[0028] The constant temperature and constant pressure cold water device 1 provided by the embodiment is used to regulate and control the water pipe output by the cold water machine, so that the temperature and pressure of the water pipe are maintained within a certain range.

[0029] As Figure 1As shown, a specific embodiment of the constant-temperature and constant-pressure cold water device 1 provided by the present embodiment comprises a cold water device 1, a circulating device, and a pressure supplementing device. The cold water device 1 is used to output cold water. The cold water device 1 has a first pipeline 2 for flowing cold water; the circulating device is connected with the first pipeline 2 and is used to drive the cold water to circulate in the first pipeline; the pressure supplementing device is connected with the circulating device through a second pipeline and is used to adjust the water pressure in the first pipeline 2 in real time by setting the pressure supplementing device; and a control component is electrically connected with the cold water device 1, the circulating driving member 3, and the pressure supplementing water pump, respectively, and is used to control the circulating device and the pressure supplementing device, so as to realize accurate control of the temperature and pressure of the cold water in the first pipeline 2. Specifically, the cold water device 1 is a cold water machine in the prior art.

[0030] By setting the control component, the circulating device, and the pressure supplementing device, the cold water output by the cold water device 1 is automatically adjusted, so that the temperature and pressure of the cold water in the first pipeline 2 are always maintained within a preset range. The automatic adjustment not only improves the stability and reliability of the cold water device 1, but also greatly reduces the need for manual intervention, so that the entire device is more automated.

[0031] As shown in Figure 1 In the present embodiment, the circulating device comprises a circulating driving member 3, which is a circulating water pump. The circulating driving member 3 has an inlet end and an outlet end. The inlet end is in communication with the cold water device 1. By setting the circulating water pump, the cold water can be driven to flow in the first pipeline 2 and enter the inside of the circulating water pump through the inlet end of the circulating water pump. The outlet end is connected with the first pipeline 2. The cold water pressurized by the circulating water pump is sent into the first pipeline 2 and starts to circulate in the first pipeline 2. The operation of the circulating water pump is controlled by the control component. By adjusting the working state of the circulating water pump, the circulating speed of the cold water can be adjusted, so as to further affect the temperature and pressure distribution of the cold water in the first pipeline 2, so that the circulating process of the entire cold water device 1 is more flexible and controllable, which helps to improve the stability and adaptability of the device. It should be noted that, as an alternative embodiment, the circulating device can also comprise a pressure regulating valve.

[0032] As shown in Figure 1 In the present embodiment, a frequency converter 4 is further included, which is electrically connected with the circulating driving member 3 and the control component. The frequency converter 4 can adjust the rotating speed of the circulating water pump. By changing the output frequency, the frequency converter 4 can control the rotating speed of the water pump motor, so as to realize accurate adjustment of the flow rate of the water pump. It should be noted that, as an alternative embodiment, the frequency converter 4 can not be set. The circulating water pump is set as a variable frequency water pump, and the flow rate of the water is directly adjusted by the variable frequency water pump.

[0033] As shown in Figure 1As shown, in the present embodiment, the pressure compensation device includes a pressure compensation drive 5 and a pressure compensation water tank 6. The pressure compensation water tank 6 is provided with a containing cavity for storing water, and the inlet of the pressure compensation drive 5 is in communication with the containing cavity of the pressure compensation water tank 6. The outlet of the pressure compensation drive 5 is in communication with the first pipeline 2 through a second pipeline. The pressure compensation device is used to adjust the water pressure in the first pipeline 2, so as to ensure that the water pressure in the first pipeline 2 is always maintained within a set range. The pressure compensation drive 5 can adopt various forms such as electric pump, pneumatic pump or hydraulic pump, and its selection depends on the specific application scenario and performance requirements. The design of the pressure compensation water tank 6 takes into account the storage capacity and replenishment speed of water, so as to quickly provide sufficient water to the first pipeline 2 when needed, so as to maintain stable water pressure. It should be noted that, as an alternative embodiment, a pressure stabilizing valve can also be included to adjust the pressure in the water pipe. It should be noted that, as an alternative embodiment, an expansion valve can also be provided.

[0034] As shown in the figure, Figure 1 As shown in the present embodiment, a contactor 7 is electrically connected with the pressure compensation drive 5 and the control assembly. The contactor 7 is an electromagnetic automatic switch, which can control the opening and closing of the circuit at a remote place, and can control a large current. By setting the contactor 7, the control assembly can remotely control the pressure compensation water pump. It should be noted that, as an alternative embodiment, the contactor 7 can be used in cooperation with a PLC (programmable logic controller 8), a time relay and other devices to receive control signals to turn on or turn off the circuit, so as to realize remote control and automatic operation of the device.

[0035] As shown in the figure, Figure 1 As shown in the present embodiment, the control assembly includes a controller 8, a temperature sensor 9 and a pressure sensor 10. The temperature sensor 9 and the pressure sensor 10 are arranged on the first pipeline 2, and the controller 8 is connected with the temperature sensor 9 and the pressure sensor 10. The temperature sensor 9 and the pressure sensor 10 are used to monitor the temperature and pressure of the cold water in the first pipeline 2 in real time, and feed back the monitoring data to the controller 8. The controller 8 compares the received monitoring data with the preset temperature and pressure range, and when the monitoring data exceeds the preset range, the controller 8 will issue an instruction to adjust the working state of the circulating device and the pressure compensation device, so as to restore the temperature and pressure of the cold water in the first pipeline 2 to the preset range. It should be noted that, as an alternative embodiment, a flow sensor can also be provided, which is connected with the controller 8.

[0036] As shown in the figure, Figure 1As shown, in the present embodiment, further comprising a display 11, the display 11 is electrically connected with the controller 8. The display 11 is a DCS control interface, which is used to display the temperature and pressure of the first pipeline 2, and personnel can touch the display 11 to adjust the pressure and temperature, and display the adjusted value in real time. This design not only improves the intelligent degree of the equipment, but also makes the operation more intuitive and convenient. Personnel can quickly understand the state of the cold water in the first pipeline 2 by observing the data on the display 11, and make corresponding adjustments according to needs, so as to ensure the stable operation of the equipment. It should be noted that as an alternative embodiment, the display 11 can also not be provided, and the controller 8 can directly detect and control each sensor.
