  • La sicurezza ambientale Tutto è nato nel 1997 quando alcuni scienziati radunati nel pannello intergovernativo sui cambiamenti climatici IPCC hanno verificato che l'attività umana poteva essere causa del surriscaldamento terrestre e dei disastri ambientali che sono andati incrementandosi negli anni.
    La temperatura media del globo terrestre aumenta, è già aumentata di circa 1 ° nell’ultimo secolo.
    Nel 2007 l’ultimo rapporto del IPCC stabilisce che non è più una probabilità ma è una certezza che è l’uomo la causa del surriscaldamento terrestre. Ciò prvoca terremoti in aumento, alluvioni, tempeste e altre calamità naturali direttamente imputabili al surriscaldamento terrestre. L'anidride carbonica è stata in continuo aumento dalla rivoluzione industriale ad oggi..
    Nasce così in quell’anno il protocollo di Kyoto.
  • Revision of the F-Gas Regulationpossible measures:
    Possible measures
    HFC phase down: similar to North American proposal
    Ban on HFCs of GWP > 2150 from 2018 for servicing & maintenance
    Bans on HFCs in new refrigeration & freezing equipment
    Inclusion of refrigerated road transport
    Training & certification on alternatives to HFCs
    Ban on pre-charging of non-monobloc a/c equipment: charging must be done on-site by a certified installer
    Suppliers cannot sell HFCs to non-certified installers
    Definitions of “recovery”, “reclamation” and “recycling” are aligned with those of the ODS Regulation

  • Normally higher is the GWP less flammable are the refrigerants on the right of the graph
    With the exception of CO2 which is no flammable and has a GWP=1 for definition.
    You can see that R32 has a higher capacity than R22 and R410a
    HFOs are still HFCs and they have a very low GWP as they have a very short life
    before they disgragate, they do not have the time to arrive to the
    atmosphere level to be dangerous. (11-18 days life)
  • A2L refrigerants are so mainly the new HFOs – R32 (1)
    Pro
    Nearly drop-in
    Low changes for the manufacturers, the contractors and the end-users
    Good/High performances
    Low Toxicity
    Nearly same tools-equipments
  • HFOs – R32 (2)
    Not yet widely used (even if R32 is a old known refrigerant but rarely used as single, component of R410a)
    HFOs not commercially available – few factories (mainly in US) high costs for high demand low offer (over 100 €/kg at the moment?). Mainly automotive.
    Mildly flammable
  • What means mildly flammable
    LFL lower flammability limit, the lower volume of hydrocarbons needed to get fired, 6.2 for HFO, none for HFO1234ze below 30°C
    Comparison with propane
    both R32 and HFO has lower risky figures.
    We need more concetration of substance to occur a flame,
    The flame velocity is very slow
    High energy necessary for the ignition
    Is it managable?
    What is the limit managable and not managable?
  • AREA position on training and certification of LOW GWP refrigerants (1)
    So for the future phase-down of HFCs will lead to a higher use of alternative refrigerants / low GWP refrigerants. Low GWP refrigerants have issues on safety, flammability, toxicity and high pressure which will need to be properly considered when handling those refrigerants. With this guidance document, AREA would like to recommend to worldwide and European decision-makers minimum requirements for training and certification of contractors handling low GWP refrigerants.
  • It is not AREA’s intention to create a new certification scheme – only to add specific modules to the existing HFCs certification scheme based on Regulation 303/2008. While HFC certification will be the basis for every contractor who want to handle every refrigerant, each added module will focus on the specificities of the respective LOW GWP refrigerant (i.e. Hydrocarbons – Flammability).
    Training is important and it is the only method to transfer to the contractor the knowledge to install, maintain and repair RACHP systems containing alternative refrigerants considering both the technical and safety issues.
    For the training facilities AREA suggests that test rigs, equipment and components related to each alternative refrigerant are recommended to simulate best practices
    AREA suggests that certification should be made mandatory.
    Each candidate who wants to handle alternative refrigerants should hold a certificate which assessed to the requirements of 303/08 and should take part in an assessment specifically for the alternative refrigerant he wants to handle.
