1 Establishing and implementing the certification scheme the development process, the enforcement, registration/certification and monitoring mechanisms, training Component DUBAI, 2nd November 2015 Marco Buoni Director Centro Studi Galileo ( VicePresident, AREA Air Conditioning & Refrigeration European contractors Association ( Secretary General Italian Association of Refrigeration Technician, ATF (

2 Certification is the best practical method to verify the competence of personnel handling refrigerants and to ensure the correct installation, maintenance, repair and dismantling of a refrigeration, airconditioning and heat pump systems.

3 In Pills: To prevent refrigerant emissions Training and certification The Refrigeration, Air Conditioning and Heat Pumps systems containing fluorinated refrigerants in EU should have: - Logbook - Periodical inspections - Installation, repair only by certified craftsmen Refrigerant to be sold by distributors only to certified craftsmen Refrigerant to be withdraw only by certified craftsmen

4 Why creating Training, Assessment, Certification Certification is an important tool and a must to organize the labor market according to the national qualification classification system Through legislation, this will have the effect of: Reducing Refrigerant Emissions, GHG, ODS Increasing energy efficiency (reducing CO2) Contractor-driven: More aggressive competition requires proof of higher quality and certification Customer-driven: Wholesalers, distributors, big customers require environmentally friendly and energy efficient products Protects the interests of customer through providing services according to applicable standards Certification of the personnel and of the companies who handle air conditioning, refrigeration and heat pumps equipment

5 How to create Training, Assessment, Certification Recommended general structure National Authority Certifying bodies Advisory Committee of Eperts The National Authority is the governmental institution, for instance a Ministry or a National Agency, responsible for controlling the implementation of the overall certification scheme. The scheme includes a Certifying Body or Certifying Bodies carrying out the functions of assessment and certification / registration of personnel and companies working procedures and structure: the National Authority has to recognise the competence of such a Body or such Bodies in accordance with standards ISO The Certification Bodies must have eperience within the refrigeration sector and employ subject competent specialists in refrigeration and air conditioning. The Advisory Committee of Eperts assists the National Authority in its controlling mission and serves as a counsellor to define and update when needed the criteria for certification (e.g. demands and terms of assessment, structures and terms of inspections, ). The members of the Advisory Committee are eperienced representatives of the government, refrigeration vocational education bodies / schools, certifying bodies and relevant trade associations (industry and end users).

6 Who needs to be certified? (1 - Personnel) Natural persons (personnel) carrying out certain tasks on certain types of equipment must be certified or qualified. Equipment Stationary refrigeration, air conditioning, heat pump and fire protection equipment Refrigerated trucks (above 3.5 t) and trailers Air conditioning equipment in road vehicles Tasks a) Installation, servicing, maintenance b) Repair c) Decommissioning d) Leakage checking e) Recovery

7 (b) proof that the necessary tools and procedures are available to the personnel engaged in activities for which certification is required. Who needs to be certified? (2 - Companies) *some countries worldwide offer the certification of companies. It is likely that developing countries could use a different method to ensure the compliance of the requirements described below, for eample provided that the single service installer, as self-employed person, provides the compliance Companies carrying out certain tasks on certain types of equipment for other parties must be certified. Equipment Stationary refrigeration, air conditioning, heat pump and fire protection equipment Tasks Installation, servicing, maintenance Repair Decommissioning Companies should fulfils the following requirements (a) employment of personnel certified in accordance with Article 5, for the activities requiring certification, in a sufficient number to cover the epected volume of activities;

8 Equipment and tools Who needs to be certified? (2 - Companies) (2) Equipment and tools of the certified personnel to be supplied by his employer Manifold Vacuum Gauge or Vacuum Meter Temperature meter Portable leak detector Refrigerant weight Scale Vacuum pump Recovery set Nitrogen pressure regulator Recycling cylinder RC Figure 4 Recovery cylinder, how to label it Figure 7 Leak detector Figure 5 Vacuum pump Figure 8 Scale Figure 9 Vacuum Gauge Figure 6 Refrigerant recovery machine Figure 10 Pressure Manifold Figure 11 Temperature Meter

