Description

  The present invention relates to an auxiliary cooling device that cools intake air of a condenser when the temperature is high in a condenser used in an air conditioning / freezing / refrigeration apparatus or the like.

  Conventionally, a condenser used in a refrigeration cycle such as an air conditioner / refrigerator / refrigerator has a high temperature due to heat generated when the refrigerant is liquefied, and thus needs to be cooled. The air-cooling method in which the condenser is cooled with air is inexpensive because it has a simple apparatus structure, but there is a problem that the cooling efficiency in the interior and the room is lowered at high temperatures in summer. Therefore, many proposals have been made to use an auxiliary cooling device for an air-cooled condenser, and a typical example of such an auxiliary cooling device is known in which water is directly sprayed on a heat radiation fin to improve cooling efficiency.

  Sprinkling type auxiliary cooling device is one or more spray nozzles that spray fine granular or mist water almost uniformly on the heat radiation fins of the condenser of the air conditioner outdoor unit, and the control for operating and stopping the nozzles For example, when the outside air temperature reaches a high temperature of about 35 ° C. when the compressor is in operation, excessive drain water does not come out from each spray nozzle portion with respect to the heat-radiating fin that has been heated. The amount of water is adjusted and water is sprayed, and the heat dissipating fins provided in the refrigerant pipe are cooled by the latent heat of evaporation of the sprayed water. This type of auxiliary cooling device is operated as a conventional air cooling device at times other than summer, and scales and scales adhere to the surface of the radiating fins while the operation is continued for a long period of time. Reduction in exchange efficiency and corrosion of heat radiating fins occur.

  As an example of an auxiliary cooling device used for an air-cooled condenser, the present applicant has already arranged a cooling mat in the vicinity of the heat dissipating fins of the condenser, and caused cooling water to flow down to the cooling mat so that the intake air of the condenser is reduced. A method of cooling is proposed (see Patent Document 1). In this type of auxiliary cooling device, the cooling water is not blown directly onto the radiator fins of the condenser, but the condenser is indirectly cooled by the cooling water using the cooling water to cool the radiator fins. Corrosion and scale adhesion due to cooling water of the fins can be reduced. In addition, since this auxiliary cooling device can be added to a conventional condenser, it can be attached to an existing unit, and can be easily attached and detached. Moreover, since the cooling mat can also utilize a waste material, it has the advantage that it also becomes effective use of resources.

  FIG. 5 is a diagram showing an example of an auxiliary cooling device fixed to an outdoor unit by a conventional fixing means, and FIG. 6 is a schematic diagram showing an example of a conventional refrigeration cycle. In the refrigeration cycle, the compressor 11, the condenser 2, the dryer 14, the expansion valve 13, and the evaporator 12 are connected by a refrigerant pipe 7 so as to constitute the refrigeration cycle 10. An auxiliary cooling device 20 is provided in the vicinity of a condenser constituting a conventionally known refrigeration cycle (not shown), that is, at a position away from the cooling fan 3 attached to the condenser 2 by a certain distance. The auxiliary cooling device 20 includes a mat-like cooling mat 21, a water storage tank 25 that stores cooling water, and a water supply unit 30 that supplies cooling water to a water supply pipe 31. As shown in FIG. 5, the auxiliary cooling device 20 includes, on the upper side, a water sprinkler 22 that causes the cooling water supplied from the water supply unit 30 to flow down to the cooling mat 21, and a drainage trough 23 that collects the water flowing down the cooling mat 21. I have. The water supply device 30 includes, for example, a water supply pipe 31 that communicates with the water pipe, an electromagnetic valve 32 that is interposed in the water supply pipe 31 and serves as an on-off valve for shutting off or passing the tap water, and a thermostat that controls opening and closing of the electromagnetic valve 32 33, and a sensor 34 for measuring the temperature of the air flowing into the auxiliary cooling device 20 in order to operate the thermostat 33.

