Description

Technical Field

[0001] This application relates to the technical field of testing, and in particular to a device and method for measuring the additional thermal resistance of a roller shutter. Background Technology

[0002] Roller blinds are a type of sun-shading product installed on the inside or outside of windows, serving to block sunlight and keep the room cool. During installation, threaded holes must first be drilled in the wall above the window, then bolts are used to fix the bracket to the wall, and finally the roller blind is clipped onto the bracket to complete the installation.

[0003] Currently, there are many types of roller blinds. When purchasing, users often value light blocking and heat insulation functions the most. Light blocking performance can be measured by the light blocking rate of the roller blind, which can be easily measured with a portable light transmittance meter. However, heat insulation is difficult to measure.

[0004] When roller blinds and other sun-shading products are used in combination with windows, a relatively sealed air cavity is formed between them, the windows, and the window openings. This air cavity increases the thermal resistance of the building envelope. The increased thermal resistance due to the use of sun-shading products is called additional thermal resistance. Increased thermal resistance means a lower heat transfer coefficient, which can reduce building heating or cooling energy consumption and improve energy efficiency.

[0005] Additional thermal resistance is a specific parameter of shading products, reflecting their impact on the thermal resistance of the building envelope. While additional thermal resistance most directly reflects the effect of shading products on the heat transfer coefficient of the building envelope, its measurement is difficult. According to the "Test Methods for Physical Performance of Building Shading Products," the formula for calculating additional thermal resistance is: Where ∆R is the additional thermal resistance; U is the heat transfer coefficient of the window with the extended roller blind installed; This represents the heat transfer coefficient of the window without the roller blind installed. Therefore, to measure the additional thermal resistance of the roller blind, it is necessary to measure the heat transfer coefficient of the window with the roller blind installed.

[0006] The heat transfer coefficient of windows with roller blinds is mainly measured by the "heat box method". To measure the heat transfer coefficient of different models of roller blinds, bolt holes of different sizes need to be made on the wall above the window. The wall is easily damaged, and the manual disassembly and installation of roller blinds is cumbersome, making it difficult for merchants or testing agencies to obtain the heat transfer coefficients of different types of roller blinds in batches.

DETAILED DESCRIPTION

[0052] The following will be described in detail below with reference to the accompanying drawings Figure 1 - the accompanying drawings Figure 10 The application will be described in further detail.

[0053] The embodiment of the application discloses a roller shutter additional heat resistance measuring device.

[0054] Reference will be made to Figure 1 and Figure 2 ​​The application relates to a curtain additional heat resistance measuring device, which comprises a filling wall 11 for mounting a curtain 3, a wall surface 12 arranged between a cold chamber and a hot chamber on the filling wall 11 and protruding from the wall surface 12 on the side close to the curtain, a window 1 arranged on the filling wall 11, and the curtain 3 to be measured covering the surface of the window 1; the device further comprises a mounting frame 2 arranged on the mounting side of the curtain 3, the mounting frame 2 being provided with a mounting plate 4 for mounting the curtain 3, the curtain 3 being arranged on one side of the mounting plate 4 through a clamping assembly 41, the bottom of the mounting frame 2 being provided with a sliding assembly 8, the mounting plate 4 being driven by the sliding assembly 8 to move in the direction close to or away from the window 1, so that the other side of the mounting plate 4 is attached to the filling wall 11, the state of the curtain 3 being mounted on the filling wall 11 being simulated; and a flow guide plate 9 is further arranged on the mounting frame 2, the flow guide plate 9 being located on the side of the curtain 3 away from the window, and being used for preventing the air flow in the cold chamber or the hot chamber from directly blowing the curtain 3; the hemispherical emissivity of the surface of the flow guide plate 9 facing the curtain 3 is greater than 0.85, the distance between the flow guide plate 9 and the window 1 is 150mm-300mm after the side of the mounting plate 4 is attached to the filling wall 11, and the size of the flow guide plate 9 is greater than that of the curtain 3; a plurality of temperature measuring devices are further arranged between the flow guide plate 9 and the soft curtain, and are used for measuring the temperature; and the temperature measuring devices can be hung between the flow guide plate 9 and the curtain 3 through a rope.

