Abstract

An HVAC system for a multi-unit building having a riser stack in flow communication with a single unit HVAC system. The single unit HVAC system has a first heat exchanger thermally connected to the riser stack, a second heat exchanger thermally connected to a fluid distribution system within the unit, and a closed loop fluid flow path extending between the first and second heat exchangers. The first heat exchanger exchanges heat between a riser stack fluid in the riser stack and the closed loop fluid in the closed loop fluid flow path and the second heat exchanger exchanges heat between the closed loop fluid and a distribution fluid of the fluid distribution system.

  3. 3. The multi-unit building HVAC system of claim 1 wherein the closed loop fluid is a liquid and the closed loop fluid flow path utilizes 1-200 L, 2 -100 L or 5-20 L of the closed loop fluid which is at a pressure of 1 - 30 psi or 5-15 psi.
  4. 4. The multi-unit building HVAC system of claim 3 wherein the riser fluid is at a pressure of at least 100 psi.
  5. 5. The multi-unit building HVAC system of claim 1 wherein a floor in a building has at least a first unit and a second unit, the first single unit HVAC system provides temperature modulation to the first unit and a second single unit HVAC system provides temperature modulation to the second unit.
  6. 6. The multi-unit building HVAC system of claim 1 wherein a floor in a building has at least a first unit and the first single unit HVAC system provides temperature modulation to the first unit and the riser stack is exterior to the first unit. - 65 -
  7. 7. The multi-unit building HVAC system of claim 6 wherein the riser is provided interior of a liner conduit.
  8. 8. The multi-unit building HVAC system of claim 1 further comprising a riser leak detector which issues a signal that terminates flow in the riser stack upon a leak in the riser stack being detected.
  9. 9. The multi-unit building HVAC system of claim 8 wherein the riser leak detector comprises at least one of a float switch and a conductivity sensor.
  10. 10. The multi-unit building HVAC system of claim 1 further comprising a closed loop high pressure sensor which issues a signal that terminates flow in the closed loop fluid flow path upon a high pressure condition being detected.
  11. 11. The multi-unit building HVAC system of claim 1 further comprising a closed loop leak detector which issues a signal that terminates flow in the closed loop fluid flow path upon a leak in the closed loop fluid flow path being detected.
  12. 12. The multi-unit building HVAC system of claim 1 further comprising a capacitance leak detector wherein, upon occurrence of a leak, the capacitance leak detector issues a signal that terminates flow in the riser stack if the capacitance leak detector detects a fluid having a capacitance above a present capacitance that is indicative of the riser fluid and the capacitance leak detector issues a signal that terminates flow in the closed loop fluid flow path if the capacitance leak detector detects a fluid having a capacitance below the present capacitance that is indicative of the closed loop fluid.
  13. 13. The multi-unit building HVAC system of claim 1 wherein a floor in a building has at least a first unit, the unit has a first room and a second room, the second heat exchanger provides temperature modulation to the first room and the first single unit HVAC system comprises a third heat exchanger that provides temperature modulation to the second room and the third heat exchanger exchanges heat between the closed loop fluid and the distribution fluid of the fluid distribution system. - 66 -
  14. 14. The multi-unit building HVAC system of claim 1 wherein a floor in a building has at least a first unit and the fluid distribution system comprises a fluid conduit that extends between the second heat exchanger and a room of the first unit
