Description

Technical Field

[0001] The present invention relates to the technical field of building engineering, and in particular to a structural column heat exchange system and method. Background Art

[0002] In recent years, with the rapid development of my country's construction industry, the quality requirements for reinforced concrete buildings have become increasingly stringent. To enhance the integrity and stability of buildings, most architects have incorporated reinforced concrete structural columns into the walls of multi-story brick-concrete structures. These columns are connected to ring beams at each floor level, forming a space frame that is resistant to bending and shear, and have become an effective measure to prevent building collapse. However, traditional reinforced concrete structural columns are ineffective in terms of energy conservation. Reinforced concrete has poor thermal conductivity, which can cause thermal bridges during building heat transfer in extremely cold regions. This leads to large temperature differences between hot and cold zones within different zones, resulting in significant energy losses during energy transfer and poor energy conservation. Furthermore, reinforced concrete structures are complex to construct and require high-quality concrete molding. This necessitates that vibration compaction be a strictly controlled indicator. However, structural columns are typically as high as a standard floor, making vibration difficult and requiring numerous construction steps. This leads to frequent quality problems such as poor molding quality. Therefore, to achieve the goals of convenient construction, high molding quality, high economic performance, and energy conservation and emission reduction, improvements to existing structural columns are necessary.

[0003] 2. Existing multi-story or high-rise public buildings often suffer from large temperature differences between floors, resulting in uneven thermal energy utilization and an inability to coordinate thermal energy regulation between floors, leading to thermal energy waste. Although central air conditioning can regulate the temperature of each floor, it consumes significant electricity. Its mechanism relies on heat exchange between the interior and exterior of the building structure, and it is unable to regulate thermal energy between the various floors within the building structure. Summary of the Invention

Existing structural columns are cumbersome to construct, have high energy consumption, and have poor molding quality; 2.

[0042] Example 4

[0043] like Figure 1-7As shown, the structural column 01 is cast and formed by foam concrete material; it solves the problems of poor thermal conductivity (easy to form broken bridges) of conventional reinforced concrete structural columns, poor energy-saving effects, complicated construction procedures, and inconvenient vibration, which lead to poor quality of structural column molding. The structural column constructed by foam concrete does not require vibration, which can effectively improve the heat transfer performance of the structural column and reduce energy loss.

[0044] Example 5

[0045] like Figure 1-7 As shown, the construction method of the structural column heat exchange system includes the following steps:

[0046] S1: Install the structural column reinforcement, tie the heat transfer components and the rigid insulation pipe, and leave a portion of the rigid insulation pipe that passes through the surface of the structural column (to facilitate connection with the base);

[0047] S2: Masonry construction at reserved structural column locations;

[0048] S3: Pre-embedded masonry tie bars;

[0049] S4: Install the structural column formwork and reserve a diversion port to facilitate the insertion of the foam concrete conduit;

[0050] S5: Foam concrete pouring;

[0051] S6: Foam concrete curing;

[0052] S7: Install control components and heat transfer plates on the formed structural columns, install temperature sensors in the areas of each floor space, and install a control system within the building structure.

[0053] In this embodiment, the construction technology of the relevant structural columns is existing technology and will not be described in detail here.

[0054] Example 6

[0055] Based on the above embodiments, this embodiment discloses a method for using a structural column heat exchange system, such as Figure 1-6 As shown, it should be noted that: this method is applicable to use in public buildings of a single economic entity. If it is a residential building or a building of a non-single economic entity, it is necessary to coordinate whether the various households and different economic units in the building agree to use this system; sign relevant agreements to avoid disagreements; the method of use includes: in the area of each floor space, temperature data is collected by temperature sensors, and the control system obtains the usage status of each area through the input information of the human-computer interaction device, and the unused area is used as the non-heat exchange area, and the used area is used as the heat exchange area. Based on the temperature data in the heat exchange area, the heat energy in the high-temperature area is transferred to the low-temperature area to achieve coordinated utilization of heat energy.

[0056] In this embodiment, it should be noted that due to the different orientations, structures, electrical appliance usage environments, thermal insulation performance and air conditioning or heating usage habits of each area, the temperature differences in each area will be very different. After the control system sets the maximum and minimum temperatures of each area according to seasonal factors, heat can be transferred from areas with excess heat energy to areas with insufficient heat energy, and the use of air conditioning or heating can be reduced. Through the coordinated use of heat energy, heat energy waste can be avoided.

[0057] Example 7

[0058] like Figure 1-7 As shown, when heat energy needs to be input to a certain area, the first electric cylinder 013 in the area is actuated to retract the heat insulation plate 014, and then the second electric cylinder 016 is actuated to dock the heat-conducting metal rod 3 018 in the plug-in rod with the heat-conducting metal rod 2 062, and at the same time, the plug-in block 024 is docked with the plug-in slot 020 (the heat energy channel is conductive); when heat energy needs to be output from a certain area, the same operation is used to dock the plug-in block 024 with the heat transfer plate (plug-in slot) of the area and the heat-conducting metal rod 3 018 with the heat-conducting metal rod 2 062; the control system realizes the coordinated utilization of heat energy by setting the heat output area and the heat receiving area. Its heat conduction efficiency depends on the temperature difference between the two areas, the heat conductivity of the heat-conducting metal rods 1 to 3, and the heat conductivity of the plug-in block and the heat transfer plate. The relevant insulation layer, hard insulation pipe, and insulation shell play a role in preventing heat energy from being lost in transit.

[0059] It should be noted that the heat transfer plate 012 located at the top of the structural column 01 is used to output heat energy (the rising effect of hot air), and the heat transfer plate 012 located at the bottom of the structural column 01 is used to input heat energy (inputting heat energy from the bottom can facilitate the temperature rise from the bottom up in the area, thereby improving human comfort).
