Description

Technical Field

[0001] The utility model relates to the technical field of cold storage heat preservation and pressure regulation, in particular to a civil cold storage heat preservation balance system. Background Art

[0002] In gas fire extinguishing systems and similar occasions that require pressure balance regulation, the existing pressure relief devices have been widely used for their simple structure and convenient operation. Such devices usually include a fixed louver and an overhanging and openable pressure relief window sash, and the arrangement direction of the louver is used to deal with the possible increased pressure side. In the conventional use environment, when the pressure on both sides of the device remains balanced or the difference is small, the pressure relief window sash remains closed by its own gravity, effectively maintaining the airtightness of the system. Once a pressure relief situation occurs, such as a sharp increase in pressure on one side, this pressure will overcome the self-weight of the window sash, causing it to automatically turn up and open, thus achieving rapid pressure relief and protecting the safety of the system.

[0003] However, when such pressure relief devices are directly applied to occasions such as cold storage that require strict temperature control and airtightness requirements, their limitations become particularly prominent. First of all, the inside of the cold storage needs to maintain a very low temperature to store goods, which requires that all openings communicating with the outside world, including the pressure relief device, must have good airtight performance in the closed state. However, in the prior art, it is difficult to ensure perfect airtightness when the overhanging pressure relief window sash is in the natural hanging state, which will cause continuous leakage of cold energy, increase energy consumption and affect the operation efficiency of the cold storage. Secondly, the temperature difference between the inside and outside of the cold storage is huge, and such pressure relief devices do not design corresponding heat preservation measures for the special environment of the cold storage. Long-term application on the cold storage will have a cold bridge effect, resulting in the pressure relief window sash being unable to open smoothly due to freezing, thus losing its pressure relief function in case of emergency.

[0004] In summary, although the traditional pressure relief devices perform well in the conventional environment, in special occasions such as cold storage that require strict temperature control and airtightness, their existing deficiencies and limitations seriously restrict their application effects. Therefore, developing a special pressure relief device that can not only meet the pressure balance requirements of the cold storage but also effectively prevent cold energy leakage and cold bridge phenomena has become an urgent technical problem to be solved.

The heat-insulating balance window includes a pressure relief heat-insulating balance window arranged on the first ventilation and pressure regulating tunnel and a pressure boosting heat-insulating balance window arranged on the second ventilation and pressure regulating tunnel;

[0018] Wherein, the pressure relief heat-insulating balance window opens towards the outer side of the cold storage heat-insulating wall and is used for adjusting the internal and external pressures of the cold storage when the cold storage heats up; the pressure boosting heat-insulating balance window opens towards the inner side of the cold storage heat-insulating wall and is used for adjusting the internal and external pressures of the cold storage when the cold storage cools down.

Detailed implementation manners

[0034] To make the objectives, technical solutions and advantages of the present invention clearer, the technical solutions in the present invention will be clearly and completely described below with reference to the accompanying drawings in the present invention. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present invention without making creative efforts fall within the scope of protection of the present invention.

[0035] Please refer to Figures 1-6, the present utility model provides a civil engineering type cold storage thermal insulation balance system, which includes a cold storage thermal insulation wall 1 and a thermal insulation balance window. The cold storage thermal insulation wall 1 includes a thermal insulation wall and a civil engineering wall, and the civil engineering wall is located outside the thermal insulation wall. A ventilation pressure regulating hole is provided on the cold storage thermal insulation wall 1, which sequentially penetrates through the thermal insulation wall and the civil engineering wall. The thermal insulation balance window is arranged on the ventilation pressure regulating hole and includes a thermal insulation window sash and a thermal insulation window edge. The thermal insulation window edge is sealed on the ventilation pressure regulating hole. The part of the thermal insulation window edge used for fitting with the thermal insulation window sash to achieve the closing of the thermal insulation balance window is the joint part. The peripheral side walls of the joint part are all arranged at a preset inclination angle with respect to the direction perpendicular to the cold storage thermal insulation wall (that is, the peripheral side walls of the joint part are all inclined planes). The thermal insulation window sash is rotatably connected to the thermal insulation window edge and opens towards the low-pressure side of the cold storage thermal insulation wall 1, and is used to adjust the internal and external pressures of the cold storage when the cold storage is heated or cooled.

