Description

[0001] The present invention relates to an absorptive panel unit controllable angle

The present invention relates to a light absorbing plate unit, and more particularly, to a light absorbing plate unit capable of adjusting the angle of incidence, Absorbing plate unit.

There is a problem that the demand for cooling energy due to global warming increases rapidly and the cooling load is increased due to an increase of the area ratio of windows in buildings. To solve this problem, several functional windows have been studied. The SHGC (Solar Energy Acquisition Rate) of the functional window is used as an indicator of the cooling / heating energy performance of the window, and various measuring devices have been developed to accurately and quickly measure it.

In general, SHGC is derived by measuring the amount of heat absorbed by the absorbing plate after the light irradiated from an artificial or natural light source passes through the specimen. However, the artificial light source is fixed, and the natural light source can not arbitrarily adjust the position of the light source. In other words, the altitude and azimuth angle of the sun changes instantaneously, and the incidence angle of sunlight differs according to the time. Therefore, it is necessary to reflect both altitude and azimuth of the sun.

Patent Document 1 discloses a patented invention pre-registered by the applicant of the present invention. In the general outside environment, the heat input through a building envelope or a window by natural light is measured to measure and calculate thermal performance and quadrature acquisition coefficient of a window or a building envelope A calorimeter for measuring a quadrature acquisition coefficient of a window is disclosed.

The calorimeter for measurement according to the present invention is configured to be mounted on a solar tracking device so as to change an azimuth angle and altitude angle in order to maximize an inflowing solar radiation amount in accordance with the altitude of the sun.

However, in order to adjust the azimuth angle and the altitude angle of the calorimeter, the solar tracking device described above is still an effective invention. However, in order to adjust the azimuth and elevation angle of the calorimeter, an anchor installed on the base of the ground, A mounting bracket integrally fixed to the rotary plate; a first motor fixed to the mounting bracket; and a second motor fixed to the mounting bracket, wherein the rotary driving force of the first motor is transmitted to the rotary plate, An azimuth driving unit configured to rotate the rotating plate through the first motor driving to adjust an azimuth angle; A fixing frame having one end fixed to the mounting bracket and the other end calibrated for rotation by the joint, a rail fixed to the mounting bracket, a movable member capable of horizontally moving on the rail, A screw feeder threadedly engaged with saddles formed on the lower side of the movable member, a second motor connected to drive the screw feeder, and a second end fixed to the lower end of the measuring calorimeter, An altitude angle drive means for adjusting an altitude angle of the calorimeter for measurement by including an actuator; , It is possible to control the inclination angle of the calorimeter according to the altitude and the azimuth of the sun. However, the structure of the adjustment mechanism is very complicated, requiring a lot of parts, requiring a lot of assembly time and installation cost, Is varied according to time and season. Therefore, in order to derive experimental data for each situation, there is a problem that it is necessary to repeat experiment several times by changing experimental conditions in each case. In addition, when the heat absorbed by the heat absorbing plate is absorbed, it is recovered through the heat medium to measure the amount of heat. After the heat medium is cooled again, it takes time from returning to the initial temperature and recirculating the heat medium. It is impossible to accurately match the conditions of the environmental chambers of all the measuring apparatuses, so that accurate experimental data can not be derived.

On the other hand, the heat quantity collecting device of Patent Document 2 suggests a method of shortening the waiting time by cooling the superheated heat quantity sensor with the cooling water, but does not provide a fundamental solution.

Also, in the case of absorbing the heat energy of the absorption plate through the cooling water and estimating the amount of solar heat obtained through the temperature change of the cooling water, in the case of a configuration in which the flow path through which the cooling water flows in contact with the absorption plate is simply laminated, There is a problem that the measurement value may be inaccurate.

The first frame 210 is connected to the respective light absorbing plates A by the rotating shaft members 220 and 230 and the two shaft members are connected to the light absorbing plate A A so that the light absorption plate A can rotate along an imaginary axis passing through the center of gravity of the light absorption plate A. Accordingly, the light absorption plate A can be rotated in the left and right directions with the rotation axis members 220 and 230 placed in the vertical direction as the center points. The rotary shaft members 220 and 230 are of a known configuration and comprise a rotary shaft and a bearing for rotatably supporting the rotary shaft. The light absorbing plate A may be manually rotated, and the rotating shaft members 220 and 230 may be connected to a known motor so as to rotate automatically.

