Abstract
Description
Technical Field
[0001] This invention relates to the field of building envelope technology, and more specifically, to an ultra-low energy consumption building envelope structure and construction method. Background Technology
[0002] Energy conservation is a key technical indicator of current concern. In the construction industry, energy conservation refers to achieving internal cooling with lower energy consumption in summer and internal heating with lower energy consumption in winter, while reducing the amount of external heat entering the building in summer and the amount of heat loss from the building in winter. Building energy conservation is mainly achieved through the building envelope, which includes walls, doors, windows, and floors. Walls are insulated to reduce energy consumption, while windows use multi-layered glass for insulation.
[0003] Doors are the main points of heat exchange between the inside and outside of buildings, especially in shopping malls, where doors open and close frequently, resulting in high energy consumption. Currently, shopping malls mainly adopt two measures to reduce energy consumption:
[0004] 1. Installing automatic double doors at the entrance, which use sensors to identify people and open or close the doors accordingly, but this method can only be fully opened or fully closed, and cannot adjust the opening size of the doors according to the flow of people, resulting in a large amount of energy loss.
[0005] 2. Installing a revolving door at the entrance reduces the airflow between the inside and outside, thus affecting passage efficiency.
[0006] Therefore, a new solution is needed to address this problem. Summary of the Invention
[0007] In view of the shortcomings of the existing technology, the purpose of this invention is to provide an ultra-low energy consumption building envelope structure and construction method, which can effectively reduce the loss of indoor and outdoor cold or heat and achieve ultra-low energy consumption.
[0008] The above-mentioned technical objective of the present invention is achieved through the following technical solution: an ultra-low energy consumption building envelope, including a door frame and an electric double door installed inside the door frame, and also including a controller and a gravity detection component installed on the ground outside the door frame for detecting the weight of personnel. The gravity detection component and the electric double door are electrically connected to the controller. The electric double door has multiple opening widths. The controller is adapted to control the opening and closing of the electric double door to an opening width that is adapted to the weight of personnel. An insulated door curtain assembly that can close the opening of the electric double door is provided on the interior side of the door frame.
[0009] In one embodiment, the electric double door includes a track fixedly connected to the top of the door frame, two door panels slidably connected to the track, and a drive unit for driving the two door panels to open and close.
[0010] In one embodiment, an anti-pinch sensor is provided between the two door panels, and the anti-pinch sensor is electrically connected to the controller.
[0011] In one embodiment, the gravity detection assembly includes a base plate fixed to the ground outside the door frame, a cover plate disposed above the base plate, and gravity sensors fixedly connected between the base plate and the cover plate, wherein a plurality of gravity sensors are arranged along the length direction of the base plate and the cover plate.
[0012] In one embodiment, the cover plate is provided with a downward slope around its perimeter.
[0013] In one embodiment, the insulated door curtain assembly includes a connector and multiple long strips of insulation cotton layers. A frame is fixedly connected to the interior side of the door frame. The insulated door curtain assembly is positioned on the frame directly opposite the electric double door. The electric double door, the frame, and the insulation cotton layers together form a sealed cavity. One side of the connector is fixed to the top of the frame, and the other side of the connector is fixedly connected to the insulation cotton layers. One of the adjacent insulation cotton layers can at least partially overlap the surface of the other insulation cotton layer, located at the overlap position. Electromagnets and metal sheets that can be attracted to the electromagnets are respectively installed at the relative positions of the two insulation cotton layers. Each insulation cotton layer is provided with a proximity sensor on the side near the electric double door to detect whether a person is approaching. The electromagnets and proximity sensors are electrically connected to the controller. The electromagnets are configured to de-energize when a person approaches the target insulation cotton layer, and to energize when no person approaches the target insulation cotton layer, so as to realize the disconnection and adhesion between adjacent insulation cotton layers.
[0014] In one embodiment, the lengths of the electromagnet and the metal sheet are adapted to the length of the insulation layer, and both the electromagnet and the metal sheet are covered with a soft covering layer.