  The cooling mat 21 is installed in order to prevent the cooling water from splashing as it falls and flowing along with the air sucked by the cooling fan 3, and as a property of the material of the cooling mat 21 It is preferable that the air resistance is low when it passes through the air and heat exchange with the falling cooling water is smooth and durable. As the mat through which air easily passes, it is preferable to use, for example, a non-woven fibrous body, for example, a material obtained by recycling waste plastic into a fibrous form from the viewpoint of effective use of resources. The shape of the cooling mat 21 is preferably a shape that substantially covers the air suction surface of the condenser 2, and the thickness may be about several centimeters depending on the material and shape. In addition, the cooling mat 21 can be easily installed by selecting a stretchable material. And this cooling mat 21 is attached to the condenser 2 by the support part 27 (refer FIG. 5).

  The cooling water cools down the air passing toward the condenser 2 while flowing down the cooling mat 21 in a comb shape from the water sprinkler 22. The cooling water that has cooled the air sucked into the condenser 2 is collected in the drainage basin 23. The water sprinkler 22 sprays the cooling water supplied from the water supply pipe 31 of the water supply device 30 evenly on the upper portion of the cooling mat 21, and a plurality of water sprinkling holes are drilled at the bottom thereof. The cooling water is formed to drop substantially uniformly from the holes. The drainage basin 23 is a basin for receiving cooling water dripping from the lower portion of the cooling mat 21.

  With this configuration, when the sensor 34 senses that the temperature of the inflowing air is equal to or higher than a set value, the thermostat 33 operates to open and close the electromagnetic valve 32. When the solenoid valve 32 is opened, tap water is supplied from the water supply pipe 31 to the cooling mat 21 through a watering nozzle (not shown). Moreover, as a drainage means, it drains to the water storage tank 25 through the drain pipe 28 (refer FIG. 5) connected to the one end part of the drainage basin 23, or drains directly to the ground. The cooling water circulates while cooling the air flowing into the condenser 2 in this way.

  The refrigeration cycle 10 has been described with one condenser 2 arranged, but as shown in FIG. 5, the two condensers 2 and 2a are arranged mirror-symmetrically, and the auxiliary cooling devices 20 and 20a are respectively arranged. It can also be made symmetrical by providing it on the air inflow side of the condensers 2 and 2a. Moreover, the combination of the condenser 2 and the auxiliary cooling device 20 may be one set, and a plurality of sets may be arranged in parallel. Moreover, in the above embodiment, although the water sprinkler 22 as a watering means was arrange | positioned above the cooling mat 21, the whole structure can be simplified by arrange | positioning a watering pipe in the cooling mat 21. FIG. . Furthermore, as long as the cooling mat 21 is a material in which cooling water is transferred to the outside of the fibrous material, the cooling mat 21 may employ other forms such as a synthetic resin body having open cells.

  As the cooling water, drain water generated in the evaporator 12 may be used instead of tap water. That is, drain water is supplied from the drain pan to the water storage tank by a pump. The cooling water in the water storage tank 25 is supplied again to the water supply pipe 31 by the water supply device 30 through the circulation water distribution pipe by the pump, and after flowing into the water storage tank 25 through the water sprinkler 22 after being used for cooling. The water sprinkler 22 and the drain spit 23 may be a sprinkler pipe and a drain pipe, respectively. Hygiene / environmental improvement can be achieved by putting Legionella sanitizer in the water tank 25. The sterilizing agent can be maintained in a favorable environmental condition by exchanging about once a month. The water temperature of the water storage tank 25 is constantly monitored by a sensor (not shown), and when the temperature becomes equal to or higher than the set temperature, the cooling water in the water storage tank 25 is drained, and at the same time, for example, tap water is newly supplied to the water storage tank 25. You may do it. Further, the cooling water in the water storage tank 25 may be forcibly drained once / day in order to maintain the environmental condition.

  In this way, in an indirect auxiliary cooling device using a cooling mat, the cooling mat is arranged at a certain distance from the radiation fins, so that the influence of cooling water on the radiation fins (corrosion, scale adhesion, etc.) is reduced. It is possible to reliably shut off, and a water spraying means is provided at the upper part of the cooling mat, a drainage means is provided at the lower part of the cooling mat, and a circulation for circulating the cooling water between the water draining means and the watering means. By providing the service pipe, it is possible to smoothly supply and drain the cooling mat and to effectively use the cooling water.

