Component Description
A/C unit assembly : Thermo Control Amp.
• Thermo control amp. is composed of thermistor and amplifier. Thermistor is installed on evaporator, and amplifier is attached to foot duct.
• When the thermistor detecting temperature of the evaporator fin is extremely low, thermo control amp. sends the thermo control amp. OFF signal to BCM, and stops the compressor.
A/C unit assembly : Blower Motor
• The blower motor utilizes a brush-less motor with a rotating magnet.
• Quietness is improved over previous motors where the brush was the point of contact and the coil rotated.
A/C unit assembly : Blower Fan Resistor
• Compact and lightweight resistor is adopted with outstanding ventilation.
• Temperature fuse is installed to protects the blower motor circuit.
A/C Control
Controls the air conditioning function.
BCM
BCM transmits A/C ON signal and blower fan ON signal to ECM via CAN communication, according to A/C switch signal and blower fan ON signal that are received from A/C control and thermo control amp. signal that is received from thermo control amp. and A/C indicator is turned ON.
ECM
ECM, when receiving A/C ON signal and blower fan ON signal from BCM, transmits A/C compressor request signal to IPDM E/R via CAN communication according to status of the engine and refrigerant pressure.
IPDM E/R
A/C relay is integrated in IPDM E/R. IPDM E/R operates A/C relay when A/C compressor request signal is received from ECM via CAN communication line.
Refrigerant Pressure Sensor
DESCRIPTION
• The refrigerant pressure sensor converts high-pressure side refrigerant pressure into voltage and outputs it to ECM.
• ECM operates cooling system protection and idle speed control according to voltage value that is input.
STRUCTURE AND OPERATION
• The refrigerant pressure sensor is a capacitance type sensor. It consists of a pressure detection ares and a signal processing area.
• The pressure detection area, which is a variable capacity condenser, changes internal static capacitance according to pressure force.
• The signal processing area detects the static capacitance of the pressure detection area, converts the static capacitance into a voltage value, and transmits the voltage value to ECM.
Magnet Clutch
Compressor is driven by the magnet clutch which is magnetized by electric power supply.
