The present invention relates to a mobile water-cooled air conditioner, and more particularly, horizontal partitions are installed in the interior of the air-conditioning housing and partitioned into an upper space and a lower space, an evaporator is installed in the upper space, and a water-cooled condenser in the lower space. Although installed in the horizontal direction inside the condenser case consisting of a predetermined plastic housing, the heat exchanger and the blower fan of the water-cooled condenser, so that the flow of the cooling water and the cooling air supplied to the heat exchanger to each other to improve the cooling efficiency The present invention relates to a mobile water-cooled air conditioner that minimizes noise.

An air conditioner is a device that uses evaporative heat to take heat away from the surroundings when the liquid evaporates. Air conditioners generally include evaporators and condensers. The condenser is composed of a compressor, a condenser (condensation heat exchanger), a blower fan to cool the refrigerant, and the evaporator is composed of an evaporator (evaporator heat exchanger), a cooling fan and a capillary tube to cool the indoor air.

Such air conditioners are classified into separate air conditioners and integrated air conditioners according to a combination of an evaporator and a condenser. In the separate air conditioner, the evaporator and the condenser each have separate housings. In addition, an indoor unit in which the evaporator is installed is installed indoors, and an outdoor unit in which the condenser is installed is installed outdoors. The indoor unit and the outdoor unit are connected via a refrigerant pipe of a predetermined length. Therefore, a separate air conditioner has an advantage of maintaining a quiet indoor atmosphere because a condenser that generates heat and noise is installed outdoors, but cannot freely move an indoor unit or an outdoor unit. On the other hand, the integrated air conditioner is provided with both an evaporator and a condenser in one housing. Therefore, the integrated air conditioner has the advantage of free movement, but because the condenser that generates heat and noise is located in the room, there is a problem that the cooling efficiency is low and it is difficult to maintain a quiet indoor atmosphere.

The present invention relates to a mobile water-cooled air conditioner that is not only free of movement but also has high cooling efficiency and little noise. Conventional mobile air conditioners use a large amount of indoor air to cool a refrigerant. The air-cooled air conditioner is less energy efficient as the amount of indoor air used as cooling air increases. Therefore, in order to increase the energy efficiency of the mobile air conditioner, it is required to reduce the amount of indoor air used for cooling the refrigerant. In order to solve this problem, a water-cooled condenser has been proposed. The water-cooled condenser cools the refrigerant by using both cooling water and cooling air at the same time, thereby reducing the amount of indoor air discharged to the outside.

1 and 2 are a schematic perspective view and a side view showing an example of a conventional mobile water-cooled air conditioner, Figure 3 is a schematic side view showing a water-cooled condenser used in the conventional mobile water-cooled air conditioner. As shown, the conventional mobile water-cooled air conditioner 100 is installed on the housing 101, the evaporator 110 and the water-cooled condenser 130 is installed below. At this time, the drain pan 117 is horizontally installed in the housing 101 to partition the upper space (a) and the lower space (b). However, the drain pan 117 is provided only for the purpose of collecting condensate generated from the evaporator 110, and thus does not substantially separate or seal the upper space (a) and the lower space (b). That is, in the conventional mobile water-cooled air conditioner 100, not only the flow of air is free between the upper space (a) and the lower space (b) but also the noise generated in the lower space (b) is not blocked and the upper space ( delivered to a).

And the evaporator 110 is installed in the upper space (a) of the housing 101 is a cooling fan 113, a plurality of heat exchangers 115 for the evaporator installed to surround the cooling fan 113, and It consists of a drain pan 117 installed in the lower part of the heat exchanger 115 for an evaporator. In addition, the water-cooled condenser 130 installed in the lower space (b) of the housing 101 is a compressor 133, an auxiliary water tank 135 installed on one side of the compressor 133, and the auxiliary water tank 135 It consists of a water-cooled condenser 140 installed on one side.

