SYSTEM OF AIR CONDITIONING PIPELINE FOR MULTI-STAGE PRESSURE DISPERSION AND PRESSURE REDUCTION, METHOD FOR CONTROLLING PRESSURE OF THE SAME AND HIGH-RISE BUILDING EQUIPPED WITH THE SAME

摘要

PURPOSE: A system of air conditioning pipeline for multi-stage pressure dispersion and pressure reduction, method for controlling pressure of the same and high-rise building equipped with the same are provided to keep inside pressure all over the air conditioning pipeline constant and stable. CONSTITUTION: A system disperses heat pressure, acting in proportion to height of a building, at multiple stages within safe head pressure range and comprises at least one cooling and heating load(400); a heat source supplying system(100); at least one booster pump system(300); and at least one pressure regulating device(600). The cooling and heating load is vertically sectionalized according to head pressure. The booster pump system is placed between the vertically sectionized cooling and heating loads(410,420,430) and comprises booster pumps(PP2); and pump control valves(PCV2). The booster pumps supply heat source of the heat source supplying system to the vertically sectionized cooling and heating loads. The pump control valves keep setup heat pressure. The pressure regulating device is installed between an output side return line of the vertically sectionized cooling and heating loads and the heat source supplying system and comprises a pressure reduction and maintenance devices(PRSD). The pressure reduction and maintenance devices reduce pressure of heat fluid output from the cooling and heating load to keep fixed heat pressure.
