Description

Technical Field

[0001] This invention belongs to the field of refrigeration system technology, and particularly relates to a method and system for synchronous installation of dual refrigerant condenser pipes in a central air conditioning system. Background Technology

[0002] Simultaneous laying of refrigerant and condenser pipes in central air conditioning systems is a standard procedure in electromechanical installation. However, existing construction methods have two inherent flaws. First, the refrigerant and condenser pipes are each equipped with independent rigid supports, and there is no mutual compensation or balancing structure for the load and displacement of the two pipes. The refrigerant's own weight easily presses down on the condenser pipes, resulting in insufficient drainage slope. Adjusting the slope also causes deformation of the refrigerant pipes. At the same time, vibration reduction, heat insulation, and heat preservation require manual wrapping in multiple stages. After hoisting, the pipe inclination angle and pipe wall temperature are measured separately. The process is fragmented, the construction period is long, and it relies solely on manual sampling of slope, lacking multi-dimensional synchronous testing methods. There is no standardized and secure documentation mechanism for the entire construction process, making it impossible to trace the assembly process after quality problems such as leakage or deformation occur.

[0003] Secondly, the industry uniformly adopts fixed values ​​as the isolation distance for hot and cold pipelines, without dynamically adapting to the condenser laying inclination angle and the temperature difference between the refrigerant and the environment. Under conditions of large temperature difference and small slope, cold bridges are easily generated, causing condensation and dampness in the ceiling. Traditional single-point independent adjustment of the hanging brackets can easily cause continuous pipeline wave deformation. The wireless communication conditions in areas such as ceiling mezzanine and equipment well are poor. Existing adjustment tools cannot maintain the assembly form after the signal is disconnected. There is a lack of complete control logic for global collaborative control and offline steady-state maintenance. The cost of rectification for pipeline displacement failure during long-term operation is high. Summary of the Invention

[0004] The purpose of this invention is to provide a method and system for synchronous installation of dual refrigerant condenser pipes in a central air conditioning system, in order to solve the problems mentioned in the background art.

[0005] In view of this, the present invention provides a method for synchronous installation of two refrigerant condenser pipes in a central air conditioning system, specifically including: using a symbiotic tooling with a bidirectional load feedback support structure to synchronously support the two pipes, and constructing a symbiotic assembly base with bidirectional balancing of self-weight and displacement;

[0006] During the synchronous lifting of the tooling, raw data of pipeline tilt angle and temperature difference between hot and cold pipe walls are collected in parallel.

[0007] Based on the tilt angle-temperature difference coupling judgment model, the lateral isolation distance is output synchronously, and the linkage tooling is used to synchronously complete the refrigerant level correction, condensation slope correction, and dynamic adjustment of the cold and hot distance.

[0008] During the tooling clamping and positioning stage, differentiated vibration reduction, heat insulation, and multi-layer insulation integrated molding operations are performed simultaneously.

[0009] All co-existing equipment in the same road section forms a full-domain linkage control matrix, which, together with an offline steady-state maintenance mechanism, enables synchronous fine-tuning of single-point disturbances across the entire domain.

[0010] The automated self-inspection of the points is completed based on a triple parallel judgment standard of load balance, drainage slope, and hot and cold isolation.

[0011] The entire process involves collecting raw data from tooling coupling and control, and then encrypting and generating traceability archives for concealed works.

[0012] Only the self-inspection abnormality points are finely adjusted independently, while the rest of the tooling is kept in a balanced state.

[0013] After all points meet the triple judgment criteria, the entire balancing and adjustment mechanism of the tooling is simultaneously locked to maintain the steady state of the dual-tube symbiotic assembly in the long term.

[0014] In this invention, the symbiotic tooling with a bidirectional load feedback support structure is used to simultaneously support two pipelines and construct a symbiotic assembly base with bidirectional balancing of self-weight and displacement. This includes: independently dividing the symbiotic tooling into a refrigerant-specific bearing cavity and a condenser-specific bearing cavity, and assembling a bidirectional linkage elastic fulcrum between the two cavities.

[0015] The refrigerant pipes and condensate pipes are placed one by one inside their respective bearing cavities to complete the pre-installation and positioning;

[0016] The downward self-weight load of the refrigerant pipeline is converted into a lifting compensation force for the condenser pipeline through the elastic fulcrum, which counteracts the downward deformation of the condenser pipeline.

[0017] The height adjustment action of the condenser pipe generates a horizontal correction force through the fulcrum in the opposite direction, which counteracts the lateral displacement deformation of the refrigerant pipe.

[0018] The mechanical interlocking and balancing of the two pipelines can be achieved with just a single set of tooling, without the need for two independent separate support systems.

[0019] In this invention, furthermore, the lateral isolation distance is synchronously output based on the tilt angle-temperature difference coupling judgment model, and the linkage tooling synchronously completes refrigerant level correction, condensation slope correction, and dynamic adjustment of the hot and cold distance. This includes: retrieving the real-time collected tilt angle θ of the condensation pipe segment and the temperature difference ΔT between the refrigerant and the ceiling environment, and substituting them into the dual-pipe coexistence isolation distance judgment model to complete numerical calculations. The model expression is as follows:

[0020] In the formula: L is the real-time isolation distance between the refrigerant pipeline and the condenser pipeline; ΔT is the real-time temperature difference between the refrigerant pipeline wall and the ceiling environment; θ is the inclination angle of the condenser pipeline segmented laying; K is the pipeline material compatibility coefficient; C is the denominator steady-state correction normal quantity; based on the model output value, the tooling lateral actuator is synchronously driven to adjust the lateral distance between the two pipelines; through the bidirectional linkage elastic fulcrum, the load bidirectional compensation of the two pipelines is continuously completed; the pipeline isolation distance is dynamically changed according to the on-site temperature difference, thus blocking the heat conduction of cold and heat bridges from the structural level.

