AIRCRAFT AIR CHILLER WITH REDUCED PROFILE

摘要

An improved aircraft air chiller unit particularly suited for an aircraft galley that requires refrigerated or cooled beverage/meal carts and/or chilled storage compartments. The chiller of the present invention takes the form of a line replaceable unit (“LRU”) and incorporates a liquid-cooled refrigerant vapor compression cycle, arranged in a housing with a vertical orientation. Because of the vertical orientation, ducting on the rear surface of the chiller is omitted, reducing the overall footprint.

主权项

1. A liquid-cooled, vertically oriented, line replaceable unit (LRU) chiller for cooling adjacent aircraft galley carts having a reduced footprint through omission of ducting along a peripheral surface, comprising:
a housing having at least one fan along an upper surface for drawing in air to the chiller unit through the upper surface and an opening in a bottom surface for expelling chilled air through the bottom of the housing; a pair of quick disconnect couplings for connecting with a condenser and an aircraft heat sink; an evaporator disposed directly below the at least one fan; a compressor; a heat exchanger; a liquid cooled condenser; an evaporator; and wherein warm air enters through an upper surface of the housing and chilled air is expelled through a bottom opening in the housing.
