Description

COOLING WATER RECOVERY DEVICE OF WATER-COOLING DEICE TECHNOLOGY {APPARATUS FOR RETRIEVE COOLING WATER OF WATER-COOLED ICE MACHINE}

The present invention relates to, for example, a water-cooled ice maker using water as a heat exchange cooling medium. More specifically, by recovering and recycling all the cooling water consumed in the condenser of the ice maker, the operation cost of the ice maker is greatly reduced and the cooling water is low. The present invention relates to a cooling water recovery device of a water-cooled ice maker that maximizes the yield by increasing the condensation effect with temperature, while maintaining the convenience of operation and maintenance.

In general, an ice maker performs an ice making operation in which ice making is performed by freezing water in an ice making member equipped with an ice room, and an ice making process that removes the ice made by raising the temperature by hot gas or the like from the ice making member and sends it to the ice storage compartment. The section is repeatedly operated as the first ice making operation, and the ice making operation is continued. In this case, the ice making capacity depends largely on the environmental conditions under which the ice maker operates. Notable is the external temperature outside the ice maker. For example, if the ambient temperature is above 30 ° C during the summer when the ice demand is high, the heat dissipation in the condenser is not smooth and the temperature of the evaporator does not fall to the reference temperature (about -15 ° C) to produce ice. Occurs. If it does not fall to the reference temperature, ice is not properly generated in the ice making member.

As such, if the heat dissipation of the condenser is not smooth, the evaporator's ability to produce ice is degraded, and consequently, the compressor, the condenser and the evaporator must be excessively operated in order to generate ice, and ice is generated from the evaporator. As the time required for the elongation to be lost, as well as the loss of energy, as well as the ice from the evaporator may not be produced in the desired thickness, the most important task is to improve the capacity of the evaporator by cooling the ice maker's condenser to the appropriate temperature. can do.

Accordingly, a water-cooled ice maker that supplies cooling water to the condenser and cools it as a method for preventing a decrease in power consumption efficiency and de-icing ability due to a lower heat radiation of the condenser.

1 is a cross-sectional view schematically showing the overall structure of a conventional water-cooled ice maker, and FIG. 2 is a block diagram illustrating an ice making process, an anisotropic process, and a cooling process of a condenser in the water-cooled ice maker of FIG. 1.

As shown in FIG. 1, the water-cooled ice maker includes a water supply unit 40 storing water supplied through a main water supply pipe 10 and a shunt pipe 14 coupled thereto, and a water supply pipe 10 and a shunt pipe 14. And a water supply valve 12 for supplying or blocking water to the water supply unit 40, an ice making unit 30 for supplying water from the water supply unit 40 to make ice, and fluid exchange with the ice making unit. To perform ice-making and ice-making and to heat-exchange with the water supplied through the main water supply pipe 10 and the cooling water supply pipe 26 coupled thereto to cool the refrigeration unit, and then exchange the cooling water with the cooling water drain pipe 28 and the drainage coupled thereto. It is installed between the ice making machine room 20 discharged through the hose 29 and the main water supply pipe 10 and the cooling water supply pipe 26 to supply the coolant to the ice making machine room 20 under the control of a control panel (not shown). And a coolant valve 25 for blocking and deicing It consists of the ice storage chamber 50 for storing the ice 60 created in (30).

In the above, the water supply unit 40, as shown in Fig. 1 and 2, the water tank 42 for receiving and storing the water supplied from the shunt tube 14 and the water stored in the water tank 42 injection station A pump 44 is provided to supply the high pressure to the 34 and to inject it through the injection nozzle 34a.

In the above, the ice making unit 30 has an ice making member 36 which is arranged on the upper part of the spray station 34 with a plurality of ice rooms 38 having a predetermined shape arranged at the lower part, and is provided on the upper part of the ice making member. It consists of an evaporator 32 for cooling and heating the ice making member 36 by heat exchange with air.

