While cooling operation is continued, a compressor is stopped when a detection temperature Tm reaches a control temperature Tc that is a lower temperature than a set temperature Ts only by a bias temperature ΔTb, and rotation of a turbofan is stopped if a human body is not present in a room R, or the rotation of the turbofan is continued and a value of the detection temperature Tm is corrected to a correction detection temperature Ta that is a lower temperature than the detection temperature Tm only by a predetermined temperature correction amount ΔTm. While the correction detection temperature Ta is a temperature that is equal to or lower than the set temperature Ts (the control temperature Tc for prevention of hunting) (Ta=Tm−ΔTm≦Tc), the rotation of the turbofan is continued as long as a person is present in the room R, and thermo ON is resumed if the correction detection temperature Ta exceeds the set temperature Ts (Ta>Ts). |

1. An air-conditioning apparatus, comprising:
an outdoor unit housing a compressor, an outdoor heat exchanger, and an expansion valve each of which executes a part of a refrigeration cycle; an indoor unit housing an indoor heat exchanger that execute part of the refrigeration cycle; an indoor fan housed in the indoor unit, the indoor fan sucking indoor air that is air in a room in which the indoor unit is installed and supplying the indoor air to the indoor heat exchanger, and blowing the indoor air that has passed through the indoor heat exchanger into the room; an indoor-air temperature detector configured to detect a temperature of the indoor air; a human-body presence detector configured to detect presence of a human body in the room; an indoor-air temperature setting device configured to be operated to set a temperature of the indoor air; and a controller configured to control the refrigeration cycle and the indoor fan, based on a detection temperature that is the temperature of the indoor air detected by the indoor-air temperature detector, human-body information detected by the human-body presence detector, and a set temperature that is the temperature of the indoor air set by the indoor-air temperature setting device, wherein when the indoor heat exchanger functions as an evaporator, the controller stops the refrigeration cycle if the detection temperature is lower than the set temperature, and stops the indoor fan if the human-body information indicates that the human body is not present, and operates the indoor fan if the human-body information indicates that the human body is present, and when the refrigeration cycle is stopped because the detection temperature is lower than the set temperature and the indoor fan is operated because the human-body information indicates that the human body is present, the controller corrects the detection temperature to be lower only by a predetermined temperature correction amount, and when a correction detection temperature that is the corrected detection temperature becomes higher than the set temperature, the controller resumes operation of the refrigeration cycle. |
