Description

[Technical Field]

[0001] The present invention relates to a room structure of, for example, an apartment building. [Background technology]

[0002] Traditionally, rooms in apartment buildings and other housing have been designed based on the size, facilities, and wishes of the residents. In recent years, in light of the Sustainable Development Goals (SDGs) and environmental issues, attention has been focused on ZEH (Net Zero Energy Houses), which achieve significant energy savings by improving insulation performance and introducing highly efficient equipment, as well as reducing energy consumption by introducing renewable energy.

[0003] For example, Patent Document 1 discloses a technology in which a latent heat storage material is built into the bathroom door or living room door of a washroom located between a specified living room and the bathroom, and the phase of the latent heat storage material changes depending on the temperature difference between the living room and the washroom or the temperature difference between the bathroom and the washroom, making it difficult for the temperature in the washroom to drop. Also, the living room is configured to be equipped with a heating device so that the indoor temperature does not drop too much, even in winter (see paragraphs "0031" and "0032"). [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Japanese Patent Application Laid-Open No. 2018-105099 Summary of the Invention [Problem to be solved by the invention]

[0005] However, in Patent Document 1, the washroom is difficult to heat unless it is adjacent to a living room and a bathroom. In other words, the desired effect is difficult to achieve unless the spaces are adjacent. However, because the washroom is smaller than the living room and tends to be hotter, it is difficult to obtain warm air from the living room and store heat. In reality, the washroom has no choice but to obtain warm air from the bathroom and store heat. Furthermore, because the washroom is originally prone to being heated by receiving hot air from the bathroom, not only is it difficult to experience the heating effect of the latent heat storage material, but it is also difficult to cool down due to heat dissipation from the latent heat storage material, which may result in sweating after bathing.

[0006] Furthermore, in a ZEH with high insulation specifications, even if there are multiple living rooms, it is easy to achieve energy savings by simply operating the heating device in the living room, for example, and to create an environment with little temperature difference throughout the entire residence, including distant bedrooms and children's rooms. However, in reality, if the living room is used with the hallway door closed, or if the bedrooms and children's rooms are used with the partition doors closed, it is difficult to reduce the temperature difference. In other words, the inventors have come to the challenge of reducing the temperature difference between rooms that are not adjacent by utilizing phase change materials.

[0007] Therefore, the object of the present invention is to provide a room structure and a method for heating a room structure that can easily and efficiently heat other rooms that are not adjacent to a specified room using a heating device installed in the specified room. [Means for solving the problem]

[0008] In other words, the present invention is a room structure for a building comprising a first room that can be heated by a heating device, a corridor connecting to the first room, and a second room with a partition door on the corridor side, wherein the partition door incorporates a latent heat storage material that changes phase depending on the temperatures on the corridor side and the second room side, and the latent heat storage material radiates heat into the second room closed by the partition door when the temperature on the second room side is lower than the corridor side that is heated together with the first room by the heating device and falls below the phase change temperature.

[0009] With this configuration, warm air from the first living room is transferred to the hallway, reducing the temperature difference between the first living room and the hallway. The latent heat storage material in the partition door dissipates heat in response to the temperature of the second living room, which is cooler than the hallway, warming the second living room. This makes it easier to maintain a desired environment in the second living room even when the partition door is closed. In other words, it is easier to maintain a uniform temperature throughout the entire living room, including the second living room, using only the heating device in the first living room. Furthermore, if the heating in the first living room is constantly running, warm air is also maintained in the hallway, so the heat dissipated to the second living room can be stored in the hallway.

[0010] The following provides definitions and examples of the technical elements that constitute the living space structure of the present invention.