[0055] With reference to Figure 1 And Figure 2 , the mounting frame 2 is further provided with an unloading assembly 5, the unloading assembly 5 being used for unloading the mounting plate 4 arranged on the mounting frame 2; the upper portion of the mounting frame 2 is provided with a storage rack 6 for storing a plurality of mounting plates 4, the plurality of mounting plates 4 on the storage rack 6 being arranged in the moving direction of a supporting frame 62, and the mounting plate 4 being provided with the curtain 3; after the measurement of one curtain 3 is completed, the mounting plate 4 on the mounting frame 2 can be unloaded through the unloading assembly 5, then the mounting frame 2 is moved to the lower portion of the mounting plate 4 on the storage rack 6, then the mounting plate 4 on the storage rack 6 falls on the mounting frame 2, and then the measurement of the next curtain 3 can be carried out.

[0056] It should be noted that when the curtain 3 covers the filling wall 11, the curtain 3 and the window 1 form a relatively closed air cavity, and the curtain 3 cooperates with the air cavity to realize the heat insulation effect; in the actual use scene of the curtain 3, the support 31 for fixing the curtain 3 is directly fixed on the wall, and in the scheme of the application, the support 31 is first mounted on the mounting plate 4 and then covers the filling wall 11, so that the thickness of the air cavity in the embodiment is greater than that in the actual use scene, and the difference between the thicknesses is the thickness of one mounting plate 4, therefore, in the embodiment of the application, a groove with a thickness matching that of the mounting plate 4 is formed in the filling wall 11, the groove is opposite to the mounting plate 4, and when the mounting plate 4 is attached to the filling wall 11, the mounting plate 4 can be clamped in the groove, so that the distance between the curtain 3 and the window 1 is closer, the thickness of the air cavity is more consistent with the actual situation, and the heat transfer coefficient measurement result is more accurate.

[0057] Currently, when measuring the heat transfer coefficient of the roller shutter 3, the roller shutter 3 needs to be installed on the window 1 to simulate the actual installation state of the roller shutter 3, and then the heat transfer coefficient of the window 1 installed with the roller shutter 3 is measured. The heat transfer coefficient is measured by the "heat box method". The specific measurement method is as follows: the window 1 is installed on the wall 12 between the cold room and the hot room, wherein the wall 12 is provided with a test piece frame, the window 1 is arranged in the test piece frame, and the gap between the window 1 and the test piece frame is filled by the filling wall 11. The cold room is cooled by a refrigeration device to maintain a constant temperature, and the hot room is heated by a heating device to maintain another constant temperature. When the temperatures in the cold room and the hot room tend to be stable, the power consumed by the refrigeration device in the cold room and the heating device in the hot room is calculated in combination with other parameters to obtain the heat transfer coefficient of the window 1.

[0058] In the prior art, in order to measure the heat transfer coefficient of the window 1 installed with the roller shutter 3, the roller shutter 3 needs to be installed on the filling wall 11 above the window 1 on one side of the cold room or the hot room. The cold room represents the outdoor environment, and the hot room represents the indoor environment. If the roller shutter 3 is installed indoors, the roller shutter 3 is arranged on the window 1 on the side of the hot room in this embodiment. In the prior art, when measuring the heat transfer coefficient of the roller shutter 3, the roller shutter 3 needs to be installed on the window 1. First, a hole is drilled in the filling wall 11 above the window 1, a bracket 31 is fixed to the wall 12 by a bolt, and then the roller shutter 3 is hung on the bracket 31 to complete the fixation of the roller shutter 3. However, the drilling operation damages the filling wall 11. When multiple different types of roller shutters 3 need to be measured, multiple drilling operations will cause irreversible damage to the filling wall 11. On the other hand, when replacing the roller shutter 3, the operator needs to open the door to enter the cold room or the hot room, which will cause the hot air from the outside to enter the cold room or the cold air from the outside to enter the hot room, affecting the overall temperature balance. Before the next measurement, a long time needs to be waited until the temperature stabilizes, increasing the time of each measurement and leading to low measurement efficiency.

