Pipe characteristics

Ground source heat pump (GSHP) is mainly operated in the underground, through the connection between pipes to form a cycle, so as to absorb or release heat. Therefore, the selection of pipe material is very important. In the design of GSHP system, it is necessary to determine the material selection of GSHP pipe. At present, the main pipe materials on the market are made of ethylene and polybutene. The reason for choosing this material as the pipe material is that the material is relatively stable in the working process, and even bending will not reduce the working efficiency. In addition, this material is produced by hot melting, and its shape and state will be relatively stable, so it is not easy to deform or Therefore, choosing these materials as GSHP pipes can greatly extend the service life of GSHP.