[0021] In this invention, further, the tooling clamping and positioning stage simultaneously performs differentiated vibration reduction, heat insulation, and multi-layer insulation integrated molding operations, including: laying multi-layer gradient damping pads on the inner side of the refrigerant bearing cavity to complete the refrigerant-side vibration reduction molding;

[0022] A waterproof flexible liner is laid inside the condensation bearing cavity to complete the waterproof and vibration-damping molding of the condensation side.

[0023] A solid thermal insulation interlayer is filled between the two types of load-bearing cavities to complete the thermal insulation molding process.

[0024] An openable, integrated insulation shell is assembled on the outside of the tooling to complete the overall insulation molding of the pipeline's outer perimeter;

[0025] The four types of protective molding operations are completed simultaneously and in one go after the tooling is clamped in place, without any step-by-step wrapping process.

[0026] Furthermore, in this invention, all symbiotic fixtures in the same pipeline section form a global linkage control matrix, which, together with an offline steady-state maintenance mechanism, enables synchronous fine-tuning of single-point disturbances across the entire region. This includes: wirelessly interconnecting all symbiotic support fixtures within the same continuous section of the ceiling to form a global pipeline control matrix.

[0027] After any tooling acquires tilt angle and temperature difference offset signals, the matrix sends synchronous micro-adjustment commands to all tooling in the same section to eliminate pipeline wave deformation caused by single-point adjustment.

[0028] When the tooling loses communication with the wireless network, the current support height and pipe spacing are automatically locked.

[0029] Once network communication is restored, the matrix will synchronously update all control parameters of the entire tooling section.

[0030] In this invention, the automated self-check of the point based on the triple parallel judgment criteria of load balance, drainage slope, and cold and heat isolation includes: verifying the real-time compression compensation stroke of the bidirectional elastic support and performing load balance judgment.

[0031] Retrieve pipeline inclination angle data and compare it with laying standards to determine compliance with drainage slope;

[0032] Compare the actual current pipe spacing with the model output safe spacing, and perform a cold and hot isolation safety determination.

[0033] The corresponding tooling point is deemed qualified only when all three judgment results meet the standards;

[0034] If any of the criteria are not met, the point will be automatically marked as an assembly anomaly point.

[0035] Furthermore, in this invention, the process of collecting raw data of tooling coupling and control throughout the entire process and generating a hidden project traceability file includes: synchronously collecting the unique number of each tooling group, the ceiling installation section, the mechanical compensation stroke of the elastic support, the thermal coupling adjustment output, the dynamic isolation distance, and the raw dataset of the entire tilt angle.

[0036] All collected data are linked to construction time and location coordinates, and irreversible electronic seals are added.

[0037] Integrate all original sensor and adjustment data of tooling within the section to generate a hidden engineering traceability file that can completely reproduce the entire assembly process.

[0038] Furthermore, in this invention, the parallel acquisition of raw data on pipeline tilt angle and hot and cold pipe wall temperature difference during the overall synchronous lifting of the tooling includes: independently configuring a synchronous lifting drive component for each group of symbiotic tooling;

[0039] All lifting drive components in the same section receive unified synchronous start and stop commands to achieve synchronous lifting of the tooling;

[0040] Throughout the entire operation of the tooling lifting machinery, the built-in tilt angle, pipe wall, and ambient temperature sensors continuously collect raw data, with the lifting action and data acquisition carried out in parallel and synchronously.

[0041] In this invention, further, the fine-tuning is only performed independently on the self-inspection abnormal points, while the remaining tooling remains in a balanced state; after all points pass the triple judgment, all the balancing and adjustment mechanisms of the tooling are locked simultaneously to maintain the steady state of the dual-pipe co-assembly in the long term, including: during the calibration phase, only the tooling at the abnormal point is given a fine-tuning command, while the remaining qualified tooling in the section remains in a locked balanced state, without generating disturbance to the entire pipeline.

[0042] The entire locking phase includes synchronous locking of elastic fulcrum limiters, vertical lifting mechanisms, and lateral spacing adjustment mechanisms;

[0043] After locking, the thermal expansion and contraction of the pipeline and the displacement caused by unit vibration are constrained, and the load and displacement of the two pipelines are continuously maintained in a symbiotic balance.

[0044] A central air conditioning refrigerant condenser dual-pipe symbiotic synchronous installation system, which implements a central air conditioning refrigerant condenser dual-pipe symbiotic synchronous installation method, the system including multiple sets of symbiotic support fixtures, a global collaborative networking unit, and a multi-parameter self-testing and evidence storage terminal;

[0045] The symbiotic support fixture includes a fixture base, a refrigerant-specific bearing cavity, a condensation-specific bearing cavity, a bidirectional elastic fulcrum assembly, a synchronous lifting drive component, a thermally coupled electric adjustment assembly, an integrated status sensing assembly, and a differentiated protection assembly.

[0046] The bidirectional elastic support assembly is placed between the two types of bearing cavities to achieve bidirectional mutual feedback and balancing of load and displacement in the two pipelines;

[0047] The synchronous lifting drive receives a unified synchronous command and drives the tooling to lift as a whole.

[0048] The integrated status sensing component synchronously collects raw data on pipeline tilt angle and temperature difference between the pipe wall and the environment.

