SYSTEM HAC-35 < SYSTEM DESCRIPTION > [AUTO A/C (WITH HEAT PUMP)] C D E F G H J K L M A B HAC N O P • When intake air temperature sensor detects that air temperature after passing through evaporator is 1 °C or less, A/C auto amp. sends a request to the electric compressor for a speed of 0 rpm, stopping compressor operation. • When the air temperature after passing through evaporator reaches 4 °C or more, operation of the electric compressor is resumed. Compressor Protection Control at Pressure Malfunction • When the refrigerant pressure on the high-pressure side (detected by the refrigerant pressure sensor) that is received from the VCM via EV system CAN communication is as shown below, the A/C auto amp. stops the compressor. - Approximately 2.65 MPa (Approximately 27.0 kg/cm 2 ) or more - Approximately 0.14 MPa (Approximately 1.4 kg/cm 2 ) or less • When the refrigerant pressure on the high-pressure side returns to the range below, the A/C auto amp. resumes operation of the electric compressor. - Approximately 1.55 MPa (Approximately 15.8 kg/cm 2 ) or less - Approximately 0.16 MPa (Approximately 1.6 kg/cm 2 ) or more AUTOMATIC AIR CONDITIONING SYSTEM : Door Control INFOID:0000000010121758 SWITCH AND THEIR CONTROL FUNCTION JSIIA1650GB Intake door Blower motor Air conditioner filter Evaporator Upper air mix door Lower air mix door JMIIA2747ZZ |
