Doing It All Efficiently with CO2 Refrigeration Anywhere in the World

This presentation examines the benefits of Evaporative Condensers/Gas Coolers (EC/GCs) where the cooling medium temperature is the Ambient Wet Bulb Temperature (AWBT) and not the ambient dry bulb temperature as is the case with air cooled gas coolers. A 1% incidence AWBT of 28°C is not exceeded in 98% of the world’s climates. At a AWBT of 28°C it is relatively easy to achieve a gas cooler CO₂ exit temperature 31°C and even 30°C at part load. This means that efficient CO₂ refrigeration may be operated all over the world with the use of EC/GCs.
