[0027] The above drawings have shown clear embodiments of the present application, which will be described in more detail later. These drawings and text descriptions are not intended to limit the scope of the present application in any way, but to illustrate the concept of the present application to those skilled in the art by referring to specific embodiments. DETAILED DESCRIPTION

[0028] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the following exemplary embodiments do not represent all implementations consistent with the present application. Instead, they are merely examples of devices and methods consistent with some aspects of the present application as detailed in the appended claims.

[0029] First, the terms involved in this application are explained:

[0030] Shutters: refers to a window composed of multiple blades arranged in an arrangement, which is used to open and close the window and adjust the light transmittance. The blades can be made of glass, plastic or metal, and the blades can be transparent, translucent or opaque.

[0031] Low-E coating layer: refers to a multi-layer metal or compound film coated on the surface of an object, which is mainly used to reduce the radiation energy of the surface of the object, thereby improving its thermal insulation and heat preservation performance. The main components of the Low-E coating layer include silver, copper, tin and other metals or other compounds. By forming one or more layers of thin film on the surface of the glass, the emissivity of the glass is significantly reduced, thereby reducing the transfer of radiation heat.

[0032] High emissivity coating layer: refers to a thin film coated on the surface of an object, whose main function is to increase the object's ability to emit infrared radiation. This coating layer is usually used in thermal control materials to achieve better thermal radiation effects.

[0033] Electrochromism (EC) film: refers to a film whose color changes reversibly under the action of an external electric field. It can be attached to the blades of blinds to adjust the light transmittance. There are two types of electrochromic materials. One is inorganic electrochromic materials, whose light absorption changes are caused by the dual injection / extraction of ions and electrons, and whose performance is superior and stable; the other is organic electrochromic materials, whose light absorption changes come from redox reactions, rich colors, and easy molecular design. Organic electrochromic materials include transition metal oxides, which can be divided into reduction process cathode coloring materials (such as W, Mo, V, Nb and Ti oxides) and oxidation process anode coloring materials (such as Ir, Rh, Ni, and Co oxides) according to the coloring method. Among them, WO3 is the most widely used cathode coloring electrochromic material.

[0034] Figure 1 A schematic diagram of a scenario of a method for controlling blinds in a computer room provided in this application, such as Figure 1 As shown, the specific application scenarios of the present application include a computer room and shutters for a computer room. The shutters for a computer room are installed in the wall of the computer room, and include a first shutter portion and a second shutter portion arranged in parallel, and a control component. The control component obtains the indoor temperature value measured by a temperature sensor; if the indoor temperature value is less than a first temperature threshold, the working mode of the shutters for the computer room is determined to be a heat preservation mode; if the indoor temperature value is greater than a second temperature threshold, the working mode of the shutters for the computer room is determined to be a heat dissipation mode, and the second temperature threshold is greater than or equal to the first temperature threshold; based on the determined working mode, the shutters for the computer room are adjusted according to the relationship between the indoor temperature value and the outdoor temperature value.

[0035] Combined with the above scenario, it can be seen that in the prior art, as part of the building's outer enclosure, the exterior windows play a role in creating a good indoor environment such as lighting and ventilation. However, from the perspective of heat transfer, windows are often a large part of the cold and heat load in the building envelope due to their own structural reasons. For example, in summer, the combined solar transmittance and the heat conduction and convection heat transfer of indoor and outdoor air often account for a large part of the indoor cold load. Therefore, how to reduce the energy consumption of the air conditioning cold and heat load in the computer room through the exterior windows is an urgent problem to be solved.

[0036] The blinds control method for a computer room provided in the present application obtains the indoor temperature value measured by a temperature sensor;

[0037] If the indoor temperature value is less than the first temperature threshold, the working mode of the blinds for the computer room is determined to be the heat preservation mode; if the indoor temperature value is greater than the second temperature threshold, the working mode of the blinds for the computer room is determined to be the heat dissipation mode, and the second temperature threshold is greater than or equal to the first temperature threshold;

[0038] Based on the determined working mode, the technical means of adjusting the blinds of the computer room according to the relationship between the indoor temperature value and the outdoor temperature value achieves the technical goal of reducing the energy consumption of the cooling and heating loads of the air conditioner in the computer room.

