Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of indoor environment control and regulation, and particularly to an indoor temperature regulation method. Background Art
[0002] With the improvement of people's living standards, the demand for indoor temperature environment control is considered in the contemporary home design. Conventional indoor temperature control is achieved by using an air-conditioning system, but the air-conditioning system will consume a large amount of additional energy, which is not conducive to the current development direction of low-carbon, environmental protection, energy conservation and consumption reduction.
[0003] Currently, in the field of indoor environmental temperature control, it is a relatively common means to use the heat storage and release function of phase change materials to assist indoor temperature control in order to save energy. However, the application of phase change materials is usually set in the wall, which is difficult to control and has a low thermal energy utilization efficiency. CN202021235731.1 once disclosed a heat-insulating curtain blade and a shutter. Among them, the heat-insulating curtain blade is composed of two relatively arranged polyester plates, and a cavity is formed between the two relatively arranged polyester plates. The cavity is filled with sodium hydrogen phosphate dodecahydrate powder as a phase change material. A heat-insulating film is arranged on one side of one polyester plate facing away from the sodium hydrogen phosphate dodecahydrate powder to separate the heat-insulating film from the glass, prevent the glass from exploding due to too high a temperature difference, concentrate heat absorption through the heat-insulating film, and then cool the heat-insulating curtain blade by the phase change material, thereby reducing the room temperature.
[0004] The above patent sets the phase change material in the curtain blade, which can assist in realizing indoor temperature control. However, there are still the following defects. 1 In this scheme, the phase change material set in the curtain blade only has a simple heat absorption and release function, and the controllability and adjustability are poor. When the sunlight outside the window is too strong and the indoor temperature has reached or even exceeded the comfortable temperature range, effective adjustment and control cannot be achieved. At this time, continuing to deliver heat indoors will further lead to a decrease in indoor temperature comfort and an increase in cooling load. 2 The heat absorbed by the phase change material in the curtain blade can only be slowly released into the room as a whole. However, since the curtain blade is located at the window position, a large part of the released heat will be conducted back to the outside through the window again, greatly reducing the utilization efficiency of the absorbed heat. Summary of the Invention
[0005] Aiming at the deficiencies of the above prior art, the technical problem to be solved by the present invention is: how to provide an indoor temperature regulation method that absorbs heat through window blades to assist in realizing indoor environmental temperature control, so as to achieve a better temperature regulation effect and improve the utilization efficiency of the absorbed heat.
[0006] To solve the above technical problems, the present invention adopts the following technical solutions: An indoor temperature control method. When the sunlight is strong, the phase change material arranged in the blades on the indoor side of the glass window absorbs the heat of the sunlight, and releases heat to heat the indoor when the indoor temperature is lower than the comfortable temperature. It is characterized in that an endothermic material is arranged on one side of the blade, and a reflective material is arranged on the other side. It is detected and judged that when the outdoor temperature is greater than the comfortable temperature and greater than the indoor temperature, the side of the blade provided with the endothermic material is controlled to face outward. When the outdoor temperature is greater than the indoor temperature and greater than or equal to the comfortable temperature, the side of the blade provided with the reflective material is controlled to face outward.
[0007] In this way, when the outdoor sunlight is strong, the temperature rises above the comfortable temperature while the indoor temperature is lower than the comfortable temperature, controlling the side of the blade provided with the endothermic material to face outward can better absorb heat through the endothermic material and store it in the phase change material. When the phase change material is full of stored heat, it can directly transfer heat to the indoor through the phase change material. When the indoor temperature rises to reach or even exceed the comfortable temperature, controlling the side of the blade provided with the reflective material to face outward can shield the sunlight and avoid causing the indoor temperature to continue to rise and increase the cooling load. Among them, the phase change temperature of the phase change material is consistent with the comfortable temperature. In this way, the absorption of sunlight heat can be better controlled when the sunlight is strong, so as to better realize the indoor temperature control. When the sunlight weakens and the temperature drops at night, and the indoor temperature is lower than the comfortable temperature, the phase change material can be relied on to slowly release heat to increase or maintain the indoor temperature within the comfortable temperature range.
[0008] Further, the comfortable temperature ranges from 22 to 26 degrees Celsius. This range is the comfortable temperature range of the human body's sense of touch, which can better ensure the comfort of indoor personnel.
