Aircraft galley exhaust system and method of assembling same

摘要

An exhaust system for an aircraft galley chiller is provided. The exhaust system includes a galley having a chiller that includes an inlet, a condenser fan inlet, a condenser fan outlet proximate to chiller inlet, and a first flow of air through the condenser, an air ventilation outlet conduit that includes a second flow of air therethrough, and an ejector pump. The ejector pump includes a first airflow inlet, a second airflow inlet and an airflow outlet, wherein the first airflow inlet is coupled in flow communication with the condenser fan outlet, the second inlet is coupled in flow communication with the air ventilation outlet conduit. As the second airflow increases, the first velocity increases in a direction away from the galley chiller facilitating a decrease in temperature at the condenser fan inlet.

主权项

1. An exhaust system for an aircraft galley chiller, said exhaust system comprising:
a condenser comprising a fan, an airflow inlet and an airflow outlet, said fan operable to produce a first flow of air having a first pressure through said condenser from said airflow inlet to said airflow outlet, the first flow of air including a heated exhaust air exiting the aircraft galley chiller; a ventilation assembly comprising an air ventilation conduit including a second flow of air therethrough that is generated by a ventilation fan, the second flow of air having a second pressure that is higher than the first pressure; and an ejector pump comprising a first airflow inlet, a second airflow inlet and an airflow outlet, said first airflow inlet coupled in flow communication with said airflow outlet of said condenser to receive the first flow of air, said second airflow inlet coupled in flow communication with said second flow of air generated by the ventilation fan, said ejector pump configured to increase a velocity of the second flow of air entering said second airflow inlet to decrease the second pressure, wherein the decrease in the second pressure generates a suction force that increases evacuation of the first flow of air through said condenser to thereby decrease a temperature of the heated exhaust air entering said condenser airflow inlet.
