Pressure decoupling of air intake drainage and drainage of main housing

A drainage system for draining water from an air intake housing and from an air distribution housing of an air conditioning system into an environment, the drainage system comprising:

• a fan causing air to flow through the air conditioning system, wherein the air intake housing is disposed upstream of the fan with respect to a direction of flow of the air through the air conditioning system and wherein the air distribution housing is disposed downstream of the fan with respect to the direction of flow of the air through the air conditioning system;
• and
• a drainage opening draining water into the environment, the drainage opening formed on a lower shell of the air distribution housing and divided into a first drainage area for water from the air intake housing and a second drainage area for water from the air distribution housing, the first drainage area for water from the air intake housing formed by a terminal area of a duct routing water from the air intake housing, wherein the duct extends through an internal space defined by the lower shell of the air distribution housing and fluidly separates the water passing through the duct upstream of the first drainage area from the water passing through the internal space of the lower shell upstream of the second drainage area, wherein the first drainage area outlets directly to the environment and the second drainage area outlets directly to the environment, wherein the duct is angled vertically in the terminal area of the duct within the air distribution housing.

• an air intake housing disposed upstream of the fan with respect to a direction of flow of the air through the air conditioning system;
• an air distribution housing disposed adjacent the air intake housing and downstream of the fan with respect to the direction of flow of the air through the air conditioning system, the air distribution housing including a lower shell;
• a first drainage area formed by a terminal area of a duct routing water from the air intake housing, the first drainage area draining water to the environment from the air intake housing, wherein the duct extends through an internal space defined by the lower shell of the air distribution housing;
• and
• a second drainage area draining water to the environment from the air distribution housing, the first drainage area and the second drainage area formed on the lower shell of the air distribution housing, wherein the duct fluidly separates the water passing through the duct upstream of the first drainage area from the water passing through the internal space of the lower shell upstream of the second drainage area, wherein the first drainage area outlets directly to the environment and the second drainage area outlets directly to the environment, and wherein the duct is integrally formed with the lower shell.
