Description

Technical Field

[0001] The embodiments of the present application relate to the technical field of management of circulating water systems, and in particular to a method for managing and controlling energy conservation and carbon reduction of air conditioners. Background Art

[0002] In traditional circulating water system treatment, for example, when treating circulating water used by cooling towers to cool air-conditioning refrigeration hosts, traditional medicine equipment and sand filters are usually used. Chemicals are added to the circulating water through traditional medicine equipment, and a higher sewage discharge is used until the monitored conductivity parameters meet the requirements for reducing scale. The sand filter filters suspended matter in the circulating water, and a higher sewage discharge is used until the monitored pressure difference meets the requirements for reducing suspended matter in the water. The traditional medicine equipment and sand filter treat the circulating water in parallel and independently, resulting in a large amount of sewage discharge, which reduces the utilization rate of water for cooling the air-conditioning refrigeration hosts in the cooling tower and loses a large amount of cold water when discharging sewage. Summary of the invention

[0003] In view of this, the present application provides an air conditioning energy conservation and carbon reduction management method to improve the utilization rate of water in the cooling tower for refrigerating the air conditioning refrigeration host.

[0004] The present application provides an air-conditioning energy-saving and carbon-reduction management and control method, including: liquid introduction: introducing part of the water conducted from the cooling tower to the refrigeration main unit into a shallow sand filter; filtering: filtering the water using the shallow sand filter to obtain a first filtrate and a first pollutant; removing ions: using a composite electric adsorption device to remove set ions in the first filtrate and solidify the set ions, and obtaining a second filtrate and a second pollutant including the set ions; ionization: using an ionization water purification device to sterilize and remove algae from the second filtrate to obtain a third filtrate, and introducing the third filtrate into the water conducted from the cooling tower to the refrigeration main unit; and discharging pollutants: collecting the first pollutant and the second pollutant and discharging them.

[0005] In the above-mentioned air-conditioning energy-saving and carbon-reduction management and control method, water is successively guided, filtered and deionized, and a part of the water is treated before entering the refrigeration main unit, and most of the first pollutants and second pollutants after treatment are solid suspended matter, particulate matter, organic matter, etc. and solidified set ions. Therefore, the amount of water discharged from the sewage channel is small, which increases the amount of water returning to the liquid inlet channel through the second water channel, thereby improving the utilization rate of water used by the cooling tower to act on the refrigeration main unit, thereby improving the cold capacity utilization rate of low-temperature water, so as to increase the heat exchange efficiency between the cooling tower and the refrigeration main unit.

[0006] In a possible implementation, the air conditioning energy conservation and carbon reduction management method also includes: water replenishment: providing a water tank to store water, connecting the water tank and a water source, the water tank is connected to a cooling tower, and supplies water to the cooling tower; or connecting the cooling tower and a water source, and supplying water to the cooling tower.

[0007] In the above embodiment, the first water replenishment channel connects the water tank or cooling tower and the water source, so that the water source can supply water to the cooling tower through the water tank, or directly to the cooling tower to replenish the water evaporated in the cooling tower and the water loss caused by the discharged first pollutants and second pollutants.

[0008] In a possible implementation, the water replenishment step includes: monitoring the water level: monitoring the water level in a water tank or a cooling tower; when the water level is less than a first set value and greater than or equal to a second set value, performing a first water shortage treatment: using a first pump to direct water into the water tank or the cooling tower.

[0009] In the above embodiment, the first water shortage treatment is to replenish water when there is a serious water shortage in the water tank or cooling tower, thereby avoiding or reducing the cooling effect of the water in the cooling tower on the refrigeration host.

[0010] In a possible implementation, in the step of guiding the liquid, a second pump is provided in the first water channel for guiding the water into the shallow sand filter; the air conditioner energy saving and carbon reduction management method further includes:

[0011] When the water level is less than the second set value, the second water shortage treatment is performed: the filtering, removal and ionization steps are suspended; and the second pump and the first pump are connected in parallel between the water source and the water tank or cooling tower, and the second pump and the first pump are used to respectively introduce water into the water tank or cooling tower.

[0012] In the above embodiment, the steps of filtering, removing and ionizing are suspended to reduce the consumption of water flowing out of the cooling tower, and the first pump and the second pump simultaneously replenish water to the water tank or the cooling tower to improve the efficiency of water replenishment to quickly solve the water shortage problem.

[0013] In one possible implementation, when the implementation time of the second water shortage treatment step is greater than or equal to the set time T, the second water shortage treatment step is stopped; and the third water shortage treatment is performed: the filtering, removal and ionization steps are suspended; the second pump and the first pump are connected in parallel between the water source and the water tank or the cooling tower, and the first pump and the second pump are used to introduce the water source into the cooling tower to conduct water to the liquid inlet channel of the refrigeration main unit.

[0014] In the above implementation, if the second water shortage treatment time is greater than or equal to the set time and the water shortage problem has not been solved, it means that the water shortage is very serious, such as introducing water into the water tank and then introducing it into the cooling tower from the water tank, or directly introducing water into the cooling tower and then introducing it into the refrigeration host from the cooling tower, which prolongs the water replenishment path. In the third water shortage treatment, water is directly introduced into the liquid inlet channel, which shortens the path for water to enter the refrigeration host, ensures the amount of liquid used by the refrigeration host, and achieves the effect of emergency water replenishment.

