19.8. Diagnostics of malfunctions

19.8.1. Check of system of cooling of air

GENERAL INFORMATION

In the presence of signs of malfunction of system of cooling:

1) To check external surfaces and a radiator and the condenser, to be convinced of lack of contaminations (dirt, leaves, etc.) and in possibility of free movement of air through honeycombs of heat exchangers. To examine also space between a radiator and the condenser.

2) To check, whether there are no deformed and pressed tubes in the heat exchanger, hoses, pipelines, etc.

3) To check serviceability of the fan.

4) To check all air lines on existence of thinnesses or contaminations. The low consumption of air can indicate capacity reduction of the heat exchanger of the evaporator.

5) To check existence of pro-slipping of coupling of the compressor.

6) To check a tension of a driving belt of the compressor.

7) At existence in KB system of the V-5 compressor to carry out control checks.

Possible malfunctions and methods of their elimination (KB system with coolant R-12)
SIGNS REASON ELIMINATION
At inclusion of a signaling device of a high pressure the compressor stops The steam valve of a tank is closed To open the valve
The tank is completely filled with a coolant To remove and replace a tank
To check calibration of a weight platform or to consult with factory experts
The compressor continues to work after achievement of a razryazheniye of 432 mm Hg (57,5 kPas) The vacuum switch is faulty To replace the switch
The compressor turns on, but does not work Compressor overheat To cool the compressor

The compressor is faulty To replace the compressor to Add 90-120 ml of refrigerating oil of brand 150 in an absorption cavity at the working compressor
There is not enough oil in the compressor
The spot in the center of the indicator of humidity does not change the color with yellow on green (after work within two hours) Moistening of the filter of a dehumidifier To remove and replace the dehumidifier filter
Insufficient quantity of a coolant To add a coolant to norm in a tank
Decolouration of the indicator of humidity To remove and replace the indicator
The compressor does not provide razryazheniye level in system of 432 mm Hg (57,5 kPas)
There is not enough oil in the compressor
To add 90-120 ml of refrigerating oil of brand 150 in an absorption cavity at the working compressor
Leaks in system To eliminate leaks
The compressor is faulty To replace the compressor
There is no coolant movement
The liquid valve of a tank is closed To open the valve in system contours in a mode
The steam valve of a tank is closed To open the retsirkulyatsiya valve
The pump is disconnected To switch off and again to turn on the pump

The coolant pump is faulty

To remove and replace the pump
