Description

Copper pipe gas leak control system {Piping Gas Leak Control System}

The present invention relates to a copper pipe gas leakage control system, and more particularly, it is formed in a hexahedral shape in which a plurality of detachable holes are formed on the side so that the joint of the copper pipe connecting the indoor unit and the outdoor unit of an air conditioner or constant temperature and humidifier is inserted and stored. The upper structure and the lower structure are hinged to make it possible to open and close, and the lower surface of the lower structure is formed to protrude so that the width becomes narrower toward the lower part. When the installed refrigerant is detected, the refrigerant signal is transmitted from the controller through the cable and a signal or alarm is provided to the terminal or PC. It relates to a gas leak control system.

In general, an air conditioner and a constant temperature and humidity constant (hereinafter referred to as an 'air conditioner') are devices that cool or heat an indoor space by performing a process of compressing, condensing, expanding and evaporating a refrigerant, and an outdoor unit and the outdoor unit It consists of an indoor unit connected to the

In addition, the air conditioner is divided into a cooling system to supply only cold air to the room by operating the refrigerant cycle in only one direction, and a cooling system for selectively operating the refrigerant cycle in both directions to supply cold air or heat to the room.

In addition, the air conditioner basically forms a refrigeration cycle consisting of a compressor, a condenser, an expansion valve, and an evaporator. The gas refrigerant compressed in the compressor flows into the condenser to undergo a phase change into the liquid refrigerant. As the refrigerant undergoes a phase change in the condenser, heat is emitted to the outside. Thereafter, the refrigerant discharged from the condenser expands through the expansion valve and flows into the evaporator. The liquid refrigerant flowing into the evaporator undergoes a phase change into gaseous refrigerant. Similarly, the refrigerant absorbs external heat while undergoing a phase change in the evaporator.

In addition, the air conditioner is divided into a general air conditioner in which one indoor unit is connected to an outdoor unit and a multi air conditioner in which a plurality of indoor units are connected to an outdoor unit. In such a multi-air conditioner, a plurality of refrigerant pipes connected to the indoor unit should be installed.

When the indoor unit and outdoor unit are installed at different installation locations, the copper pipe decides to pass through the wall in the process of connecting them, installs close to fixed equipment, and sometimes passes through inter-floor concrete.

In particular, the seams of copper pipes are usually welded, and in places where it is difficult to insert welding rods, such as inside walls, super-accessible areas for fixed equipment, and inside inter-story concrete, sufficient welding cannot be achieved. may be leaked.

Such refrigerant leakage has a problem in that the desired air conditioning, constant temperature or constant humidity functions are deteriorated due to a lack of refrigerant, and a new refrigerant must be introduced. .

Various techniques have been developed to find the location of the refrigerant leak.

Patent Laid-Open No. 10-2009-0044785 (refrigerant leak detection system and control method thereof) is provided with a refrigerant detection device between the air conditioner and the ventilation device to detect the refrigerant leakage by detecting the refrigerant gas leakage concentration when the refrigerant leaks. is a technique to However, the above patent can be applied when there is a very large amount of leaking refrigerant, but in the case of a fine leaking refrigerant, it cannot be detected at all. Normally, the leaking refrigerant leaks very little because it leaks past the weld, and when a large amount is leaked at once, it is already in a state that cannot be used, so the above technique cannot be used realistically.

Next, there is Korean Patent Laid-Open No. 10-2014-0100341 (a device for detecting a location of a refrigerant leak in an air conditioner and a method for detecting a location of a refrigerant leak in an air conditioner). The above patent is a technology for detecting a refrigerant leak position by having a sensor installed in a refrigerant pipe to detect an acoustic wave, arranging the measured values in order of magnitude, and selecting the highest ranked detection value. However, the above technology is not only very complicated, but also has a problem in that it is difficult to apply when the copper pipe is combined with other structures of the building.

Therefore, there is a need for a new refrigerant leak detection system capable of easily detecting a simple yet minute refrigerant leak and notifying the location thereof.

Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings so that those of ordinary skill in the art can easily implement them.

The present invention is a copper pipe gas leak control system that can easily detect a refrigerant leaking little by little from the copper pipe 10 connecting the indoor unit 1 and the outdoor unit 2 of the air conditioner and check the location of the refrigerant leak. As shown in Figures 1 to 4,

A hollow cylindrical or hexahedron having a plurality of detachable holes 111 formed on the side surface so that the joint 11 of the copper pipe 10 made of a refrigerant pipe connecting the indoor unit 1 and the outdoor unit 2 of the air conditioner is inserted. The sensor is formed in a shape, and the upper structure 110a and the lower structure 110b are hinged to open and close, and the lower surface of the lower structure 110b protrudes into a narrow area to collect the refrigerant heavier than air. box 110 and

A cable 130 through which the detection signal of the refrigerant detection sensor 120 passes and supplies power to the refrigerant detection sensor 120;

and a controller 140 that receives a refrigerant leak signal from the cable 130 and provides it to a terminal in charge or a manager.

The air conditioner of the present invention is a concept including a thermo-hygrostat.

