1. An air conditioner having six ports, comprising:
a casing in which at one end, a first discharge port, a second discharge port, and an air supply port disposed between the first discharge port and the second discharge port are formed, and at the other end, a first outdoor air intake port, a second outdoor air intake port, and an indoor air intake port disposed between the first outdoor air intake port and the second outdoor air intake port are formed;
a partition wall part dividing an inner space of the casing into a first passage one end of which faces the first discharge port and the air supply port, and the other end of which faces the first outdoor air intake port and the indoor air intake port, and a second passage one end of which faces the second discharge port and the air supply port, and the other end of which faces the second outdoor air intake port and the indoor air intake port;
a direction change damper connecting the air supply port and the indoor air intake port to the first passage or the second passage;
a waste heat recovery heat exchanger in which air in the first passage moving to the second passage through the partition wall part and air in the second passage moving to the first passage through the partition wall part is subject to heat exchange with each other;
a first air volume control damper for controlling an opening rate of a space between the waste heat recovery heat exchanger and the casing in the first passage; and
a second air volume control damper for controlling an opening rate of a space between the waste heat recovery heat exchanger and the casing in the second passage.
