Summary

A new refrigerant mixture THR02 based on CF3I was proposed as a new long-term and "drop-in" alternative to CFC-12 and HFC-134a. It has zero ODP, low GWP value (<50), non toxicity, non flammability, near-azeotropic and good thermal performance. The thermal parameters of THR02 such as the operating temperatures, pressures and volumetric capacity are very close to those of CFC-12 and HFC-134a. Therefore, THR02 can be applied directly to existing and new equipments as "drop-in" alternative. In this paper, the further evaluation results about reliability and thermal performance are discussed in detail. The miscibility of THR02 with MO, AB and POE oil is introduced. The material compatibility evaluations are presented. The composition change during refrigerant leakage out from cylinder has been tested. The thermal performance of domestic refrigerator using THR02 after two-years running is further discussed.