[0015] In a possible embodiment, in the liquid guiding step, a second pump is set in the first water channel for guiding water into the shallow sand filter; the air conditioning energy conservation and carbon reduction management method also includes: when the second pump fails and the water level is greater than or equal to the first set value, a first fault processing is performed: the first pump and the cooling tower are connected to the liquid inlet channel for guiding water to the refrigeration main unit, so that the first pump guides part of the water in the liquid inlet channel into the shallow sand filter.

[0016] In the above implementation, when the second pump fails, the first pump replaces the second pump to introduce water into the shallow sand filter when the water tank or cooling tower is not short of water, thereby maintaining the water treatment of the WUE control system.

[0017] In a possible implementation, the air conditioning energy conservation and carbon reduction management method also includes: when the second pump fails and the water level is less than the first set value, performing a second fault processing: suspending the filtering, removal and ionization steps; and using the first pump to direct water into the water tank or cooling tower.

[0018] In the above embodiment, when the water level is less than the first set value, it means that the water tank or cooling tower is short of water. In order to give priority to dealing with the water shortage problem, when the second pump fails, the steps of filtering, removing ions and ionizing the water are first suspended to reduce water consumption. At the same time, the first pump introduces water into the water tank or cooling tower, which is beneficial to increase the liquid volume in the cooling tower.

[0019] In one possible implementation, the air conditioning energy conservation and carbon reduction management method also includes: detecting the water level of a water tank or a cooling tower; when the first pump fails and the water level is greater than or equal to a first set value, performing a third fault processing: maintaining the steps of filtering, removing ions, ionizing and discharging pollutants.

[0020] In the above implementation, the water level is greater than or equal to the first set value, the water tank or cooling tower is not short of water, and the failure of the first pump will not affect the water tank to replenish the cooling tower, nor will it affect the direct replenishment of water to the cooling tower, and the WUE control system will maintain the water treatment. When the first pump fails, an alarm is triggered and timely processing is performed, which is conducive to reducing the impact of the failure of the first pump on the operation of the WUE control system.

[0021] In a possible embodiment, in the liquid guiding step, a second pump is set in the first water channel through which water is introduced into the shallow sand filter; the air conditioning energy saving and carbon reduction management method also includes: when the first pump fails and the water level is less than the first set value, a fourth fault processing is performed: suspending the filtering, ion removal and ionization steps, and connecting the second pump with the water tank or cooling tower and the water source, and using the second pump to supply water to the water tank or cooling tower.

[0022] In the above embodiment, when the water level is less than the first set value and the water tank or cooling tower is short of water, the second pump replaces the first pump to introduce water into the water tank or cooling tower, giving priority to solving the problem of water shortage in the water tank or cooling tower; and suspending the steps of filtering, removing ions and ionizing the water, reducing water consumption, which is conducive to increasing the liquid volume in the cooling tower.

[0023] In a possible implementation, the air conditioning energy conservation and carbon reduction management method also includes: monitoring the total amount Q1 of the first pollutant and the second pollutant emitted; monitoring the total amount Q2 of water introduced by the first pump and the second pump, and the total amount Q3 of water introduced in the third water shortage treatment.

[0024] In the above implementation, by monitoring Q1, Q2 and Q3, the utilization rate I of water resources by the WUE management and control system can be calculated to determine the heat exchange efficiency of the cooling tower.

[0025] In a possible implementation, before the step of conducting the liquid, purification is also included: using an ionized water purification device to destroy set ion clusters of the water conducted from the cooling tower to the refrigeration host through a pulsed magnetic field.

[0026] In the above implementation, it is avoided that the water after the set ions are clustered enters the shallow sand filter, the composite electric adsorption device, and the ionization water purification equipment, thereby improving the effect of the water filtration treatment.

[0027] In a possible implementation, the step of removing ions further includes: sterilizing and killing algae using a composite electric adsorption device.

[0028] In the above embodiment, the composite electric adsorption device performs sterilization and algae removal before the ionization water purification device, which increases the number of sterilization and algae removal, reduces the sterilization and algae removal pressure of the ionization water purification device and improves the sterilization and algae removal effect.

[0029] In a possible implementation, the air conditioning energy conservation and carbon reduction management method further includes: monitoring the pH, water quality and / or redox properties of the water in the liquid guiding step.

[0030] In the above embodiment, the pH value, water quality and redox property of the water before entering the shallow sand filter are monitored, which is conducive to alarming when the pH value, water quality and redox property do not meet the requirements. BRIEF DESCRIPTION OF THE DRAWINGS

[0098] In order to further illustrate the technical means and effects adopted by the present application to achieve the intended application purpose, the following is combined with the drawings and implementation methods. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments.

[0099] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used herein in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application.