  • In the same way AREA Task force released here for ChillVenta this new position paper about:
    Guidance on minimum requirements for contractors’ training & certification
    The table below lists the minimum competences which the candidate should have to obtain the certification specific to each alternative refrigerant
    *HFO1234yf: same, minimum requirements as Hydrocarbons HC
    *HFO1234ze: same minimum requirements as HFCs
    R32 as Hydrocarbons HC
    Procedures for working with A2 and A2L (proposed) refrigerants have not yet been formulated, so the procedures for A3 refrigerants (HCs) should be followed until these are available.
    BASIC THERMODYNAMICS AND PHYSICS
    Thermodynamic properties of Low GWP refrigerant: temperature, pressure, density, thermal capacity, p/h diagram
    Differences between Low GWP refrigerants and HFCs
    Toxicity characteristics, grades and limits for the human body
    Characteristic of Flammability of the substances, velocity of propagation, LFL, UFL, occupancy
    Specific components for that refrigerant in the refrigeration cycle
    Material compatibility
    Oil compatibility, requirements and oil return
  • GOOD PRACTICE
    Identify typical application of Low GWP refrigerants RAC systems2 (refer to AREA: Low GWP Refrigerants Guidance)
    State and identify the commonly used refrigerants designation
    State the requirements for safely labeling Low GWP refrigerant RAC systems6
    Select appropriate tools, equipment and PPE for work on Low GWP RAC systems6
    Recovery of the refrigerant
    Venting the refrigerant in a safe way (according to national legislation)
    Calculate the safe fill weight for the recovery cylinder (density difference between HFCs and Low GWP refrigerants) 2
    Leak check direct assessment with the correct equipment
    Make vacuum of the refrigerant preventing moisture in the system and without refrigerant emissions
    Make charge of the refrigerant with no emission relief
    Make a connection without brazing with alternative connections
    Check the correct functioning of the safety ventilation system
    Check the correct functioning of the safety system controls
  • HEALTH AND SAFETY REQUIREMENTS
    Safe system shutdown and isolation 2
    Extinguish a fire, identify the appropriate fire extinguisher
    First aid care treatment for frostbite
    First aid due to fire burn
    First aid suffocation due to breathing problems
    Safety issues related to high pressures
    Calculate LFL (confined space)
    Calculate confined space for asphyxiation (heavier than air)
    Check that Health and Safety rules in the refrigeration system location are respected (emergency exits, fire alarms, leak detectors…)
    Correct use of Personal Protective Equipment
  • REGULATIONS AND STANDARDS
    Knowledge of European and National Regulations and standards
    Storage of the refrigerant
    Transport of the refrigerant
    Describe the process for handing over system to costumer completing and passing on appropriate commissioning documentation2
  • Equipment (1)(few available on the market)
    Characteristic: Flammable proof
    Leak detector
    Recovery unit
    Charging station (automotive)
  • If an electronic leak detector is used it must be safe and sensitive to the flammable refrigerant. Most HFC leak detectors do not need this requirement. Leak detection fluid can be used.
    HFC recovery machines have not been assessed for use with flammable refrigerants. Approval must be sought from the manufacturer before using a standard HFC recovery machine with any flammable refrigerant – they may be safe to use with flammable HFCs but not HCs. A recovery machine suitable for use with HCs is available and could be used with other flammable refrigerants.
    fire extinguisher must be available at the location
    ventilation fan should be used when working inside

    5. 5. The Environment Source UNEP United Nations Environment Programme Currently, global temperature is around 0.8 degrees Celsius higher than in the pre- industrial era. Without climate policy, this increase will rise to around 2 degrees by 2050, and to between 2.5 and 6 degrees by the end of this century. They have been rising ever since, and today are about 394 ppm. A level of 450 ppm has generally been associated with an average global temperature rise of 2 degrees C
    6. 6. Europe: The current political context The EU 20 – 20 – 20 target To stay below 2°C every country will have to reduce its greenhouse gas emissions (GHGs), but developed countries will need to take the lead by targeting a cut of 80- 95% below 1990 levels by 2050.(1) (1) EU Commission Climate Action - FAQ

    13. 13. Technology and knowledge Training, Assessment (1) Strengthening national refrigeration & air- conditioning (RAC) associations in Eastern European & Central Asian countries 27 November 2012 – Casale Monferrato: The Italian Centro Studi Galileo, the European Association of Refrigeration, Air-conditioning and Heat Pump Contractors (AREA) and the United Nations Environment Programme (UNEP) joined forces to strengthen national refrigeration & air- conditioning (RAC) associations in Eastern European and Central Asian countries.