[0059] In the scheme of this embodiment, the roller shutter 3 is fixed on the mounting plate 4. During measurement, the mounting plate 4 installed with the roller shutter 3 is closely attached to the filling wall 11, simulating the state that the roller shutter 3 is installed on the filling wall 11, and avoiding direct drilling on the filling wall 11. In the scheme of this embodiment, the mounting rack 2 is provided with the unloading assembly 5, and the upper side of the mounting rack 2 is provided with the storage rack 6. After one roller shutter 3 is measured, the mounting plate 4 arranged on the mounting rack 2 can be unloaded by the unloading assembly 5, and then a new mounting plate 4 is lowered from the storage rack 6 to the mounting rack 2, thereby completing the replacement of the roller shutter 3. In this replacement mode, the door of the cold room or the hot room does not need to be opened, the influence on the stability of the cold room or the hot room is small, the balance can be reached faster, and the measurement efficiency is higher.

[0060] Referring to Figure 4 , Figure 5 and Figure 6 , the storage rack 6 includes a hollow box body 61 arranged above the support frame 62 and the support frame 62 for supporting the box body 61, the bottom of the support frame 62 is supported on the ground, and the top of the support frame 62 is fixed with the box body 61. A plurality of support frames 62 are arranged along the length direction of the box body 61, which stably supports the box body 61, so that the support frame 62 is not easy to hinder the movement of the mounting frame 2 at the bottom of the box body 61, and the support frame 62 provides stable support for the box body 61. In some embodiments, the box body 61 can also be installed on the top of the room, as long as the space below the box body 61 is reserved for the mounting frame 2 to pass through. A plurality of mounting plates 4 on which the roller shutter 3 is mounted are arranged in the box body 61, and the bottom surface of the box body 61 is provided with a drop opening 63 for the mounting plate 4 to fall, the drop opening 63 is rectangular and matches the size of the mounting plate 4 on which the roller shutter 3 is mounted, and the bottom of each mounting plate 4 is correspondingly provided with a drop opening 63. The drop opening 63 is provided with a blocking rod 64, which is located at the bottom of the mounting plate 4 and supports the mounting plate 4, and each mounting plate 4 is correspondingly provided with two blocking rods 64, which support the mounting plate 4 from both ends of the mounting plate 4 to prevent the mounting plate 4 from falling from the drop opening 63. The height of the top of the mounting frame 2 is higher than the height of the bottom of the blocking rod 64, so when the mounting frame 2 moves towards the bottom of the mounting plate 4, the top of the mounting frame 2 will contact the bottom of the blocking rod 64, push the blocking rod 64 to move and separate from the mounting plate 4, and then the mounting plate 4 losing the support of the blocking rod 64 will fall from the drop opening 63. The bottom of the blocking rod 64 has an abutting block 641, which can facilitate the contact between the top of the mounting frame 2 and the blocking rod 64.

[0061] Referring to Figure 4 , Figure 5 and Figure 6The inside of the box 61 is also provided with a guide rail 65, which is used to constrain the moving direction of the guide rail 65. One end of the guide rail 65 is flush with the bottom of the mounting plate 4, and the other end extends away from the window 1 and is inclined upward. The stopper 64 is slidingly arranged in the guide rail 65, and the height of the stopper 64 increases when the stopper 64 moves in the guide rail 65. Since multiple mounting plates 4 provided with the roller shutter 3 are arranged in the box 61, when the mounting rack 2 receives the mounting plate 4 closest to the window 1 and completes the measurement of the roller shutter 3 on the mounting plate 4, the mounting rack 2 will pass through the drop opening 63 below the closest mounting plate 4 and continue to move away from the window 1 until it reaches the next drop opening 63. Therefore, the stopper 64 at the previous drop opening 63 should not block the progress of the mounting plate 4. Therefore, in this embodiment, the guide rail 65 is inclined upward, and the height of the stopper 64 increases when the stopper 64 moves in the guide rail 65. The guide rail 65 is also provided with a clamping groove 651, and the stopper 64 is provided with a clamping block 642 at a corresponding position. When the stopper 64 is pushed to the highest position, the clamping block 642 on the stopper 64 is clamped in the clamping groove 651, so that the stopper 64 will not fall. When the clamping block 642 is clamped in the clamping groove 651, the height of the abutting block 641 at the bottom of the stopper 64 will be higher than the top of the mounting rack 2, so that the abutting block 641 will not block the mounting rack 2 when the mounting rack 2 passes through the drop opening 63 again.