[0100] In conjunction with the accompanying drawings, some embodiments of the present application are described in detail below. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0101] Please also see Figure 1 and Figure 2 One embodiment of the present application proposes a method for controlling energy conservation and carbon reduction of air conditioners, and implements it through a WUE (Water Use Efficiency) control system 100, which is used for filtering and processing of circulating water systems, such as sterilization and algae removal, slow-release descaling, and solid-liquid separation. The circulating water system is a circulating system for cooling water and chilled water of central air conditioners: the water in the cooling tower 300 flows through the liquid inlet channel D1 after being cooled, and the refrigeration host 400 uses the cooling capacity of the cooled water to obtain water with a higher temperature, which then flows back to the cooling tower 300 through the liquid outlet channel D2, thereby forming a water circulation system between the cooling tower 300 and the refrigeration host 400. The cooling tower 300 uses open heat dissipation to reduce the water temperature, which causes external debris to enter the cooling tower 300 or be polluted by, for example, acid rain, etc. For example, the debris may be dust, leaves, mud, etc. The water flowing into the liquid inlet channel D1 is a mixture including impurities. In order to ensure the quality of water entering the refrigeration host 400, the WUE control system 100 is connected to the liquid inlet channel D1, and part of the introduced water is filtered and then returned to the liquid inlet channel D1, thereby realizing the circulation filtration of the water flowing out of the cooling tower 300, improving the quality of water entering the refrigeration host 400, and reducing or avoiding the damage of water to the refrigeration host 400.

[0102] See also Figure 4 , a method for energy saving and carbon reduction control of air conditioners is implemented using the WUE control system 100, wherein the method for treating water in the liquid inlet channel D1 includes the steps of purification S1, liquid conduction S2, filtration S3, ion removal S4, ionization S5 and pollutant discharge S6 performed in sequence.

[0103] See also Figure 2 and Figure 5 , Figure 5 The schematic diagram of the WUE control system 100 treating the water in the liquid inlet channel D1. The WUE control system 100 includes a shallow sand filter 20, a composite electric adsorption device 30, an ionization water purification device 40, a controller 50, a first water channel T1, a second water channel T2 and a sewage channel T3. The shallow sand filter 20, the composite electric adsorption device 30 and the ionization water purification device 40 are respectively configured to be electrically connected to the controller 50, so that the WUE control system 100 is coordinated by a controller 50 to control each filtering device (shallow sand filter 20, composite electric adsorption device 30 and ionization water purification device 40), which is convenient for unified management, saves management processes and operating costs, reduces the number of controllers 50 and saves power consumption.

[0104] It can be understood that in other embodiments, the controller 50 can also be a control structure external to the WUE management and control system 100 .

[0105] The purification step S1 includes: using an ionization water purification device 40 to destroy set ion clusters in the water in the liquid inlet channel D1 through a pulse magnetic field.

[0106] In one embodiment, the WUE control system 100 further includes a pulse inductance water purification device 10. The pulse inductance water purification device 10 is electrically connected to the controller 50. The controller 50 controls the pulse inductance water purification device 10 to destroy set ion clusters through a pulse magnetic field, for example, the set ions are Ca, Mg, etc.

[0107] The step of guiding liquid S2 includes: guiding part of the water conducted from the cooling tower 300 to the refrigeration host 400 to a shallow sand filter 20 .

[0108] The first water channel T1 is connected between the liquid inlet channel D1 and the shallow sand filter 20 , and then the water in the liquid inlet channel D1 is introduced into the shallow sand filter 20 .

[0109] The filtering step S3 includes filtering water using a shallow sand filter 20 to obtain a first filtrate and a first pollutant.

[0110] The controller 50 controls the shallow sand filter 20 to mainly filter suspended matter in the water, such as the above-mentioned silt, fallen leaves, etc. After the water is filtered by the shallow sand filter 20, a first filtrate and first pollutants including suspended matter and other debris are obtained.

[0111] The step of removing ions S4 includes: using a composite electric adsorption device 30 to remove the set ions in the first filtrate and solidify the set ions, and obtain a second filtrate and a second pollutant including the set ions.

[0112] The WUE management and control system 100 also includes a sewage channel T3. The shallow sand filter 20 and the composite electric adsorption device 30 are respectively connected to the sewage channel T3, so that the first filtrate enters the composite electric adsorption device 30 and the first pollutant enters the sewage channel T3. The controller 50 controls the composite electric adsorption device 30 to remove the set ions in the first filtrate. The controller 50 also controls the composite electric adsorption device 30 to solidify the set ions and obtain the second pollutant and the second filtrate. The second pollutant includes the solidified set ions. The second filtrate is water after the set ions are removed.

[0113] The step of ionization S5 includes: using an ionization water purification device 40 to sterilize and remove algae from the second filtrate to obtain a third filtrate, and introducing the third filtrate into the water conducted from the cooling tower 300 to the refrigeration host 400.

[0114] The composite electric adsorption device 30 is connected to the ionization water purification device 40 and the drainage channel T3, so that the second filtrate enters the ionization water purification device 40 and the second pollutants enter the drainage channel T3. The controller 50 controls the ionization water purification device 40 to sterilize and remove algae from the second filtrate to obtain a third filtrate.

