PROBLEM TO BE SOLVED: To acquire an air conditioner and the like capable of optimizing timing of compressor frequency restriction and capable of suppressing cooling capacity suppression to a necessary minimum, in performing dew condensation avoidance of an indoor unit.SOLUTION: The air conditioner includes: an outdoor unit 1 having a variable displacement compressor; an indoor unit 2 having an indoor heat exchanger 21; a liquid pipe temperature sensor 25 for detecting an operational state temperature of the indoor unit 2; a temperature/humidity sensor 24 for detecting a temperature and humidity of indoor air; and a control device 40 for performing dew condensation avoidance control for avoiding dew condensation in the indoor unit 2 in the case where dew condensation is predicted to occur in the indoor unit 2 during a cooling operation. The control device 40 sets a determination value for determining whether or not dew condensation occurs in the indoor unit 2 on the basis of the temperature and humidity detected by the temperature/humidity sensor 24 during the cooling operation, and when an indoor heat exchanger temperature (liquid pipe temperature) of the indoor unit 2 detected by the liquid pipe temperature sensor 25 is equal to or less than the determination value, it performs dew condensation avoidance control for controlling compressor frequency so that the indoor heat exchanger temperature of the indoor unit 2 surpasses the determination value. |
