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

Common Causes of Leaks Specification Installation Commissioning Maintenance

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

Success Stories Retraining – condenser maintenance Training – leak reduction These improvements are not due to training alone Training is one part of a successful strategy Source, Space Engineering Services, UK

A Holistic Approach Less leaks Less energy Training: Knowledge Equipment Effective procedures Working together Desire to change Practical
