Carbon dioxide (CO2) has nowadays become the standard refrigerant choice for many applications, often granting better COP levels than the previously adopted HFC technology: this trend is progressively leading to both a lower usage of high GWP refrigerants and a sensible Energy cost reduction for several industrial sectors.
Considering thermal and fluid dynamic properties of CO2 it is clear that it is necessary to introduce advanced solutions in the refrigerating circuit, compared to a standard HFC's system. Talking about the compressor, the most stressed element of the system, it was crucial to introduce some advanced design solutions, most of them coming from other highly technically advanced industrial sectors, such as automotive.
DORIN, undiscussed global leader in CO2 technology and production of compressors, started from the very beginning to design a new type of compressor completely focused on CO2.
