    Just got me thinking how does the aircon engage then disengage? is it time based or temperature based?

    Temp based. Like all AC system when it reaches a detemined temp, system shuts off then turns back on if room/area temp goes a certain level.

    every two or so minutes disengage sya then mga 1 minute or more engage na sya ulet although minsan a few seconds bago mag 1 minute engage na sya ulet siguro mabilis lang uminit temp sa loob ng kotse ko wala kasing tint

    Increase mo na lang yung setting or the fan blower

    Minsan kasi naiinitan na tayo ayaw pa ilagay sa #2 yung fan.. keeping the fan at#1 will not save you gas and definitely will not prolong the life of your airconditioning unit

    The duty cycle of the a/c clutch is subjective with the following factors considered:
    Refrigerant pressure in the system,
    Ambient temperature,
    Cabin temperature,
    Coolant temperature,
    Control setting,
    Throttle position sensor signal,
    Sun load sensor signal,
    Engine rpm.



    There is no particular pattern unless your system is that of the old non-climate control system that relies on the a/c amplifier, or the pressure switch of the CCOT (cycling clutch orifice tube) type.


    Climate control is a more precise localized temperature targeting.
    In hybrids and electric cars, you dont have a compressor clutch and therefore you shouldnt be able to hear a clutch-like click on engagement