In addition, as shown in FIG. 2, the ice making machine chamber 20 is fluidly connected to an evaporator 32 for making ice by supplying a refrigerant, thereby compressing the low-temperature and low-pressure refrigerant gas evaporated into a high-temperature and high-pressure refrigerant gas. Between the compressor 21 to supply, the condenser 22 which exchanges the high temperature and high pressure refrigerant gas supplied from the compressor 21 with a cooling water, and converts it into a high pressure liquid refrigerant, and between the evaporator 32 and the condenser 22. An expansion pipe 23 installed to expand and supply the high-pressure liquid refrigerant in a low-temperature and low-pressure ideal flow state to the evaporator 32, and a hot gas valve 24 to be opened and closed according to the temperature of the ice making member 36; It is installed in the condenser 22 and circulates the cooling water supplied from the cooling water supply pipe 26 to cool the condenser 22 and consists of a continuous heat dissipation pipe 27 discharged through the cooling water drain pipe 28.

The ice-making process and the ice-making process of the conventional water-cooled ice maker made as described above are as follows.

First, before performing the ice making operation, the water supply valve 12 is opened to supply water through the main water supply pipe 10 and the shunt pipe 14 to fill the water tank 42 of the water supply part 40 with an appropriate level. . As described above, when the ice maker starts while the water tank 42 of the water supply part 40 is filled with the appropriate water level, the compressor 21 installed in the ice making machine chamber 20 is a low temperature or low pressure evaporated from the evaporator 32. The refrigerant gas of the condenser 22 is compressed and supplied at a high temperature and a high pressure so that condensation works well. The refrigerant gas compressed at high temperature and high pressure in the compressor 21 becomes a high pressure liquid refrigerant while being radiated in the condenser 22, and then passes through the expansion pipe 23 to a low temperature and low pressure ideal flow state in which the pressure drops sharply. It is supplied to the evaporator 32 of the ice making unit 30. In the evaporator 32, a refrigerant made of a low pressure liquid absorbs heat and is converted into a gas of low pressure to lower the ambient temperature of the ice making member 36 attached and fixed to the evaporator 32 of the ice making unit 30. When the ambient temperature of the ice making member 36 is lowered by the heat exchange of the evaporator 32 according to the circulation of the refrigerant, the pump 44 of the water supply unit 40 operates to bring the water in the water tank 42 to a constant pressure. It is supplied to the spraying station 34, and the water sprayed by the spraying nozzle 34a of the spraying station 34 becomes part of the ice in the ice making member 36 provided with the ice chamber 38, and the rest is intact. The water tank 42 is recovered again. The refrigerant having undergone heat exchange in the evaporator 32 is returned to the compressor 21 in the ice making machine chamber 20.

When the ice making process is continued and the ice is frozen to a desired thickness by heat exchange of the evaporator 32, the ice is separated from the ice room 38 of the ice making member 36.

In the ice-making process, when ice grows to an appropriate size, the hot gas valve 24 is opened by a temperature sensor (not shown) attached to the ice making member 36, and thus discharged from the compressor 21. High-temperature, high-pressure refrigerant gas is supplied to the evaporator 32, and the ice 60 grown in the ice chamber 38 of the ice making member 36 by the high-temperature, high-pressure refrigerant gas supplied to the evaporator 32 is After the separation is separated and stacked along the guide plate into the ice compartment 50. When the ice is separated from the ice making member 36, the ice is detected and the hot gas valve 24 is closed and the ice making operation is performed again.

In this series of processes, a large amount of work must be performed by the compressor 21 in order to make the water injected into the ice making member 36 of the ice making unit 30 into ice, and a large amount of heat is generated in the condenser 22. It must be dissipated.

Then, when the condenser 22 performs a sufficient amount of work to sufficiently lower the temperature of the evaporator 32, the temperature sensor not shown in the drawing senses the falling temperature of the evaporator 32, and the thickness of the ice is approximately 20 mm. When the detection temperature is about -18 ° C, the hot gas valve 24 is opened and hot gas is introduced to separate the ice from the ice chamber 38 of the ice making member 36. That is, in order to operate the hot gas valve 24 to separate the ice from the ice chamber 38 of the ice making member 36, the temperature of the evaporator 32 must be sufficiently increased.

