Description

Technical Field

[0001] This invention relates to the field of refrigeration units, and more specifically, to a structure for air conditioning water pipes in a refrigeration main unit room and its operation method. Background Technology

[0002] The air conditioning water piping structure for a refrigeration main unit includes a chilled water supply system, cooling tower, cooling water pipes, cooling loads, and auxiliary components. The cooling water circulation system removes heat from the chilled water circulation through the cooling tower or cooling equipment to maintain the chilled water temperature. The cooling water piping network transports cooling water from the cooling tower or cooling equipment to the refrigeration equipment or cooling loads.

[0003] Cooling load refers to the equipment or space in the refrigeration equipment room that requires cooling. The cooling water piping structure needs to deliver cooling water to these cooling loads to absorb heat and lower the room temperature. The circulating water between equipment contains mineral ions such as calcium and magnesium, as well as substances such as carbonates and silicates. When the water temperature rises or becomes concentrated, these substances are prone to precipitate and form scale. At the same time, chloride ions and sulfate ions in the water can also accelerate the corrosion of metal pipes. Summary of the Invention

[0004] This invention provides a structure for air conditioning water pipes in a refrigeration main unit room and its operation method, solving the technical problem in related technologies where circulating water between equipment contains mineral ions such as calcium and magnesium, as well as substances such as carbonates and silicates. When the water temperature rises or becomes concentrated, these substances easily precipitate and form scale. At the same time, chloride ions and sulfate ions in the water also accelerate the corrosion of metal pipes.

[0005] This invention provides an air conditioning water pipe structure for a refrigeration main unit room, including a chiller unit, a chilled water pump unit, a main unit room air conditioning box, a water collection pipe assembly, and a cooling source. The chiller unit is connected to the water-cooled pump unit through pipes, the output end of the main unit room air conditioning box is connected to the water collection pipe assembly through pipes, and the cooling source is connected to the chiller unit through pipes.

[0006] It also includes an external circulation cleaning pipeline, which includes a backup cooling tower. The backup cooling tower is used to supply water to the chiller unit and serves as the cold source for the chiller unit.

[0007] A dosing assembly is installed on the chiller unit. The dosing assembly includes a storage tank, an air inlet pipe, and a feeder. Several sets of feeders are connected to the condenser in the chiller unit.

[0008] The injector includes a connecting flange, a telescopic rod, a sealing spring, and a support spring. The sealing spring and the support spring are both sleeved on the telescopic rod. The support spring is abutted against the bottom outer wall of the sealing spring. A control valve is provided inside the connecting flange. The rod end of the telescopic rod is connected to the control end of the control valve.

[0009] The condenser is connected to temperature-changing pipes at the input and output ends. The temperature-changing pipes are connected to the cold water pump set. The temperature-changing pipes are mainly concentrated in the part where the temperature changes rapidly. An electronic water treatment component is installed on the outer wall of the temperature-changing pipes.

[0010] The electronic water treatment component includes a spiral blade, an electronic generator, and telescopic components. Both ends of the spiral blade are electrically connected to the electronic generator via wires, and two sets of telescopic components are clamped along the length of the spiral blade.

[0011] Furthermore, the telescopic component includes a fixed clamp and a movable clamp. The movable clamp is connected to the fixed clamp via a slide rod. The fixed clamp is abutted against the outer wall of one end of the spiral blade. The outer wall of the movable clamp is provided with a drive source. The drive source drives the slide rod to move along the rod direction, so that the movable clamp compresses the spiral blade along the rod direction to form a cylindrical structure.

[0012] Furthermore, the electronic generator produces an alternating electrical signal with a certain frequency and amplitude, which is induced onto the temperature-sensitive section of the pipe through a spiral blade wrapped around the outside of the pipe. The temperature-sensitive section of the pipe is a corrosion-resistant metal pipe.

[0013] Furthermore, the electron generator is loaded onto the spiral blades of the compressed cylindrical structure to form an alternating electromagnetic field that keeps calcium and magnesium ions in an ionic state in the water, preventing them from crystallizing and forming scale deposits, and gradually dissolving and dispersing existing deposits.

