The biggest changes in the Air Conditioning industry's history are being seen right now all around the world. Mainly driven by legislative regulations but also through the global drive towards a greener world, we see huge changes in technologies and refrigerants, within the group of players of the industry manufacturing Air Conditioning equipment and we see a change from trying to market a simple chiller or heat pump to offering a integrated, controlled, optimized and complete system for better Indoor Air Quality. In the future we will see systems which control any equipment or machine which has an influence on the heat – or cold – load of a building.
