Deciphering trends in technologies within the scope of Industrial Refrigeration

In a free-wheeling interview, Carsten Dahlgaard, Sr Director – Sales, Industrial Refrigeration, Danfoss (Denmark), speaks to Ranjana Konatt, Editor (Brand Positioning) on the trends within the industrial refrigeration sector…

Could you elaborate on Danfoss and its work within the energy efficiency sector? Concerning international markets, how is China different from Europe? 
At Danfoss, we have a passion for energy efficiency. The things that matter in a cooling system is the system-type, the kind of refrigeration, and the requirement concerning installation. If you compare markets, China focuses a lot on safety, and Europe is all about energy and the cost of ownership, reliability and safety standards. Today, the focus is not on how the market is foreseen but on how customers change installation procedures depending on the client’s requirement.

What are the trends in the industrial refrigeration sector globally? Are we seeing the safety and the total cost of ownership as important facets to growth within the sector?   
For industrial refrigeration, the trend is that globally we are seeing that safety and the total cost of ownership are drivers within the industry, irrespective of the country we are in. For instance, concerning industrial refrigeration, we have five-points that we keep in check- global warming, safety, reliability, cost and efficiency. All these five points are used in industrial refrigeration globally. There are a lot of things going on politically concerning global warming. As we can see here there have been agreements made on calling out refrigerants. One of them we have here is R32 a new refrigerant for air-conditioning. Today, we need refrigerants that are green from the industry side.

What are the latest shifts we are seeing in solutions from the industry side?  
If you take into account larger systems, we see CO2 TC systems, and they come from supermarkets. We have a green profile on ammonia and a high-efficiency. We have a graph on kilowatt cooling and also have nearly 29 kilos of ammonia. Concerning the drivers and the reactions for industrial refrigeration, energy efficiency is a hot topic and we are aware that the cost to power will not decrease. District heating and cooling is another method adopted by developed countries to be efficient with energy. We have seen the installation of large district cooling towers and projects in Denmark. With this we can detect and we have controllers in place in case of anything.
