Description

Technical Field

[0001] This utility model relates to the field of central air conditioning technology, specifically to an energy-saving central air conditioning water pump flow regulation device. Background Technology

[0002] The central air conditioning water system is a water circulation system at the central air conditioning unit level, including a cooling water system and a chilled water / hot water system (for air-cooled systems, only the latter is included). It connects the fan coil units in each room to the chilled / hot water units via pipes to provide cooling and heating. The water system offers flexible layout and good independent adjustability, meeting the needs of complex room layouts for decentralized use and independent operation. Central air conditioning systems experience peak and low-consumption periods, requiring different pump flow regulation methods during these periods, necessitating energy-efficient central air conditioning pump flow regulation devices.

[0003] The existing patent, CN219473909U, entitled "A Flow Regulation Device for a Cooling Water Pump in a Central Air Conditioner," discloses a flow regulation device for a cooling water pump in a central air conditioner. It includes a valve, two sets of connecting pipes bolted to the valve's inlet and outlet, and a control assembly installed outside the valve to control the water flow. The valve is connected to the inlet of the cooling water pump body. A control bolt is provided at the valve's control end. The control assembly includes a mounting frame with a temperature control switch inside. A controller is mounted on the upper surface of the mounting frame, and a motor is electrically connected to the controller's control end. A control gear is provided at the motor's output end. The temperature control switch monitors the temperature inside the central air conditioner, and the controller controls the motor's operation. When the temperature inside the central air conditioner reaches different ranges, the control gear's speed is controlled at different speeds to stabilize the rotating sleeve, further controlling the rotation of the control bolt to control the valve and thus the cooling water flow.

[0004] The aforementioned device controls the motor's operation via a controller. When the temperature inside the central air conditioner reaches different ranges, the control gear is rotated at different speeds to ensure stable rotation of the rotating sleeve. This further controls the rotation of the control bolt to control the valve and thus the cooling water flow. However, when the central air conditioner is operating under high load, the valve's control over the cooling water flow cannot quickly alleviate the load on the central air conditioner, nor can it properly divert the cooling water to reduce pressure, thus failing to adequately meet user needs. To address these issues, a technological innovation is proposed based on the existing water pump flow regulation device. Utility Model Content

[0005] The purpose of this invention is to provide an energy-saving central air conditioning water pump flow regulation device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an energy-saving central air conditioning water pump flow regulation device, comprising a cooler and an inlet pipe, wherein a second return pipe is connected to the lower part of the cooler, and a cold water storage tank is installed below the second return pipe; the inlet pipe is installed at the front end of the cooler, and a hot water storage tank is installed on one side of the upper part of the inlet pipe; a first return pipe is installed below the hot water storage tank; hot water enters the cooler through the inlet pipe, is cooled, and then is sent back to the cooling working cycle of the central air conditioning system from the outlet through a circulating pump.

[0007] Furthermore, a regulating valve is installed at the front end of the cold water storage tank, and a regulating component is installed inside the regulating valve.

[0008] Furthermore, the regulating component includes an regulating plate and a flow plate, and the flow plate is installed at the rear of the regulating plate. The regulating plate and the flow plate rotate relative to each other, and the openings on the regulating plate and the flow plate cover each other, thereby changing the size of the openings and thus changing the flow rate.

[0009] Furthermore, the adjustment plate is equipped with external teeth on its periphery, and the external teeth are welded to the adjustment plate.

[0010] Furthermore, a gear meshes with one side of the external tooth, and a servo motor is installed at the rear end of the gear. The servo motor drives the external tooth to rotate through the gear.

[0011] Furthermore, a circulation pump is installed above the regulating valve, and the circulation pump is threadedly connected to the regulating valve. All valves installed on each pipeline are regulating valves.

[0012] Furthermore, an outlet is installed above the circulating pump, and the outlet is threadedly connected to the circulating pump. The cooler cools the hot water and then sends it out of the outlet through the circulating pump.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: When it is necessary to adjust the flow rate of each pipe, the servo motor drives the external gear to rotate through the gear, the adjusting plate and the flow plate rotate relative to each other, and the openings on the adjusting plate and the flow plate cover each other, thereby changing the size of the openings and thus changing the flow rate. Hot water enters the cooler through the inlet pipe and is cooled, and then is sent back to the cooling working cycle of the central air conditioner from the outlet through the circulation pump. When the central air conditioner is operating at high load, the regulating valves above and below the inlet pipe reduce the flow rate, and the regulating valve near the hot water tank opens a certain channel as needed, so that the hot water is divided into two streams and enters the hot water tank and the cooler respectively. After the cooler cools the hot water, it is sent out of the outlet through the circulation pump. At the same time, the regulating valve on the return pipe 2 opens a certain channel to replenish the water flowing into the hot water tank and ensure that sufficient cooling water participates in the circulation. When the central air conditioner load is reduced to a suitable range, the hot water in the hot water tank enters the cooler through the return pipe 1 and is cooled. The cooled water then enters the cold water tank for storage, maintaining the central air conditioner with sufficient high load capacity.

