  The present invention relates to a room unit of an air conditioner. More specifically, the present invention relates to an apparatus that promotes convection in an indoor atmosphere by a chimney effect to efficiently transfer heat, and further uses radiant heat to achieve uniform air conditioning in the room.

  For example, there are various types of air conditioners that perform indoor air conditioning. Of these, piping that circulates the heat medium is placed indoors as a heat exchange part, and heat is exchanged with the indoor atmosphere using heat radiation from the heat exchange part and air convection along the heat exchange part.

The heat pipe <1> and the heat storage body <2> are provided alternately in a state of being spaced apart from each other and exposed to the space portion. <1> and heat storage body <2> are arranged side by side in parallel in the longitudinal direction with the length direction oriented in the horizontal direction, and have high heat exchange characteristics by radiation and convection, which also contributes to energy saving effect It is excellent.

JP 2007-303727 A

  The conventional air conditioner is sufficiently useful as a device that effectively performs indoor air conditioning using heat radiation and convection. However, since this air conditioner is an open type in which a heating element is exposed, the efficiency of performing indoor air conditioning by radiating heat is excellent. For example, when heating is performed, the vicinity of the heating element is warm. However, if it leaves | separates from a heat generating body, the heating effect will fall easily, and there was room for improvement from a viewpoint which moves heat by the convection of room air and performs indoor air conditioning.

  By the way, the natural air cooling mechanism using the so-called chimney effect is already known (for example, see http://www.pref.okayama.jp/sangyo/kougi/publishment/report/pdf/2010/H23-13.pdf). . The inventor has paid attention to the use of the chimney effect in order to promote the movement of heat by air convection in the room.

  Therefore, when rectifying plates are arranged on both the front and back sides of the heating element of the conventional air conditioner installed upright, the convection of the indoor air is promoted by the chimney effect and the heat transfer is performed well, but this time the heating element Since the current is shielded by each rectifying plate, the efficiency of heat radiation from the heating element is deteriorated, and it is thus difficult to expect uniform air conditioning in the room.

  The term “exotherm” in the present specification and claims includes not only the meaning of generating heat but also the meaning of generating cold.

  The term “rectifier plate” in the present specification and claims is used as a term indicating a plate-like object that exhibits a chimney effect.

(Function)
The operation of the room unit of the air conditioner according to the present invention will be described.
First, when the room is heated by the room unit of the air conditioner, the air in the vicinity of the heating element is heated by radiant heat, and natural convection of air from the bottom to the top is generated along the heating element.

  As a result, external air flows from the lower gap of the room unit through the lower openings between the rectifying plates and is heated by the heating element while rising between the rectifying plates, thereby continuing the convection. Moreover, the flow rate of the convection air increases due to the chimney effect caused by arranging the rectifying plates on both the front and back sides of the heating element.

  The heated air rising between the current plates is discharged to the outside through the upper openings between the current plates from the gaps at the top of the room unit. The discharged air has an increased flow velocity due to the chimney effect, and reaches a position away from the room unit along the ceiling surface. In addition, the air cools and falls with this movement. In this way, the indoor air circulates throughout the room while being heated by the heating element.

  On the other hand, part of the radiant heat radiated from the heating element passes through each radiant heat transmission hole formed in each rectifying plate and is released into the room. The rate at which the radiant heat passes through the radiant heat transmission hole depends on the aperture ratio of the radiant heat transmission hole. Thereby, radiant heat is used directly and effectively to warm the temperature of indoor air.

  Also, of the radiant heat, the radiant heat that could not pass through each radiant heat transmission hole is reflected by the reflecting surface on the inner surface side of each rectifying plate, and further diffused between the heating element and the reflecting surfaces of other rectifying plates. Occur. As a result, part of the radiant heat is released into the room through each radiant heat transmission hole, and part is released into the room from the upper and lower openings between the current plates. Furthermore, a part of the radiant heat heats each rectifying plate to raise the temperature, and radiant heat from each rectifying plate to the outside is released into the room.

  As described above, according to the room unit of the air conditioner according to the present invention, while the reflection and release of the radiant heat are repeated, the room is well heated by the radiant heat together with the heat moving by the convection of the air, and the air conditioning of the entire room is performed. Can be done effectively.

  Also, when cooling indoors, unlike the case of heating, the air is cooled by the heating element, so the convection of the air along the heating element and each rectifying plate is from the top to the bottom and is cooled. The air flow is almost opposite to that in the case of heating.

