Refrigerant Phase down GWP Refrigerants <2500 [eg; 410A]
Encourage move to lower GWP refrigerants over time

Encourage use the less refrigerant
Leak checking less often with lower ‘CO2 tonne equivalent’ systems
All Air Conditioning and refrigeration systems.
Encourage use of lower volumes and lower GWP refrigerants
Different properties of some lower GWP alternatives mean small changes to install procedure

Calculation based on R1234yf and R32.
When working with any gases various considerations need to be taken to ensure a safe working environment.
R32 is similar however there are a few extra precautions resulting from its mild flammability
They cover precautions relating to the ‘fire’ triangle
The precautions are simple
• Avoid a build up of gas
• Avoid sources of ignition
Even if all the right circumstances
come together then it is burns very slowly
Hence the new classification A2L
24
Safety considerations when using a gas
Source of ignition
Mix of refrigerant [in the right % with air]
25
When considering the build up of gas the following is important to consider;

Section 2: Standards 2.2. Safety considerations
26
Only a mixture of flammable gas with Oxygen between the Lower and Upper flammability limits could have any chance of ignition
Every flammable gas needs oxygen to burn; but how much oxygen depends on the gas
A flammable gas can only burn between LFL & UFL (lower flammable limit & upper flammable limit)
Only a mixture of between 14% and 31% R32 in the air can burn

We have just considered that for R32 to burn it must exist in a mix between 14% and 31% with Air. However when we consider the ‘Fire triangle’ then it also requires Heat Energy.
MIE (minimum ignition energy)
1. varies depending on the gas
2. Amount of energy is expressed in Joules

Mechanical spark (steel tool drops on concrete floor) < 0.0006J

Section 3: Working with R32 3.1. Refrigerant properties
ATEX directive 2014/34/EU
The ATEX directive is the name commonly given to the two European Directives for controlling explosive atmospheres.
Explosive atmospheres in the workplace can be caused by flammable gases, mists or vapours or by combustible dusts. Explosions can cause loss of life and serious injuries as well as significant damage.
The Dangerous Substances and Explosive Atmospheres Regulations 2002
Dangerous substances can put peoples' safety at risk from fire, explosion and corrosion of metal.
DSEAR puts duties on employers and the self-employed to protect people from these risks to their safety in the workplace, and to members of the public who may be put at risk by work activity.
37
Section 2: Standards 2.3. Maximum allowable charge
For AC system using R32 (A2L gasses) this standard only becomes applicable when a system design exceeds the Lower flammable limit if the gas was to escape from a system.
38
Section 2: Standards 2.3. Maximum allowable charge
Stage1 • Check room size vs charge size (service manual)
Stage 2
• Confirm that the system charge does not exceed LFL if all the gas were to escape into the room
Stage 3
• When charging in a confined space always use an exhaust fan to ensure that build up of refrigerant cannot occur.

Current Promax machines are able to be used with A2L’s however this applies to specific models on the condition that a defined set of operating instructions are followed, please ask your supplier for additional details.
47
It is advised to use the recovery pump together with an EX ventilator, to avoid accumulation of R32 gas in case of leakage.
The air should be extracted not just moved around surrounding area

Please use a different recovery cylinder for R410A and R32 otherwise you will mix the refrigerants and they will have to be disposed of [at a charge to the installer]

All flammable gas cylinders have left thread. This adapter piece converts left thread to right thread, for use of manifolds.
Ask your supplier for an adapter when you pick up the cylinder
Gas is now available from all the major distributors, please ask for details from your supplier.

During charging flammable gasses, the leak detector must be permanently ON to indicate the presence of the gas and alert when LFL (lowest flammable limit) is reached to give the installer the chance to act.

ZX-1 / 1A Detects ALL halogenated refrigerants
Sensitivity less than 3g/year, instant response
Tri-colour leak size indication display
The ZX-1 eliminates false alarms from moisture,
cleaners and solvents, and allows you to locate even the smallest refrigerant leak without misleading feedback.
Reliability is a key feature of the ZX-1. The unit is equipped with a sensor failure indicator, a battery test function giving true voltage indication, and a low battery indicator.
XP-1A A2L refrigerants
> Variable frequency audible alarm
> 14” flexible stainless steel probe with Teflon™ liner
> Constant power indication
The TIF XP-1A features a mechanical pump which ensures that moving air from the immediate environment is continuously flowing over the sensing tip. This increases sensitivity and heightens leak detection.
The sensing tip is monitored by the microprocessor 4000 times a second and can detect leaks down to 3gr of refrigerant per year.
