Résumé

HFO-1234yf has been identified as a new low global warming refrigerant which has the potential to be a sustainable solution for automotive air conditioning and potentially for stationary systems. HFO-1234yf is a pure compound which is energy efficient, exhibits low toxicity in testing to date, and can potentially be used in systems currently designed for HFC-134a with minimal modifications. Life cycle climate performance (LCCP) calculations also indicate a significant environmental benefit versus HFC-134a, HFC-152a and carbon dioxide in automotive air conditioning. Although HFO-1234yf is mildly flammable per ASTM E681-2004, it is significantly less so than HFC-152a and HFC-32 and has the potential to be used in direct expansion systems without a secondary loop.
