Chiller galley cart, galley, and method for cooling

A galley comprising:

• a cart compartment configured to store a plurality of galley carts including a chiller galley cart and at least one demand galley cart, the chiller galley cart including a plurality of walls defining an interior cavity and a chiller positioned in the interior cavity, the chiller including a heat exchange unit and an air circulator to provide cooled airflow from the chiller galley cart, the chiller galley cart including a supply valve in flow communication with the chiller and a return valve in flow communication with the chiller, wherein the heat exchange unit of the chiller comprises an evaporator, a compressor, a condenser and an expansion valve positioned in the interior cavity and is coupled in flow communication to the supply valve and the return valve to provide the cooled airflow from the chiller galley cart;
• a supply duct configured to be in flow communication with the plurality of galley carts;
• a return duct configured to be in flow communication with the plurality of galley carts;
• a chiller supply port in flow communication with the supply duct, the chiller supply port coupled to the supply valve of the chiller galley cart of the plurality of galley carts to channel cooled air from the chiller positioned in the chiller galley cart into the supply duct;
• and
• a chiller return port in flow communication with the return duct, the chiller return port coupled to the return valve of the chiller galley cart to channel return air from the return duct into the chiller positioned in the chiller galley cart.

A method for cooling at least one demand galley cart positioned in a cart compartment of a galley, the galley including a supply duct, a return duct, a supply port in flow communication with the supply duct, and a return port in flow communication with the return duct, the method comprising:

• positioning a chiller galley cart in the cart compartment, the chiller galley cart including a plurality of walls defining an interior cavity, a supply valve defined in one wall of the plurality of walls, a return valve defined in one wall of the plurality of walls, and a chiller positioned in the interior cavity, the chiller including a heat exchange unit and an air circulator to provide cooled airflow from the chiller galley cart, the chiller being coupled to the supply valve and the return valve, wherein the heat exchange unit of the chiller comprises an evaporator, a compressor, a condenser and an expansion valve positioned in the interior cavity and is coupled in flow communication to the supply valve and the return valve to provide the cooled airflow from the chiller galley cart;
• coupling the supply valve of the chiller galley cart to the supply port to provide cooled airflow from the chiller to the supply duct;
• and
• coupling the return valve of the chiller galley cart to the return port to provide return air from the return duct to the chiller.
