Description

Technical Field

[0001] The present invention relates to the technical field of recycling air-conditioning condensed water, and in particular to a cooling system for recycling air-conditioning condensed water and a control method thereof. Background Art

[0002] In recent years, the pace of urbanization has continued to accelerate, and with the emergence of more and more high-rise buildings, the demand for central air conditioning has increased significantly. Generally, the water vapor generated during air conditioning operation quickly condenses into condensed water. However, during actual use, the temperature of the air conditioner surface is often lower than the air dew point, resulting in an increasing amount of condensed water.

[0003] Atriums are large, densely populated spaces. They are a unique way to create a sense of isolation and integration with the exterior space in public buildings such as shopping malls, supermarkets, and offices. They integrate the building's interior with the natural surroundings. They are typically topped with a lightweight, grid-structured, skylight glass roof. While this skylight glass structure creates a bright and airy interior, it also significantly increases ventilation and air conditioning energy consumption. Buildings with conventional glass roofs are particularly vulnerable to high summer temperatures, as they absorb significant amounts of solar radiation. This increases the indoor air conditioning load and severely impacts air conditioning effectiveness, leading to significant condensation in the air conditioning units.

[0004] However, the traditional method of treating central air conditioning condensate is to directly discharge it into the sewer system as waste water, resulting in ineffective and rational utilization of low-temperature cold water resources. Therefore, recycling condensate as a low-temperature auxiliary cooling source or auxiliary water has considerable benefits and application prospects. Summary of the Invention

[0050] In order to facilitate the understanding of the present invention, the technical solutions and advantages of the invention are further described in detail below in conjunction with the accompanying drawings and embodiments. Any mechanism or method not described in detail in the present invention may refer to the prior art. The specific structure and characteristics of the present invention are described below in an illustrative manner, which should not constitute any limitation to the present invention. At the same time, any of the technical features mentioned below (including implicit or disclosed), as well as any technical features directly displayed or implied in the figures, can be further combined or deleted between these technical features to form more other embodiments that may not be directly or indirectly mentioned in the present invention. Preferred embodiments of the present invention are shown in the accompanying drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thoroughly and comprehensively understood.

[0051] In the operating principle of a typical air conditioning refrigeration cycle, a low-temperature, low-pressure gaseous refrigerant enters the compressor, becoming a high-temperature, high-pressure gaseous refrigerant. It then enters the air-cooled condenser, exchanges heat with the outdoor air, and cools and condenses into a high-temperature, high-pressure liquid refrigerant. The expansion valve throttles and reduces the pressure, turning it into a low-temperature, low-pressure wet steam. The liquid refrigerant in the wet steam evaporates in the evaporator, absorbing heat and cooling the indoor air, achieving a cooling effect. For air conditioning systems with high variable refrigerant flow rates, the evaporator is typically placed indoors, and the refrigerant evaporation temperature is usually lower than the dew point of the indoor air, producing condensate. However, the traditional method of treating condensate in central air conditioning is to directly discharge the condensate as waste water into the sewer system, resulting in a waste of water and cooling capacity, and failing to effectively and rationally utilize low-temperature cold water resources. Therefore, recycling condensate as a low-temperature auxiliary cooling source or auxiliary water has considerable benefits and application prospects.

[0052] To this end, the present invention provides a cooling system for recycling air conditioning condensate, used for cooling and cleaning the glass exterior enclosure 700. The cooling system includes a condensate recovery pipeline 100, a low-temperature water storage tank 200, a normal-temperature water storage tank 300, a spray pipeline 400, and an atomization pipeline 500. The condensate recovery pipeline 100 is connected to the air conditioning unit 600 to collect condensate generated by the air conditioning unit. The low-temperature water storage tank is connected to the condensate recovery pipeline. The normal-temperature water storage tank is connected to the low-temperature water storage tank. The spray pipeline 400 includes a spray pump 410 and a spray nozzle 420. The spray pump is connected to the low-temperature water storage tank and the normal-temperature water storage tank via pipes, respectively. The spray pipeline is configured to transport water from the low-temperature water storage tank or the normal-temperature water storage tank to the spray nozzle via the spray pump, so that the water is sprayed onto the surface of the glass exterior enclosure through the spray nozzle. The atomizing pipeline 500 has an atomizing pump 510 and an atomizing nozzle 520, and the atomizing pump is connected to a low-temperature water tank and a normal-temperature water tank through pipelines respectively; the atomizing pipeline is configured to transport water from the low-temperature water tank or the normal-temperature water tank to the atomizing nozzle through the atomizing pump, so as to spray the water onto the surface of the glass outer protective structure through the atomizing nozzle.