On the other hand, the water-cooled condenser 140, as shown in Figure 3, the cooling water tank 141 for storing the cooling water, the circulation pump 142 for circulating the cooling water, and the air blow fan 143 to intake the cooling air to the top And a condenser heat exchanger 144 having a cooling water and an air circulation path at the same time, and a sprinkler 145 installed on the condenser heat exchanger 144 to evenly distribute the cooling water supplied by the circulation pump 142. And a scattering prevention plate 147 installed between the sprayer 145 and the blower 143 to prevent water droplets from being discharged together with the discharged air. In addition, reference numeral 146 denotes a cooling water circulation pipe through which cooling water is circulated, 148 is an exhaust hose through which heat-exchanged hot and humid exhaust air is discharged, and 149 is a refrigerant circulation pipe through which refrigerant is circulated.

As such, the water-cooled condenser 140 according to the prior art has a cooling water and cooling air in a counterflow type, that is, the cooling water is lowered from the top to the bottom of the heat exchanger 144 for the condenser, and the cooling air is the heat exchanger 144 for the condenser. From bottom to top. This counter type decreases the heat exchange efficiency because the heated hot exhaust air warms the cooling water sprayed from the sprinkler 145 while moving upward from the bottom of the heat exchanger 144 for the condenser. Therefore, the amount of cooling air and cooling water used is also increased. In addition, when the amount of the cooling air is increased, the amount of indoor air discharged to the outside through the exhaust hose 148 increases, thereby decreasing energy efficiency. In addition, the energy consumption is increased by increasing the operating time of the circulation pump 142 in order to increase the usage amount of the cooling water.

In addition, the conventional water-cooled condenser 140 is provided with a scattering prevention plate 147 to prevent the water droplets contained in the discharged air discharged through the exhaust hose 148, the scattering prevention plate 147 is discharged As the design capacity of the blower fan 143 is increased by increasing the flow resistance of the air, energy consumption increases as well as the noise is aggravated.

In addition, in the conventional mobile water-cooled air conditioner 100, as shown in FIG. 2, a plurality of air inlets 105 are installed at the lower end of the housing 101 to supply cooling air to the lower part of the heat exchanger 144 for the condenser. Therefore, the noise generated by the blower fan 143 and the compressor is radiated into the room through the air inlet 105, thereby increasing the room noise. In addition, in the conventional mobile water-cooled air conditioner 100, since the exhaust hose 148 and the blower fan 143 are installed adjacent to each other, the noise of the blower fan 143 radiates to the outside through the exhaust hose 148 together with the exhaust air. Therefore, there was a problem that the generation of noise increases.

The present invention has been made to solve the above-mentioned problems of the prior art, the main object of the present invention is to minimize the amount of indoor air discharged to the outside through the exhaust hose to increase the cooling efficiency and energy efficiency at the same time to minimize the generation of noise It is to provide a water-cooled air conditioner.

It is to provide a portable water-cooled air conditioner to minimize.

The present invention also provides a predetermined horizontal plate inside the air conditioner housing to partition the housing into an upper space and a lower space, and also incorporates a heat exchanger and a blower fan of the water-cooled condenser into a sealed condenser case, and installs a water-cooled condenser. The lower space of the housing is to provide a portable air-cooled air conditioner does not form a cooling air inlet that is directly introduced from the room so that the noise generated from the blower and the compressor is not radiated into the room.

In addition, the present invention forms an air passage having a reduced diameter between the condenser heat exchanger and the blower fan installed in the condenser case made of a plastic housing in the horizontal direction, so that the noise generated in the blower fan is removed from the condenser case in which the heat exchanger for the condenser is installed.

The upper plate 17 of the housing 11 is formed with a cold air vent 18 through which the cooled air flows out. The cold air vent 18 is provided with a rotatable grill 19 to adjust the flow and direction of the cold air. In addition, air inlets 22 and 23 are formed in the front plate 12 and the rear plate 13, respectively. In addition, a predetermined display unit 25 is installed on the top plate 17 of the front panel 12.