[0039] The technical solution of the present application and how the technical solution of the present application solves the above-mentioned technical problems are described in detail below with specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present application will be described below in conjunction with the accompanying drawings.

[0040] Figure 2 Schematic diagram of the structure of the machine room shutter provided for this application Figure 1 , Figure 3 Schematic diagram of the structure of the machine room shutter provided for this application Figure 2 ,like Figure 2 , 3 As shown, the machine room shutter 100 comprises:

[0041] A first louver portion 110 and a second louver portion 120 arranged in parallel, and a control component 130;

[0042] The first louver portion 110 is located at the outdoor side of the machine room louver 100, and the first louver portion 110 includes a first low emissivity surface 111 and a first high emissivity surface 112;

[0043] The second louver portion 120 is located at the indoor side of the machine room louver 100 , and the second louver portion 120 includes a second low emissivity surface 121 and a second high emissivity surface 122 ;

[0044] The first low emissivity surface 111 and the second low emissivity surface 121 are provided with a low emissivity coating layer, and the first high emissivity surface 112 and the second high emissivity surface 122 are provided with a high emissivity coating layer;

[0045] The control component 130 is used to control the blades 113 of the first louver portion 110 and the blades 113 of the second louver portion 120 to rotate.

[0046] In the present application, the blades 113 of the first louver portion 110 are controlled to rotate by the control component 130, so that the first low emissivity surface 111 and the first high emissivity surface 112 on both sides of the first louver portion 110 can alternately face the outdoors according to the situation, thereby adjusting the amount of outdoor heat radiation entering the indoor space. For example, in hot summer weather, the shutters 100 for the computer room need to achieve heat insulation, so the first low emissivity surface 111 of the first louver portion 110 is turned to the outdoor side, and the outdoor heat radiation is reflected by the low emissivity coating layer on the first low emissivity surface 111 to prevent heat radiation from entering the indoor space.

[0047] The blades 113 of the second louver portion 120 are controlled to rotate by the control component 130, so that the second low emissivity surfaces 121 and the second high emissivity surfaces 122 on both sides of the second louver portion 120 can alternately face the interior according to the indoor conditions, thereby adjusting the amount of indoor heat radiation transmitted to the outdoors. For example, in cold winter weather, the shutters 100 for the machine room need to achieve the effect of heat preservation, so the second low emissivity surface 121 of the second louver portion 120 is turned to the indoor side, and the indoor heat radiation is reflected by the low emissivity coating layer on the second low emissivity surface 121 to prevent the heat radiation from being transmitted to the outdoors.

[0048] Furthermore, in order to improve the heat dissipation or heat preservation effect of the machine room shutter 100, the control component 130 may control the blades 113 of the first shutter portion 110 and the blades 113 of the second shutter portion 120 to rotate jointly under different circumstances.

[0049] Specifically, the control component 130 includes a motor 131, a transmission chain 132, a transmission rod 133 and a rotating shutter fixing bearing 134;

[0050] The motor 131 is connected to the transmission chain 132, the transmission chain 132 is connected to the transmission rod 133, the transmission rod 133 is connected to the blades 113 of the first louver part 110 and the second louver part 120, and the motor 131 drives the blades 113 of the first louver part 110 and the blades 113 of the second louver part 120 to rotate;

[0051] The rotating louver fixing bearing 134 is used to fix both sides of each blade 113 in the first louver section 110 and the second louver section 120 .

[0052] Particularly, the blades 113 and the transmission chain 132 may be connected via a transmission gear 137 , and the rotation of the transmission chain 132 drives the blades 113 to rotate.

[0053] Specifically, the control component 130 further includes a temperature sensor 135 , and the temperature sensor 135 is used to measure an outdoor temperature value, an indoor temperature value, and a cavity temperature value between the first louver portion 110 and the second louver portion 120 .

