Description

Specification

Solar heat collecting and collecting / exhaust heat equipment and its utilization method

The present invention relates to an apparatus for collecting and exhausting heat while ensuring daylighting while dimming solar heat, and relates to a solar heat collecting and heat collecting apparatus and a method of using the same. Background art

Daylighting and temperature adjustment in the building room is controlled by shading of sunlight, heat insulation, and heat insulation, but so-called shutter-type blinds have conventionally been combined in the form of strips of metal plates in windows. In summer, the blinds are closed manually to shield and shield the light, and the room temperature is adjusted. In winter, it is also opened to collect the light and adjust the room brightness and room temperature. In recent years, external heat insulating materials have been used on the outer wall surfaces of ordinary houses to form a heat insulating wall on the entire surface of the outer wall, excluding the windows, to shield solar heat and to insulate the room. Also, in high-rise buildings where the entire window is covered with glass, a glass coating on the window glass is used to shield and shield the heat from this coating.

In addition, for greenhouses and greenhouses, sunlight is collected by the vinyl or glass covering the surroundings, and when the room temperature drops in the winter, the temperature rises with a heating device such as a heater. The windows are fully open, and light control and temperature control are performed using light-shielding curtains.

Problems to be solved by the invention

The conventional ones do not perform solar light collection and heat insulation, heat collection / exhaustion and heat insulation throughout the year, whether summer or winter. In particular, shutter-type blinds are open in winter and use solar heat indoors in parallel with daylighting in the room. However, in summer, lighting is restricted if the heat is shut down and lighting is limited. It is necessary to ensure lighting by the device. In addition, unnecessary solar heat is collected in the blinds installed indoors, the room temperature rises excessively, and heat shielding and exhaust heat effects are not achieved. The outer heat insulating wall method is used for heat insulation, but is not a method for collecting and exhausting heat.

In addition, greenhouses and greenhouses are also used for indoor heating by solar heat in the cold season, but the indoor temperature rises excessively during the daytime when the solar heat falls in the summer. In order to suppress the temperature rise, it is artificially opened to introduce the outside air, or the shading curtain is used to extinguish and shield the heat so as to prevent the room temperature from rising excessively. No means to ensure exhaust heat at the same time is used.

The present invention is to solve the above-described problems, and is to effectively use the light and heat of the sun through the four seasons. Reflected multiple times, and once incident sunlight and heat are reflected without reflecting in the incident direction, heat is collected to the back of the equipment, and the collected heat energy is temporarily stored. To use Therefore, it is used as a heat source for heating the room, as a heat source for various devices, or by temporarily storing the collected heat energy and exhausting it outside the room, thereby suppressing the temperature rise in the room.

More specifically, it is used for the windows of buildings for the purpose of daylighting, the outer periphery of the greenhouse or greenhouse, and is used for daylighting and heat insulation in the room, for daylighting and heating in the room, or in the building ^^ By using it, heat insulation and heat insulation can be achieved while ensuring the transmission of sunlight. In addition, it is installed near the ceiling of buildings, greenhouses and greenhouses to function as an indoor heat exhaust device and suppress the temperature rise in the room.

Means for solving the problem

In a heat-insulated storage box fitted with a front heat insulation cover on the front, a plurality of sheet heat collecting plates with a plurality of reflective heat collecting chambers that receive solar heat and repeat heat reception and reflection are built-in. The heat collected by the heat plate is stored in a single heat storage chamber via each heat conduction section, and is connected to external equipment through a heat transfer pipe connected to the heat storage chamber for heat utilization and exhaust heat, or The heat transfer pipe is introduced into the building for heat utilization, while sunlight reflected by the planar heat collecting plate and dimmed can be transmitted through the rear heat insulation cover provided on the rear surface of the heat insulation storage box. It is daylighted indoors. It is also used as an external heat insulating material by using it on the outer wall of the building.

In addition, it is possible to suppress overheating by using heat collection in greenhouses and greenhouses, as well as daylighting, heat shielding and exhaust heat in Biernouss and greenhouses.

The invention's effect

As a solar heat energy collecting method, according to the planar heat collecting plate described above, even if the shape of the solar heat collecting and collecting and exhausting heat device is flat, concave, or convex depending on the installation location, the sunrise From daylight to sunset, it is possible to collect light and collect heat without fixing or correcting the incident angle. In addition, once the solar heat is incident on the reflective heat collection chamber, it is not reflected on the incident side, so after the solar heat that has passed through the glass of the front heat insulation cover, heat insulation storage with high heat insulation performance that does not cause heat loss Heat is collected by the planar heat collecting plate provided inside the box, and the upper heat storage chamber can collect heat at a higher temperature.After taking the heat energy of solar heat, only the sunlight is taken. Since it is possible to use the rear heat insulation cover to suppress the temperature from becoming high, sunlight and heat energy can be separated and used to ensure indoor heat insulation, heat insulation, and lighting in the summer. On the other hand, lighting and heat collection are possible in winter.

