USES:

Can replace R22.

R424A

Advantage: 1. The pressure of work and R22 basically the same (slightly lower)

2. The temperature glide small (3 degrees), reveal that below 60% do not need to inject

3. The COP value is higher than R22 about 3% - 5%

4. Unique oil return technology can be very good with mineral oil

5. The exhaust gas temperature is lower than R22, long-term stability makes the system work

R424A compared with R22 physical properties