[0115] In one embodiment, the position where the liquid inlet channel D1 is connected to the pulse inductance water purification device 10 is located upstream of the position where the liquid inlet channel D1 is connected to the shallow sand filter 20, so that the set ions maintain an ionic state and enter the first water channel T1, thereby preventing the set ions from being adsorbed on the channel surface after agglomeration, and preventing the water after the set ions are agglomerated from entering the shallow sand filter 20, the composite electric adsorption device 30, and the ionization water purification equipment 40, thereby providing pretreatment for subsequent water treatment to improve the efficiency of water filtration treatment.

[0116] It can be understood that in other embodiments, the purification step S1 and the pulse inductive water purification device 10 can be omitted.

[0117] The step of discharging pollutants S6 includes: collecting the first pollutants and the second pollutants and discharging them.

[0118] The sewage channel T3 is connected to the shallow sand filter 20 and the composite electric adsorption device 30 respectively, so that the first pollutants and the second pollutants are collected in the sewage channel T3 and then discharged.

[0119] In one embodiment, the sewage channel T3 is provided with a sewage interface T34, and the WUE control system 100 further includes a tenth valve M10. The sewage interface T34 is configured to connect to a sewage recovery structure, for example, the sewage interface T34 connects to a water treatment recovery place in a park, etc. The tenth valve M10 is disposed in the sewage channel T3, and is located between the composite electric adsorption device 30 and the sewage interface T34, and is located between the ionization water purification equipment 40 and the sewage interface T34. When the tenth valve M10 is opened, the first pollutant and the second pollutant are discharged from the sewage interface T34.

[0120] In one embodiment, the controller 50 also controls the composite electric adsorption device 30 to perform preliminary sterilization and algae removal on the first filtrate. The composite electric adsorption device 30 performs sterilization and algae removal before the ionization water purification device 40, which increases the number of sterilization and algae removal, reduces the sterilization and algae removal pressure of the ionization water purification device 40, and improves the sterilization and algae removal effect. It can be understood that in other embodiments, sterilization and algae removal can be independently completed by the ionization water purification device 40.

[0121] The second water channel T2 is provided with a reflux interface T21, and the reflux interface T21 is configured to be connected to the inlet channel D1. The second water channel T2 is connected between the ionization water purification equipment 40 and the inlet channel D1. The WUE management and control system 100 also includes a ninth valve M9. The ninth valve M9 is arranged in the second water channel T2 and is located between the reflux interface T21 and the ionization water purification equipment 40. When the ninth valve M9 is opened, the third filtrate flows back into the inlet channel D1 through the second water channel T2, thereby optimizing the water quality in the inlet channel D1. In one embodiment, the controller 50 is connected to at least one terminal 500 for communication, and the terminal 500 makes it more convenient to manage the WUE management and control system 100. The terminal 500 can be a computer terminal, a mobile WeChat terminal, a network printer, a monitoring center, a mobile APP (application, abbreviation of Application) or a WEB (World Wide Web) terminal, etc.

[0122] In the WUE control system 100, the water of the cooling tower 300 is filtered through the shallow sand filter 20, the composite electric adsorption device 30 and the ionization water purification equipment 40 which are connected in sequence. A part of the water of the cooling tower 300 enters the WUE control system 100 for treatment before entering the refrigeration host 400, and most of the first pollutants and the second pollutants after treatment are solid suspended matter, particulate matter, organic matter, etc. and solidified set ions. Therefore, the discharge water volume of the sewage channel T3 is small, which increases the amount of water refluxed to the liquid inlet channel D1 through the second water channel T2, thereby improving the utilization rate of the water of the cooling tower 300 acting on the refrigeration host 400, thereby improving the cold capacity utilization rate of low-temperature water, so as to increase the heat exchange efficiency between the cooling tower 300 and the refrigeration host 400.

[0123] Furthermore, the shallow sand filter 20, the composite electric adsorption device 30 and the ionization water purification equipment 40 all adopt physical treatment methods rather than the method of adding chemicals, thereby reducing or avoiding pollution to the environment and reducing health damage to operators.

[0124] The air conditioning energy saving and carbon reduction management method also includes the following steps: monitoring the pH value, water quality and redox property of the water in the liquid guiding step S2.

[0125] In one embodiment, the WUE management and control system 100 further includes a first sensor 81. The first sensor 81 is installed in the first water channel T1 and is electrically connected to the controller 50. The controller 50 controls the first sensor 81 to measure the pH value of the water in the first water channel T1.

[0126] In one embodiment, the first sensor 81 is a PH (Potential of hydrogen) sensor.

[0127] In one embodiment, the WUE management and control system 100 further includes a second sensor 82. The second sensor 82 is installed in the first water channel T1 and is electrically connected to the controller 50. The controller 50 controls the second sensor 82 to measure the water quality of the water in the first water channel T1.

[0128] In one embodiment, the second sensor 82 is a TDS (Total Dissolved Solids) water quality sensor. For example, the second sensor 82 measures the total amount of solid matter dissolved in water.

[0129] In one embodiment, the WUE management and control system 100 further includes a third sensor 83. The third sensor 83 is installed in the first water channel T1 and measures the redox property of water in the first water channel T1.

[0130] In one embodiment, the third sensor 83 is an ORP (oxidation-reduction potential) sensor.

