Refrigeration - Key Legislation & Regulations • Prevent leakage, and repair any leaks as soon as possible • Arrange proper refrigerant recovery by certified personnel during • servicing and disposal • Carry out leak checks to the schedule shown below • Ensure that only certified competent personnel carry out leakage • checks • Maintain records of refrigerants and of servicing Fluorinated Greenhouse Gas Regulations 2009
Refrigeration - Key Legislation & Regulations EU Regulation (EC) No 842/2006 On Certain Fluorinated Greenhouse Gases UPDATE ANNOUNCED 7TH NOVEMBER 2012 Key Proposal A phase-down measure that from 2015 will limit the total amount of HFCs that can be sold in the EU and reduces this in steps to 1/5th of today’s sales by 2030.
Refrigeration - Key Legislation & Regulations UPDATE 7/11/12 EU Regulation (EC) No 842/2006 On Certain Fluorinated Greenhouse Gases
Refrigeration - Key Legislation & Regulations UPDATE 7/11/12 EU Regulation (EC) No 842/2006 On Certain Fluorinated Greenhouse Gases Recharging of existing refrigeration equipment with a charge size over 5 tonnes ofCO2 equivalent with HFC of very high GWP (>2500) will not be permitted from 2020 onwards……… …………as more adequate and energy efficient drop-in refrigerants of lower GWP are already widely available on the market. Note: For R404A, 5 tonnes of CO2 equivalent is a system charge of 1.32kg.
Refrigerants Status Bitzer Refrigerants Report 16 ? ?
The Perfect Refrigerant • Chemically stable and inert • Suitable for cooling applications from -75OC to +20OC • Good thermodynamic characteristics • Non-toxic • Non-flammable • Zero ozone depletion potential (ODP) • Low global warming potential (GWP) • Low cost • Available
The Perfect Refrigerant Ammonia (R717)? Among the earliest of refrigerants, its positive attributes include: • Chemically stable and inert • Wide operating range • Excellent thermodynamic properties • Zero ODP • Zero direct GWP • Low cost: refrigerant and oils • Good safety record
The Perfect Refrigerant Ammonia (R717)? Its challenging attributes include: • Toxic • Flammable at certain concentrations in air (15% to 28% • by vol.) • Not compatible with copper or copper alloys • High discharge temperatures - limiting single stage • operation, particularly with reciprocating compressors • Non-miscible with lubricating oils • Poor public perception
The Perfect Refrigerant Carbon Dioxide (R744)? An early refrigerant which has seen a renaissance in applications over the past 10 years, Carbon Dioxide’s positive attributes include: • Non-toxic • Non-flammable • Positive pressures across complete operating range • High efficiency at low temperature • Cheap refrigerant
The Perfect Refrigerant Carbon Dioxide (R744)? Carbon Dioxide’s positive attributes provide the following potential benefits: • Significantly enhanced performance • Smaller & fewer components, ie compressors, heat • exchangers & pipework • Potential for lower cost installation • Potential for lower cost operation • No recovery and “safe” disposal problems
The Perfect Refrigerant Carbon Dioxide (R744)? Carbon Dioxide’s challenging attributes include: • Relatively high operating pressures Sat Temp (oC) Pressure (bar(g)) R744 -45 7.32 R717 -45 -0.46 R404A -45 0.05 R744 0 33.85 R717 0 3.28 R404A 0 5.03
The Perfect Refrigerant Carbon Dioxide (R744)? Carbon Dioxide’s challenging attributes include: • Relatively high operating pressures • Low critical temperature R744 31oC R717 133oC R404A 73oC
The Perfect Refrigerant Carbon Dioxide (R744)? Carbon Dioxide’s challenging attributes include: • Relatively high operating pressures • Low critical temperature • Affects breathing reflex at concentrations > 2% Similar issues affect synthetic refrigerants, eg HFCs & HCFCs
The Perfect Refrigerant Does not presently exist! The application of all refrigerant options – and associated refrigeration system designs – is a compromise, each carrying its benefits and challenges Regulations, Standards & Guidelines provide the framework for ensuring the safe and appropriate application of all refrigerants
One Size – does not – Fit All The decision on which direction to take will depend on a range of criteria and the relative weighting given to each by those making the assessment. One size - does not - fit all.
