Ice rink installations working with natural refrigerants NH3 and CO2.

Kunstijsbanen met NH3 en CO2, natuurlijker kan het niet.

Summary

In a growing number of countries it is no longer allowed to use large amounts of ammonia in areas occupied by many people. So new skating halls with direct ammonia systems are no longer being built, although these systems are the best solution in terms of ice quality and energy consumption. An indirect NH3/glycol or brine system uses about 20% more energy. By using (H)CFCs instead of ammonia, the energy consumption might be even higher. Over the past few years, CO2 has proven to be not only an excellent refrigerant but also a very suitable secondary refrigerant used to replace brines, etc. This article describes the successful application of a newly developed NH3/CO2 system to an existing ice rink.
