1. Technical, Vocational Education and Training andGood Service Practices in Refrigeration Michael MollerPraxis Vocationalmichael@praxisvocational.com
2. BackgroundThe TVET, RAC sector has:Experienced Trainers with existing skillsCurricular and resources out of date with current industry best practicesDiffering quality standardslicensing schemes in some countries however with differing criteriaNo regional consistency in certification processesNew and emerging technologies using flammable and natural refrigerantsNational policies introducing alternative refrigerants into the market
3. Background contextGuidance from the MLF:Decision 70/53/Rev1 of the ExCom: where the need for improvement of education of servicing technicians is mentioned in the context of better management of HCFCs and alternatives that would allow for avoiding emissions of high GWP gases and for easier acceptance of low GWP alternatives.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, air conditioning and heat pump systemsTherefore, the establishment of a sound, reliable and operational assessment and certification scheme for RAC technicians is one of the most important components of country’s HPMP.OEWG July 2019Identified Vocational Education as a keystone strategy for MP compliance and workforce development
4. GSP in the context of the Montreal ProtocolReducing direct emissions Recover/Reclaim proceduresVacuum and leak detectionFlaring and pipe joining systemsBarriers in TVETCurriculum needs to be updated to include alternative refrigerants and new service techniquesLack of physical resources for training deliveryTraining delivery mostly theoretical not Competency based (due to lack of resources)
5. GSP in the context of the Kigali AmendmentReducing direct/in-direct emissions Introduction of alternatives to HFC refrigerantsEncourage use of Low GWP alternativesEnergy efficienciesIntroduce policy mechanisms (certification and legislation) Barriers in TVETCurriculum needs to be updated to include instillation and servicing RAC equipment for energy efficiencyPhysical resources for training delivery need to focus on alternatives and demonstrate operational characteristics of alternatives (pressures and temperatures)Curriculum needs to include energy auditing as a tool for diagnosticsCurriculum needs to include safety standards for use of flammable refrigerantsAlternative Low GWP refrigerant demonstration machinesCertification procedures linking TVET with Government issued licenses (regional quality standards?)
6. CBT Assessment resources Documents type of evidence (RPL, workplace etc)Practical, theory and observed competenciesAligns with competency standards
7. Training machines that demonstrate operation of Low GWP alternatives:Familiarise technicians with the technologies (reduces hesitancy to use)Demonstrate operational characteristics of Low GWP alternative refrigerantsDemonstrate the transition from HCFC to Low GWP alternatives (retrofitting)CBT Physical resources
