Course programme

Details

Days 1-7 are taken up with 50% theory and 50% hands on practical experience

Day 8 is taken up with up to 4hr practical assessments and up to 2hr closed book online GOLA exam

The course is held at our Training Centre in Doncaster.

Candidates will be issued with a full set of City & Guilds 2079 study notes and practical assignment folders at the start of the course.

Benefits

This course has been written specifically for those who have little or no previous experience with refrigeration and air conditioning. The course will benefit candidates who have some technical background in other disciplines and wish to cross train into refrigeration/air conditioning. It is also suitable for refrigeration engineers who wish to re-affirm their skills and comply with the new F-Gas Regulations and be able to handle refrigerants safely and competently.

The environmental and legal implications regarding Safe Refrigerant Handling makes this course essential for persons directly or indirectly connected with refrigerants. (Designers, managers, installers, service and maintenance engineers, non-refrigeration engineers wishing to cross train, etc).

Successful candidates will be qualified to undertake leak checking, recovery, installation, service and maintenance of equipment.

Learning Outcomes

There are nine learning outcomes from this course. The candidate will be able to:

1. Identify basic systems, terms, principles, units and how these relate to theory and thermodynamics of vapour compression cycles and refrigerants

2. Identify the causes and effects of global warming and climate change

3. Identify causes and effects of ozone depletion

4. Identify stationary refrigerant, air conditioning and heat-pump system components, functions and leakage risk

5. Identify the hazards and safe working practices for the installation, commissioning and handling of refrigerants

6. Fabricate and examine pipework

7. Undertake pressure testing, evacuation and record completion

8. Undertake refrigerant charging, leak checking and record keeping

9. Undertake recovery of refrigerant and oil and prepare for disposal.