[0015] A construction method for an ultra-low energy building envelope, comprising any of the ultra-low energy building envelopes described above, further comprising the following steps:
[0016] S1. Install the door frame at the target location on the building;
[0017] S2. Install the electric double doors inside the door frame;
[0018] S3. Install the thermal insulation curtain assembly on the door frame located on the indoor side so that the thermal insulation curtain assembly can close the opening of the electric double door;
[0019] S4. Install the gravity detection component on the ground outside the door frame;
[0020] S5. Connect the electric double door, the insulated door curtain assembly, and the gravity detection assembly to the controller via cables.
[0021] In summary, the present invention has the following beneficial effects: By incorporating an electric double door, a gravity detection component, and an insulated door curtain component, the gravity detection component can determine the volume of pedestrian traffic based on the magnitude of gravity values, thereby adjusting the opening width of the electric double door. When pedestrian traffic is low, this avoids the loss of cold or heat caused by a large opening width, thus improving passage efficiency while ensuring low energy consumption. At the same time, the insulated door curtain further reduces energy loss, achieving ultra-low energy consumption. Attached Figure Description

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0028] like Figures 1 to 4As shown, an embodiment of this application provides an ultra-low energy consumption building envelope, including a door frame 1 and an electrically operated double door 2 disposed within the door frame 1. It also includes a controller and a gravity detection component 3 disposed on the ground outside the door frame 1 for detecting the weight of personnel. The gravity detection component 3 and the electrically operated double door 2 are electrically connected to the controller, which may specifically be a PLC controller. The electrically operated double door 2 has multiple opening widths, and the controller is adapted to control the opening and closing of the electrically operated double door 2 to an opening width appropriate to the weight of the personnel. An insulated door curtain assembly 5 is disposed on the interior side of the door frame 1 to close the opening of the electrically operated double door 2.
[0029] It should be noted that the aforementioned various opening widths can be widths that are continuously adjustable in real time, or different widths that open and close according to a certain gradient. The specific adjustment method can be implemented through an algorithm program stored in the controller in existing technology. The specific steps are as follows:
[0030] Step 1: First, obtain the maximum value of the person's gravity at a certain moment using gravity detection component 3;
[0031] Step 2: Delay the maximum value of the obtained personnel gravity value so that the maximum value of the personnel gravity value can be maintained for a period of time within the target duration;
[0032] Step 3: Output the personnel gravity value from Step 2 as a control pulse signal. The control pulse signal controls the electric double door 2 to open to the target opening width. The target opening width is determined according to the personnel gravity value. The larger the personnel gravity value, the larger the target opening width, and vice versa. The opening width is maintained within the target opening width for a period of time to facilitate personnel passage.
[0033] Specifically, if the weight of the person increases or decreases after being held within the target opening width for a period of time, the target opening width will increase or decrease accordingly and will be maintained for a period of time.
[0034] In the above method, by setting up the electric double door 2, the gravity detection component 3 and the heat-insulating curtain component 5, the gravity detection component 3 can determine the amount of people by the magnitude of the gravity value, and then adjust the opening width of the electric double door 2 within the corresponding gradient. When the amount of people is small, it avoids the loss of cold or heat caused by a large opening width, thereby improving passage efficiency while ensuring low energy consumption. At the same time, by setting up the heat-insulating curtain, energy loss can be further reduced, achieving ultra-low energy consumption.
[0035] In this embodiment, the electric double door 2 includes a track 21 fixedly connected to the top of the door frame 1, two door panels 22 slidably connected to the track 21 via rollers 23, and a drive unit (not shown) for driving the two door panels 22 to open and close. Specifically, the drive unit may consist of synchronous pulleys rotatably connected to both ends of the top of the door frame 1, a synchronous belt connected between the two synchronous pulleys, and a servo motor for driving either synchronous pulley to rotate. One door panel 22 is connected to the upper side of the synchronous belt via sheet metal, and the other door panel 22 is connected to the lower side of the synchronous belt via sheet metal. Driven by the servo motor, both door panels 22 can be opened or closed, offering advantages such as simple structure and good operational stability.