  However, an outdoor unit such as an air conditioner is installed outside the building and is in an environment where it is exposed to strong winds of buildings and rain and snow, so it is required to be firmly fixed. Since this type of indirect auxiliary cooling device is often installed with a view to installation possibilities in the field, in order to meet these requirements, a fixed unit drilled in the field to a painted unit is required. It is fixed by a nut through a bolt in the hole. The drilled bolt hole may rust from the painted unit surface, which may impair the appearance.

In addition, in an indirect auxiliary cooling device using a cooling mat, a space of a certain distance of about 20 mm is provided between the outdoor unit refrigerator and the outdoor cooling device when securing the auxiliary cooling device, in order to secure the air volume when the mat is clogged. In order to make such a gap, a cooling mat is attached to the outdoor unit refrigerator through a spacer having a thickness corresponding to the gap. Since the existing screw holes are used, it is necessary to individually manufacture spacers, which is a cause of hindering improvement in workability.
JP 2004-3806 (paragraphs [0014] to [0023], FIGS. 1 to 3)

  Therefore, when fixing the auxiliary cooling device to the outdoor unit, there is a problem to be solved in terms of obtaining an auxiliary cooling device that does not need to perform fixing processing such that a hole through which a bolt is inserted can be formed in the outdoor unit.

  It is an object of the present invention to prevent general appearance of spacers without impairing the appearance such that rust is generated due to the subsequent formation of a fixing hole when fixing the auxiliary cooling device to the outdoor unit. It is possible to provide an auxiliary cooling device that can reduce the cost.

In order to solve the above problem, the auxiliary cooling device mounting structure according to the present invention is disposed opposite to the heat dissipating part provided in the outdoor unit of the heat exchanging device and passes through the inside where water flows down to dissipate the heat dissipating part. In the auxiliary cooling device that cools the air sucked into the outside, a support rod member that is arranged corresponding to the corner portion of the outdoor unit and supports the weight of the auxiliary cooling device, and is locked to the auxiliary cooling device at both ends. A belt-shaped fixing member having a locking member and a spring member extending in the longitudinal direction at an intermediate portion is provided, and the auxiliary cooling device is supported by the support rod member by winding the fixing member around the outdoor unit. It consists is secured against the side face of the outdoor unit by the urging force of the member.

According to the auxiliary cooling device of the present invention, the belt-shaped fixing member is wound around the outdoor unit in a state where both ends of the fixing member are locked to the auxiliary cooling device, so that the spring member arranged at the intermediate portion in the longitudinal direction is wound. The auxiliary cooling device is pressed against and fixed to the side surface of the outdoor unit by the urging force. That is, the fixed member is disposed in a state of surrounding the chamber outboard motor Tei Runode, auxiliary cooling device is secured pressed against the side face of the outdoor unit with a belt-shaped fixing member which is tensioned by the contractile force of the spring member. Since the auxiliary cooling device is supported by the support bar member arranged corresponding to the corner portion of the outdoor unit, it is only necessary that the burden of supporting the auxiliary cooling device is eliminated by the worker during the mounting operation of the auxiliary cooling device. No unnecessary load is applied to the outdoor unit even when installed. Since there is no need for fixing the outdoor unit such as drilling, rust does not occur. Since the urging force of the spring member can be set to a size that can be opposed to various forces expected to act on the auxiliary cooling device, the auxiliary cooling device cannot be detached from the outdoor unit in the use state under the assumed environment. Absent.

  In this auxiliary cooling device, it is preferable that the fixing member has a limiter member that is arranged in parallel with the spring member and prevents the spring member from extending beyond its allowable extension length. If the spring member extends beyond the limit, composition deformation or cutting occurs, and the auxiliary cooling device is separated from the outdoor unit, resulting in a dangerous situation. Therefore, by arranging the limiter member in parallel with the spring member, even if the spring member undergoes compositional deformation or cutting, the limiter member replaces the spring member to avoid the failure of the fixing member. In this case, the spring member is preferably a coil spring, and the limiter member is preferably a wire disposed inside the spring member and having a length equal to the allowable extension length of the spring member. If the spring member is a coil spring and the wire is arranged through the air core portion of the coil spring, it can be compactly compact in terms of layout.