[0054] Specifically, the control component 130 further includes:

[0055] Light sensor 136, light sensor 136 is used to measure outdoor light value and indoor light value;

[0056] And / or, an electrochromic film, the electrochromic film is arranged between the low emissivity coating layer and the blades in the first low emissivity surface, or between the high emissivity coating layer and the blades in the first high emissivity surface.

[0057] For example, an electrochromic film can be first attached to one side of the blades of the first louver part, and then a low-emissivity coating layer and a high-emissivity coating layer are attached respectively, so that the electrochromic film is located between the low-emissivity coating layer and the high-emissivity coating layer, thereby adjusting the transmittance.

[0058] Figure 4 Schematic diagram of the process of controlling the machine room blinds 100 provided in this application Figure 1 ,like Figure 4 As shown, the method includes:

[0059] S401. Obtain an indoor temperature value measured by a temperature sensor.

[0060] S402: If the indoor temperature value is less than a first temperature threshold, determine that the working mode of the computer room blinds is a heat preservation mode.

[0061] S403: If the indoor temperature value is greater than a second temperature threshold, determine that the working mode of the computer room blinds is a heat dissipation mode, and the second temperature threshold is greater than or equal to the first temperature threshold.

[0062] S404: Based on the determined working mode, according to the magnitude relationship between the indoor temperature value and the outdoor temperature value, the blinds for the computer room are adjusted.

[0063] In the present application, the working mode of the computer room blinds 100 is first determined by the magnitude relationship between the indoor temperature value and the first temperature threshold and the second temperature threshold, wherein the first temperature threshold is less than or equal to the second temperature threshold, and the first temperature threshold and the second temperature threshold can be determined according to the temperature suitable for the equipment in the computer room to operate, for example, the first temperature threshold can be set to 18 degrees Celsius and the second temperature threshold can be set to 26 degrees Celsius. After determining the working mode, the computer room blinds 100 are adjusted according to the magnitude relationship between the indoor temperature value and the outdoor temperature value, so as to achieve the purpose of heat dissipation or heat preservation of the computer room blinds 100 and reduce the energy consumption of the cooling and heating load of the computer room air conditioner.

[0064] Specifically, when the working mode is the heat dissipation mode, adjusting the computer room blinds 100 according to the magnitude relationship between the indoor temperature value and the outdoor temperature value may include:

[0065] If the outdoor temperature value is lower than the indoor temperature value, the blades 113 of the first louver section 110 are controlled to rotate so that an opening is formed between any adjacent blades 113 of the first louver section 110 , and the blades 113 of the second louver section 120 are controlled to rotate so that an opening is formed between any adjacent blades 113 of the second louver section 120 .

[0066] In the present application, when the working mode is the heat dissipation mode, it means that the temperature of the machine room is high and heat dissipation is required. At this time, if the outdoor temperature value is lower than the indoor temperature value, the shutter 100 can be opened to cool the room with the cooler outdoor air. Therefore, the control component 130 controls the first louver 110 to form an opening between any adjacent blades 113, and controls the blades 113 of the second louver 120 to rotate so that an opening is formed between any adjacent blades 113 of the second louver 120 to achieve the purpose of heat dissipation. In particular, the blades 113 of the first louver 110 and the second louver 120 can be fully opened or only partially opened, and the present application does not limit this.

[0067] For example, Figure 5 The structure of the heat dissipation mode of the blinds for the computer room provided in this application is shown as follows Figure 1 ,like Figure 5 As shown, the first high emissivity surface 112 of the first louver 110 of the room louver 100 is turned toward the outdoor direction, which is conducive to strengthening the radiation heat exchange between the first louver 110 and the outdoor low-temperature airflow. The blades 113 at the upper and lower ends of the first louver 110 are rotated and tilted to form a vent, so that the airflow flows in from the lower end of the first louver 110 and flows out from the upper end, taking away the hot air of the cavity 140 between the first louver 110 and the second louver 120. The second high emissivity surface 122 of the second louver 120 is turned toward the indoor direction, which is conducive to strengthening the radiation heat exchange between the second louver 120 and the indoor relatively high-temperature airflow, transferring the indoor radiant heat to the cavity 140, and the blades 113 at the lower end of the second louver 120 are rotated and tilted to form a vent, so that the colder air outside enters the room from the vent, reducing the indoor temperature. For example, this operating condition occurs on summer nights. Under this condition, the outdoor temperature is low, while the indoor temperature of the computer room is higher than the outdoor temperature due to factors such as heat dissipation of electrical equipment and personnel. Under this condition, the main consideration is to utilize outdoor cold sources as much as possible.