Note that the heating element uses water, an antifreeze liquid, oil, a liquid such as a liquid phase refrigerant in a refrigeration circuit, or a gas such as a refrigerant gas as a heat medium.
The heat energy generated by the circulation of the heat medium includes radiant heat released through the radiant heat transmission holes of the rectifying plate, and radiant heat and convective heat released by heat generated on the surface of the rectifying plate by heat energy of the surface of the heating element. The air in the atmosphere is convected by the heat energy of the surface of the heating element, and air conditioning is performed by natural convection of the atmosphere and radiant heat.

  In addition, the natural convection generated by the heat energy from the heating element inside each rectifying plate, the atmosphere is preferably taken into the inside of each rectifying plate, and the convection through the space inside each rectifying plate is promoted. By having an effect of promoting heat transfer and heat exchange with the atmosphere, air conditioning of the indoor atmosphere can be performed satisfactorily.

  Furthermore, according to the present invention, the heating element cannot be directly touched by the hand because the heating element is built inside each rectifying plate. Therefore, the heating element may become hot during heating with a gas refrigerant or the like, but since it does not touch the heating element by mistake, it is safe for the user as described above.

  Further, during cooling, the condensed water condensed on the surface of the heating element is not touched by hand and is hygienic, and the user is not suddenly wet with the condensed water. Further, as described above, since the heating element itself is not subjected to external force, it is possible to prevent the heating element from being deformed or damaged by pressure or impact from the outside.

  Therefore, the strength against external force is not so much required, and any structure having at least the strength to withstand the pressure of the fluid can be used. This increases the choice of materials used for the heating element. Moreover, the danger of accidentally hitting the heat generating part and being injured can be reduced.

  Therefore, it can be used if the material has good thermal conductivity and the surface of the heating element has a high thermal emissivity, and even when using a liquid such as water or antifreeze, the pressure is low and even a material with a relatively low pressure resistance is used. Can be adopted. Also, a synthetic resin tube or a carbon fiber tube having a high surface heat radiation property and excellent water tightness can be employed.

In addition, when liquid layer refrigerant or refrigerant gas is used, the pressure is high, so that the pressure resistance is high and conductivity is good, for example, the surface of an aluminum refrigerant pipe or precision flat pipe is processed with high thermal emissivity. You can also use what you gave.
Since the synthetic resin tube and the carbon fiber tube are relatively lightweight, the weight of the apparatus can be reduced.

  Thereby, the burden of the carrying-in work and assembly work of the material in the case of installation work is reduced, and the cost of installation work can be held down. Further, by reducing the weight of the apparatus, for example, deformation stress during an earthquake is reduced, and reinforcement work for supporting the stress can be minimized. In this way, various restrictions in installation are reduced, and the risk of the device falling due to an earthquake is reduced. Therefore, it can contribute to the safety and security of the user.

  The heating element is not particularly restricted by the heat medium to be used, and can use high-temperature and high-pressure heat and high-pressure cold generated by an efficient refrigeration cycle of a heat pump heat source machine. It is also possible to use unused energy such as. In addition, if a synthetic resin pipe having excellent corrosion resistance is used, groundwater (hot water or cold water) can be directly passed through the heat generating body as an underground heat source, which is natural energy, for example, thereby obtaining an air conditioning effect.

  Furthermore, by using a material having a high far-infrared radiation capability for the heating element, or by applying surface treatment, the movement of the radiant heat is promoted, and as described above, the radiation effect of the heating element through the radiant heat transmission hole, It functions as a high-efficiency radiant air conditioner having a radiation effect from the surface of the rectifying plate having the radiant heat transmission holes.

  If both sides of each rectifying plate are closed with a closing member, and each rectifying plate and each closing member form a cylindrical body that surrounds the heating element and opens at the top and bottom, it is closed on both sides of each rectifying plate. Due to the presence of the members, the convection of the air passing between the current rectifying plates becomes a more ordered flow, and the chimney effect works more effectively.

  A guide member for guiding the air convection inside each rectifying plate to flow smoothly on the upper side and / or the lower side of the heating element is provided with air convection by the chimney effect using each rectifying plate. Furthermore, it can carry out efficiently.

  When the current plate is made of aluminum or a composite material containing aluminum, the heat transfer effect is excellent, and the efficiency of heat exchange with air is further improved.

