With CO2 transcritical retail stores in warmer European climates expected to hit 100 in the next two to five years thanks to technology developments like adiabatic cooling, ejectors and parallel compression, Bulgaria represents a potential growth market for the technology. Although there are still barriers to overcome in the EU Member State positive developments are on the way with leading retailer Kaufland seriously considering CO2-only systems.
“We are currently conducting system tests, for the countries in which Kaufland is active, to determine to what extent a CO2-only system can be best realised. Romania and Bulgaria are included,” he said.
“We have experienced how important parallel compression and gas subcooling is for our region. The Bucharest-Vulcan project relies on subcooling, without which the plant works in very high load conditions. As soon as the chiller is working we can observe a clear difference and improvement in operation,” he said.