[0020] like Figure 1As shown, an energy-saving central air conditioning water pump flow regulating device includes a cooler 1 and an inlet pipe 2. A return pipe 2 5 is connected to the lower part of the cooler 1, and a cold water storage tank 6 is installed below the return pipe 2 5. The inlet pipe 2 is installed at the front end of the cooler 1, and a hot water storage tank 3 is installed on one side of the upper part of the inlet pipe 2. A return pipe 4 is installed below the hot water storage tank 3. A circulation pump 7 is installed above the regulating valve 9, and the circulation pump 7 is threadedly connected to the regulating valve 9. An outlet 8 is installed above the circulation pump 7, and the outlet 8 is threadedly connected to the circulation pump 7. Hot water enters the cooler 1 through the inlet pipe 2, is cooled, and then is sent back to the central air conditioning unit through the outlet 8 via the circulation pump 7. During the circulation, when the central air conditioning is operating at high load, the regulating valves 9 above and below the inlet pipe 2 reduce the flow rate. The regulating valve 9 near the hot water storage tank 3 opens a certain channel as needed, so that the hot water is divided into two streams and enters the hot water storage tank 3 and the cooler 1 respectively. After the cooler 1 cools the hot water, it is sent out to the outlet 8 through the circulation pump 7. At the same time, the regulating valve 9 on the return pipe 2 5 opens a certain channel to replenish the water flowing into the hot water storage tank 3, ensuring that sufficient cooling water participates in the circulation. When the central air conditioning load is reduced to a suitable range, the hot water in the hot water storage tank 3 enters the cooler 1 through the return pipe 1 4 for cooling. The cooled water then enters the cold water storage tank 6 for storage, maintaining sufficient high load capacity for the central air conditioning.

[0021] like Figure 2 and Figure 3 As shown, a regulating valve 9 is installed at the front end of the cold water storage tank 6, and a regulating component 10 is installed inside the regulating valve 9. The regulating component 10 includes a regulating plate 1001 and a flow plate 1002, and the flow plate 1002 is installed at the rear of the regulating plate 1001. External teeth 11 are installed around the regulating plate 1001, and the external teeth 11 are welded to the regulating plate 1001. A gear 12 meshes with one side of the external teeth 11, and a servo motor 13 is installed at the rear end of the gear 12. The valves installed on each pipeline are all regulating valves 9. When it is necessary to adjust the flow rate of each pipeline, the servo motor 13 drives the external teeth 11 to rotate through the gear 12. The regulating plate 1001 and the flow plate 1002 rotate relative to each other, and the openings on the regulating plate 1001 and the flow plate 1002 cover each other, thereby changing the size of the openings and thus changing the flow rate.

[0022] Working principle: When using this energy-saving central air conditioning water pump flow regulation device, firstly, all valves installed on each pipeline are regulating valves 9. When it is necessary to adjust the flow of each pipeline, the servo motor 13 drives the external gear 11 to rotate through the gear 12. The regulating plate 1001 and the flow plate 1002 rotate relative to each other, and the openings on the regulating plate 1001 and the flow plate 1002 overlap each other, thereby changing the size of the openings and thus changing the flow. Hot water enters the cooler 1 through the inlet pipe 2 for cooling and then is sent back to the central air conditioning cooling cycle from the outlet 8 through the circulation pump 7. When the central air conditioning is operating under high load, the inlet water... The regulating valves 9 above and below pipe 2 reduce the flow rate. The regulating valve 9 near the hot water storage tank 3 opens a certain channel as needed, so that the hot water is divided into two streams and enters the hot water storage tank 3 and the cooler 1 respectively. After the cooler 1 cools the hot water, it is sent out of the outlet 8 through the circulation pump 7. At the same time, the regulating valve 9 on the return pipe 2 5 opens a certain channel to replenish the water flowing into the hot water storage tank 3, ensuring that enough cooling water participates in the circulation. When the central air conditioning load is reduced to a suitable range, the hot water in the hot water storage tank 3 enters the cooler 1 through the return pipe 1 4 for cooling. The cooled water then enters the cold water storage tank 6 for storage, maintaining the central air conditioning with sufficient high load capacity.
