AIR CONDITIONING SYSTEMS
COURSE 750: 3 DAYS
This course provides an introduction to the maintenance requirements of split-system air conditioning units. Candidates gain the knowledge and skills needed to perform the most commonly-occurring first-line maintenance tasks on these systems so that they can inspect them for damage and functionality, clean them, maintain them and recognise when an engineer needs to be called out.
PARTICIPANTS
Building services staff, caretakers, and those responsible for maintenance of hospitals, schools and care homes are ideally suited to this course. No prior air conditioning knowledge is required.
COURSE PRESENTATION
Candidates are given the opportunity to investigate all of the major components of a split system air conditioning unit, and to practice some of the first-line maintenance tasks. As with all of the courses that Technical Training Solutions provides, the emphasis is on safety with plenty of hands-on practical work.
COURSE OBJECTIVES
On completion of the course, participants will be able to
- understand the safety precautions and gain an awareness of the EU laws concerning the use, handling and disposal of refrigerants.
- state the impact of CFCs and HFCs on the environment
- understand the principles of air conditioning systems
- recognise the major components used in split system air conditioning systems
- carry out routine inspections of filters and understand the need to maintain hygiene and system efficiency
- demonstrate an understanding of the F-Gas regulations
- state the methods of leak detection
- understand the terminology used within split system air conditioning systems
- describe what is meant by ‘Superheated’ and ‘Subcooled’ liquids
- understand how to use a digital thermometer to check the correct functioning of a split system air conditioning unit.
Successful completion of the course leads to the award of Amicus / Technical Training Solutions competence certificate 750: Air Conditioning Systems.
What do candidates on the Air Conditioning course actually do?
The air conditioning course begins with a description of what typical commercial and industrial air conditioning systems physically look like, with an introduction to some of the terminology used to describe the main component parts. An explanation of how air conditioning systems function follows, with a description of the 'refrigeration cycle', the fundamental principle behind air conditioning systems. We then look at the component parts of air conditioning systems.

The candidates then learn about the principles of 'superheat' and some of the important principles involved in the operation of air conditioning systems, such as the use of thermostatic expansion valves and the maximum allowable system pressures. Candidates also learn about more practical issues, for example the recommended spacing of pipe supports etc.
 |
 |
 |
Practical exercises are interspersed in the theoretical part of the air conditioning systems course, for example we have real air conditioning components for candidates to work on and professional tools for making pipe connections.
 |
 |
 |
We then look at the methods by which leaks can be detected, how systems are evacuated and how refrigerant should be recovered.
 |
 |
 |
The candidates then practice using leak detectors, vacuum pumps and recovery units on the air conditioning course.
 |
 |
 |
We finish the air conditioning course by ensuring that the candidates understand the legal and ecological issues involved with working on air conditioning systems, in particular the climate change issues, the effects of fluorocarbons and the important issues involved in ozone depletion. This helps candidates to understand why for example, the F Gas regulations are so important.