A cooling plate (not shown in Fig. 1, reference numeral 132 in Fig. 1) is attached to the rear surface of each of the light absorbing plates A1 to A9, and the light absorbing plates A1 to A9 are absorbed Coolant flows to absorb the heat again by heat exchange. It is possible to calculate the amount of heat removed by the cooling plate by measuring the temperature difference between the cooling water flowing into the cooling plate stacked on the back surface of the light absorbing plates A1 to A9 and the cooling water discharged by absorbing the heat, (A1 to A9) can be obtained.

According to the first preferred embodiment of the present invention, the rotation angle of the light absorption plate A is adjusted through the rotation axis members 220 and 230 without changing the position of the artificial light source 101 or the angle at which light is emitted from the light source The angle at which the light is incident can be adjusted.

Accordingly, in consideration of the fact that the angle of incidence of the light is changed as the direction of the sun changes, the solar heat absorption calorie can be obtained when the sun is positioned in a specific orientation. Further, the rotary shaft members 220 and 230 are connected to a known motor The solar heat absorption calorie can be effectively obtained by adjusting the rotation angle of the light absorption plate A in accordance with the traveling path of the sun moving in the same direction.

The first frame 210 and the second frame 240 are connected to each other by the rotating shaft members 250 and 260. The two shaft members rotate about the center of gravity of the first frame 210 The first frame 210 is installed to face the left and right sides of the first frame 210 so that the first frame 210 can rotate along a virtual axis penetrating in the horizontal direction. Therefore, the light absorption plate A can rotate in the forward and backward directions with respect to the vertical plane. The rotary shaft members 250 and 260 are constructed of a rotary shaft and a bearing for rotatably supporting the rotary shaft. The first frame 210 may be manually rotated from the rotation axis members 250 and 260, or may be configured such that the rotation axis members 250 and 260 are connected to a known motor to rotate automatically.

Therefore, considering the angle of incidence of light changes with the change of altitude of sun, when the sun is located at a certain altitude, the heat absorption coefficient of solar heat can be obtained by adjusting the light absorption plate (A) Further, when the rotating shaft members 250 and 260 are connected to a known motor so as to automatically rotate in accordance with the altitude of the sun, the optical absorbing plate A is moved from one end to the other in accordance with the traveling path of the sun, Therefore, the calorific value of solar heat can be obtained.

It is also possible to control the angle of each of the light absorbing plates A1 to A9 by controlling the rotation angles of the respective rotary shaft members 220 and 230 in different ways, Acquired calories can be obtained at once.

4 is a front view showing a third preferred embodiment of the present invention.

The third embodiment is also different from the first embodiment in that it further includes a second frame 240 having a rectangular outer shape and a receiving space in which the first frame 210 is received. The first frame 210 and the second frame 240 are connected to each other by the rotation shaft members 250a and 260a (the suffixes after the reference characters 250 and 260 denote the vertical axis direction) 250a and 260a are arranged on the upper side and the lower side of the first frame 210 so that the first frame 210 can rotate along the imaginary axis in the vertical direction in which the two shaft members pass through the center of gravity of the first frame 210 As shown in Fig. Accordingly, as the first frame rotates in the left and right directions from the rotation axis members 250a and 260a, the entire light absorption plate A can be rotated in the left and right direction at the same time, The left and right rotations of the light absorption plates A1 to A9 through the respective rotation axis members 220 and 230 may be fine-tuned as a whole or individually. The rotary shaft members 250a and 260a are constituted by a rotary shaft and a bearing in a known configuration. The first frame 210 may be manually rotated, and the rotating shaft members 250a and 260a may be connected to a known motor so as to rotate automatically.

Similar effects can be obtained by making the degrees of rotation of the light absorbing plates A1 to A9 the same in the left and right direction in the first embodiment, but in the third embodiment, It is possible to rotate the light absorbing plate A with ease and fine adjustment of the light absorbing plates A1 to A9 as a whole in the same direction or to individually and selectively adjust the light absorbing plates A1 to A9 in opposite directions have.

Particularly, the degree of rotation of each of the light absorbing plates A1 to A9 is changed in the left and right directions, and the light absorbing plates A1 to A9 are collectively rotated using the first frame 210, By applying the time-varying effect, it is possible to measure the amount of heat of solar heat acquired by changing the orientation of the sun with time, starting from different viewpoints.

Fig. 5 is a front view showing a fourth preferred embodiment of the present invention. The basic structure and concept of the fourth embodiment are similar to those of the first embodiment.