By using the solar heat focusing device of the present invention, the solar light that is radiated by the solar heat is collected in the reflection heat collection chamber without any loss by repeating the reflection of the solar radiation, and the reverse reflection in the solar radiation direction is Since there is no such thing, solar heat can be used efficiently.

The collected heat is introduced into the room in the winter by a heat transfer pipe such as a heat-insulated pipe and used as a heating source, and in the summer the heat transfer pipe is connected to an external device such as a hot water storage tank. It can be used as a heat source.

In addition, sunlight that can be used as a heat insulating wall that can be daylighted in the window, and after being repeatedly reflected in the reflective heat collection chamber, is irradiated with soft light throughout the room as dispersed light. Irradiation of only a part of the room due to high temperature direct light from it can be eliminated.

From the above, the heat transfer pipe of the device of the present invention can be used on the roof of the building shown in Fig. 5 as shown on the left side of the figure, and it is optimal for winter use. Do Therefore, it is ideal for use in the summer, and the heat transfer pipe can be used in combination with the left and right sides, not to mention in summer and winter, but also to adapt to seasons other than summer and winter.

Also, as shown in Fig. 6, when it is necessary to daylight indoors of the building, it can be used only for windows, and it can also be used for greenhouses or greenhouses as shown in Fig. 7. You can also use a combination of the left side and the right side.

8 and 9 can suppress the high temperature in the greenhouse of a greenhouse, greenhouse, or building by exhaust heat, and can function as indoor ventilation.

With the device of the present invention, solar thermal energy that passes through a window or the like and falls into the room is separated into sunlight and solar thermal energy, and the separated solar light is collected indoors as dispersed light, and the separated solar thermal energy is It collects heat and is used as a heat source for other equipment, and it is also used for indoor heating.

Example 1

Figure 1 shows a glass that prevents sunlight from entering the front of the solar light collection and collection / exhaust heat collector, that is, the side where sunlight enters, as much as possible while preventing heat radiation from the inside as much as possible. A front thermal insulation cover (3) using a board or synthetic resin such as acrylic or polycarbonate with transparency is provided, and a rear thermal insulation bar (9) having the same characteristics as the front thermal insulation cover (3) is provided on the rear surface. Provide different sizes between the front and rear heat insulation covers (3, 9), that is, the opening height and thickness of the reflective heat collection chamber are made smaller as the front increases and the rear increases. In order This is a heat insulation storage box (1) that has a built-in planar heat collecting plate (2) that spreads in the shape of the sunlight that collects and collects incident solar heat. A heat converging part (4) that focuses the heat of the planar heat collecting plate (2) is provided in contact with the upper part of each of the planar heat collecting plates (2), and is provided above the heat converging part (4). A heat storage chamber (6) is provided through the heat conduction part (5) to temporarily store heat.

Next, the heat energy stored in the heat storage chamber (6) is transferred to the outside or the room via a heat transfer pipe (8) such as a heat-insulated coated metal or non-ferrous metal pipe connected to the heat storage chamber (6). Heat transfer to

FIG. 1 is a front view of the device according to the present invention. The heat insulating storage box (1) has a box shape and has a heat insulating structure. The shape can be triangular, polygonal, circular, semi-circular, etc. in addition to a box shape.

In the direction in which solar heat is radiated, that is, in the right direction in Fig. 2, a front heat insulating cover (3) made of a synthetic resin such as a glass plate or transparent acrylic or polycarbonate that allows the transmission of solar heat is insulated. The storage box (1) is installed in a sealed state. A multilayer heat collecting plate (2) is provided inside the heat insulation storage box (1), and is fixedly mounted in the heat insulation storage box (1).

The planar heat collecting plate (2) is composed of multiple layers of planar heat collecting plate members (2A) (2B) (2C) force with the same external shape. Each member (2A-2C) Is a hexagonal honeycomb structure, and is a metal or non-metallic material that reflects sunlight and is capable of receiving heat, specifically an aluminum material or an aluminum foil. Also, as shown in Fig. 4, the opening height (Hl, H2, H3) of the reflective heat collecting chamber (U, V, W) of the hexagonal honeycomb structure of each planar heat collecting plate member (2A-2C) The thickness (Tl, Τ2, Τ3) also decreases gradually as you go from Τ1 to Τ3, and the surface from the front insulation cover (3) side The heat collecting plate members (2A, 2B, 2C) are stacked in this order.

A heat converging part (4) made of the same material as the surface heat collecting plate (2) is in close contact with the upper surface of the sheet heat collecting plate (2). A box-shaped heat storage chamber (6) is in contact with the upper part of (4) via the heat conduction part (5).

