It focuses on the optimization design of the internal thermal and humidity environment, air quality and energy system of buildings. It involves multiple disciplines such as fluid transportation, heat and mass transfer, materials engineering and intelligent control. It uses technologies such as computational fluid dynamics simulation, development of new composite materials and modular prefabrication assembly. Among them, an intelligent adaptive chilled water pipe pre-integrated system refers to a prefabricated chilled water pipe component that integrates a flexible compensation structure and a biomimetic drag-reducing surface. Through the optimization of corrugated geometric parameters, biomimetic microstructure lining and intelligent alignment compensation technology, it solves the fluid loss problem caused by misalignment of traditional pipe installation. Its purpose is to improve the installation efficiency of chilled water transportation system by 55% while reducing turbulence intensity by 40%.