In addition, two rotatable wheels 27 are installed at the lower end of the housing 11. At this time, the lower end of the left and right side plate 14, 15 is formed with a settling groove 28 of a predetermined depth so that the wheel 27 is settled. The wheels 27 are installed on the rear side of the housing 11. In addition, the front of the housing 11 is provided with a leg 29 of a predetermined height. Therefore, when moving the mobile water-cooled air conditioner (1) by holding a predetermined handle 26 formed on the rear of the housing 11 is moved to the top tilted backwards. On the other hand, components such as a compressor installed in the housing 11 can be moved further by placing the center of gravity of the mobile water-cooled air-conditioning (1) to the rear side of the housing (11). In addition, the wheel 27 has a size that can easily cross the threshold or the like.

6 to 8, the interior of the housing 11 is partitioned into an upper space A and a lower space B by a horizontal plate 40. The horizontal plate 40 is fixed to the inner side of the front and rear plates 12 and 13 and the left and right side plates 14 and 15 of the housing 11. Therefore, the inside of the housing 11 is separated into the upper space (A) and the lower space (B) by the horizontal plate 40. That is, the mobile water-cooled air conditioner 1 according to the present invention is greatly limited in the air flow and noise transmission between the upper space (A) and the lower space (B).

According to the present invention, an air duct 41 having a predetermined size is opened at the center portion of the horizontal plate 40. Therefore, the indoor air introduced into the upper space (A) can move to the lower space (B) only through the air oil tool (41). That is, in the mobile water-cooled air conditioner 1 according to the present invention, the upper space A and the lower space B are substantially closed except for the air oil tool 41 formed in the horizontal plate 40. In addition, the air tool 41 is provided with a noise blocking means to prevent the noise generated in the lower space (B) to be radiated to the upper space (A).

 In addition, the evaporator 50 is installed in the upper space A defined by the horizontal plate 40. The evaporator 50 has a crossflow cooling fan 51 installed on the left and right plates 14 and 15 and a plurality of evaporator heat exchangers arranged in a U-shape to surround the lower end of the cooling fan 51. Group 53, a drain pan 55 installed under the evaporator heat exchanger 53 to collect condensate, and a cold air passage 52 formed between the cooling fan 51 and the cold air vent 18. It is configured to include. In the space between the cold air passage 52 and the upper plate 17, a controller 54 for controlling the mobile water-cooled air conditioner 1 as a whole is installed.

The drain pan 55 is installed on the upper portion of the horizontal plate 40 to be spaced apart at a predetermined interval. In this case, both ends of the drain pan 55 are fixed to the left and right plates 14 and 15. In addition, an air induction passage 42 is formed between the bottom surface of the drain pan 55 and the air induction tool 41 formed on the horizontal plate 40. The air induction passage 42 is formed by three surfaces of the air induction tool 41 formed on the horizontal plate 40, that is, vertical blocking walls 56 of predetermined heights respectively installed on three surfaces except the rear side. Therefore, the indoor air introduced into the upper space (A) is guided to the lower space (B) through the air induction passage (42). A sound absorbing plate 57 having a predetermined thickness is attached to an inner surface of the vertical blocking wall 56 forming the air induction passage 42.

Subsequently, a water-cooled condenser 70 is installed in the lower space B defined by the horizontal plate 40. At this time, the lower space (B) is completely sealed except for the air tool 41 formed in the horizontal plate (40). Therefore, the noise generated in the lower space B is not directly radiated to the outside. As such, the present invention minimizes the direct emission of noise into the room by enclosing the lower space (B) where noise is severe and minimizes the amount of air used by allowing the indoor air to flow in a limited way through the air induction passage (42). .