  In the above auxiliary cooling device, the length of the band can be changed by constituting both ends with locking metal fittings and connecting at least one of the locking metal fittings and the intermediate part with a band with a buckle. It is preferable that both ends of the fixing member are securely locked to the auxiliary cooling device by the locking metal fitting. Moreover, since the size of the outdoor unit varies depending on the heat exchange capacity and various types, the length of the fixing member wound around the outdoor unit also varies. Therefore, the auxiliary cooling device can be fixed in accordance with the size of the outdoor unit by changing the length of the band by connecting at least one of the locking fittings and the intermediate portion with a band with a buckle. .

In the auxiliary cooling device, the auxiliary cooling device, Rukoto Soo adjustably supported in the height direction position by supporting Jibo member is preferred. Since the position where the heat radiating unit is provided in the outdoor unit varies depending on the heat exchange capacity and various types, the height of the auxiliary cooling device to be attached to the outdoor unit also varies. Therefore, the auxiliary cooling equipment, by adjustably supporting the mounting position in the height direction by the support bar member, to adjust the height direction of the attachment position of the auxiliary cooling device in accordance with the format of the outdoor unit . Thereby, after adjusting a position according to the thermal radiation part of an outdoor unit, an auxiliary cooling device can be fixed to an outdoor unit.

  In the above auxiliary cooling device, the auxiliary cooling device can be fixed to the outdoor unit in a state where the square pipe is sandwiched between the outdoor unit as a spacer. When the auxiliary cooling device is clogged, it is preferable to secure a gap that allows the inflow of air between the auxiliary cooling device and the outdoor unit in order to ensure an air flow to the heat radiating section. The gap is secured by sandwiching the square pipe as a spacer between the auxiliary cooling device and the outdoor unit. As the spacer, a square pipe having an appropriate size may be selected from existing square pipes, and workability at the installation site of the auxiliary cooling device can be improved.

  In the above auxiliary cooling device, another auxiliary cooling device may be provided for the same outdoor unit depending on the capability of the heat exchange device. Another auxiliary cooling device can also be used as a fixing member by pressing against the outdoor unit together with the auxiliary cooling device based on the biasing force of the spring member.

  In the auxiliary cooling device provided with another auxiliary cooling device, the auxiliary cooling device and the other auxiliary cooling device can be arranged on opposite sides of the outdoor unit with the heat radiating part interposed therebetween.

Since the auxiliary cooling device mounting structure according to the present invention is configured as described above, the fixing member is wound around the outdoor unit in a state where both ends of the fixing member are locked to the auxiliary cooling device. The auxiliary cooling device is pressed against and fixed to the side surface of the outdoor unit by the biasing force of the spring member disposed in the intermediate portion. Therefore, since the fixing hole cannot be drilled later, the appearance is not impaired such as rust generated due to such drilling. Further, since a general-purpose spacer such as a square pipe can be used, an auxiliary cooling device that can improve the workability at the construction site and reduce the cost can be obtained. In addition, in this auxiliary cooling device mounting structure, the weight of the auxiliary cooling device is supported by the support rod member arranged corresponding to the corner portion of the outdoor unit, and of course during the mounting operation, even in the mounted state. The weight of the auxiliary cooling device is supported by the support bar member. Therefore, the operator does not need to support the weight of the auxiliary cooling device in the mounting operation of the auxiliary cooling device to the outdoor unit, and the workability of the mounting operation can be greatly improved. No unnecessary load is applied to the

Hereinafter, with reference to the accompanying drawings, to explain the embodiment of the mounting structure of the auxiliary cooling device according to the present invention. FIG. 1 is a perspective view showing an example of an outdoor unit of a heat exchange device to which an auxiliary cooling device mounting structure according to the present invention is applied. 2 is a schematic top view of the outdoor unit shown in FIG. 1, FIG. 3 is an enlarged cross-sectional view of a part of FIG. 2, and FIG. 4 is an enlarged view of an intermediate part that is a part of the fixing member. It is a perspective view. In FIG. 1 to FIG. 3, components that are substantially the same as those shown in FIG.