In the ice making process for making ice as described above, until the water load sprayed on the ice making member 36 of the ice making unit 30 grows into ice and reaches a desired thickness of ice, The condenser 22 must dissipate a large amount of heat to change the gaseous compressed refrigerant into a liquid state.

However, especially when the temperature is above 30 ° C. or when the ice maker is continuously operated to generate a large amount of ice, such as in summer when the demand for ice is high, heat dissipation in the condenser 22 is not smooth due to overload, As a result, the temperature of the evaporator 32 may not fall to the reference temperature (-15 ° C) for producing ice. If it does not fall to the reference temperature, the ice is not properly generated in the ice room 38 of the ice making member 36, and the time until the ice grows is longer, so that the power consumption increases and the thickness of the desired ice. The disadvantage is that it does not grow.

To this end, when the ice making process is performed, a second temperature sensor (not shown) installed in the condenser 22 senses the temperature of the condenser 22 to open the coolant valve 25 that was initially closed when the set temperature is higher than the set temperature. do. When the coolant valve 25 is opened, water in the water supply pipe 10 enters the condenser 22 through the coolant supply pipe 26. Water entering the condenser 22 circulates along the heat dissipation pipe 27, takes heat from the condenser 22, then exits through the cooling water drain pipe 28, and is discharged through the drain hose 29. When the temperature of the condenser 22 falls below the set temperature, the cooling water valve 25 is closed again. Thus, the desired amount of ice is generated while repeating the supply and blocking of the cooling water.

However, in order to facilitate the heat dissipation of the condenser during the ice making process, the above-mentioned water-cooled ice maker cools the condenser by circulating the water supplied from the main water supply pipe along the heat dissipation pipe in the condenser through the cooling water supply pipe. Whenever, the water supplied from the main water supply pipe is heat-exchanged with the condenser and cooled, and the heat-exchanged water is discharged through the cooling water drainage pipe. As a result, water consumption is increased during ice making, and the operating cost of the ice maker is greatly increased.

In addition, by cooling the condenser with water directly supplied from the hot summer water supply pipe, the cooling time is long, which is pointed out as a problem that the condensation effect and the evaporation effect is lowered, the ice yield is lowered and the power consumption is large.

Therefore, it is desirable to provide a lower cost water-cooled ice maker in terms of cost while relieving the above-mentioned problems, and a water-cooled ice maker that is easier to increase and maintain ice production in terms of reliability.

Accordingly, an object of the present invention is to provide a cooling water recovery device of a water-cooled ice maker that recycles water that is exchanged heat exchanged in a condenser to cooling water, thereby minimizing operating costs. Is recovered in the cooling water tank, and the recovered water is circulated to the condenser by the cooling water circulation pump and cooled.

Another object of the present invention is to provide a cooling water recovery device of a water-cooled ice maker that increases the yield of ice by lowering the cooling water heat-exchanged in the condenser of the ice maker to an appropriate temperature to increase the condensation effect and the evaporation effect. It is achieved by cooling the water recovered in the external cooling water tank after the heat exchange in the condenser of the cooling in the external heat exchanger to circulate to the condenser of the ice maker.

It is another object of the present invention to cool a condenser of an ice maker, wherein the water supplied from a water supply pipe or a water recovered in an external cooling water tank is selectively circulated to the condenser of the ice maker to cool the water recovery apparatus of the water-cooled ice maker. This cooling water recovery apparatus is achieved by providing three sides at the inlet side and the outlet side of the condenser, respectively.

Another object of the present invention is to provide a cooling water recovery device of a water-cooled ice maker with ice generation and high power consumption efficiency within accurate ice control time.

Still another object of the present invention is to provide a cooling water recovery apparatus of a water-cooled ice maker that enables ice production by separately operating only an ice maker when an external heat exchanger breaks down.

It is composed of a blowing fan (135).

The ice making process and the ice making process of the cooling water recovery apparatus of the water-cooled ice maker according to the present invention as described above will be described in more detail with reference to FIGS. 3 and 4.

