Over the years numerous novel solutions have been developed using state-of-the-art. natural refrigerants. Beside traditional ammonia applications, the safe and efficient use of carbon dioxide and hydrocarbons has become common practice and even water is set to become a commercial refrigerant. There have also been advances in indirect cooling.
Things have also been moving fast in Denmark. In 2001, a severe prohibitive tax was introduced for HFC, and an actual ban from using HFC in new large equipment will take effect as from 1st January 2007 - with few exceptions. Consequently, not only are new refrigeration solutions being developed using natural refrigerants, but also low emission HFC systems with refrigerant charges below 10 kg are being looked at. In 2006 more than 100 commercial and industrial plants were built using CO2, hydrocarbons or water as refrigerant. Other types of refrigeration systems such as sorption, absorption and adiabatic cooling are also being employed. By 2008 the number of refrigerating systems using alternative refrigerants will have increased exponentially. This is also likely to be the case for the new methods of refrigeration which will by then have been conceived. By joining the conference you will benefit from this wealth of experience.
