Specific action Where it will impact Reason

Refrigerant phase out GWP Refrigerants >2500 [ie; R404A]

Take action on Highest GWP products

Refrigerant Phase down GWP Refrigerants <2500 [eg; 410A]

Encourage move to lower GWP refrigerants over time

New measure of environmental impact [CO2 tonnes equivalent]

Takes into account system volume as well as GWP

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

R32 and HFO’s Under EN378 they are recognised as a new category A2L’s

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]

Page 25: R32 Installer training - Air Conditioning Chesterfield & … · R32 Installer training . 2 R32 Installer training Section 1: Why Change to R32 ... High ambient R32 inverter flagship

Page 27: R32 Installer training - Air Conditioning Chesterfield & … · R32 Installer training . 2 R32 Installer training Section 1: Why Change to R32 ... High ambient R32 inverter flagship

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)

2. Amount of energy is expressed in Joules

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.

Page 38: R32 Installer training - Air Conditioning Chesterfield & … · R32 Installer training . 2 R32 Installer training Section 1: Why Change to R32 ... High ambient R32 inverter flagship

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.

Many suppliers are already providing R32 ready gauges

In fact Yellow Jacket gauges have been supplied to a number of distributors with R32 on dial for the past 2 years.

Please ask your supplier for a gauge that has R32 included on the dial.

Over the next period all gauges will have R32 on the dial as R410A only gauges are phased out.

Mastercool have R32 specifically enclosed motor fan cooled motor)

The RecoverXLT2-AP™ from Yellow Jacket has included an “ambient pressure switch” which stops recovery above ambient pressure for leaking systems to prevent pulling air into recovery cylinder also a three meter power cord

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.

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

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.
