Apstrakt

The quote of Winston Churchill, the start of the end of the beginning, can be used to describe the situation after the news on October 5^th broke out announcing that The European Parliament and the Counsil had reached a provisional deal which included specific bans on the use of various fluorinated compounds and a complete phase out by 2050. The writing on the wall is a wakeup call for those that have not yet understood that the end is nearer than what meets the eye. Although the announcement was provisional it still reveals what can be expected in the future.

The news must have been a bitter pill to swallow for those who have not started looking in to fluor free alternatives in due time and now have to hast through what others already have done and ready to take the markets.

For the environment the ban means a doublet fold reduction on the CO₂ emissions:

During the manufacturing of the fluorinated refrigerants the emissions of CO₂ equivalents are about 3-4 times higher than for some natural refrigerants and for the new series marketed as HFO it can amount more than 10 times the CO2 emissions producing naturally occurring working fluids.

In many cases refrigeration, air conditioning and heat pump systems with naturally occurring working fluids are about 10 to 15% more energy efficient than systems based on fluorinated fluids.

The big questions for many companies is what and how do we can handle the flammability of HC and other challenges that comes with naturally occurring working fluids? This is what this paper will dive more in to and give some answers to the issues that need to be considered.