[0062] Referring to Figure 4 , Figure 5 and Figure 6 , four limiting blocks 66 are arranged in the box 61. Two of the limiting blocks 66 are arranged at one end of the mounting plate 4 in the length direction and clamp the mounting plate 4 from both sides in the width direction of the mounting plate 4. The other two limiting blocks 66 are arranged at the other end of the mounting plate 4 in the length direction and also clamp the mounting plate 4 from both sides in the width direction of the mounting plate 4, so that the mounting plate 4 can only move up and down and cannot tilt left and right, thereby preventing the mounting plate 4 from falling over when it falls from the drop opening 63.

[0063] Referring to Figure 4 , the roller shutter 3 is in a rolled-up state in the box 61. The bottom end of the roller shutter 3 body is provided with a counterweight 32, which is tied to the bottom of the roller shutter 3 by a rope. When the roller shutter 3 is in the box 61, the counterweight 32 is placed on the bottom plate of the box 61. When the roller shutter 3 falls onto the mounting rack 2 along with the mounting plate 4, the counterweight 32 falls from the drop opening 63 along with the roller shutter 3 and pulls the roller shutter 3 open by the force of gravity. This achieves automatic opening of the roller shutter 3.

[0064] Referring to Figure 7 and Figure 8The mounting frame 2 comprises two vertically arranged support plates 21, which are arranged at the two ends of the mounting plate 4 in the length direction, and the lower ends of the support plates 21 are arranged on the ground. The upper ends of the two support plates 21 are provided with a first clamping plate 22 and a second clamping plate 23. The first clamping plate 22 is arranged on the side away from the window 1, and the second clamping plate 23 is arranged on the side close to the window 1. The first clamping plate 22 and the second clamping plate 23 form a space for accommodating the mounting plate 4. A structure for supporting the mounting plate 4 is arranged between the first clamping plate 22 and the second clamping plate 23. The structure cooperates with the first clamping plate 22 and the second clamping plate 23 to support the mounting plate 4, so that the mounting plate 4 is kept in an upright state and can better fit the infilled wall 11. When the support plate 21 moves towards the bottom of the mounting plate 4 on the storage rack 6, the top of the first clamping plate 22 first contacts the abutting block 641 and pushes the blocking rod 64 to move, so that the top of the first blocking rod 64 is inclined away from the window 1, and the top of the first clamping plate 22 and the second clamping plate 23 present a funnel shape, which can better receive the mounting plate 4.

[0065] Referring to Figure 7 and Figure 8 , the structure for supporting the mounting plate 4 is the unloading assembly 5. The same unloading assembly 5 is symmetrically arranged on the two mounting plates 4. The unloading assembly 5 comprises a support block 51 arranged on the mounting frame 2, a guide rod 52, a guide groove 53 and a first lead screw assembly 54. The first clamping plate 22 and the second clamping plate 23 are horizontally provided with a support opening 55. The support block 51 is slidingly arranged in the support opening 55, and the support block 51 closes the gap between the first clamping plate 22 and the second clamping plate 23, so that the support block 51 can support the mounting plate 4. When the support block 51 supports the mounting plate 4, the height of the mounting plate 4 should be just aligned with the infilled wall 11 above the window 1, so as to simulate the normal installation of the roller shutter 3 on the infilled wall 11. The side of the support block 51 away from the window 1 is provided with the guide groove 53, and the support plate 21 is provided with the guide rod 52 in the horizontal direction. The guide rod 52 is slidingly arranged in the guide groove 53, so that the support block 51 can reciprocate in the direction close to or away from the window 1. The support block 51 can be separated from the support of the mounting plate 4 when it is away from the window 1. The first lead screw assembly 54 comprises a first motor 542 fixed on the support plate 21 and a first lead screw 541 connected with the output end of the first motor 542.

[0075] S5: After the measurement is completed, the mounting frame 2 is driven to move away from the window 1, and the installation plate 4 installed on the mounting frame 2 is unloaded by the unloading assembly 5;

[0076] S6: The mounting frame 2 is driven to move below the installation plates 4 on the storage rack 6, and the installation plates 4 falling from the storage rack 6 are received;

[0077] S7: The steps S3-S6 are repeated until the roller shutters 3 on the storage rack 6 are completely detected.