[0068] Specifically, when the working mode is the heat dissipation mode, adjusting the computer room blinds 100 according to the magnitude relationship between the indoor temperature value and the outdoor temperature value may include:

[0069] If the outdoor temperature value is greater than the indoor temperature value, it is determined whether the cavity temperature value corresponding to the cavity 140 between the first louver portion 110 and the second louver portion 120 is greater than the outdoor temperature value;

[0070] If the cavity temperature value is greater than the outdoor temperature value, the blades 113 of the first louver portion 110 are controlled to rotate so that an opening is formed between any adjacent blades 113 of the first louver portion 110, and the blades 113 of the second louver portion 120 are controlled to rotate so that the second high emissivity surface 122 turns toward the indoor direction;

[0071] If the cavity temperature is lower than the outdoor temperature, the blades 113 of the first louver 110 are controlled to rotate so that the first low emissivity surface 111 is turned toward the outdoors, and the blades 113 of the second louver 120 are controlled to rotate so that the second high emissivity surface 122 is turned toward the indoors.

[0072] In the present application, if the outdoor temperature value is greater than the indoor temperature value, the temperature of the cavity 140 may be greater than the outdoor temperature, making the indoor temperature higher. Therefore, the outdoor temperature value and the cavity temperature value are compared. If the cavity temperature value is greater than the outdoor temperature value, the blades 113 of the first louver portion 110 need to be opened to form an opening to allow outdoor airflow to enter the cavity 140 and take away the high-temperature airflow of the cavity 140. The blades 113 of the second louver portion 120 are then rotated to turn the second high emissivity surface 122 toward the indoor direction, so that the indoor radiant heat is transferred to the cavity 140, while the radiant heat of the cavity 140 is not transferred to the indoor. If the cavity temperature value is lower than the outdoor temperature value, the blades 113 of the first louver part 110 are controlled to rotate so that the first low emissivity surface 111 turns toward the outdoors, and the blades 113 of the second louver part 120 are controlled to rotate so that the second high emissivity surface 122 turns toward the indoors, thereby increasing the reflection of outdoor radiant heat through the first low emissivity surface 111 and the second low emissivity surface 121 and reducing the transfer of outdoor radiant heat.

[0073] For example, Figure 6 The structure of the heat dissipation mode of the blinds 100 for the computer room provided in this application is shown in FIG. Figure 2 ,like Figure 6As shown, the first low emissivity surface 111 of the first louver 110 of the machine room louver 100 is turned toward the outdoor direction, which is conducive to increasing the reflection of the first louver 110 on the radiant heat of the higher outdoor temperature. The blades 113 at the upper and lower ends of the first louver 110 are rotated and tilted to form a vent, so that the airflow flows in from the lower end of the first louver 110 and flows out from the upper end, taking away the hot air of the cavity 140 between the first louver 110 and the second louver 120. The second high emissivity surface 122 of the second louver 120 is turned toward the indoor direction, which is conducive to strengthening the transfer of radiant heat between the second louver 120 and the indoor room, and transferring the radiant heat in the room to the cavity 140. At the same time, the radiant heat from the first louver 110 can also be reflected by the second low emissivity surface 121, so that less radiant heat is transferred to the machine room 150. For example, at noon when the sun is shining brightly in summer, since the temperature of the interlayer is higher than the outdoor temperature, more heat enters the room through heat conduction. At this time, the upper and lower shutters of the first louver section 110 are opened, and the ventilation purpose is achieved by adjusting the shutters, so that the heat in the cavity is transferred to the outdoors. At this time, the outdoor air density is relatively large compared to the cavity. Based on the chimney effect, the outdoor air with higher density enters the cavity, mixes with the hotter gas inside the cavity, and is heated by the first louver section 110, so that the density decreases and floats up, and flows to the outdoors through the upper vents of the first louver section 110, completing the cooling of the cavity.

