THR03 Alternative Replace to HCFC-22 and R502

1. Environmental Characters of THR03

From the charts, the ODP of THR03 is zero, GWP is much lower than that of HCFC-22 and R502 with better environmental characters. So it is a long term alternative replace to HCFC-22 and R502.

2. Safe Characters of THR03
THR03 is non toxicity owing to a physical mixture of three non toxicity matter. It is nonflammable after test and calculation.

3.Thermal Performance of THR03
The following charts show the thermal performance of THR03 replace to HCFC-22 under air-condition conditioning and THR03 replace to R502 under low temperature refrigerations.

(b)AUTOMOBILE AIR-CONDITIONING

From the charts, the COP of THR03 is smaller than HCFC-22 under air-conditon terms, capacity refrigeration and can use the compressor of former system.
The Thermodynamies lab of Tsinghua University and Chunlan Co, tested the thermal performance of air-conditioning used THR03, proved that the thermal performance of THR03 and HCFC-22 is similar.

4.Drop-in Effect of THR03

Research Institute of China Petroleum Processing tested the miscibility of THR03 and ester oil, proved that they are miscible. THR03 is compatible with material of HCFC-22 and R502 system too after the examination of material compatibility according to international standard.
The THR03 replace to HCFC-22 and R502 no need to change the major parts and the former production line, only change the oil as ester oil to drop-in.
