Description

Technical Field

[0001] This application relates to the technical field of return water controllers, and particularly to an energy-saving commercial return water controller. Background Art

[0002] Currently, in a commercial central hot water system, in order to achieve hot water flowing out immediately when used at a remote end, the hot water needs to circulate in the pipeline and then return to the central hot water tank after circulation, which is abbreviated as return water. The return water control mainly has two types: time control and temperature control. Time-controlled return water is to regularly switch on and off the return water pump or return water solenoid valve. Temperature-controlled return water is to detect the temperature at the end of the return water pipe and switch on and off the return water pump or return water solenoid valve according to the set temperature value.

[0003] In the actual application of a commercial central hot water system, time-controlled return water is not very accurate, and more often temperature-controlled return water is adopted. In summer, especially when solar or air energy central hot water units are often installed on the outdoor roof, the temperature at the end of the return water pipe is very high itself due to the influence of the summer sun. At this time, the return water temperature needs to be set at 45°C or even higher to start the return water. Otherwise, the thermostat will misjudge that the return water temperature has reached and will not start the return water, resulting in the indoor hot water pipe network not circulating for a long time and hot water not being discharged. However, when the ambient temperature is very low in winter, if the return water temperature is set too high, the hot water in the pipeline will keep circulating for return water, resulting in large heat loss.

[0004] The above information disclosed in this background art is only used to increase the understanding of the background art of this application. Therefore, it may include prior art that is not known to those of ordinary skill in the art. Utility Model Content

Detailed Embodiment

[0018] The following will further describe the present application in detail Figures 1-3 with reference to the accompanying drawings.

[0019] An embodiment of the present application discloses an energy-saving commercial return water controller. Refer to Figure 1 , which includes a controller main board 1. Connectors 2 are fixed at both ends of the controller main board 1. A solenoid valve 3 is electrically connected to the connector 2. The direction of the fluid can be controlled through the solenoid valve 3, which is convenient for operating the return water. A display screen 4 is installed inside the controller main board 1. An SET key 6 is installed at the bottom of the display screen 4. An F1 key 7 is installed at the bottom of the SET key 6. An adjustment key 8 is installed on one side of the F1 key 7 for performing corresponding temperature settings. Return water temperature sensors 9 and ambient temperature sensors 10 are respectively installed on both sides of the bottom of the controller main board 1. The return water temperature sensor 9 is used to detect the temperature of the return water, while the ambient temperature sensor 10 is used to detect the temperature of the surrounding environment. Connecting wires 5 are connected to both the return water temperature sensor 9 and the ambient temperature sensor 10. When in use, a summer return water temperature and a winter return water temperature are pre-set on the controller main board 1. The surrounding environment temperature is detected by the ambient temperature sensor 10 to judge summer and winter, and different return water setting temperatures are output to switch the solenoid valve 3. When the ambient temperature is greater than 15°C (adjustable), the summer return water setting temperature is output. When it is less than 15°C (adjustable), the winter return water setting temperature is output.

[0020] As Figures 2-3 shown, connectors 13 are installed on both sides of the back wall of the controller main board 1. Activity cavities 11 adapted to the connectors 13 are symmetrically opened on both sides of the back wall of the controller main board 1. Inner sliding grooves 12 are symmetrically provided on the inner wall of the activity cavity 11. Sliding shafts 14 are symmetrically fixed on the outer walls of the mutually approaching ends of the two connectors 13. The sliding shafts 14 are slidably adapted to the inner sliding grooves 12. The two connectors 13 can be slidably adjusted to adjust the appropriate fixing distance. A number of fixing holes 15 are equidistantly opened on the surface of the connectors 13, which is convenient for connecting and fixing to the installation location. And when the two connectors 13 slide away from each other to the edge of the inner sliding groove 12, they can rotate corresponding angles for cooperation and fixing, further enhancing the overall applicability effect and ensuring the stability of the controller main board 1 during use.

[0021] The implementation principle of an energy-saving commercial return water controller in an embodiment of the present application is as follows: When in use, according to the installation requirements of the main control board 1 of the controller, adjust the sliding of the connecting piece 13 in the inner sliding groove 12 to a suitable position. The sliding shaft 14 can also rotate in cooperation to facilitate adjusting the installation distance of the connecting piece 13. Then, fix the connecting piece 13 at the corresponding installation position by passing a screw through the fixing hole 15, thereby completing the positioning of the main control board 1 of the controller. Then, press the SET key 6 to perform the corresponding return water setting. At the same time, press the up and down adjustment keys 8 to adjust the numerical value. Set the default return water temperature in summer to 45 °C and the default return water temperature in winter to 35 °C. Press the F1 key 7 to save and exit. Detect the temperature of the return water through the return water temperature sensor 9 and transmit the corresponding information to the main control board 1 of the controller. In the working state, long press the SET key 6 without releasing it. After 5 seconds, enter the secondary parameter setting state. At this time, press the SET key 6 once to enter the winter-summer conversion temperature, with the default being 15 °C. Press the SET key 6 once again to enter the ambient temperature deviation correction, and the parameter blinks, with the default being 0 °C. At the same time, cooperate to adjust the numerical value. The main control board 1 of the controller detects the ambient temperature through the ambient temperature sensor 10 to judge summer and winter, and outputs different return water setting temperatures to switch the solenoid valve 3. When the ambient temperature is greater than 15 °C (adjustable), output the return water setting temperature in summer. When it is less than 15 °C (adjustable), output the return water setting temperature in winter.
