Village and town heating system based on phase change heat storage and multi-energy complementation

Abstract

The invention discloses a village and town heating system based on phase change heat storage and multi-energy complementation, which comprises a heat source side and a user side, the heat source side comprises a solar heat collection system, a middle-deep layer geothermal heat supply system, an electric heater and a phase change heat storage heat exchange box, the phase change heat storage heat exchange box is provided with two stages, the electric heater and the solar heat collection system are arranged in the first stage, and the electric heater and the middle-deep layer geothermal heat supply system are arranged in the second stage. A first heat storage loop is formed by connecting the two-stage phase change heat storage and exchange box with the two-stage phase change heat storage and exchange box, a second heat storage loop is formed by connecting the two-stage phase change heat storage and exchange box with the second-stage phase change heat storage and exchange box, a geothermal well of a medium-deep geothermal heat supply system is connected with the second-stage phase change heat storage and exchange box to form a third heat storage loop, and the two-stage phase change heat storage and exchange box is connected with a user side to form a first heat supply loop. And the second-stage phase change heat storage and exchange box is connected with the user side to form a second heating loop. The system can meet the requirements that residents in villages and towns adopt large-temperature-difference heating at night and adopt small-temperature-difference heating in the daytime, two kinds of clean energy are adopted for complementation, and continuity and stability of heating can be guaranteed.

Description

technical field

[0001] The invention belongs to the technical field of heating, ventilation and air conditioning, and in particular relates to a village heating system based on phase-change heat storage and multi-energy complementation. Background technique

[0002] The traditional heating system of villages and towns uses the flue gas generated by the stove for heating. Although it meets the heating needs of residents in winter to a certain extent, there are problems of poor continuous heating stability and environmental pollution. With the improvement of the indoor thermal environment requirements of village residents in winter and To protect the environment, it is imperative to make changes to the existing heating forms in villages and towns.

[0003] Due to the production and living habits of residents in villages and towns, people frequently enter and leave the room during the day, so the standard of clothing is that the outdoor activities will not feel cold in a short ...
