摘要： A multi-stage pressure distribution and pressure regulation system. The system includes at least one heating and cooling load having a supply side and a return side, a heat source supply system for supplying thermo-fluid to the at least one heating and cooling load, and a booster pumping system including at least one booster pump for transferring the thermo-fluid from the heat source supply system to the supply side of the at least one heating and cooling load for maintaining a predetermined head pressure. The multi-stage system also includes at least one pressure regulating system including at least one pressure reducing and sustaining device for reducing the pressure of the thermo-fluid flowing from the return side of the at least one heating and cooling load and sustaining the pressure at the predetermined head pressure.
