R410A refrigerant is a blended refrigerant composed of HFC substances, containing no ozone-depleting substances, with an ODP value of zero. Compared to R22, R410A significantly improves cooling capacity, making it possible to design smaller and more compact air conditioning equipment. Additionally, due to its near-azeotropic properties, the refrigerant temperature glide throughout the operating range is less than 0.2°C. R410A does not undergo significant separation in refrigeration and air conditioning systems, meaning the refrigerant composition does not change due to leakage. Therefore, during after-sales maintenance and replenishment, there is no need to discharge the remaining refrigerant in the system. R410A is globally recognized as the medium to long-term replacement for R22 refrigerant in household air conditioners.