  For advertisements, signs, pictures, or photographs displayed on the surface of the current plate, the current plate that functions as a protective cover in addition to the function that creates a chimney effect that promotes convection of the atmosphere is displayed on the advertising panel or sign. Can be used as

  The present invention arranges rectifying plates on both the front and back sides of the heating element of the air conditioner, promotes convection of the indoor air by the chimney effect and efficiently moves the heat, and then efficiently radiates the heat radiated from the heating element. Since it can be radiated well into the room, heat transfer by convection of room air and air conditioning by radiant heat can be combined to make the air conditioning in the room uniform.

The part (reference numeral omitted) is located slightly higher than the upper ends of the vertical frames 20 and 21.

Between the vertical frames 20, 21 constituting the frame 2, a heating element 1 made of synthetic resin such as polypropylene resin is attached with both ends fixed to the inner surfaces of the vertical frames 20, 21. Note that the frame 2 may be reinforced by forming a beam member at the upper, lower, or intermediate portion between the vertical frames 20 and 21.
The heating element 1 includes upper horizontal tubes 10 and 10a, and lower horizontal tubes 11 and 11a arranged in parallel to the upper horizontal tubes 10 and 10a at a predetermined interval downward. Both ends of the upper horizontal pipes 10 and 10a and the lower horizontal pipes 11 and 11a are liquid-tightly closed.

  The height at which the upper horizontal tubes 10 and 10a are arranged is set to a position slightly lower than the upper ends of the vertical frames 20 and 21. Further, the height at which the lower horizontal pipes 11 and 11 a are arranged is set at a position higher than the lower ends of the vertical frames 20 and 21.

  The upper horizontal pipe 10 and the lower horizontal pipe 11 on the front side (front side) are connected by a number of vertical pipes 12 provided in parallel with each other at a required interval. The upper horizontal pipe 10, the lower horizontal pipe 11, and each vertical pipe 12 are connected to each other. Communicate.

  Further, the lower horizontal pipe 11 and the lower horizontal pipe 11a adjacent to the front side and the rear side are connected and communicated with each other through communication pipes 13 formed at three locations. Below the lower horizontal pipes 11 and 11a, a bowl-shaped water collecting member 16 having an open top is arranged so that the lower horizontal pipes 11 and 11a enter the open part. The water collecting member 16 is horizontally fixed at a height that does not contact the lower horizontal pipes 11 and 11a with respect to the vertical frames 20 and 21, and a drain pipe 160 is connected to one end side.

  Further, a supply pipe 14 for supplying a heat medium is connected to and communicates with the right end of the upper horizontal pipe 10 in FIG. Similarly, a discharge pipe 15 for discharging the heat medium is connected to and communicated with an end portion of the upper horizontal pipe 10a adjacent to the back side of the upper horizontal pipe 10 on the same side.

  The supply pipe 14 and the discharge pipe 15 are formed vertically and penetrate the horizontal portion of the upper fixing member 27 in the vertical direction. The supply pipe 14 and the discharge pipe 15 are connected to a heat medium circulation device (not shown) (for example, using a heat pump), and in this embodiment, hot water or cold water can be circulated through the heating element 1. It is.

  In the present embodiment, a synthetic resin tube is used as the heating element 1, but the present invention is not limited to this, and heat generation of other known structures formed of a metal tube such as aluminum, for example. The body can also be adopted.

  On the front side of the vertical frames 20 and 21 of the frame 2, rectifying plates 3, 3a are detachably mounted, and on the back side, rectifying plates 4, 4a are detachably mounted. The rectifying plates 3 and 3a and the rectifying plates 4 and 4a are mounted by hooking a plurality of grooves formed in the bent portions on both side edge portions to pins formed on the inner surfaces of the vertical frames 20 and 21 on the front side and the rear side. It is a structure to do.

  The rectifying plates 3 and 3a and the rectifying plates 4 and 4a are attached in two upper and lower stages, respectively, and have a rectangular shape with a size capable of closing almost the entire width and height of the frame 2. Gaps 39 and 49 through which air flows are formed between the heating element 1 and the rectifying plates 3 and 3a and the rectifying plates 4 and 4a.

  The rectifying plates 3 and 3a and the rectifying plates 4 and 4a are made of a composite material containing aluminum, and are punched in which a large number of radiant heat transmission holes 30 and 40 are formed so as to penetrate the front and back surfaces over almost the entire surface while leaving a part of the peripheral portion Metal (or punching board). The inner surfaces of the rectifying plates 3 and 3a and the rectifying plates 4 and 4a are reflecting surfaces 31 and 41 that reflect radiant heat. The aperture ratios of the radiant heat transmission holes 30 of the rectifying plates 3 and 3a and the radiant heat transmission holes 40 of the rectifying plates 4 and 4a are set to 50%.

