A smart valley electricity thermal storage heating system and method

Abstract

The invention provides an intelligent valley point electricity heat-storage heating system. The intelligent valley point electricity heat-storage heating system comprises a heat exchanger and an electric heater; the heat exchanger is provided with a heating obtaining side water inlet, a heating obtaining side water outlet, a heating side water inlet and a heating side water return port; the system further comprises a heat accumulator and a controller; a water outlet of the electric heater is connected with a water inlet pipe of the heat accumulator through a water pump; a water outlet pipe of the heat accumulator is connected with a water inlet of the electric heater and the heating side water inlet through valves, respectively; the heating side water return port is connected with the water inlet of the electric heater through a valve; thermometers connected with the controller are arranged in the heat accumulator and on the water inlet pipe and the water outlet pipe of the heat accumulator and the pipelines of the heating side water inlet and the heating side water return port, respectively; the controller controls the electric heater to start at a starting moment of the valley point electricity to replenish heat to the heat accumulator, and controls start and stop of the electric heater according to a value of heat in the heat accumulator. Compared with the prior art, the intelligent valley point electricity heat-storage heating system has the advantages of low operating cost, energy saving and low labor cost by replenishing heat by making full use of the valley point electricity.

Description

technical field [0001] The invention relates to a heat storage heating system, in particular to an intelligent valley electricity heat storage heating system and method. Background technique [0002] With the improvement of social environmental protection awareness, more and more small and medium-sized coal boilers will be banned, and the direct use of coal to obtain thermal energy for winter heating will gradually become a history. However, the cost of other alternative energy sources such as natural gas, diesel, and electricity has increased a lot, even ten times, compared to coal, which has greatly increased the cost of heating. At present, there are peak-valley electricity prices in our country, and the significance of implementing peak-valley electricity prices: [0003] <1> For the power grid, it is beneficial to tap the potential and increase the load rate, and the difference between the peak and the valley under the jurisdiction is conducive to the economic an...

Problems solved by technology

However, the existing off-peak electricity heat storage heating system lacks intelligent adjustment of off-peak electricity heat storage time, and it is impossible to predict whether the heat storage in the heat storage device is sufficient or surplus, and there are also disadvantages of energy waste, untimely supply, and cost waste.