9 REGULATION (EC) 303/2008 (or EN becoming ISO) MINIMUM COMPETENCE OF PERSONNEL T = THEORETICAL P = PRACTICAL CATEGORIES DUTIES AND KNOWLEDGE I II III IV 1 Basic thermodynamics T T T 2 Environmental impact of refrigerants and corresponding environmental regulations T T T T 3 Checks before putting in operation, after a long period of non-use, after maintenance or repair intervention, or during operation P P 4 Checks for leakage T/P T/P T/P 5 6 Environment-friendly handling of the system and refrigerant during installation, maintenance, servicing or recovery Component: installation, putting into operation and maintenance of reciprocating, screw and scroll compressors, single and two-stage P P P P P 7 8 Component: installation, putting into operation and maintenance of air cooled and water cooled condensers Component: installation, putting into operation and maintenance of air cooled and water cooled evaporators P P 9 Component: installation, putting into operation and servicing of Thermostatic Epansion Valves (TEV) and other components P 10 Piping: building a leak tight piping system in a refrigeration installation P P

10 Assessment: practical organization issues Maimum candidates per class dependent on number of assessors Assessor/s should be independent and not involved in the training of the candidates Multiple answers tests, 30 questions for 90 minutes duration The same test among candidates with variation of questions to prevent predictability among candidates Closed books, only specific technical tools such as calculator and pressure-temperature comparator allowed NO! mobile phones or cameras NO! copying or communication between candidates YES! speaking to the assessor to ask eplanation of the modalities and of the questions if not understood; many candidates use different words and vocabulary to identify the same concept (eg. Valves) Theoretical assessment: Pass mark above 60% correct answers Laboratory is properly equipped for performing the practical test Practical assessment: Pass if candidate proves competence in performing main RAC service technicians activities without or with only small hesitations (remember candidates could be knowledgeable but be nervous!): Thermodynamic parameters reading through gauges and devices, temperature, pressure, subcooling, superheating Parameters interpretation, troubleshooting Perform a leak test Vacuum, charge, recovery with minimum emissions System Logbook reading, understanding and competition Brazing leak tight joints

11 Monitoring the results of the certification Monitoring systems consists of putting in place several tools within the National Certification Scheme: A register of certified personnel and companies publically available online (recommended) or held by a national authority Only certified personnel and companies can purchase refrigerants and refrigerant containing equipment Only certified personnel and companies can install, repair, maintain, recover and dismantle RAC systems A register with the quantity of purchased and recovered refrigerants (both at a certified personnel or company level and from at the distributors) available to the authorities Refrigeration System Logbook containing relevant historical data of the installation, maintenance and repair available for each system (a threshold to avoid small systems, like domestic refrigeration and air conditioning, could be evaluated) The above allows the checking and monitoring of the whole sector, whether the Service Technician and the company doing the job is competent and prevents loopholes in the certification system

12 Certification the numbers Number of certified personnel in different countries (2014) Country N of Service Technicians Australia (including automotive mechanics) Germany Italy Philippines United Kingdom

13 Certification the numbers the costs The certification costs vary quite largely between countries - even between developed countries - as they depend on: Paperwork behind the certification Registration procedure for public list Assessment organizational aspects Validation, confirmation procedures of the assessment from third party NB. Certification normally has to be renewed periodically, preferably every 5-10 years due to technological changes in components, equipment, refrigerants, standards and regulations

14 Certification the numbers the costs (2) Installer certification cost ( =Euro) Australia 800 Belgium 1,200 Czech Republic Finland 0 to 3,000 depending on training needs France 2,000-3,000 Germany 50 for people who already hold a master craftsman s diploma or certificate of apprenticeship in air-condition technology. Hungary up to 1,500-2,000 depending on categories and former level of certification Ireland Between 1,400 and 2,000 Italy Philippines 25 Portugal 750 Slovakia (training + eam and certification) Spain 2,000 Sweden 700-2,500 United Kingdom 500 to 1000 Note: some countries include training in the certification, the costs above are for certification only for the majority of countries. Ideally, certification and training costs should be left separate.

15 Training and certification worldwide CSG have over the last few years been deeply involved in helping developing countries improve living conditions, by improving refrigeration and air conditioning systems and processes, through capacity building and training technicians to install, repair, maintain and design numerous Certification Sessions with United Nations in Africa and Asia (Rwanda, Ghana, Tunisia, Eritrea, Benin, Gambia, Montenegro, Saudi Arabia, Turkey etc ).