[0049] The thermally coupled electric regulating component outputs a control signal based on the coupling determination model;

[0050] Differentiated protection components clamp the pipeline and simultaneously complete the integrated molding of vibration reduction, heat insulation, and thermal insulation;

[0051] The global collaborative networking unit is wirelessly interconnected with all symbiotic tooling in the same segment to construct a global control matrix, which has the functions of global synchronous fine-tuning of single-point disturbance and steady-state maintenance of network offline parameters.

[0052] The multi-parameter self-inspection and evidence storage terminal is connected to the global collaborative networking unit. Based on the triple parallel judgment criteria of load balance, slope compliance, and cold and heat isolation, it identifies abnormal assembly points, stores the original encrypted data of the coupling and control of each tooling process, and generates hidden engineering construction archives.

[0053] The beneficial effects of this invention are:

[0054] This invention features a bidirectional load-feedback symbiotic fixture that achieves bidirectional balancing of load displacement in refrigerant and condensate pipes. A single support structure is sufficient for dual-pipe positioning, reducing the amount of auxiliary materials and drilling required. The fixture simultaneously clamps and forms various differentiated protective structures. During hoisting, it collects data on pipe inclination angles and pipe wall temperature differences, eliminating the need for step-by-step wrapping and final testing, thus improving high-altitude construction efficiency. Simultaneously, it performs triple self-checks on load, slope, and thermal isolation, collecting and encrypting original data from the entire process to generate traceability archives. This allows for complete replication of the entire assembly process, early identification of hidden quality defects, and a significant increase in the acceptance rate of concealed works.

[0055] A tilt angle-temperature difference coupling judgment model is adopted to dynamically output the isolation distance between hot and cold pipelines, and adaptively adjusts it according to the on-site working conditions, completely solving the problem of cold bridge condensation caused by fixed spacing laying. All tools in the same section form a global linkage control matrix, and single-point attitude deviation triggers synchronous micro-adjustment of the whole section to eliminate pipeline stress accumulation. At the same time, a network disconnection offline steady state maintenance mechanism is configured to adapt to weak signal construction environments such as ceilings and pipe wells, avoid communication interruption causing pipeline assembly failure, and effectively reduce the workload of later pipeline maintenance and rectification.

For example, the described methods may be performed in a different order than described, and various steps may be added, omitted, or combined. Additionally, features described with reference to certain examples may be combined in other examples.

[0062] This embodiment provides a method for synchronous installation of dual pipes for central air conditioning refrigerant condensation, specifically including: using a symbiotic fixture with a bidirectional load feedback support structure to synchronously support the central air conditioning refrigerant copper pipe and condensation PVC drain pipe. The fixture body integrates a dual-cavity layered load-bearing structure and a bidirectional linkage elastic force transmission fulcrum as the only mechanical coupling medium, eliminating the need to separately purchase and fix two sets of independent pipe hangers. Within the limited space of a single fixture, a symbiotic assembly base is synchronously established where the self-weight pressure, lifting displacement and mutual cancellation of the two pipes are dynamically compensated.

[0063] The entire symbiotic support system forms the underlying mechanical framework. All existing dual-pipe fasteners only achieve static rigid clamping and do not have a force transmission structure for load feedback and displacement reversal compensation. During on-site implementation, only a single expansion bolt is needed to fix the tooling base, eliminating the need for two drilling processes for the refrigerant support and condenser support. At the same time, it avoids a series of chain quality defects caused by traditional split supports, such as long-term downward pressure of the refrigerant pipe due to its own weight, continuous sinking of the condenser pipe drainage slope, manual adjustment of the condenser pipe pulling the refrigerant copper pipe laterally, pipe stress cracking, and water accumulation and leakage in the ceiling.

[0064] During the synchronous lifting of the entire fixture, raw data on pipe inclination angle and temperature difference between hot and cold pipe walls are collected in parallel. Each set of symbiotic fixtures has an integrated embedded sensing module, which integrates a high-precision inclination chip, a pipe wall contact temperature probe, and a ceiling ambient temperature probe. The three types of sensing elements are powered and sampled synchronously, with a sampling period of milliseconds for continuous and uninterrupted acquisition. Throughout the entire process of the fixture's servo lifting mechanism starting the rising and falling motion, the sensing module synchronously outputs the raw sampled data stream. There is no need to wait for the fixture to stop completely or for personnel to climb up and use handheld thermometers and inclination meters to re-measure point by point. The fixture can capture minute deformations of the pipeline in real time during the hoisting process and intervene in correction in advance, greatly reducing the frequency of secondary lifting and rework at high altitudes.

[0065] Based on the tilt angle-temperature difference coupling judgment model, the lateral isolation distance is output synchronously, and the linkage tooling is used to complete the refrigerant level correction, condensation slope correction, and dynamic adjustment of the cold and hot distance. This coupling calculation model is the core control algorithm of this embodiment. It binds the two independent parameters of condensation tilt angle and refrigerant and ambient temperature difference to calculate and output dynamic safety distance. The industry common method is to use only fixed reserved gap for rough construction.

[0066] Specifically, during on-site operation, the tooling's built-in microcontroller retrieves raw sensor data in real time and inputs it into the model for calculation. This synchronously drives the three actuators—the horizontal telescopic actuator, the independent vertical lifting servo motors on both sides—to move in sync. Simultaneously, it corrects the horizontal deviation of the refrigerant pipe, the slope of the condensate drain, and the isolation width of the hot and cold pipes. From a dynamic spatial perspective, it continuously blocks the direct heat exchange between the hot and cold media, completely eliminating the common problems of large-area ceiling condensation and wall mold growth under low-temperature conditions in fixed-gap solutions.