[0011] "Buildings" include, for example, apartment buildings, detached houses, temporary housing, schools, hospitals, elderly care facilities, facilities for the disabled, and various commercial facilities, and are not limited to structures or sizes such as reinforced concrete, steel-reinforced concrete, or steel frame construction. When the "building" is an apartment building, the specifications of each room within the apartment building in which the present invention is implemented, such as the number of rooms, size, structure, and construction method, are not limited, but preferably meet the ZEH standards. The ZEH standards are those published on the Internet by the Agency for Natural Resources and Energy, Ministry of Economy, Trade and Industry, in "Definition of ZEH (Revised Edition) <Detached Houses> February 2019" or "Definition of ZEH (Revised Edition) <Apartment Buildings> March 2019."

[0012] The living space structure of an apartment building is not limited to two living spaces, such as a "first living space" and a "second living space," but may include three or more living spaces. Each of the living spaces included in the living space structure may be Western-style or Japanese-style, and may be, for example, a living room, living-dining room, living-dining-kitchen room, bedroom, children's room, or study, with no restrictions on size or shape. The living space structure may also include, in addition to the living spaces, a hallway, a washroom, a bathroom, a toilet, a kitchen, a storeroom, or a walk-in closet. The floor plan of the living space structure may be one living room, one dining room, one kitchen, or a kitchen, and may be, for example, a square-shaped, wide-span, corner, or center-in type.

[0013] A "corridor" is a long, narrow space that connects the first and second living rooms, sandwiched between partition walls, partition doors, and other fixtures that form each living room.It may connect to the entrances and exits of the first and / or second living rooms from either the longitudinal or lateral direction, and may be flat with no difference in elevation from the first and / or second living rooms, or stepped with a difference in elevation.However, it is preferable that the corridor connects in a straight line from the longitudinal direction to the entrance and exit of the first living room so that warm air from the first living room can be easily transported to the second living room, and it may connect to the entrance hall in a straight line or in a crank-like manner.

[0014] A "partition door" is a door formed to serve as an entrance / exit for or to open / close each room, including the second room. It may be a hinged door or a sliding door, installed in an opening in a fixed partition wall that forms each room, or it may be at least one of multiple panels that form a movable partition wall that can be folded or slid. There are no restrictions on size or shape, as long as it is made of a wooden, resin, or metal base material or board and has the thickness and space to accommodate a built-in latent heat storage material. The fixed partition wall may be made of a base material, gypsum board, or the like, and preferably does not contain a built-in latent heat storage material in order to effectively implement the present invention.

[0015] "Latent heat storage material" refers to a pack or coated sheet material containing raw materials such as paraffin, and may be attached preferably to the back of the board facing the second living room to be heated, or may be attached to almost the entire surface of the partition door or may be attached in scattered patterns over the entire surface, or may be attached in one or more of the following places on the partition door: the top, center, bottom, near the top end, near the bottom end, near one side end, or near both ends, and there are no restrictions on the size, shape, or amount of raw materials.

[0016] The "phase change temperature of the latent heat storage material" may be set according to the temperature of each room or the temperature near spaces other than the rooms, for example, 15 to 20°C. If the temperature on the second room side is lower than 18°C ​​at night, etc., and the material does not absorb or release heat, the second room may become cold and may be harmful to health, and if the temperature on the second room side is higher than 22°C during the day, etc., and the material does not absorb or release heat, the second room may become hot and uncomfortable, and energy efficiency may also decrease.

[0017] The "heating device" may be any device capable of heating the first living room, such as an air conditioner mounted on the wall of the first living room, an electric floor heating system or carpet installed on the floor, a portable electric fan heater or fossil fuel stove, or a combination of two or more types. To effectively implement the present invention, it is preferable that no heating device is installed in the hallway or second living room, or that even if a heating device is installed, it is not in operation.

[0018] A more desirable configuration for the room structure of the present invention will be described below.

[0019] The above-mentioned living space structure further includes an entrance hall that is connected to the corridor and located near the second living space, and the phase change temperature of the latent heat storage material is desirably set according to the temperature near the entrance hall. The temperature near the entrance hall is 17 to 18°C. With this configuration, since the entrance hall is easily exposed to outside air and cools relatively easily, it is expected that the latent heat generating material can be dissipated to heat the second living space before it becomes too cold.