[0036] Of course, the part of the thermal insulation window edge corresponding to the inside of the ventilation pressure regulating hole and other than the joint part can also be designed as an inclined plane according to actual situations. The specific inclination can be set according to actual situations and is not limited here.

[0037] Among them, the thermal insulation window sash has a thermal insulation inner core, which can be made of a whole piece of closed-cell thermal insulation material and has a good thermal insulation effect. Its surface can be coated with a metal panel that is not easily rusted or a high-strength plastic panel for protection. The peripheral side walls of the thermal insulation window sash respectively match the inclination of the peripheral side walls of the joint part.

[0038] The thermal insulation balance window is fixed on the cold storage thermal insulation wall 1 in an upper-hung manner. During the temperature rise and fall of the cold storage, when the pressure difference between the inside and outside of the cold storage reaches a preset value, the thermal insulation balance window can be started to adjust the internal and external air pressures of the cold storage; when the pressure difference between the inside and outside of the cold storage is less than the preset value, the thermal insulation balance window will naturally droop and close due to its own gravity. Among them, the specific preset value can be determined according to factors such as the size and self-weight of the thermal insulation window sash, so that when the pressure difference between the inside and outside of the cold storage reaches this preset value, the thermal insulation window sash can be lifted by the air under the action of the pressure difference (that is, opened).

[0039] Among them, when the thermal insulation window sash is in the closed state, the thermal insulation window sash is attached to the thermal insulation window edge (or ventilation pressure regulating hole) at a preset inclination angle (that is, the thermal insulation window sash and the cold storage thermal insulation wall are at a preset inclination angle). That is to say, when the thermal insulation window sash is completely closed, the thermal insulation window sash is also arranged at a certain inclination angle with respect to the cold storage thermal insulation wall. Compared with the design method in which the thermal insulation window sash can be completely closed only at an angle parallel to the cold storage thermal insulation wall, the way that the thermal insulation window sash and the thermal insulation window edge contact with each other by an inclined plane in this application can reduce the gap formed at the hole when the window sash naturally droops and reduce the cold loss when the thermal insulation balance window is closed.

[0040] Please refer to Figures 1 to 6, in an embodiment of the present application, in order to better balance the pressure difference inside and outside the cold storage, pressure relief and pressure boosting insulation balance window sashes are respectively installed at the upper and lower parts of the cold storage insulation wall 1. Specifically, the ventilation and pressure regulating tunnel includes a first ventilation and pressure regulating tunnel 2 located at the upper part of the cold storage insulation wall 1 and a second ventilation and pressure regulating tunnel 3 located at the lower part of the cold storage insulation wall 1. The pressure relief and pressure boosting insulation balance window includes a pressure relief insulation balance window 100 arranged on the first ventilation and pressure regulating tunnel 2 and a pressure boosting insulation balance window 200 arranged on the second ventilation and pressure regulating tunnel 3. Among them, the pressure relief insulation balance window 100 opens towards the outside of the cold storage insulation wall 1 and is used to adjust the internal and external pressures of the cold storage when the cold storage is warming up. The pressure boosting insulation balance window 200 opens towards the inside of the cold storage insulation wall 1 and is used to adjust the internal and external pressures of the cold storage when the cold storage is cooling down.