As shown in FIG. 7, the water-cooled condenser 70 includes a compressor 71, a blower fan 73, a coolant tank 75, an auxiliary tank 76, and a heat exchanger 61 for a condenser. do. The compressor 71 is installed perpendicular to the lower plate 16 of the housing 11. The compressor 71 is embedded in a metal enclosure to minimize heat and noise. The compressor 71 communicates with the evaporator heat exchanger 53 and the condenser heat exchanger 61 through a predetermined refrigerant pipe 72. In addition, one side of the compressor 71 is provided with a rectangular cooling water tank 75 made of a plastic enclosure. In addition, an auxiliary tank 76 for supplying cooling water to the cooling water tank 75 is installed at an upper portion of the compressor 71. The auxiliary water tank 76 is formed with a coolant injection tube 761. In addition, a condenser case 60 having a condenser heat exchanger 61 and a blower fan 73 facing the horizontal direction is installed at an upper portion of the cooling water container 75.

First, as shown in FIGS. 9 and 10, the cooling water container 75 formed of a plastic housing includes a rectangular housing 751 and a lid 752 coupled to an upper surface of the housing 751. The housing 751 and the lid 752 are tightly coupled through a predetermined coupling means 753. And the lid 752 is formed with a water supply port 754, the water supply hose 81 is connected to the auxiliary tank 76 is installed. The lid 752 is provided with a coolant drain port 756 corresponding to a coolant drain port 651 formed on the bottom surface of the condenser case 60 to be described later. In addition, a condensate inlet 757 to which the drain pipe 59 is coupled is formed at one side of the lid 752. In addition, the one side of the housing 751 is formed with a circulation pump installation port 758 is provided with a circulation pump 77 for circulating the cooling water. A plurality of fastening portions 759 are integrally formed at the lower edge of the housing 751 to fix the housing 751 to the lower plate 16 of the housing. At this time, a predetermined vibration pad for absorbing the vibration of the cooling water tank 75 is interposed at the lower end of the fastening portion 759.

Subsequently, a condenser case 60 is installed at an upper portion of the cooling water tank 75. The condenser case 60 includes an upper case 63 and a lower case 65 as shown in FIGS. 8, 9, and 10. In the condenser case 60, a heat exchanger installation unit 611 in which at least one condenser heat exchanger 61 is installed, and a blower fan installation unit 612 in which the blower fan 73 is installed are formed to a predetermined size. Is formed. In addition, a ventilation passage 613 is formed between the heat exchanger mounting portion 611 and the blower fan mounting portion 612 to narrow the tube diameter. The blow passage 613 not only guides the air blown from the blower fan 73 but also prevents the cooling air and the coolant from flowing back. In addition, since the heat exchanger installation unit 611 has a relatively large area, the noise generated in the blower fan 73 is absorbed by the heat exchanger installation unit 611. In the present embodiment, the heat exchanger mounting portion 611 and the blower mounting portion 612 are integrally formed, but in some cases, the heat exchanger mounting portion 611 and the blower mounting portion 612 are manufactured separately. Can then be airtightly combined.

And the heat exchanger 61 for the condenser installed in the heat exchanger installation portion 611 consists of a ribbon-shaped cooling tube bent in a zigzag form, and a cooling fan provided between the cooling tubes. At this time, one side of the heat exchanger 61 for the condenser is provided with a gas-liquid separation tube 62 is enlarged in diameter. The gas-liquid separation tube 62 prevents the liquid refrigerant from flowing into the evaporator. The blower fan 73 installed in the blower fan installation unit 612 is a sirocco blower fan, and the driving motor 74 of the blower fan 73 is formed in the upper portion of the blower fan installation unit 612. It is installed in the tooth 613. In addition, an air inlet 615 of a predetermined size through which air is introduced from the lower space B is opened at the bottom of the blower fan mounting unit 612.

