Abstract

PROBLEM TO BE SOLVED: To reduce a temperature difference depending on a place of a room and a temperature difference between an upper space and a lower space in the same place by arranging a radiator at a specified distance from a lower wall surface of a cool air inlet to the interior, and arranging a panel body in front of the interior side of the radiator. SOLUTION: A room of an office building is provided with a large glass window 2 on a wall surface for example, a radiator 7 is arranged at a specified distance A on the side of a lower wall of the glass window 2, and a panel body 8 is arranged at a specified distance B in front of the radiator 7. When the heating starts, heat is radiated from the radiator 7, but radiant heat of the radiator 7 toward the side of the interior of a room 1 is reduced by a heat insulating material and low radiant efficiency of the panel body 8, the heat turns into convective heat and rises, and reaches further toward the side of the interior of the room 1 or toward the inner part thereof along a ceiling 3. As a result, air flow of a chill generated along the glass window 2 is prevented from entering the inside of the room 1 by an ascending current during heating.

2. Description of the Related Art In recent years, there has been a tendency to increase the window area in office buildings and the like in order to improve the lighting and the view. In particular, in the winter season, the temperature environment in the room at the time of heating changes greatly due to the influence of cold air or the like entering from the window, and an uneven temperature distribution occurs in the room. In particular, when using a radiator that dissipates heat by radiation and convection, such as a steam radiator without a fan, to heat the room, the person near the radiator is very hot due to radiant heat, People far away feel cold because the radiant heat is obstructed by people and objects on the way and the heat due to convection is weak.

For example, in a situation where a steam-type radiator is disposed under a window in a room and heating is performed, when the heating is ON, the surface temperature of the radiator becomes 100 ° C. (actual measurement value) at the maximum and 20 to 3 degrees.
A person sitting at a close distance of 0 cm has a very hot and unpleasant environment because of the strong radiation and the uneven radiation in which only one side of the body receives radiant heat. On the other hand, those who are far away are very cold because the radiant heat is blocked by the desks and bookshelves, and the coat does not come off. In addition, there is a problem that the feet cool down due to a large vertical temperature difference. In ISO-7730, the temperature difference between the ankle (0.1 m above the floor) and the head (1.1 m above the floor) when seated is 3
It is specified that it is uncomfortable when the temperature is higher than ° C. In the case of intermittent heating such as steam heating, a cold draft (cold airflow) often occurs when the heating is turned off, and the resulting coldness at the feet causes a problem in terms of warmth.

[0004]

SUMMARY OF THE INVENTION Accordingly, the present invention is to dispose a panel body made of a heat insulating material having a predetermined size and a low radiation material on the front surface (inside of a room) of a conventional radiator such as steam heating. By converting the radiant heat of the conventional radiator into the amount of convective heat, the difference in temperature between places in the room is reduced, and the temperature difference between the upper and lower spaces in the same place is reduced. By strengthening the draft effect of the airflow, the temperature difference between the ON and OFF states of heating is reduced, thereby solving the above problem.

According to the present invention, it is possible to prevent the low-temperature air flowing from the window from diffusing into the room by attaching the panel to the front of a heater having no fan. By attaching a panel to an existing radiator without changing the radiator without a fan, which is widely used in general buildings, the radiation characteristics can be significantly improved. Since this panel body can convert radiant heat to convective heat, the radiant heat of the radiator does not reach closer to the heat insulating material and the indoor panel with low emissivity, but increases as convective heat, It is possible to reach the far side of the indoor side, thereby making it possible to equalize the spatial temperature field in the vertical and horizontal directions. Cold draft along the window surface can be prevented irrespective of whether the heating is ON or OFF, and the temperature difference between various positions in the room when the heating is OFF can be reduced, and the feeling of warmth can be improved. Since there is no power and only the panel body is installed around the existing radiator, there is no necessary work on the building itself, so it can be easily installed. The space near the radiator is difficult to use due to hot or cold airflow, but by installing this panel body the temperature difference can be eliminated and the room can be used widely, and the layout of the room Will be free.

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a schematic sectional view of a room in which a heating device according to an embodiment of the present invention is arranged. In the figure, 1
Is one of the rooms in a normal office building heated by the present heating device. This room has, for example, a large window 2 on one wall surface, and other ceilings 3, peripheral side walls 4, and floor 5 are conventional rooms. It is configured similarly to

The window 2 is made of a material such as glass, the wall below the window is formed as a wall having a predetermined thickness as in the prior art, and the connection between the wall below the window and the window is as shown in the figure. Is formed as an inclined surface 6 which is inclined downward toward the indoor side. The configuration of the room is merely an example, and is not different from the conventional one, and is not a feature of the present invention.

A conventionally known radiator 7 (for example, a steam radiator) is disposed at a predetermined distance A on the side of the wall below the window, and a predetermined distance B is provided on the front surface of the radiator 7. A panel body 8, which will be described later, is arranged at a distance. The radiator 7 is not limited to the steam radiator 7 and is preferably a radiator without a fan widely used in general buildings, but a radiator with a fan can also be used.

