Emerson’s new CO2 Booster training unit is preparing to make several stops across the U.S. and Canada in 2019. Learn more about what this hands-on experience will offer attendees.

Adoption of the natural refrigerant CO2 (R-744) in commercial and industrial refrigeration applications is on the rise in North America and around the globe. With 0 ozone depletion potential (ODP) and a global warming potential (GWP) of 1, CO2 is considered the environmental standard by which other refrigerants are measured. But with its high operating pressures and unique performance characteristics, industry stakeholders have many questions about how to design, operate and service a CO2 system. That’s why Emerson is pleased to introduce its new, mobile CO2 Booster training unit.

The CO2 training unit is designed to give contractors, manufacturers, wholesalers and end users a hands-on experience and learn what it’s like to work on a CO2 refrigeration system. Launched in Canada in September, the unit has already visited locations in Quebec and trained more than 50 contractors. In early 2019, the unit will travel to the U.S. and make several stops, starting with an appearance in the Atlanta area timed to correspond with the conclusion of the AHR Expo. The current schedule is as follows:

  • January 16–17: Atlanta, Ga.
  • January 30–31: Orlando, Fla.
  • February 13–14: Rancho Cordova, Calif.
  • February 27–28: Elmsford, N.Y.
  • March 20–21: Cudahy, Wis.
  • April 10–11: Brantford, Ont.

Each stop will feature a two-day training session designed to accommodate 20 attendees and cover a wide range of CO2-related topics, including:

  • Subcritical vs. transcritical modes of operation
  • Overview of CO2 system architectures
  • Safe handling, maintenance and charging
  • Startup and shutdown sequences

Become familiar with CO2 and refrigeration system components

The open 360° view of the training unit allows attendees to familiarize themselves with the refrigerant and the components which make up a CO2 system. To demonstrate the volatility of CO2, the unit includes a phase change cell that shows how the refrigerant reacts to pressure changes. Starting in its liquid state, R-744 is subject to increasing pressures and begins its transition into a vapor state, then to a supercritical fluid, until it ultimately becomes a transparent gas. Then, as pressure is dropped within the cell, attendees can see the reverse of this transition as CO2 returns to a liquid state and then forms into a solid piece of dry ice.

The CO2 Booster training unit utilizes a full Emerson system that includes: low- and medium-temperature compressors, electronic controls, protectors, variable-frequency drives and transcritically rated electronic expansion valves. For ease of use, the unit is designed to improve the visibility of all components and dial gauges to demonstrate pressures and temperatures of certain elements.

The transportation container is designed for simplified transport and protection against the rigors of over-the-road travel. This container is also equipped with Emerson’s Cargo Solutions that allow live tracking of the unit’s location, ambient temperature and other conditions through Emerson’s Oversight app.

Registration for scheduled two day sessions is now open. The cost is $700 per person and includes all course materials, breakfast and lunch.

Join us our next E360 Webinar, “The Risks and Rewards of Connecting Commercial Kitchens” on Tuesday, December 11 at 2 p.m. EST / 11 a.m. PST.

The Risks and Rewards of Connecting Commercial Kitchens

It seems everywhere you turn and across multiple industries, companies are touting the promise that the internet of Things (IoT) will digitally transform their operations. The restaurant sector is no exception. In recent years, original equipment manufacturers (OEMs) and restaurant retailers have spent considerable time and effort figuring out how to leverage the power of connectivity in commercial kitchens.

While it’s relatively easy to conceptualize how the internet of things (IoT) could improve operational efficiencies and provide business value, bringing these ideas to fruition has proved more difficult. Too often, we see retailers make the jump to connecting assets without first having a clear idea of what problem they’re trying to solve, or how connectivity will fundamentally change the way their business operates. Then, once everything is connected, they’re left wondering: “What’s next?”

Our next E360 Webinar will examine why this is the case, and focus on how foodservice OEMs and retailers can work together to tap the seemingly limitless potential of IoT. My presentation, “The Risks and Rewards of Connecting Commercial Kitchens” will focus on these key points:

  • The importance of defining the scope and purpose of your connected project
  • An examination of the far-reaching and dramatic impacts to your business
  • Real-world examples of successful and failed connectivity projects
  • Evaluating business models that involve service contracts, recurring revenue or monetization

Another common problem with connected kitchen projects is underestimating the complexities inherent with these new business models. For example, a connected maintenance offering might require somewhat sophisticated coordination of not only OEM and end user roles, but also the inclusion of an authorized service provider. Frankly, these are the types of business relationships and interactions that are often overlooked when companies rush to exploit the power of IoT before thinking through the implications.

