• The computer provides commands to the robot to begin out pressurizing the refrigerant along with the combination door actuators to direct air result the bottom, middle and unfreeze vents. It collectively controls blower fan speed. Actuators collectively management air temperature by change of integrity the new air from the heater and thus the cold air from the A/C.


• Let's begin with the refrigerant (r134a) within the system. This specific refrigerant was specifically created for the automotive business someday within the late 1980’s that is slightly totally different than home or industrial refrigerant applications.

• This half fluid, half gas is command struggling within the system. once the system isn't running the refrigerant remains a gas underneath low, regarding seventy psi. The optimum property of this gas is its ability to travel from a hot gas once it's compressed (250 psi at regarding 180° F or 82° C), associate degreed once cooled within the condenser settled ahead of the radiator it transforms into a heat aggressive liquid that is then is free through an growth valve or passage tube (small hole). The aggressive liquid instantly transforms to a unaggressive gas vapor (35 psi at 32° F or 0° C) that creates the coldness within the evaporator during which case the blower motor passes air through it and into the ventilation and into the inside of the automobile.


• The AC system has four basic parts: A mechanical device, that is hopped-up by the engine victimization the curved belt and incorporates a low facet port that's connected to the evaporator {along with along facet|in conjunction with|beside|at the side of| together with} a air mass side port that is connected to the condenser victimization rubber hoses. The mechanical device is that the main mechanical a part of the system with internal workings that has got to be lubricated by peg oil (synthetic).