[0067] Secondly, during the tooling clamping and positioning stage, differentiated vibration reduction, heat insulation, and multi-layer insulation are simultaneously performed in an integrated molding process. The tooling's bearing cavity has pre-set partitioned lining slots, an intermediate filling chamber, and an outer hinged insulation shell structure. After the pipeline is fully seated in the bearing cavity's limiting slot, manual operation is only required to fasten the outer insulation clips. The four-layer protective structure—refrigerant-side damping vibration reduction, condensation waterproofing vibration reduction, intermediate solid insulation, and outer composite insulation—is simultaneously and uniformly attached to the pipeline's outer wall in one go. No manual cutting, pasting, or wrapping of various auxiliary materials is needed throughout the process. The four protective processes are combined into a single fastening action, reducing the construction time per meter of pipeline by 60%. All symbiotic tooling within the same pipeline section forms a global linkage control matrix, coupled with an offline steady-state maintenance mechanism to achieve synchronous fine-tuning of single-point disturbances across the entire region. All tooling within a single ceiling-mounted pipeline section forms a closed-loop control matrix through a two-by-two network of LoRa low-latency wireless modules, unlike the existing independent control mode of a single hanging code. If any tooling detects attitude or temperature deviation disturbance signals, the matrix synchronizes at millisecond levels. Micro-adjustment commands are issued to all fixtures in the same section, and the height and spacing of the entire pipeline are simultaneously and slightly corrected, eliminating the wavy pipeline and internal stress accumulation caused by single-point adjustment. For wireless disconnection caused by metal shielding of ceiling layers and equipment wells, the fixture has built-in power-off locking solenoid valves and mechanical limit buckles to form offline steady-state maintenance hardware. All adjustment axes are automatically locked when the network is interrupted, preventing free sliding of pipelines and slope failure. After communication is restored, the matrix batch synchronizes the historical sensing and adjustment parameters of all fixtures in the entire section, eliminating the need for manual reset and calibration of each fixture. The point-based automated self-check is completed based on the triple parallel judgment criteria of load balance, drainage slope, and hot and cold isolation. The fixture has a built-in three-stage parallel self-check subroutine. The three judgment logics are operated synchronously and in parallel rather than sequentially, and the three core indicators of elastic support load compression, condenser tube inclination angle, and model matching isolation spacing are checked simultaneously. Traditional acceptance only relies on manual visual inspection and single-point instrument verification of the single indicator of condenser slope, which cannot detect stress imbalance and cold bridge hazards in advance.

[0068] This solution determines a site's qualification only after all three criteria are met. If any criterion exceeds the limit, the site number, coordinates, and deviation value are immediately locked and uploaded to the terminal, achieving fully automated pre-screening of hidden works hazards, with a near 100% first-time acceptance rate. The entire process involves collecting raw data from the coupled control of the tooling and generating encrypted traceability files for hidden works. From tooling pre-installation, synchronous hoisting, dynamic adjustment, triple self-inspection to final locking, the microcontroller continuously stores the raw sensor data collected every millisecond and the pulse quantity of each motor adjustment. The data not only stores the static results but also preserves the dynamic change curves throughout the entire process. All data is bound to the tooling's unique hardware SN code, the ceiling's three-dimensional coordinates, and the construction timestamp, and encrypted using a national cryptographic irreversible hash algorithm to generate electronic seals. Once generated, these seals cannot be tampered with. In case of ceiling leaks or condensation problems, the entire adjustment process of each tooling point can be completely traced back, accurately locating the root cause of construction deviations and solving the problem of traditional methods that only retain external photos and cannot trace the source. Only self-inspection anomaly points are independently micro-controlled. The system adjusts the remaining tooling to maintain a balanced state. After receiving an abnormal point marker, the system only sends an independent fine-tuning pulse command to the corresponding SN number tooling. The other qualified tooling in the same section keeps the motor locked and the mechanical limit stationary. It will not disturb the balanced mechanical steady state of the entire pipeline to correct local defect disturbances, thus avoiding new deformation and stress accumulation problems caused by synchronous adjustment across the entire area. After all points pass the triple judgment, all the balancing and adjustment mechanisms of the tooling are locked synchronously, maintaining the steady state of the dual-pipe symbiotic assembly in the long term. After all the tooling in the section passes the triple self-inspection, the global networking unit sends a unified global locking pulse. Each set of tooling synchronously triggers the three types of mechanical locking components, namely the elastic fulcrum mechanical limit card, the vertical lifting shaft locking plate, and the lateral spacing locking buckle, to lock synchronously. After locking, the fulcrum compression, lifting displacement, and lateral sliding are completely restricted. It resists the continuous high-frequency vibration of the compressor and the slow displacement caused by the thermal expansion and contraction of the pipeline in winter and summer. It maintains the symbiotic balance structure of the dual pipeline load feedback and displacement compensation all year round, preventing slope failure and pipeline extrusion recurrence after six months of use.

