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 2-day course includes a overview of the F-Gas theory only prior to the exam and is the minimum length of training we’d advise for those sitting the 2079 assessment.
This course is only suitable for experienced engineers with a good knowledge of the refrigeration cycle and competent practical skills, including operating fridge valves, attaching gauge lines with minimal emissions and copper brazing purging with OFN.
Our 3-day F Gas course offers additional practical training, the 5-day and 10-day courses are also available for engineers with less experience.
Objective
To achieve the skills and knowledge necessary to obtain the City and Guilds 2079 (F Gas) Category 1 qualification in Refrigerant Handling.
Methodology
The F Gas theory will be revised on the first day with a presentation/talk-through, 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 2 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
