Abstract
An air conditioner having six ports is described. The inner space of a casing having six inlet/outlets including a first discharge port, a second discharge port, a first outdoor air intake port, a second outdoor air intake port, and an interior air suction port is divided by a partition wall to form a first passage and a second passage. A waste heat recovery heat exchanger is provided between the first passage and the second passage. The air flow direction and the air volume can be controlled by using a direction change damper, a first air volume control damper, and a second air volume control damper.