[0069] In this embodiment, the symbiotic tooling with a bidirectional load feedback support structure synchronously supports two pipelines, constructing a symbiotic assembly base with bidirectional self-weight and displacement balancing. This includes: a refrigerant-specific bearing cavity and a condenser-specific bearing cavity, integrally formed by stamping and milling on a metal integrated tooling base, arranged in parallel and layered sections. The refrigerant bearing cavity is located on the upper layer, and the condenser bearing cavity is arranged on the lower layer, with a pre-reserved closed interlayer between the two cavities. A set of bidirectional linkage elastic support components is rigidly fixed inside the interlayer. The support is integrally assembled from a vertical pressure-bearing spring group, a lateral reset spring, and upper and lower force-transmitting top blocks. The upper top block abuts against the bottom plate of the refrigerant bearing cavity, and the lower top block abuts against the support plate of the condenser bearing cavity, forming a mechanical path for bidirectional transmission of vertical load and horizontal displacement. Before the hoisting operation, the construction personnel first... The refrigerant copper pipe of the central air conditioning system is stably embedded into the U-shaped limiting groove of the upper refrigerant-dedicated bearing chamber, and the lateral positioning is completed by the limiting retaining rings on both sides of the groove. Then, the PVC condensate drain pipe is stably placed on the support plate of the lower condenser-dedicated bearing chamber. The front and rear retaining rings of the support plate restrict the back and forth sliding of the condenser pipe. After the two pipes are pre-installed, they naturally maintain the preset parallel distance, without the need for manual alignment and leveling by repeatedly holding a ruler. The refrigerant copper pipe itself and the total weight of the pipe continuously squeeze the bottom plate of the refrigerant bearing chamber downward. The pressure is completely transmitted to the top block of the fulcrum, compressing the vertical bearing spring assembly to move downward. At the same time, the bottom block pushes the condenser bearing support plate upward, automatically generating the overall lifting compensation stroke of the condenser pipe. There is no need to manually add shims to raise the condenser pipe throughout the process, thus offsetting the problem of condenser pipe sinking and insufficient drainage slope caused by the weight of the refrigerant from the source.

[0070] When construction workers need to adjust the height of the condenser pipe to correct the drainage slope, they pry the condenser support plate upwards. The support plate presses against the lower block of the fulcrum, generating a lateral thrust from the spring. This thrust is then reversed through the upper block and acts on the bottom plate of the refrigerant bearing chamber, automatically offsetting the lateral pull and displacement of the refrigerant pipe caused by the condenser lifting. The adjustment actions of the two pipes counterbalance and compensate for each other. The entire load transfer and displacement compensation structure is integrated inside a single set of tooling metal bases. On-site ceiling installation only requires a single drilling and a single set of expansion bolts to fix the tooling. Traditional construction requires drilling holes to fix two separate sets of supports: the refrigerant support and the condenser support. This solution reduces the number of holes drilled for ceiling installation by 50%, and the consumption of auxiliary materials such as vibration damping rubber and fixing clips is also halved. At the same time, it completely eliminates the defects of mutual interference between the two independent supports and long-term compression deformation of the pipes.

[0071] In this embodiment, the lateral isolation distance is synchronously output based on the tilt angle-temperature difference coupling judgment model, and the linkage tooling synchronously completes refrigerant level correction, condensation slope correction, and dynamic adjustment of the hot and cold distance. This includes: the tooling integrated status sensing module continuously and in real time collects the segmented condensation pipe tilt angle θ, refrigerant pipe wall contact temperature, and ceiling ambient air temperature. The microcontroller automatically performs difference calculations to obtain the real-time temperature difference ΔT between the refrigerant and the ceiling environment. All collected raw data are sent in real time to the tooling's built-in 8-bit micro-computing chip, which is pre-programmed with the dual-pipe coexistence isolation distance judgment model. The model expression is as follows:

[0072] In the formula: L is the real-time dynamic safety isolation distance between the refrigerant pipeline and the condenser pipeline; ΔT is the real-time temperature difference between the refrigerant pipe wall and the ceiling environment; θ is the inclination angle of the condenser pipeline segmented laying; K is the pipeline material adaptation coefficient, which is calibrated and written into the chip memory before leaving the factory according to the thermal conductivity and wall thickness of copper pipe and PVC pipe; C is the denominator steady-state correction normal quantity, the value of which is a fixed positive real number. Its function is to avoid the denominator value being too small when the inclination angle θ of the condenser pipeline approaches 0, causing the value of L to suddenly become out of control, thus ensuring the stability of the control. The existing HVAC pipeline control only uses a single parameter of temperature or slope, and there is no design for coupling the two to calculate and output dynamic distance; the chip completes a model iteration calculation every 200ms. After outputting the real-time isolation distance L value, it synchronously sends a drive pulse to the tooling lateral bidirectional electric telescopic actuator to accurately adjust the lateral separation distance between the refrigerant bearing cavity and the condenser bearing cavity, matching the anti-cold bridge safety width calculated by the model. During the synchronous adjustment of the horizontal isolation spacing, the chip synchronously outputs vertical height adjustment pulses to two independent lifting servo motors. This, combined with bidirectional linkage elastic fulcrums, continuously compensates for the load on both pipelines, simultaneously correcting the left-right horizontal deviation of the refrigerant pipeline and the high-low drainage slope deviation of the condensate pipeline. Height correction and spacing adjustment are performed completely synchronously and in parallel, eliminating secondary disturbances caused by sequential adjustments. With the central air conditioning system operating all day and the ambient temperature constantly changing throughout the year, the ΔT value is dynamically updated in real time, and the model continuously iterates and updates the L value. The tooling synchronously and adaptively adjusts the gap between the hot and cold pipelines. In summer, when the temperature difference between the refrigerant and the environment is small, the spacing is automatically narrowed to save ceiling space. In winter, when the temperature is low, the temperature difference is large, and the condensate slope is small, the isolation distance is automatically widened, physically isolating direct heat conduction and completely abandoning the industry's fixed-spacing, crude installation method, eradicating long-term hazards such as large-area condensation on ceilings and dampness and mold on walls.

