GEA Refrigeration (Germany)
A review of CO2 in mid-sized refrigeration systems
Environmental concerns have led to an increased focus on natural refrigerants. The huge growth of transcritical CO2
systems, mainly in supermarket applications and to a lesser extent in industrial refrigeration, can be seen as an example of organisations looking at environmentally friendly solutions.
Gerritsen will share the results of a study on the application of CO2
in mid-sized refrigeration systems, traditionally the grey area in between commercial (HFC) and industrial (ammonia) refrigeration. He will present a transparent evaluation of yearly energy consumption of CO2
systems versus ammonia systems for different climates. In this comparison, he will also evaluate the possibilities for heat recovery, which appear to be quite different for CO2
compared to other refrigerants. He will also focus on safety aspects and total cost of ownership.
Gerritsen is the innovation manager of refrigeration technologies at GEA Refrigeration. He graduated from the Delft University of Technology in the Netherlands, where he studied mechanical engineering and specialised in refrigeration technologies. He joined GEA in 1988 and participated in many new technical developments, such as ammonia DX and CO2
From 2012 to 2015, Gerritsen worked as an R&D manager for one of the leading supermarket cooling companies in the Netherlands.