The webinar will look at these challenges from both OEM and retail perspectives. For an OEM, it’s critically important to understand their customers’ business needs before launching a connected initiative. Similarly, retailers need to realize that without involving and engaging their OEM partners in their connected kitchen strategy, they’re not likely to achieve the maximum potential of their IoT solution.

So, if you’re thinking about entering into a connected kitchen project or IoT business model in the restaurant sector, register now to gain a better understanding of the risks and rewards of connectivity.

How to Create the Perfect Climate in Supermarkets

I recently participated in an article for Winsight Grocery Business, which discussed the importance of keeping refrigeration and HVAC systems in harmony. Click here to read the full article.

How to Create the Perfect Climate in Supermarkets

Refrigeration and HVAC costs are among the biggest operational expenses a supermarket faces. The reasons? People create warmth. Refrigeration creates cold. Humidity creates wetness. And in supermarkets, HVAC systems constantly struggle to maintain the right temperature and humidity for people, equipment and products. With proper management and planning, supermarket operators can balance these factors and even optimize HVAC and refrigeration systems to work in coordination with each other.

 The battle between HVAC and refrigeration

In most buildings, the job of an HVAC system is to maintain a comfortable indoor temperature for customers and staff. But HVAC systems face unique challenges in supermarkets. Coolers, refrigerated display cases, freezers and other units (particularly those without doors), pour cool, dry air into stores. This isolated cold air stresses HVAC systems year-round, as they have to increase heating during winter — burning a lot of energy — while leaving uncomfortably cold spots, even in summer. Your refrigeration equipment alters an HVAC load in ways most systems aren’t designed to handle.

Adding doors or replacing open units can reduce both the load and energy costs. But adding doors creates a different problem: they often fog up — which forces shoppers to open the doors to see what’s inside — defeating the whole purpose of having a door. Fog and frost occur when humid weather, steamy shoppers and chilly air collide.

A foggy situation

Door fogging is a symptom of a very tricky problem: keeping in-store relative humidity (RH) at the proper percentage. If humidity is too high, doors fog over and cooling coils frost up, forcing units to overwork. If the humidity gets even higher, water can condense on floors, walls and even dry-goods packaging. But if the RH is too low, the overly dry air can shorten the shelf life of fresh produce or wilt it.

Moisture, relatively

Almost all the humidity inside a store comes from moister outside air, and it’s up to HVAC systems to lower that humidity to a slightly dry 45 percent RH — and that’s not easy.

The simplest way to do this is to super-chill incoming outside air, because as air cools, its humidity drops. But this wastes energy in two ways: it increases the refrigeration load on the HVAC and can chill the entire store. So, the air first has to be reheated before entering the store, producing yet another energy expense.

Another option to use a desiccant system in the HVAC unit to remove moisture. These systems are effective and reliable, but they require a lot of energy, especially for large spaces like supermarkets.

Harvest-free heat

The article describes a simpler, cheaper solution. The compressors on your refrigeration equipment generate a lot of heat as they compress refrigerants. This excessive heat is usually vented outside the building, wasting a source of free heat. Today, systems can recycle, treat and mix this hot air to create ideal store temperatures and RH — at much lower overall costs.

Advanced systems harvest excess hot air in various ways. Some use the hot vented air instead of the HVAC heater to reheat super-cooled, dehumidified air and reduce reheating costs. Some systems use heat exchangers to recycle the vented hot air to heat a supermarket during cold weather. “Single-path” systems super-chill a limited volume of humid outside air to dry it, then mix it with uncooled air to produce just the right temperature/RH mix. Another system uses two cooling coils, one to cool the hot air as it’s being vented outside, so it can mix with outside air to reach optimal temperature and RH. The incoming air needs little heating or cooling as it reaches the second coil, which greatly reduces the workload on the HVAC system.

Instead of adding to your HVAC system’s workload, your refrigeration equipment can actually help reduce the load, lower your costs, and create the ideal climate for shoppers, employees and facility managers.