[0073] Furthermore, during the tooling clamping and positioning stage, differentiated vibration reduction, heat insulation, and multi-layer insulation are simultaneously performed in an integrated molding process. This includes: a multi-layer gradient damping pad is completely pasted onto the inner wall of the U-shaped groove of the refrigerant carrying chamber. The pad is made of a composite pressing of a hard rubber layer and a soft sponge damping layer. The multi-layer gradient structure is specifically adapted to the high-frequency reciprocating vibration during the start-up, shutdown, and operation of the central air conditioning compressor, continuously buffering the frictional impact between the copper pipe and the inner wall of the tooling, and preventing long-term vibration from causing wear and refrigerant leakage on the outer wall of the copper pipe; and a dedicated support plate for the condenser carrying chamber. The fully covered, one-piece molded waterproof, flexible vibration-damping gasket features a co-extruded hydrophobic PE film on the surface and a high-resilience soft rubber inner layer. It is specifically designed to withstand the low-frequency water flow impact vibrations generated by continuous condensate flow within the pipes, while simultaneously preventing condensate droplets from penetrating and corroding the metal base of the tooling, thus preventing tooling rust and failure. The sealed interlayer between the refrigerant carrying chamber and the condensate carrying chamber is filled with a single piece of high-density rigid polyurethane solid insulation. The interlayer has no seams, completely isolating direct heat exchange between the upper low-temperature refrigerant and the lower room-temperature condenser pipes. The core heat transfer path that blocks cold bridge formation is blocked; the tooling base has hinged, openable, integrated insulation shells on both sides, with three layers of pre-fabricated composite insulation cotton inside (inner microporous insulation layer, middle air barrier layer, and outer flame-retardant protective layer). After the pipeline is fully seated in the double-bearing cavity limiting groove, the construction personnel only need to fasten the insulation shell buckles on both sides inward, and the shell automatically and tightly wraps the entire outer circumference of both pipelines; four types of protective molding operation: refrigerant side gradient damping vibration reduction, condenser side waterproof vibration reduction, middle solid heat insulation blocking, and outer three-layer composite insulation. The entire process is completed simultaneously with the tooling clamping the pipeline into place and the insulated shell fastening. Traditional construction procedures involve four steps: separately pasting the refrigerant vibration damping pad, separately laying the condensation waterproofing pad, manually cutting the insulation strip and inserting it into the interlayer, and wrapping multiple layers of insulation cotton on site. These steps are time-consuming. This solution achieves simultaneous fastening and forming in one go, reducing the construction time for a single pipeline protection section by 60%. At the same time, the two types of pipelines are matched with different lining materials for different zones. Compared with universal uniform protective accessories, the comprehensive protection performance of vibration damping, waterproofing, and heat insulation is improved by more than double.

[0074] Furthermore, all symbiotic fixtures within the same pipeline section form a global linkage control matrix, coupled with an offline steady-state maintenance mechanism to achieve global synchronous fine-tuning of single-point disturbances. This includes: embedding LoRa low-latency wireless communication modules into all symbiotic fixtures within the same continuous ceiling pipeline section; setting all fixture modules to the same communication frequency band and the same network ID; automatically pairing and interconnecting in pairs to construct a global closed-loop control matrix covering the entire continuous pipeline section; uniformly allocating timing clocks within the matrix; and ensuring no time difference in data interaction and command issuance among all fixtures.

[0075] Preferably, during matrix operation, if any tooling integrated sensing module detects a pipeline tilt angle deviation or a sudden change in pipe wall temperature, the signal is synchronously uploaded to the global networking unit within milliseconds. The networking unit immediately sends synchronous micro-lifting and lateral fine-tuning pulse commands to all other tools in the same section. All tools in the entire pipeline synchronously and slightly correct their assembly posture, ensuring continuous and uniform stress on the entire pipeline, completely eliminating the problems of wavy bending and long-term internal stress accumulation deformation caused by traditional single-clip independent single-point adjustment. For wireless signal shielding construction scenarios such as ceiling mezzanines and metal pipe wells in computer rooms, each set of symbiotic tools has built-in independent offline steady-state maintenance hardware, including a power-off locking solenoid valve and mechanical limit buckles for each adjustment axis. When the tooling and the global control matrix wirelessly... When the network is disconnected or the signal is lost, the locking solenoid valve is instantly energized to lock the horizontal telescopic mechanism and the output shaft of the vertical lifting motor. At the same time, the mechanical latch automatically locks the displacement stroke of the elastic fulcrum. The tooling is locked at the current support height and the isolation distance between hot and cold pipelines throughout the process, preventing the pipeline from sliding freely or the slope from failing due to signal interruption. After the on-site construction personnel's mobile terminal approaches and the wireless network communication is restored, the global collaborative networking unit reads all the original sensor and adjustment data stored by all tooling during the network outage period in batches, and simultaneously issues the latest set of control benchmark parameters. All tooling in the section is updated in assembly posture simultaneously, eliminating the need for construction personnel to climb up and recalibrate each tool. This adapts to the complex weak current shielded environment of the construction site and greatly reduces the workload of subsequent pipeline maintenance and rectification.

[0076] Furthermore, the automated self-inspection of the point is completed based on the triple parallel judgment criteria of load balance, drainage slope, and cold and heat isolation. This includes: the tooling has a built-in parallel three-channel self-inspection subroutine, and the triple judgment logic is operated synchronously and independently, without the need for sequential testing, which improves the self-inspection efficiency by three times.

[0077] The first channel independently performs load balance determination: it reads the value of the compression stroke sensor inside the bidirectional linkage elastic fulcrum in real time and compares the real-time compression with the factory-preset load balance range to quickly detect two types of stress imbalance risks: refrigerant pipe overload and condenser pipe unloaded floating.

[0078] The second channel independently performs drainage slope compliance determination: it retrieves the original value of the condenser pipe inclination angle collected by the integrated sensor module in real time, compares it with the drainage standard range specified in the HVAC and electromechanical installation specifications, and quickly identifies high-risk points such as condenser pipe back slope, insufficient slope, and local water accumulation.

