[0028] Two implementation modes of the present application are described in detail below with reference to the accompanying drawings.

[0029] The first implementation method:

[0030] Figure 1-8 The invention shows a thermal insulation testing device for fabrics used for air conditioning, comprising a holding frame 1, wherein an upper heat exchange cylinder 2 and a lower heat exchange cylinder 3 which are arranged opposite to each other and have the same structure are arranged on the front side of the holding frame 1, and a clamping mechanism 5 which drives the upper heat exchange cylinder 2 and the lower heat exchange cylinder 3 to move toward or away from each other is connected to the upper heat exchange cylinder 2 and the lower heat exchange cylinder 3, and the clamping mechanism 5 drives the upper heat exchange cylinder 2 and the lower heat exchange cylinder 3 to clamp or release the fabric body 4; the upper heat exchange cylinder 2 and the lower heat exchange cylinder 3 are connected to the same cold and heat source supply pump 6 through different connecting pipes 18, and the cold and heat source supply pump 6 injects hot air flow and cold air flow into the upper heat exchange cylinder 2 and the lower heat exchange cylinder 3 respectively;

[0031] The upper heat exchange cylinder 2 includes a cylinder 8, which is penetrated by a guide tube 9 vertically slidably connected thereto, a piston disk 10 slidably abutting against the inner wall of the cylinder 8 is fixedly connected to the bottom of the guide tube 9, and the piston disk 10 is penetrated by a first temperature sensor 11 for detecting the temperature of the cavity outside the cylinder 8 located at the piston disk 10, and a second temperature sensor is arranged in the lower heat exchange cylinder 3; a connecting tube 18 is connected to the cavity outside the piston disk 10 through the guide tube 9, and a pair of electromagnetic valves 12 are arranged on opposite opening sides of the cylinder 8;

[0032] The cold and hot source supply pump 6 includes a columnar pump body 19, in the middle of which is nested a semiconductor refrigeration sheet 20 that divides its inner cavity into two independent cavities, the two independent cavities are respectively connected to one of a pair of connecting pipes 18, and a pair of axial flow fans 21 arranged in a mirrored manner are provided on both sides of the semiconductor refrigeration sheet 20. The clamping mechanism 5, the first temperature sensor 11, the second temperature sensor, the semiconductor refrigeration sheet 20 and the pair of axial flow fans 21 are all electrically connected to the controller 7.

[0033] Specifically, the operation method of this application includes the following steps:

[0034] Step 1, preheating and precooling before detection; start the semiconductor refrigeration plate 20 and a pair of axial flow fans 21 through the controller 7, the heating surface of the semiconductor refrigeration plate 20 located in the independent cavity on one side heats the gas in the independent cavity, in the connecting pipe 18 connected thereto, in the guide pipe 9, and in the cavity between the piston disk 10 and the solenoid valve 12 of the cylinder 8, and realizes rapid heat exchange of the airflow through the axial flow fan 21; similarly, the cooling surface of the semiconductor refrigeration plate 20 located in the independent cavity on the other side cools the gas in the independent cavity, in the connecting pipe 18 connected thereto, in the guide pipe 9, and in the cavity between the piston disk 10 and the solenoid valve 12 of the cylinder 8; then, the temperature in the upper heat exchange tube 2 is detected by the first temperature sensor 11, and the temperature in the lower heat exchange tube 3 is monitored by the second temperature sensor, until the temperature difference of the airflow in the upper heat exchange tube 2 and the lower heat exchange tube 3 reaches the set temperature difference threshold, and then the semiconductor refrigeration plate 20 and the pair of axial flow fans 21 are turned off;

[0035] Step 2: Clamp the fabric; by holding the holding frame 1, the upper heat exchange tube 2 and the lower heat exchange tube 3 are placed on both sides of the fabric body 4 to be tested, and the clamping mechanism 5 is started by the controller 7, and the clamping mechanism 5 drives the upper heat exchange tube 2 and the lower heat exchange tube 3 to move toward each other to clamp the fabric body 4;

[0036] Step three, detecting the heat preservation performance; a pair of solenoid valves 12 on opposite sides of the upper heat exchange tube 2 and the lower heat exchange tube 3 are activated by the controller 7, and the hot air flow and the cold air flow in the upper heat exchange tube 2 and the lower heat exchange tube 3 are contacted and heat exchanged through the fabric body 4;

[0037] Step 4, calculating the thermal resistance value, and calculating the heat flow per unit area of ​​the fabric body 4 within the set time according to the temperature change difference between the first temperature sensor 11 and the second temperature sensor within the set time.

