Air conditioner and method of controlling air conditioner

An air conditioner comprising:

• an indoor fan;
• a compressor;
• an expansion valve configured to control a refrigerant flow rate;
• an indoor temperature sensor;
• memory, comprising one or more computer-readable storage media, storing instructions;
• and
• at least one processor comprising a processing circuit,
• wherein the instructions, when executed by the at least one processor individually or collectively, cause the air conditioner to:
• obtain an indoor temperature through the indoor temperature sensor,
• determine a dehumidification operation section among a plurality of different dehumidification operation sections according to a temperature difference between the indoor temperature and a set temperature set by a user, and
• perform a differential dehumidification operation of the air conditioner by controlling at least one of the indoor fan, the compressor, or the expansion valve, based on the determined dehumidification operation section.

One or more non-transitory computer-readable storage media storing instructions that, when executed by at least one processor of an air conditioner individually or collectively, cause the air conditioner to perform operations, the operations comprising:

• obtaining an indoor temperature through an indoor temperature sensor of the air conditioner;
• determining a dehumidification operation section among a plurality of different dehumidification operation sections according to a temperature difference between the indoor temperature and a set temperature set by a user;
• and
• performing a differential dehumidification operation of the air conditioner by controlling at least one of an indoor fan of the air conditioner, a compressor of the air conditioner, or an expansion valve of the air conditioner, based on the determined dehumidification operation section.
