Refrigerant options in stationary AC&R systems.

Auteurs : ACHAICHIA N., MATTEO G.

Résumé

As a result of the need to find suitable substitutes for higher global warming refrigerants, two new low global warming refrigerant molecules were identified, HFO-1234yf and HFO-1234ze. These molecules are hydro-fluoro-olefins (HFO) that have very short atmospheric life times of 11 and 18 days (as compared to 12 years for R134a) and have extremely low GWP of only 4 to 6 (as compared to 1410 for R134a). In addition to these two single component refrigerants, low global warming refrigerant blends that have properties closer to existing higher pressure refrigerants such as R404A, R407C, and R410A have been developed. This paper discusses properties and applications of these potential refrigerant options in stationary AC&R systems.
