f R-22 is primary refrigerant

f Harms the ozone layer (ODP of .055)

f Contributes to climate change (GWP of 1810)f Phase-out in 2010 of R-22 production for new

equipment; Limited production allowed until 2020 toservice existing refrigeration equipment

f DX systems are the dominant technologyf Lg. refrigerant charges (ave. spmkt. = 4000 lbs.)

f High leak rates (ave. 20-25% = about 1000 lbs. ofrefrigerant emitted PER SUPERMARKET per year)

Supermarket Refrigeration & theEnvironment


4/37

GreenChills Purpose

f EPA cooperative alliance with the supermarketindustry

f

Promotes the adoption of advancedrefrigeration technologies, strategies, andpractices

f Reduce charges & emissions of ozone-

depleting substances (potent greenhousegases)

f Help protect the ozone layer and protectagainst global warming


5/37

Why Adv. Refrigeration Tech.?

f Montreal Protocols goal is ozone layerrecovery reduces ozone-depletingsubstances (CFCs & HCFCs)

f Substitute refrigerants (HFCs) are ozone-safe, but they are greenhouse gases

f Leaking 1000 pounds of greenhouse gas

instead of 1000 pounds of ozone-depletinggas is just substituting one environmentalproblem for another


6/37

Benefits of Joining GreenChillf Benchmarking to evaluate progress

f Recognition for actions beyond regulatoryrequirements

f

Build brand equityf Tools to attain corporate environmental stewardship

and sustainability goals

f Prepare for HCFC phaseout and other deadlines

f Access to latest information on state-of-the-artrefrigeration technologies, alternative refrigerants,and best practices

f Networking & information sharing among partners


7/37

f Commit to using only non-ozone-depletingrefrigerants in both newly constructed stores andmajor remodels

f

Report a baseline of corporate-wide refrigerantstocks and emissions

f Commit to an annual emissions reduction goal

f Develop a corporate Refrigerant Management Planand emissions reduction strategy

f Report annual aggregate corporate-wide refrigerantstock and emissions
