Carbon dioxide and CO2<\/a><\/strong> are very often the focus of discussions about the hole in the ozone layer as well as for other reasons. But maybe not everyone knows that CO2 is also an excellent gas that can substitute traditional gases employed as refrigerants<\/strong>, such as the classic freon<\/strong> which is correctly considered as a cause of the hole in the ozone layer.<\/p>\n

Recently, the sector of refrigeration<\/strong> has been intensely involved in the research of alternative gases in order to limit the greenhouse effect. An example is ammonia<\/strong>, that however has important negative side effects in terms of toxicity and flammability. The most recent born is then the CO2.<\/p>\n

There are in fact more and more cooling, refrigeration and conditioning plants<\/strong> on the market that are using CO2 in their thermal cycle, carbon dioxide. CO2 is a natural gas<\/strong>, with therefore a huge green aspect. But there are clearly also some complexities and implications, related to the fact that CO2 has state transitions are very high pressure levels<\/strong>, meaning 100, 120, 130 and up to 140 bars<\/strong>. And traditionally conceived refrigeration plants using freon work in the condensation phase at maximum pressure levels of 40-45 bars.<\/p>\n

It means that the overall components and equipments<\/strong> usually employed in refrigeration plants must undergo an important technological upgrade<\/a> in order to cope with CO2<\/strong> working conditions applications. There are in fact already functioning plants using CO2 on the market, and therefore the suitable equipments already exist too, although maybe not covering the full range of power capacities. There is for example a quite wide range of compressors available for CO2 applications<\/strong>, even if not in all the sizes and power capacities.<\/p>\n
