Yes. If we want to turn the AC on the car, do it at low RPM. RPM position (or rotation per minute) at low engine idle there, when we did not step on the gas pedal. Steps like these we need to do if we want to take care of air conditioning. The technical reason is actually very simple steps. That is, in order to avoid friction between the pulley and the overly harsh pressure plate (pressure plate) on the AC compressor. Pulley and pressure plate is a very important component in the air conditioning system work. Pressure plate is the component that serves as a liaison so that the air conditioning compressor shaft to rotate. Duties as a liaison was only able to run after the pressure plate attached to the pulley. Pressure plate will be close (to adhere) to the pulley when we turn on the air conditioner.
The problem, pulley is always spinning components for engine life. And, pulley rotation is changing. Sometimes fast, sometimes slow. High and low pulley hanging round the engine. Pulley will turn faster when the engine per minute (RPM) high. Conversely, slower when low rpm per minute. Of work that we can predict, when it is appropriate to attach the pressure plate to the pulley. And we can imagine what would happen if we put a pressure plate when the spins very fast. On lap faster, the friction between the surface of the pressure plate and pulley will be very hard. If this practice continues to happen, the two components of friction surfaces will quickly wear out. When already worn out, the next effect is tedious: rotary power engine to its full potential can not be forwarded to the AC compressor. Engineers call this condition the term slip.
There are two effects that are generally advanced riders feel if slip occurs. First, the AC was not cold enough. Second, there was a noise on the AC compressor. The impact that makes us uncomfortable, is not it? Therefore, if you want to turn on the air conditioner, do it at low RPM.
