Firstly the compressor cycle depends upon the temperature of the evaporator. At a specific temperature at evaporator (Don't remember exact), the compressor will be switched off. The other thing is if you turn on fan blower at lower speed, the compressor will cycle quickly as the evaporator temperature will be quickly reaching the threshold. If you run fan blower at 4, the compressor will run mostly all the time as the evaporator temperature will not be reaching the threshold.
Simply concept is if more air blows through the evaporator, the temperature at the evaporator will drop slowly or may not even drop.
Secondly the bottle should have pressure sensor which in my car is also missing. So we can assume that this wasn't given by Honda Pakistan like power steering pressure switch is also not given in our car.