[0131] It can be understood that in other embodiments, when the WUE management and control system 100 does not need to monitor pH, water quality and redox properties, at least one of the first sensor 81, the second sensor 82 and the third sensor 83 can be omitted.

[0132] Monitoring the pH, water quality and redox property of the water before entering the shallow sand filter 20 is conducive to alarming when the pH, water quality and redox property do not meet the requirements.

[0133] Please continue reading Figure 2 , Figure 4 and Figure 6 The air conditioning energy saving and carbon reduction control method further includes a water replenishment step S7. The water replenishment step S7 includes: supplying water to the cooling tower 300.

[0134] The step of replenishing water S7, the step of purifying S1, and the steps of guiding liquid S2, filtering S3 and removing ions S4 performed in sequence can be performed independently.

[0135] The cooling tower 300 is in an open state. The evaporation of water in the cooling tower 300, the first pollutants and the second pollutants discharged by the shallow sand filter 20 and the composite electric adsorption device 30, and the water consumption of the refrigeration host 400 for energy exchange will cause the loss of water in the cooling tower 300. In order to avoid reducing the amount of water used by the refrigeration host 400, the water tank 200 replenishes water into the cooling tower 300 to make up for the loss.

[0136] In one embodiment, the WUE management and control system 100 also includes a first water replenishment channel T4. The first water replenishment channel T4 is configured to be connected to a water tank 200. The first water replenishment channel T4 is provided with a water replenishment interface T41 and a water outlet interface T42. The water replenishment interface T41 is configured to be connected to a water source (not shown). The water outlet interface T42 is configured to be connected to the water tank 200. Water enters the first water replenishment channel T4 from the water replenishment interface T41, and flows out from the water outlet interface T42 through the first water replenishment channel T4 and enters the water tank 200. The water tank 200 replenishes water to the cooling tower 300 at a constant pressure.

[0137] When the water tank 200 is short of water, it may cause the problem of untimely replenishment of liquid to the cooling tower 300, or insufficient liquid in the cooling tower 300, which will further affect the cooling effect of the water in the cooling tower 300 on the refrigeration host 400. The air conditioning energy saving and carbon reduction management method also includes a processing method when the water tank 200 is short of water.

[0138] See also Figure 7 The step of replenishing water S7 includes the steps of monitoring water level S8 and first water shortage processing S9. The step of monitoring water level S8 includes: monitoring the water level of the water tank 200.

[0139] In one embodiment, the WUE management and control system 100 further includes a water level meter 71. The water level meter 71 is configured to be placed in the water tank 200 and measure the water level in the water tank 200.

[0140] It is understood that the water tank 200 may also be omitted. Figure 3 As shown, the water outlet interface T42 of the first water replenishment channel T4 is configured to communicate with the cooling tower 300, and the water level meter 71 is installed in the cooling tower 300. The first water replenishment channel T4 directly guides water into the cooling tower 300.

[0141] It is determined whether the water level measured by the water level meter 71 is less than the first set value. If the result of the determination is no, there is no need to add water to the water tank 200. If the result of the determination is yes, it is further determined whether the water level of the water tank 200 is less than the second set value. If the result of the further determination is no, the first water shortage process S9 is performed. If the result of the further determination is yes, the second water shortage process S10 is performed. The water shortage degree of the second water shortage process S10 is higher than the water shortage degree of the first water shortage process S9.

[0142] That is, when the water level is less than the first set value and greater than or equal to the second set value, the first water shortage process S9 is performed. The first water shortage process S9 includes: using the first pump 61 to introduce water into the water tank 200, such as Figure 6 .

[0143] The first water shortage process S9 replenishes water when the water tank 200 is seriously short of water, thereby avoiding or reducing the cooling effect of the water in the cooling tower 300 on the refrigeration host 400.

[0144] See also Figure 2 In one embodiment, the WUE management and control system 100 further includes a second pump 62 electrically connected to the electric controller. The second pump 62 is disposed in the first water channel T1. The second pump 62 can accelerate the flow rate of water in the first water channel T1.

[0145] The second water shortage treatment step S10 includes: pausing filtration S3, removing ions S4, and ionizing S5, and connecting the second pump 62 and the first pump 61 in parallel between the water source and the water tank 200, and using the second pump 62 and the first pump 61 to introduce water into the water tank 200 respectively.

[0146] In one embodiment, the WUE control system 100 further includes a second water replenishment channel T5, and a first valve M1 and a second valve M2 electrically connected to the controller 50. The first pump 61 and the first valve M1 are respectively installed in the first water replenishment channel T4, and the first pump 61 is located between the first valve M1 and the water tank 200.

[0147] The second water replenishment channel T5 is provided with a first interface T51 and a second interface T52. The first interface T51 is connected to the first water replenishment channel T4. The second interface T52 is connected to the first water channel T1. The first interface T51 is located between the first pump 61 and the first valve M1. The second valve M2 is installed in the second water replenishment channel T5 and is located between the first interface T51 and the second interface T52.

[0148] The water entering the water replenishment interface T41 is conducted to the first water replenishment channel T4 and the second water replenishment channel T5 connected in parallel through the first pump 61. The first valve M1 controls the on-off of the first water replenishment channel T4. When the first valve M1 is opened, water enters the water tank 200 through the first water replenishment channel T4. When the second valve M2 is opened, water enters the first water channel T1 through the second water replenishment channel T5.

