Claim 9:
10. A heating, ventilation, and air conditioning (HVAC) system, comprising:
a compressor configured to direct a first heat transfer fluid through a primary heat transfer loop;
a pump configured to direct a second heat transfer fluid through a secondary heat transfer loop;
a heat exchanger fluidly coupled to the primary heat transfer loop and the secondary heat transfer loop, wherein the heat exchanger is configured to receive a flow of the first heat transfer fluid at a first operating pressure and a flow of the second heat transfer fluid at a second operating pressure higher than the first operating pressure; and
a controller configured to:
receive first feedback indicative of a first pressure of the first heat transfer fluid in the primary heat transfer loop and second feedback indicative of a second pressure of the second heat transfer fluid in the secondary heat transfer loop; and
adjust operation of the compressor, the pump, or both, based on the first feedback and the second feedback.
