The GreenChill Advanced Refrigeration PartnershipGreenChill & Natural Refrigerants

U.S. Food Retail RefrigerationEnvironmental Impact35,000,000 lbs. of supermarket refrigerant emissions annually DX (direct expansion) systemsR-22 refrigerant (at least 50% of stores)High GWP substitute refrigerants (maybe 50% of stores)

Clean Air Act & Regulations to reduce supermarket refrigerant emissionsLeak repair trigger for equipment that leaks 35% of its charge annually

The GreenChill Advanced Refrigeration PartnershipVoluntary partnership program with food retailers to reduce their impact on the ozone layer and climate changeMeasure emissions set goals measure againStore Certification Program Promoting advanced refrigeration technology, strategies, practices

GreenChill ExpansionLaunched with 10 founding partners in Nov. 2007Less than 2 years later:46 partner companies6533 food retail stores 47 of 50 states (+DC)about $120 billion in sales

GreenChill Food Retail Partners

GreenChill Partner AchievementsGreenChills supermarket partners emit on average 12.3% of their charge (vs. 25% national average)If every supermarket in the nation reduced refrigerant emissions down to 12.3%...Potential greenhouse gas savings of 22,000,000 metric tons of CO2 equivalent PER YEARPotential to save 240 ODP tons PER YEAROver $108,000,000 industry savings PER YEAR

Recent Progress for Natural RefrigerantsCO2 use as primary refrigerant EPAs SNAP ProgramCO2 use as secondary refrigerantPropane use for stand alone commercial refrigeration equipment is going to be found acceptable by SNAP programNatural refrigerant protocol being implemented for GreenChill platinum level certificationSigns of increased interest over past few months

Other Factors Affecting AcceptanceUS proposal to phase down HFC use under Montreal ProtocolUS Greenhouse Gas Legislation is expectedPrice pressure due to R-22 phaseout?Isobutane use is going to be found acceptable for home refrigerators and freezers by SNAP program

General Challenges Need application to start SNAP processLack of svc. tech experience/trainingLack of dataFear of liability, esp. for NH3 & HCsPublicity about dangers, toxicity, flammabilityHigher costs of natural refrigerant systemsNo economies of scale yet, low volumeHigh prices for European equipmentNo manufacturer cross over among US manufacturers

General Challenges No drop-in retrofits available for existing systemsMultiple layers of complicated regulations-federal, state, local, building codes, permittingNo understanding among local officials about advantages and disadvantages of natural refrigerantsNo good guidelines for safe implementationPhilosophical debate: stop leaks or move to low GWP refrigerant?

General ChallengesReluctance to change satisfaction with chemical refrigerantsInexpensiveReadily availableLots of training by chemical companiesChemical systems are very forgiving and safe natural refrigeration systems require more care with system design, installation, servicing

Specific Challenges CO2No US manufacturer for transcritical systemsASHRAE has very specific language for design pressures US Guidelines are stringent & conservative; liabilityTrying to adapt it for cascade systemsTranscritical standards are a long way offNo Underwriters Laboratory approval yet Energy penalty esp. in warmer climatesHard to explain difference between good CO2 and bad CO2

Specific Challenges for Natural Refrigerants - hydrocarbons

Not yet SNAP approved for commercial refrigerationVery high charges would be needed flammability; liability

Specific Challenges for Natural Refrigerants - AmmoniaSNAP-approved for use as primary refrigerant in secondary loop commercial applications; no demandUse in industrial areas; supermarkets located in residential neighborhoodsMust have engineer on-site 24/7/365 & process safety management planDifficulties servicing equipmentLg. industrial plants can shut down facility for inspections/maintenanceNo service tech. cross over - different education, pay levelsDifferent end-user needsIndustrial systems - durable, expensive, long-termSupermarket systems remodeled every 10 years, short-term, cheap

*Commercial Refrigeration Systems used in a food retail setting can and do contribute to Ozone depletion and global warming.Do 1st section on info about supermarketsAERB agreed that there was a lot of potential for improvement within this industry. The existing regulations do not kick in until quite a lot has already been emitted, and enforcement is difficult and lower priority within Air Enforcement.At the same time that AERB was looking into this, the supermarket industry and trade associations started to think about the industrys environmental impact, and people in the industry started to realize that the emissions that cause harm also damage a supermarkets bottom line.

