Classification: CPC F  Y | IPC F

Claim 10:
11. A heating, ventilation, and air conditioning (HVAC) system, comprising:
a controller configured to communicatively couple to a plurality of sensors of the HVAC system and to a compressor of the HVAC system, wherein the controller is configured to:
receive, from a first sensor of the plurality of sensors, data indicative of a first pressure of refrigerant within an evaporator of the HVAC system;
receive, from a second sensor of the plurality of sensors, data indicative of a second pressure of refrigerant within a condenser of the HVAC system;
determine a predicted energy level of operation of a compressor of the HVAC system based on the first pressure of refrigerant and the second pressure of refrigerant, wherein operation of the compressor at the predicted energy level is expected to cause liquid droplet flow from the evaporator to the compressor;
determine an actual operating energy level of the compressor; and
limit operation of the compressor based on a determination that the actual operating energy level exceeds the predicted energy level.
