Domestic-hot-water intelligent control system of distributed energy station

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 ...

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
