Less is more

For 15 years, The NEWS has presented the Dealer Design Awards, which highlight the latest, most innovative products in the HVACR industry and honor those that exhibit design excellence. This year, we’re pleased to announce that the Copeland Scroll™ Fractional Horsepower Compressor line was recognized with gold distinction in the Refrigeration and Ice Machines category. Innovation and ease of use are among the key design principles that we strive for in all our products. To receive recognition for these efforts is always an honor.

The award is the culmination of three years of research and design aimed at developing a compressor line that met customer and market needs by achieving an ideal balance of improvements in energy efficiency, environmental friendliness, reliability, safety and more.

The fractional horsepower compressors have a capacity range between 0.75 and 1.25 HPand provide the market with an alternative to reciprocating compressors for applications in medium and low temperatures. The platform is built on the following technological improvements:

  • Liquid injection helps reduce compressor stress and meet federal regulatory requirements
  • Hermetic design reduces the potential for refrigerant leaks
  • 70 percent fewer moving parts than reciprocating compressors delivers improved reliability and an extended compressor life
  • Compliance with the low-temperature operational requirements established by the DOE and the EPA
  • Rated for use with new refrigerant alternatives R-448A/449A and existing lower-GWP HFCs like R-407A

Compared to its hermetic reciprocating counterparts, Copeland Scroll is simpler for an OEM to incorporate into new designs without additional engineering, development and component costs. It’s another example of how we’re striving to engineer products that improve customer operations without imposing unnecessary financial or operational strains.

Emerson plans to continue to refine, innovate and optimize our products to help our customers achieve maximum operational reliability and flexibility. With regard to our fractional horsepower compressors, we will continue to make design improvements to help customers address compliance, sustainability and performance concerns across the broad spectrum of refrigerated applications throughout the food supply chain.

The Case for Outdoor Condensing Units

Restaurant and convenience store landscapes are facing unprecedented market pressures and increasing demands to meet consumer expectations. Consumers are seeking fresh, sustainably sourced food offerings from providers that emphasize eco-friendly practices from farm to fork. Pair those demands with pressure to reduce operating expenses while also maintaining regulatory compliance and you have a stressful situation.

Making the move toward outdoor condensing units (OCUs) may be able to alleviate some of that stress. Modern OCUs can help solve a myriad of operational challenges and are emerging as a preferred option for store and enterprise operators.

Compared to legacy OCUs, modern remote systems can deliver annual efficiency improvements of up to 20 percent or more. Modern OCUs can also create a better, more desirable indoor environment for consumers, improving indoor comfort levels by lightening the load on air conditioning (AC) systems, reducing refrigeration noise, and reclaiming space that would be occupied by a centralized rack.

Modern OCUs are engineered to address today’s regulatory challenges as well, maximizing energy efficiencies and meeting the requirements set by the Department of Energy (DOE). These OCUs also utilize low-global warming potential (GWP) refrigerants and keep refrigerant charges to a minimum.

With built-in compressor electronics, modern OCUs provide operators with peace of mind knowing that their equipment is functioning properly and reliably. System faults are immediately communicated to service technicians to help them quickly — and remotely — diagnose conditions and expedite the service process. Advanced diagnostics and smart algorithms, connected to a facility management/control system, provide operators and technicians with early detection alerts, evaluate key performance indicators, help prevent compressor failure and more.

While there are clear and present benefits to using modern OCUs, there are still considerations to be made before making the switch. Physical constraints are typically prevalent when determining whether to invest in OCUs. Some examples of these constraints are: installation in a leased building where drilling holes in the wall/ceiling is prohibited; unachievable access to the outside for remote installation; and difficulty moving equipment in an inflexible layout. There are also cost considerations to be made, such as whether low first costs or lower total cost of ownership are more important.

Sustainability targets, total store energy usage and regulatory compliance are all important factors in the modern refrigeration equation. Modern OCUs can deliver on all these factors, including enhanced reliability, improved installation flexibility, protection against system failures and much more. All of these benefits add up to a lower total cost of ownership compared to other traditional refrigeration methods.

The case for modern OCUs is strong and could take your operation to the next level.

[Webinar Recap] Technological Solutions to Help Modern Refrigeration Challenges

Today’s commercial refrigeration industry is facing a confluence of challenges. Chief among these are a surplus of regulations, a shortage of qualified technicians, and a consumer base demanding fresh, premium quality foods. And while supermarket, restaurant, mixed retail and convenience store operators try to sort out these complexities, they’re also tasked with driving profitability.

Fortunately, commercial refrigeration manufacturers have stepped up their efforts in recent years to develop technologies to help store operators achieve their compliance, sustainability and profitability goals. In our recent E360 Webinar, I discussed the current shape of the regulatory landscape and how operators can leverage these technologies to address a wide range of challenges.

At the heart of the solution is the emergence of component, system and supervisory electronic controls to provide continual monitoring, automated reporting and diagnostics. Combined with the inherent efficiencies of scroll compression technology, these electronics help operators respond to the federal and state regulations that are mandating significant environmental and energy-efficiency improvements.

I explained how these electronics-enabled refrigeration systems and components can be leveraged to help maximize efficiencies through techniques such as capacity modulation and low-condensing operation. The specific ways technology can be used to protect the environment, reduce energy usage and ensure food safety include:

  • Detecting refrigerant leaks and reducing overall system refrigerant charge
  • Performing on-demand controls such as anti-sweat and defrost
  • Monitoring temperature and humidity conditions from farm to fork

The good news for operators is that by adopting refrigeration strategies that utilize these technologies, they can address many of their compliance challenges simultaneously, while protecting profitability. For example, built-in diagnostic capabilities help technicians quickly troubleshoot and resolve system issues before they could lead to food losses. The benefits are not only reduced food shrink and maintenance costs, but much-needed assistance to mitigate technician shortage concerns.

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.

59-Year-Old Finally Retires

You may not think that retiring at 59 is a big deal, but when you are talking about a Copeland™ brand condensing unit, that’s pretty special.  I recently received an email from a retired owner/contractor, Tom Hall from Owen Sound, Ontario inquiring about the age of a Copeland brand condensing unit (“Copelametic”) he has had in is home walk-in for over 41 years!  He rescued it from a meat market all those years ago after a fire consumed the building.  We get these type of inquiries from time to time, and it’s always enjoyable talking with our long time customers and digging into our archives to try to uncover the manufacturing date of the equipment.

To the best of our knowledge this ¼ HP Copelametic condensing unit was built in 1954 meaning it has been in operation for almost 60 years!  Tom recently retired the unit due to the relay finally giving out, but the compressor was still running strong. 

Is anyone in need of a Copelametic compressor replacement Part #HF25I for a 1954 condensing unit?  I have Tom’s number (just kidding). 

It’s great to hear the stories of longevity of our products.  Tell us your best Copeland brand story!  Can you beat Tom’s?