The panel body 8 is basically made of a material C,
D and E, and the material C has a function of preventing radiant heat from the radiator 7 and storing heat. The surface on the radiator 7 side has a material having a small emissivity (for example, aluminum). Panel, aluminum foil, etc.), and appropriately combined with a material having a heat storage effect (for example, concrete, black painted brick, latent heat storage material, etc.). With such a configuration, the radiant heat from the radiator 7 can be converted into convective heat, and the heat storage is performed by the heating OF.
It plays a role in reducing the temperature drop in the room at the time of F.

The material D is a heat insulating material (for example, glass wool) having a heat insulating effect for preventing heat from the radiator 7 from being transmitted to the room. Generally, it is sufficient that the distance is 50 mm or more. Excessive radiant heat on the side of the radiator 7 is prevented. The material E has a panel corresponding to the interior of the room, but this material is not always necessary.

The operation of the heating device having the above configuration will be described. In the room, a downward cold airflow (cold draft) is generated along a glass material g (a cold surface such as a glass surface or an outer wall) forming a window, and cool air is sucked into the room from this portion. Assuming that the thickness of the boundary layer of the cold draft is δm, the height of the window is hm, the window width is constant, and the difference between the room average temperature and the glass surface temperature is ΔT ° C, δ = 0. .048h ^1/4 ΔT ^1/4 .

In the case of a general office, the height of the window surface h =
Assuming 2 m, room temperature 20 ° C., glass surface 12 ° C., and thus T = 8 ° C., the boundary layer thickness is 9.6 cm. In the state where the cold airflow is generated as described above, a conventionally known radiator 7 is arranged at a distance A. At this time, the heat generation amount Q1 [W] of the radiator 7 is Q1 ≧ Q2, where the heat amount escaping from the g (window or wall) is Q2 [W]. For example, the size of each radiator 7 is usually about 1 m in height and about 0.5 m in depth, and the width along the window surface or wall surface depends on the cold in the area or the temperature of the heating heat medium.
It is about 4 m to 2 m. Further, the panel body 8 disposed on the front surface of the radiator 7 is formed to have a size equal to or larger than the area of the front surface of the radiator 7, and a predetermined distance (airflow is generated) around the front surface of the radiator 7. The shape may be such that it is surrounded by such an interval.

In the above configuration, when heating is ON,
Although the heat is radiated from the radiator 7, as shown in FIG. 2, the radiant heat of the radiator 7 to the indoor side is reduced by the heat insulating material of the panel body 8 and the low emissivity, while the heat becomes convective heat. It rises as shown in the figure and reaches farther and further back on the indoor side along the ceiling. In this way, the cool airflow generated along the window surface can be prevented from entering the room due to the rising airflow during heating.

When the heating is turned off, as shown in FIG. 3, the cold draft along the window surface is smoothly formed between the radiator 7 and the wall surface along the inclined surface formed on the wall surface under the window. The heat is sucked from the suction port and heated by the heat stored in the radiator 7, and the heat becomes convective heat and is blown out from the blowout port formed between the radiator and the panel body and rises as shown in the figure. . At this time, the suction port formed between the radiator 7 and the wall surface and the discharge port formed between the radiator 7 and the panel body 8 have the same size as the developed boundary layer thickness. If the pressure loss is suppressed by reducing the pressure, the descending airflow can be changed to the ascending airflow by the cold draft, whereby the invasion of cool air from the window can be prevented and the room temperature can be prevented from lowering.

The panel body 8 has a function of preventing heat radiation from the radiator 7 and having a function of storing heat, and has a heat insulating effect for preventing heat from the radiator 7 from being transmitted to the room. In the embodiment described above, the heat storage material is not required when the heat storage function at the time of heating OFF is not required, and the panel body 8 prevents the radiant heat from the radiator 7 and the radiator side. And a material having a heat insulating effect for preventing heat from being transmitted to the room. The heat storage material may be detachable as needed according to the heat storage capacity. Further, the panel body 8 can be used also as a fence for preventing burns. Further, as long as the shape of the panel body can perform the above function, various shapes can be adopted, for example. Furthermore, the present invention can be implemented in various forms within the scope of the present invention.

(2) By using this heating device, the radiant heat can be converted to convective heat, so the radiant heat of the radiator does not reach closer to the heat insulating material and the indoor panel with low emissivity and becomes convective heat. And rises further, reaching farther into the room.

(3) Turn the cold draft on the window surface ON / OFF
Irrespective of the temperature, it is possible to reduce the temperature drop when the heating is turned off and to improve the feeling of warmth. (4) Since there is no power and only the existing radiator is installed around the radiator, there is no need for construction work on the building itself, so that there is an energy saving effect. (5) Maintenance is unnecessary because there is no moving part. (6) Since it is basically a combination of panels, it can be produced at low cost. (7) The surface of the radiator has a maximum temperature of 100 ° C, but by installing this device, you will not be burned by directly touching it. (8) There were cases where people could not get close to the radiator due to hot or cold airflow, but by installing this equipment, the room can be used widely and the layout of the room becomes free. (9) Since it can be applied to fluids, it can be applied to gases and liquids. It can be applied not only to cold airflow but also to hot ascending airflow. And the like.
