Does the F-Gas proposal have a direct impact on your work?
JP. B: Yes. After7 or 8 years of hearing about the tax on R-404A, this is the first time that texts have actually been presented. We therefore had to react immediately. In November 2012, when the F-Gas proposal came out, we were in the middle of negotiations for two export agreements planned with R-404A. Following comparisons and thermodynamic studies, we made the decision to install PerformaxTM LT to meet tomorrow's requirements today. I was surprised to see a 5 to 6% gain in overall energy compared to R-404A on booster.
How did you find out about PerformaxTM LT?
JP. B: I got to know about PerformaxTM LT through the first installation that was carried out in France in 2010, at the Super U near Périgueux. I knew the refrigeration engineer who carried out the installation and I therefore found out about this fluid from this refrigeration engineer and then secondly from Climalife to obtain the thermodynamic characteristics.
You mention the energy saving from PerformaxTM LT, more specifically, what are its advantages in your opinion?
JP. B: I am optimistic about this new fluid because PerformaxTM LT does not require any change of equipment and yet meets the requirements of the forthcoming regulation. Furthermore, in the installations that I have already been able to carry out, I have found improved performance in above zero refrigeration and a reduction of electrical power in below zero refrigeration.
What arguments would you put forward to your clients?
JP. B: I would first of all mention its GWP, which is similar to R-134a. Then the simplicity of its implementation compared to R-404A, without the need to increase the duty of the compressors. In addition, I would emphasise how easy it is to use for refrigeration engineers. And finally, I would explain to my customers that with PerformaxTM LT, the heat diffusors are reduced thanks to the higher temperature levels in heat recovery.
What will your recommendations be for the future?
JP. B: The purpose of our firm is to provide technical support for all stakeholders, users and project managers of refrigeration stations. In view of these developments, we will adapt "What we can do today is something that we couldn't do yesterday." We should recommend suitable solutions for controlling electricity consumption as we did in the past with the booster system (energy saving, increased output, doubling the life of a below zero refrigeration compressor,...) but always with the aim of simplicity.
Regarding HFO, have you any questions yet?
JP. B: I have already heard about HFO and I am very interested in this new generation. Nonetheless, I wonder about its flammability, which risks delaying it being put into application...
