beverage heat exchanger 24, the beverage can be sold, and the beverage and the like sent from the beverage circuit 4 can be supplied to the beverage cooling heat exchanger. After being cooled by exchanging heat with the supercooled water at 24, it is poured into the cup 12 through the beverage circuit 6. Therefore, even if the ice is not accumulated in the water tank 19, the beverage can be cooled whenever supercooled water is generated.

As described above, in the present embodiment, the beverage cooling heat exchanger 24 is provided, and the beverage and the like are cooled by the water in the water tank 19 or the supercooled water. The beverage can be cooled even if the beverage is sold in a large amount and the cooling capacity of the heat stored in the water tank 19 cannot cover the beverage.

(Embodiment 8) FIG. 9 schematically shows a configuration diagram of a beverage cooling apparatus according to an eighth embodiment of the present invention.
In FIG. 9, reference numeral 24 a denotes a beverage cooling heat exchanger that exchanges heat with the water flowing through the supercooling heat exchanger 13 to cool the beverage supplied from the beverage circuit 4, and the water 19 a in the water tank 19.
It is installed so that it is submerged in the inside, and the beverage cooling heat exchanger 24a
Is flowed out to the water tank 19 as it is. The beverage cooling heat exchanger 24a uses a heat exchanger such as a plate heat exchanger or a double tube heat exchanger.
The heat exchanger having the same specifications as the beverage cooling heat exchanger 24 can be used.

The operation and operation of the beverage cooling device configured as described above will be described below. When the beverage is not sold, the same operation described in the first embodiment causes the supercooled water to be generated by the supercooling heat exchanger 13 and passed through the beverage cooling heat exchanger 24a before being placed in the water tank 19. Released to The water in the supercooled state has a characteristic of changing to ice when there is a drift such as stagnation of the flow. In this embodiment, the water changes to ice when discharged from the beverage cooling heat exchanger 24a to the water tank 19. . Therefore, in the configuration of the present embodiment, the sherbet-like ice 19b can be accumulated in the water tank 19 as in the first embodiment. In addition, the sherbet-like ice 19b tends to stay in the upper layer of the water tank 19 because buoyancy is generated due to a difference in density between the water 19a and the water 19a. Water 19a and sherbet-like ice 1
Since the 9b is stirred, it becomes possible to accumulate sherbet-like ice in the lower part of the water tank 19. When selling a beverage, the circulation pump 14 causes the water in the water tank 19 to flow through the beverage cooling heat exchanger 24a, and the beverage circuit 4
Is cooled, and the cooled beverage or the like is poured into the cup 12 through the beverage circuit 6. In addition, water in a supercooled state is generated, and the water tank 1 is passed through the beverage heat exchanger 24.
Even when releasing to 9, the beverage can be sold,
The beverage or the like sent from the beverage circuit 4 is cooled by exchanging heat with the supercooled water in the beverage cooling heat exchanger 24 and then poured into the cup 12 through the beverage circuit 6. Therefore, even if the ice is not accumulated in the water tank 19,
Cooling of the beverage can take place whenever supercooled water is being produced.

As described above, in the present embodiment, the beverage cooling heat exchanger 24a is installed so as to be submerged in the water tank 19,
In the case where the beverage or the like is cooled by the water in the water tank 19 or the supercooled water, the sales amount of the cold beverage is large in summer or the like, and the cooling of the beverage cannot be covered by the cold heat capacity stored in the water tank 19. The beverage can be cooled even if the above occurs. Further, the water circuit 16 through which the water in the supercooled state flows is simplified, and the space in which the beverage cooling heat exchanger 13 is installed and the heat insulating material that insulates the beverage cooling heat exchanger 24a become unnecessary. A reduction in size and cost can be realized.

In this embodiment, the beverage is cooled by forcibly sending water to the beverage cooling heat exchanger 24a by the circulation pump 14, but the beverage cooling heat exchanger 24a is submerged in the water tank 19. Since the beverage is cooled by low-temperature water or sherbet-shaped ice in contact with the heat exchanger surface, the beverage to be sold does not require relatively cooling, or the beverage supplied from the beverage circuit 4 When the temperature is low, the beverage can be cooled without operating the circulation pump 14 to circulate water. Therefore, the running cost of the apparatus can be kept low.

b is a control unit having an open / close control function.

The operation and operation of the beverage cooling device configured as described above will be described below. Example 1
By the same operation described in (1), supercooled water is generated by the subcooling heat exchanger 13 and the water tank 19 has water 19a.
And ice 19b in the form of sherbet can accumulate so as to be mixed. The beverage to be sold or the concentrated liquid or dilution water as the raw material enters the beverage cooling heat exchanger 5 through the beverage circuit 4, is cooled, and then poured into the cup 12 through the beverage circuit 6. The cooling heat capacity that can be stored in the water tank 19 is the water tank 1
Since it is proportional to the amount of water stored in the water tank 9, by changing the water level of the water tank 19, it is possible to control the cold heat capacity that can store heat in the water tank. That is, in the configuration of the present embodiment, when the water level in the water tank 19 is detected by the water level sensor 28 and the water level is raised, the opening / closing valve 26 a is controlled via the control unit 29, When the pressure is lowered, the opening / closing valve 26b is controlled via the control unit 29, the water level is adjusted by an operation of draining to the outside through the drain circuit 27, and the cooling heat capacity capable of storing heat can be controlled.