[0020] The first living room is a living room, living-dining room, or living-dining-kitchen room, and the second living room is preferably smaller than the first living room. With this configuration, the first living room is used most frequently, and therefore the heating device's operating rate and heating efficiency are high, making it easier to efficiently heat the second living room, which is smaller than the first living room, and this is expected to have the effect of reducing temperature differences between the first living room, the hallway, and the second living room.

[0021] The hallway has a hallway door that can be opened and closed to the first living room, and the hallway door preferably has an air vent that allows warm air from the first living room to pass through. With this configuration, the hallway door can be closed to ensure a private space for the first living room and increase heating efficiency, while also making it easier for warm air from the first living room to be transmitted to the hallway, which is expected to have the effect of making it easier to reduce the temperature difference between the first living room and the hallway.

[0022] A "corridor door" is a hinged door that separates the first living room from the corridor. It may be attached to the boundary between the first living room and the corridor, and may be formed with a wooden, resin, or metal base material or board, and there are no restrictions on size or shape. The "air vent" may be a small circular or rectangular through-hole formed in the corridor door, but in consideration of design and the blind effect, it is preferably a slit, and more preferably the gap between the individual blades that make up the louvers attached to a larger through-hole formed in the corridor door.

[0023] The present invention also provides a method for heating a room structure in a building that includes a first room that can be heated by a heating device, a corridor that connects to the first room, and a second room that has a partition door on the corridor side that contains a phase storage material, wherein the phase storage material undergoes a phase change in response to temperatures on the corridor side and the second room side, and when the temperature on the second room side becomes lower than the corridor side that is heated together with the first room by the heating device with the partition door closed, heat is released from the phase storage material into the second room. The effects that can be expected from this method are similar to those obtained with the above-mentioned room structure. [Effects of the Invention]

[0024] According to the present invention, it is expected that the heating device of a given room can be used to efficiently heat other rooms that are not adjacent to the given room. [Brief explanation of the drawings]

[0025] [Figure 1] FIG. 1 is a plan view of a room structure according to an embodiment of the present invention. [Figure 2] FIG. 2 is an enlarged end view of a portion AA in the plan view. DETAILED DESCRIPTION OF THE INVENTION

[0026] Hereinafter, a room structure (hereinafter also referred to as "this room structure") and its heating method according to one embodiment of the present invention will be described with reference to Figures 1 and 2. In these figures, when there are multiple identical parts, only one part is numbered. For the sake of convenience, certain parts and their leading lines are sometimes shown as hidden lines (dashed lines). In the explanation, terms indicating directions such as up, down, side, vertical, and horizontal are basically based on a normal building, and when other references are used, they will be explained appropriately.

[0027] <Outline of the room structure> As shown in Figure 1, this room structure relates to room R on a given floor of an apartment building, and the layout of room R is a 3LDK (three-bedroom, living and dining) layout with at least a first room 1 that can be heated by a heating device 11 and includes a kitchen K, a hallway 3 that leads to the first room 1, a second room 2 that has a partition door 21 on the hallway 3 side, and a foyer 4 that leads to the hallway 3 and is located near the second room 2. The arrows in Figure 1 indicate the direction of warm air that flows when the heating device 11 is operating.

[0028] In other words, to explain in detail, this living room structure is rectangular in plan view, and on one side of the structure, which is divided approximately in half longitudinally, it has, from the balcony V side, a first living room 1, a kitchen K included in the first living room 1, a second living room 2 adjacent to the kitchen K, a corridor 3 that connects to the first living room 1 and extends along the partition wall of the second living room 2, and a front door 4 that connects to the corridor 3 and is adjacent to the second living room 2; on the other side, from the balcony V side, it has a third living room R1, a toilet T adjacent to the third living room R1, a bathroom B which includes a washroom and changing room adjacent to the toilet T, and a fourth living room R2 adjacent to the bathroom B; and in the short side, the first living room 1, the third living room R1, the toilet T, and the bathroom B are adjacent to each other, and the second living room 2 and the fourth living room R2 are adjacent to each other across the corridor 3 and the front door 4.