[0149] In one embodiment, the WUE management and control system 100 further includes a third water replenishment channel T6 and a third valve M3, a fourth valve M4 and a fifth valve M5 configured to be electrically connected to the controller 50. The third water replenishment channel T6 is provided with a third interface T61 and a fourth interface T62. The third interface T61 is connected to the first water replenishment channel T4 and is located between the first pump 61 and the water replenishment interface T41. The fourth interface T62 is connected to the first water channel T1. The third valve M3 is installed in the third water replenishment channel T6. The first water channel T1 is provided with a liquid inlet interface T11 and is connected to the liquid inlet channel D1 through the liquid inlet interface T11. The fourth valve M4 and the fourth valve M5 are respectively installed in the first water channel T1, the fourth valve M4 is located between the liquid inlet interface T11 and the fourth interface T62, and the fifth valve M5 is located between the second interface T52 and the shallow sand filter 20. The second pump 62 is located between the second interface T52 and the fourth interface T62.

[0150] See also Figure 2 and Figure 8 , close the fourth valve M4, and open the first valve M1, the second valve M2 and the third valve M3, so that the third water replenishment channel T6, the first water channel T1 and the second water replenishment channel T5 between the second interface T52 and the fourth interface T62 form a water replenishment branch, and the second pump 62 can accelerate the flow rate of water in the water replenishment branch; the first water replenishment channel T4 between the first interface T51 and the third interface T61 forms another water replenishment branch, and the first pump 61 can accelerate the flow of water in the other water replenishment branch, thereby realizing that the first pump 61 and the second pump 62 replenish water to the water tank 200 at the same time.

[0151] The steps of filtering S3, removing and ionizing S5 are suspended to reduce the consumption of water flowing out of the cooling tower 300, and the first pump 61 and the second pump 62 replenish water to the water tank 200 at the same time to improve the efficiency of water replenishment to quickly solve the water shortage problem.

[0152] See also Figure 7 , while performing the second water shortage process S10 , determining whether the water level of the water tank 200 is less than the first set value, if the determination result is yes, the second water shortage process S10 is stopped to stop replenishing water to the water tank 200 .

[0153] The step of replenishing water S7 also includes: judging whether the time of the second water shortage treatment S10 is greater than or equal to the set time, and if the judgment result is yes, stopping the second water shortage treatment S10 and performing the third water shortage treatment S11; if the judgment result is no, continuing the second water shortage treatment S10 until the water level of the water tank 200 is greater than or equal to the first set value.

[0154] The third water shortage treatment S11 includes the steps of suspending filtration S3, removing ions S4 and ionizing S5. The second pump 62 and the first pump 61 are connected in parallel between the water source and the water tank 200, and the first pump 61 and the second pump 62 are used to introduce water into the liquid inlet channel D1.

[0155] If the time of the second water shortage processing S10 is greater than or equal to the set time and the water shortage problem has not been solved, it means that the water shortage is very serious. For example, water is introduced into the water tank 200 and then introduced into the cooling tower 300 from the water tank 200, and then introduced into the refrigeration main unit 400 from the cooling tower 300, which prolongs the water replenishment path. In the third water shortage processing S11, water is directly introduced into the liquid inlet channel D1 through two parallel paths, which shortens the path for water to enter the refrigeration main unit 400 and ensures the amount of liquid used by the refrigeration main unit 400.

[0156] See also Figure 2 and Fig. 9, the WUE control system 100 also includes a fourth water replenishment channel T7, and a sixth valve M6 and a seventh valve M7 electrically connected to the controller 50. The fourth water replenishment channel T7 is provided with a fifth interface T71 and a sixth interface T72. The fifth interface T71 is connected to the second water replenishment channel T5, and the sixth interface T72 is configured to be connected to the liquid inlet channel D1. The seventh valve M7 is installed in the second water replenishment channel T5 and is located between the second interface T52 and the second valve M2. The sixth valve M6 is installed in the fourth water replenishment channel T7 and is located between the fifth interface T71 and the sixth interface T72.

[0157] When the first valve M1 is closed, water is blocked from entering the water tank 200 from the first water replenishment channel T4 during water replenishment. When the fifth valve M5 is closed, water is blocked from entering the shallow sand filter 20 through the first water channel T1 during water replenishment.

[0158] The second valve M2, the third valve M3, the seventh valve M7 and the sixth valve M6 are opened, and water enters the first water replenishment channel T4 through the water replenishment interface T41, and passes through the third interface T61, the first pump 61, the first interface T51, the second valve M2, the fifth interface T71, the fourth water replenishment channel T7 and the sixth valve M6 in sequence, and then enters the liquid inlet channel D1 through the sixth interface T72; and water enters the first water replenishment channel T4 through the water replenishment interface T41, and passes through the third interface T61, the third water replenishment channel T6, the third valve M3, the fourth interface T62, the first water channel T1, the second pump 62, the second interface T52, the second water replenishment channel T5, the seventh valve M7, the fifth interface T71, the fourth water replenishment channel T7 and the sixth valve M6 in sequence, and then enters the liquid inlet channel D1 through the sixth interface T72.