[0041] Among them, the cold storage in this embodiment is a civil engineering cold storage, including an insulation wall and a civil engineering wall. The insulation wall includes a wall panel 101 and a wall insulation layer 102. The wall insulation layer 102 is sandwiched between the wall panel 101 and the civil engineering wall, so as to achieve the insulation of the cold storage. Among them, the wall insulation layer 102 penetrates through the ventilation and pressure regulating tunnel along the extension direction of the ventilation and pressure regulating tunnel. The civil engineering wall includes a plaster layer 103 and a civil engineering layer 104, and the civil engineering layer 104 is encapsulated in the plaster layer 103.

[0042] Before installing the pressure relief insulation balance window 100 and the pressure boosting insulation balance window 200, first ventilation and pressure regulating tunnel 2 and second ventilation and pressure regulating tunnel 3 corresponding to the sizes of the pressure relief insulation balance window 100 and the pressure boosting insulation balance window 200 respectively need to be opened on the cold storage insulation wall 1, and then the pressure relief insulation balance window 100 and the pressure boosting insulation balance window 200 are respectively installed on the first ventilation and pressure regulating tunnel 2 and the second ventilation and pressure regulating tunnel 3. Among them, the height of the pressure relief insulation balance window 100 is generally kept consistent with that of the cold air blower inside the cold storage and is fixed on the outside of the cold storage insulation wall 1. The installation height of the pressure boosting insulation balance window 200 should be convenient for ordinary people to operate and is fixed on the inside of the cold storage insulation wall 1.

[0043] Specifically as Figure 2 shown, the pressure relief insulation balance window 100 includes a first insulation window sash 4 and a first insulation window edge wrap 19. The first insulation window sash 4 is rotationally connected to the top position of the first insulation window edge wrap 19 through a first rotating member 6 (i.e., fixed in a top-hung manner). When the cold storage is warming up, the internal pressure of the cold storage is higher than the external pressure. When the pressure difference between the inside and outside of the cold storage reaches a certain value, at this time, the first insulation window sash 4 is automatically lifted by the air under the action of the pressure difference and opens towards the outside; since the opening direction of the pressure boosting insulation balance window is opposite to that of the pressure relief insulation balance window 100, therefore, at this time, the pressure boosting insulation balance window is in a natural closed state. Thus, the purpose of adjusting the internal and external pressures of the cold storage when the cold storage is warming up is achieved.

[0044] As Figure 5As shown in the figure, the pressure-boosting heat-insulating balance window 200 includes a second heat-insulating window sash 5 and a second heat-insulating window edge 20. The second heat-insulating window sash 5 is rotatably connected to the top position of the second heat-insulating window edge 20 through a second rotating member 7 (i.e., fixed in a casement way). When the cold storage cools down, the external pressure of the cold storage is higher than the internal pressure. When the pressure difference between the inside and outside of the cold storage reaches a certain value, at this time, the second heat-insulating window sash 5 is automatically pushed up by the air under the action of the pressure difference and opens inward; since the opening direction of the pressure-boosting heat-insulating balance window 200 is opposite to that of the pressure-relieving heat-insulating balance window, therefore, at this time, the pressure-relieving heat-insulating balance window is in a natural closed state. Thus, the purpose of adjusting the pressure inside and outside the cold storage when the cold storage cools down is achieved.

[0045] In one embodiment, both the first rotating member 6 and the second rotating member 7 can be hinge-type connecting members, and no limitation is made here.

[0046] Among them, both the pressure-relieving heat-insulating balance window 100 and the pressure-boosting heat-insulating balance window 200 have heat-insulating cores, and the outer surfaces of the heat-insulating cores are fine and flat. When the pressure-relieving heat-insulating balance window 100 and / or the pressure-boosting heat-insulating balance window 200 is closed, the window joint part will be as airtight as possible to reduce the cold loss generated when the heat-insulating balance window is closed.