[0053] Specifically, the applicant's research found that the temperature of air-conditioning condensate water in the central air-conditioning system is generally between 10 and 15°C. In theory, air-conditioning condensate is pure water. Even if impurities are mixed in the air, the hardness of condensate water is lower than that of municipal water supply. Therefore, the use of condensate water can greatly reduce the surface scale of the glass outer protective structure, and has a good effect in spray cooling and atomization cooling.

[0054] Combine Figure 3 It can be seen that the glass outer enclosure structure can be a glass curtain wall, a glass roof, etc. In terms of specific structural design, the glass outer enclosure structure can be a single-layer glass structure, or a double-layer insulating glass structure, etc.

[0055] In the present invention, the condensate recovery pipeline is connected to the condensate drain outlet of the air conditioning unit to collect the condensate generated during the operation of the air conditioner. The pipeline should be made of corrosion-resistant materials (such as stainless steel or PVC) to ensure that the condensate can flow smoothly into the low-temperature water storage tank.

[0056] In some implementations, a low-temperature water storage tank is used to store condensate. Its capacity should be designed based on the condensate production of the air conditioning units and the water demand of the glass envelope. The low-temperature water storage tank should have insulation to reduce heat absorption and maintain a low water temperature.

[0057] In some implementations, a normal-temperature water tank is connected to a low-temperature water tank for backup water storage. In one implementation, the normal-temperature water tank receives excess water from the low-temperature water tank. When the low-temperature water tank is nearly full, water is pumped from the low-temperature water tank to the normal-temperature water tank, allowing the low-temperature water tank to continuously store low-temperature condensed water. The capacity of the normal-temperature water tank should match that of the low-temperature water tank to ensure system stability. The normal-temperature water tank should be positioned to facilitate water transfer to and from the low-temperature water tank. For example, the low-temperature water tank should be positioned higher than the normal-temperature water tank to allow for direct gravity water transfer.

[0058] In some embodiments, the spray pipeline includes a spray pump and multiple spray nozzles. The spray pump is connected to a low-temperature water tank and a normal-temperature water tank through pipes to provide power for spraying. The spray pipeline transports water from the low-temperature or normal-temperature water tank to the spray nozzle through the spray pump, and the spray nozzle sprays water on the surface of the glass outer envelope structure for cleaning and cooling. Multiple spray nozzles form a multi-point spray to ensure that the entire surface of the glass outer envelope structure is covered to form a water film on the surface of the glass outer envelope structure for cooling. Surface water film cooling refers to water being sprayed on the surface of the glass outer envelope structure through a spray device to form a layer of flowing water film, which uses convection heat transfer and a small amount of evaporation heat absorption to take away the heat of the glass outer envelope structure. Convection heat transfer occurs between the flowing water film and the glass surface, transferring the heat from the glass surface to the water. Due to the large specific heat capacity of water, it can absorb a large amount of heat.

[0059] In some preferred embodiments, the optimal spray flow rate of the water in the spray pipeline is 1.3 to 1.6 m 3 When the water film thickness is 1-1.2 mm and the flow rate is high, the water film has a good cooling effect and a certain cleaning function. The water film partially evaporates during its flow, absorbing a large amount of heat, further reducing the temperature of the glass surface. Surface water film cooling can effectively reduce the temperature of the glass envelope and alleviate thermal stress caused by high temperatures on the glass surface. By optimizing the design of the spray pipeline, adopting a multi-point spray method, and precisely controlling the spray flow rate and water film thickness, it is possible to achieve both cleaning and cooling effects on the glass envelope.