In the light absorbing plate unit of the fourth embodiment, a plurality of rectangular light absorbing plates A1 to A9 (A) in the illustrated embodiment are spaced vertically and horizontally, Respectively. The outer frame of the first frame 210 is rectangular and has a receiving space capable of accommodating nine light absorbing plates A one by one by a frame structure forming a grid pattern space therein, ) It encloses each circumference. Each of the light absorbing plates A and the frames are connected by the rotating shaft members 220b and 230b (the suffixes after the reference numerals 220 and 230 hereinafter denote the horizontal axis direction), and the rotating shaft members 220b and 230b Is arranged so as to be opposed to the left and right sides of the light absorbing plate (A) so that the light absorbing plate (A) can rotate along the imaginary axis passing through the center of gravity of the light absorbing plate (A) do. Therefore, the light absorption plate A can be rotated in the forward and backward directions with reference to the vertical plane. The rotary shaft members 220b and 230b are formed of a rotary shaft and a bearing in a known configuration. The light absorbing plate A may be manually rotated and the rotating shaft members 220b and 230b may be automatically rotated by being connected to a known motor.

Cooling plates (not shown in the drawings: see reference numeral 132 in Fig. 1) are attached to the rear surfaces of the respective light absorbing plates A1 to A9, and cooling water flows so as to flow in from one side and discharge to the other side. Since the temperature of the incoming cooling water is increased by the heat absorbed by the light absorbing plates A1 to A9 in the process of being moved to the exhaust side, the temperature difference between the incoming cooling water and the discharged cooling water can be measured to calculate the heat removed by the cooling plate Therefore, it is possible to obtain the solar heat calorific value in each of the light absorbing plates A1 to A9.

According to the fourth preferred embodiment of the present invention, the angle of incidence of light can be adjusted by adjusting the rotation angle of the light absorption plate A without changing the position of the artificial light source 101 or the angle at which the light is emitted from the light source .

Accordingly, taking into consideration that the angle of incidence of light varies with the change of the altitude of the sun, the solar heat absorption calorie can be obtained when the sun is located at a specific altitude. Further, the rotary shaft members 220b and 230b are connected to a known motor , The solar heat acquisition calorie can be obtained in accordance with the moving path of the sun which becomes higher and higher altitude as it moves from one end to the other.

In addition, if the angle of rotation of each of the light absorbing plates (A1 to A9) is different, the heat of solar heat collection at various altitudes can be obtained at one time without repeating a number of experiments.

In addition, the zoning can be performed for example in the case where the left side light absorbing plates A1, A4 and A7, the middle light absorbing plates A2, A5 and A8 and the right side light absorbing plates A3, A6 and A9, If the heat quantity to be obtained is obtained, it is possible to calculate the heat quantity of solar heat acquisition in each part, and efficient cooling and heating facilities according to the zones can be performed based on this.

In the fourth embodiment, it is assumed that the nine light absorbing plates A in a rectangular shape are arranged in three rows horizontally and vertically, with the columns aligned vertically and horizontally, but they are not deviated from the technical scope of the fourth embodiment It is obvious that the shape, arrangement and number of the light absorbing plate A can be freely selected within the limit.

6 is a front view showing a fifth preferred embodiment of the present invention.

The fifth embodiment differs from the fourth embodiment in that it further includes a second frame 240 having a rectangular outer shape and a receiving space in which the first frame 210 is received.

And is disposed to face the left and right sides of the first frame 210 so that the first frame 210 can rotate along a virtual axis passing through the center of gravity. Accordingly, as the first frame 210 rotates in the forward and backward directions from the rotary shaft members 250 and 260, the entire light absorbing plate A can be rotated forward and backward with respect to the vertical plane as a whole, Each of the light absorbing plates A can be individually or wholly rotated in the front and rear direction by the rotation axis members 220b and 230b supporting the first frame 210 in the horizontal direction. The rotating shaft members 250 and 260 are constituted of a rotating shaft and a bearing in a known configuration. The first frame 210 may be manually rotated and the rotation axis members 250 and 260 may be connected to a known motor to rotate automatically. And the rotation direction and the angle of the light absorption plate A can be individually adjusted.

Further, the rotary shaft members 250 and 260 are connected to a known motor It is possible to obtain the heat of solar heat collection according to the movement path of the sun as it moves with respect to each other.

