Vehicle A/c System--

                                  vehicle A/c system uses only 2 purpose, 1)Journey is comfortable, and the second thing is 2)Humanity control,
        Many people told when A/c on a car continuous dropping water outside from the vehicle and home made refrigerator don't dropping water outside , this is a simply reason 

                         "Vehicle A/c control the interior humanity,  home made refrigerators don't do that🙂

Vehicle A/c system's have a many component depend on types may be "Manual" or "Automatic

Components are-Compressor,Condenser,Evaporetor, Expansion valve,Low ,Suction, Discharge,and High pressure pipe Lines etc

      Automatic A/c systems have a extra component like Amplifiers

      All component have a specific role

• compressor
• condensor
• expantion valve
• evaporator unit
• pipelines
• fan motor
  
  
  

Compressor

Its working principle is low pressure low tempareture refrigarent convert to high pressure high temperature refrigarent modern AC have a two different system one is magnetic clutch and another one is without magnetic clutch or clutchless compressor, magnetic clutch system have only Thermister sensor pressure switch and amplifier but clutchless compressor have a more Electrical system are inbuilt,like flow sensor,sonar sensor, engine rpm optimization, accelerator padel position,ambient temperature sensor, interrir tempareture sensor and these part are control by amplifier which are control through Engine ECM,compressor fitted on two pipes one are return pipe which are fitted from evaporator or cooling coil to compressor and another one is discharged hose which are compressor to condenser.

Condenser 

It's working principle is high pressure high tempareture refrigarent convert to low pressure low tempareture refrigarent through atmospheric air because their have small fins for enhance cooling and better cooling performance,if this is closed through dirty particles then this is clean through low pressure compressor air first and next low pressure water gun used for clean totally,because some time AC not cooling properly is this reason.

Evaporetor /cooling coil

Cooling coil is enter in evaporator unit and blower fan touch this part to out a cool air in car interrir compartment,cooling coil have a fins and sliding line and this parts are cold almost 2 degree Celsius because this is vary the target tempareture and actual tempareture,this cooling coil when leaked and that time AC gas are totally leakage and this cooling coil are check through nitrogen because nitrogen does not enter any moister in this system

Expansion valve
Its working principle is controlling the refrigarent quantityfrom evaporator unit based on interrior humanity; its controoled by a/c pressure switch & ambient tempareture sensor

pipelines 

Those part are connected to some pipelines its have a different name ;compressor to condensor are connected to discharge hose;condenser to expantion valve are connected to high pressor pipelines;expantion vaalve to compressor are connected to low pressor pipe/lequid hose/suction hose 

Cooling Fan

Its run in two way one is when a/c is on either when /c coolant tempareture is high,fan motor are connected through relay and fuse this relay activate two times first when ac on and another when ac off but car coolant temperature care above 90 degree Celsius and thermostat swich open,if fan motor are not rotate at AC on condition then AC not cooling properly,that time you check the fan motor fuse and relay also

Pressure switch

It is component of pressure switch which sense the refrigarent pressure and sense pressure send to the AC Amplifier for compressur magnetic clutch on /off,if this pressure switch damaged or these wiring cut so AC compressur magnetic clutch not work and compressor are totally off

AC Fan motor

AC fan motor that is a part of vehicle AC system when ac fan motor are not working when ac switch on then AC not cooling sufficient these fan motor have a fuse these are basically some time blowing and some time fan motor damaged this why when ac on but interrir tempareture not cool down

  Vehicle refrigarent Name is             r134a   When A/C system leakage need to enter the system is UV oil (that's like a green colour)             Homemade  refrigarent Name is.  r12