As described above, the heat exchanger 61 and the blower fan 73 for the condenser of the present invention are provided to face the horizontal direction in the condenser case 60. Therefore, the cooling air blown by the blower fan 73 is blown to the heat exchanger 61 for a condenser through the blower passage 613. And the upper part of the heat exchanger 61 for the condenser is provided with a sprinkler 67 for spraying the cooling water. The sprinkler 67 is connected to the cooling water pump 77 through the cooling water supply hose 82. Therefore, the cooling water sprinkled by the sprinkler 67 is sprinkled from the top of the heat exchanger 61 to the bottom. Therefore, the flow of the cooling water sprayed from the sprinkler 67 and the flow of the cooling air blown by the blower 73 are orthogonal to each other in the heat exchanger 61 for the condenser.

On the other hand, the condenser case 60 is composed of an upper case 63 and a lower case 65, the upper case 63 and the lower case 65 is hermetically coupled through a predetermined coupling means (653). have. On the upper surface of the upper case 63, a refrigerant pipe fitting port 631 is formed, in which a refrigerant pipe 72 connected to the compressor 71 and the heat exchanger 53 for the evaporator is installed. The coolant pipe connector 632 is provided to easily install the coolant pipe 72. In addition, the upper case 63 is provided with an exhaust port 633 for discharging the high-temperature exhaust air heat exchanged with the condenser heat exchanger 61, the elbow type exhaust pipe 634 is installed in the exhaust port 633. do. And the end of the exhaust pipe 634 is connected to the exhaust hose 83 of the corrugated pipe form. One side of the upper case 63 is formed with a cooling water supply port 635 in which a cooling water supply hose 82 connected to the cooling water pump 77 is installed.

In addition, a coolant drain 651 is formed at a bottom of the lower case 64 to drain the high temperature coolant exchanged with the condenser heat exchanger 61. The coolant drain port 651 is formed to correspond to the coolant circulation port 756 formed on the upper surface of the coolant tank 75. In addition, a plurality of 'fastening parts 659' are integrally formed at the lower end magnetic field of the lower case 64 to fix the condenser case 60 to the upper surface of the cooling water container 75. At this time, the lower end of the fastening part 659 is preferably provided with a vibration pad for absorbing the vibration of the condenser case 60.

Subsequently, an auxiliary tank 76 for supplying cooling water is provided at one side of the lower space B, preferably at the top of the compressor 71. The auxiliary tank 76 is a plastic cylinder of a predetermined size, and a water injection pipe 761 for injecting water protrudes to a predetermined length at an upper portion thereof. In the lower portion of the auxiliary tank 76, a flexible water supply hose 81 is in communication with the cooling water tank 75.

On the other hand, the cooling water tank 75 is formed with cooling water adjusting means 90 for controlling the flow of the cooling water supplied from the auxiliary tank 76. The cooling water adjusting means 90 is a bottle-shaped guide tube 91 installed in the cooling water container 75, and the floating body 93 installed in the guide tube 01 to be movable up and down. Is done. In this case, a plurality of through holes 94 are drilled in the guide tube 91 to allow the coolant to enter and exit. And the upper portion of the guide tube 91 is formed so that the inlet portion 95 to which the water supply hose 81 is coupled to protrude upward. In addition, the lower end of the guide tube 91 is closed so that the floating body 93 does not escape. At this time, the upper end of the floating body 93 and the inner circumferential surface of the guide tube 91 is formed in the same shape so as to be in close contact with each other.

Therefore, when the water level inside the cooling water tank 75 is lowered, the floating body 93 is lowered. Then, when the water level is lowered and the upper end of the float 93 is located below the through hole 94 formed in the outer circumferential surface of the guide tube 91, the coolant in the auxiliary tank 76 has an inner circumferential surface of the guide tube 91. After being introduced into the gap between the float 93 and the through-hole 94 is supplied to the cooling water tank (75). On the contrary, when the water level of the cooling water tank 75 is increased, the floating body 93 is raised to block the through hole 94 so that the supply of cooling water is stopped. As such, the mobile water-cooled air conditioner 1 according to the present invention may automatically adjust the supply of cooling water using the cooling water adjusting means 90.

