Description

[0001] CONDENSER COOLING SYSTEM [0002]

The present invention relates to a cooling system for improving the performance of a condenser by spraying water to the condenser.

More specifically, water is allowed to flow inside the pin protection net provided outside the condenser to protect the condenser, so that water flowing in the pin protection net is sprayed to the external condenser, or low pressure To a condenser cooling system in which a circulation pipe through which expanded refrigerant is circulated is inserted.

Generally, a refrigerator includes a compressor, a condenser, an expansion valve, and an evaporator, wherein the condenser functions to condense the compressed heat of the compressor and the refrigerant compressed in the gas state .

This refrigerator is divided into a water-cooled condenser and an air-cooled condenser.

Among them, the water-cooled condenser is excellent in heat transfer effect and is mainly used in a large-capacity freezer. It has an advantage of being able to maintain a constant temperature because the degree of overheating is lower than that of an air-cooled condenser. However, However, there is a drawback that the power of the refrigerator must be turned off for customs work, and the cost is increased.

In addition, the air-cooled condenser is advantageous in that it can be used continuously without stopping the power source because it does not require a tubular operation as compared with a water-cooled condenser, but it has a drawback that it is overheated.

Accordingly, as the frequency of use of the air-cooled condenser increases, the problem of the air-cooled condenser is solved, and a device for spraying water onto the outer surface of the condenser is installed separately to minimize the degree of overheating.

However, a separate water injection device provided in the conventional air-cooled condenser has a problem that water is wasted due to continuous water injection.

In addition, there is a problem that the structure of the condenser itself increases due to the structure in which water is sprayed by providing a separate pipe outside the condenser, thereby increasing the installation area and decreasing the durability.

The condenser 100 functions to cool the high-temperature / high-pressure gas delivered from the compressor by water or air, condense the low-temperature / high-pressure liquid into a liquid at a low temperature / high pressure and send the condensed liquid to the expansion side. Referring to FIG. 2, Pressure refrigerant liquid pipe 160 through which the gas of the high-pressure refrigerant liquid pipe 160 flows.

2, the pin protection net 110 is provided to surround the outside of the condenser 100 to protect the condenser 100. As shown in FIG.

Such a PIN protection net 110 may be in the form of a lattice or alternatively in an " X " shape as shown in the accompanying drawings.

The tube 120 is a space formed inside the pin protection net 110, allowing the fluid to flow through the space.

The tube 120 is formed in a circular tube shape in which the pin protection net 110 itself is hollow to form an internal space of the pin protection net 110 or a separate tube 120 May be provided.

In this case, if a separate tube 120 is provided in the inner space of the pin protection net 110, the tube 120 may be made of a stainless steel or PVC pipe or a pressure tube.

As shown in FIG. 2, the tube 120 may be formed with a plurality of tube ejection openings 121.

The tube ejection port 121 functions to perform a function of performing a function of ejecting the fluid flowing through the tube 120 to the outside of the pin protection net 110 through the tube ejection port 121.

At this time, the direction in which the tube injection port 121 faces may be oriented from the pin protection net 110 toward the direction in which the main body of the condenser 100 is positioned, and water injected through the tube injection port 121 is directed to the condenser 100, The load of the condenser 100 can be reduced.

Further, the water injected through the tube injection opening 121 is injected finely using the atomizing principle to uniformly spray the water on the entire area of the condenser 100, and the ambient temperature can be remarkably lowered by using the principle of evaporation have.

2, the front, rear, left, and right sides of the condenser 100 are entirely enclosed, and the tube 120 through which the fluid flows passes through the pin protection net 110 And a plurality of tube ejection openings 121 may be formed along the fin protecting net 110.

When the water is injected from the plurality of tube injection openings 121 to the upper part of the condenser 100, the water injected upward flows down to the side of the condenser 100 as a whole.

As another example, it is needless to say that the tube injection port 121 may be formed to be spaced apart by a certain distance, as shown in FIG. 3, so as to be uniformly sprayed on the entire side surface of the condenser 100.

Thus, the degree of overlap of the ranges injected from the respective tube injection ports 121 is minimized, so that even a small amount of water can be injected into the entire portion of the side surface of the condenser 100, thereby minimizing unnecessary water consumption.

The condenser cooling system includes a tube 120 through which water flows in the pin protection net 110 for protecting the condenser 100 and a plurality of tube injection openings 121 formed in the tube 120, 120 to the side of the condenser 100, the performance of the condenser can be efficiently improved by absorbing the heat of condensation and lowering the ambient temperature.

On the other hand, the tube injection port 121 formed to spray the water flowing through the tube 120 toward the condenser 100 is exposed to the outside, which may cause a problem that the nozzle portion is clogged when used for a long time.

