The present invention relates to a water-cooled air conditioner having a compressor 25, a condenser 30, and an evaporator 26 as main parts on a refrigerant circulation path, and in which the downflow cooling water and the upflow cooling air heat exchange with each other. . The refrigerant introduced from the compressor 25 to the condenser 30 is condensed by exchanging heat with the cooling water and the cooling air at the same time. After entering the evaporator 26 through the capillary tube 29, the refrigerant is sent to the compressor 25 and circulated. The condenser 30 is provided with a pump 22 for circulating the cooling water and a blowing fan 24 for flowing the cooling air. At the rear of the evaporator 26, a blowing fan 28 in the form of a sirocco fan is installed.

According to the present invention, as shown in FIG. 3, the evaporator 26 may have a straight shape in addition to the c-shape, and the installation direction may be partially modified. In this way, although the intake and exhaust paths of the cooling air and the cooling air moving inside the enclosure 10 vary slightly depending on the shape and position of the evaporator 26, the cooling air and the cooling air moving inside the enclosure 10 are different. In the common intake and exhaust path, the intake window 15 and the exhaust window 16 are provided on the path of the cooling air, and the intake window 17 and the exhaust pipe 18 are provided on the path of the cooling air.

In addition, according to the present invention is provided with a receiving means to accommodate the main portion of the refrigerant circulation path in a mutually independent space. More specifically, as shown in FIG. 1, three independent spaces may be formed using one enclosure 10 and two walls 13 and 14. Of course, the number of enclosures 10 and walls 13 and 14 can be variously changed, but FIG. 1 is preferable when considering the convenience of installation and management. The enclosure 10 is treated in whole or in part with sound insulation and insulation.

In the enclosure 10 of FIG. 1, the condenser 30 is accommodated in an independent space on the left side of the wall 13, and the evaporator 26 and the blower fan 28 are accommodated in the right side of the wall 13. In the space on the right side of the other wall 14, the compressor 25 is separately accommodated. When the compressor 25 is accommodated in an independent space according to the storage means of the present invention, the operation noise of the air conditioner is greatly reduced.

In addition, according to the present invention, a heat exchange means having simultaneous cooling water and an air circulation path on the condenser 30 is used. The condenser 30 includes a pump 22 for circulating cooling water, a water tank 20 for storing the cooling water, a level switch for detecting the level of the water tank 20, and a blower fan 24 for flowing cooling air. . The heat exchange means is located at the intersection of the downflow cooling water and the upflow cooling air as a key element of the condenser 30. A spray 23 is provided on the upper side of the heat exchange means to evenly distribute the cooling water, and a scattering prevention plate 33 in the form of a metal lath wire mesh is installed on the upper side of the spray 23 to prevent backflow of the cooling water droplets. In addition, the water supply pipe 21 is connected to the pipe to supplement the cooling water from the outside for the vitalization of the air conditioner (the configuration of the water supply pipe may be omitted), and the hot air discharged from the blower fan 24 is discharged to the outside The exhaust pipe 18 is connected to the pipe. Specific configuration and operation of such heat exchange means refer to FIGS. 4 to 6 to be described later.

In addition, according to the present invention, a condensate bottle 27 is installed at the lower end of the evaporator 26 to collect condensate. The condensate bottle 27 is connected to join the cooling water on the condenser 30. The condensation tank 27 has a box structure in which the upper portion is opened, has an opening larger than the area of the lower end of the evaporator 26, and is connected in an inclined state so as to descend downward to the water tank of the condenser 30 through the cooling water pipe 32 at the bottom. (See Figure 9).

Figure 4 is an illustration showing a variety of condenser according to an embodiment of the present invention, Figure 5 is an illustration showing a variety of condenser according to another example of the present invention, Figure 6 is an illustration showing a condenser according to another example of the present invention .

4A to 4D, the heat exchange means of the present invention is connected to the air pipe 40 constituting the refrigerant circulation path to the inner cylinder 41 and the outer cylinder 42 in series or in a double row.

As shown in FIG. 4A, the condenser 30 is installed to pass water in the downward direction of the spray 23, and the condenser 30 includes a flow path of a refrigerant that is heat-exchanged with the water passing therethrough. The water rising upward by the pump 22 in the water tank 20 falls through the spray 23, and all the water falling passes through the condenser 30 and is collected again in the water tank 20 in the downward direction. do. The refrigerant is circulated to the outside through a flow path formed in the air supply pipe 40 and constitutes a cooling cycle.

It is preferable to use the same form as the above-mentioned splash prevention plate 33 for the fall delay plate 35 which is usually disposed together with the air supply pipe 40. However, such a fall retardation plate 35 does not necessarily need to be installed, and the scattering prevention plate 33 also has a possibility that water droplets are discharged upward through the height adjustment of the spray 23 and the blowing fan 24 as shown in FIG. 4B. It can also be omitted by blocking it in advance.

In FIG. 4A, a single air pipe 40 is brazed at both ends of the inner cylinder 41 and the outer cylinder 42 so as to form a double wall of a constant space, and a bolt 43 having a through hole at its center communicates with the double wall. It is joined to the upper and lower ends so as to. In order to improve the heat exchange efficiency of the refrigerant, the corrugated plate 44 having a louver cut groove may be inserted in the space of the double wall. Of course, even if a cooling fin is formed on the outer surface of the outer cylinder 42, the same effect can be achieved. The air supply pipe 40 is used in a quantity designed according to the cooling capacity of the air conditioner, as shown in FIG. 4B by connecting a separate conduit 46 on the bolt 43 can also form a refrigerant circulation path.

