Large hose is the low pressure hose.
LOW PRESSURE HOSE: Yes, a low pressure hose. A high pressure hose has a very small diameter opening since it is just used to measure pressure and it is not performing any work. A low pressure hose is used to perform work and has a larger diameter opening so air can move through it.
Normally a High Pressure hose will have bigger hydraulic fitting than the low pressure or "return". In fact if the low pressure hose has been serviced sometime it will just have a standard hose clamp on it.
Run the ac for awhile, the low pressure hose will be the cold one that is sweating.