A heat transfer pipe (8) is connected to the heat storage chamber (6), and it protrudes outside the heat insulation storage box (1) for convenient connection with external equipment. ) It is covered with a heat insulating material (7) on the outside. In addition, the connection between the heat transfer pipe (8) and the heat insulating storage box (1) is also considered to be a heat sink.

In addition, the rear heat insulation cover (9) is the same position as the front heat insulation cover (3) at the position facing the front heat insulation cover (3) and on the rear side of the planar heat collecting plate (2). It is installed in a state that keeps the heat inside the heat insulation storage box (1).

The heat conduction part (5) in contact with the heat storage chamber (6) is placed opposite to the heat transfer pipe (8), and the heat collected in the heat converging part (4) It is stored in the heat storage chamber (6) via the heat conduction part (5). Heat from the heat storage chamber (6) is prevented from flowing back to the heat collecting plate (2) and stably supplied to the heat transfer pipe (8) in the shade and at night due to clouds with reduced solar radiation. For this purpose, the volume of the heat storage chamber (6) is made as large as possible, and at the same time, the heat conduction part (5) is arranged in the opposite direction not close to the heat transfer pipe (8). It should be noted that the solar heat collecting and collecting / exhausting heat apparatus according to the present invention is installed above the ground, the front heat insulating cover (3) side is the side receiving the solar radiation, and the heat transfer pipe (8) is the upper side. In addition, the sun's height and solar radiation angle change according to the four seasons, so it can be moved in response to the changes.

Next, the operation of the present invention will be described.

Fig. 3 and Fig. 4 show a state in which solar heat is radiated to the solar heat collecting and collecting / exhausting heat device of the present invention. The front heat collecting cover (3) is passed through the planar heat collecting plate (2). The solar heat (a) is shown by two light traces for convenience in the state where the solar heat is radiated in the reflection heat collecting chamber (U) of the planar heat collecting plate member (2A).

The solar heat (a) is transmitted through the front insulation cover (3), radiates to the lower surface of the reflective heat collecting chamber (U) with sunlight, and is reflected at the reflection angle / 3. At this time, the incident point (P 1) and the reflection point (P2) reflect the solar photothermal energy and receive heat by radiation, and if the solar heat continues to be radiated continuously, the reflected heat collection chamber (U ) The inside is heated and stored, and as time passes, it conducts heat to the reflective heat collection chamber (U) located on the upper floor, and finally it is focused on the heat focusing section (4) .

Since the planar heat collecting plate (2) of the present invention is laminated in the order of the planar heat collecting plate members (2A) (2B) (2C) as shown in FIG. 4, the planar heat collecting plate members (2 The solar heat radiated into the reflective heat collecting chamber (U) of A) enters the reflective heat collecting chamber (V) of the planar heat collecting plate member (2B), and the solar heat is reflected at the reflecting point (P 2). The energy is received by radiation, and the received heat is focused on the heat focusing section (4) in the same manner as the planar heat collecting plate member (2 A).

Similarly, as shown in Fig. 4, the planar heat collecting plate member (2B) is incident on the planar heat collecting plate member (2 C) and reflected at the reflection point (P3). 4) The heat is focused on. At this time, the thermal energy radiated by the planar heat collecting plate member (2A) is attenuated when reaching the planar heat collecting plate member (2C).

Thus, the heat energy collected by the planar heat collecting plate members (2A), (2B), and (2C) is conducted to the heat converging section (4) and is provided above the heat converging section (4). Heat is stored in the heat storage chamber (6) through the heat conduction section (5).

Therefore, the heat energy stored in the heat storage chamber (6) is introduced into the heat transfer pipe (8) covered with the heat insulating material (7) without any heat loss, and the heat transfer pipe (8) is passed through the heat transfer pipe (8). It can be introduced indoors to raise the temperature inside the room, and can be used as a heat source for various equipment by connecting external equipment outside the room.

Here, the reason why the planar heat collecting plate (2) shown in FIG. 2 is formed into a plurality of layers like the planar heat collecting plate members (2A), (2B), and (2C) is simply the planar heat collecting plate. If only the plate member (2A) is used alone and the planar heat collecting plate member (2A) is a planar heat collecting plate (2) with a thickness T 1 expanded to T, then in the case of T, the solar radiation Light heat repeats regularly, and the reflected light and heat reach the back, but in this state, the number of reflections is small, so a considerable amount of light and heat energy is behind the heat insulation storage box (1) rear heat insulation cover When (9) is reached and passed, the heat collection due to radiation is small, and it cannot be said that solar heat can be effectively used by separating it into sunlight and solar heat energy.