[0074] In particular, the air flow can be accelerated by an axial flow fan. When the cavity temperature is greater than a preset temperature, the axial flow fan is turned on to enhance air flow and quickly cool down.

[0075] Figure 7 The structure of the heat dissipation mode of the blinds 100 for the computer room provided in this application is shown in FIG. Figure 3 ,like Figure 7 As shown, the first low emissivity surface 111 of the first louver portion 110 of the machine room shutter 100 is turned toward the outdoors, which is beneficial to increase the reflection of the first louver portion 110 of the radiant heat of the higher outdoor temperature, and the second high emissivity surface 122 of the second louver portion 120 is turned toward the indoor direction, which is beneficial to strengthen the transfer of radiant heat between the second louver portion 120 and the indoor room, and transfer the radiant heat in the indoor room to the cavity 140.

[0076] In some embodiments, when the working mode is the heat preservation mode, adjusting the machine room blinds 100 according to the magnitude relationship between the indoor temperature value and the outdoor temperature value may include:

[0077] If the outdoor temperature value is lower than the cavity temperature value corresponding to the cavity 140 between the first louver portion 110 and the second louver portion 120, and the cavity temperature value is lower than the indoor temperature value, the blades 113 of the first louver portion 110 are controlled to rotate so that the first low emissivity surface 111 is turned toward the outdoor direction, and the blades 113 of the second louver portion 120 are controlled to rotate so that the second low emissivity surface 121 is turned toward the indoor direction;

[0078] If the cavity temperature value is higher than the maximum value among the indoor temperature value, the outdoor temperature value and the third temperature threshold, the blades 113 of the first louver section 110 are controlled to rotate so that the first low emissivity surface 111 turns toward the outdoors, and the blades 113 of the second louver section 120 are controlled to rotate so that openings are formed between any adjacent blades 113 of the second louver section 120.

[0079] In this application, when the working mode is the heat preservation mode, it means that the temperature of the machine room is low and needs to be kept warm. At this time, it is necessary to avoid the heat radiation loss of the machine room. If the outdoor temperature value is less than the cavity temperature value corresponding to the cavity 140 between the first louver part 110 and the second louver part 120, and the cavity temperature value is less than the indoor temperature value, it means that the cavity temperature value is between the outdoor temperature value and the indoor temperature value. Please refer to Figure 8 , Figure 8 The structure of the heat preservation mode of the blinds 100 for the machine room provided in this application is shown as follows: Figure 1 It is necessary to control the blades 113 of the first louver part 110 to rotate so that the first low emissivity surface 111 turns toward the outdoors, so as to reduce the radiation heat exchange between the first louver part 110 and the relatively low temperature outdoor airflow, and control the blades 113 of the second louver part 120 to rotate so that the second low emissivity surface 121 turns toward the indoor direction, so as to reduce the radiation heat exchange between the second louver part 120 and the relatively high temperature indoor airflow.

[0080] If the cavity temperature value is higher than the maximum value among the indoor temperature value, the outdoor temperature value and the third temperature threshold, it means that the cavity 140 is heated up under the radiation of outdoor light, and the hotter airflow in the cavity can be exchanged with the indoor temperature, thereby increasing the indoor temperature. The blades 113 of the first louver part 110 can be controlled to rotate so that the first low emissivity surface 111 turns toward the outdoors to reduce the radiation heat exchange between the first louver part 110 and the outdoor lower temperature airflow. The blades 113 of the second louver part 120 can be controlled to rotate so that openings are formed between any adjacent blades 113 of the second louver part 120, so that the cavity 140 is connected to the indoor temperature to increase the indoor temperature.

