The pipeline networks design approach for integrated heat and cold supply systems based on absorption chillers has been developed. Within the framework of the approach, following tasks are solved: modeling consumers demand for cooling; hydraulic calculations of district cooling pipeline systems; technical and economic calculations to choose the optimal layout of pipeline systems; heat supply and cold supply systems repair and commissioning works compatibility assessment, and modeling of thermal interaction between permafrost massif and cold supply pipeline. The study of integrated heat and cold supply systems was carried out on the example of a Yakutsk city quarter using the developed approach to determine optimal variant of the system. The simulation results showed that district cooling pipelines can be laid underground with the implementation of measures to ensure preservation of permafrost soil temperature regime.
Key words: integrated energy systems / district cooling / absorption chiller / fancoil / pipeline systems design / hydraulic calculations / permafrost soils
