} Combustion will not occur unless three conditions are met, Refrigerant concentration, constant oxygen, and an ignition source. Refrigerant concentration Area 14 to 30 vol.% (0.3 to 0.6 kg/m 3 ) R32 Constant oxygen Ignition source Minimum Ignition energy 30 to 100 mj (Static electricity : 1.25mJ)
How Flammable can R32 be? There is not enough concentration to ignite even if all the refrigerant should leak from 7.1kW class model in an approximately 7m 2 room. 1.8m Refrigerant concentration area 14 to 30 vol.%
Even if ignited, the flame propagation speed is slower than the speed of a person walking. 4 km/h R32 R32 combustion speed Approx 1.9 km/h The risk of fire spreading is quite low.
} Three items engineers considered for fire prevention Construction that makes refrigerant stagnation minimised Electrical parts have been designed to make ignition difficult non spark components Chassis design makes fire propagation difficult The risk of fire has been reduced.
Releasing refrigerants into the atmosphere is illegal Refrigerators, freezers and air-conditioning units contain refrigerants that damage the environment. Synthetic greenhouse gases (SGGs) are now widely used as refrigerants in fridges and air-conditioning units. Under the Climate Change Response Act (CCRA) 2002 it is illegal to release SGGs into the atmosphere. (This came into effect on 1 January 2013.) Refrigerants that are ozone-depleting substances are being phased out under the Ozone Layer Protection Act (OLPA) 1996. It is illegal to release these refrigerants into the atmosphere. The Environmental Protection Authority has enforcement powers under the CCRA and OLPA. If you release SGGs or ozone-depleting refrigerants into the atmosphere, there are serious penalties. It's important that you know what refrigerants the appliances you work with contain, and that you don't release these into the atmosphere.
Approved fillers Anyone filling compressed gas containers with gas must be an approved filler. This requirement applies to all compressed gases, including air. What is an approved filler? An approved filler is someone certified to fill compressed gas containers, such as: 1. industrial gas cylinders 2. liquefied petroleum gas (LPG) cylinders 3. self-contained underwater breathing apparatus (SCUBA) 4. self-contained breathing apparatus (SCBA) 5. fire extinguishers 6. aerosol cylinders 7. paintball cylinders
} It is illegal to retrofit or convert a refrigeration or air conditioner appliance with a refrigerant it is not designed for. } Electrical safety regulators advice on converting systems } and equipment is: 1. If equipment has not been confirmed as being designed, manufactured and tested to be compliant to relevant electrical safety standards for use with the proposed refrigerant then conversion of the equipment or use of the proposed refrigerant should not occur. 2. All domestic electrical appliances must be shown to comply with the relevant electrical safety product standard for use with the proposed refrigerant.
} Customers to have completed a recognised flammable gas fillers course and be certified. } Attended a Fujitsu R32 Training Course } Completed a test questionnaire and passed. } Prove ownership and use of torque spanner set } Sign the R32 product supply agreement