AERB felt that the willingness and desire was there on the part of the supermarket industry to change their environmental practices, so we created the GreenChill Advanced Refrigeration Partnership.

Through GreenChill EPA seeks to reduce refrigerant charges and emissions, which is good for the environment and good for your bottom line. We do this by promoting advanced refrigeration technologies, strategies, and practices. That means we promote distributed systems and secondary loop systems, but we are also in favor of advanced DX systems that reduce charges and emissions. We are in favor of good data management; we are in favor of leak alert systems; we are in favor of service tech training, we are in favor of CO2 systems. We are in favor of anything that reduces charges and emissions. Because thats what we need to do to repair the ozone layer and fight global warming.

GreenChill just had its 1st year anniversary on November 27th. We are quite happy with the accomplishments of the 1st year. The acceptance within the industry has been good. But the time really IS ripe, and what is holding us back from being even better is a personnel shortage. I have no problem recruiting people. Unfortunately there is no time to devote to doing that. It takes a one-on-one conversation (preferably in person) to educate a supermarket rep about the Partnership and point out the benefits of becoming a partner. It is more than a full time job to manage the existing partners and projects, and there is no one to get the word out or recruit. The partners who did come on board came to US, in response to a lot of articles in the trade press. (In addition to the 42 partners, I also fielded over 50 email requests from people who do not qualify to become partners, and probably twice as many phonecalls) The trade press is very interested and enthusiastic about GreenChill, but there is no time to capitalize on that either.

So in summary, we have reached the limit of what we (I) can do.

Id like to spend some time on GreenChills first year achievements.- The launch event was televised live over IPTV, and you can watch the entire event on our website. We gave out founding partner awards to our 10 founding partners. There were in total about 60 people there, incl. trade press. We got a lot of publicity and inquiries from potential partners came flooding in. as well as inquiries from the press.We did a podcast that people can download onto their MP3 players

GreenChills Store Certification Program.We set refrigerant charge reduction goals and leak tightness goals, and any store that achieves these goals receives GreenChill gold or silver award for advanced refrigeration.We decided to develop this Program because the LEED Retail certification system did not give enough credit to refrigerant management, even though refrigerants are the sole responsible activity for the industrys effect on the ozone layer, and they make up 1/3 of a stores carbon footprint, 2nd only to electricity use, half of which is the refrigeration system.Not giving proper credit for stores that are taking the lead in refrigerant management is perhaps encouraging stores to invest in environmental improvements that do not have as much impact on the environment as refrigerants.So we decided to solve that problem.

We realized that a lot of stores were retrofitting their R-22 systems to use HFC chemicals in preparation for the price increases they anticipate with the upcoming R-22 phaseout. We wanted to stress the importance of making sure when you retrofit that you also tighten up the leaks in your system its not just a question of sucking out the R-22 and replacing it with an HFC otherwise you are just again leaking an HFC instead of R-22. This Guideline is a very rich document, with everything anyone involved in retrofits needs to know from executives making decisions on whether to retrofit to purchasers deciding on a chemical to the svc. tech carrying out the retrofit. Ive been told that this Guideline has led to companies re-thinking their retrofit policies and retraining their maintenance people to follow the guidelines.

Our installation leak tightness guidelines were developed because we thought that you cant be serious about leaks if you arent even making sure that a new system is being installed to be guaranteed to be leak tight at installation. And if a system is leak tight at installation, chances are that it will remain leak tight for a long time. There was a huge range of practices to supposedly ensure that a newly installed system is leak tight, at least to start. We developed a step-by-step manual on how to test your system to make sure that it is leak tight. This document is enormously popular with the industry. Even Wegmans, which is not a partner, has taken the guideline and adopted it as their technicians specs for installation. A lot of companies did not have one standard procedure it was left up to the contractor.
