Compressor Electronics Provide Protection for Adverse Operating Conditions

Many of us are familiar with the metaphor that the compressor is like the heart of an HVAC system.  The “heart” behaves inefficiently with irregular patterns when particular conditions exist within the system that drives the compressor outside of its normal operating parameters.   CoreSense™ technology for Copeland Scroll™ compressors is designed to detect this irregular heart beat much like an EKG monitor does during a visit to the doctor.  Many of the common excursions outside of the operating envelope, like loss of charge, low suction pressure, high discharge pressure, and overcharge, can be detected and ultimately prevented with the proper application of CoreSense technology.  Protecting the compressor and shutting it down before a catastrophic incident saves valuable time and money throughout the service channel.

The following graphic depicts a typical compressor operating envelope for a residential air conditioning application.  The area highlighted in green is where the compressor is designed to operates in the most efficient and optimal way.  Prolonged operation outside this region can lead to significant compressor and system damage.  Four typical operating excursions, the possible causes, and the end of life compressor scenario are denoted around the perimeter of the envelope.  The application of CoreSense technology will proactively detect these excursions and prevent them from causing unwanted damage and costly repairs.