[0047] Specifically, please refer to Figure 1 and Figure 2 , before installing the pressure-relieving heat-insulating balance window 100, a first ventilation and pressure-regulating hole 2 should be left on the cold storage heat-insulating wall 1, and corresponding slopes should be made on the side walls of the first ventilation and pressure-regulating hole 2 according to the shape requirements of the pressure-relieving heat-insulating balance window 100. It can be understood that making corresponding slopes on the side walls means that the slopes of the side walls of the first ventilation and pressure-regulating hole 2 are respectively the same as the slopes of the side walls of the first heat-insulating window edge 19, so that the side walls of the first heat-insulating window edge 19 can better fit on the first ventilation and pressure-regulating hole 2. The first heat-insulating window edge 19 is used to protect the first ventilation and pressure-regulating hole 2 and provide heat insulation at the window.

[0048] Among them, the outside of the cold storage heat-insulating wall 1 is the opening side of the first heat-insulating window sash 4, and the opening of the first ventilation and pressure-regulating hole 2 close to the opening side of the first heat-insulating window sash 4 is larger than the opening far from the opening side of the first heat-insulating window sash 4. And, the opening of the first ventilation and pressure-regulating hole 2 is inclined downward at a certain angle in the direction conducive to the flow of condensed water from top to bottom.

[0049] Specifically, the first heat-insulating window edge 19 includes a first upper sealing plate 8, two first side sealing plates 9 and a first lower sealing plate 10, and also includes a first additional heat-insulating layer 12. Among them, a first upper sealing plate 8, two first side sealing plates 9 and a first lower sealing plate 10 are respectively encapsulated on the upper side wall, the left and right side walls and the lower side wall of the first ventilation and pressure-regulating hole 2, and the four enclose to form a hole sealing plate to encapsulate the first ventilation and pressure-regulating hole 2.

[0050] Among them, the slope of the first heat preservation window edging 19 corresponding to the side wall part of the first ventilation and pressure regulating tunnel 2 is consistent with the slope of the corresponding side wall of the first ventilation and pressure regulating tunnel 2.

[0051] Furthermore, the first upper sealing plate 8, the two first side sealing plates 9 and the first lower sealing plate 10 are all U-shaped structures, which can wrap and seal both ends of the first ventilation and pressure regulating tunnel 2.

[0052] Furthermore, as shown in Figures 1-3 , the widths of the two first side sealing plates 9 and the first lower sealing plate 10 in the thickness direction of the cold storage heat preservation wall 1 are both greater than the thickness of the cold storage heat preservation wall 1. Three protruding civil engineering wall overhangs 11 are respectively formed on the two side edges and the bottom edge of the civil engineering wall near the outer edge of the opening of the first ventilation and pressure regulating tunnel 2. The two first side sealing plates 9 and the first lower sealing plate 10 are respectively attached to the outer edges of the three civil engineering wall overhangs 11, and the three civil engineering wall overhangs 11, the corresponding opening sealing plates and the heat preservation wall enclose a closed cavity, and the first additional heat preservation layer 12 is filled in the closed cavity, thereby improving the heat preservation effect of the cold storage.

[0053] Among them, for the convenience of matching and connecting with the civil engineering wall, the first heat preservation window edging 19 is made of fireproof rubber plates with a certain thickness or bamboo glue plates with fireproof performance and other plates. The surface can be attached with stainless steel plates or low-temperature resistant hard plastic plates, or directly coated with high-quality waterproof and antifreeze paint. When using surface attached plates, the surface attached plates need to be extended downward by 1 cm on both the inner and outer sides of the lower sealing plate of the opening to form the first lower sealing plate drip 21, which is used as the drip when the condensed water flows downward, so as to reduce the phenomenon of the civil engineering wall surface being watered. When using the direct painting method, grooves can be made on the lower bottom surfaces of both the inner and outer sides of the first lower sealing plate to form the first lower sealing plate drip 21.