[0014] Furthermore, a chilled water pan or an air-cooled heat exchange chiller is installed in the air conditioning unit of the main computer room, and the chilled water pump unit is connected to the chilled water pan or the air-cooled heat exchange chiller through pipes.

[0015] Furthermore, a condensate drain pipe is also provided on the condenser to remove dirt and wastewater from the condenser.

[0016] Furthermore, a pressure gauge and a volume sensor are installed on the outer wall of the medicine storage tank. The sensing end of the volume sensor extends into the medicine storage tank to monitor the volume of medicine inside the tank.

[0017] Furthermore, the backup cooling tower extends to the circulation pipe through a pipeline. The water collection pipe group includes a water collection pipe, which is connected to the chilled water pan or air-cooled heat exchanger in the main unit's air conditioning unit with an inlet pipe and an outlet pipe. The inlet pipe, outlet pipe, water collection pipe, and circulation pipe form a circulation pipe group.

[0018] Furthermore, a sampling pipe is installed at the top of the standby cooling tower. The sampling pipe is used to sample and check the temperature and concentration ratio of the water source inside the tower. A water source pipe is connected to the bottom of the standby cooling tower. The water source pipe is used to input cooling water.

[0019] This invention also proposes an operation method for an air conditioning water pipe structure for a refrigeration unit room, which operates using the aforementioned air conditioning water pipe structure for a refrigeration unit room, including the following steps:

[0020] S1: Under normal operating conditions, by continuously circulating chilled water and refrigerant in the chiller unit, the chilled water system can continuously absorb heat from the room, transfer the heat to the outside of the condenser, and release the heat through the evaporator, thereby achieving the cooling effect of the main air conditioning unit in the main room.

[0021] S2: When scaling or corrosion occurs, the pipe wall becomes narrow, and pressure increases will occur in the temperature-sensitive pipe. When the internal fluid is pressurized, the sealing spring will be squeezed, and the sealing spring will drive the telescopic rod to rise. After the rod is lifted, the agent is released, squeezing the sealing spring and releasing the agent into the pipe.

[0022] S3: The agent can be a scale inhibitor or corrosion inhibitor. Adding the agent can prevent scale formation and reduce the corrosion rate.

[0023] S4: At the same time, the electronic generator generates an alternating electrical signal with a certain frequency and amplitude, which is induced onto the temperature-changing section pipe through the spiral blades wrapped around the outside of the pipe.

[0024] S5: Next, the spiral blade can be compressed by the telescopic component to form a cylindrical structure. Then, an alternating electromagnetic field is generated by loading the compressed cylindrical spiral blade through an electronic generator to keep calcium and magnesium ions in the water in an ionic state, preventing them from crystallizing and forming scale deposits. At the same time, it can also gradually dissolve and disperse existing deposits.

[0025] S6: Finally, the water collection pump unit circulates all the treated dirt in the cleaning pipeline, and then circulates it out through the pipe end of the water collection pump unit to achieve the management and cleaning of the chiller unit.

[0026] The beneficial effects of this invention are as follows:

[0027] This invention introduces electronic water treatment, which can reduce or prevent scale buildup and deposition on the surfaces of pipes, heat exchangers, and other equipment by altering the physical and chemical properties of water. This reduces pipe resistance and heat exchanger thermal resistance, improving water flow and heat transfer efficiency. Simultaneously, electronic water treatment can change the water's electrical potential and dissolved oxygen content, inhibiting corrosion of metal pipes and equipment. This helps extend the service life of pipes and equipment, reducing the need for maintenance and replacement. By reducing scale and corrosion problems, electronic water treatment can improve the energy efficiency of the main computer room's air conditioning system. Attached Figure Description

Detailed Implementation

[0033] The subject matter described herein will now be discussed with reference to exemplary embodiments. It should be understood that these embodiments are discussed only to enable those skilled in the art to better understand and implement the subject matter described herein, and changes may be made to the function and arrangement of the elements discussed without departing from the scope of this specification. Various processes or components may be omitted, substituted, or added as needed in the examples. Furthermore, features described in some examples may be combined in other examples.