[0060] In some embodiments, the atomization circuit includes an atomization pump and multiple atomizing nozzles. The atomizing pump is connected to a low-temperature water tank and a normal-temperature water tank via pipes, providing power for the atomization operation. The atomization circuit transports water from the low-temperature or normal-temperature water tank to the atomizing nozzles via the atomizing pump. The atomizing nozzles atomize the water and spray it onto the surface of the glass exterior envelope, forming a fine layer of water mist for cooling. The atomization circuit should be designed for multi-point atomization to ensure coverage of the entire surface of the glass exterior envelope. The selection of atomizing nozzles should be optimized based on the area of ​​the glass surface and the cooling requirements to achieve uniform atomization.

[0061] In the present invention, the spray pipeline and the atomization pipeline cooperate to achieve the following functions:

[0062] (1) Water mist evaporation absorbs heat and cools down: The atomizing nozzle sprays low-temperature condensed water into fine water mist. When the water mist evaporates on the glass surface and in the surrounding air, it absorbs a large amount of heat, thereby reducing the temperature of the glass surface and the surrounding environment.

[0063] (2) Water mist sunshade barrier: The atomized water mist forms a thin layer of water mist on the glass surface, which can reflect and scatter part of the sunlight, reduce the direct solar radiation to the glass surface, and thus reduce the temperature of the glass surface.

[0064] (3) Spraying water film to cover and insulate: The spray nozzle sprays water evenly on the glass surface, forming a continuous water film. The water film removes heat from the glass surface through convection heat transfer and evaporation heat absorption. At the same time, the water film itself also acts as a heat insulator, reducing the heat transfer from the glass surface to the room.

[0065] Atomized water mist and spray water film cool the glass without blocking light, maintaining its translucency. The system's design ensures that cooling measures do not affect the glass's lighting performance. Through its multi-functional design, the cooling system effectively cools the glass envelope while maintaining the glass's brightness and transparency.

[0066] In some specific implementations, such as Figure 3 As shown, the spray nozzles and the atomizing nozzles are both deployed above the surface of the glass outer envelope structure. The spray directions of the spray nozzles and the atomizing nozzles are inclined and directed toward the surface of the glass outer envelope structure.

[0067] The operating logic of the cooling system of the present invention includes:

[0068] 1. Condensate collection: The condensate generated when the air-conditioning unit is running flows into the low-temperature water storage tank through the condensate recovery pipeline.

[0069] 2. Spray Cleaning and Cooling: When the glass enclosure needs to be cleaned, the spray pump activates, pumping water from a low-temperature or room-temperature water tank to the spray nozzles. The spray nozzles evenly spray the water onto the glass surface, removing dust and dirt through the flushing action of the water flow while also removing some heat, achieving the dual effects of cleaning and cooling.

[0070] 3. Atomization: When cooling the glass envelope, the atomizing pump activates, pumping water from a low- or room-temperature water tank to the atomizing nozzle. The nozzle atomizes the water and sprays it onto the glass surface, forming a fine mist. As the mist evaporates from the glass, it absorbs heat, lowering the surface temperature.

[0071] It is understandable that cleaning the glass envelope primarily relies on the spray piping in the cooling system. Cooling the glass envelope can be achieved by using either a single spray piping system, a single atomizing system, or a highly efficient cooling combination of both.

