Air conditioner

An air conditioner comprising:

• an outdoor unit;
• and
• an indoor unit, wherein
• the outdoor unit and the indoor unit are connected to each other by a refrigerant pipe to form a refrigerant circuit,
• the outdoor unit includes a compressor and an outdoor heat exchanger,
• the indoor unit includes an expansion valve, an indoor heat exchanger, an air supply device configured to supply outdoor air into a room through an air supply passage, and an air discharge device configured to discharge indoor air out of the room through an air discharge passage,
• the indoor heat exchanger is configured to allow air flowing through the air supply passage or air flowing through the air discharge passage to flow through the indoor heat exchanger,
• the indoor unit further includes a switching unit configured to switch whether or not to allow the indoor air flowing through the air discharge passage to flow through the indoor heat exchanger,
• the indoor heat exchanger includes a first indoor heat exchanger and a second indoor heat exchanger,
• the indoor unit further includes a controller configured to control an operation of the switching unit,
• the switching unit is configured to adjust an airflow rate of the indoor air flowing through the second indoor heat exchanger, and
• the controller controls the switching unit to adjust the airflow rate of the indoor air flowing through the second indoor heat exchanger so as to adjust an amount of heat exchanged by the first indoor heat exchanger in the air supply passage.

• the indoor unit further includes a controller configured to control an operation of the switching unit,
• the first indoor heat exchanger is disposed in the air supply passage,
• the second indoor heat exchanger is disposed in a common air passage, and the controller controls the switching unit to switch one of the outdoor air and the indoor air to flow through the common air passage, and
• the controller controls the switching unit to allow the indoor air to flow through the second indoor heat exchanger so as to suppress an amount of heat exchanged by the first indoor heat exchanger in the air supply passage.
