Investigation and Performance Testing of Mobile Leak Detectors for Mobile and Stationary Refrigeration Systems

According to Regulation (EU) No. 517/2014, systems containing fluorinated greenhouse gases must be tested for leaks at regular intervals (varying between 6 months and 2 years) depending on the CO₂ equivalent. In practice, mobile leak detectors are mainly used for this purpose.

To ensure the proper functioning of the equipment, Regulation (EC) 1516/2007 requires that refrigeration and air conditioning equipment and heat pumps with a charge > 3 kg of fluorinated greenhouse gases be tested for proper operation every 12 months. "The sensitivity of portable gas detection devices must be at least 5 g per year".

According to DIN EN 378-2 section 6.3.3.2, the detector must be calibrated at regular intervals according to the manufacturer's instructions.

The test procedure for at least annual inspections of the performance of mobile leak detectors and room monitors for halogenated refrigerants is described in DIN EN 14624.

For this check, use, for example, a testing device with a sliding or swiveling leak detector probe. The performance test includes:

• Test 1: static detection limit
• Test 2: dynamic detection limit
• Test 3: dynamic detection limit in contaminated environments
• Test 4: response time
• Test 5: recovery time
• Test 6: cross-sensitivity to other contaminants (in addition to the standard)

To determine the performance, adjustable calibrated test leaks are filled with the appropriate test gases (e.g. R134a, R1234yf) and placed in the test stand. We would be pleased to perform this test for you. The test performed is certified with a test report.