[0072] In summary, the present invention is based on the recovery and reuse of air-conditioning condensate. The low-temperature condensate generated by the air-conditioning unit is collected into a low-temperature water storage tank for storage through a condensate recovery pipeline. On the one hand, the condensate in the low-temperature water storage tank is transported to the nozzle by a spray pump through a spray pipeline and sprayed onto the surface of the glass outer enclosure structure, which can achieve cleaning or cooling; on the other hand, it is transported to the atomizing nozzle by an atomizing pump through an atomizing pipeline and sprayed on the surface of the glass outer enclosure structure. The present invention uses low-temperature condensate in the glass outer enclosure structure, and the cooling system has multiple functions of water mist evaporation to absorb heat and cool down, water mist sunshade barrier, and spray water film covering and insulation, which can achieve the purpose of improving the indoor air-conditioning effect and reducing the energy consumption of the air-conditioning system without affecting the bright and transparent effect that the lighting glass structure brings to the indoor space in the architectural shape.

[0073] The entire system of this invention achieves efficient utilization of condensed water, solving the cleaning and cooling issues of the glass envelope while also achieving energy conservation and environmental protection. The spraying function of the spray pipe effectively removes dust and dirt from the surface of the glass envelope. The synergistic effect of the spray pipe and atomizing pipe effectively achieves automatic cooling of the glass envelope, reducing the temperature of the hot air on the outer surface of the glass envelope. This also further increases the heat transfer resistance of the glass, reduces solar radiation heat entering the room, and reduces the cooling load of the air conditioner.

[0074] In a preferred embodiment, the outer peripheral walls of the condensate recovery pipeline, the spray pipeline and the atomization pipeline are all wrapped with a flexible foam rubber-plastic tube shell or a glass wool tube shell, and the thickness of the flexible foam rubber-plastic tube shell or the glass wool tube shell is not less than 10 mm.

[0075] The outer walls of the condensate recovery pipeline, spray pipeline and atomization pipeline are wrapped with flexible foam rubber-plastic pipe shells or glass wool pipe shells. Both materials have good thermal insulation properties. The flexible foam rubber-plastic pipe shell is a closed-cell elastic material with the characteristics of softness, bending resistance, cold resistance, heat resistance, flame retardancy, waterproofness, and low thermal conductivity, which can effectively reduce heat transfer. The glass wool pipe shell is a fibrous thermal insulation material with good thermal insulation, sound absorption and fire resistance, which can effectively reduce the heat loss of the pipeline. The thickness of the flexible foam rubber-plastic pipe shell or glass wool pipe shell shall not be less than 10mm. This thickness requirement is based on a comprehensive consideration of the thermal insulation effect. The thickness of 10mm can provide a sufficient thermal insulation layer to effectively reduce the heat loss of condensate or cold water in the pipeline during transportation, ensuring that the water temperature can still maintain a low temperature when it reaches the use end.

[0076] In a preferred embodiment, the condensate recovery pipeline has a primary filter, a secondary filter, a fifth electric valve and a condensate inlet pump, and the primary filter, the secondary filter, the fifth electric valve and the condensate inlet pump are arranged in sequence along the water inlet direction of the condensate recovery pipeline.

[0077] These components are arranged sequentially along the inlet direction of the condensate recovery pipeline, forming a highly efficient filtration and transport system. The primary and secondary filters are designed to effectively remove impurities and contaminants from the condensate, ensuring that the water entering the low-temperature water storage tank meets the required quality. By installing the primary and secondary filters, the fifth electric valve, and the condensate inlet pump in the condensate recovery pipeline, the quality of condensate recovery and the operational stability of the system are effectively improved. The dual filtration design of the primary and secondary filters ensures the cleanliness of the condensate. The fifth electric valve controls whether condensate enters the low-temperature water storage tank. Opening and closing the electric valve allows for maintenance and cleaning of the condensate recovery pipeline. For example, when cleaning the primary or secondary filters, the fifth electric valve can be closed, directing the condensate into a bypass line without disrupting the normal operation of the entire system. The condensate inlet pump pumps filtered condensate from the recovery pipeline to the low-temperature water storage tank. The inlet pump should be designed based on the condensate flow rate and head requirements to ensure stable condensate transport.

[0078] In a preferred embodiment, the primary filter is a filter having a PP cotton filter element, a wound filter element or a stainless steel mesh; the secondary filter is a filter having a granular activated carbon filter element or a carbon rod filter element.

