The Refrigerant Handling 2079 Category 1 is our most popular option and qualifies candidates for charging and recovering for systems with more than 3 kg of refrigerant in them. Other categories are available upon request.
Holding a valid ‘F Gas’ qualification is mandatory for anyone handling F Gas refrigerants.
The 3-day course includes a overview of the F-Gas theory and practical prior to the exam.
This course is only suitable for experienced engineers with a good knowledge of the refrigeration cycle and practical skills including operating fridge valves, attaching gauge lines with minimal emissions and copper brazing purging with OFN.
Our 5-day and 10-day courses are available for engineers with less experience.
The 2-day F Gas course is also available for more experienced engineers who only want a refresher on the theory prior to the assessment.
Objective
To achieve the skills and knowledge necessary to obtain the City and Guilds 2079 (F Gas) Category 1 qualification in Refrigerant Handling.
Methodology
Practical skills will be revised and practised on the first day. On the second day a presentation/talk-through will be followed by training in specific topics as required by the candidates and practice in completing the paperwork needed.
The assessment day will comprise a practical test demonstrating the skills listed below and an on-line, multiple choice question paper for the theory.
Synopsis
The 3 day course includes the following topics:
• Units of temperature, pressure, mass, density and enthalpy, including
different states of refrigerant
• The basic theory of the vapour cycle and the use of pH diagrams
• The function of the major components, their performance and indications of
leakage
• The operating conditions and efficiency of a system
• Azeotropic and non azeotropic refrigerants
• The GWP (global warming potential) of refrigerants
• Energy efficiency and ozone depletion, including the Montreal and Kyoto
Protocols
• Identification of leakage points and the associated risks
• The legal requirements regarding the storage and transportation of
refrigerants, oils and controlled wastes
• The documentation and records which need to be made and kept and how to
complete them
• The hazards involved in handling refrigerants, oils and waste products
• The hazards involved in nitrogen pressure testing and flame brazing
Practical – you will need to demonstrate the following practical skills:
• Be able to braze and flare pipe
• Carry out and complete nitrogen pressure test
• Carry out and complete leak test direct and indirect
• Vacuum out system using vacuum gauge
• Prove system structure is sound and leak tight
• Charge system with non azeotropic refrigerants (over 3 kg for category 1)
• Prove system efficiency
• Produce commissioning document
• Complete a system log
• Recover refrigerant
• Drain oil from a compressor
• Produce waste documentation
• Ensure refrigerant traceability
