Cool Talks: An interview series with GCI network members

In our "Cool Talks" interview series, members of the Green Cooling Initiative Network and beneficiaries share their vision of Green Cooling. The GCI Network is an alliance of key players in the refrigeration, air-conditioning & foam sector. It comprises government institutions, international organisations and the private sector. They are united on one goal: the transformation of the cooling sector – for the benefit of people, the environment, and our shared future.

Cool Talk: “The training was very practical and fruitful”

21.04.2022 , News :

Mr. Ardalan Asadi is a representative of Fajr Fereidooni company. He participated in a Train the Trainers workshop on hydrocarbon refrigerants at the Iran Technical and Vocational Training Organization ITC Karaj in July 2019. Two-and-a-half years later, we would like to know how the training has influenced his work.

Mr. Asadi, what were the most important insights you gained during the hydrocarbon training?

During the workshop about the application of hydrocarbon refrigerants there were many important parameters which were considered and taught. The most prominent one that should be mentioned is the correct way of welding and connecting pipes. Due to the thermodynamic properties of hydrocarbon refrigerants, they have a low viscosity that makes us choose a smaller diameter in sizing piping.

Another point that can be mentioned is the difference between a welded joint and a screw connection: welded joints minimize the percentage of refrigerant leakage. This issue can be significant in the commercial refrigeration industry

Tell me, which aspect that you learned during the Train the Trainers workshop could you apply in the RAC sector in your country?

All the trained sections can be considered and become effective in our country – especially the part about energy efficiency. Another highlight is the low volume of refrigerant that is injected into the cycle. Moreover, the best layout of refrigerators and freezers which work with propane for shops.

Safety aspects

How have you been able to pass on knowledge about the safe use of natural refrigerants?

The Fajr Fereidooni Company has always had an eye on research and development in this field. This has always included a positive view of new and innovative systems in order to increase the energy efficiency as well as the protection of natural resources and of the ozone layer.

Due to the fact that some natural refrigerants are in class A3 of refrigerant standards, which means they are flammable, safety measures have to be taken at the time of injecting these refrigerants to the cycle. By creating and preceding training technical workshops under the company's infrastructure, we provide technicians with the necessary trainings and support services in Tehran and other cities.

Fajr Fereidooni refrigeration company

The Fajr Fereidooni refrigeration company (opens in a new window) is a designer and implementer of refrigeration systems and interior decoration for chain stores, hypermarkets, megamalls, restaurants, coffee shops, confectioneries, etc. After half a century of experience in the production of high-quality products, it is still growing. Relying on the latest expert knowledge and using the best available materials on the market, Fereidooni company seeks to build the best refrigeration equipment with high energy efficiency. Quality and innovation in production are two main decisive components of the company’s vision and goals. 

Contact with training participants 

Are you still in contact with the other Training participants? Have you exchanged experiences and knowledge?

Yes - Fajr Fereydooni refrigeration Company is always in contact with and in review of new systems with partner companies. In fact the policy of our company is based on interaction and knowledge exchange with domestic and foreign partner companies.

This has raised the technical quality of this company and other dear colleagues.

Especially in optimizing energy efficiency, protecting the environment and preventing global warming.

Future cooling sector

Mr. Asadi (on the right) and his colleagues are committed to Green Cooling.

Looking back on the Train the Trainers workshop, what is your best memory?

 

This training was very practical and fruitful in terms of technical concepts. What was truly important was to compare the performance of brazed connections and flared connections. In the pressure test with a flared connection, the leakage was maximum. However, doing the same test with brazed connection, the leakage was minimum. This result has a prominent role in commissioning and installation.

To conclude this interview I would like to know why are you committed to Green Cooling technologies?

Green technology in general focuses on looking at the green future of the planet.

Fajr Fereydoni refrigeration Company was one of the first companies of manufacturing commercial refrigerators and freezers which took actions in removing CFC carbon chloride refrigerants years ago and banned the use of R12 and R22 refrigerants since 2003. Currently, in the research and development plan, it often enters its products to the market with hydrocarbon refrigerants.