[0079] The third channel independently performs the cold and heat isolation safety judgment: it reads the current actual isolation distance value of the tooling's lateral telescopic mechanism in real time, and simultaneously retrieves the standard safety distance L output in real time by the coupling model of this invention. The difference between the two sets of values ​​is compared in real time to determine whether the current gap can completely block the heat conduction of the cold and heat bridge. The system only determines that the current tooling point is qualified when all three judgment channels of load balance, drainage slope, and cold and heat isolation output qualified judgment signals. As long as the value of any judgment channel exceeds the preset qualified range, the system immediately binds the tooling's unique SN number, ceiling three-dimensional coordinates, deviation type, and deviation range, and simultaneously pushes it to the on-site handheld terminal to mark it as an assembly abnormality point. Traditional pipeline acceptance relies only on manual handheld inclinometers to randomly check the single indicator of condensation slope, and hidden defects such as stress imbalance and insufficient cold bridge gap cannot be identified in advance. This solution performs triple parallel fully automatic synchronous screening, and 100% of the inherent defects of the hidden works are detected in advance, which greatly reduces after-sales failures such as ceiling leakage and condensation after delivery.

[0080] Furthermore, the entire process of collecting raw data from tooling coupling and control and encrypting it to generate a hidden engineering traceability file includes: throughout the entire lifecycle of the tooling, from pipeline pre-installation, synchronous lifting and hoisting, dynamic coupling adjustment, triple self-inspection to final mechanical locking, the built-in storage chip continuously collects multi-dimensional low-level raw data in real time. The collected content includes the unique hardware SN number of each tooling group, the three-dimensional coordinates of the ceiling section, the full-time mechanical compensation stroke change curve of the bidirectional elastic support, the thermal coupling adjustment L value output by each iteration of the tilt angle-temperature difference coupling model, the real-time dynamic isolation distance of hot and cold pipelines, and the millisecond-level continuous tilt angle raw dataset throughout the hoisting process. The system binds all multi-dimensional low-level raw sensing and adjustment data with the precise timestamps of the start and end of the construction on the day and the identification of the on-site construction team, and calls the built-in national cryptographic encryption module to add a unique and tamper-proof hash algorithm to the entire dataset. Electronic sealing ensures that no personnel or terminal can unilaterally modify or delete any original data collection parameters after encryption, guaranteeing the authenticity and traceability of concealed construction data and preventing subsequent human modification of acceptance records. After all the fixtures in a single-section ceiling undergo triple self-inspection and pass inspection, the global collaborative network unit automatically retrieves the original datasets stored throughout the entire lifecycle of all fixtures within the section and automatically integrates them to generate standardized electronic concealed project traceability archives. The archives fully reproduce the sensor values ​​and motor adjustment pulses corresponding to each step of the operation, from pipeline pre-installation, synchronous hoisting, dynamic spacing adjustment, triple self-inspection to global locking. Traditional construction only retains static photos of the completed appearance and cannot trace the dynamic changes of the entire pipeline assembly process. When ceiling leakage or condensation quality failures occur after delivery, the archives can be directly retrieved to accurately locate the corresponding fixture adjustment deviations throughout the entire time period, quickly distinguishing the responsibilities of construction, materials, and design.

[0081] Furthermore, during the synchronous lifting of the entire tooling, the raw data of pipeline tilt angle and hot and cold pipe wall temperature difference are collected in parallel. This includes: equipping each set of symbiotic tooling bases with an independent servo synchronous lifting drive, with a built-in unified timing signal receiving module that can receive global synchronous start / stop pulse commands issued by the global collaborative networking unit; the synchronous lifting servo drives of all symbiotic tooling within the same ceiling continuous pipeline section synchronously receive the same set of timing start / stop pulse signals, achieving synchronous lifting and lowering of all tooling within the section, with no height difference in the overall pipeline lifting and lowering, and no local pipeline suspension and stretching deformation; throughout the entire process of the tooling servo lifting drive initiating any mechanical action of lifting or lowering, the integrated status sensing module embedded in the side wall of the tooling continuously and synchronously collects three types of raw data. The data collected includes: real-time pipe tilt angle, refrigerant pipe wall contact temperature, and ceiling ambient air temperature. The sensor sampling cycle is completely synchronized with the motor operation cycle. The lifting machinery operation and sensor data acquisition are carried out in parallel and simultaneously, without any separation of time sequence. The traditional construction and fixing process involves first hoisting the entire set of pipelines to the target height and then stopping the machine. Construction workers climb up to erect scaffolding and use independent thermometers and inclinometers to re-measure the posture and temperature of each pipeline section by section. Minor deformations generated during hoisting cannot be captured in real time, requiring multiple hoisting and rework corrections. This solution collects raw sensor data in real time while hoisting, and can simultaneously identify pipeline deviations and make preliminary fine adjustments during the dynamic hoisting stage. This significantly reduces the need for high-altitude scaffolding erection and repeated hoisting operations, improving construction safety and overall installation efficiency.