[0034] See Figures 1-4 As shown, an air conditioning water pipe structure and its operation method for a refrigeration main unit include a chiller unit 100, a chilled water pump unit 400, a main unit air conditioning box, a water collection pipe 630 assembly, and a cooling source. The chiller unit 100 is connected to the water-cooled pump unit through pipes. A chilled water pan or an air-cooled heat exchange chiller is provided in the main unit air conditioning box. The chilled water pump unit 400 is connected to the chilled water pan or the air-cooled heat exchange chiller through pipes. The output end of the chilled water pan or the air-cooled heat exchange chiller is connected to the water collection pipe 630 assembly through pipes. The cooling source is connected to the chiller unit 100 through pipes.

[0035] It also includes an external circulation cleaning pipeline, which includes a backup cooling tower 200. The backup cooling tower 200 is used to input to the chiller unit 100 and serves as the cold source for the chiller unit 100.

[0036] The standby cooling tower 200 is equipped with a sampling pipe 210 at the top of the tower. The sampling pipe 210 is used to sample and check the temperature and concentration ratio of the water source inside the tower. A water source pipe 220 is connected to the bottom of the standby cooling tower 200. The water source pipe 220 is used to input cooling water.

[0037] The backup cooling tower 200 extends to the circulation pipe 620 via a pipeline. The water collection pipe 630 group includes the water collection pipe 630, which is connected to the chilled water pan or air-cooled heat exchanger in the main unit air conditioning unit via an inlet pipe 610 and an outlet pipe 640. The inlet pipe 610, outlet pipe 640, water collection pipe 630, and circulation pipe 620 form a circulation pipe group 620. During normal operation, only the inlet pipe 610 and outlet pipe 640 are in operation. When it is necessary to use the cleaning pipeline, the water collection pipe 630 and circulation pipe 620 need to be opened to form a parallel pipe group.

[0038] A dosing assembly 300 is installed on the chiller unit 100. The dosing assembly 300 includes a storage tank 320, an air inlet pipe 310, and a feeder 350. The feeder 350 has several sets, such as... Figure 2 As shown, there are four sets of feeders 350, which are connected to the condensers in the chiller unit 100 respectively.

[0039] The injector 350 includes a connecting flange 353, a telescopic rod 354, a sealing spring 352, and a support spring 351. The sealing spring 352 and the support spring 351 are both sleeved on the telescopic rod 354. The support spring 351 is abutted against the bottom outer wall of the sealing spring 352. A control valve is provided inside the connecting flange 353. The rod end of the telescopic rod 354 is connected to the control end of the control valve.

[0040] It should be noted that a pressure gauge 330 and a volume sensor 340 are provided on the outer wall of the medicine storage tank 320. The sensing end of the volume sensor 340 extends into the medicine storage tank 320 to monitor the volume of medicine in the medicine storage tank 320.

[0041] The pressure gauge 330 is used to monitor the air pressure of the air entering the medicine storage tank 320 through the air inlet pipe 310, so that the medicine powder can be fully injected into the condenser through the injector 350;

[0042] The condenser is also equipped with a condensate drain pipe 110, which is used to remove dirt and wastewater from the condenser.

[0043] The condenser is connected to a temperature-changing section pipe 120 at the input and output ends. The temperature-changing section pipe 120 is connected to the cold water pump unit 400. The temperature-changing section pipe 120 is mainly concentrated in the part where the temperature changes rapidly. An electronic water treatment component 700 is fitted on the outer wall of the temperature-changing section pipe 120.

[0044] The electronic water treatment component 700 includes a spiral blade 710, an electronic generator 730, and a telescopic component. Both ends of the spiral blade 710 are electrically connected to the electronic generator 730 via wires. The telescopic component is provided in at least two sets and is engaged in the length direction of the spiral blade 710.

[0045] The telescopic component includes a fixed clamp 740 and a movable clamp 750. The movable clamp 750 is connected to the fixed clamp 740 via a slide rod. The fixed clamp 740 is abutted against the outer wall of one end of the spiral blade 710. The outer wall of the movable clamp 750 is provided with a drive source. The drive source drives the slide rod to move along the rod direction, so that the movable clamp 750 compresses the spiral blade 710 along the rod direction to form a cylindrical structure.

