Event Details
Designed for experienced engineers who need to renew their F-Gas category 1 qualification or, engineers that seek extra theory training. The overall objective of the course is to understand how to work with refrigerants safely, reduce any refrigerant loss to atmosphere, reduce any refrigerant leakage and ensure systems are operating efficiently. The 2-day course consists of; The theory of how refrigeration systems operate and practical advice on completed the relevant paperwork. Practical assessments, as shown below, as well as an online multiple-choice questionnaire to ensure the candidates have an understating of refrigeration systems.
Engineers attending the course have to be able to do/know the following:
- Know the units of measurement used for temperature, pressure, mass, density and enthalpy, including different states of refrigerant.
- Recover and recharge refrigerant
- Strength and pressure test with the use of OFN
- Use brazing equipment and flare copper pipe
- Understand the basic theory of the vapour compression cycle and the use of a PH diagram
- Know major components and how they relate to a systems operation and how to identify potential for leakage
- Operating conditions and efficiency of refrigeration systems
- Azeotropic and non-zeotropic refrigerants
- Understand Ozone depletion including the Montreal & Kyoto Protocols and how they impact on our industry
- Identify leakage points, identification of and associated risks.
- Legal requirements for the storage and transportation of refrigerants, oils and controlled waste including documentation and records that need to be kept
- Understand the hazards involved in handling refrigerants, oils, hazardous substances and waste products
- Understand the hazards involved in using nitrogen for pressure testing and flame brazing
