All air conditioning/refrigeration systems containing more than 3kg of fluorinated refrigerants (f-gases) must be properly monitored and maintained at least every 6 months to minimise leaks.
This means that some single split systems, all multi/vrf systems and all chiller installations must be under planned maintenance with an accredited air conditioning contractor registered with ACRIB/REFCOM.
Energy Efficiency Inspections (TM44 Report / EPBD Energy Performance Building Report / ACIR Air Conditioning Inspection Report)
All air-conditioning systems with an effective rated output of more than 12kw (or combined system output) must be regularly inspected by an Energy Assessor. This includes any split / VRF / Chiller / AHU used for comfort cooling – not process or machine cooling (close control / server rooms etc). The inspections must be a maximum of five years apart. less
The regulations require the first inspection of the affected air-conditioning systems to be carried out as follows:
- for all systems first put into service on or after 1 January 2008, the first inspection must have taken place within five years of the date when it was first put into service
- for other air-conditioning systems, where the effective rated output is more than 250kW the first inspection must happen by 4 January 2009
- for other air-conditioning systems, where the effective rated output is more than 12kW the first inspection must happen by 4 January 2011
From 4 January 2011, if the person in control of the air-conditioning system changes and the new person in control is not given an inspection report, the new person in control of the system must ensure the air-conditioning system is inspected within three months of the day that person assumes control of the system.
