Refrigerant and Minimum Energy Efficiency

Regulations Require Industry to Balance the Equation

• Reduce energy consumption with

optimized refrigeration equipment

system performance.

• Ensure EPA compliance and reduce GWP

with refrigerant choices that minimize

impact to equipment performance.

• Preserve reliability, serviceability and

safety. Understand the toxicity,

flammability and pressure implications.

• Estimate the total cost of ownership

and viability of technology changes.

EC Motors

– EC (electrically commutated) motors are required by the Federal Energy Independence and Security Act of 2009 for new walk-in coolers less than 3,000 sq. ft.

– They are more energy efficient andrun cooler than other motors, introducing less heat into the refrigerated space.

– Energy efficient compared to othermotors on the market today.– Shaded Pole 25 – 35 % Efficient

– PSC 40 – 50 % Efficient

– EC 65 – 75 % Efficient

Variable Speed EC Motors

• Reduces Operating Costs

– Reduces fan motor power consumption

• 50% fan speed at 12.5% power

– Improves compressor and fan motor

durability

• Maintains Product Integrity

– More stable head pressure

– More stable liquid temperature

Total System Visibility and ControlChange Settings at the Touch of a Button

• Customers and restaurant operators value continuous,

real-time feedback loop

• Quick, efficient ways to reach busy foodservice operators

• Remote Monitoring is a fast-growing trend among aftermarket

providers and refrigeration system manufacturers

– Devices gather real-time system data

– Displays gathered data on the device

and/or over the Web

• Advanced form of troubleshooting, resulting

in first visit resolution

• Total system snapshot in one location

– Game changer is control of the system

• Easy-to-use interfaces

• Operators can change system set-points

at device or over the Web

Valuable System DataRun an Efficient Operation

• Manage multiple locations

• Compare system performance

• Download custom graphs

• Historical system data

• View real-time system statistics

• Remotely diagnose problems

• Increase first visit resolution

• Control system set-points

• Make changes from any Web browser

• Optimize your system

Squeeze Out Every InchAre You Optimizing Space in Your Walk-In?

• Time-starved consumers value quick shopping

and dining experiences

– “Express” or “city” small-store formats on the rise

• Small-format food retail on the rise, especially

in urban environments (Denny’s Fresh Express)

– ~2,000 sq ft. (⅓–½ normal size)

– Limited menu options decrease consumer

time/choices in store

• As concept expands, main goals are

maximizing space and efficiency

– Refrigeration systems and walk-in

coolers critical to maximizing space

• How can you help your clients?

– Space-saving evaporator solutions

– Packaged systems (top or side mount)
