[0002] In the existing heating technologies, floor heating and radiator heating are usually adopted in the north. When using hot water heating, central heating is usually adopted, 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 and construction cost, but also provides 24-hour heating for all rooms of users. When separate time-sharing heating is carried out 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. Moreover, heating is provided for 24 hours every day in winter, and a heating mode of turning on and off as needed cannot be achieved. There is also heating by the traditional electric air conditioner. The traditional electric air conditioner heats by the principle of a compressor, is greatly affected by the ambient temperature, warms up slowly in extremely cold weather, is not warm, and the air is dry.