[0054] Among them, the first heat preservation window sash 4 includes a first heat preservation sash outer plate 401, a first heat preservation inner core 402 and a first handle 403. The first heat preservation inner core 402 is encapsulated inside the first heat preservation sash outer plate 401, and the first handle 403 is arranged outside the first heat preservation sash outer plate 401 and is located at the bottom of the pressure relief and heat preservation balance window. The first heat preservation window sash 4 can also be opened or closed manually through the first handle 403.

[0055] The peripheral side walls of the first heat preservation window sash 4 are all designed with inclined surfaces, and the slopes of the peripheral side walls of the first heat preservation window sash 4 respectively match the slopes of the peripheral side walls of the joint part of the first heat preservation window edging 19, so that the window sash area of the first heat preservation window sash 4 facing the first ventilation and pressure regulating tunnel 2 is smaller than the window sash area of the side facing away from the first ventilation and pressure regulating tunnel 2.

[0056] To ensure the airtightness and heat preservation performance of the first heat preservation window sash 4 after it naturally hangs down and closes, a thickened heat preservation design is adopted for the bottom edge and both side edges outside the first ventilation and pressure regulating tunnel 2, that is, the widths of the first lower sealing plate 10 and the two first side sealing plates 9 are widened, and the first additional heat preservation layer 12 is filled. Thereby, the gap between the first heat preservation window sash 4 and the first ventilation and pressure regulating tunnel 2 when the first heat preservation window sash 4 naturally hangs down can be reduced, the heat preservation performance can be enhanced, and the cold loss when the pressure relief and heat preservation balance window closes can be reduced.

[0057] As Figure 3 shown, further, in order to better fit the angle after the first heat preservation window sash 4 closes, the thickness of the first heat preservation window edge 19 corresponding to the left and right side edges of the opening of the first ventilation and pressure regulating tunnel 2 gradually increases from the top to the bottom of the first ventilation and pressure regulating tunnel 2, and is connected to the thickness of the first heat preservation window edge 19 corresponding to the bottom edge of the opening of the first ventilation and pressure regulating tunnel 2. In this way, after the first heat preservation window sash 4 closes at a preset slope, each side wall thereof can better fit onto the joint of the first heat preservation window edge 19, and the gap between the first heat preservation window sash 4 and the first ventilation and pressure regulating tunnel opening or the joint when the first heat preservation window sash 4 naturally hangs down can be minimized.

[0058] In one embodiment, a first insect-proof and air-permeable fan is provided at one end of the first ventilation and pressure regulating tunnel 2 away from the pressure relief and heat preservation balance window. The first insect-proof and air-permeable fan can be a device such as a shutter, a screen window, or a shutter with an additional steel wire mesh, etc., to prevent insects or small animals from entering the tunnel opening. Of course, in other embodiments, the first insect-proof and air-permeable fan may not be provided because the air in the cold storage flows outwards through the first ventilation and pressure regulating tunnel 2, and it is not easy for insects or small animals to enter the tunnel opening due to the influence of air resistance.

[0059] Please refer to Figure 4 and Figure 5 Before installing the pressurized heat preservation balance window 200, a second ventilation and pressure regulating tunnel 3 should be left on the cold storage heat preservation wall 1, and corresponding slopes should be made on the side walls of the second ventilation and pressure regulating tunnel 3 according to the requirements of the shape of the pressurized heat preservation window sash. It can be understood that making corresponding slopes on the side walls means that the slopes of the side walls of the second ventilation and pressure regulating tunnel 3 are set to be the same as the slopes of the side walls of the second heat preservation window edge 20. In this way, the side walls of the second heat preservation window edge 20 can better fit onto the second ventilation and pressure regulating tunnel 3, and the second heat preservation window edge 20 is used to protect the second ventilation and pressure regulating tunnel 3 and provide heat preservation at the window.

[0060] Among them, the inner side of the cold storage heat preservation wall 1 is the opening side of the second heat preservation window sash 5, and the opening of the second ventilation and pressure regulating tunnel 3 near the opening side of the second heat preservation window sash 5 is larger than the opening away from the opening side of the second heat preservation window sash 5. And, the opening of the second ventilation and pressure regulating tunnel 3 slopes downward at a certain angle in the direction conducive to the flow of condensed water from top to bottom.

