The Fairy Tale of Key Figures:
Which demands on refrigeration and
large air conditioning plants are truly relevant
Oliver Bötticher, born in 1977, is a skilled refrigerating plant engineer. After his training, he worked as service technician for various companies in the field of air conditioning and refrigeration. In 2007, he joined Johnson Controls Systems & Service GmbH, where he first served as service project manager and later as sales engineer.
Since 2016 Bötticher has been key account manager for industrial refrigeration with Stulz GmbH, a worldwide leading system supplier in the field of air conditioning solutions. Working at a strategic and operational level, he focuses on industrial project development and new product development as it relates to industrial cooling.
The Fairy Tale of Key Figures: Which demands on refrigeration and large air conditioning plants are truly relevant
Air conditioning consumes most of the energy required by non-residential buildings. As operating managers seek to achieve maximum efficiency, the importance of employing custom solutions increases. Decision makers need to consider the whole system, not just single components. In many cases, glycol systems can work more efficiently than pure cold-water systems. We will look at the free cooling system of a data center, and compare glycol and glycol-free systems.
To reduce the CO² levels in refrigerants, the EU developed an exit scenario (phase down) in 2014 and stipulated it in an EU-wide regulation. The phase down scenario includes bans for marketing HFC refrigerants and shows a successively artificial shortage of refrigerants containing HFC with a high CO² equivalent (GWP value = global warming potential).
How does this “phase down” work, which refrigerants are affected, and which requirements result from the new refrigerants for planning and operating companies? This lecture will deal with these questions and provide real world answers.
