It's the compressor clutch - it's electromagnetically operated so is either on or off, perfectly normal behaviour. It also shows the system is cycling on and off regularly which suggests it has enough gas in it, if it was low on gas (or you selected an extra low temperature) the clutch would remain engaged until the desired temperature was reached and then disengage.