    14. 14. Technology and knowledge Training, Assessment (2) Representatives of national RAC associations participate since 2009 in the meetings of the Regional Ozone Network for Europe & Central Asia (ECA network) and they play a crucial role in implementing the national HCFC phase-out management plan. The meeting focused on those countries with relatively young RAC associations and those which are planning to establish such associations in the near future. So far, the ECA network supported the creation of national RAC associations in Bosnia & Herzegovina, Croatia, and Macedonia FYR. All participants successfully passed the theoretical and practical assessment and were certified under the F-gas regulation. This certification is mandatory in the member countries of the European Union and will shortly become mandatory in accession countries like Croatia.
    15. 15. Conclusions of EU commission Public consultation In the context of the overall EU objective to cut emissions by 80–95 % by 2050, the stabilisation of F-gas emissions at today’s levels is not adequate and the analysis shows that already available or emerging low-GWP technologies are technically feasible and can be cost effective in many application areas
    16. 16. The agreed regulation will allow to reduce F-gas emissions by two-thirds of today's levels by 2030. The use of F-gases in some new equipment, such as refrigerators and air conditioners, will be banned where viable and more climate-friendly alternatives are readily available. The new regulation will not only benefit the climate, but also create great business opportunities for EU companies on the market for alternative technologies. It establishes rules regarding containment, use, recovery and destruction of those gases. In addition, the new law imposes conditions on the placing on the market of products and equipment containing or relying upon F-gases, whilst setting out quantitative limits for the placing on the market of hydrofluorocarbons (HFC). The regulation also introduces bans on the placing on the market of the following products: – domestic refrigerators and freezers containing HFCs with a global warming potential (GWP) of 150 or more as from 1 January 2015; – refrigerators and freezers for commercial use containing HFCs with a GWP of 2500 or more from 1 January 2020, and containing HFCs with a GWP of 150 or more from 1 January 2022; – stationary refrigeration equipment that contains or relies upon for its functioning HFCs with a GWP of 2500 or more from 1 January 2020; – centralised refrigeration systems for commercial use with a capacity of 40kW or more that contain or rely upon their functioning, fluorinated gases with a GWP of 150 or more, from 1 January 2022; Revision of the F-Gas Regulation (1)
    17. 17. – movable room air-conditioning appliances that contain HFCs with GWP of 150 or more from 1 January 2020; – single split air-conditioning systems containing less than 3 kg of F-gases that contain F-gases with a GWP of 750 or more from 1 January 2025; – foams that contain HFCs with a GWP of 150 or more, extruded polystyrene from 1 January 2020 and other foams 1 January 2023; and – technical aerosols that contain HFCs with a GWP of 150 or more from 1 January 2018. (1) The first ban is the much-touted service and maintenance ban on high-GWP refrigerants, over 2500 GWP, which is planned to come in 2020 (2) The Regulation will apply from 1 January 2015.

    18. 18. Contractors’ training with low GWP refrigerants: mind the gap! If the use of HFCs is legislatively decreased and consequently the use of natural refrigerants is pushed, there will be a gap between training offer and training needs resulting in a shortage of trained contractors The European Commission is working on a revision of the F-Gas Regulation that could include measures in favour of a decreased use of HFCs in RACHP equipment. Such measures would, in turn, result in an increased use of alternatives, namely low GWP (global warming potential) refrigerants, and in particular the so-called “natural refrigerants” (CO2, hydrocarbons and ammonia). Mindful of the key role played by contractors in the safe, efficient and reliable functioning of equipment working with natural refrigerants, AREA sought an overview of the availability and level of training in the EU. Solution could be starting from the F-Gas certification of personnel adding modules for natural refrigerants
