Re-designed Automotive Climate Control Unit From Denso


Global automotive supplier Denso has developed a new automotive climate control unit that can be used for a wide variety of vehicles ranging from compact to luxury cars.

“Many of the subcomponents for this product, such as air mix door, servo motor and blower fan were newly developed to reduce the unit’s size by 20% compared to Denso’s conventional model, and significantly standardized the unit,” said Katsuhisa Shimokawa, executive director responsible for Denso’s Thermal Systems Business Unit.

The thickness of the air mix door is half that of Denso’s conventional ones, by using sophisticated forming technologies. The conventional unit required several servo motors to operate the air mix door, whereas the new unit has standardized doors and needs only one, enabling the unit case to be made smaller. For the new blower fan, the wing blades of the fan are re-shaped to best suit the wind flow, which allowed the new fan to become 15% smaller and consume 20% less power, yet maintaining high air discharge capacity.

With these new technologies, the new smaller, lighter climate control unit with higher performance can also be used in eco-friendly cars. For instance, for stop/start system the evaporator in the unit can be replaced with a cold storage evaporator, and for hybrid and electric vehicles the heater core can be replaced with a heat pump air conditioning system. Also by changing the blower fan to a two layer structure, o take in external air and circulate internal air simultaneously, the air conditioning system could be used for vehicles with limited heat sources.

Denso’s new climate control unit is used in the new HARRIER, which was released last December and in the NOAH and VOXY which was released this month. This new climate control unit will be offered for a wide variety of vehicle models all over the world.