First, the ice making process for making ice in the ice maker according to the present invention is as described above. In summary, the refrigerant gas compressed in the first compressor 21 of the ice making machine 20 is liquefied while being radiated in the condenser 22. The liquefied refrigerant is supplied to the evaporator 32 of the ice making unit 30 through the first expansion pipe 23 to cause the ice chamber 38 of the ice making member 36 to generate ice.

When the water is supplied, the water supplied through the main water supply pipe 10, the water supply valve 12, and the shunt tube 14 is stored in a predetermined amount in the water tank 42 of the water supply unit 40, and the pump 44 And by spraying the ice making member 36 by the spray nozzle 34a of the spraying station 34, ice is frozen in the ice chamber 38 of the ice making member 36. When the ice making process is continued and the ice is frozen to a desired thickness by heat exchange of the evaporator 32, the ice is separated from the ice room 38 of the ice making member 36 by performing the ice making process as described above. The separated ice 60 is dropped and stored in the ice storage chamber 50.

On the other hand, in the ice making process for making ice as described above, the high temperature discharged from the compressor 21 until the water load sprayed on the ice making member 36 of the ice making unit 30 grows into ice and has a desired thickness of ice. In the refrigerant of the condenser 22 heats a large amount of heat to change the gaseous compressed refrigerant to a liquid state, at which the ambient temperature is 30 ℃ or more, such as summer, or to generate a large amount of ice If the ice maker is continuously operated, the heat dissipation in the condenser 22 is not smooth due to the overload, whereby the temperature of the evaporator 32 does not fall to the reference temperature (-15 ° C.) for producing ice. Occurs. To this end, at the initial stage of the ice making process, a control panel (not shown in the drawing) controls the first three-way side 100 for a predetermined time to store the water flowing from the main water supply pipe 10 in the cooling water tank 122. Open to (10), the second three-sided 110 is opened to the cooling water supply unit 120. When the first and second three-way sides 100 and 110 are opened, the water in the main water supply pipe 10 circulates along the cooling water supply pipe 26 and the heat dissipation pipe 27 in the condenser 22, and the cooling water drain pipe 28 ) Is stored in the cooling water tank 122 of the cooling water supply unit 120 at an appropriate level. When the coolant is stored in the coolant tank 122 at an appropriate water level, the water flowing into the main water supply pipe 10 is blocked, and the first and second three-sided sides 100 and 110 are opened toward the coolant supply unit 120.

Then, when the ice making process is performed in earnest so that the temperature of the first condenser 22 rises, the above-described second temperature sensor senses the signal and provides the signal to the control panel (not shown). The coolant circulation pump 124 of 120 is driven. When the cooling water circulation pump 124 is driven, the cooling water of the cooling water tank 122 enters the condenser 22 through the first three-way 100 and the cooling water supply pipe 26. Water entering the condenser 22 circulates along the heat dissipation pipe 27, deprives heat of the condenser 22, and then exits through the cooling water drain pipe 28 to the coolant tank 122 installed outside the ice maker. The coolant discharged by heat exchange in the first condenser 22 is approximately 45 ° C. to 55 ° C., depending on the ambient temperature of the first condenser 22, and the coolant passes through the coolant drain pipe 28. While stored in the coolant tank 122 is stored temperature drops from approximately 50 ℃ to 40 ℃.