The plurality of airborne pipes 40 may be arranged vertically, but may be arranged horizontally. In the case of the horizontal arrangement as shown in FIG. 4B, since the coolant is difficult to flow in the center, the coolant pipe 45 may be additionally inserted into the center of the airborne pipe 40. The coolant pipe 45 branches on the pipe from the pump 22 to the spray 23. In FIG. 4C, instead of reducing the size of the air pipe 40 ′, a configuration in which a plurality of air pumps 40 are integrated into the air pump 48 is also possible. Cooling water flowing out of the air pipes 40 'is branched and supplied upstream of the spray 23, like the coolant pipe 45 of FIG. 4B.

On the other hand, in any of the above cases, the plurality of air pipes 40 and 40 'may be connected in series or in parallel circuits. Referring to FIG. 4D, even when the air pipes 40 'are connected in parallel, both ends of the circuit are respectively formed in the form of a single pipe like the reference numerals 46a and 46b, respectively. Connected with

5a to 5i, the heat exchange means of the present invention is connected to the meandering pipe 50 having a connecting conduit 52 at both ends is connected in multiple layers. As shown in FIG. 5A, the condenser 30 is installed to pass water in the downward direction of the spray 23, and the condenser 30 includes a flow path of a refrigerant that is heat-exchanged with the water passing through. The water rising upward by the pump 22 in the water tank 20 falls through the spray 23, and all the water falling passes through the condenser 30 and is collected again in the water tank 20 in the downward direction. do. The refrigerant is circulated to the outside through a flow path formed in the meandering tube 50 and constitutes a cooling cycle.

Usually, the fall delay plate 35 disposed together with the meandering pipe 50 preferably uses the same shape as the above-mentioned shatterproof plate 33. However, the fall retardation plate 35 does not necessarily need to be installed, and the scattering prevention plate 33 also has a possibility of discharging upward through the height adjustment of the spray 23 and the blowing fan 24 as shown in FIG. 5B. It can also be omitted by blocking it in advance.

In FIG. 5C, the meandering pipe 50 is a continuous U-shaped meandering structure tube. The installation position is the same as that of the airborne pipe 40 described above, and may be stacked up and down using the connecting conduit 52 at both ends. . It is also possible to further include a heat sink (not shown) having the same function as the above-described corrugated plate 44 horizontally or vertically between the layers on which the meander tube 50 is stacked.

5D to 5I illustrate various forms of the meandering tube 50, in which a plurality of internal spaces or outer surfaces are partitioned to increase the heat transfer area. More specifically, as shown in FIGS. 5D, 5E, 5F, 5G, and 5I, the partition 55a may be configured such that the inner space of the meandering tube 50 formed in an elliptical shape is divided into a plurality, and as shown in 5G. The heat dissipation fins 55d may be further provided on the outer surface, and the coolant may flow between the inner spaces of the meandering tube 50 in which the porous pins 55e are inserted as in 5i. That is, it may be partitioned to form a partition by installing a plurality of partitions, as shown in 55a, or may be partitioned to form a layer by inserting a small tube such as 55b, inserting a fine mesh or porous pin, such as 55c and 55e It may be. While the heat transfer area increases toward the latter, the flow resistance of the refrigerant also increases, so it is suitable for a system to which a large-capacity compressor 25 is applied. The configuration of forming a plurality of heat radiation fins 55d on the outer surface of the meandering tube 50 in FIG. 5G is equally applied to FIGS. 4A and 5A. However, the heat dissipation fins 55d have a very good heat transfer efficiency, but there is a problem of corrosion, and thus the heat dissipation fins 55d may be omitted.

In addition, Figure 6a shows the internal space of the meandering tube 50 formed in a circular or deformed form. That is, the inner space of the meandering tube 50 formed in a circular shape as shown in FIG. 6A may be left empty, or the partition 55a or the porous pin 55e may be inserted into the inner space of the meandering tube 50 as shown in FIGS. 6B and 6C.

On the other hand, Figure 7a shows that the fall delay plate 35 is installed between the meander pipe 50, the fall delay plate 35 increases the contact surface of water and air to improve heat exchange efficiency Let's do it. In addition, the fall retardation plate 35 formed in the meandering tube 50 of FIG. 7B has the same shape as the above-mentioned shatterproof plate 33, which also helps improve heat exchange efficiency. However, in place of the fall delay plate 35 illustrated in FIG. 7B, the heat dissipation fin 55d or the porous fin 55e may be replaced.

Referring to FIG. 8, the heat exchange means of the present invention is connected to a plurality of grating cylinders 60 that form a zigzag flow path by the diaphragm 65. As shown by the partial incision, the lattice cylinder 60 which forms a flow path of the refrigerant in a zigzag form by the partition wall 65 is installed downward of the spray 23. Compared to connecting the airborne pipe 40 or the meandering pipe 50 one by one, the installation work is easy and advantageous in terms of productivity. However, the heat transfer capacity is reduced due to the relatively low heat transfer area. Of course, it is also possible to accommodate the corrugated plate 44 of FIG. 4A described above on the zigzag flow path formed by the partition wall 65.
