Problems solved by technology

The existing large-scale building control system that combines distributed energy stations with domestic hot water brings convenience to users' domestic water use. However, due to the uncertainty of users' water consumption time and water consumption, the system needs to run 24 hours a day to meet the requirements. The user's water demand will inevitably cause the equipment to continue to operate when no user is using it or the water consumption is very small, resulting in a lot of energy and resource waste
In addition, the existing domestic hot water control system is simple in design and relies entirely on manual operation, which cannot meet the needs of existing intelligent control
During the transition season of the energy station, that is, when the energy station is out of service, the control system cannot operate, resulting in system resource occupation and waste of parking

Embodiment 1

[0017] Embodiment 1 of the present invention: as figure 1 As shown, the domestic hot water intelligent control system includes electric hot water boiler 1, electric boiler heat storage pump 2, hot water storage tank 3, primary heating circulation pump 4, domestic water heat storage plate heat exchanger 5, domestic water heat storage Circulation pump 6, high level water tank 7, heat supply plate heat exchanger 8, secondary heat supply circulation pump 9, first valve 14 and second valve 15, also includes control device, liquid level switch 01LS and liquid level measuring sensor 01LT. One end of the electric hot water boiler 1 communicates with the electric boiler heat storage pump 2 through the first valve 14 , and the other end communicates with the high-level water tank 7 . One end of the heat storage tank 3 is connected to one end of the heat supply plate heat exchanger 8 through the primary heat supply circulation pump 4, and the other end of the heat supply plate heat excha...

Embodiment 2

[0019] Embodiment 2: as figure 1As shown, the electric boiler heat storage pump 2, the primary heat supply circulation pump 4, the domestic water heat storage circulation pump 6 and the secondary heat supply circulation pump 9 are composed of two pumps respectively. The control device can automatically accumulate the running time of the pumps, and automatically select the pump with the shorter running time during operation: if one pump fails during operation, the control device will automatically start the other pump; All pumps are set to the automatic remote control position, and the system will automatically select one pump to run according to the program; if one pump fails or is being repaired, the pump control button is rotated to the in place position, and the control device will automatically turn on the other one in the remote control position pump. The control device also controls the liquid level of the high-level water tank 7, and the first electric valve 12 realize...

Embodiment 3

[0020] Embodiment 3: as figure 1 As shown, the automatic heat storage process of the hot water storage tank 3 is divided into two situations.

[0021] 1) When the energy station is in the energy supply season, the energy station ensures the water supply temperature of the second temperature sensor 02TE, and the first regulating valve 10 is automatically controlled and adjusted according to the temperature signal of the sixth temperature sensor 06TE.

[0022] a) When the temperature signal of the sixth temperature sensor 06TE is lower than the normal return water temperature value, it means that the user load is too large, and it is necessary to increase the flow rate of the first regulating valve 10 to the heat exchanger of the domestic water pump room; when the first regulating valve 10 When the heat exchanger of the domestic water pump room is fully opened, if the temperature signal of the sixth temperature sensor 06TE is still lower than the normal return water temperature ...

Abstract

The invention discloses an intelligent control system and particularly relates to a domestic-hot-water intelligent control system of a distributed energy station. The domestic-hot-water intelligent control system is characterized in that one end of an electric hot water boiler is communicated with an electric boiler heat storage water pump through a first valve, and the other end of the electric hot water boiler is communicated with a high water tank; the electric boiler heat storage water pump, a heat storage water tank, a primary heat supply circulation pump, a heat supply plate type heat exchanger and a secondary heat supply circulation pump are sequentially communicated through pipelines, and the heat storage water tank is communicated with the electric hot water boiler through a second valve; the domestic-water heat storage plate type heat exchanger is communicated with the electric boiler heat storage water pump through a domestic-water heat storage circulation pump, a liquid level switch is mounted on the high water tank, and a liquid level measuring sensor is mounted on the heat storage water tank; each equipment above is electrically connected with a control device, and the control device controls the operation of the whole domestic-hot-water intelligent system. The intelligent control system has the advantages that manual operation is not needed, intelligent control of domestic hot water is achieved, and users' living requirements are satisfied while equipment operation energy consumption is lowered greatly.

Description

technical field [0001] The invention relates to an intelligent control system, in particular to a domestic hot water intelligent control system of a distributed energy station. Background technique [0002] Distributed energy station is an energy supply method built on the user side, which can operate independently or in parallel with the grid. It is a system that determines the mode and capacity by maximizing resources and environmental benefits. Distributed energy stations have the characteristics of reasonable energy efficiency, low loss, less pollution, flexible operation, and good system economy. The existing large-scale building control system that combines distributed energy stations and domestic hot water brings convenience to users' domestic water use. However, due to the uncertainty of users' water consumption time and water consumption, the system needs to run 24 hours a day to meet the requirements. The user's water demand will inevitably cause the equipment to ...
