Status of national legislation on F-gasses in Denmark 2008
Frank Jensen
Danish EPA, Chemical Division
BACKGROUND
1996 The Danish Minister for Environment states the following:
”I want a phase-out in ten year’s time in new equipment or
products within the cooling industry”
HOW DENMARK DID IT
Tax: Adopted by Parliament December 15, 2001
Phase-out: Signed by the Minister for the Environment July 2,
2002
DOES IT WORK ?????
Simple answer YES
Nuremberg, 14 October 2010
Status of national legislation on F-gasses in Denmark 2008
Frank Jensen
Danish EPA, Chemical Division
STATUS 2008
Dialogue with industry and organisations
Exemptions has to be well-defined
Industry has to meet the challenges in a positive way
- without trying to find loopholes
10 kg limit has been the greatest challenge
CONCLUSIONS
Very clear political signals and support are essential
Use of non-HFC alternatives is possible for most applications
Need flexibility from the authorities (within well-defined limits)
Significant reductions can be achieved
- without extraordinary economic costs

Educational challenges
… when dealing with CO2 and other natural refrigerants
Issues
Current skill level of the industry
CO2 expertise is critical to the growth potential of CO2
What the industry needs to do to get up to speed in order to implement CO2 systems
Effective guidelines for designing and implementing a CO2 system
Competent instructors
Training facilities and equipment
Much larger switch-over within refrigeration trade compared to phase-out of CFC
Important for everyone to start “early” and obtain their own experience
Nuremberg, 14 October 2010
Visits and lectures on new cases
Several meetings and seminars held on new cases with HFC free cooling
A 2-day conference called ”Danish days of Refrigeration” is held every
year with 2-3 parallel sessions - and exhibition
A very effective way to transfer knowledge and experience from demo systems!
Typically arranged by two Danish Refrigeration Associations
(“Selskabet for Køleteknik” and “Dansk Køleforening”)

A new international neutral technological un-political and transparent platform is
being established by DTI:
”International Information Centre for Sustainable Refrigeration and Heat
Pump Technology” (ICST)
For everybody, who deals with all types of refrigerant applications
A global alliance for “the right selection of refrigerant for the application”
The primary tool is to give everybody worldwide access to updated network and

Applications with natural refrigerants in Denmark
General impression
Ammonia NH3 (R717, R723)
Standard for industrial applications – just as before
Chillers for A/C
Units for large heat pump installations
HydroCarbons HC´s (R170, R290, R600a, R1270)
Air or water cooled units for applications with indirect systems
Heat pumps
Carbondioxide CO2 (R744)
Few subcritical and mostly transcritical CO2-units for supermarkets, industry,
A/C, heat pumps, indirect systems, …
Systems with natural refrigerants are available and being used for many
applications – designed according to standards and legislation

Smaller plants than before are built in small numbers
HydroCarbons HC´s (R170, R290, R600a, R1270)
Decreasing activity in general, but increasing activity for chillers and maybe heat
pumps, due to high COP’s
Carbondioxide CO2 (R744)
Relatively high and increasing level of activity, components available, transitional
period over.
Subcritical applications is OK, only few can design and build transcritical
systems.
Fear for complexity and high pressures is decreasing.

HydroFlouroCarbons HFC´s (R134a, R404A, R507C, R410A, R507A)
Decreasing activity
Still standard type of refrigerant for ”small” systems (150 g < charge < 10 kg)
Typically up to 2-3 systems in parallel - each with less than 10 kg charge.
Still a lot of brine systems are made in special ”Danish Versions” with charge
under 10 kg
Refrigerants and components are available …
Only few and small contractors are ”hit” hard by the danish legislation
Wants same legislation as in other countries – no special regulations in DK

According to installers (contractors)

Jensen
Ammonia

Division
Around
10-15EPA,
% ofChemical
companies
use ammonia, increasing trend
HydroCarbons HC´s (R170, R290, R600a, R1270)
Only few companies work with HC´s
Carbondioxide CO2 (R744)
More than 25 % of the companies now have a lot of experience with CO2 and are
capable of handling CO2-designs similar to designs for other refrigerants.
Energy efficiency of CO2-systems is now being competitive with previous levels of
similar HFC-applications.
HydroFlouroCarbons HFC´s (R134a, R404A, R507C, R410A, R507A)
Everybody are using HFC´s
Danish installers have gained competence and know how to select refrigerant
and design systems for normal applications
Nuremberg, 14 October 2010
Final remarks and conclusions
The presentation has given a picture of todays situation and experience in Denmark:
 DK authorities have added tax on HFC s and phase-out HFC s since 2006/2007
 Authorities have requirements for competence of technicians and companies
 Danish EPA: Regulations with tax and phase-out worked
 Needed: Competent companies and persons, mature fully developed technology
 Instruction and training needed to give and build up competence to installers
 Visits and lectures about new cases are very effective for transfer of experience
 Information Centre for HFC Free Cooling offers assistance - free of charge
 Mc Donald´s first HFC-free restaurant has been in operation in Denmark since 2002
 Systems with natural refrigerants are available and being used for many applications
 Refrigerants and components are available
 Wholesalers wants same legislation as in other countries – no special DK-regulations
 Activity levels; Ammonia
( ), HydroCarbons
( ), Carbondioxide
( )
 Installers know how to select refrigerant and design systems for normal applications
 Refrigeration business have passed transitional stage and now works ”normal”