As such, when the temperature of the water recovered and stored in the coolant tank 122 is high, the coolant temperature sensor 126 detects and sends a start signal to the second compressor 131 of the unit cooler 130 installed outside the ice maker. It becomes. The first compressor 131 compresses the refrigerant gas from low pressure to high pressure by the start signal provided from the coolant temperature sensor 126, and thus, the first heat exchanger 132 such as a condenser that is cooled by the blowing of the blower fan 135. Supplies). In the first heat exchanger 132, the high pressure is a liquid refrigerant while the gas refrigerant radiates heat, and is supplied to the second heat exchanger 134 such as an evaporator while the pressure is rapidly dropped through the second expansion pipe 133. In the second heat exchanger 134, a refrigerant made of a low pressure liquid becomes a gas of low pressure while absorbing heat from the cooling water tank 122. At this time, the cooling water of the cooling water tank 122 wrapped in the second heat exchanger 134 is dropped to a temperature of about 15 ℃ to 18 ℃ while heat exchange. When the coolant temperature of the coolant tank 122 is lowered to the above temperature by the second heat exchanger 134 while the coolant circulates, the lowered coolant is cooled by the coolant circulation pump 124. The temperature rises to approximately 19 ° C. from the cooling water supply pipe 26 and enters the condenser 22. Cooling water that enters the first condenser 22 circulates along the heat dissipation pipe 27, and deprives the heat of the condenser 22 sufficiently and then cools the water tank 122 through the water-cooled drain pipe 28 and the second three-way valve 110. ) Is recovered again. When the temperature of the condenser 22 falls below the set temperature, the first and second three-way sides 100 and 110 are closed, and the unit cooler 130 and the coolant circulation pump 124 are stopped. As described above, the cooling water discharged from the condenser 22 is recovered in the cooling water tank 122 in its entirety, and the condenser 22 is cooled while repeating the supply and blocking of the recovered cooling water to generate the desired amount of ice.

On the other hand, when the coolant stored in the coolant tank 122 is contaminated, the first three-sided 100 toward the coolant supply unit 120 and the second three-sided 110 by the operation of the control panel, the drain hose 29 ), And the cooling water circulation pump 124 is driven so that the contaminated cooling water in the cooling water tank 122 is discharged through the heat dissipation pipe 27, the cooling water drain pipe 28, and the drain hose 29 of the condenser 22. . When the discharge is completed, the first three-way side 100 is opened toward the main water supply pipe 10, and the second three-way side 110 is opened toward the cooling water supply unit 120, and clean coolant is stored in the cooling water storage tank 122.

When a failure occurs in the unit cooler 130 and the coolant supply unit 120 installed outside the ice maker, the first and second triangular sides 100 and 110 are respectively connected to the main water supply pipe 10 by the control panel. ) And the drain hose 29, the water flowing into the main water supply pipe 10 is cooled while passing through the condenser 22, the heat exchanged cooling water is discharged through the bath hose 29, as a result, the same as the conventional Only the ice maker is operated separately by the method, and ice is produced through the ice making and the ice making process.

On the other hand, as a comparative example, in the conventional technique, that is, during the ice making process, water consumption is increased, so that the operating cost of the ice maker is greatly increased, and condensation and evaporation effects are lowered by cooling the condenser with water supplied from the main water supply pipe. Of course, unlike the increase in energy loss, the present invention can be seen that the total amount of water discharged by heat exchange in the condenser to recover the recycled to the cooling water of the condenser.

In this result, according to the present invention, there is no consumption of cooling water, the operating cost is reduced, and by lowering the temperature of the cooling water, the condensation effect and the evaporation effect are increased, the ice production is increased, and the water pressure is low due to the attachment of the cooling water circulation pump. Not only can it be installed anywhere, but the efficiency of power consumption is improved.

In addition, although specific embodiments of the present invention have been described and illustrated above, it is obvious that the present invention may be variously modified and implemented by those skilled in the art.

Such modified embodiments should not be individually understood from the technical spirit or the prospect of the present invention, and such modified embodiments shall fall within the appended claims of the present invention.

According to the cooling water recovery apparatus of the water-cooled ice maker of the present invention, which is clear from the above description, the whole quantity can be recovered without discarding the water discharged by heat exchange in the condenser of the ice maker and recycled with the cooling water of the condenser, thereby reducing the operating cost and improving the power consumption efficiency. In addition, by lowering the recovered cooling water to an appropriate temperature, the condensation effect and the evaporation effect are increased to enable the production of a large amount of ice as well as the installation of a coolant circulation pump at a low water pressure.

In addition, in case of failure of the unit cooler and the cooling water supply unit, only the ice maker can be operated separately to produce ice, and the maintenance of the ice maker is convenient.
