Elements of the air conditioning system

1 – tube (And);
2 – a tube (In);
3 – final tube;
4 – final tube;
5 – port from high pressure;
6 – evaporator block;
7 – tube;
8 – nut, 5–7 N • m;

PERFORMANCE ORDER
1. Install the manometer to the highway.
2. Start the engine, leave to work at the frequency of rotation of bent shaft 2000 mines-1 and set the mode of the maximum cooling with a high frequency of rotation of the fan.
3. Open all windows or doors.
4. Install the thermometer in an air supply lattice in interior of the car.
5. Install damp and dry thermometers as it is possible closer to an entrance opening of the block of cooling.
6. Check that pressure shown by the manometer is in limits of 1,373-1,575 kPa. If pressure too high, pour water on the condenser. If pressure too low, close the forward party of the condenser.
7. Check that air temperature in an air supply lattice in interior of the car is in limits of 25-35 °C.
8. According to the schedule calculate relative humidity of air, comparing temperature of damp and dry thermometers.
9. Take temperature in an air supply lattice in interior of the car and calculate a difference the dry thermometer and the thermometer in an air supply lattice.
10. Check that if crossing of relative humidity and a difference of temperatures are in admission limits, so the air conditioning system works normally.
