At serviceable system of cooling of air the entrance branch pipe of the evaporator and a receiver surface should have identical temperature, which on some degrees below air temperature. To check up presence of other malfunctions. To check up presence of leaks of a coolant. At detection of leaks to discharge system KB and to make necessary repair. Then again to charge systems KB a coolant. If leaks it is not revealed, to spend detailed check of system SQ. |