The air conditioner generally uses a copper pipe 10 with good durability as a refrigerant pipe connecting the indoor unit 1 and the outdoor unit 2, and the copper pipe 10 has a plurality of joints 11 connecting to each other. do.

As shown in FIG. 1, the seam 11 may be provided in about 4 to 10 locations in the copper pipe 10 with a length of 30 to 60 m connecting the indoor unit 1 and the outdoor unit 2, and the copper pipe ( 10) takes L-shaped, U-shaped, T-shaped, and ⊥-shaped forms that are welded or bent. In this case, when the seam 11 is located close to the floor or fixed equipment, it is difficult to weld and it is sometimes difficult to check whether the joint is connected with the naked eye.

When the copper pipe 10 is formed in an L-shape, the joint 11 is provided in three places, in the case of the U-shape, it is provided in two places, and in the case of the T-shape, it is provided in four places. . These seams 11 are usually welded to combine different copper pipes, and may be installed in places where access is difficult, such as inside a wall, in the vicinity of a fixed facility, or between floors. In the air conditioner, leakage of the refrigerant hardly occurs anywhere other than these joints.

Since the high-pressure refrigerant moves inside the copper pipe 10 , when a fine gap is generated in the joint 11 , the refrigerant is gradually discharged through the gap due to the high pressure, and the gap gradually increases. When the high-pressure refrigerant comes out of the copper pipe 11, it diffuses or disperses into the air because it is a low pressure of atmospheric pressure.

Accordingly, the present invention installs a hollow sensor box 110 blocked on all sides at the seam 11, collects refrigerant in the sensor box 110, and allows a lot of refrigerant in a narrow space to be used as a refrigerant detection sensor 120. It makes it easy to detect whether the refrigerant is leaking, and when the refrigerant is detected, it is configured to notify the user through the controller 140 connected to the cable 130 .

The sensor box 110 has a hollow cylindrical or hexahedral shape, and an upper structure 110a and a lower structure 110b corresponding to the upper and lower parts are hinged to open and close, and the upper structure 110a) At a point where the lower structure 110b and the lower structure 110b meet, a plurality of detachable holes 111 into which the copper pipe 10 is inserted is formed.

After the sensor box 110 opens and opens the upper structure 110a around the hinge, removes the cover plate 114 blocking the detachable hole 111, and then inserts the copper pipe 10 into the detachable hole 111. . Thereafter, the upper structure 110a and the lower structure 110b are coupled to each other by the opening/closing means 112 . A copper pipe 10 is inserted into the sensor box 110 , the refrigerant detection sensor 120 is disposed at the lowest end 115 , and the cable 130 connected to the refrigerant detection sensor 120 is connected to the detachable hole 111 . ) and extends to the outside. The sensor box 110 may be fixed around the inner copper pipe 10 so as not to rotate around it or fixed with a separate fixture.

The joint 11 of the copper pipe 10 is located inside the sensor box 110, and the inner lower surface of the sensor box 110 is formed to protrude with a narrower width, so that the refrigerant leaking from the joint 11 moves downward. provided to gather. The lowermost end 115 that descends to the bottom inside the lower structure 110b may be the center, but may be disposed to be biased toward either side. In the case of a T-joint, a copper pipe connected to the central portion may be disposed, and in this case, it is biased toward either side to form the lowermost end 115 . The lowermost end 115 may be formed to have a narrow and long portion protruding downward like a cup, or may be formed to gradually narrow as shown in FIG. 2(b) . However, the horizontal area inside the lower structure is narrowed to form a structure that can collect the leaked refrigerant so that the refrigerant detection sensor 112 can easily detect the refrigerant.

A refrigerant detecting sensor 120 is mounted on the inner lower surface of the sensor box 110 to detect the refrigerant collected in the lower portion, and the refrigerant detecting sensor 120 is connected to the controller 140 by wire through the cable 130 and It is connected to transmit a detection signal and receive power. The refrigerant sensor 120 is preferably provided at the lowermost end 115 of the lower structure 110b. When protruding long in a narrow area, it may be arranged to rise slightly from the lowermost end 115 .

Each refrigerant detection sensor 120 is given a different ID, and is stored in the memory inside the controller 140 at which position is coupled to the copper pipe according to the ID. When the refrigerant detection sensor 120 detects the refrigerant and transmits a signal to the controller 140 via the cable 130, it also transmits its ID to know the position of the joint 11 leaked from the controller.

The detachable hole 111 is used by opening only a necessary part according to the shape of the copper pipe 10 from four sides at intervals of 90 degrees. These detachable holes 111 are coupled with the connecting rod (not shown) in two or more places and are closed by being coupled to the cover plate 114 that blocks the detachable hole, and the cover plate 114 is removed by cutting the connecting rod by pressurization. Remove and insert the opened detachable hole 111 into the copper pipe (10). The cover plate 114 may be coupled to any one of the upper structure 110a and the lower structure 110b. If the cover plate 114 is coupled to the lower structure 111b, the detachable hole 111 of the upper structure 110a is drilled when the upper structure 110a is opened and the detachable hole 111 of the lower structure 110b is opened. 111) has a round cover plate 114 protrudes upward. When the cover plate is coupled to the upper structure (110a), the opposite is the case.

