As an option, it is possible to have additional air conditioning in the rear of the seven seat XC90. The air conditioning unit is located inside the panel on the left hand side of the cargo compartment panels. The front and rear air conditioning refrigerant circuits are connected in parallel. The rear air conditioning is connected via a connector on the firewall.
The connection between the rear and front air conditioning units is via pipes and rubber hoses inside the passenger compartment. The fan (1) is operated using a control (5) placed on a panel at the rear of the passenger compartment.
The compressor, condenser and receiver drier are used together by the front and rear air conditioning units.
A T-connection is located on the high-pressure side in the engine compartment between the receiver drier and the expansion valve. A T-connection for refrigerant, with high pressure, from the front climate control unit to the rear climate control unit.
The refrigerant is sprayed into the rear evaporator using the rear expansion valve. Then the refrigerant is routed at low pressure back to the front air conditioning unit. The return routing is connected to the front cooling system using a T-connection located between the expansion valve and the compressor on the low pressure side of the engine compartment.
