So I hooked up the gauges today and took some readings while the AC was running.
Conditions:
- Vehicle parked under full shade (in open but covered garage)
- Full cabin fan speed
- Air on recirc (inside air), couldn't do it on outside air since fan was throwing out 60c air and was going to mess up all readings.
- Only at fast idle (~900rpm): I remember low side being higher, around 60-ish (didn't take exact readings). Rest of readings at 1500rpm
Readings:
- When fans ran at half speed: 40 (low), 225 (high)
- When high speed fans kicked in: 38 (low), 210 (high)
- Outside (ambient) temperature: 35c
- Inside vent air temperature: 20.5c
Couldn't take readings for subcooling/superheat because radiator's hot air was messing things up. So till I get an insulated thermocouple, It will have to wait.
- Plus I do hear a faint hissing noise throughout the time aircon is ON, from behind the glovebox.
So whats the opinion here? I have some thoughts but I want your opinions without my thoughts clouding them.
Edit: tagging @xulfiqar so he wouldn't miss this. I know you busy.
