A mixture alternative refrigerant to HCFC-22 named THR03 was developed by us.The calculation results of THR03 was compared with HCFC-22 and other alternatives. The standard A/C performance test for THR03 and HCFC-22 in the same air conditioner was done. The flammability and the material compatibility test are also discussed in this paper. It shows that THR03 has zero ODP, low GWP value, non toxicity, non flammability, and good thermal performance. The thermal parameters of THR03 such as the operating temperatures,pressures and volumetric capacity are close to those of HCFC-22. Therefore, THR03 can be applied directly to existing and new air conditioner as “drop-in” alternative.