[0159] The first water replenishment channel T4 between the water replenishment interface T41 and the third interface T61 flows backward through two paths and then converges to the fourth water replenishment channel T7, and then enters the liquid inlet channel D1 through the sixth interface T72: Path one: the first water replenishment channel T4 between the third interface T61 and the first interface T51, and the second water replenishment channel T5 between the first interface T51 and the fifth interface T71; Path two: the third water replenishment channel T6 between the third interface T61 and the fourth interface T62, the first water replenishment channel T4 between the fourth interface T62 and the second interface T52, and the second water replenishment channel T5 between the second interface T52 and the fifth interface T71.

[0160] In path one, the first pump 61 accelerates the flow of water; in path two, the second pump 62 accelerates the flow of water, thereby improving the water replenishment efficiency to speed up the solution to the very serious water shortage problem.

[0161] It can be understood that in other embodiments, the seventh valve M7 can also be omitted. When the seventh valve M7 is not provided in the water replenishment channel, the flow path of water in the third water shortage treatment S11 will not be changed.

[0162] See also Figure 7 During the third water shortage process S11, it is determined whether the water level of the water tank 200 is less than the first set value. If the determination result is yes, the third water shortage process S11 is stopped to stop replenishing water to the water tank 200 S7.

[0163] In one embodiment, the second water shortage treatment step S10 and the third water shortage treatment step S11 further include a step of maintaining clean water, which is beneficial to protecting the pipeline, but is not limited thereto. It can be understood that in other embodiments, the water intake step can also be suspended in the second water shortage treatment step S10 and the third water shortage treatment step S11.

[0164] See also Fig.10 In one embodiment, the air conditioning energy saving and carbon reduction management method also includes a processing method when the second pump 62 fails.

[0165] When the second pump 62 fails, the controller 50 receives a signal and determines whether the water level of the water tank 200 measured by the water level meter 71 is less than the first set value. When the judgment result is no, the first fault processing S12 is performed, and when the judgment result is yes, the second fault processing S13 is performed.

[0166] The step of the first fault processing S12 includes: connecting the first pump 61 and the liquid inlet channel D1, so that the first pump 61 introduces part of the water in the liquid inlet channel D1 into the circulation processing system.

[0167] See also Figure 2 and Fig.11 In one embodiment, the WUE management and control system 100 further includes an eighth valve M8 electrically connected to the controller 50. The eighth valve M8 is disposed in the first water replenishment channel T4. The third interface T61 is located between the first pump 61 and the eighth valve M8.

[0168] The eighth valve M8 is closed to prevent water from entering the first water replenishment channel T4 between the eighth valve M8 and the first pump 61, thereby implementing the step of stopping water replenishment S7.

[0169] Close the first valve M1, the sixth valve M6 and the eighth valve M8, and open the fourth valve M4, the third valve M3, the second valve M2, the seventh valve M7 and the fifth valve M5, so that the water in the liquid inlet channel D1 enters the first water channel T1 between the liquid inlet interface T11 and the fourth interface T62, the fourth water replenishment channel T7 between the fourth interface T62 and the third interface T61, the first water replenishment channel T4 between the third interface T61 and the first interface T51, the second water replenishment channel T5 between the first interface T51 and the second interface T52, and the first water channel T1 between the second interface T52 and the shallow sand filter 20 in sequence, so that part of the water in the liquid inlet channel D1 flows into the shallow sand filter 20. When the second pump 62 fails, the first pump 61 replaces the second pump 62 to introduce water into the shallow sand filter 20 when the water tank 200 is not short of water, so as to maintain the water treatment of the WUE control system 100.

[0170] See also Fig.12 The second fault processing step S13 includes: pausing filtering S3, removing and ionizing S5; and using the first pump 61 to introduce the water source into the water tank 200.

[0171] During the second fault processing S13, the ionization water purification device 40 operates normally.

[0172] When the water level is less than the first set value, it indicates that the water tank 200 is short of water. To give priority to the water shortage problem, when the second pump 62 fails, the steps of filtering the water S3, removing ions S4 and ionizing S5 are suspended to reduce water consumption. At the same time, the first pump 61 introduces water into the water tank 200, which is beneficial to increase the liquid volume in the cooling tower 300.

[0173] See also Fig.13 In one embodiment, the air conditioning energy saving and carbon reduction management method also includes a processing method when the first pump 61 fails.

[0174] When the first pump 61 fails, the controller 50 receives a signal and determines whether the water level of the water tank 200 measured by the water level meter 71 is less than the first set value. When the judgment result is no, the third fault processing S14 is performed, and when the judgment result is yes, the fourth fault processing S15 is performed.

[0175] See also Figure 5 The steps of the third fault processing S14 include: maintaining filtration S3, removing ions S4, ionizing S5 and discharging pollutants S6.

[0176] The water level is greater than or equal to the first set value, the water tank 200 is not short of water, and the failure of the first pump 61 will not affect the water supply from the water tank 200 to the cooling tower 300, and the water treatment by the WUE control system 100 is maintained. When the first pump 61 fails, an alarm is triggered and timely processing is performed, which is conducive to reducing the impact of the failure of the first pump 61 on the operation of the WUE control system 100.

