Emissions of refrigerants present and future in EU
Similar or even tougher trends in
other regions
no refrigerant
represents the ideal
solution in all cases and
for every equipment –
each cooling application has to be looked at in its
own merits and a
professional choice must
be made taking into
account many more factors than simply GWP

Some Applications of low GWP alternative refrigerants
From AREA guidance
on LOW GWP
refrigerants
*more applications for
HFOs and HFO blends will
probably be developed
with full commercialisation
of the refrigerants
Pros / Cons refrigerants
Every refrigerant has his own application
Contractors’ training with low GWP
refrigerants: mind the gap!
The use of HFCs is legislatively decreased
and consequently the use of natural
refrigerants is pushed, there will be a gap
between training offer and training needs
resulting in a shortage of trained contractors
The revision of the F-Gas Regulation include measures in favour of a decreased use
of HFCs in RACHP equipment. Such measures would, in turn, result in an increased
use of alternatives, namely low GWP (global warming potential) refrigerants, and in
particular the so-called “natural refrigerants” (CO2, hydrocarbons and ammonia). Mindful of the key role played by contractors in the safe, efficient and reliable
functioning of equipment working with natural refrigerants, AREA sought an overview
of the availability and level of training in the EU.
Solution could be starting from the F-Gas certification of personnel
adding modules for natural refrigerants

NOU/Industries/Association/Vocational Training
• Approaches for regional cooperation to achieve
effective training
Why creating
Training, Assessment, Certification
Training and Certification is an important tool and the only way to reach the
competence necessary to handle refrigerants and the systems
Legislation-driven:
• Environment 1. Reducing Refrigerant Emissions, GHG, ODS
2. Increasing energy efficiency (reducing CO2)
• Safety
Customer-driven:
• Wholesalers, distributors, big customers … require environmentally friendly and
energy efficient products
• Protects the interests of customer through providing services according to applicable standards
Certification of the personnel and of the companies
who handle air conditioning, refrigeration and
heat pumps equipment should be necessary To buy refrigerant
To install, repair, dismantling
Why creating
Training, Assessment, Certification (2) Training and Certification will also play an important role for the sustainability
of the associations, as it could be an important income stream both through
the training and the certifications organized by the association.
The associations’ role in certification could be also:
•to work alongside the government to set the rules, certification schemes and
regulations
•a third party policing the correct implementation of the regulation
•certification body who guarantees the high standard of the certification •certification body who issues the certification, renewing periodically
•the body who keeps the list, register and the records of certified technicians and
companies
Why creating
Training, Assessment, Certification (3)
It is recommended that only Competent and Certified
Technicians holding a certificate will be allowed to:
• install, maintain, repair, recover, dismantle RAC
systems containing refrigerants
• buy the refrigerant as a proved Certificate holder
NB. Informal Sector buys Refrigerant only if holding the
certification. This will stop the development of an informal
sector and in particular preventing the bad behavior
(accidents, emissions) which is most common in this sector.
Certification
is the best practical method to
verify the competence of personnel
handling refrigerants and to ensure
the correct installation, maintenance, repair and
dismantling of a refrigeration,
airconditioning and heat pump
systems.

AREA can help with Standards,
Legislations and Projects we already
implemented in EU (cronological order)
• EN13313
Refrigerating systems
and heat pumps.
Competence of
personnel
• Leonardo da Vinci EU
project
• CE 303 (new version)
• Real Alternatives EU
project
• This European Standard defines the
activities related to refrigerating circuits and the associated competence profiles and establishes procedures for assessing the
competence of persons who carry out these activities.
These standards,
legislations, projects are All
linked together (and with EN378)
Natural persons (personnel) carrying out certain tasks on certain types of equipment must be
certified or qualified.
Equipment
Stationary refrigeration, air conditioning, heat pump and fire protection equipment
Refrigerated trucks (above 3.5 t) and trailers
Air conditioning equipment in road vehicles
Tasks
a) Installation, servicing, maintenance
b) Repair
c) Decommissioning
d) Leakage checking
e) Recovery
Who needs to be certified?
(1 - Personnel)
*some countries worldwide offer the certification of companies. It is likely that developing countries could
use a different method to ensure the compliance of the requirements described below, for example provided that the single service installer, as self-employed person, provides the compliance
Companies carrying out certain tasks on certain types of equipment for other parties must
be certified.
Equipment
Stationary refrigeration, air conditioning, heat pump and fire protection equipment
Tasks
Installation, servicing, maintenance
Repair
Decommissioning
Companies should fulfils the following requirements
(a) employment of personnel certified in accordance with Article 5, for the activities
requiring certification, in a sufficient number to cover the expected volume of activities;
(b) proof that the necessary tools and procedures are available to the personnel engaged
in activities for which certification is required.

Lusophone Countries) around 20
technicians has ben certified
• Eritrea around 20 technicians
• Tunisia

Training, Assessment (2)
Training and certification for Ghana on
natural refrigerants: Hydrocarbons HC
a delegation of technicians from Ghana
received theoretical and practical training on
the safe handling and design of equipment
with hydrocarbon refrigerants at the
headquarters of the Centro Studi Galileo,
Casale Monferrato, Italy. The training is in line
with the country’s efforts to phase out HCFCs
and establish a safe hydrocarbon and natural
refrigerant use culture
The Gambia (LVC)
Expected Outcome: Technical and financial support on replacement
refrigerants, and reducing greenhouse gas emissions and
operational costs, is ensured.
Aim: To pilot a technology transfer mechanism through the establishment
and operation of the technical support mechanism, while introducing
innovative technologies to this sector.
The technology focus will be on energy efficiency improvements;
reduction of ODS leaks and reduction of contaminated refrigerants;
and introduction of two types of demonstration systems – one using
hydrocarbon refrigerant for retrofits and a second full-scale CO2
industrial or commercial unit with cascade – to be piloted in a
training environment.
