Table 1: Pressure Temperature of R600a vs R143a and R290 vs R404A
- A given displacement compressor with R600a will produce 50 to 60% of the capacity that it would with R134a. R290 will produce 85 to 90% compared to R404A.
- Table 2 shows the comparison of some properties of R600a, R134a, R290, and R404A. The data is taken at the standard refrigerant conditions of 5°F (-15°C) evaporating and 86°F (+30°C) condensing.
