1. A system comprising:
a pressure exchanger (PX) coupled to a motor, wherein the motor is configured to control an operating speed of the PX;
a condenser, wherein an outlet of the condenser is fluidly coupled to a first inlet of the PX;
a first pressure gauge configured to provide first pressure data indicative of a pressure of a fluid of the condenser; and
a first controller configured to cause, based on the first pressure data, the motor to adjust the operating speed of the PX.
