🥸 Learn about 🔥 Superheat ❄️ through this video!
✅ To determine the superheat at 155 psi for R410A, we need two things:
1. Saturation temperature of R410A at 155 psi.
2. Actual temperature of the refrigerant vapor (measured at the evaporator outlet or suction line).
Then: Superheat = Actual Temperature
Saturation Temperature
✅ Step 1: Saturation Temperature of R410A at 155 psi
Using an R410A pressure-temperature chart:
At 155 psi,
the saturation temperature is ~5°C
❓ Step 2: Actual Vapor Temperature
You need to measure this with a temperature probe on the suction line.
For example, if the measured temperature is:
15°C, then
Superheat = 15°C – 5°C = 10°C
8°C, then
Superheat = 8°C – 5°C = 3°C
🎯 Summary:
Suction Pressure Saturation Temp (°C) Superheat Formula
155 psi ~5°C
Superheat = Measured Temp – 5°C
