Discussion on keeping the soil heat balance by zone piping and partition running

With an actual project case, presents the thought of keeping the soil heat balance by zone piping and partition running as far as possible on the premise that the heat charging and discharging quantities are basically balanced. The buried pipe region is divided into three parts, i.e. inner area, middle area and outer area. Compares the operation strategies of traditional and new zoning methods in detail, and analyses the advantages and disadvantages. The results show that the strategy with zone piping and partition running in most area can create a sound energy-saving effect.
