geometry air conditioning compressor; that is, the
compressor adapts the flow of refrigerant fluid
according to a difference in pressure between the
compressor inlet and outlet, and not according to the
temperature read by the sensor (omission of the
evaporator sensor).
The system cannot be adjusted
The pressure relief valve is still present but calibrated
differently.