The cover plate 114 is coupled to the upper structure 110a or the lower structure 110b, and the connecting rod is cut by pressing the cover plate 114 in the detachable hole 111 corresponding to the position where the copper pipe 10 is inserted. to remove In the detachable hole 111 from which the cover plate 114 is not removed, there is still the sensor box 110 in a closed state in which the cover plate is coupled. The attachment of the cover plate 114 reduces leakage of the leaked refrigerant to the outside of the sensor box.

In the sensor box 110 coupled to the copper pipe 10 having the T-shaped joint 11 , a detachable hole 111 may be further installed at the upper or lower portion. The detachable hole 111 installed at this time should not overlap with the lowermost end 115 . In addition, all the detachable holes 111 are formed at a predetermined height at the lowermost end 115 to prevent the collected refrigerant from escaping through the detachable hole.

As shown in FIG. 3 , the cable 130 is connected to the refrigerant detection sensor 120 inside the sensor box 110 and is formed to extend outside the sensor box 110 , together with the copper pipe 10 . Penetrating through the detachable hole 111, the copper pipe 10 and the cable 130 between the sensor box 110 and the sensor box 110 is finished in a state in which the insulation material 150 is wrapped at the same time.

As shown in FIG. 3 , the cable 130 inside the sensor box 110 is spaced apart from the copper pipe 10 , and is in contact with the copper pipe 10 between the sensor box 110 and the sensor box 110 . This is because the refrigerant detection sensor 120 connected to the cable 130 must be installed at the lower end of the lower structure 110b. The cable 130 is connected from one sensor box 110 to another sensor box 110 and is coupled to the refrigerant detection sensor 120 . Between the sensor boxes 110 , the cable 130 is in contact with the copper pipe 10 , because it is provided in the insulating material 150 that simultaneously surrounds the outer circumferential surface of the copper pipe 10 and the cable 130 .

The insulating material 150 surrounds the exterior of the copper pipe 10 without the sensor box 110 , and the sensor box 110 surrounds the exterior of the sensor box 110 in a state separated from the copper pipe 10 . The inside of the sensor box 110 is hollow, and there should be no element impeding the movement of the refrigerant between the refrigerant detection sensor 120 in the copper pipe 10 . That is, the refrigerant leaked from the copper pipe 10 must be able to move to the lowermost end 115 without being hindered in movement. covers the exterior of

The sensor box 110 receives and collects refrigerant from the lower structure 110b and is formed to remain closed until an operator opens it, so that the refrigerant cannot escape to the outside.

As such, in the sensor box 110, the upper structure 110a and the lower structure 110b are hinged, and the opening/closing means 112 is formed between the upper structure 110a and the lower structure 110b, so that it can be easily opened and closed. It remains closed until the operator opens it.

The refrigerant detection sensor 120 installed on the inner lower surface of the sensor box 110 lower structure 110b is connected to the cable 130 to transmit the refrigerant detection signal to the controller 140 by wire, and the cable ( 130) is connected to the controller 140, receives the refrigerant signal from the controller 140, provides a signal or an alarm to the manager or the person in charge terminal.

The refrigerant detection sensor 120 has an ID (ID) that indicates each location, so that the location of the refrigerant leakage can be easily found, and the controller 140 that delivers power to the refrigerant detection sensor 120 is through the panel screen. You can easily check the location of the refrigerant leak.

In addition, the controller 140 is connected to the mobile communication terminal wirelessly and to the PC by wire, and transmits the position of the refrigerant detection sensor 120 in which the refrigerant is detected as a detection signal.

Such a copper pipe gas leak control system can accurately detect the leak position of the refrigerant by the refrigerant detection signal sent from the controller 140, and allows maintenance such as confirmation and replacement to be performed.

Accordingly, in the copper pipe gas leakage control system of the present invention, the joint 11 of the copper pipe 10 connecting the indoor unit 1 and the outdoor unit 2 of the air conditioner is inserted and stored in the four sides with detachable holes 111. The formed hexahedron shape is formed so that the upper structure 110a and the lower structure 110b are hinged to be able to open and close, and the lower surface of the lower structure 110b is formed to protrude so that the width becomes narrower as it goes to the bottom. When the refrigerant detection sensor 120 is mounted on the lower inner side of the sensor box 110 provided to collect the refrigerant to detect whether the refrigerant is leaking, the refrigerant signal is transmitted from the controller 140 through the cable 130 to the terminal or pc By providing a low signal or alarm, there is an effect that can easily detect and maintain the refrigerant gas leak position.

In addition, according to the present invention, the copper pipe 10 in which the joint 11 is formed in various forms can be inserted by applying force to open the detachable hole 111 when used in a closed state, and the sensor box 110 outside It has the effect of maintaining the seal to prevent the refrigerant from escaping.

The present invention has an advantage in that the leaked refrigerant can be quickly detected because the leaked refrigerant is collected and detected even when the refrigerant leaks very little.