[0036] In this embodiment, an anti-pinch sensor is installed between the two door panels 22, and the anti-pinch sensor is electrically connected to the controller. The anti-pinch sensor can be the same type used in elevator doors, which will not be elaborated upon in this embodiment. By using the anti-pinch sensor, the opening and closing of the electric double doors 2 is prioritized based on the sensor. When a person is detected entering, the electric double doors 2 will not continue to close, effectively preventing injury to personnel.
[0037] In this embodiment, the gravity detection component 3 includes a base plate fixed to the ground outside the door frame 1 by expansion screws, a cover plate disposed above the base plate, and gravity sensors fixedly connected between the base plate and the cover plate. Several gravity sensors are arranged along the length of the base plate and the cover plate. The base plate can accommodate multiple people standing in a queue simultaneously, and the weight value of each person is obtained in a manner similar to weighing on an electronic scale.
[0038] In this embodiment, the cover plate is provided with a downward slope around its perimeter. By providing the slope, the slope can be as close to the ground as possible, thereby reducing the chance of people tripping.
[0039] In this embodiment, the insulated door curtain assembly 5 includes a connector 51 and multiple strips of insulation cotton layers 52. A frame 4 is fixedly connected to the interior side of the door frame 1. The insulated door curtain assembly 5 is positioned on the frame 4 directly opposite the electric double door 2. The electric double door 2, the frame 4, and the insulation cotton layers 52 together form a sealed cavity. One side of the connector 51 is fixed to the top of the frame 4, and the other side is fixedly connected to the insulation cotton layers 52. One of the adjacent insulation cotton layers 52 can at least partially overlap the surface of the other insulation cotton layer 52 at the overlap position. Electromagnets 53 and metal sheets that can be attracted to the electromagnets 53 are respectively arranged at the relative positions of the two insulation cotton layers 52. Each insulation cotton layer 52 is provided with a proximity sensor for sensing whether a person is approaching on the side close to the electric double door 2. The electromagnets 53 and the proximity sensors are electrically connected to the controller. The electromagnets 53 are configured to de-energize when a person approaches the target insulation cotton layer 52, and to energize when no person approaches the target insulation cotton layer 52, so as to realize the disconnection and adhesion between adjacent insulation cotton layers 52.
[0040] When the above-mentioned heat-insulating door curtain assembly 5 is working, when the proximity sensor detects that a person is entering, the electromagnet 53 is de-energized, and the two adjacent heat-insulating cotton layers 52 separate. Compared with using ordinary magnets directly, it is not necessary to use a lot of force to separate the heat-insulating cotton layers 52, which makes it easier for people to enter quickly. When no one is approaching, the electromagnet 53 is energized, and the two adjacent heat-insulating cotton layers 52 are attracted and fixed together, which makes it less likely for gaps to appear and helps to reduce the loss of heat or cold.
[0041] In this embodiment, the lengths of the electromagnet 53 and the metal sheet are adapted to the length of the insulation cotton layer 52. Both the electromagnet 53 and the metal sheet are covered with a soft layer. By setting the soft layer, it is not easy to cause scratches to personnel.
[0042] This invention also discloses a construction method for an ultra-low energy consumption building envelope, including any of the ultra-low energy consumption building envelopes described above, and further comprising the following steps:
[0043] S1. Install door frame 1 at the target location on the building;

[0045] S3. Install the thermal insulation curtain assembly 5 on the door frame 1 located on the indoor side, so that the thermal insulation curtain assembly 5 can close the opening of the electric double door 2.

[0047] S5. Connect the electric double door 2, the heat-insulating door curtain assembly 5, and the gravity detection assembly 3 to the controller via cables.
