Description

It is a heat pump system that exchanges low-temperature refrigerant by using waste heat from the high voltage battery.

Removal

   

• When working on high voltage system, the work should be performed by technicians who have completed the relevant training. A lack of understanding of the high voltage system can lead to serious accidents due to electric shock or electric leakage.

• When working a high voltage system, the technician must be observed and aware of "High Voltage System General Safety Information and Caution". If not, it may cause serious accidents such as electric shock or short circuit.

• When working on high voltage system, make sure to check the Personal Protective Equipment (PPE) and high voltage shut-off procedures.

1.Disconnect the battery negative ( - ) terminal and the service interlock connector.(Refer to Battery Control System - "Auxiliary 12 V Battery - 2WD")(Refer to Battery Control System - "Auxiliary 12 V Battery - 4WD")

2.Recover the refrigerant with recovery/recycling/charging equipment.(Refer to Air Conditioning - "Refrigerant Recovery/Recycling/Charging/Evacuation")

3.Drain the coolant.(Refer to Electric Vehicle Cooling System - "Coolant")

4.Remove the front trunk.(Refer to Body - "Front Trunk")

5.Disconnect the chiller hose (A).

6.Remove the chiller inlet line (A) and chiller outlet line (B) after removing the bolts.

Tightening torque :8.8 - 13.7 N·m (0.9 - 1.4 kgf·m, 6.5 - 10.1 lb·ft)

   

When disconnecting a line, immediately put on a plug or cap to protect the system from moisture and dust.

7.Remove the chiller (A) after removing the bolts.

Tightening torque :7.8 - 11.8 N·m (0.8 - 1.2 kgf·m, 5.8 - 8.7 lb·ft)

Installation

   

• When working on high voltage system, the work should be performed by technicians who have completed the relevant training. A lack of understanding of the high voltage system can lead to serious accidents due to electric shock or electric leakage.

• When working a high voltage system, the technician must be observed and aware of "High Voltage System General Safety Information and Caution". If not, it may cause serious accidents such as electric shock or short circuit.

• When working on high voltage system, make sure to check the Personal Protective Equipment (PPE) and high voltage shut-off procedures.

1.Install in reverse order of removal.

   

Be sure to inject the specified refrigerant (R-1234yf) and refrigeration oil (POE) by using the refrigerant recovery/charging equipment dedicated to the electric compressor. Compressor damage and safety accidents may occur if refrigeration oil (PAG) of general vehicles is mixed.

   

• When installing a single unit, install it with the specified torque.

• Check for refrigerant leaks by using a gas leak detector.

• Charge the refrigerant after removing the air in the cooling system.
