PROBLEM TO BE SOLVED: To provide an air conditioner that achieves a comfortable humidity environment without using a humidity sensor by setting a comfortable dew point temperature as a piping temperature target value of an evaporator.SOLUTION: The air conditioner comprises: heat pump control means 20 for controlling an expansion valve opening and a compressor rotation speed of heat pump means; air volume correction means 16 for correcting the volume of air supplied into a room; indoor air temperature setting means 22 for setting a desired indoor air temperature; indoor air temperature detection means 13 for detecting a room temperature; piping temperature detection means 5 for detecting a piping temperature of an evaporation heat exchanger; and radiation temperature detection means 6 for detecting an activity level of the human body from a variation in indoor radiation temperature distribution during a predetermined time period. When the room temperature is close to the desired temperature, the heat pump control means and the air volume correction means function to make the piping temperature of the evaporation heat exchanger close to a desired dew point temperature, and the dew point temperature is corrected depending on the activity level of the human body. |
