1. A multi-stage pressure distribution and pressure regulation system for heating and air conditioning units, comprising:

  • one or more heating and cooling loads for areas vertically zoned depending on head pressure;

    a heat source supply system for supplying thermo-fluid to the respective heating and cooling loads for the vertically zoned areas;

    one or more booster pumping systems which are provided between the heat source supply system and the respective heating and cooling loads and each of which includes booster pumps for transferring the thermo-fluid from the heat source supply system to the respective heating and cooling loads and pump control valves for maintaining a predetermined head pressure; and

    one or more pressure regulating systems which are installed between output side return lines of the respective heating and cooling loads and the heat source supply system and each of which includes at least one pressure reducing and sustaining device for reducing the pressure of the thermo-fluid outputted from each heating and cooling load and sustaining it at the predetermined head pressure, wherein the head pressure acting in proportion to the heights of stories of a building is distributed in a multi-stage manner within a head pressure range for safe use.