[0029] <Details of Room 1, Heating Unit 11, Kitchen K> The first living room 1 is used as a living, dining, and kitchen room and is the largest of the living rooms. The first living room 1 has a heating unit 11 attached to the interior side of the wall facing the balcony V. The first living room 1 may have a bay window or high sash window (not shown) at the boundary with the balcony V, and may be heated by sunlight entering through these windows during the day. The heating unit 11 is located near the corner formed by the ceiling and wall of the first living room 1, but it may also be located in a position aligned with the hallway 3, for example. The location is not limited as long as it can heat the first living room 1. The kitchen K has a waist-high counter equipped with a sink and stove, and is positioned so that the first living room 1 can be viewed from the counter. The kitchen K can be heated by the heating unit 11.

[0030] <Details of Room 2> The second living room 2 is a Western-style room used as a child's room or bedroom and is smaller than the first living room 1. The floor area of ​​the second living room 2 may be 1 / 10 to 9 / 10 of the floor area of ​​the first living room 1, but in consideration of heating efficiency, it is preferably 3 / 10 to 7 / 10, and more preferably 4 / 10 to 6 / 10. The second living room 2 is formed in a roughly rectangular shape by an exterior wall facing an external corridor (not shown) that leads to the entrance 4 and a partition wall. An entrance formed in the partition wall is on the corridor 3 side, and the second living room 2 is adjacent to the kitchen K and entrance 4 via the partition wall. The second living room 2 may be designed so that a specified heating device can be installed on the indoor side of the exterior wall, and may have a waist-high window in the exterior wall.

[0031] <Details of Partition Door 21> The partition door 21 is formed based on known technology using a wooden or resin base material or board, and is a single-sided sliding door that opens and closes the entrance to the second room 2. However, it may be a double-sided sliding door, and may slide on a roller on a rail installed on a flat floor, or on a hoist on a rail installed on a lintel, or may have an offset structure. As shown in FIG. 2, the partition door 21 incorporates a phase change material 21a. The phase change material 21a is a packed material containing raw materials such as paraffin, and is affixed to substantially the entire inside of the partition door 21. The phase change material 21a is incorporated when the partition door 21 is manufactured at a factory, and does not necessarily have to be incorporated during the installation work at the construction site. In this case, the partition door 21 may be distributed separately.

[0032] <Details of Phase Change Material 21a> As shown in Figures 1 and 2, the phase change temperature of the latent heat storage material 21a is set to 17 to 18°C, which is the temperature near the entrance 4. The arrows in Figures 2(a) and 2(b) indicate the direction of heat absorption and release by the latent heat storage material 21a. With the partition door 21 closed, for example, if the temperatures on both the hallway 3 side and the second living room 2 side reach 20°C or higher during the daytime, as shown in Figure 2(a), the latent heat storage material 21a absorbs heat from both the hallway 3 side and the second living room 2 side. On the other hand, as shown in Figure 2(b), if the heating device 11 in the first living room 1 is operated during the nighttime, and the temperatures on both the first living room 1 and the hallway 3 side are 20°C or higher and the temperature on the second living room 2 side is lower than 20°C, the latent heat storage material 21a releases heat to the second living room 2 side. Depending on the durability of the packing material, the latent heat storage material 21a may not require inspection or replacement.

[0033] <Details of Hallway 3 and Entrance 4> As shown in FIG. 1, the hallway 3 is a long, narrow passage-like space formed by the partition wall forming the second living room 2, the partition wall forming the fourth living room R2, and the floor. The hallway 3 is directly connected to the entrance of the first living room 1 in a straight line, and may have a hallway door at the boundary with the first living room 1. The entrance 4 is directly connected to the hallway 3 from the opposite side of the first living room 1, in other words, it is connected to the first living room 1 in a straight line via the hallway 3. Since the entrance 4 is smaller than the first living room 1, it may be heated via the hallway 3 by warm air from the first living room 1.