[0082] Furthermore, the aforementioned independent fine-tuning is only applied to the self-inspection anomaly points, while the remaining tooling maintains a balanced state; after all points pass the triple judgment, all tooling balancing and adjustment mechanisms are simultaneously locked, maintaining a long-term stable state of dual-pipe symbiotic assembly, including: after the entire self-inspection process is completed and the system marks the assembly anomaly points, the entire collaborative networking unit only issues independent attitude fine-tuning pulse commands to the symbiotic tooling with the corresponding SN number of the anomaly point, while all other qualified tooling in the same section maintains a balanced state with the servo motor powered off and locked, and the mechanical limit buckles closed, and will not participate in the entire adjustment simultaneously; only local points are independently corrected, without disturbing the already formed and stress-balanced continuous pipeline, avoiding new wave deformation and internal stress accumulation caused by the synchronous fine-tuning of the entire area; when all tooling in the section has triple parallel self-inspection channels After all outputs of qualified judgment signals, the global collaborative networking unit issues a global synchronous locking pulse command; each set of symbiotic tooling synchronously triggers three types of mechanical locking components to lock synchronously: limit cards at both ends of the bidirectional elastic fulcrum, locking plates of the vertical lifting servo motor, and locking buckles of the horizontal telescopic mechanism; after the global mechanical locking is completed, all adjustment mechanisms are completely de-energized and limited, strictly constraining the compression stroke of the bidirectional linkage elastic fulcrum, the vertical lifting displacement of the tooling, and the lateral sliding offset of the two pipelines; it continuously resists the high-frequency vibration of the central air conditioning unit during daily operation and the slow displacement deformation caused by the thermal expansion and contraction of the pipelines in winter and summer, and maintains a symbiotic mechanical balance structure of mutual load feedback and reverse displacement compensation of the two pipelines year-round, preventing quality problems such as condensation slope sinking, insufficient cold and hot distance, and mutual compression of pipelines after several months of use.

[0083] Another embodiment provides a central air conditioning refrigerant condenser dual-pipe symbiotic synchronous installation system, which performs a central air conditioning refrigerant condenser dual-pipe symbiotic synchronous installation method. The system includes multiple sets of symbiotic support fixtures, a global collaborative networking unit, and a multi-parameter self-testing and evidence storage terminal.

[0084] The symbiotic support fixture is the core physical hardware carrier. Each set of symbiotic support fixtures independently includes an integrated metal fixture base, a layered refrigerant-specific bearing chamber, a layered condenser-specific bearing chamber, a bidirectional elastic fulcrum assembly, a servo synchronous lifting drive, a thermally coupled electric adjustment assembly, an embedded integrated status sensing assembly, and an integrated differentiated protection assembly. The bidirectional elastic fulcrum assembly is the core mechanical component that distinguishes it from all existing fixtures. It is rigidly mounted inside the closed interlayer between the refrigerant-specific bearing chamber and the condenser-specific bearing chamber. The fulcrum is integrally assembled from a vertical pressure-bearing spring group, a lateral reset spring, and upper and lower force-transmitting top blocks. Both ends rigidly abut against the bearing support structure of the two pipelines, fully realizing the bidirectional transmission of the refrigerant and condenser pipeline self-weight load and the mutual compensation and balancing of lifting and lowering displacements. Ordinary dual-pipe clamps on the market only use rigid isolation plates and have no load feedback or displacement reverse force transmission structure, and do not have the same mechanical coupling function. The servo synchronous lifting drive is fixedly installed at the bottom of the fixture base. At the center, the drive unit has a built-in global timing signal receiving module, which can receive unified synchronous lifting commands issued by the global collaborative networking unit, driving the entire tooling base and dual pipelines to rise and fall synchronously, ensuring that the lifting height of pipelines in the same section is completely consistent. The embedded integrated status sensing component is integrated into the side wall of the refrigerant carrying cavity, and simultaneously incorporates an inclination acquisition chip, a pipe wall contact temperature probe, and an ambient temperature sensor. These three types of sensing elements synchronously and continuously collect raw data on the pipeline inclination angle and the temperature difference between the refrigerant pipe wall and the ceiling environment, and transmit it in real time via wired connection to the thermally coupled electric adjustment component and the wireless communication module. The thermally coupled electric adjustment component has a built-in micro computing and storage chip. The tilt angle-temperature difference coupling distance determination mathematical model pre-programmed into the chip can automatically iteratively calculate and output the dynamic safety isolation distance L based on the inclination angle and temperature difference raw data transmitted in real time by the sensing component. It synchronously sends adjustment pulse signals to the horizontal extension actuator and the vertical lifting servo, and synchronously completes the integrated correction of pipeline level, slope, and hot and cold distance.

[0085] The integrated differentiated protection components are hinged to the left and right sides of the tooling base. Internally, they integrate a multi-layer gradient damping gasket on the refrigerant side, a waterproof flexible gasket on the condenser side, a solid insulation interlayer in the middle, and a three-layer composite insulation shell on the outside. After the pipeline is seated in the dual-bearing cavity, the shell is snapped on, simultaneously completing the four types of differentiated protection molding without the need for manual step-by-step operation of various auxiliary materials. The global collaborative networking unit is global control hardware, communicating and interconnecting with all coexisting support tools within the same ceiling installation section via the LoRa low-latency wireless communication protocol to construct a continuous pipeline global closed-loop control matrix. The unit has two built-in control logics: single-point disturbance global synchronous micro-adjustment logic and wireless network disconnection offline mechanical steady-state locking logic, adaptable to ceiling interlayers and metal pipe well wireless screens. To address complex construction environments, the existing pipeline control system maintains a stable, uninterrupted network connection with the complete hardware design. The multi-parameter self-inspection and evidence storage terminal establishes a stable wired data connection with the global collaborative networking unit. The terminal has a built-in parallel three-channel self-inspection operation program and a national cryptographic encryption storage module. The terminal can synchronously retrieve the original data of all tooling's full-cycle bottom-level sensors and motor adjustments within the section. Based on load balance, drainage slope, and cold / heat isolation triple parallel judgment logic, it automatically identifies assembly anomaly points. The terminal's local large-capacity encrypted storage medium stores the original encrypted dataset of the full-process coupling and control of each tooling set for a long time, automatically generating standardized, long-term accessible electronic traceability archives for concealed engineering construction. This supports on-site acceptance and after-sales fault tracing, allowing for complete access to the entire assembly data process.