  The arrangement and number of the radiant heat transmission holes 30 and 40, the shape of the holes, and the aperture ratio are not particularly limited, and can be appropriately set with various designs. In the present embodiment, the reflective surface 31 and the reflective surface 41 are embossed to promote irregular reflection of radiant heat to form a large number of fine irregularities.

  Since the rectifying plates 3 and 3a and the rectifying plates 4 and 4a are formed of aluminum, the heat transfer effect is excellent and the efficiency of heat exchange with air is further improved. In addition, as a material of each rectifying plate 3, 3a, 4, 4a, in addition to a composite material containing aluminum and aluminum, various metal plates such as stainless steel with an emphasis on designability, glass plates, or synthetic resin plates may be adopted. Good.

  Further, the rectifying plates 3, 3a and the rectifying plates 4, 4a have a peripheral edge that protrudes from the peripheral edge of the heating element 1, and has a surface wider than the heating element 1 in a front view. The upper ends of the rectifying plates 3, 3 a and the rectifying plates 4, 4 a are set flush with the upper ends of the vertical frames 20, 21 of the frame 2, and the lower ends of the rectifying plates 3, 3 a and the rectifying plates 4, 4 a are It is set at a position slightly above the lower ends of the vertical frames 20 and 21.

  The front side rectifying plates 3 and 3a, the rear side rectifying plates 4 and 4a, and the vertical frames 20 and 21 on both ends in the width direction are integrated to form an upper opening 28 at the upper end and a lower portion at the lower end. It becomes a somewhat flat rectangular cylinder having the opening 29. Thus, since the structure surrounding the heating element 1 is a cylinder, the chimney effect that promotes convection is more excellent.

  By setting the sizes and mounting positions of the rectifying plates 3, 3a and the rectifying plates 4, 4a as described above, the room unit R1 of the air conditioner is connected to the floor surface 5 and the ceiling surface 6 as shown in FIG. When fixed to the floor, a lower gap 50 is formed between the floor surface 5 and the lower ends of the rectifying plate 3a and the rectifying plate 4a, and an upper gap is provided between the ceiling surface 6 and the upper ends of the rectifying plate 3 and the rectifying plate 4. 60 is formed.

(Function)
The operation of the room unit R1 of the air conditioner will be described with reference to FIGS.
First, as shown in FIG. 3, the room unit R1 of the air conditioner is fixed to the floor surface 5 by the lower fixing members 24, 25 at a position slightly separated from the wall surface 8, and the upper fixing members 26, 27 fix the ceiling. Fixed to surface 6 and installed indoors.

  When the room is heated by the room unit R1 of the air conditioner, a high-temperature heat medium is supplied from the supply pipe 14 to the heating element 1 and circulates, and the heating element 1 is heated and heat is generated. As a result, the air in the vicinity of the heating element 1 is heated by radiant heat, and natural convection of air from the bottom to the top is generated along the heating element 1 (in the following description of the air flow, FIG. ) For reference).

  Thus, external air flows from the gap 50 on the lower floor 5 side through the lower opening 29 between the rectifying plates 3 and 3a and the rectifying plates 4 and 4a. The convection is continued by the inflowing air being heated by the heating element 1 while moving up the gaps 39 and 49 inside the current plates. In addition, a sufficient flow rate of convection air is ensured by the chimney effect provided by the rectifying plates 3, 3 a and the rectifying plates 4, 4 a on both sides of the heating element 1.

  The heated air rising through the gaps 39 and 49 passes through the upper opening 28 between the rectifying plates 3 and 3a and the rectifying plates 4 and 4a and is discharged to the outside from the gap 60 on the upper ceiling surface 6 side. The discharged air has an increased flow velocity due to the chimney effect, and reaches a position away from the room unit R1 of the air conditioner along the ceiling surface 6. In addition, air is cooled by heat exchange along with this movement and descends. In this way, the indoor air circulates throughout the room while being heated by the heating element 1.

  On the other hand, a part of the radiant heat radiated from the heating element 1 (in this embodiment, since the opening ratio of the radiant heat transmission holes 30 and 40 is 50%, the transmission ratio is the lower opening 29 and the upper opening. In consideration of what passes through the portion 28, it is considered that about 50% of the total radiant heat) is released into the room through the radiant heat transmission holes 30, 40 formed in the rectifying plates 3, 3a and the rectifying plates 4, 4a. The Thereby, radiant heat is used directly and effectively to warm the temperature of indoor air.