[0009] Further, when heating the indoor, the air flow and the phase change material are actively heat-exchanged and then used to heat the indoor.
[0010] In this way, compared with the passive and slow heat release of the phase change material in the background technology, the active heat exchange of the air flow can quickly displace the heat accumulated in the phase change material to heat the indoor and raise the temperature. It avoids the defect that the slow heat release of the phase change material is easy to be lost to the outside through the window, resulting in too low heat utilization efficiency.
[0011] Further, this method is realized by relying on a louver window screen device. The louver window screen device includes a plurality of blades arranged horizontally in parallel. The blades are vertically rectangular and can be folded horizontally. The phase change material is arranged inside the blades. The phase change temperature of the phase change material is the comfortable temperature of the human body. A reflective material layer capable of reflecting sunlight is arranged on one side surface of the blade, and an endothermic material layer capable of absorbing the heat of sunlight is arranged on the other side surface. It also includes a blade reversing mechanism capable of realizing the switching of the two side surfaces of the blade.
[0012] This device is particularly suitable for indoor use on the inner side of windows, especially floor-to-ceiling windows. When the sunlight outside the window starts to become stronger during the day, it controls the heat-absorbing material layer of the blade to face outward to better absorb the heat of sunlight and store it in the phase change material. When the phase change material is full of stored heat and the indoor temperature rises to the comfortable temperature range, it can control the blade to switch to the reflective material layer facing outward to maximize the reflection and shielding of sunlight, avoid the entry of heat into the room and cause an increase in the cooling load, and achieve a better energy-saving and emission-reduction effect.
[0013] Furthermore, a plurality of phase change material modules integrally in the shape of rectangular blocks are arranged vertically along the inner side of the blade, and the phase change material is arranged in each phase change material module.
[0014] In this way, the phase change material is distributed, which can better absorb the expansion deformation generated during the phase change and better ensure stability.
[0015] Furthermore, a plurality of independent encapsulation blocks are arranged in an array in each phase change material module, and the phase change material is encapsulated in each encapsulation block.
[0016] This can better absorb the expansion deformation generated by the phase change material during the phase change, improve the structural stability of the device, and at the same time can also facilitate the more efficient heat exchange between the phase change material and the air flow.
[0017] Furthermore, the phase change material is a solid-liquid phase change material.
[0018] Furthermore, a rapid heat exchange mechanism is also provided. The rapid heat exchange mechanism includes a blower located at one end of the upper or lower part of the device, an air outlet cylinder correspondingly installed at the lower or upper part of the device for the blower, and connection cylinders fixedly installed at the upper and lower ends of each blade along the thickness direction of the blade. One side of the middle position of the connection cylinder is connected to the air duct inside the blade. The air duct connects to each phase change material module inside the blade and passes through the peripheral position of each encapsulation block. One end of the connection cylinder is provided with an outward-expanded conical insertion port, and the other end is provided with a matching straight cylindrical insertion joint. The air outlet cylinder and the blower are each provided with a matching insertion port facing one end of the connection cylinder, and the non-connection end of the connection cylinder at the position farthest from the blower and the air outlet cylinder is designed to be closed.
[0019] In this way, when the phase change material is full of thermal energy and the indoor temperature is lower than the human comfort temperature and it is necessary to rely on the phase change material to supply heat to the room, the blades can be adjusted to the folded state. At this time, each plug connector is inserted into the adjacent socket to form an air flow channel. Relying on the blower to blow air, the air flow enters the air flow channel and actively exchanges heat with the phase change material and warms up when passing through each encapsulation block to obtain hot air, and is blown out from the air outlet cylinder to heat the room. In this way, the folded state of the blades can reduce the heat loss caused by the conduction of heat to the outside of the window. At the same time, after the blades are folded, the air flow channel is connected, so that the heat stored in the phase change material can be efficiently and quickly replaced by the air flow to supply heat to the room, avoiding the situation that a large amount of heat overflows from the window due to the slow release of heat by the phase change material, resulting in waste. The heating rate of the room is increased and the utilization efficiency of thermal energy is greatly improved.
[0020] Further, an air outlet pipe is externally connected to the air outlet cylinder.
[0021] In this way, the air outlet can be set at the position in the room where centralized heating is required through the air outlet pipe, and the indoor temperature adjustment can be better realized.
