Evaporator Icing up may be what's causing your particular problem, but another issue I and many others had was a poorly designed A/C compressor over-temp sensor. the reason I say poorly designed is because Volvo took it out of the circuit on later units and advised dealers to wire around it when a customer complains. It didn't seem to hurt the compressor to wire around it.

The compressor would work fine on first use and then at some point the sensor would trip the power to the clutch and the compressor would not engage. Wait some period of time (1/2 hr or longer) and it would kick back in again.

If it is indeed an evaporator icing problem you might be a little low on refrigerant (R-134a).
