NOTE:
-
With this malfunction, evaporator may ice up although quantity of refrigerant in circuit is OK.
-
If expansion valve is malfunctioning (permanently closed or does not open sufficiently), A/C Compressor Regulator Valve N280 is actuated to
maximum output and low pressure drops to value in graph or below (compressor draws off refrigerant from low-pressure side). As however
refrigerant cannot flow via expansion valve, cooling output is not attained and high pressure may also not increase or only increase slightly due to
the absence of energy conversion.