In order to prevent the above-mentioned problems, the nozzle part (injection tip) 142, which is exposed to the outside so as to spray water, is replaceable, It is possible to prevent the clogging problem beforehand and to cause the water to be sprayed smoothly toward the condenser 100 side.

Such a configuration will be described in detail with reference to Figs. 4 to 10. Fig.

FIG. 6A is a cross-sectional side view of the housing taken along line AA 'of FIG. 4, FIG. 6B is a cross-sectional view of the side of BB' of FIG. FIG. 8 is a view showing another embodiment of the injection hole in the condenser cooling system according to the present invention, and FIG. 9 is a cross-sectional view of the condenser cooling system according to the present invention. 10 is a view illustrating a process of coupling a replaceable pipe to a housing in a condenser cooling system according to the present invention.

The housing 130 is connected to the tube ejection port 121 from the outside of the pin protection net 110 so that water flowing through the tube 120 is transferred to the housing 130. As shown in FIGS. 4 and 5, And a replaceable pipe 140 to be described later are selectively coupled and replaceable so that the transferred water is discharged to the outside through the replaceable pipe 140 to be sprayed to the condenser 100.

That is, the housing 130 functions as a body for allowing the replaceable pipe 140 to be easily replaced, and to allow the water transferred from the tube 120 to be transferred to the replaceable pipe 140 and then discharged to the outside And includes a coupling hole 131, a communication hole 132, a spray hole 133, and a guide groove 134.

The coupling hole 131 is formed in the inside of the housing 130 and is formed in the shape of a circular tube in which the inside of the housing 130 is empty.

This coupling hole 131 provides a space into which the replaceable tube 140 described later is inserted.

Preferably, as shown in FIG. 4, the housing 130 may have a shape that is opened only on one side of the housing 130.

Accordingly, the replaceable pipe 140 is inserted through the space opened to one side and is seated in the coupling hole 131.

6B, the outer circumferential surface of the housing 130 and the coupling hole 131 are partially communicated with each other. The communication hole 132 communicates with the tube injection hole 121, So that the water passed through the communication hole 132 is transferred to the coupling hole 131.

6B, the spray hole 133 performs a function opposite to that of the communication hole 132. Water injected into the coupling hole 131 through the communication hole 132 flows into the spray hole 133 So that the discharged water is sprayed to the condenser 100.

That is, when the replaceable pipe 140, which will be described later, is inserted into the housing 130, the water transferred through the communication hole 132 is discharged to the outside through the replacement pipe 140 through the injection hole 133.

At this time, as shown in the accompanying drawings, the injection hole 133 may be formed so that its width gradually decreases from the outer circumferential surface of the housing 130 toward the inside thereof.

Accordingly, the water that has passed through the exchange tube 140 and discharged through the spray hole 133 spreads in multiple directions and is sprayed to the condenser 100 in a wide area.

The guide groove 134 has a shape elongated in the longitudinal direction of the coupling hole 131 and is formed in a shape widened to the outside of the coupling hole 131 as shown in FIG. 6A.

The guide groove 134 has a connecting hole 141 protruding from the outer circumferential surface of the replaceable pipe 140 in the process of being inserted into the engaging hole 131, To move smoothly along the guide grooves 134. As shown in FIG.

6 (b), the guide groove 134 is elongated in the longitudinal direction of the coupling hole 131, and the guide groove 134 is formed in a portion where one or more tube jetting ports 121 are located, And at least one communication groove 134a may be formed.

The communication groove 134a is formed in the shape of being widened to the outside of the coupling hole 131 together with the guide groove 134. When the replacement pipe 140 is inserted into the coupling hole 131, The connection 141 and the contact member 141a are inserted in the longitudinal direction of the housing 130 along the guide groove 134. When the inserted tube 140 is rotated, The contact member 141 and the contact member 141a are rotated along the communication groove 134a to communicate with the communication hole 132 of the housing 130. [

6B, the connection hole 141 of the replaceable pipe 140 is in communication with the communication hole 132 of the housing 130, and the contact member 141a is in communication with the communication hole 132, So that the water conveyed through the communication hole 132 is not leaked into the coupling hole 131 but flows smoothly into the replaceable pipe 140 through the coupling hole 141. [

According to the design conditions, a heat transfer member 135 connecting the condenser 100 and the housing 130 may be provided.

The heat transfer member 135 transfers the heat to the housing 130 during the heat of the condenser 100 so that the size of the spray hole 132 varies.

7, the injection holes 132 formed in the housing 130 may be formed so that the dissimilar metals B1 and B2 having different thermal expansion coefficients communicate with the inside and the outside of the housing 130, respectively.

The double metal (B1, B2) may be coupled to one end of the outer circumferential surface of the housing 130 so as to be able to bend in a space where the spray holes 132 are formed, and the other metal may not be fixed.

