Operational envelope control of an hvac component

A non-transitory, computer-readable medium comprising instructions, wherein the instructions, when executed by a processor, are configured to cause the processor to:

• compare an operation coordinate of a compressor of a heating, ventilation, and air conditioning (HVAC) system with a target region of an operational envelope of the compressor, wherein the operational envelope defines compressor operation coordinates corresponding to a range of suction pressures and a range of discharge pressures of a working fluid, and the operation coordinate is defined by data indicative of a detected suction pressure of the working fluid and a detected discharge pressure of the working fluid;
• control a target speed range of the compressor based on comparison of the operation coordinate with the target region of the operational envelope;
• and
• maintain the target speed range in response to a determination that the operation coordinate transitions from the target region of the operational envelope to a deadband region that is outside of the target region.

A heating, ventilation, and air conditioning (HVAC) system, comprising:

• a compressor configured to compress a working fluid;
• and
• a controller configured to:
• compare an operation coordinate of the compressor with a target region of an operational envelope of the compressor, wherein the operational envelope defines compressor operation coordinates corresponding to a range of suction temperatures and a range of discharge temperatures of the working fluid, and the operation coordinate is defined by data indicative of a first temperature of the working fluid exiting the compressor and a second temperature of the working fluid entering the compressor;
• adjust a target speed range of the compressor in response to a determination that the operation coordinate is within a control region of the operational envelope, wherein the control region is outside of the target region;
• monitor a time value associated with a duration for which the operation coordinate is within the control region;
• and
• suspend operation of the compressor in response to a determination that the time value exceeds a time threshold.