[0079] The primary filter primarily removes large particles of impurities, such as dust, sand, and iron filings, from the condensate. If these impurities enter the downstream system, they can cause pipe and nozzle blockages. The secondary filter primarily removes fine particles, odors, and organic matter from the condensate. These fine impurities can affect the proper operation of the shower and atomizing nozzles.

[0080] In a preferred embodiment, the low-temperature water storage tank 200 includes a stainless steel box body, and the outer surface of the stainless steel box body is covered with a polyurethane composite insulation board 210, and the thickness of the polyurethane composite insulation board is not less than 40 mm. The stainless steel box body has good corrosion resistance and mechanical strength, which can effectively protect the condensed water inside the water storage tank from the influence of the external environment, while ensuring the service life of the water storage tank. The outer surface of the stainless steel box body is covered with a polyurethane composite insulation board. The polyurethane composite insulation board is a high-performance insulation material with excellent thermal insulation performance, waterproof performance and mechanical strength. The thickness of the polyurethane composite insulation board is not less than 40 mm. This thickness requirement is based on strict consideration of the insulation effect. The thickness of 40 mm can provide a strong insulation layer, effectively reducing the heat exchange between the condensed water in the water storage tank and the external environment, ensuring that the condensed water maintains a low temperature in the low-temperature water storage tank. Insulation board of this thickness can significantly reduce the heat transfer rate and reduce the temperature rise of the condensed water.

[0081] In one specific implementation, a polyurethane composite insulation board comprises, from top to bottom, a cement fiberglass mat, a flame-retardant polyurethane adhesive applied to the cement fiberglass mat, and a rock wool board attached to the flame-retardant polyurethane adhesive. The rock wool board is foamed to form a polyurethane board, which is then covered with the cement fiberglass mat. In this specific implementation, the polyurethane composite insulation board utilizes a multi-layered design, combining the advantages of cement fiberglass mat, flame-retardant polyurethane adhesive, rock wool board, and polyurethane board to achieve excellent thermal insulation and waterproof properties. This insulation board not only effectively reduces heat transfer but also exhibits excellent weather resistance and environmental friendliness.

[0082] In a specific implementation, the cooling system includes:

[0083] The controller is connected to the spray pump and the atomizing pump respectively, and the controller detects the water level values ​​of the low-temperature water storage tank and the normal-temperature water storage tank respectively;

[0084] Among them, when the water level value of the low-temperature water tank is lower than the preset water level value, the controller disconnects the low-temperature water tank from the spray pipeline and the atomization pipeline, and switches the normal temperature water tank to supply water to the atomization nozzle and the spray nozzle.

[0085] Specifically, the controller's control logic is based on real-time monitoring of the water level. When the water level in the low-temperature water tank is higher than the preset level, the controller maintains connectivity between the low-temperature water tank and the sprinkler and atomizer lines, ensuring normal spraying and atomization operations. However, when the water level in the low-temperature water tank falls below the preset level, the controller performs a series of switching operations. First, the controller disconnects the low-temperature water tank from the sprinkler and atomizer lines to prevent the low-temperature water tank from affecting system operation. Subsequently, the controller switches to the normal-temperature water tank, causing it to deliver water to the atomizer and sprinkler nozzles, thereby ensuring the continued operation of the cooling system.

[0086] Through the controller's intelligent management, the cooling system automatically responds to water level changes without manual intervention, enhancing operational intelligence. The controller's automatic switching function ensures that if the low-temperature water tank's water level is insufficient, the system promptly switches to the normal-temperature water tank, avoiding system downtime due to insufficient water levels and ensuring stable system operation.

