PURPOSE: An air conditioning unit with low air flow resistance is provided to reduce air flow resistance while reducing the size and to facilitate smooth discharge of solidified water. CONSTITUTION: In an air conditioning case(201), an air inlet(210) and air outlets(290a,290b,290c) are formed to the upper part, a U-shaped air passage is formed to the inside, and a solidified water discharge outlet(240) is formed to the lower part. The U-shaped air passage has a downward passage(220), in which air flows downward from the air inlet, and an upward passage(270) in which air flows upward toward the air discharge outlet from the lower part of the downward passage. An air conditioning unit with low air flow resistance has an evaporator cooling air, a heater core(260) heating air, temperature doors(250a,250b) guiding air passing through the evaporator to make the air pass through the heater core or bypass the heater core; and discharge doors(280a,280b,280c) opening and shutting the air outlets. The evaporator is approximately horizontal to the downward passage. The heater core is approximately perpendicular to the upward passage. The temperature door is arranged between the evaporator and the heater core.
