The invention discloses a refrigerant composition capable of replacing HFC-134a, consisting of 2,3,3,3-tetrafluoropropene (HFO-1234yf), trans-1,3,3,3-tetrafluoropropene (HFO-1234ze (E)) and 1,1-difluoroethane (HFC-152a). The ozone depleting potential (ODP) value of the refrigerant composition is zero and the value of global warm potential (GWP) is extraordinary low, thus conforming to the requirement of environmental protection, and the refrigerant composition of the invention has the physical property equivalent to the physical property of HFC-134a, can be directly used for the existing HFC-134a system without redesigning a compressor.
Description
technical field [0001] The invention relates to a refrigerant composition, in particular to a refrigerant composition which can replace HFC-134a in existing refrigeration, air-conditioning or heat pump equipment using HFC-134a. Background technique [0002] Freons represented by HCFC-22, CFC-12, and CFC-11 have excellent thermodynamic cycle performance and are widely used in refrigeration, air conditioning and other industries. However, such substances have high ozone depletion potential (ODP), stay in the atmosphere for a long time, and have high global warming potential (GWP). They are one of the main chemical substances that destroy the atmospheric ozone layer and produce the greenhouse effect. After the ozone layer is destroyed, harmful ultraviolet radiation will directly reach the surface of the earth, causing serious damage to crops and phytoplankton in the ocean, and will also affect the human immune system, increasing the incidence of skin cancer and cataracts.