[0038] Compared with the traditional air-conditioning quilt thermal insulation detection equipment, the present invention has the advantages of high integration and small volume by installing an upper heat exchange tube 2 and a lower heat exchange tube 3 installed on a holding frame 1 and arranged in an upper and lower pair, a clamping mechanism 5 connected to the two, and a connected cold and heat source supply pump 6, so that the thermal insulation detection equipment can achieve on-site non-destructive sampling and detection of air-conditioning quilt fabrics; in addition, through the semiconductor refrigeration plate 20, the axial flow fan 21 and the solenoid valve 12, it is convenient to synchronously supply the cold and heat sources to the upper heat exchange tube 2 and the lower heat exchange tube 3, so as to achieve energy-saving and stable supply of cold and heat sources, and the airflow is heated, cooled and circulated in a closed space, so as to reduce heat exchange with the external environment and improve detection accuracy.

[0039] See also Figure 1 The holding frame 1 is a horizontal U-shaped structure, and a holding handle is fixedly connected to the side away from the opening end. The controller 7 is installed on the holding frame 1 at the side of the holding handle, and the controller 7 is a PLC controller with a display screen.

[0040] Specifically, it is convenient to carry and operate the thermal insulation detection equipment, and it is also convenient to view the temperature change and heat flow calculation results through the display screen.

[0041] See also Figure 6 The cylinder 8 is a vertical cylindrical structure, the piston disc 10 is a disc-shaped structure with a columnar cavity at the upper end, a sealing ring is nested on the circumferential side wall of the piston disc 10 and abuts against the inner wall of the cylinder 8, the first temperature sensor 11 is installed in the columnar cavity, and the cylinder 8 is provided with a vent hole 802 connected to its inner cavity, and the vent hole 802 is located on the side of the piston disc 10 facing the guide tube 9.

[0042] Specifically, the sealing effect of the piston disc 10 on the airflow inside the cylinder 8 is improved, and the stability of the cylinder 8 moving up and down is improved.

[0043] See also Figure 6 A plurality of concentrically arranged and staggered raised rings 801 are provided on the side walls of the opposite sides of a pair of cylinder bodies 8, and the cross-section of the raised rings 801 is triangular or semicircular.

[0044] Specifically, when a pair of cylinders 8 of the upper heat exchange cylinder 2 and the lower heat exchange cylinder 3 clamp the fabric body 4, the concentric and staggered raised rings 801 perform multi-layer and staggered extrusion sealing on the fabric body 4, reducing heat loss from the clamping position of the fabric body 4 and improving the accuracy of detection.

[0045] See also Figure 6A pressure sensor 24 is embedded in the side wall of the clamping side of one of the cylinders 8 , and the pressure sensor 24 is electrically connected to the controller 7 .

[0046] Specifically, it is convenient to accurately control the clamping pressure of the upper heat exchange tube 2 and the lower heat exchange tube 3 on the fabric body 4, thereby improving the sealing effect.

[0047] See also Figure 6 The solenoid valve 12 is a disc-shaped structure and has a ventilation groove running vertically through it on its central radial line. A valve core 13 is installed at the ventilation groove. The valve core 13 includes a valve core roller nested in the ventilation groove and equipped with a permanent magnet at the end thereof, and an electromagnet sleeved on the outer side of the end of the valve core roller and driving it to rotate. The valve core roller has a connecting groove along its length direction that cooperates with the ventilation groove.

[0048] Specifically, when the electromagnet drives the valve core roller to rotate, the connecting groove on the valve core roller rotates from a horizontal state to a vertical state, and the connecting groove connects the upper and lower ends of the ventilation groove, so that the hot air flow or the cold air flow contacts the fabric body 4 through the ventilation groove, thereby realizing the closed heating and cooling of the air flow in the cylinder 8, reducing heat loss and improving the accuracy of detection.