In order to increase the number of reflections of solar heat incident on the planar heat collecting plate (2), The thickness of the heat collection chamber (U, V, W) of the hot plate member (2 A) (2 B) (2 C) is set to T1 to T3, the height is set to HI to 暫 3, and it is reduced for a while. Can be realized. As shown in Fig. 4, after the solar heat is incident, the incident and reflection are repeated more frequently until the planar heat collecting plate member (2C) located at the rear reaches the reflection heat collecting chamber (U, V, W) receives a considerable amount of heat energy due to the heat received during incident and reflection, so that the heat energy received by the planar heat collecting plate members (2A) (2 B) (2 C) has a significant heat collecting effect. Raised. Therefore, each solar thermal energy reaching the planar heat collecting plate member (2C) is attenuated, and there is almost no reflection toward the front which is the incident direction, and it is almost non-reflective, and the rear heat insulating cover (9 Because the solar photothermal energy that passes through the surface is also attenuated, much of the solar projection energy is applied to the upper part of the planar heat collecting plate members (2A), (2B), and (2C) and to the heat converging part (4) by thermal convection. It will be in a heated state. The thermal energy heated by the heat converging part (4) is stored in the heat storage chamber (6) through the heat conduction part (5) by heat convection. At this time, since the heat insulating storage box (1) has a heat insulating structure, the heat storage energy in the heat storage chamber (6) is retained.

On the other hand, light energy can be transmitted through the rear heat insulation cover (9) that is dimmed by being incident or reflected by the planar heat collecting plate members (2A, 2B, 2C).

Also, as shown in Fig. 4, the light energy reflected by the planar heat collecting plate member (2C) in the heat insulating storage box (1) Since the amount of light is scattered upward as in the case of dispersed light, the light is transmitted through the rear thermal insulation cover (9) in a dimmed state, and is also dispersed vertically and horizontally (up and down in the figure). It is emitted to the outside of the heat insulation storage box (1). Therefore, in the current window structure that does not use the device of the present invention, direct sunlight is incident, so that the incident light is concentrated and incident only on a part of the room as direct light that is not dispersed. The temperature rises and it becomes necessary to shield the light with a blind.

The example shown in Fig. 5 shows an example in which the building is used as a roof and an outer wall of a building as an outer heat insulating wall, and can also be used for collecting heat in the room. The collected heat energy can also be used via a heat storage device such as a hot water storage tank. In this case, the heat insulation storage box (1) does not use the rear heat insulation cover (9), but increases the number of sheet heat collecting plate members of the heat insulation storage box so that the rear heat insulation cover is omitted. You may use what made the structure which blocks permeation | transmission.

Fig. 6 is used for heat insulation of windows and heat collection in the room, and also enables daylighting. In this case, as described in FIG. 4, the solar heat is a planar heat collecting plate member.

Thermal energy is attenuated by repeating incidence and reflection at (2A, 2B, 2 C), but since heat is already stored in the heat storage chamber (6) and the light energy decreases at the same time, the device of the present invention is installed in the window. Even if it is covered as a whole, daylighting is ensured, and when it acts as a moderate blind, it can simultaneously exhibit the effect of heat insulation of the window and heat collection in the room. In this case, when the light energy transmitted through the rear heat insulating cover (9) is large, the amount of transmitted light can be suppressed by using a filter or the like for the rear heat insulating cover (9).

In addition, although this invention apparatus is protruded and installed from the window part, you may install this invention apparatus directly instead of the conventional window glass.

As shown in FIG. 7, the present apparatus is used in a greenhouse and in a greenhouse. Similar to the use of the window in Fig. 6, it is possible to suppress the temperature by collecting and insulating the heat while ensuring the daylighting, and it is possible to suppress the high temperature in the greenhouse and greenhouse. The collected heat energy can be used for heat energy via a heat storage device such as a hot water storage tank at night when solar heat does not reach.

The one shown in Fig. 8 is installed near the ceiling in the greenhouse, and the one shown in Fig. 9 is installed near the ceiling of the building, and the thermal energy of solar heat irradiated on the present invention device is used for the vinyl house. High temperature is suppressed by heat transfer to the outside of the building or outside the building, and the high temperature existing in the plastic house or the upper layer of the building is exhausted. In addition, if external equipment is installed outside the vinyl house or outside the building, this waste heat can be used as a heat source for external equipment. At this time, the heat transfer pipe (8) may be installed on the side of the planar heat collecting plate member (2A) opposite to the position in FIG.

As shown in Fig. 6, the heat transfer pipe (8) is one indoor and the other is outdoor. Therefore, the heat transfer pipe (outdoor) in Figs. When combined, it functions in the same way as in Fig. 6, so in the examples in Fig. 5 to Fig. 7, it functions as a heat transfer pipe to the room in winter and as a heat transfer pipe to the outside in summer. It can be used as open or closed as appropriate.