When the high temperature heat is transferred to the housing 130 by the heat transfer member 135 in the course of the heat of the condenser 100 being raised, the double metal B 1 and B 2 are increased in proportion to the temperature change of the housing 130. 7, the temperature of the injection hole 133 is increased so that the size of the injection hole 133 is increased. When the temperature of the injection hole 133 is lowered, So that the size of the injection hole 133 can be reduced.

As another example, referring to FIG. 8, a coil-shaped metal C that blocks the spray holes 132 formed in the housing 130 may be formed.

As shown in FIG. 8, the coil-shaped metal C is made of a material that expands or shrinks in proportion to a changing temperature. The coil-shaped metal C has a narrow space between the coil-shaped metal C and the heat- When the heat of the high temperature is transferred to the housing 130, it expands in proportion to the temperature change of the housing 130, so that the space between the spaces is opened, and more water flows through the space between the spaces, Can be configured to pass through.

7 and 8, the injection hole 132 formed in the housing 130 is expanded or contracted in proportion to the temperature change of the condenser 100 by the heat transfer member 135, When the temperature rises too much, the size of the injection hole 132 becomes larger and a larger amount of water is injected toward the condenser 100, so that the elevated heat of the condenser 100 can be rapidly lowered. In addition, if the temperature rise of the condenser 100 is relatively small, the size of the spray hole 132 is made small in proportion thereto, and a relatively small amount of water is sprayed toward the condenser 100, thereby making unnecessary use of water Can be minimized.

The replaceable pipe 140 is inserted into the coupling hole 131 of the housing 130 and allows water to be passed through the housing 130 and includes a connecting hole 141 and a spray tip 142 .

Since the replaceable tube 140 can be attached to and detached from the coupling hole 131, if the injection tip 142 is clogged, the replaceable tube 140 can be easily replaced and used.

The connector 141 is formed on the other side of the replaceable tube 140 and communicates with the outside so that the replaceable tube 140 is inserted into the engaging hole 131 of the housing 130 And communicates with the communication hole 132 of the housing 130 to provide a space through which water is transferred.

At this time, the connector 141 is protruded from the outer circumferential surface of the replaceable tube 140, and a contact member 141a formed to surround the connector 141 may be provided.

When the replaceable pipe 140 is rotated in the coupling hole 131 of the housing 130, the contact hole 141a of the contact hole 141a of the housing 130 132 so as to prevent the water flowing through the communication hole 132 and the connection port 141 from flowing out.

Thus, the water that has passed through the communication hole 132 and the connection hole 141 is transferred to the inner space of the replaceable pipe 140.

The injection tip 142 is formed at one side of the replaceable pipe 140 to perform a function of discharging the water transferred into the replaceable pipe 140 to the outside.

6A and 6B, when the replaceable tube 140 is rotated in the state of being inserted into the coupling hole 131 of the housing 130, And communicates with the holes 133 to allow the water contained in the replaceable pipe 140 to be discharged to the outside through the injection tip 142 and the injection hole 133.

According to the design conditions, the handle 143 can be further provided which can easily grip the replaceable pipe 140.

The handle 143 allows the replaceable tube 140 to be inserted into the housing 130 and allows the inserted replaceable tube 140 to be rotated easily.

10, a replaceable tube 140 is inserted into the coupling hole 131 of the housing 130, and the insertion tube 140 is inserted into the coupling hole 131 of the housing 130, The connection 141 and the contact member 141a protruding from the outer circumferential surface are inserted along the guide groove 134 of the housing 130 and the connection 141 and the contact member 141a are inserted into the communication groove 141. [ (134a) is formed. The connection 141 and the contact member 141a are then moved along the communication groove 134a so that the connection 141 of the replaceable pipe 140 and the connection 141 of the replaceable pipe 140 are rotated, The tip 142 is positioned so as to be in communication with the communication hole 132 and the spray hole 133 of the housing 130 so that the water transferred from the tube spray hole 121 flows through the communication hole 132, ), The inner space of the replaceable tube 140, the injection tip 142, and the spray hole 133 in this order.

11 is a view showing an example in which a blocking wall is provided in the condenser cooling system according to the present invention.

On the other hand, since the water sprayed to the condenser 100 is finely sprayed by the sprayer principle, it may not be sprayed to the correct position due to the influence of wind blowing from the outside.

11, a blocking wall 150 may be provided between the condenser 100 and the PIN protection net 110 to minimize the influence of wind.

The blocking wall 150 covers the side surface with respect to the spraying direction of the water sprayed to the condenser 100 so as to minimize the influence of wind blowing from the outside so that the function of spraying water to the correct position on the surface of the condenser 100 And may be in the form of a plate.

