Carbon dioxide (R744) is a natural refrigerant (with a global warming potential of 1 and potential thinning of the ozone layer of 0), with very good thermodynamic properties. However, is rarely used as a refrigerant because of the very high pressure that it works with and the low temperature critical point.<\/p>\n
As such, the use of refrigeration systems based on carbon dioxide requires a level of automation<\/a> superior to other types of refrigeration systems<\/a>, as well as materials resistant to very high pressures (up to 110 bar for applications in the trans-critical field).<\/p>\n Carbon dioxide is used as a refrigerant for the lower stage of a cascade refrigeration system, as an intermediate refrigerant, with a phase exchange (vapor \/ liquid) or trans-critical systems: heat pumps, industrial applications or air conditioning systems for cars.<\/p>\n The first refrigeration systems in Romania based on carbon dioxide was carried out by our specialists in 2009.<\/strong> Carbon dioxide (R744) is a natural refrigerant (with a global warming potential of 1 and potential thinning of the ozone layer of 0), with very good thermodynamic properties.

\nThis refrigeration system is a heat pump that works in the trans-critical field to a maximum operating pressure of approximately 100 bar. After exiting the heat pump, the water temperature is 75 \u2013 85\u00ba C.<\/p>\n","protected":false},"excerpt":{"rendered":"
