2. Outline How refrigerant leakage reduces efficiency
Common causes of leaks
Technician training for energy efficiency and leak reduction
Success stories

3. A Leaking System … A leaking system
Has less cooling capacity
Has a greater temperature lift
Runs longer
Impact on COP of leak very dependent on
Leak amount
System type
Refrigerant
Load and ambient
IoR paper Impact of refrigerant charge on the capacity and efficiency of a system, containing low GWP refrigerants
Presented February 2018, UK

4. Common Causes of Leaks Specification Installation Commissioning
Maintenance

5. Technicians Need to Know …
How to reduce leak potential
And how to leak test effectively
How to check / use leak test equipment
How a system should work
And what effects efficiency
Importance of maintenance and how to effectively maintain a system
That what they are doing really matters!
EU F Gas Qualification – example of effective scheme
Training and theory / practical assessment

6. Success Stories Retraining – condenser maintenance
Training – leak reduction
These improvements are not due to training alone
Training is one part of a successful strategy