[0049] It should be noted that the cylinder 8, guide tube 9, connecting tube 18 and columnar pump body 19 are all made of insulating materials. During multiple inspections, after completing the inspections in sequence, the heat is preserved by closing the solenoid valve 12 corresponding to the heat source cavity (the heat exchange cavity in the cylinder 8 that is connected to the cavity where the heating surface of the peninsula body refrigeration plate 20 is located). At the same time, the solenoid valve 12 corresponding to the cold source cavity (the heat exchange cavity in the cylinder 8 that is connected to the cavity where the cooling surface of the peninsula body refrigeration plate 20 is located) and the axial flow fan 21 in the columnar pump body 19 connected thereto are opened to discharge the heated gas after heat exchange in the cold source cavity, thereby reducing energy consumption and preheating and precooling preparation time during subsequent refrigeration operations.

[0050] See also Figure 7 The clamping mechanism 5 includes a pair of movable sleeves 14 respectively sleeved on the upper heat exchange tube 2 and the lower heat exchange tube 3. The movable sleeves 14 are slidably connected to a slide frame 15 fixedly connected to the holding frame 1. The slide frame 15 is provided with a bidirectional screw rod 16 threadedly connected to the pair of movable sleeves 14. The end of the bidirectional screw rod 16 is connected to a screw motor 17.

[0051] Specifically, it is convenient to clamp and seal air-conditioning quilt fabrics of different thicknesses.

[0052] Second implementation method:

[0053] Fig. 9 and Fig.10A device for detecting the thermal insulation of fabrics used for processing air conditioners is shown. Based on the first embodiment, a pair of separation covers 22 located on both sides of a semiconductor refrigeration plate 20 and arranged in a mirror image are installed in a cylindrical pump body 19, an air intake channel is formed between the separation cover 22 and the semiconductor refrigeration plate 20, an axial flow fan 21 is installed in the separation cover 22, and the separation cover 22 is connected to an inner tube 23 nested in a connecting pipe 18 and extending to the outside of the piston disk 10 at one end away from the semiconductor refrigeration plate 20.

[0054] Specifically, in the preheating and precooling stages, the airflow generated by the axial flow fan 21 blows toward the separation hood 22, and then is injected into the cylinder 8 through the inner tube 23. The airflow in the cylinder 8 flows back to the independent cavity of the columnar pump body 19 through the gap between the inner tube 23 and the connecting tube 18, and then enters the separation hood 22 again through the air intake channel between the separation hood 22 and the semiconductor refrigeration plate 20, thereby realizing the circulation of the airflow inside the columnar pump body 19, the connecting tube 18, the cylinder 8, and the inner tube 23, accelerating the preheating and precooling operations of the airflow in the closed cavity, improving the preheating and precooling efficiency, reducing the preparation time, and facilitating multiple and multi-position detections of the same batch of air-conditioning quilt fabrics.

[0055] See also Fig. 9 The axial flow fan 21 is fixedly connected to the inner wall of the columnar pump body 19 through a mounting rod that passes through the separation cover 22. The separation cover 22 is a conical cylindrical structure with openings at both ends.

[0056] Specifically, the separation hood 22 and the axial flow fan 21 are supported and fixed, and the airflow is separated and compressed and accelerated by the conical separation hood 22, so as to further improve the circulation speed and reduce the preparation time.

[0057] In this embodiment, the axial flow fan 21 is equipped with a Hall sensor for detecting the rotation speed thereof, and the Hall sensor is electrically connected to the controller 7 .

[0058] Specifically, in the test phase after closing the semiconductor refrigeration plate 20 and opening the solenoid valve 12, when the upper heat exchange tube 2 and the lower heat exchange tube 3 are exchanging heat, the axial flow fan 21 located on the cold end side of the semiconductor refrigeration plate 20 is started and its rotation speed is controlled to simulate the indoor air-conditioning blowing towards the air-conditioned quilt under different wind speed conditions to detect the thermal insulation performance of the air-conditioned quilt fabric.

[0059] In view of current practical needs, the above-mentioned implementation mode adopted in this application is not limited to the scope of protection. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the scope of protection of the present invention.