[0061] Specifically, the second heat preservation window edge 20 includes a second upper edge sealing plate 13, two second side edge sealing plates 14 and a second lower edge sealing plate 15, and also includes two additional outer edge sealing plates 16 and a second additional heat preservation layer 17. Among them, a second upper edge sealing plate 13, two second side edge sealing plates 14 and a second lower edge sealing plate 15 are respectively encapsulated on the upper side wall, the left and right side walls and the lower side wall of the second ventilation and pressure regulating tunnel 3, and the four enclose to form an opening edge sealing plate to encapsulate the second ventilation and pressure regulating tunnel 3.

[0062] Among them, the slope of the second heat preservation window edge 20 corresponding to the side wall part of the second ventilation and pressure regulating tunnel 3 is the same as the slope of the corresponding side wall of the second ventilation and pressure regulating tunnel 3.

[0063] Furthermore, the second upper edge sealing plate 13, two second side edge sealing plates 14 and the second lower edge sealing plate 15 are all of U-shaped structures, and can perform edge sealing encapsulation on both ends of the second ventilation and pressure regulating tunnel 3.

[0064] Furthermore, the widths of the two second side edge sealing plates 14 and the second lower edge sealing plate 15 in the thickness direction of the cold storage heat preservation wall 1 are both greater than the thickness of the cold storage heat preservation wall 1, and the two additional outer edge sealing plates 16 are respectively spliced with the two second side edge sealing plates 14. An inner protection wall 105 is provided at the bottom edge inside the opening of the second ventilation and pressure regulating tunnel 3. The two additional outer edge sealing plates 16, together with the inner protection wall 105, the corresponding opening edge sealing plate and the heat preservation wall enclose to form a closed cavity, and the second additional heat preservation layer 17 is filled in the closed cavity, thereby improving the heat preservation effect of the cold storage.

[0065] Among them, for the convenience of matching and connecting with the civil engineering wall, the second heat preservation window edge 20 is made of fireproof rubber plates with a certain thickness or bamboo glue plates with fireproof performance and other plates, and a stainless steel plate or a low-temperature resistant hard plastic plate can be attached to the surface, or high-quality waterproof and antifreeze paint can be directly applied. When using the surface attached plate, the surface attached plate needs to be extended downward by 1 cm on both the inner and outer sides of the lower edge sealing plate of the opening to form the second lower edge sealing plate drip 22, which is used as the drip when the condensed water flows downward, so as to reduce the phenomenon of the civil engineering wall surface being watered. When using the direct painting method, grooves can be made on the lower bottom surfaces of both the inner and outer sides of the second lower edge sealing plate to form the second lower edge sealing plate drip 22.

[0066] Among them, the second heat preservation window sash 5 includes a second heat preservation sash outer wrapping plate 501, a second heat preservation inner core 502 and a second handle 503. The second heat preservation inner core 502 is encapsulated inside the second heat preservation sash outer wrapping plate 501, and the second handle 503 is arranged outside the second heat preservation sash outer wrapping plate 501 and is located at the bottom of the pressurized heat preservation balance window sash. The second heat preservation window sash 5 can also be opened or closed manually through the second handle 503.

[0067] The peripheral side walls of the second heat-insulating window sash 5 are all designed with inclined surfaces, and the slopes of the peripheral side walls of the second heat-insulating window sash 5 respectively match the slopes of the peripheral side walls of the joint part of the second heat-insulating window edge 20, so that the window sash area of the second heat-insulating window sash 5 facing the second ventilation and pressure regulating tunnel 3 is smaller than the window sash area on the side facing away from the second ventilation and pressure regulating tunnel 3.