[0022] Further, a connecting channel is vertically arranged on one side of the connecting cylinder and is connected to the air duct inside the blade. A matching block is arranged at the interface where the connecting channel is connected to the connecting cylinder. One end of the block facing the socket of the connecting cylinder has a receiving force surface for the plug connector of the adjacent connecting cylinder to contact and receive force when inserted. The other end of the block is connected with a telescopic spring, and the other end of the telescopic spring abuts against a step surface fixed inside the connecting cylinder. An air outlet hole is also arranged on the side surface of the plug connector of the connecting cylinder, and the air outlet hole can be arranged to coincide with the interface of the connecting channel of the adjacent connecting cylinder when the connecting cylinders are inserted into each other.
[0023] In this way, when the blades are folded so that the adjacent connecting cylinders are inserted into each other, the plug connector can be relied on to push the block away to open the connecting channel and communicate with the air duct inside the blade to realize air supply. When the blades are unfolded and the connecting cylinders are separated from each other, the block can automatically stretch out to shield the interface position of the connecting cylinder, preventing small animals such as cockroaches from entering the air duct inside the blade and causing damage.
[0024] Further, the blade reversing mechanism includes an upper sliding rod arranged horizontally in a U shape above the blades, and also includes suspension rings connected to the upper ends of the blades. The suspension rings are slidably suspended on the upper sliding rod, and the edges of adjacent blades are connected in a foldable and flexible manner.
[0025] In this way, it is convenient to pull the blades to slide along the upper sliding rod by relying on the suspension rings. When the blades are in the two ends of the U shape, the outer side faces inwards or outwards to realize reversing, which has the characteristics of simple structure and convenient reversing.
[0026] Further, an upper guide rail is also arranged in parallel at intervals at the upper end of the upper sliding rod. Two remote control cars are fitted and installed on the upper guide rail. One remote control car is connected to the blade at one side edge position, and the other remote control car is connected to the blade at the other side edge position. The remote control cars are communicatively connected to the control center.
[0027] In this way, when needed, the control center can command the two remote control cars to move along the upper guide rail, and realize the automatic switching control of the blade direction, which is more convenient and fast.
[0028] Further, the blade commutation mechanism further includes a lower sliding rod symmetrically arranged with the upper sliding rod below the blade. A connecting ring is arranged at the lower end of each blade and sleeved on the lower sliding rod. A lower guide rail is also arranged at intervals below the lower sliding rod. Two remote control cars communicatively connected to the control center are fitted and installed on the lower guide rail. One remote control car is connected to the blade at one side edge position, and the other remote control car is connected to the blade at the other side edge position.
[0029] In this way, by controlling from the upper and lower directions, the switching control of the blade can be realized more stably.
[0030] Further, a phase change degree detection mechanism is also arranged on at least one blade. The phase change degree detection mechanism includes a detection air pipe vertically connecting all the phase change material modules on the blade. The detection air pipe penetrates and is encapsulated inside all the encapsulation blocks in a vertical column of the phase change material modules. An air bag is arranged at the position of the detection air pipe inside each encapsulation block. The upper and lower ends of the detection air pipe are hermetically arranged and at least one end is located in a detection chamber. A pressure sensor is arranged on the inner wall of the detection chamber. The pressure sensor abuts against an expandable force application end of the detection air pipe. The pressure sensor is connected to the control center.
[0031] In this way, when the phase change material absorbs heat and undergoes a phase change conversion, the volume expansion can squeeze the air bag, relieve the expansion deformation pressure of the encapsulation block, and better ensure the stability of the device. At the same time, after the air bag is squeezed, the detection air pipe can transmit the internal gas pressure to the end to cause the force application end to expand, increasing the pressure on the pressure sensor. Therefore, the pressure sensor can judge whether the phase change material has started to undergo a phase change and whether all the phase changes have been completed by detecting the change in pressure, and better provide a basis for control judgment.