[0078] By this measurement method, a plurality of roller shutters 3 can be automatically measured without opening the door of the cold room or the hot room, the temperature of the cold room or the hot room can reach equilibrium faster, and the measurement efficiency of the heat transfer coefficient is improved.

[0079] Specifically, the method for measuring additional thermal resistance of a roller shutter disclosed in the embodiments of the present application is as follows: a plurality of roller shutters 3 to be measured are prepared, the plurality of roller shutters 3 are respectively installed on different installation plates 4, and the installation of the roller shutter 3 in the cold room is taken as an example. The installation plate 4 provided with the roller shutter 3 is placed inside the box body 61 on the storage rack 6. In this embodiment, the plurality of roller shutters 3 are numbered from the direction close to the window 1 to the direction away from the window 1, and the numbers of the plurality of roller shutters 3 are 1, 2, 3, and so on. An installation plate 4 provided with a roller shutter 3 is arranged on the mounting frame 2. The mounting frame 2 and the window 1 are driven to approach by the driving assembly 82 until the installation plate 4 is attached to the filled wall 11, so as to simulate the installation state of the roller shutter 3. The cold room is closed, the refrigeration equipment of the cold room and the heating equipment of the hot room are started, and the heat transfer coefficient of the window 1 provided with the roller shutter 3 is measured by using the method required in the specification.

[0080] After the measurement is completed, the mounting frame 2 is driven away from the window 1 by the driving assembly 82, and when the mounting frame 2 is between the window 1 and the No. 1 roller shutter 3, the support block 51 for supporting the mounting plate 4 is driven by the first screw rod assembly 54 to make the mounting plate 4 fall from the gap between the first clamping plate 22 and the second clamping plate 23 to the unloading area 7, and the support block 51 is reset by the first screw rod assembly 54 after the mounting plate 4 falls, at this time, there is no roller shutter 3 on the mounting frame 2; because the first clamping plate 22 and the second clamping plate 23 are provided with a clearance higher than the height of the mounting plate 4 at the end close to the ground. Therefore, the mounting frame 2 can continue to move away from the window 1 through the unloading area 7, and when the mounting frame 2 reaches below the No. 1 roller shutter 3, the top of the first clamping plate 22 abuts against the bottom of the stop rod 64 on the storage rack 6, and with the movement of the mounting frame 2, the first clamping plate 22 constantly pushes the stop rod 64 to move away from the window 1, and when the stop rod 64 moves a certain distance, the stop rod 64 cannot support the mounting frame 2 on the stop rod 64, so the mounting frame 2 with the No. 1 roller shutter 3 falls through the drop opening 63 to the mounting frame 2, the counterweight 32 installed on the roller shutter 3 falls and drives the roller shutter 3 to open, and the mounting frame 2 continues to move away from the window 1 until the stop rod 64 is clamped on the clamping groove 651 to prevent the stop rod 64 from blocking the mounting frame 2 when the mounting frame 2 passes next time; then the mounting frame 2 is driven to approach the window 1 to complete the measurement of the No. 1 roller shutter 3, and after the measurement is completed, the mounting frame 2 reaches between the No. 1 roller shutter 3 and the No. 2 roller shutter 3, and the No. 1 roller shutter 3 is placed on the unloading area 7 between the No. 1 roller shutter 3 and the No. 2 roller shutter 3 by the unloading assembly 5, then the mounting frame 2 reaches below the No. 2 roller shutter 3, and the No. 2 roller shutter 3 is made to fall on the mounting frame 2 by pushing the stop rod 64 to move in the same way, and after the measurement of the No. 2 roller shutter 3 is completed, the No. 3 roller shutter 3 is measured in the same way, and so on, until the measurement of all the roller shutters 3 in the box body 61 is completed, after the measurement is completed, the cold room is opened, the roller shutter 3 measured on the unloading area 7 is taken out, and a new roller shutter 3 to be measured is installed on the box body 61 and the mounting frame 2. The measurement is continuously carried out.