[0068] Combined Figure 5 with Figure 6 As shown, in order to ensure the airtightness and heat preservation performance after the second heat-insulating window sash 5 naturally droops and closes, a thickening and heat preservation design is adopted for the bottom edge and both side edges of the second ventilation and pressure regulating tunnel 3, that is, the widths of the second lower sealing plate 15 and the two second side sealing plates 14 are widened, and the second additional heat-insulating layer 17 is filled. Thereby, the gap between the pressure-increasing and heat-preserving balance window sash and the second ventilation and pressure regulating tunnel 3 when it naturally droops can be reduced, the heat preservation performance can be enhanced, and the cold loss when the second heat-insulating window sash 5 closes can be reduced.

[0069] As Figure 6 shown, further, in order to better fit the angle after the second heat-insulating window sash 5 closes, the thickness of the second heat-insulating window edge 20 corresponding to the left and right side edges of the opening of the second ventilation and pressure regulating tunnel 3 gradually increases from the top to the bottom of the second ventilation and pressure regulating tunnel 3, and is connected to the thickness of the second heat-insulating window edge 20 corresponding to the bottom edge of the opening of the second ventilation and pressure regulating tunnel 3. In this way, after the second heat-insulating window sash 5 closes at a preset slope, each side wall thereof can better fit onto the joint part of the second heat-insulating window edge 20, and the gap between the second heat-insulating window sash 5 and the opening or joint part of the second ventilation and pressure regulating tunnel when it naturally droops can be minimized.

[0070] Among them, an inner protection wall 105 is provided below the thickening position of the bottom edge of the second ventilation and pressure regulating tunnel 3 of the second heat-insulating window edge 20, which can provide good support for the thickening structure.

[0071] In one embodiment, a second insect-proof and breathable fan 18 is provided at one end of the second ventilation and pressure regulating tunnel 3 away from the pressure-increasing and heat-preserving balance window. The second insect-proof and breathable fan 18 includes an openable window frame 181 and an insect-proof and breathable net 182, and the insect-proof and breathable net 182 is installed on the openable window frame 181. Exemplarily, the second insect-proof and breathable fan 18 can be a device such as a shutter, a screen window or a shutter with an additional steel mesh, to prevent insects or small animals from entering the opening. Of course, in other embodiments, the second insect-proof and breathable fan 18 may not be provided, and there is no limitation here.

[0072] In the above embodiments, both the first heat-insulating inner core 402 and the second heat-insulating inner core 502 are made of heat-insulating and heat-preserving materials with excellent performance, and the first heat-insulating fan outer plate 401, the second heat-insulating fan outer plate 501, the first handle 403 and the second handle 503 are all made of stainless steel or low-temperature resistant rigid plastic.

[0073] The civil construction type cold storage thermal insulation balance system of the present utility model designs the four side walls of the edge wrapping of the thermal insulation window as beveled openings (that is, at least the four side walls at the joint of the edge wrapping of the thermal insulation window are beveled surfaces), and the slopes of the four side walls of the thermal insulation window sash respectively match the slopes of the four side walls at the joint of the edge wrapping of the thermal insulation window, so that when the thermal insulation window sash is closed, it can be attached to the edge wrapping of the thermal insulation window with a preset slope. Compared with the straight-edge window edge wrapping (that is, each side wall of the window edge wrapping is perpendicular to the wall direction), after the thermal insulation balance window of the present utility model is closed, the thermal insulation window sash is attached to the edge wrapping of the thermal insulation window (or ventilation pressure regulating hole) with a preset slope, thereby reducing the gap between the window sash and the ventilation pressure regulating hole when the window sash naturally sags, and reducing the cold loss when the thermal insulation balance window is closed. In addition, the thermal insulation balance window of the present utility model has a thermal insulation inner core, which plays a certain thermal insulation role and can effectively prevent cold leakage and cold bridge phenomenon.

[0074] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present utility model and are not intended to limit them; although the present utility model has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present utility model.
