To provide an improved air chiller device to be mounted on an aircraft for feeding cooled air in serving meal supply.

The air chiller device comprises a refrigerating cycle unit mounted on a casing. The refrigerating cycle unit consists of a refrigerant compressor, a condenser, and an evaporator. Cooled air is fed to a galley or others via a blower device 60. A housing 630 of the blower device 60 has a cold air inlet and two air outlets 650, 652. A duct member is inserted into one of the two air outlets 650, 652, and the other air outlet is sealed. The casing 10 is formed of a honeycomb panel. The honeycomb panel has high bending rigidity and so the refrigerating cycle unit can be supported only by a base plate. It also has heat insulating property to improve the efficiency of cooling air.
