Propane (R290) can be used as a refrigerant and has significant advantages in environmental protection and thermodynamic performance.
Zero ozone depletion value (ODP=0): does not damage the ozone layer.
Extremely low global warming potential (GWP≈3) significantly reduces the greenhouse effect.
Low boiling point (-42.1℃): suitable for low-temperature refrigeration systems (such as refrigerators and freezers).
High energy efficiency ratio (COP value): Under the conditions of evaporation temperature -25℃ and condensation temperature 45℃, COP is better than common refrigerants such as R134a.
R290 is becoming a mainstream refrigerant. For example, air conditioner manufacturers have launched R290 air conditioners.
