Introducing Copeland™ Variable Speed Reciprocating Hermetic Compressors for Refrigeration

Derek Langenkamp | Product Manager, Hermetic Reciprocating

Emerson’s Commercial and Residential Solution’s Business

Making equipment design changes to meet increasing energy efficiency standards is nothing new for original equipment manufacturers (OEMs) in the commercial refrigeration space. For quite some time, the medium- and low-temperature, stand-alone coolers and freezers commonly used in restaurants, convenience stores (C-stores) and small-format food retailers have been key targets of the Department of Energy’s (DOE) energy efficiency mandates. Because highly efficient compression technologies are among the few design options left to help OEMs meet these targets, Emerson is pleased to announce its Copeland variable speed reciprocating hermetic compressor line designed specifically for this purpose. For full details, you can read our latest E360 Product Spotlight.

While our industry expects that the DOE will soon be proposing its next phase-down in energy reductions for these applications — which are likely to take effect in 2024 — the need for highly reliable, energy-efficient compressors extends well beyond commercial refrigeration. In fact, OEMs in the environmental life sciences, medical and pharmaceutical industries can also benefit from the high efficiency and reliable performance of the Copeland variable speed reciprocating hermetic compressor line. In addition, many OEMs are also seeking a competitive edge by offering equipment that achieves ENERGY STAR® certification. The range of applications across these industries includes:

  • Medium- and low-temperature stand-alone refrigerators and freezers, including ultra-low temperature (ULT) freezers
  • Island cases
  • Display cases
  • Ice machines
  • Food prep tables
  • Medical equipment
  • Process chillers

Superior energy efficiency and refrigeration performance

Copeland variable speed reciprocating hermetic compressors are designed to deliver significant efficiency and performance improvements for commercial refrigeration reach-in OEMs. This low-profile, variable speed solution is comprised of two components:

  1. Copeland variable speed reciprocating hermetic compressor — available in ranges from ⅛ to ⅞ HP; featuring a brushless permanent magnet (BPM) motor vs. a standard induction motor
  2. Variable speed (VS) drive with a smart controller — includes serial, frequency and drop-in modes; drop-in mode serves as the system controller

Standalone, reach-in freezer optimized and tested with Emerson components and controls, under EPA-approved test lab for the ENERGY STAR® program per ASHRAE 72 and DOE energy testing requirements showed:

  • System efficiency increased by 13% by replacing fixed speed compressor with variable speed solution
  • Compressor cycling reduced by 90%
  • Compression ratio relaxed by as much as 43%
  • Manufacturer exceeds ENERGY STAR performance levels
  • Utilizes a future-oriented, low-GWP natural refrigerant

For end users of this enhanced refrigeration equipment, these efficiencies can result in:

  • Faster pull-downs to setpoint temperatures
  • More precise temperature holding
  • Less wear and tear on system components
  • Lower energy bills

In addition, the breadth of the Copeland variable speed reciprocating hermetic compressor line gives system design engineers a variety of compressor options with which to achieve significant energy efficiency improvements for refrigeration equipment of varying types and sizes.

The regulatory advantages of R-290

The Copeland variable speed reciprocating hermetic compressor line is designed to utilize R-290, a natural refrigerant, with an ultra-low global warming potential (GWP) of 3. This allows OEMs to offer their customers a refrigeration option that meets some of the most stringent refrigerant and energy efficiency regulations to date, such as:

  1. Potential impending DOE 2024 standard
  2. California Air Resources Board (CARB)
  3. Potential Environmental Protection Agency (EPA) refrigerant requirements
  4. ENERGY STAR® certification

Emerson’s test labs have confirmed that the use of R-290 in variable speed compressors can deliver superior annual energy efficiency ratio (EER) ratings compared to using R-404A in a fixed-speed compressor.

Helping OEMs meet DOE 2024 and beyond

The estimated timeline for the DOE’s next phase-down in commercial refrigeration equipment energy consumption is 2024. If current equipment does not meet DOE requirements, most OEMs will soon need to integrate new components into their next design cycle to comply with the next generation of energy reduction mandates.

The Copeland variable speed reciprocating hermetic compressor line delivers the energy efficiency levels that will help your equipment meet the upcoming DOE requirements — all while giving your customers the reliability and performance improvements they’ll need to succeed. With our extensive design and testing resources, Emerson can help to guide you through this transition. We’re ready to help you meet the next round of DOE efficiency standards and beyond — and achieve the ENERGY STAR® certification to differentiate you from your competitors.

[New E360 Webinar] Preparing for DOE Compliance on Walk-In Coolers and Freezers

Julie Havenar | Product Manager – Condensing Units
Emerson Commercial & Residential Solutions

In 2020, the Department of Energy (DOE) will begin enforcing its new energy-efficiency standards on walk-in coolers and freezers (WICF). With the compliance deadline now on the horizon, the commercial refrigeration supply chain is taking a closer look at the ruling and preparing for its impacts. Our next E360 Webinar, on Thursday, Sept. 26 at 2 p.m. EDT/11 a.m. PDT, will shed light on the details of this rulemaking.

Improving the energy efficiency of refrigeration equipment is a goal shared by most stakeholders in the commercial refrigeration supply chain. But when specific energy reductions are mandated by DOE regulations on a commonly used class of equipment, then these goals take on a much greater sense of urgency. The DOE’s 2020 WICF mandate is no exception.

Generally speaking, the ruling will require 20–40 percent energy reductions in WICFs smaller than 3,000 square feet. But, like many regulations of this kind, when you start digging into the details, you’ll find that they’re complicated and often difficult to interpret.

In our next E360 Webinar, I’ll provide a detailed overview of the DOE’s WICF ruling and discuss how it can impact you — regardless of whether you’re an equipment manufacturer, contractor, end user, design consultant or wholesaler. So, if you’re unsure about how to prepare for compliance or just curious how the ruling may impact you, then be sure to join me on Thursday, Sept. 26 at 2 p.m. EDT/11 a.m. PDT for this informative webinar. Attendees will learn:

  • The full scope of the WICF rulemaking
  • Definitions of key terms, concepts and language used
  • Final enforcement dates per equipment category
  • Examples of WICF system configurations
  • Required efficiency levels per the Annual Walk-in Efficiency Factor (AWEF) metric
  • Impacts to various stakeholders throughout the supply chain
  • How to verify and ensure compliance

As with all E360 Webinars, we will allocate time after the presentation for a question and answer session. To make sure we’re able to address your specific questions, this session will be supported by additional Emerson experts on the DOE WICF regulation, including: Roxanne Scott, senior lead project engineer; and Brian Buynacek, senior consultant. So, register now for this informative webinar and let us help you prepare for the DOE WICF compliance deadline.
