Claim 0:
1. A heating, ventilation, and air conditioning (HVAC) system, comprising:
a primary heat transfer loop, comprising:
a heat exchanger; and
a compressor configured to direct a first heat transfer fluid along the primary heat transfer loop and through the heat exchanger at a first operating pressure;

a secondary heat transfer loop, comprising:
the heat exchanger; and
a pump configured to direct a second heat transfer fluid along the secondary heat transfer loop and through the heat exchanger at a second operating pressure higher than the first operating pressure; and

a controller configured to receive feedback indicative of a first pressure of the first heat transfer fluid in the primary heat transfer loop, receive additional 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 feedback and the additional feedback.
