The user loop is connected to a user end, and the number of user ends is at least two, and at least two user ends are connected in parallel. The liquid that absorbs heat from the heat exchange device flows through each user end along the user loop. During the flow of the liquid in the user loop, heat is exchanged with the outside air. However, after the existing heating pipe network has been used for a long time, especially when the pipe is an iron pipe, the inside of the pipe is prone to rust and some rust residue will be produced. As time goes by, the rust residue in the pipe accumulates, which can easily cause poor circulation or even blockage of the pipe. For this reason, we propose a heating pipe network of a high-temperature carbon dioxide heat pump. Utility Model Content