[0032] Further, it also includes an automatic control system. The automatic control system includes the control center and the phase change detection mechanism, and also includes an indoor temperature sensor arranged indoors and an outdoor temperature sensor arranged outdoors. An automatic control module is arranged in the automatic control system. The automatic control module can implement the following control procedures according to the detection information: when it is detected that the outdoor temperature is higher than the comfortable temperature (the comfortable temperature is the same as the phase change temperature) and higher than the indoor temperature, control the remote control trolley to manipulate the blades to be converted into a folded and retracted state (so that the outdoor sunlight directly irradiates the indoor for heating). At this time, when it is detected that there is still phase change energy in the phase change material that has not been released, control the blower to start, inhale the indoor low-temperature gas into the air duct for heat exchange, and blow out hot air from the air outlet cylinder to heat the indoor until the blower stops after the phase change material releases all the phase change energy; when it is detected that the outdoor temperature is higher than the comfortable temperature and the indoor temperature also rises to reach or exceed the comfortable temperature, first control the remote control trolley to manipulate the blades to be in an unfolded state with the heat absorption material layer facing outward to absorb solar light for heat storage of the phase change material. Until it is detected that the heat storage phase change of the phase change material is completed, then control the remote control trolley to manipulate the blades to be converted into the reflective material layer facing outward (to better reflect the solar light energy out of the window).
[0033] Therefore, in this way, without manual operation, the automatic control process of the indoor temperature can be better realized.
[0034] In summary, the present invention can absorb heat through the window blades to assist in realizing the control of the indoor environmental temperature, achieving a better temperature control effect and improving the utilization efficiency of solar light heat.

[0042] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific implementation modes.
[0043] Implementation mode: An indoor temperature control method. When the sunlight is strong, the phase change material arranged in the blades on the indoor side of the glass window absorbs the heat of the sunlight, and releases heat to heat the indoor when the indoor temperature is lower than the comfortable temperature. Its characteristic lies in that an endothermic material is arranged on one side of the blade, and a reflective material is arranged on the other side. It is detected and judged that when the outdoor temperature is greater than the comfortable temperature and greater than the indoor temperature, the side of the blade provided with the endothermic material is controlled to face outward. When the outdoor temperature is greater than the indoor temperature and greater than or equal to the comfortable temperature, the side of the blade provided with the reflective material is controlled to face outward.
[0044] In this way, when the outdoor sunlight is strong, the temperature rises to be higher than the comfortable temperature while the indoor temperature is lower than the comfortable temperature, controlling the side of the blade provided with the endothermic material to face outward can better absorb heat through the endothermic material and store it in the phase change material. When the phase change material is full of heat storage, it can directly deliver heat to the indoor through the phase change material. And when the indoor temperature rises to reach or even exceed the comfortable temperature, controlling the side of the blade provided with the reflective material to face outward can shield the sunlight and avoid causing the indoor temperature to continue to rise, resulting in an increase in the cooling load. Among them, the phase change temperature of the phase change material is consistent with the comfortable temperature. In this way, the absorption of the heat of the sunlight can be better controlled when the sunlight is strong, so as to better realize the indoor temperature control. When the sunlight weakens at night and the temperature drops, and the indoor temperature is lower than the comfortable temperature, the heat can be slowly released by relying on the phase change material to increase or maintain the indoor temperature within the comfortable temperature range.
[0045] During implementation, the comfortable temperature ranges from 22 to 26 degrees Celsius. This range is the comfortable temperature range of the human body's sense of touch, which can better ensure the comfort of indoor personnel.
[0046] In this implementation mode, when heating the indoor, the air flow and the phase change material are actively heat-exchanged and then used to heat the indoor.
[0047] In this way, compared with the passive and slow heat release of the phase change material in the background technology, by actively heat-exchanging with the air flow, the heat accumulated in the phase change material can be quickly replaced to heat the indoor and raise the temperature. It avoids the defect that the slow heat release of the phase change material is easy to be lost to the outside through the window, resulting in too low heat utilization efficiency.
[0048] In this implementation mode, this method is realized by relying on a louver window screen device. For the louver window screen device, see Figure 1-7, including several blades 1 arranged horizontally side by side. The blades 1 are vertically rectangular and can be folded horizontally. A phase change material is arranged inside the blades 1, and the phase change temperature of the phase change material is the comfortable temperature of the human body. A reflective material layer capable of reflecting sunlight is arranged on one side surface of the blade, and a heat-absorbing material layer capable of absorbing the heat of sunlight is arranged on the other side surface. It also includes a blade reversing mechanism capable of switching the two side surfaces of the blade.
