摘要： PROBLEM TO BE SOLVED: To provide an air conditioner and a control method thereof, capable of quickly matching a room temperature with a set temperature by means of automatic temperature control.SOLUTION: Room fans 23a and 23b send conditioning air. Room temperature sensors 27a and 27b detect a temperature of the room which is cooled or heated by the conditioning air blown out by the room fans 23a and 23b. A control section 18 reduces an air volume of the room fans 23a and 23b in principle when a difference between the set temperature and the room temperature detected by the room temperature sensors 27a and 27b becomes small. However, automatic temperature control is performed in such a way that the air volume of the room fans 23a and 23b is increased if the reduction in temperature difference within a set time period after the air volume of the room fans 23a and 23b is reduced goes below a set value set in advance.