[0087] In one specific implementation, the low-temperature water tank is equipped with a high water level sensor and a low water level sensor, which are respectively arranged vertically on the inner wall of the low-temperature water tank. A first electric valve is provided in the pipe connecting the spray pump to the low-temperature water tank, and a second electric valve is provided in the pipe connecting the spray pump to the normal-temperature water tank. A third electric valve is provided in the pipe connecting the atomizer pump to the low-temperature water tank, and a fourth electric valve is provided in the pipe connecting the atomizer pump to the normal-temperature water tank. A controller is respectively connected to the high water level sensor, the low water level sensor, the first electric valve, the second electric valve, the third electric valve, and the fourth electric valve. The controller is configured to command the opening and closing of the first, second, third, and fourth electric valves based on the water level values ​​of the high and low water level sensors.

[0088] (1) Regarding the water level sensor configuration of the low-temperature water tank: The low-temperature water tank is equipped with a high water level sensor and a low water level sensor, which are respectively arranged on the inner wall of the low-temperature water tank. The high water level sensor is used to detect whether the water level has reached the upper limit of the water tank, while the low water level sensor is used to detect whether the water level has dropped to the lower limit of the water tank. Through these two sensors, the controller can monitor the water level in the low-temperature water tank in real time, ensuring that the water level always remains within a reasonable range, and avoiding system operation problems caused by excessively high or low water levels.

[0089] (2) Regarding the water level sensor configuration of the normal temperature water tank: The normal temperature water tank is equipped with a high water level sensor and a low water level sensor. These two sensors are respectively arranged on the inner wall of the normal temperature water tank. Their functions are the same as those of the water level sensor of the low temperature water tank.

[0090] (3) Valve configuration:

[0091] First electric valve: The pipeline connecting the spray pump and the low-temperature water storage tank is equipped with a first electric valve. This valve controls the spray pump to pump water from the low-temperature water storage tank.

[0092] Second electric valve: The pipeline connecting the spray pump and the normal temperature water storage tank is equipped with a second electric valve. This valve controls the spray pump to pump water from the normal temperature water storage tank.

[0093] The third electric valve: The pipeline connecting the atomizing pump and the low-temperature water storage tank is equipped with a third electric valve. This valve controls the atomizing pump to pump water from the low-temperature water storage tank.

[0094] The fourth electric valve: The pipeline connecting the atomizing pump and the normal temperature water storage tank is equipped with a fourth electric valve. This valve controls the atomizing pump to pump water from the normal temperature water storage tank.

[0095] In the cooling system, the controller monitors the water level in the low-temperature water tank, enabling intelligent control of the spray and atomization lines. When the low-temperature water tank level falls below a preset value, the controller automatically switches to the normal-temperature water tank, ensuring stable system operation and effective cooling.

[0096] In some preferred implementations, the cooling system includes:

[0097] Multiple temperature sensors, the temperature sensors are used to collect the outdoor temperature value of the environment where the glass outer enclosure structure is located;

[0098] Several rainfall sensors and temperature sensors are used to detect rainfall information in the environment where the glass exterior enclosure structure is located;

[0099] The controller is connected to multiple temperature sensors and rainfall sensors respectively, and is configured to perform automatic cooling steps according to outdoor temperature values ​​and rainfall information.

[0100] In this invention, temperature sensors are used to collect the outdoor temperature of the environment surrounding the glass envelope. These sensors monitor ambient temperature changes in real time and provide accurate temperature data to the controller. Multiple temperature sensors should be distributed at different locations within the glass envelope to ensure that the collected temperature data fully reflects ambient temperature changes.

[0101] In the present invention, rainfall sensors are used to detect rainfall information in the environment where the glass exterior enclosure structure is located. These sensors can monitor rainfall conditions in real time and provide accurate rainfall data to the controller.

[0102] In some implementations, the automated cooling step may include the following steps:

[0103] Step 1: Get outdoor temperature and rainfall information.

[0104] Specifically, the controller obtains the outdoor temperature value of the environment where the glass outer enclosure structure is located through the temperature sensor. The controller obtains rainfall information through the rainfall sensor, and the rainfall information specifically refers to whether there is rainfall in the outdoor environment.

[0105] Step 2: Determine whether cooling is necessary.

