15. Leak detection methods

    • The following leak detection methods are deemed acceptable for systems containing flammable refrigerants:
    • Electronic leak detectors shall be used to detect flammable refrigerants, but the sensitivity may not be adequate, or may need re-calibration. (Detection equipment shall be calibrated in a refrigerant-free area.)
    • Ensure that the detector is not a potential source of ignition and is suitable for the refrigerant used.
    • Leak detection equipment shall be set at a percentage of the FL of the refrigerant and shall be calibrated to the refrigerant employed and the appropriate percentage of gas (25 % maximum) is confirmed.
    • Leak detection fluids are suitable for use with most refrigerants but the use of detergents containing chlorine shall be avoided as the chlorine may react with the refrigerant and corrode the copper pipe-work.
    • If a leak is suspected, all naked flames shall be removed/ extinguished.
    • If a leakage of refrigerant is found which requires brazing, all of the refrigerant shall be recovered from the system, or isolated (by means of shut off valves) in a part of the system remote from the leak.
    • Oxygen free nitrogen (OF) shall then be purged through the system both before and during the brazing process.

16. Removal and evacuation

    • When breaking into the refrigerant circuit to make repairs – or for any other purpose – conventional procedures shall be used.
    • However, it is important that best practice is followed since flammability is a consideration.
    • The following procedure shall be adhered to:
    • Remove refrigerant;
    • Purge the circuit with inert gas;
    • – Evacuate;
    • Purge again with inert gas;
    • Open the circuit by cutting or brazing.
    • The refrigerant charge shall be recovered into the correct recovery cylinders.
    • The system shall be “flushed” with OF to render the unit safe.
    • This process may need to be repeated several times.
    • Compressed air or oxygen shall not be used for this task.
    • Flushing shall be achieved by breaking the vacuum in the system with OF and continuing to fill until the working pressure is achieved, then venting to atmosphere, and finally pulling down to a vacuum.
    • This process shall be repeated until no refrigerant is within the system. Whenthe final OF charge is used, the system shall be vented down to atmospheric pressure to enable work to take place.
    • This operation is absolutely vital if brazing operations on the pipe-work are to take place. Ensure that the outlet for the vacuum pump is not close to any ignition sources and there is ventilation available.

17. Charging procedures
