Description

Technical Field

[0001] This invention relates to the field of intelligent temperature control devices, specifically to an intelligent temperature control device for heat storage in low-carbon buildings. Background Technology

[0002] Low-carbon buildings refer to buildings that reduce the use of fossil fuels, improve energy efficiency, and reduce carbon dioxide emissions throughout their entire lifecycle, from the manufacturing of building materials and equipment to construction and use. Low-carbon buildings typically use solar-powered heating systems. However, the heating capacity of these systems decreases at night, making it impossible to provide continuous and stable heating. Therefore, thermal storage systems are gradually becoming the mainstream heating devices for low-carbon buildings.

[0003] Most thermal storage systems use phase change materials. They are typically heated by solar energy during the day and the heat is stored in the phase change material. When heating is needed, the energy stored in the phase change material is released back into the room, achieving the goal of low-carbon heating.

[0004] When providing heating, it is necessary to consider the actual indoor temperature for temperature control. However, when using phase change materials as energy storage for heating, unstable heating often occurs, with higher temperatures at the beginning and lower temperatures at the end of the heating period.

[0006] Preferably, each pair of the heat replenishment units is symmetrically arranged on both sides of the heat storage chamber, and the two rotating arm assemblies are driven to slide their ends in the arc-shaped channels at two different positions, thereby making the two sub-heat storage units stacked one after the other.

The support rod has one end fixedly connected to the movable plate, and the other end passes through the other end of the rotating arm and is fixedly connected to the support plate.

[0009] Preferably, the end of each of the arc-shaped channels is connected by a first connecting plate; the moving component includes a sliding shaft; the end of the arc-shaped channel near the heat storage chamber is fixedly connected to one end of the sliding shaft, and the other end of the sliding shaft passes through the heat storage chamber and slides in cooperation with the heat storage chamber.

[0015] Beneficial effects of this invention: This invention proposes a low-carbon building thermal storage intelligent temperature control device. This device incorporates multiple supplementary heating units to achieve stable heating. When the end of the rotating arm assembly swings through the arc-shaped channel near the thermal storage chamber, the transmission assembly drives the moving assembly to retract the telescopic guide assembly.

[0016] Furthermore, by controlling the fan to transfer heat, different fan speeds and air volumes also affect the heating temperature. In conjunction with multiple overlapping sub-heat storage units, a wide range of temperature regulation can be achieved, thus realizing the purpose of intelligent temperature control.

[0019] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0020] Example 1 A low-carbon building thermal storage intelligent temperature control device, such as Figure 1-5 As shown, it includes a heat storage chamber 1, a heat exchange tube 3, and a fan assembly.

[0021] like Figure 1 and Figure 5 As shown, Figure 1 Three-dimensional structural diagram of the main heat storage body. Figure 5 This is a front view of the main heat storage unit. The main heat storage unit consists primarily of a heat storage chamber 1 and a storage compartment 6 fixedly installed at the lower end of the heat storage chamber 1. The interior of the heat storage chamber 1 is filled with phase change material 4 as an energy storage component. The heat storage chamber 1 has multiple horizontal air ducts 9, and a fan assembly is located at the back of the heat storage chamber 1, which uses airflow to transport heat along the air ducts 9.

[0022] like Figure 1 As shown, the heat exchange tube 3 is arranged in a tortuous manner inside the heat storage chamber 1; a heat exchange medium flows inside the heat exchange tube 3 and exchanges heat with the phase change material 4. Furthermore, the inlet and outlet of the heat exchange tube 3 are connected to a solar heating device, which heats the heat exchange medium inside the heat exchange tube 3 with solar energy, and then exchanges heat with the phase change material 4.

[0023] Each heat storage unit includes a sub-heat storage unit 5 filled with phase change material 4, and a rotating arm assembly and a telescopic guide assembly mounted on one side of the heat storage chamber 1; the sub-heat storage unit 5 has multiple sub-air ducts; the rotating arm assembly drives its end to extend and retract and swing around an arc; one side of the sub-heat storage unit 5 is rotatably connected to the end of the rotating arm assembly; the telescopic guide assembly includes multiple arc-shaped channels 19 arranged in a front-to-back array with open ends and a moving assembly that drives the arc-shaped channels 19 to extend and retract; the moving assembly cooperates with the rotating arm assembly through a transmission assembly.

[0024] In this embodiment, the heating temperature is regulated by controlling the distance and number between multiple heat replenishment units and the heat storage chamber 1. Specifically, when the end of the rotating arm assembly swings through the arc-shaped channel 19 close to the heat storage chamber 1, the transmission assembly drives the moving assembly to cause the telescopic guide assembly to contract. The end face of the sub-heat storage unit 5 close to the heat storage chamber 1 is in contact with the heat storage chamber 1 for heat exchange or for heating through the fan assembly.

[0025] Preferably, each pair of heat replenishment units is symmetrically arranged on both sides of the heat storage chamber 1, and the two rotating arm assemblies are driven to slide their ends in the arc-shaped channels 19 at two different positions, thereby making the two sub-heat storage units 5 stacked one after the other. This control method effectively increases the width of the heat supply body, which can not only reasonably increase the heating temperature, but also improve the heating endurance by supplementing the volume of the heat storage body.

[0026] In a preferred embodiment, the heat storage chamber 1 has multiple partition plates 2, and heat exchange tubes 3 are mounted on the partition plates 2. Multiple grooves are formed on the end face of the heat storage chamber 1 through the partition plates 2 and the phase change material 4. Each sub-heat storage unit 5 has multiple protrusions on its end face near the heat storage chamber 1 that mate with the grooves. This structure effectively improves the contact heat exchange capacity of the sub-heat storage unit 5 and effectively stores thermal energy within the phase change material of the sub-heat storage unit 5.

