ABSTRACT:
A combination air conditioning and fire protection system for a building including a heat exchanger through which fluid may pass under pressure, a fluid conditioning unit operable to bring fluid to a desired temperature for passing through the heat exchanger, and fluid supply and return conduits interconnecting the heat exchanger and fluid conditioning unit for circulating fluid therebetween. The supply and return conduits have discharge heads spaced therealong which are openable in case of fire to discharge fluid therefrom to extinguish a fire in the vicinity of the head. The conduits may include risers in the form of hollow, fluid-tight structural columns which also act to provide structural support for the building. Flow control devices and check valves in the system assure that pressure will be maintained in either the supply or return conduits to discharge fluid onto a fire if the other conduit is damaged and loses pressure.