Preferably, the blocking wall 150 may be provided between the corner portion of the pin protection net 110 and the corner portion of the condenser 100, as shown in FIG. 11

For example, since the transverse cross section of the condenser 100 is formed in a rectangular shape as a whole, the blocking wall 150 may be provided at each corner, and may be formed of four as shown in FIG.

Accordingly, it is possible to minimize the scattering of the water sprayed to the outside of the housing 130 by cutting off the wind blowing from the side, and to induce the spraying to the spraying region of the condenser 100.

At this time, the blocking wall 150 can be detachably attached.

FIG. 12 is a perspective view showing an example in which a circulation pipe is provided in the condenser cooling system according to the present invention, and FIG. 13 is a view showing another example of the circulation pipe in the condenser cooling system according to the present invention.

It is needless to say that the circulation pipe 170 may be configured to pass between the high-pressure refrigerant liquid pipes 160 having a plurality of S-shaped shapes according to design conditions.

12, the circulation pipe 170 may be formed so as to sequentially pass the U-shaped portion of the high-pressure refrigerant liquid pipe 160 having a plurality of S-shaped shapes.

The circulation pipe 170 is internally provided with a closed space so that the low-pressure expanded refrigerant can be circulated therein.

Accordingly, as shown in the accompanying drawings, the circulation pipe 170 through which the low-pressure expanded refrigerant circulates is closely located to the U-shaped portion of the high-pressure refrigerant liquid pipe 160, so that it passes through the high-pressure refrigerant liquid pipe 160 It is possible to rapidly decrease the temperature by increasing the contact area with the high-temperature / high-pressure gas.

The circulation pipe 170 is connected to the high-pressure refrigerant liquid pipe 160 (see FIG. 13) so as to increase the area where the U-shaped portion of the high-pressure refrigerant liquid pipe 160 closely contacts the circulation pipe 170, And then passes through the U-shaped portion.

Here, as shown in FIG. 13, the number of times the U-shaped portion of the high-pressure refrigerant liquid pipe 160 is wrapped may be configured to be wrapped once or wrapped twice or more.

By maximally increasing the area in which the high pressure refrigerant liquid pipe 160 and the circulation pipe 170 are in close contact with each other, the temperature of the high temperature / high pressure gas delivered from the compressor 400 through the high pressure refrigerant liquid pipe 160 is rapidly lowered, / High-pressure liquid, as well as to reduce the load on the condenser 100, thereby effectively improving the performance.

In the condenser cooling system constructed as described above, the pin protection net or the circulation pipe 170 may be formed of a copper pipe or a urethane pipe.

The circulation of the water spray of the tube jet opening 121 and the circulation pipe 170 is performed simultaneously with the discharge of the fluid from the tube jet opening 121 or the circulation of the expanded refrigerant of low pressure from the circulation tube 170, May be configured to have an operating point.

That is, the operating point functions to control the operation of injecting water from the tube injection port 121 and the operation of circulating the expanded refrigerant at a low pressure from the circulation pipe 170, Water circulation in the circulation pipe 170 can be performed.

For example, when the measured temperature is equal to or higher than 35 ° C, the fluid is sprayed from the tube injection port 121 or circulated Pressure expanded refrigerant may be circulated from the pipe 170 or fluid may be injected from the tube injection port 121 and the low-pressure expanded refrigerant may be circulated from the circulation pipe 170. [

Another example is to measure the gas temperature of the high temperature / high pressure discharged from the compressor 400 and to cause the fluid to be injected from the tube injection port 121 or to discharge the fluid from the circulation pipe 170 It is possible to cause the low-pressure expanded refrigerant to circulate or the fluid to be injected from the tube injection port 121 and to circulate the low-pressure expanded refrigerant from the circulation pipe 170. [

At this time, a separate temperature sensor (not shown) for measuring the temperature of the low temperature / high pressure refrigerant condensed in the condenser 100 and the temperature of the high temperature / high pressure gas discharged from the extruder 400 may be provided have.

It is preferable that the temperature sensor is installed on the exhaust side of the condenser 100 and that the temperature sensor is installed on the discharge side of the compressor 400.

As another example, when the operation current value is 110% or more of the set operation current value after the operation current value of the compressor 400 is measured, the fluid is injected from the tube injection hole 121 or the circulation pipe 170 Or the fluid is injected from the tube injection port 121, and the low-pressure expanded refrigerant is circulated from the circulation pipe 170. In this case, the low-pressure expanded refrigerant is circulated.

When the compressor 400 is overloaded, heat is generated. Accordingly, after the operation current value of the compressor 400 is measured, operation of fluid injection or circulation of the refrigerant can be minimized.

For example, measuring the operating current burst of the compressor 400 may comprise an electronic overload relay (EOCR).

FIG. 14 is a schematic structural view showing an example in which a water softener is provided in the condenser cooling system according to the present invention.