The first frame 210 and the second frame 240 are connected by the rotating shaft members 250a and 260a and the two shaft members are connected to the first frame 210 in the vertical direction. The first frame 210 is installed to face the upper side and the lower side of the first frame 210 so that the first frame 210 can rotate along a virtual axis passing through the center of gravity. Accordingly, as the first frame is rotatable in the left and right directions, the entire light absorbing plate A can be rotated in the left-right direction at a time. The rotary shaft members 250a and 260a are constituted by a rotary shaft and a bearing in a known configuration. The first frame 210 may be manually rotated, and the rotating shaft members 250a and 260a may be connected to a known motor to rotate automatically.

In the first embodiment, similar effects can be obtained by equalizing the degrees of rotation of the light absorbing plates A1 to A9 in the lateral direction. However, in the sixth embodiment, there is an advantage that the light absorbing plates A1 to A9 can be rotated in the lateral direction at a time.

The rotation axes of the respective light absorption plates A1 to A9 are changed in the upward and downward directions by rotating the rotation axis members 220b and 230b installed horizontally and the rotational axis members 250a and 260a are arranged in the vertical direction, When the effect of changing the altitude of the sun with time is applied by rotating the respective light absorbing plates A1 to A9 collectively in the left and right directions using the first frame 210 rotated by the first frame 210, So that the heat of solar heat can be measured by changing the altitude of the sun with time.

The rotary shaft members 220 and 230 are formed of a rotary shaft and a bearing in a known configuration. The light absorbing plate A can be manually rotated and the rotating shaft members 220 and 230 can be automatically rotated by being connected to a known motor.

Accordingly, considering the angle of incidence of the light varies depending on the azimuth and altitude of the sun, the solar heat acquisition calorie can be obtained when the sun is positioned at a specific orientation and altitude, further, the rotation axis members 220, 230, 250, Is connected to a known motor and rotates automatically, the altitude becomes higher as it moves from one end to the other. The solar thermal calorie can be obtained in accordance with the lowering and higher altitude of the sun.

In addition, if the angle of each of the light absorbing plates (A1 to A9) is different, the solar heat absorbing calories at various azimuths and altitudes can be obtained at one time without repeating a number of experiments.

In addition, by dividing the zone (zoning) and obtaining the calorific value of solar heat, it is possible to calculate the calorific value of solar heat from each part, so that it is possible to provide efficient heating /

9 is a front view showing an eighth preferred embodiment of the present invention.

The difference from the seventh embodiment is that the first frame 210a and the light absorbing plate A are connected by the horizontal shaft members 220b and 230b so that the light absorbing plate A can be rotated forward and backward The first frame 210a and the second frame 240a are connected by the vertical shaft members 250a and 260a so that the first frame 210a can rotate in the left and right direction, The absorption plate A rotates in the front, rear, left, and right directions. Therefore, the installation concept and effect of the seventh embodiment are substantially the same only in the arrangement state structure of the rotating shaft members.

10 is a perspective view showing the flow of the cooling plate and the fruit.

The cooling plate includes a heat exchanging part 300 located at the rear surface of the light absorbing plate and having a laminated flow path formed therein, an inflow pipe 310 through which the cooling water flows from the cooler, and a heat absorbing heat absorbed by the light absorbing plate along the flow path. And a discharge pipe 330 for discharging the gas. The inlet pipe 310 and the outlet pipe 330 are provided with a temperature measuring device to measure the temperature difference between the inflow water and the drain water and to derive the heat absorbed from the light absorbing plate by the cooling plate.

Two inlet pipes (310) are installed at both ends of the lowest layer flow path, two discharge pipes (330) are installed in the upper layer flow path, and a plurality of flow paths . Accordingly, the lower-layer flow path is provided with an opening portion through which the cooling water can rise at the center, and the lamination flow path structure in which the openings through which the cooling water can rise can be repeatedly formed in the upper- It flows from both ends of the channel to the central point, then meets at the central point and ascends to the top, flows from the middle point of the upper floor channel to the both ends, and flows repeatedly from the ends to the upper floor channel.

Therefore, as compared with the conventional cooling plate in which a simple laminated flow path is formed, the convection of the cooling water becomes active, a uniform temperature distribution is exhibited in the flow path of the same layer, and a longer time flows in the same volume. Less. As a result, more accurate measurements can be obtained.

Further, since the cooling plate can absorb more heat from the light absorbing plate to promote cooling of the light absorbing plate, the waiting time is shortened when the experiment is repeatedly performed.

While the present invention has been described in connection with what is presently considered to be practical exemplary embodiments, it is to be understood that the invention is not limited to the disclosed embodiments. Therefore, the scope of the present invention should not be construed as being limited to the embodiments described, but should be determined by the scope of the appended claims, as well as equivalents thereof.
