Climate Control Systems (IHKR/IHKA)
Two climate control systems are offered on the X5, the manual IHKR system is standard equipment on the 3 liter X5 and the IHKA system is available as an option. The IHKR is a
new system for US production and the IHKA is taken from the E39 vehicles.
The X5 incorporates a new design air conditioning condenser/receiver dryer for both the manual (IHKR) and the automatic (IHKA) systems. The dryer cartridge and condenser are one component with the dryer integrated on the left side. The dryer cartridge contains a replaceable filter screen and dryer unit.
The condenser is partitioned which divides the condenser into cooling sections. The hot refrigerant flows across the condenser and into the dryer through inlet holes at the lower 1/3 section of the cooling fins. After the refrigerant passes through the dryer it returns to the evaporator through the outlet hole and bottom 1/3 section of the condenser.