  Of the radiant heat radiated from the heating element 1, the radiant heat that could not pass through the radiant heat transmission holes 30, 40 is reflected on the inner surfaces of the rectifying plates 3, 3a and the rectifying plates 4, 4a, Further, irregular reflection occurs between the heat generating body 1 and the reflecting surfaces 31 and 41 of the other rectifying plates facing each other. Thereby, a part of the radiant heat is released into the room through the respective radiant heat transmission holes 30 and 40, and a part thereof is from the lower opening 29 and the upper opening 28 between the rectifying plates 3 and 3a and the rectifying plates 4 and 4a. Released into the room. Further, a part of the rectifying plates 3 and 3a and the rectifying plates 4 and 4a are heated to raise the temperature, and the outward radiant heat from each rectifying plate is released into the room.

  As described above, according to the room unit R2 of the air conditioner according to the present embodiment, while the reflection and release of the radiant heat as described above are repeated, the room is well heated by the radiant heat together with the heat moving by the convection of the air. The entire room can be effectively air-conditioned, and the temperature and humidity can be made uniform.

  When cooling indoors, unlike the case of heating, air is cooled by the heating element 1 to generate cold heat, so the air along the heating element 1 and the rectifying plates 3, 3a and the rectifying plates 4, 4a The convection is cooled downward from above, and the flow of the cooled air is almost opposite to that in the case of heating (for the sake of convenience, refer to FIG. 6B described later for convenience).

  In addition, when air convects at a required flow velocity along the rectifying plates 3, 3a and the rectifying plates 4, 4a during heating and cooling, the radiant heat transmission holes 30, 40 are caused by the venturi effect. Since the outside air is taken in from this, the movement of this air also promotes convection, and the air conditioning of the whole room can be performed more effectively.

  Further, as described above, when heating and cooling the room, the heating element 1, the frame 2, the rectifying plates 3, 3a, and the rectifying plates 4, 4a expand and contract, and the length in the vertical direction is relatively large. Change. Accordingly, as shown in FIGS. 6A and 6B, the height of the water collecting member 16 changes, but the drain pipe 160 is inserted into the drain pipe 161 so as to freely enter and exit during installation. Because of the structure, the amount of change can be absorbed.

Please refer to FIG.
The room unit R2 of the air conditioner includes a lower guide member 17 that guides convection air to the lower part of the heating element 1, and an upper guide member 18 on the upper part of the heating element 1. The lower guide member 17 is composed of two curved plates (reference numerals omitted) having a required length in the vertical direction and substantially the same width as the length of the lower horizontal tubes 11 and 11a of the heating element 1. The water member 16 is fixed facing the front side and the back side.

  Further, the upper guide member 18 is composed of two curved plates (reference numerals omitted) having a required length in the up and down direction and having substantially the same width as the length of the upper horizontal tubes 10 and 10a of the heating element 1. Is fixed to the front side and the back side of the upper horizontal tubes 10 and 10a. In addition, although the raw material of the lower guide member 17 and the upper guide member 18 is various metals or a synthetic resin, it is not limited to these.

  The room unit R2 of the air conditioner is provided with the lower guide member 17 and the upper guide member 18, so that air flows smoothly, and the chimney using the rectifying plates 3, 3a and the rectifying plates 4, 4a Air convection due to the effect can be performed more efficiently.

Please refer to FIG.
On the surface of the rectifying plates 3 and 3a on the front side shown in FIG. 7, in FIG. 7A, advertising characters expressing the “ecowin” logo in the vertical direction from the rectifying plate 3a on the lower side to the rectifying plate 3 on the upper side. 7a is printed. Further, in FIG. 7B, advertising characters 7 b expressing the “ecowin” logo in the horizontal direction are printed on the surface of the upper rectifying plate 3. In addition, advertising characters can be printed on the back side rectifying plates 4 and 4a in the same manner. What is expressed on each rectifying plate is not limited to advertisements, signs (signs and signboard displays), and various designs, but various artistic expressions such as pictures and photographs can also be employed.

  Thereby, in addition to the functionality which produces the chimney effect which accelerates | stimulates the convection of atmosphere, the baffle plates 3, 3a, 4, 4a which have the functionality as a protective cover can be utilized as an advertising panel or a sign. That is, the room units R1 and R2 of the air conditioner have a form that is greatly exposed to the indoor space where they are installed, and have a presence.
