ABSTRACT:
A system for heating and cooling a building is disclosed. A watercooler and a cold-water pump continuously circulates cold water through a fire sprinkler piping system. A waterheater and a hot-water pump circulates hot water through a domestic hot-water piping system. A plurality of fan-coil assemblies located throughout the building may access either the cold water flowing in the fire sprinkler piping system or the hot-water in the domestic hot-water piping system. The fan-coil assemblies include a fan and a coil. Depending upon whether hot water or cold water is flowing through the coil, air circulated by said fan may be heated or cooled for climate control.