[0034] <Details of hallway door 31> As shown in FIG. 1, the corridor door 31 has louvers. The louvers are attached to predetermined locations on the corridor door 31 and may be attached to any one or more of the upper, middle, or lower floors of the corridor door 31, either the upper or lower half, or substantially the entire surface. The angle of each blade constituting the louver may be horizontal, but is preferably 30 to 60 degrees diagonally downward from the first living room 1 toward the corridor 3, and more preferably 40 to 50 degrees to obtain a shielding effect for the first living room 1 from the corridor 3. The blades may be fixed or adjustable relative to the corridor door 31. The width of the blades is 50 to 120 mm. If the width is narrower than 50 mm, the number of blades will be too large, resulting in a narrow air passage, which may reduce ventilation efficiency. If the width is thicker than 120 mm, the number of blades will be too small, resulting in a wide air passage, which may reduce the shielding effect.

[0035] <Effects of this room structure> Therefore, with this living room structure, the warm air from the first living room 1 generated by the heating device 11 is transferred to the hallway 3, easily reducing the temperature difference between the first living room 1 and the hallway 3, and the latent heat storage material 21a inside the partition door 21 radiates heat in response to the temperature of the second living room 2, which is cooler than the hallway 3, thereby warming the second living room 2, so that the desired environment in the second living room 2 can be maintained even with the partition door 21 closed. In other words, the entire living room, including the second living room 2, can be maintained at a uniform temperature using only the heating device 11 in the first living room 1. Because the entrance 4 is easily exposed to outside air and cools relatively easily, the latent heat storage material 21a can radiate heat and heat the second living room 2 adjacent to the entrance 4 before it becomes too cold. Since the first living room 1 is used most frequently, the operating rate and heating efficiency of the heating device 11 are also high, making it easier to efficiently heat the second living room 2, which is smaller than the first living room 1, and reducing the temperature difference between the first living room 1, the hallway 3, and the second living room 2. The hallway door 3 allows the first living room 1 to have a private space without reducing the heating efficiency of the hallway 3.

[0036] In other words, with this room structure, there is no need for special equipment such as a whole-building air conditioning system that connects each room with ducts, etc., so the initial costs and operating and maintenance costs are relatively low; there is no need for gaps at the bottom of the partition door 21, which would make it easier for warm air to flow from the corridor 3 into the second room 2, so soundproofing and privacy for the second room 2 can be ensured; and there is no need to thin the partition door 21 to increase the heat return rate, so a decrease in the strength and quality of the partition door 21 can be avoided.

[0037] The room structure shown in this embodiment is not limited to the above-mentioned content, and includes the positions, shapes, and dimensions of all parts and the relationships between parts as long as the same effect can be obtained.

[0038] For example, latent heat storage material may be incorporated into the partition wall R1a of the third living room R1, and into the partition wall R2a of the fourth living room R2, so that they can be heated in the same way as the second living room 2. Because the third living room R1, which is adjacent to the first living room 1, heats up relatively more easily than the second living room 2 and the fourth living room R2, which are adjacent to the entrance 4, the phase change temperature of the latent heat storage material incorporated into the partition wall R1a may be set higher than the phase change temperature of the latent heat storage material 21a, for example, to 21°C.

[0039] <An example of how to heat this room structure> If the temperature of first living room 1 is 20°C or lower, heating device 11 heats first living room 1 to at least 20°C, and warm air is circulated from first living room 1, so that after a predetermined time, the temperature of hallway 3 becomes equal to that of first living room 1. If the temperature of second living room 2 is 20°C or lower, latent heat storage material 21a detects the temperature difference between hallway 3 and second living room 2, and radiates heat from latent heat storage material 21a until the temperature of second living room 2 reaches 20°C. When the temperature difference between hallway 3 and second living room 2 disappears, heat radiation from latent heat storage material 21a automatically stops. [Explanation of symbols]