Therefore, it is possible to operate the apparatus optimally for the sales situation, so that the running cost can be kept low.

Further, in this embodiment, the water supply to the water tank 19 is not directly injected into the water tank 19 but flows through the supercooling heat exchanger 13 and is injected into the water tank 19 after being cooled to the supercooled state. The configuration was adopted. Therefore, it is possible to prevent the accumulated sherbet-like ice from melting due to the water supply. However, if simplification of the water supply circuit 25 is prioritized even if the efficiency of the device is reduced, the water may be directly injected into the water tank 19.

(Embodiment 10) FIG. 11 shows a tenth embodiment of the present invention.
FIG. 3 schematically illustrates a configuration diagram of a beverage cooling device according to an embodiment of the present invention. In FIG. 11, reference numeral 30 denotes a laminated heat exchanger;
This is a replacement of the supercooling heat exchanger 13 of the first embodiment. FIG. 12 is an exploded perspective view of the laminated heat exchanger 30.
The laminated heat exchanger 30 includes a refrigerant plate 32, a water plate 3
4, formed by sequentially stacking partition plates 33 inserted between these plates 32 and 34; Refrigerant plate 3
2 has a coolant passage slit 32a and a water passage slit 32b, which are slit-shaped holes. Water plate 3
4 is a refrigerant passage slit 34a which is a slit-shaped hole,
A water passage slit 34b is formed. The partition plate 33 includes a coolant passage slit 33a, which is a slit-shaped hole.
And a water passage slit 33b. The coolant passage slit 32a is formed by the top plate 31 and the partition plate 3
3 or between the partition plates 33 on both sides to form a coolant channel. Water channel slit 34a
Forms a water channel by being sandwiched between the partition plates 33 on both sides. Water passage slit 3 of refrigerant plate 32
2b, and the coolant passage slit 33 of the partition plate 33
a, the water passage slit 33b, and the coolant passage slit 34a of the water plate 34 form a space penetrated by being stacked in order, and the inflow passages 36a, 37a for sending the coolant and water to the flow path of each plate, and Refrigerant or water that has exchanged heat in each flow path is combined to form a stacked heat exchanger 3
Outflow passages 36b and 37b for allowing the air to flow out from zero. The top plate 31 is arranged on the uppermost surface of the stacked plates, and the end plate 35 is arranged on the lowermost surface, and each slit is used as a closed space.

The height of the refrigerant flow path of the laminated heat exchanger 30 and the flow path height of the water flow path are the thicknesses of the refrigerant plate 32 and the water plate 34, and the width of the flow path is the refrigerant flow path. The width of the slit 32a is equal to the width of the water passage slit 34a. In this embodiment, the thickness of the water plate 34 is set to 0.1 to
The thickness of the plate 34, the width of the slit 34a, and the number of plates to be laminated were designed so that the flow rate of the water in the water flow path was laminar (the Reynolds number was 1000 or less). The flow of water flowing through the water channel becomes laminar,
Generally, heat transfer in a laminar flow is considered to be low. However, when the flow path height is in the range of 0.1 to 2.0 mm as in the present invention, the temperature boundary layer is thinned and heat transfer is promoted. You.

The operation and operation of the beverage cooling device configured as described above will be described below. The supercooled water generated in the supercooling heat exchangers 13 and 13a has a characteristic that the phase changes from a liquid phase to ice when subjected to even a slight impact. Even a turbulent flow will change to ice. Subcooling heat exchanger 1
When the plate 13 or 13a is constituted by a plate heat exchanger or a double tube heat exchanger in which the heat transfer of water is turbulent, when the supercooled water is cooled to a certain temperature below the freezing point. In some cases, the phase changes to ice due to the influence of the turbulence of the flow and the like, and the flow path is blocked, so that it is necessary to stop the operation of the apparatus. Frequent shutdown of the device reduces the durability of the compressor in the heat pump circuit. Therefore, when the supercooling heat exchangers 13 and 13a are configured by the stacked heat exchangers 30 as in the present embodiment, the flow of water in the water flow path is laminar and does not involve turbulence. The supercooled water can pass through the flow path without phase change to ice. The water in the supercooled state undergoes a phase change from a liquid phase to a fluid sherbet-like ice due to the impact received when it is discharged into the water tank 19 as in the first embodiment.

As described above, in this embodiment, since the heat exchanger for cooling water to the supercooled state is the laminated heat exchanger 30, the generated supercooled water is used as the heat exchanger. The water can be discharged to the water tank 19 without phase change to ice in the water flow path, so that supercooled water can be continuously generated without stopping the operation of the apparatus.
Therefore, the efficiency and durability of the device are improved.

Further, since the height of the flow path of the stacked heat exchanger 30 is smaller than that of the plate heat exchanger or the double tube heat exchanger, the internal volume is reduced even if the heat transfer area is the same. Therefore, according to the configuration of the present embodiment, the amount of the refrigerant to be charged into the device can be reduced, and the size of the device can be reduced.

In this embodiment, the laminated heat exchanger 30 is used as the supercooling heat exchangers 13 and 13a, but the beverage cooling heat exchangers 20, 20a, 23, 24 and 24 are used.
a can be used for the beverage cooling heat exchanger 20,
20a, 23, 24, and 24a can be reduced in size.