[0177] See also Figure 2 and Fig.14 The fourth fault processing step S15 includes: pausing the steps of filtering S3, removing ions S4 and ionizing S5, and connecting the second pump 62 with the water tank 200 and the water source, and using the second pump 62 to supply water to the water tank 200.

[0178] When the water level is less than the first set value, the water tank 200 is short of water, and the problem of the water tank 200 being short of water is preferentially addressed.

[0179] The fifth valve M5 is closed to implement the steps of pausing the filtration S3, the ion removal S4 and the ionization S5.

[0180] The fifth valve M5 and the third valve M3 are closed, and the fourth valve M4, the seventh valve M7, the second valve M2 and the first valve M1 are opened, so that after water enters from the water replenishment interface T41, it passes through the first water replenishment channel T4 between the water replenishment interface T41 and the third interface T61, the third water replenishment channel T6 between the third interface T61 and the fourth interface T62, the first water channel T1 between the fourth interface T62 and the second interface T52, the second water replenishment channel T5 between the second interface T52 and the first interface T51, and the first water replenishment channel T4 between the first interface T51 and the water tank 200, so that the second pump 62 replaces the first pump 61 to introduce water into the water tank 200; and the steps of filtering S3, removing ions S4 and ionizing S5 of water are suspended to reduce water consumption, which is conducive to increasing the liquid amount in the cooling tower 300.

[0181] In the steps of the first water shortage process S9, the second water shortage process S10, the third water shortage process S11, the second fault process S13 and the fourth fault process S15, the first pump 61 and / or the second pump 62 directly introduces water into the cooling tower 300 through the first water replenishment channel T4.

[0182] The first pump 61 and the second pump 62 can work independently when operating normally, can jointly replenish water when the water tank 200 or the cooling tower 300 is short of water, and can replace the other when one of them fails, thereby improving the intelligence of the WUE management and control system 100.

[0183] In one embodiment, the air conditioner energy conservation and carbon reduction control method further includes calculating the utilization rate I of water resources by the WUE control system 100: monitoring the total amount Q1 of the first pollutant and the second pollutant emitted.

[0184] The total amount Q2 of water introduced by the first pump 61 and the second pump 62 and the total amount Q3 of water introduced in the third water shortage process S11 are monitored.

[0185] I = (Q2-Q3-Q1) / (Q2-Q3).

[0186] In one embodiment, please refer to Figure 2 , the WUE control system 100 also includes an inlet flow meter 72. The inlet flow meter 72 is installed in the first water replenishment channel T4 and is located between the third interface T61 and the water replenishment interface T41, so that the total amount of water Q2 introduced by the first pump 61 and the second pump 62 can be obtained. The third water shortage process S11 is an emergency process for water shortage in the water tank 200, which belongs to the non-routine working state of the WUE control system 100, and therefore should be excluded when calculating I.

[0187] When the third water shortage treatment S11 is performed, the inlet flow meter 72 is closed, so that the total amount Q3 of water introduced during the third water shortage treatment S11 is equal to zero.

[0188] The sewage discharge channel T3 includes a first channel T31, a second channel T32 and a third channel T33. The first channel T31 is connected between the second channel T32 and the shallow sand filter 20. The third channel T33 is connected between the second channel T32 and the composite electric adsorption device 30. The WUE control system 100 also includes a discharge flow meter 73, which is used to measure the total amount Q1 of the first pollution and the second pollutant in the third channel T33.

[0189] Therefore, the utilization rate of water resources by the WUE management and control system 100 is I=(Q2-Q3-Q1) / (Q2-Q3)=(Q2-Q1) / Q2.

[0190] By measuring the inlet flow meter 72 and the discharge flow meter 73, the utilization rate I of water resources by the WUE management and control system 100 can be calculated to determine the heat exchange efficiency of the cooling tower 300.

[0191] The shallow sand filter 20, the composite electrosorption device 30 and the ionization water purification equipment 40 are connected in series, and only a second pump 62 is needed to introduce the water into the liquid inlet channel D1. There is no need for the shallow sand filter 20, the composite electrosorption device 30 and the ionization water purification equipment 40 to each set up a pump to guide the liquid. The volume of the pump is relatively large. The WUE control system 100 reduces the number of pumps, thereby effectively reducing the occupied space.

[0192] In the above-mentioned air-conditioning energy-saving and carbon-reduction management and control method, water is successively conducted through liquid conduction, filtration and deionization, and a part of the water is treated before entering the refrigeration main unit, and most of the first pollutants and second pollutants after treatment are solid suspended matter, particulate matter, organic matter, etc. and solidified set ions. Therefore, the amount of water discharged from the sewage channel is small, which increases the amount of water returning to the liquid inlet channel through the second water channel, thereby improving the water utilization rate of the cooling tower acting on the refrigeration main unit.

[0193] The above embodiments are only used to illustrate the technical solution of the present application rather than to limit it. Although the present application is described with reference to the embodiments, a person skilled in the art should understand that the technical solution of the present application can be modified or replaced by equivalents without departing from the spirit and essence of the technical solution of the present application.
