is the ac compressor supposed to cycle on and off

The air conditioner in your auto works in almost the same way that the i in your home does. The difference is only in the controls—only very new or luxury vehicles have a thermostat with a temperature-like home system. Even if your automobile does have this feature, the system works the aforementioned way to make the machine cool. The control panel is just a little fancier.

An air conditioner works by compressing a chemical refrigerant to forcefulness it to go from a gas to a liquid. When the refrigerant changes state, from a liquid into gas, heat is transferred. Air that is leap for the cabin will laissez passer over the evaporator. In effect, the heat is taken out of the air and put into the refrigerant. Yous can't really "create" cold air, so instead, you lot movement the rut from your cabin air into the refrigerant. The now-hot refrigerant is trapped in a closed circuit, and it gets taken outside to where the compressor again compresses the gas back into a liquid, and the cycle starts once again. At this indicate, the refrigerant creates heat, but information technology'south outside the motel of the machine.

Information technology's the temperature of the evaporator that makes the air cold, not the compressor itself. Equally long every bit the evaporator gets cold and has air flowing over it, the cabin will cool down.

There are iii other important parts of your car's ac system you should understand. The commencement is the fan, which blows air over the evaporator and through the ducts. It's not connected to the compressor, so the fan can blow outside air, the air warmed by the heater, or air-cooled by the evaporator.

The second control to understand is the recirculate button. This pulls air only from the within of the car. It'due south an important part of the organization considering the air conditioner can only cool down a given book of air and then much. If the air information technology'south trying to cool is continuously coming from the outside, it volition never get very far. The recirculate button allows it to use the air it'south already started to cool down from inside the car's motel. It will get cooler and cooler the more times it's recirculated.

And finally, there is the mixture control, which mixes hot or common cold air. You can utilize it to arrange the airflow between the heater and the air conditioner. If the air conditioner air is as well cold, you can mellow it out a bit.

So, to become maximum ac in your car, you need the fan on total, the recirculate push on, the mixture control to cold, and the air conditioner compressor on.

The air conditioner compressor, which usually has its button on the panel, volition cycle on and off as necessary to produce the maximum amount of hot air. Like any other slice of equipment in your car, it has a duty bike and temperature limits that it is designed to not exceed.

The system cannot allow the cooling coils to freeze up, and it cannot permit the compressor to overheat. To accomplish this, the compressor will cycle on and off at regular intervals. So long as cold air is blowing out of the vents, there is nothing to worry about. If it's cycling rapidly or doesn't blow any cold air at all, information technology's fourth dimension to see your mechanic for a check-up.