In the auxiliary cooling device mounting structure is applied for the auxiliary cooling device shown in FIG. 1 and the outdoor unit, similar to the case shown in FIG. 5, two auxiliary cooling device 20,20a faces the opposite sides of the outdoor unit 1 It is applied to each side. Each side surface of the outdoor unit 1 is composed of a flat plate in which a suction window leading to a condenser is formed, and the auxiliary cooling devices 20 and 20a each have a frame provided with a frame frame that fixes the periphery of the cooling mat 21. It has a mat structure. When the amount of heat generated in the condenser 2 is large, such as when the capacity of the heat exchange device is high, in addition to the auxiliary cooling device 20 for the outdoor unit 1, another standard having the same structure as that of the auxiliary cooling device 20 is used. An auxiliary cooling device 20a is provided. Since the outdoor unit 1 is of a type in which the cooling fan 3 is provided on the ceiling and exhausts upward, the auxiliary cooling device 20a is provided on the side surface of the outdoor unit 1 opposite to the auxiliary cooling device 20, and the heat radiating unit is provided. Cooling air can be introduced from both sides sandwiched.

  The weights of the auxiliary cooling devices 20 and 20a are preferably supported directly on the floor surface rather than supported by the outdoor unit 1 from the viewpoint of load support and safety. Therefore, the auxiliary cooling devices 20 and 20a are supported by an angle member 40 that is a support bar member for the weight of each device. The angle member 40 can be, for example, an L-shaped member sold as a part of assembly furniture. The angle member 40 is disposed so as to be applied to the corner portions of the auxiliary cooling devices 20 and 20a. The auxiliary cooling devices 20 and 20a can be bolted to each angle member 40 by tightening the wing nut 42 through a plurality of long holes 41 formed in advance in the longitudinal direction in the angle member 40. Since the position where the heat radiating portion is provided in the outdoor unit 1 varies depending on the heat exchange capacity and various types, the mounting height of the auxiliary cooling devices 20 and 20a varies depending on the type of the outdoor unit 1. Therefore, by changing the tightening position of the long hole 41 by the wing nut 42, the mounting position in the height direction of the auxiliary cooling devices 20 and 20a on the angle member 40 can be adjusted. Thereby, the preparation for fixing the auxiliary cooling devices 20 and 20a to the outdoor unit 1 after adjusting the position according to the heat radiating part of the outdoor unit 1 is completed. At the lower end portion of each angle member 40, a foot portion 43 is provided that can finely adjust the height relative to the floor surface or the like with a screw.

  The fixing member 45 that fixes the auxiliary cooling devices 20 and 20a to the outdoor unit 1 has a form of a binding tool including a band 47 with a spring member to be described later interposed in an intermediate portion 46. Both end portions of the fixing member 45 are constituted by locking metal fittings 48 and 49. As best shown in FIG. 2, the fixing member 45 locks the auxiliary metal cooling devices 20 at the both ends of the band 47 wound around the outdoor unit 1 with the auxiliary cooling device 20. It is pressed against the side surface of the outdoor unit 1 and fixed by the urging force of the spring member disposed in the intermediate portion 46 in the longitudinal direction. The other auxiliary cooling device 20a is also fixed to the outdoor unit 1 by being pressed against the opposite side surface of the outdoor unit 1 by the urging force of the spring member by stretching the band 47 along the outside thereof. . As described above, the single fixing member 45 also serves to fix the auxiliary cooling devices 20 and 20a to the outdoor unit 1.

