Fast check of serviceability of functioning of central air of air

Fast check of serviceability of functioning of central air of air (on an example of the minibus of a series 901, - check is made for M-class models in a similar manner)

1 — a temperature Measuring instrument
2 — the Observation port of a receiver dehumidifier

3 — the Detector of leakages of a coolant


 PERFORMANCE ORDER

  1. The illustrative material on fast check of serviceability of functioning of central air of air is presented on an illustration which all references meeting in the text concern.
  2. Tire out the car in a shadow, open all windows.
  3. Transfer the handle of a choice of a temperature mode to the situation COLD (Cold).
  4. Include a mode of supply of fresh air.
  5. Completely open sections through passage snuffled all air lines.
  6. Start the engine on single turns.
  7. Include To/in, - turns of the engine should increase.
  8. Include the maximum high-speed mode of functioning of the fan.
  9. Through an observation port of a receiver dehumidifier (2) make sure of lack of signs of a puzyreniye of a coolant.

At primary start of svezhezapravlenny system formation of air bubbles should not cause concern, - wait about 10 minutes, - bubbles should disappear.

  1. Attentively study an external condition of all components refrigerator To/in, by means of the special detector check them on existence of signs of development of leaks.
  2. Transfer the fan to a high-speed mode "1" and by means of a special measuring instrument (1) measure temperature leaving via the central deflectors of the dashboard of air. 5 minutes of functioning of system later the temperature of air submitted to salon should be in range limits +2°С ÷ +12°С, and the To/in compressor should pass to a cyclic mode (in, otherwise it is necessary to check a condition of the sensor switch of temperature of the evaporator.
  3. Switch off the conditioner and muffle the engine, - more detailed checks of To/in system should be carried out in the conditions of a car-care center workshop.
