Low-profile Compressors Deliver High Performance and Merchandizing Capacity

Julie Havenar | Director of Integrated Marketing, Cold Chain
Emerson’s Commercial & Residential Solutions Business

Self-contained refrigerated display cases have become essential fixtures in many food retail operations. Whether they’re used as spot merchandisers in larger stores, or as part of a distribution strategy in smaller-format outlets, these stand-alone systems offer merchandising flexibility while helping retailers achieve their sustainability goals. But checking all the boxes on an ever-expanding list of end-user preferences is no small feat for original equipment manufacturers (OEMs). In a recent article that appeared in HVAC Insider, I explored how low-profile compressors are helping self-contained OEMs to address equipment design challenges. You can also view our formatted article here.

Over the past decade, shifting retail market trends and environmental regulations have helped to drive the emergence of self-contained display cases. Not only are these multi-purpose fixtures used in a variety of everyday scenarios, but they have also enabled food retailers to comply with refrigerant regulations and support their broader corporate sustainability initiatives.

Meeting all these end-user requirements presents a unique set of design challenges for OEMs, including a mix of sustainability and practical considerations:

  • Utilize lower-global warming potential (GWP) A1 and A3 refrigerants
  • Achieve high-energy efficiencies and/or ENERGY STAR® certification
  • Maximize the available merchandising space

Balancing design considerations

The low charge refrigerant requirements of self-contained systems make them ideal candidates for R-290 —which has a GWP of 3 — as well also lower-GWP A1 refrigerants such as R-448A and R-449A. To Improve energy efficiencies or achieve ENERGY STAR certification, OEMs have deployed a variety of design strategies, including the use of large-capacity condenser coils. But these coils can take up precious merchandising space in the case itself and can leave less room for other key system components, including the compressor.

As a potential workaround, OEMs have adopted other design strategies such as placing the compressor and/or condensing unit on top of the case itself. Unfortunately, this strategy can create additional design drawbacks:

  • Increasing the overall size of the case
  • Limiting its aesthetic appeal
  • Creating higher noise levels throughout a store

Recent advancements in low-profile compression technology offer a potential solution. By reducing the size of compressors used in these self-contained applications, Emerson is helping OEMs to achieve their customers’ regulatory compliance and sustainability goals — without sacrificing performance, merchandising space or the design aesthetic of their display cases.

Keeping a lower profile

Today, Copeland™ leads the industry in the development of low-profile, fractional and smaller horsepower (HP) scroll and hermetic compressors — in fixed and variable speed options. Our low-profile Copeland hermetic compressor models are ideal for many smaller, medium- and low-temperature, reach-in units and display cases.

Copeland Hermetic CS Compressors Rated for Lower-GWP Refrigerants

VarunGarg_Blog_Image Varun Garg | Manager, Product Management – Refrigeration

Emerson Commercial & Residential Solutions

The Copeland™ Hermetic CS compressor line has been extended for use with leading alternative refrigerants. To learn more about this important update, read our recent E360 product spotlight.

Copeland Hermetic CS compressors are commonly used in self-contained and remote walk-in coolers, as well as in ice, soft serve and frozen carbonated beverage applications. Most recently, we’ve updated this industry-standard compressor platform to qualify for use with modern refrigerant alternatives — which include R-407A, R-448A and R-449A — to offer lower glower warming potential (GWP) while providing the same reliable performance.

Found in a wide range of commercial refrigeration applications, R-404A is one of the most commonly used hydrofluorocarbon (HFC) refrigerants. In recent years, HFCs like R-404A have been targeted for phase-down via global, federal and state regulatory efforts to limit the use of high-GWP refrigerants. Throughout the industry, many operators are actively seeking lower-GWP options to help them achieve regulatory compliance and meet corporate sustainability initiatives.

Many factors must be taken into account when considering how to transition to a lower-GWP alternative refrigerant, including service, maintenance and operational requirements. It’s no surprise that many operators are hesitant to transition to an option that will force them to overhaul their current refrigeration architecture or introduce a new compression platform. Emerson is helping those familiar with the Copeland Hermetic CS compressor line move from R-404A to one of these approved alternatives — without introducing new system complexities.

For those seeking to comply with regulatory targets or meet sustainability objectives, Copeland Hermetic CS compressors are qualified to use R-407A, R-448A and R-449A in medium-temperature applications. This will enable significant GWP reductions compared to R-404A.

R-404A 3,922 GWP
R-407A 2,107 GWP
R-448A 1,273 GWP
R-449A 1,282 GWP

GWP by refrigerant

Retrofit vs. new: considerations
With these new refrigerant qualifications, operators now have the option to retrofit their legacy Copeland Hermetic CS compressors. It’s important to understand that R-407A, R-448A and R-449A are not considered true “drop-in” replacements.

Even though operators can keep the same compression platform, switching from R-404A to one of these lower-GWP options requires adherence to Emerson’s Refrigerant Changeover Guidelines to help ensure optimum system performance. Expansion valve adjustments, proper lubrication and filter changes must be followed per the application engineering bulletin.

For new applications, this newly qualified Copeland Hermetic CS line of compressors grants operators the flexibility of determining which replacement options are best suited to meet their external regulatory requirements and/or internal sustainability initiatives. Emerson recommends consulting its application engineering bulletin or a certified compression expert to help better understand the performance characteristics of each low-GWP refrigerant option.

To learn specific performance ratings of these new refrigerants, please visit the Copeland Online Product Information (OPI) tool. R-448A and R-449A data will be published in February 2019.
