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.

Back to the Future

Twenty-five years ago The Last Emperor won the Academy Award, gas was less than a dollar a gallon and the U.S. Department of Energy was establishing new efficiency regulations for the HVAC industry.

At the time, the industry was using reciprocating compressors in 8 SEER systems. Proponents for the new efficiency standards acknowledged the limitations of existing compressors and it was clear we needed a breakthrough technology that could deliver higher efficiency levels.

On November 14, 1987, Copeland officially became the first U.S. manufacturer to produce scroll compressors for use in the residential air conditioning and heat-pump systems. The industry quickly recognized Copeland Scroll™ compressors as the revolutionary leap in technology needed to achieve the efficiency levels required by the government.

The technology that helped revolutionize an industry 25 years ago is still going strong; over this period Emerson has produced 100 million Copeland Scroll compressors in nine manufacturing facilities spanning three continents.

As we have celebrated our milestones these past few months, the most exciting conversations I’ve had with manufacturers and contractors are focused on where we’re going with the future of scroll technology. Copeland Scroll compressors continue to play an important role in improving efficiency in the industry. We see modulating technology as a key part of our present and future strategy to offer high energy efficiency without compromising comfort. And compressor electronics, including Emerson’s innovations, are becoming critical as we look to use the compressor as a sensor to offer enhanced diagnostics, communication and protection capabilities.

I’m proud to have been part of the team that brought Copeland Scroll technology to market. The industry was at a turning point and we knew we had developed something that would change the future of HVAC.

Don’t Let Your Retail Business Get a Flat Tire

Does your car tell you when it’s time for an oil change or if tire pressure is low? Armed with this information, you don’t wait for a major auto “failure” before you act—you use condition based maintenance.

It’s the same for your retail business. Wouldn’t you rather do maintenance based on equipment condition before it deteriorates to the point where it may fail if not serviced?

Condition Based Maintenance can answer questions like
•    Which of my refrigeration systems are operating improperly or inefficiently?
•    Which of my refrigeration systems are leaking refrigerant?
•    How can I implement a better preventative maintenance scheme or optimize maintenance dispatches?
•    Where should I focus my maintenance budget?

The best news about Condition Based Maintenance is that many retailers already have most of the equipment needed installed already. Products like Emerson E2 controllers, Copeland Scroll™ compressors with CoreSense Diagnostics™, temperature and pressure sensors are increasingly being installed as standard equipment in many retail operations today.

Connecting our Condition Based Maintenance software and service architecture is the final step many retailers need to take to ensure they are safely driving their business.

For more information about Condition Based Maintenance, view my presentation from Emerson’s Technology in Action Conference.
