The invention relates to the technical field of heating, and particularly provides a solar energy, electromagnetic energy and phase-change energy storage coupled heating control system comprising a solar thermal collector, a low-temperature phase-change energy storage water tank, a high-temperature phase-change energy storage water tank, an electromagnetic heater, a heat user side and a PLC. The solar thermal collector communicates with the low-temperature phase-change energy storage water tank through a first circulation pipeline. The low-temperature phase-change energy storage water tank is connected with the high-temperature phase-change energy storage water tank through a heat exchange water return pipe and a conveying pipeline. The high-temperature phase-change energy storage water tank is connected with the heat user side through a second circulation pipeline. The electromagnetic heater is connected with the high-temperature phase-change energy storage water tank through a third circulation pipeline. The solar thermal collector and the electromagnetic heater are connected with the PLC. By means of the heating control system, solar energy and electromagnetic energy are supplied in a stepped manner, it is ensured that the heat supply effect of the heat user side is stable, system operation expenses are extremely low, and the heating system can be safer, can save more energy and is more economical and reasonable.

Description

technical field [0001] The invention relates to the technical field of heating, in particular to a heating control system coupled with solar energy, electromagnetic energy and phase change energy storage. Background technique [0002] The survival and development of human beings are inseparable from the environment. Therefore, rational use of existing resources and protection of the environment are the basis for human beings to continue to thrive. However, with the continuous advancement of my country's urban modernization process, environmental pollution is becoming more and more serious. In northern China, small and medium-sized coal-fired heating boilers are widely used and can be seen everywhere. Although the scale of these boilers is small, the number is large. These boilers consume a lot of energy, have low thermal efficiency, and cause serious smoke pollution. Through the effect of atmospheric circulation, they cause great pollution to the local environment, which is ...

Problems solved by technology

[0004] (1) Coal-fired boilers have problems such as low conversion rate of fuel heat energy, low degree of automation, and serious environmental pollution.

[0005] (2) Gas-fired boiler heating has problems such as low thermal efficiency, unstable temperature rise, unstable heating efficiency, unstable heating effect for users, short service life, high gas consumption per unit area, and low degree of automation.

[0006] (3) Electric heating rod heating has problems such as scaling of the heating rod after long-term operation, direct contact with water and electricity, leakage of electricity, potential safety hazards, low thermal efficiency, no energy saving, low degree of automation, etc.

[0007] (4) Heat pump heating is firstly limited by local geology, water quality, climate and other conditions, and has a certain impact on the surrounding environment. The initial investment is large, the thermal efficiency of the heat pump is unstable when the seasons change, and the degree of automation is low.

[0008] (5) Solar heating has insufficient heat gain in winter, and the system overheats seriously in non-heating seasons; the heat collection efficiency in winter is low; heat energy in non-heating seasons cannot be stored or consumed, which will reduce the service life of equipment and systems; High influence of weather, low degree of automation

[0009] (6) The power consumption of the electromagnetic heater for heating is relatively large, which is uneconomical
