CO2 technology and Winter Sport Venues: a perfect matching -G. Pisano-
Winter sport venues are very popular in many Countries worldwide. Efficient refrigeration systems are at the heart of such sites as they typically feature large energy draws. Another key driver is connected to comfort and safety of the large amount of people typically gathering thereby. CO2 is non toxic and non flammable so it can be considered as a very good refrigerant for such applications. However, its main limiters were the unavailability of large trans-critical compressors needed to cost efficiently cope with the large duties normally involved as well as possible efficiency penalties for those systems operating all year around, e.g. during warmer seasons. However, with the usual strong focus on market requests, DORIN has once again shaped the future and recently developed and launched the largest CO2 trans-critical compressors range, with displacements up to 60 m3/h and 100 hp electric motor size: this made it possible to cost-effectively introduce CO2 trans-cr...