[0049] This device is particularly suitable for use inside a room, especially on the inner side of floor-to-ceiling windows. When the sunlight outside the window starts to become stronger during the day, the heat-absorbing material layer of the blade can be controlled to face outward to better absorb the heat of sunlight and store it in the phase change material. When the phase change material is full of stored heat and the indoor temperature rises to the comfortable temperature range, the blade can be controlled to switch to the reflective material layer facing outward to reflect and shield the sunlight to the greatest extent, avoiding the entry of heat into the room and causing an increase in the cooling load, achieving a better energy-saving and emission-reduction effect.
[0050] Among them, a plurality of phase change material modules 4 integrally in the shape of rectangular blocks are arranged vertically inside the blade 1, and the phase change material is arranged in each phase change material module 4.
[0051] In this way, the phase change material is distributed, which can better absorb the expansion deformation generated during the phase change and better ensure stability.
[0052] Among them, a plurality of independent encapsulation blocks 5 are arranged in an array inside each phase change material module 4, and the phase change material is encapsulated in each encapsulation block 5.
[0053] This can better absorb the expansion deformation generated by the phase change material during the phase change, improve the structural stability of the device, and at the same time facilitate the phase change material to exchange heat with the air flow more efficiently.
[0054] Among them, the phase change material is a solid-liquid phase change material.
[0055] Among them, a rapid heat exchange mechanism is also provided. The rapid heat exchange mechanism includes a blower 6 located at one end of the upper or lower part of the device, an air outlet cylinder 7 installed corresponding to the blower at the lower or upper part of the device, and connecting cylinders 8 fixedly installed at the upper and lower ends of each blade along the thickness direction of the blade. One side of the middle position of the connecting cylinder 8 is connected to the air duct 9 inside the blade. The air duct connects to each phase change material module inside the blade and passes through the peripheral position of each encapsulation block. One end of the connecting cylinder is provided with an outwardly expanding conical socket 10, and the other end is provided with a matching straight socket 11. The air outlet cylinder and the blower are each provided with matching sockets facing one end of the connecting cylinder, and the non-connecting end of the connecting cylinder at the position farthest from the blower and the air outlet cylinder is designed to be closed.
[0056] In this way, when the phase change material is filled with thermal energy and the indoor temperature is lower than the comfortable temperature of the human body and the indoor heating needs to rely on the phase change material, the blades can be adjusted to the folded state. At this time, each plug connector is inserted into the adjacent socket to form an air flow channel. Relying on the blower to blow air, the air flow enters the air flow channel and actively exchanges heat with the phase change material when passing through each encapsulation block and is heated to obtain hot air, and is blown out from the air outlet cylinder to heat the indoor. In this way, the folded state of the blades can reduce the heat loss caused by the conduction of heat to the outside of the window. At the same time, after the blades are folded, the air flow channel is connected, so that the heat accumulated in the phase change material can be efficiently and quickly replaced by the air flow to heat the indoor, avoiding the situation that a large amount of heat overflows from the window due to the slow release of heat by the phase change material, resulting in waste. The heating rate of the indoor temperature is increased and the utilization efficiency of thermal energy is greatly improved.
[0057] Wherein, an air outlet pipe (not shown in the figure) is externally connected to the air outlet cylinder 7.
[0058] In this way, the air outlet can be arranged at the position in the room where centralized heating is required through the air outlet pipe, so as to better realize the indoor temperature adjustment.
[0059] Wherein, a connecting channel 12 is vertically arranged on one side of the connecting cylinder 8 and is connected to the air duct 9 in the blade. A matching block 13 is arranged at the interface where the connecting channel is connected to the connecting cylinder. One end of the block 13 facing the socket of the connecting cylinder has a receiving force surface for the plug connector of the adjacent connecting cylinder to contact and receive force when inserted. The other end of the block is connected with a telescopic spring 14, and the other end of the telescopic spring 14 abuts against a step surface fixed in the connecting cylinder. An air outlet hole 15 is also arranged on the side surface of the plug connector of the connecting cylinder, and the air outlet hole 15 can coincide with the interface of the connecting channel of the adjacent connecting cylinder when the connecting cylinders are inserted into each other.
[0060] In this way, when the blades are folded so that the adjacent connecting cylinders are inserted into each other, the block can be pushed open by the plug connector to open the connecting channel and communicate with the air duct in the blade to realize air supply. When the blades are unfolded and the connecting cylinders are separated from each other, the block can automatically expand to shield the interface position of the connecting cylinder, preventing small animals such as cockroaches from entering the air duct inside the blade and causing damage.