[0106] Specifically, the controller compares the outdoor temperature value with a preset temperature threshold value. If the outdoor temperature value exceeds the preset temperature threshold value, the controller determines that a cooling step needs to be initiated.

[0107] At the same time, the controller determines whether to adjust the cooling strategy based on the rainfall information. Specifically, when the rainfall information is obtained from the rainfall sensor, the sprinkler pipe and the atomizer pipe are closed. It is understandable that when there is rainfall, the sprinkler pipe and the atomizer pipe are closed to avoid wasting water resources.

[0108] Step 3: Perform cooling operation.

[0109] In specific implementation, if cooling is required, the controller selects the appropriate cooling method based on the outdoor temperature value:

[0110] Use the spray pipeline alone: ​​If the outdoor temperature is high, the controller starts the spray pump, first draws water from the normal temperature water tank, and sprays water onto the glass outer protective structure through the spray nozzle to form a water film for cooling.

[0111] Use the atomization pipeline alone: ​​If the outdoor temperature is high, the controller starts the atomization pump, preferentially draws water from the normal temperature water tank, and sprays it onto the glass outer protective structure through the atomization nozzle, using the evaporation of water mist to absorb heat for cooling.

[0112] The spray pipeline and the atomization pipeline work together: if the outdoor temperature is high, the controller starts the spray pump and the atomization pump at the same time, giving priority to drawing water from the low-temperature water tank, and achieving efficient cooling through the dual methods of spraying and atomization.

[0113] like Figure 2 As shown, the present invention provides a control method for a cooling system based on the above-mentioned recycling and utilization of air conditioning condensed water, the control method comprising the following automated cooling steps:

[0114] S100: Acquire multiple outdoor temperature values ​​and calculate an average temperature value.

[0115] S200: When the average temperature value is greater than a first temperature threshold, instruct the spray pipeline to operate or instruct the spray pipeline to operate.

[0116] In a specific implementation, a first preset strategy is invoked to instruct the sprinkler or spray pipeline to operate. Specifically, the first preset strategy includes a water allocation, wherein the water allocation is sequentially arranged as a normal temperature water tank, a low temperature water tank, and a municipal water supply. According to the first preset strategy, the sprinkler or spray pipeline first draws water from the normal temperature water tank in the water allocation.

[0117] S300: When the average temperature value is greater than a second temperature threshold, instruct the spray pipeline and the mist pipeline to operate simultaneously, and the second temperature threshold is greater than the first temperature threshold.

[0118] In a specific implementation, a second preset strategy is called to instruct the spray pipeline to operate and the spray pipeline to operate simultaneously. Specifically, the second preset strategy includes water configuration for the spray pipeline and water configuration for the spray pipeline.

[0119] The water supply for the sprinkler pipes is configured as a normal temperature water tank and municipal water supply in that order. The water supply for the spray pipes is configured as a low temperature water tank and municipal water supply in that order.

[0120] In specific implementation, the spray pipeline follows the second preset strategy, first drawing water from the low-temperature water tank in the spray pipeline water configuration. When the low water level sensor of the low-temperature water tank is triggered, the spray pipeline switches to drawing water from the municipal water supply.

[0121] In specific implementation, the spray pipeline follows the second preset strategy, first drawing water from the normal temperature water tank in the spray pipeline water configuration. When the low water level sensor of the normal temperature water tank is triggered, the spray pipeline switches to drawing water from the municipal water supply.

[0122] The second preset strategy ensures that, under high-temperature conditions, the system achieves rapid and efficient cooling through the coordinated use of spray and mist, combined with the prioritization of low-temperature condensate. Effective insulation ensures that the low-temperature water tank retains the low-temperature condensate, ensuring that the spray and mist systems utilize low-temperature water sources even in high-temperature conditions, resulting in more efficient cooling. Furthermore, intelligent water source switching ensures stable system operation and efficient resource utilization.

[0123] The above embodiments are only preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. For ordinary technicians in this field, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the attached claims and their equivalents.
