When using the waste heat steam generated by thermal power plants and other energy sources for heating, central heating is still usually adopted, and the heating mode is non-stop for 24 hours. That is, hot water is centrally generated and transported to each user through pipelines. This way of central hot water heating not only has a large investment cost, but also provides heating to all rooms of users for 24 hours. When separate time-sharing heating is required in a single area or room of a user according to the user's needs, it is difficult to achieve with the central heating method. At the same time, the heat loss of the central heating pipeline reaches 30 - 40%, which will increase energy consumption itself.