  When the auxiliary cooling devices 20, 20 a are fixed to the outdoor unit 1, the square pipe 50 is sandwiched between the auxiliary cooling devices 20, 20 a and the outdoor unit 1 as a spacer. The spacer secures an air flow between the auxiliary cooling devices 20 and 20a and the outdoor unit 1 and allows air flow to the heat radiating portion even when the auxiliary cooling devices 20 and 20a are clogged. To be provided. The number and arrangement of the square pipes 50 are preferably arranged at least at four corners in order to obtain a stable fixed state. As the spacer, a square pipe having an appropriate size may be selected according to the size of the gap to be set, and workability at the installation site of the auxiliary cooling devices 20 and 20a can be improved. . The cooling water from the drainage basin 23 of the auxiliary cooling devices 20 and 20a is drained through the drainage pipe 29 from the side of the auxiliary cooling devices 20 and 20a.

  Details of the intermediate portion 46 of the fixing member 45 will be described with reference to FIGS. 3 and 4. The intermediate portion 46 includes a coil spring 51 as a spring member and a wire 53 as a limiter member arranged in parallel with the coil spring 51. Like the both end portions 51a and 51b of the coil spring 51, the wire 53 is locked in the locking hole 48a formed in the locking bracket 48 and the locking hole 52a of the buckle 52, and then formed into a ring shape by caulking or the like. Has been. In the fixing member 45, the coil spring 51 is used in a constant extension state in order to obtain a force for pressing the auxiliary cooling devices 20 and 20a against the outdoor unit 1. If the spring member such as the coil spring 51 is stretched beyond the limit, the composition is likely to be deformed or cut. If this happens, the auxiliary cooling devices 20 and 20a may be separated from the outdoor unit 1 and blown by the wind. Fall into a situation. Therefore, the limiter member is arranged in parallel with the coil spring 51. The limiter member is a wire 53 that is disposed inside the coil spring 51 and has a length equal to the allowable extension length of the coil spring 51. When the coil spring 51 tries to extend beyond its permissible extension length, when the composition deformation or cutting occurs, the wire 53 replaces the coil spring 51 and the length of the fixing member 45 exceeds the limit. It is possible to prevent the auxiliary cooling devices 20 and 20a from being detached from the outdoor unit 1. If the wire 53 is disposed through the air core portion of the coil spring 51, the fixing member 45 can be gathered in a compact and compact manner in terms of layout.

  Both ends of the fixing member 45 are constituted by locking metal fittings 48 and 49, and one locking metal fitting 49 and the intermediate portion 46 are connected by a band 47 with a buckle 52. The fixing member 45 is reliably locked by being locked to a structural portion such as a frame frame of the auxiliary cooling devices 20 and 20a by the locking metal fittings 48 and 49. In the buckle 52, the band 47 is fixed by friction gripping which operates the band 47 by a cam type, but the length of the band 47 can be changed by adjusting the gripping position of the band 47 in the buckle 52. . Since the size of the outdoor unit 1 varies depending on the heat exchange capacity and various types, the length of the fixing member necessary to surround the outdoor unit 1 also varies. By connecting at least one of the metal fittings 48, 49 and the intermediate portion 46 with a band 47 with a buckle 52, the length of the band 47 is changed to make the auxiliary cooling devices 20, 20a correspond to the size of the outdoor unit 1. Can be fixed.

  In this embodiment, the fixing member 45 is wound around the outdoor unit 1 in a state where locking metal fittings 48 and 49 provided at both ends of the fixing member 45 are locked to the auxiliary cooling devices 20 and 20a. By setting the coil spring 51 disposed in the portion 46 in an extended state, the restoring force of the coil spring 51 is in a state of pressing the auxiliary cooling devices 20 and 20a against the outdoor unit 1, and the auxiliary cooling devices 20 and 20a are outdoors. It is fixed to the machine 1. Since the fixing member 45 is arranged in a state surrounding the outdoor unit 1, the auxiliary cooling devices 20 and 20 a are fixed with tension by the restoring force of the coil spring 51. Since there is no need for fixing the outdoor unit 1 such as drilling, rust does not occur. Since the restoring force of the coil spring 51 can be set to a size that can be opposed to various forces expected to act on the auxiliary cooling devices 20 and 20a, the auxiliary cooling devices 20 and 20a are used in an assumed environment. Does not come off the outdoor unit 1.
