The electric Air Conditioning (A/C) compressor is a 3-phase, variable speed scroll compressor. The electric A/C compressor is driven by a 3-phase Alternating Current (AC) electric motor. The electric A/C compressor incorporates a Direct Current (DC) to AC inverter to supply the 3-phase AC electric motor.
The electric A/C compressor circulates refrigerant around the A/C system by compressing low pressure, low temperature vapor from the A/C components in the A/C system. The electric A/C compressor then discharges the resultant high-pressure, high-temperature vapor to the A/C system.
To protect the A/C system from excessive pressure, a Pressure Relief Valve (PRV) is installed in the outlet side of the electric A/C compressor. The PRV vents excess pressure into the front compartment.
The displacement of the electric A/C compressor is altered by varying the electric motor speed, which is controlled by the HVAC control module. The HVAC controls the speed of the electric A/C compressor to match the thermal load of the A/C system and other factors.
The HVAC controls the operation of the electric A/C compressor through a Local Interconnect Network (LIN).