[0027] To achieve reasonable control over the sub-thermal storage units 5, including their number and distance, such as... Figure 2As shown in the structural diagram of part A, the rotating arm assembly includes a first motor, a drive gear 14, a driven gear 8, a rotating arm 7, a telescopic assembly, a support plate 17, and an operating shaft 18. The first motor is located on one side of the heat storage chamber 1. The drive gear 14 is fixedly connected to the output shaft of the first motor. The driven gear 8 is rotatably located on one side of the heat storage chamber 1 and meshes with the drive gear 14. One end of the rotating arm 7 is fixedly connected to the center of the end face of the driven gear 8, and the telescopic assembly is located on the rotating arm 7. The support plate 17 is mounted on the end of the telescopic assembly, and the telescopic assembly drives the telescopic movement. The operating shaft 18 is fixedly located on the support plate 17 and rotates with the side wall of the sub-heat storage unit 5. The operating shaft 18 is located on the central axis of the side wall of the sub-heat storage unit 5. The operating shaft 18 is slidably located within the arc-shaped channel 19. The rotation of the rotating arm 7 is driven by the gear transmission structure, thereby lifting the sub-heat storage unit 5. Since the operating shaft 18 is located on the central axis of the side wall of the sub-heat storage unit 5, the sub-heat storage unit 5 always remains vertical.

[0028] Furthermore, to maintain stability, a flexible limiting plate 20 is fixed to the upper sidewall of the arc-shaped channel 19 by a spring 27. When the operating shaft 18 passes through the flexible limiting plate 20, it is limited by the flexible limiting plate 20 to the upper end of the arc-shaped channel 19, which serves to limit and fix it, and relieve the supporting force on the operating shaft 18. The specific structure is as follows: Figure 4 The front view of the heating unit is shown.

[0029] like Figure 2 As shown, the device provides end telescopic functionality. The telescopic assembly includes a second motor 12, a movable plate 15, a lead screw 13, and a support rod 16. The rotating arm 7 has a sliding groove along its length; the second motor 12 is fixedly mounted at one end of the sliding groove. The movable plate 15 is slidably mounted within the sliding groove. One end of the lead screw 13 is rotatably connected to the other end of the sliding groove, and the other end passes through the movable plate 15 and is drively connected to the output shaft of the second motor 12. The lead screw 13 and the movable plate 15 are threaded together. One end of the support rod 16 is fixedly connected to the movable plate 15, and the other end passes through the other end of the rotating arm 7 and is fixedly connected to the support plate 17.

[0030] like Figure 2 As shown, the ends of each arc-shaped channel 19 are connected by a first connecting plate; the moving assembly includes a sliding shaft 21; the end of the arc-shaped channel 19 near the heat storage chamber 1 is fixedly connected to one end of the sliding shaft 21, and the other end of the sliding shaft 21 passes through the heat storage chamber 1 and slides in engagement with the heat storage chamber 1. The transmission assembly includes a limiting plate 11 and a rack 10. The limiting plate 11 is fixedly disposed on one side of the heat storage chamber 1; the bottom of the limiting plate 11 has a groove. The rack 10 is slidably disposed in the groove; the rack 10 meshes with the driven gear 8; the end of the rack 10 is fixedly connected to the end of the arc-shaped channel 19 near the heat storage chamber 1 via a second connecting plate.

[0031] Through the cooperation of the telescopic component and the transmission component, driven by the gear rack, the sub-heat storage unit 5 gradually approaches the heat storage chamber 1 as it rotates, and can further fit into the heat storage chamber 1 for heat exchange and heating.

[0032] A preferred embodiment: such as Figure 3 As shown, there are multiple fans 26 arranged side by side; one fan 26 at one end is driven to move up and down by a lifting assembly. The lifting assembly includes a screw 23, a moving block 24, a third motor 25, and two support plates 22. The two support plates 22 are fixedly mounted on the back of the heat storage chamber 1. Both ends of the screw 23 are rotatably connected to the two support plates 22. The moving block 24 passes through the screw 23 and is threadedly engaged with it; one side of the moving block 24 is fixedly connected to the side of the fan 26. The third motor 25 is fixedly mounted on one of the support plates 22, and its output shaft is driven by the screw 23. The movement of the fans 26 is driven by the screw transmission structure, providing airflow to heat storage media of different thicknesses for heating operations.

[0033] In this embodiment, the device improves the stability and endurance of the heating supply by increasing the number of heat storage units, i.e., the thickness of the phase change material. Increasing the thickness of the heat storage units also increases the length of the heating channel, allowing the heating air to pass through ducts of different lengths, thus maximizing heat exchange or reducing heat exchange time, thereby raising or lowering the heating temperature. Specifically, the length of the heating channel is controlled by controlling the number of overlapping sub-heat storage units 5 (two sets are used in this example, but multiple sets can be configured), and the passage time of the heating air is controlled by controlling the front-to-back distance between the sub-heat storage units 5 and the heat storage chamber 1, thereby achieving the purpose of heating temperature control. Simultaneously, the wind speed and airflow of multiple fans 26, along with their corresponding positions, are coordinated to achieve different heating temperatures.

[0034] Specifically, in this embodiment, multiple arc-shaped channels 19 control the front and rear positions of the sub-heat storage unit 5 and multiple overlapping states. The inner arc-shaped channels 19, in conjunction with the rack and pinion structure and the telescopic structure, achieve the purpose of fitting the sub-heat storage unit 5 with the heat storage chamber 1, so as to better carry out heat exchange and achieve the purpose of heat storage for the sub-heat storage unit 5.

[0035] Another preferred embodiment provides multiple heating units to expand the temperature range and increase temperature adjustability.

[0036] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
