1. A chilled fluid cooling system comprising:

  • a chilled water generating system having an inlet conduit and an outlet conduit for generating chilled water;

    a supply line having first and second ends, the first end being coupled to the outlet conduit to receive the chilled water;

    a variable-flow chilled water distribution system coupled to the second end of the supply line so as to receive all of the chilled water for distributing the chilled water to a load;

    a return line for carrying all of the return water directly from the distribution system to the inlet conduit so that the return water is isolated from the outlet conduit of the generating system whereby a change in flow rate through the distribution system is reflected in a corresponding change in flow rate into the generating system;

    a variable-flow pump in the return line for pumping the return water into the inlet conduit;

    control means for controlling the variable-flow pump responsive to water flow rate through the distribution system; and

    wherein thechilled water generating system includes means for varying its capacity responsive to the flow rate of the return water into the inlet conduit, thereby forming a single-circuit cooling system.
