Description

Technical Field

[0001] The invention discloses an intelligent electric heating system which utilizes heating pipes to store energy, and belongs to the field of energy storage electric heating. Background Art

[0002] With the rapid development of my country's economy, environmental pollution is becoming more and more serious. In recent years, we have been committed to the direction of blue sky and white clouds, and vigorously develop coal-to-electricity. The imbalance of time and space on the demand side of electric energy is also very prominent, and energy storage is imperative. Existing energy storage technology cannot make more use of off-peak electricity to ensure 24-hour heating for user rooms to improve user comfort, reduce grid pressure, and achieve energy conservation and environmental protection; and the current water energy storage equipment occupies a large area. Summary of the invention

[0003] In view of the shortcomings of the prior art, the purpose of the present invention is to provide an intelligent electric heating system that utilizes energy storage in heating pipes, so as to solve the problem that the prior art cannot make more use of the heat of off-peak electricity to heat user rooms 24 hours a day to improve user comfort, reduce the pressure on the power grid, achieve energy conservation and environmental protection, and reduce the volume and floor space of water energy storage equipment.

[0004] In order to achieve the above-mentioned purpose, the present invention is realized by the following technical scheme: an intelligent electric heating system using energy storage in a heating pipeline, comprising an electric heating device, an energy storage water pump, an energy storage heating pipeline, an energy storage pipeline thermometer, a terminal heating pipeline, an adjustable water mixing valve, a hot water supply pump, a terminal heating pipeline thermometer, and a radiator. The electric heating device is equipped with an electric heating rod and a water supply and return pipe. When the electricity is low, the electric heating rod is started to heat the energy storage medium water first. The water supply and return pipes are connected to the energy storage water pump and the energy storage heating pipeline to form an energy storage circulation loop so that the energy storage medium water is evenly heated. The adjustable water mixing valve is provided with a hot water inlet interface, a cold water inlet interface and a warm water outlet interface. Its hot water inlet interface is connected to the energy storage heating pipeline through the terminal heating pipeline, and its warm water outlet interface is connected to the hot water supply pump and the radiator in turn through the terminal heating pipeline. The end is connected to its cold water inlet interface to form a terminal heating loop, so that the heated circulating medium water supplies heat to the room for heating the user's room. The radiator is a sheet or pipe that dissipates heat into the user's room.

[0005] Furthermore, the diameter specification of the energy storage heating pipeline needs to refer to the relevant provisions of the "Design Code for Heating, Ventilation and Air Conditioning of Civil Buildings (GB50736-2012)" for heating system pipelines and increase the selection of 2 specification levels, thereby increasing the volume of energy storage medium water in the energy storage circulation loop.

[0006] Furthermore, the outer surface of the energy storage heating pipeline needs to be insulated with thermal insulation materials to reduce heat dissipation to the surrounding environment.

[0007] Furthermore, the energy storage heating pipeline needs to be equipped with an energy storage pipeline thermometer for detecting the temperature of the energy storage medium water inside the energy storage heating pipeline. During use, the temperature of the energy storage medium water inside the energy storage heating pipeline must not exceed the heat storage limit temperature. The heat storage limit temperature setting must be at least 5°C lower than the boiling point of water under the local atmospheric pressure; when the energy storage medium water temperature exceeds the heat storage limit temperature, the electric heating rod must be stopped.

[0008] Furthermore, the adjustable mixing valve needs to have the function of manually or electrically setting the warm water outlet temperature and automatically adjusting the warm water outlet temperature according to the warm water outlet temperature, so as to maintain the temperature of the circulating medium water at the radiator inlet stable.

[0009] Furthermore, the terminal heating pipe needs to be equipped with a terminal heating pipe thermometer to detect the temperature of the circulating medium water inside the terminal heating pipe, and ensure the necessity of the circulating medium water in the terminal heating loop to supply heat to the room during use; when the circulating medium water temperature is less than the set temperature of the warm water outlet of the adjustable mixing valve by less than 5°C, the hot water pump needs to be stopped.

[0010] The present invention discloses an intelligent electric heating system that utilizes energy storage in a heating pipeline. By setting an energy storage heating pipeline, water is heated by an electric heating device as an energy storage medium. The hot water is stored in the energy storage heating pipeline for energy storage for use. An insulation layer needs to be added to the outer surface of the energy storage heating pipeline to prevent heat dissipation to the outside, so as to avoid causing a large heat loss. An adjustable water mixing valve is provided to stabilize the temperature of the circulating medium water in the terminal heating circuit, and the water circulation in the heating circuit is controlled by a hot water pump to start and stop constant temperature heating. The present invention solves the problem that the prior art cannot make more use of the heat of off-peak electricity to heat the user's room 24 hours a day to improve user comfort, reduce the pressure on the power grid, and achieve energy conservation and environmental protection, and reduce the volume and floor space of water energy storage equipment. In particular, the heating needs of factory buildings and small residential areas that cannot be connected to municipal centralized heating are more suitable for setting up energy storage heating pipelines as energy storage supplements, utilizing off-peak electricity energy storage for heating, and reducing the volume and floor space of energy storage equipment.

Further, the outer surface of the energy storage heating pipeline 3 needs to be insulated with thermal insulation materials to reduce heat dissipation to the surrounding environment.