[0046] A slide bar 720 is provided on the inner wall of the spiral blade 710. The slide bar 720 facilitates the sliding effect when the movable clamp 750 compresses the spiral blade 710 along the rod to form a cylindrical structure.

[0047] The electronic generator 730 generates an alternating electrical signal with a certain frequency and amplitude, which is induced onto the temperature-sensitive section pipe 120 by the spiral blade 710 wound around the outside of the pipe. It is important to note that the temperature-sensitive section pipe 120 is a corrosion-resistant metal pipe.

[0048] An electron generator 730 is loaded onto a spiral blade 710 in a compressed cylindrical structure to form an alternating electromagnetic field that keeps calcium and magnesium ions in the water in an ionic state, preventing them from crystallizing and forming scale deposits. At the same time, it can also gradually dissolve and disperse existing deposits.

[0049] When using chemical agents, scale inhibitors, corrosion inhibitors and other chemicals are added to prevent scale formation and reduce the corrosion rate. An alternating electromagnetic field is used to further create a dissolution and dispersion area, which improves the smooth circulation of the dissolved scale into the cleaning pipeline.

[0050] It should be noted that corrosion-resistant metal pipes should be selected for pipelines, or an anti-corrosion layer should be sprayed onto the inner wall of carbon steel pipes.

[0051] It can also control parameters such as water circulation temperature, flow rate, and concentration factor, reducing the conditions for scale and corrosion formation.

[0052] In one embodiment of the present invention, based on the above-described pipe structure, the following method for operating an air conditioning water pipe structure for a refrigeration unit room is proposed, comprising the following steps:

[0053] S1: Under normal operating conditions, by continuously circulating chilled water and refrigerant in the chiller unit, the chilled water system can continuously absorb heat from the room, transfer the heat to the outside of the condenser, and release the heat through the evaporator, thereby achieving the cooling effect of the main air conditioning unit in the main room.

[0054] S2: When scaling or corrosion occurs, the pipe wall is narrowed, and the pressure will increase in the temperature change section pipe 120. When the internal fluid is pressurized, the sealing spring 352 will be squeezed. The sealing spring 352 will drive the telescopic rod 354 to rise. After the rod is lifted, the agent is released, the sealing spring 352 is squeezed, and the agent is released into the pipe.

[0055] S3: The agent can be a scale inhibitor, corrosion inhibitor, or other chemical. Adding the agent can prevent scale formation and reduce the corrosion rate.

[0056] S4: At the same time, the electronic generator 730 generates an alternating electrical signal with a certain frequency and amplitude, which is induced onto the temperature-changing section pipe 120 through the spiral blade 710 wrapped around the outside of the pipe.

[0057] S5: Next, the spiral blade 710 can be compressed by the telescopic component to make the spiral blade 710 into a cylindrical structure. Then, the electronic generator 730 is applied to the compressed cylindrical spiral blade 710 to form an alternating electromagnetic field so that calcium, magnesium and other ions remain in an ionic state in the water, preventing them from crystallizing and forming scale deposits. At the same time, it can also gradually dissolve and disperse existing deposits.

[0058] S6: Finally, the water collection pump set 500 circulates all the treated dirt in the cleaning pipeline, and then circulates it out through the pipe end of the water collection pump set 500, thus realizing the pipeline cleaning of the chiller unit 100.

[0059] It should be added that, according to fluid statics, when the volume of a container decreases, the space occupied by the same mass of fluid becomes smaller, the average distance between fluid molecules decreases, the number of molecular collisions increases, and thus the pressure increases.

[0060] Numerous control valves are installed at the connections of the above pipes and components. At the same time, the pump set contains several pump bodies for the input and output of circulating water, resulting in different flow directions in the pipes and realizing different pipe connections and circulation.

[0061] The embodiments of this example have been described above. However, this example is not limited to the specific implementation methods described above. The specific implementation methods described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms based on the guidance of this example, and all of them are within the protection scope of this example.