Hereinafter, the operation of the mobile water-cooled air conditioner 1 according to the present invention will be described with reference to FIG. 12.

The mobile water-cooled air conditioner 1 according to the present invention includes a circulation flow of refrigerant passing through the compressor 71, the heat exchanger 61 for the condenser, and the heat exchanger 55 for the evaporator, and a blower 73, a heat exchanger for the condenser. The flow of the cooling air through the 61 and the exhaust hose 83, and the circulation flow of the cooling water through the cooling water tank 75, the cooling water pump 77, the sprinkler 67 and the heat exchanger 61 for the condenser. Cools indoor air through

As shown in the mobile water-cooled air conditioner 1 according to the present invention, the flow of the cooling air blown from the blower fan 73 and the flow of the cooling water sprayed from the sprinkler 67 are orthogonal in the heat exchanger 61 for the condenser. do. Therefore, the cooling air blown by the blower fan 73 comes into contact with the descending cooling water and then hits the rear wall of the condenser case 60 and then rises and is discharged to the outside through the exhaust hose 83. As described above, the present invention can prevent the cooling water from being heated by the heat-exchanging high-temperature cooling air because the cooling air and the cooling water are in contact with each other at right angles, thereby greatly reducing the amount of cooling water and cooling air used. In addition, in the present invention, when the cooling air hits the rear wall of the condenser case 60, since the droplets included in the heat exchanged cooling air are mostly separated, the droplets are not discharged through the exhaust hose 83. In addition, the present invention can prevent the discharge of water droplets directly to the exhaust hose (83) because it is a method of pushing out the exhaust air rather than inhaling and exhausting the exhaust air. Therefore, the present invention does not need to install a shatterproof plate for preventing the water droplets from scattering.

On the other hand, the mobile water-cooled air conditioner 1 according to the present invention is limited to the cooling air for cooling the refrigerant flows through the upper space (A) of the housing. That is, the air inlet is not formed in the lower space B and is substantially sealed. Therefore, the noise emitted from the compressor 71 and the blower fan 73 installed in the lower space B does not leak to the outside. In addition, the noise generated in the blower fan 73 is introduced into the condenser case 60 together with the cooling air. At this time, the condenser case 60 is substantially sealed and has a relatively enlarged area, so that the noise generated in the blower fan 73 is eliminated. As such, the present invention can minimize the generation of noise because the condenser case 60 serves as a silencer.

In addition, the mobile water-cooled air conditioner 1 according to the present invention is provided with an air induction passage 42 of a predetermined shape around the air induction tool 41 of the horizontal plate 40 into which the cooling air flows. A sound absorbing plate 57 is installed on the inner side of the vertical blocking wall 56 of 42 to minimize the noise generated in the lower space B from being transmitted to the upper space A.

As described above, the mobile water-cooled heat exchanger according to the present invention minimizes the amount of cooling air discharged to the outside through the exhaust hose, thereby increasing cooling efficiency and energy efficiency and minimizing noise generation.

In addition, the present invention is installed in a blower fan for blowing the cooling air horizontally with the condensation heat exchanger, so that the flow of the cooling air and the cooling water perpendicular to each other to prevent the cooling water from being heated by the heated cooling air, the cooling air and In addition to preventing an increase in the amount of cooling water used, the scattering plate is omitted to minimize the flow resistance of the exhaust air, thereby improving energy efficiency and minimizing noise.

The present invention also partitions the housing into an upper space and a lower space through a horizontal plate, and simultaneously installs a heat exchanger and a blower fan of the condenser in a sealed condenser case, and provides a cooling air inlet in a lower space where a water-cooled condenser is installed. Since it does not form, there is an effect that the noise generated in the blower and the compressor is not radiated to the room.

In addition, the present invention has an effect that the noise generated in the blower fan is absorbed in the inner space of the condenser case in which the heat exchanger for the condenser is installed by forming an air passage having a reduced diameter between the heat exchanger and the blower fan for the condenser.
