Hello! In the last week of April, we attended the 10th IIR Conference on Ammonia and CO2 Refrigeration Technologies in Ohrid, North Macedonia. I was, inherently, expecting a scenic beauty in the Balkans but honestly speaking, Ohrid was more than my expectations (despite a long distance from Skopje :) ). The city is located in a wonderful area where high mountains and an amazing lake meet up; therefore the climate is really nice.

The conference was my first conference under DTU affiliation with the current projects that I have been involved in. At the conference, we presented two of our recent works; i) Computational fluid dynamics simulations of two-phase R-744 ejectors and ii) Mini review on technological map of R744 heat pumps. In the first presentation, we presented our recent CFD results for a specific R-744 ejector while the second presentation was mostly related to the recent literature about R-744 heat pumps with challenges and potential solutions. Both presentations got more questions than I expected hence I think we did a quite good job there :)


It was a very nice experience and I would like to thank the Danfoss team for their support on both studies. Once the online versions of the conference papers will be available on the IIR website, I will update this webpage with the links. For now, there are some photos below (yes, they are free unlike the IIR conference proceedings webpage);
