LEARNING OBJECTIVES:Training participants can check and repair the disruption in car air conditioning systems are noticeably less or no cold, with mediagnosa through visual signs on a series of mechanical and electrical circuit AC carB. EQUIPMENT:1. The special manometer for sisten AC2. The special charging equipment air conditioning systems3. The leak detector refrijeran4. Thermometer5. Glasses6. Gloves7. Box toolC. MATERIALS:1. Car stand with AC motors2. Refrijeran R-12D. SAFETY:1. Always use gloves and goggles when working with refrijeran.E. STEP WORK:For diagnosing and solving interference on AC systems with less or no cold, start doing diagnosis in general as "Flow Chart" (the scheme) is, before carrying out diagnostic functions of partsVISUALGeneral condition of the system• Control the condition of the pipe installation possibilities: loose, not clamped properly, cracked, broken etc.• Control the condition of the electrical installation, plug / cable connection is bad / corrosion etc.• The compressor and the surrounding• Hold the hand suction channel (S) and drain tap (D) compressor to sense temperature.Symptoms / signs Cause- Channel compressor suction and body temperature is low, condensation water becomes much around the suction channel and the compressor body - Valve is always open full expansion, because it does not stick well control pipe at the outlet of the evaporator- Evaporator dirty- Channel press (D) and the compressor body hot, water condensation on the suction channel (S) very little / hardly any - opening the expansion valve bit / covered with ice due to the filter saturation / old.- Errors condenser or fill too full refrijeran- Channel D and compressor body unidirectional channel D, not too hot. Channel S is no condensation of water and the direction of the channel S compressor body feels a bit cold - condition parts of the normal AC systemCondenser• Dirt on condenser Check and clean the condenser• The temperature of the condenserSymptoms / signs Cause- At the outlet of the condenser is hot (> 40C) - There is dirt on the grid / fin condenser- Cooling condenser is not enough, check the direction of rotation of the cooling fan- The condenser is too small- Condenser pressed with radiatorPart sieve filter• Check the condition of the contents of the system through a glass refrijeran controllerSymptoms / signs Cause- There is always a foam / bubble refrijeran time the air conditioning worked, and the symptoms disappeared some time after the AC is turned off - Fill refrijeran less- No foam refrijeran time and switched off the air conditioning worked - Fill refrijeran no or too full- There is a foam / bubble refrijeran time AC started working, and the symptoms disappear when the motor rotation has been raised - enough refrijeran Content• Temperature filterSymptoms / signs Cause- Inlet, outlet and filter body feels hot - Errors in the condenser- Inlet feels a bit hot, and cold filter out sa¬luran ge¬jala usually is followed by no foam / gelem¬bung refrijeran on the glass filter control despite increased motor rotation - already saturated Filter / oldEvaporator parts & accessories• condensation-water discharge hose conditions should be attached either / not leaking and the water must be flushed out vehicle• Check the blower motor work in each round.• If the vehicle's air conditioning system using the original check all conditions pengon¬trol switch the direction of air flow blower motor, as an example:A. The main switch ACB. The selector switch air flow directionC. The temperature switch (thermostat)D. The switch ventilationE. blower motor speed switchPosition switch B1. Air flow towards the face of the passenger2. The air flows in the direction of the face and foot passenger / floor3. The air flow
