Claim 7:
8. The chiller system of claim 1, comprising a valve disposed in an outlet header configured to receive the refrigerant from a plurality of fan coil units including the fan coil unit, wherein the valve is configured to:
open in response to a free-cooling operation of the chiller system such that the refrigerant is passed from the plurality of fan coil units, through the outlet header, and to the free-cooling circuit;
open in response to a mechanical-cooling operation of the chiller system such that the refrigerant is passed from the plurality of fan coil units, through the outlet header, and to the mechanical-cooling circuit; and
close in response to a hybrid-cooling operation of the chiller system such that a first portion of the refrigerant is passed from a first portion of the plurality of fan coil units, through a first portion of the outlet header, and to the mechanical-cooling circuit, and such that a second portion of the refrigerant is passed from a second portion of the plurality of fan coil units, through a second portion of the outlet header, and to the free-cooling circuit.