[0061] Wherein, the blade reversing mechanism includes an upper sliding rod 16 arranged horizontally in a U shape above the blade, and also includes a hanging ring 17 connected to the upper end of each blade. The hanging ring 17 is slidably hung on the upper sliding rod 16, and the edges of adjacent blades are flexibly connected and can be folded.
[0062] In this way, it is convenient to pull the blade to slide along the upper sliding rod by relying on the hanging ring. When the blade is located at the two ends of the U shape, the outer side faces in or out to realize reversing, which has the characteristics of simple structure and convenient reversing.
[0063] Among them, an upper guide rail 18 is also arranged in parallel at intervals at the upper end of the upper sliding rod. Two remote control cars 19 are fitted and installed on the upper guide rail 18. One remote control car is connected to the blade at one side edge position, and the other remote control car is connected to the blade at the other side edge position. The remote control cars are in communication connection with the control center 20.
[0064] In this way, when needed, the control center can command the two remote control cars to move along the upper guide rail, and realize the automatic switching control of the blade direction, which is more convenient and fast.
[0065] Among them, the blade commutation mechanism further includes a lower sliding rod symmetrically arranged with the upper sliding rod under the blade. Connecting rings are arranged at the lower ends of the blades and sleeved on the lower sliding rod. A lower guide rail is also arranged at intervals under the lower sliding rod. Two remote control cars in communication connection with the control center are fitted and installed on the lower guide rail. One remote control car is connected to the blade at one side edge position, and the other remote control car is connected to the blade at the other side edge position.
[0066] In this way, by controlling from the upper and lower directions, the switching control of the blade can be realized more stably.
[0067] Among them, a phase change degree detection mechanism is also arranged on at least one blade. The phase change degree detection mechanism includes a detection air pipe 25 connected vertically to all the phase change material modules on the blade. The detection air pipe penetrates and is encapsulated inside all the encapsulation blocks in a vertical column of the phase change material modules. An air bag 26 is arranged at the position of the detection air pipe inside each encapsulation block 5. The upper and lower ends of the detection air pipe are hermetically arranged and at least one end is located in a detection chamber 27. A pressure sensor 28 is arranged on the inner wall of the detection chamber. The pressure sensor 28 abuts against an expandable force application end of the detection air pipe 25. The pressure sensor is connected to the control center 20.
[0068] In this way, when the phase change material absorbs heat and undergoes a phase change conversion, the volume expansion can squeeze the air bag, relieve the expansion deformation pressure of the encapsulation block, and better ensure the stability of the device. At the same time, after the air bag is squeezed, the detection air pipe can transmit the internal gas pressure to the end to cause the force application end to expand, increasing the pressure on the pressure sensor. Therefore, the pressure sensor can judge whether the phase change material has started to undergo a phase change and whether all the phase changes have been completed by detecting the change in pressure, and better provide a basis for control judgment.
[0069] Among them, it further includes an automatic control system. The automatic control system includes the control center and the phase change detection mechanism, and also includes an indoor temperature sensor arranged indoors and an outdoor temperature sensor arranged outdoors. An automatic control module is arranged in the automatic control system. The automatic control module can implement the following control procedures according to the detection information: when it is detected that the outdoor temperature is higher than the comfortable temperature (the comfortable temperature is the same as the phase change temperature) and higher than the indoor temperature, control the remote control vehicle to operate the blades to convert into a folded and retracted state (so that the outdoor sunlight directly irradiates the indoor for heating). At this time, when it is detected that there is still phase change energy in the phase change material that has not been released, control the blower to start, inhale the indoor low-temperature gas into the air duct for heat exchange, and blow out hot air from the air outlet cylinder to heat the indoor until the blower stops after the phase change material releases all the phase change energy; when it is detected that the outdoor temperature is higher than the comfortable temperature and the indoor temperature also rises to reach or exceed the comfortable temperature, first control the remote control vehicle to operate the blades to be in the unfolded state with the heat absorption material layer facing outward to absorb sunlight for heat storage of the phase change material. Until it is detected that the phase change material has completed heat storage and phase change, then control the remote control vehicle to operate the blades to convert to the reflective material layer facing outward (to better reflect the solar light energy out of the window).
