Indeed, although the F-Gas Regulation requires equipment owners to address leakage issues, it does not offer technical advice on how to prevent leakage in existing or future systems.

Mainly as a result of poor maintenance, it is believed that some refrigeration systems may leak more than 20% of their charge to the atmosphere per year.

The investigations will cover Air Conditioning and Refrigeration equipments installed at retailers, commercial and industrial food processing sites.

The results of investigations will be analyzed to identify the main sources of refrigerant leakage, how these can be reduced, in order to identify key issues for action, such as:

  • Optimum system refrigerant charge;
  • Reasons for current leakage problems (design issues, service and maintenance practice etc);
  • Barriers to reducing leakage;
  • Recommendations for actions to reduce leakage, and the associated cost-benefit.

As a result, the IOR intends to publish of guidance notes for equipment owners on:

  • Why leakage matters and what it costs;
  • Common leak points;
  • How to identify leakage risk points in cooling equipment;
  • Key issues for specifying design and installation of new leak-free systems;
  • How to prevent and remedy leaks as part of regular maintenance;
  • Case studies of major leakage issues and reduction measures in various types of systems.