[0081] For example, Fig. 9 The structure of the heat preservation mode of the blinds 100 for the machine room provided in this application is shown as follows: Figure 2 ,like Fig. 9As shown, the first low-emissivity surface 111 of the first louver part 110 of the louver 100 for the machine room faces the outdoor direction, and the second low-emissivity surface 121 of the second louver part 120 faces the indoor direction to reduce the radiative heat transfer between the second louver part 120 and the higher-temperature airflow indoors. Then, the blades 113 at the upper and lower ends of the second louver part 120 are rotated and inclined to form a ventilation opening, and through the chimney effect, the airflow flows in from the lower end of the second louver part 120 and flows out from the upper end, bringing the higher-temperature airflow in the cavity 140 into the room, thereby increasing the indoor temperature. For example, at noon or in the afternoon in winter, etc., at this time, T_outdoor < T_cavity > T_indoor. In order to prevent heat loss, the air with a higher temperature in the cavity 140 can be fully utilized.

[0082] Specifically, the airflow can also be accelerated by an axial flow fan. When the cavity temperature is greater than the preset temperature, the axial flow fan is turned on to strengthen the air flow and quickly cool down.

[0083] In some embodiments, the embodiments of the present application may further include:

[0084] Determine whether the louver 100 for the machine room enables the privacy mode;

[0085] If the louver 100 for the machine room enables the privacy mode, then control the light transmittance of the electrochromic film to be the lowest.

[0086] In the present application, if the privacy mode is enabled in the machine room, the light transmittance of the electrochromic film of the louver 100 for the machine room can be adjusted to the lowest to reduce the entry of outdoor light and play a role in privacy protection.

[0087] Furthermore, if the louver 100 for the machine room does not enable the privacy mode, then obtain the indoor light energy consumption value, the indoor light value measured by the illuminance sensor, and the outdoor light value;

[0088] If the indoor light energy consumption value is greater than or equal to the preset energy consumption value, then control the light transmittance of the electrochromic film to be the highest;

[0089] If the indoor light energy consumption value is less than the preset energy consumption value, the outdoor light value is greater than the indoor light value, and the indoor light value is less than the first light threshold, then increase the light transmittance of the electrochromic film until the indoor light value is greater than or equal to the first light threshold;

[0090] If the indoor light energy consumption value is less than the preset energy consumption value, the indoor light value is greater than the second light threshold, then reduce the light transmittance of the electrochromic film until the indoor light value is less than or equal to the second light threshold, and the second light threshold is greater than the first light threshold.

[0091] In the present application, the indoor lighting conditions can be determined by the indoor light energy consumption value. In order to reduce the light energy consumption, when it is detected that the indoor light energy consumption value is greater than the preset energy consumption value, the transmittance of the machine room blinds is adjusted to the maximum. The preset energy consumption value can be adjusted according to the situation, for example, the preset energy consumption value can be set to 0. When it is detected that the indoor light energy consumption value is less than the preset energy consumption value, it is also possible to judge whether the light in the machine room is sufficient by the relationship between the indoor illumination value, the first illumination threshold and the second illumination threshold. If the indoor illumination value is insufficient and the outdoor illumination value is greater than the indoor illumination value, the transmittance of the machine room blinds can be increased to allow outdoor light to enter the room. If the indoor illumination value is too strong, the transmittance of the machine room blinds can be reduced to prevent outdoor light from entering the room.

[0092] In particular, the computer room blinds 100 and the control method thereof according to the embodiment of the present application may also be applied to other technical fields, such as external windows of office buildings or external windows of residences.

[0093] The control method of the computer room shutter 100 provided in the embodiment of the present application obtains the indoor temperature value measured by the temperature sensor 135. If the indoor temperature value is less than the first temperature threshold, the working mode of the computer room shutter 100 is determined to be the insulation mode. If the indoor temperature value is greater than the second temperature threshold, the working mode of the computer room shutter 100 is determined to be the heat dissipation mode. The second temperature threshold is greater than or equal to the first temperature threshold. Based on the determined working mode, the computer room shutter 100 is adjusted according to the relationship between the indoor temperature value and the outdoor temperature value, thereby reducing the energy consumption of the cooling and heating loads of the computer room air conditioner.
