[0021] Figures 1 to 6 A regenerated water source heat pump optimization scheduling device showing an embodiment of the present invention includes: A heating and pumping device 6, the water inlet of the heating and pumping device 6 is connected with a water inlet pipe 7; the function of the above-mentioned heating and pumping device is to pump water into the storage cylinder and heat the water during the pumping process to increase the temperature of the water. In a specific embodiment, the heating and pumping device is composed of a heater and a liquid pump in series combination; in another specific embodiment, the heating and pumping device includes a liquid pump and a spiral heating pipe arranged at the liquid outlet of the liquid pump.

[0022] A storage cylinder 8, the storage cylinder 8 is arranged below the heating and pumping device 6, and the water outlet of the heating and pumping device 6 is communicated with the upper interface of the storage cylinder 8; the bottom of the storage cylinder 8 is connected with a fixed seat 9; the function of the storage cylinder is to store the hot water from the heating and pumping device, and the volume of the storage cylinder can be determined according to actual use needs. For example, a storage cylinder with a volume of 2 cubic meters to 10 cubic meters can be adopted.

[0023] A conveying assembly 3, the conveying assembly 3 includes a temporary storage tank 303, a conveying pipe 5, and a connecting pipe 301. The conveying pipe 5 communicates the water outlet of the storage cylinder 8 and the water inlet of the temporary storage tank, and one end of the connecting pipe 301 communicates with the water outlet of the temporary storage tank, and the other end of the connecting pipe is connected to the hot water inlet of the hot water demand side; a pressure relief pipe 304 is arranged at the top of the temporary storage tank 303, a pressure relief valve 305 is installed in the pressure relief pipe 304, and a pressure sensor 308 is installed on the temporary storage tank 303; in a preferred embodiment of the regenerated water source heat pump optimization scheduling device, one end of the pressure relief pipe 304 is connected with a fixed rod 306, and a baffle plate 307 is fixedly connected to the end of the fixed rod 306. On the one hand, the setting of the fixed rod and the baffle plate can prevent personnel from accidentally operating the pressure relief valve, resulting in the pressure value of the temporary storage tank being lower than the required value. On the other hand, it can prevent dust from falling into the pressure relief valve and prevent the pressure relief valve from being damaged by external impact.

[0024] The control device 1 receives the output signal of the air pressure sensor 308 and controls the pressure relief valve 305 according to the air pressure value. In a preferred embodiment of the optimized scheduling device for a renewable water source heat pump, the control device 1 is provided with a plug-in interface 2 and a power supply box 12. The plug-in interface 2 connects the external power supply to the power input terminal of the control device 1; the power supply box 12 is electrically connected to the power input terminal of the control device 1. By setting the plug-in interface and the power supply box to supply power to the control device simultaneously, it is possible to avoid the monitoring and control of the control system from failing when there is an accidental power outage of the mains electricity, and improve the stability of the system operation. In Figure 1 and Figure 6 In a preferred embodiment shown in, the control device is further provided with a data transmission interface 13, through which data can be transmitted with an external data source, such as conveniently changing the configuration parameters of the control device.

[0025] In a further preferred embodiment of the optimized scheduling device for a renewable water source heat pump, a solenoid valve 302 is provided on the connecting pipe 301. The solenoid valve 302 is electrically connected to the control device 1, and the control device 1 controls the operating state of the solenoid valve 302 according to the air pressure value. By setting the solenoid valve, it is possible to judge whether the hot water pressure in the temporary storage tank and the connecting pipe is equal to the required pressure of the hot water demand side based on the data of the air pressure sensor. For example, the control device judges whether the air pressure value is between the upper limit of the first air pressure threshold and the lower limit of the first air pressure threshold. If it is within this range, it means that the hot water supply is stable, and the hot water can be supplied to the hot water demand side. At this time, the control device controls the solenoid valve 302 to open.

[0026] In a further preferred embodiment of the optimized scheduling device for a renewable water source heat pump, a sealing valve 309 is installed on the temporary storage tank.

By setting the above-mentioned auxiliary pipe, when only a small amount of pressure relief is temporarily required, the control device controls the pressure relief valve 305 to open and relieve pressure. Since water vapor will be discharged following the pressure relief during pressure relief, a large amount of water source waste will be caused when a large amount of pressure relief is required. At this time, the control device controls the sealing valve to open and relieve pressure through the connected auxiliary pipe.

[0027] In a further preferred embodiment of the optimized scheduling device for a renewable water source heat pump, the control device 1 is provided with a control panel 10 and a display screen 11, and the operating states of the pressure relief valve 305 and the sealing valve 309 are manually controlled through the control panel 10. In another preferred embodiment, the control panel is also used to control the state of the solenoid valve.

[0028] In a further preferred embodiment of the optimized scheduling device for a regenerative water source heat pump, a temperature sensor 4 is installed on the temporary storage tank. The temperature sensor 4 is electrically connected to the control device 1. The control device 1 generates a temperature value based on the signal of the temperature sensor 4 and displays it on the display screen 11. The actual value of the temperature sensor can automatically control the state of the solenoid valve through the control device, or manually control the state of the solenoid valve through the control panel, so as to make the water temperature at the hot water inlet supplied to the hot water demand side meet the water supply requirements.

[0029] The usage method of the optimized scheduling device for the regenerative water source heat pump in the above embodiment is as follows: The water source is introduced into the heating and pumping device 6 through the water inlet pipe 7. The heating and pumping device 6 heats the water. The heated water enters the inside of the storage cylinder 8. As the hot water level in the storage cylinder 8 rises, the hot water enters the inside of the delivery pipe 5 and then flows into the inside of the temporary storage tank 303. The air pressure sensor 308 monitors the internal pressure change of the temporary storage tank 303 in real time and transmits the pressure signal to the control device 1. If the pressure is greater than the set threshold, the control device 1 controls the pressure relief valve 305 to open, and the internal air pressure of the temporary storage tank 303 is released through the pressure relief pipe 304. Open the sealing valve 309 using the control panel 10. As the sealing valve 309 is opened, the hot water enters the return water collection system through the auxiliary pipe 310.

[0030] In the present invention, an air pressure sensor is used to detect the internal air pressure of the temporary storage tank in real time, and the air pressure data can be transmitted to the control device in real time. The control device can convert the signal and display the value through the display screen. When the internal pressure of the temporary storage tank is too high, the pressure relief valve can be opened in time to release the internal pressure; the temporary storage tank can play a role of transfer, effectively avoiding the situation of pipeline explosion caused by the large internal pressure of the pipeline, ensuring the normal operation of the work and reducing potential safety hazards.
