Embodiment Construction

[0019] The air conditioner according to the first aspect of the present invention includes: an indoor blower fan that blows air into a room; a human body detection sensor that detects the movement of a human body; a horizontal deflection blade that deflects air from the indoor blower fan in a horizontal direction; and a control unit. , which controls the heating operation and defrosting operation, determines whether there is a person based on the detection result of the human detection sensor, and controls the horizontal deflection blade. The control unit orients the horizontally deflected vane in the direction of an unoccupied area during the defrosting operation.

[0020] According to this aspect, by storing heat in an unoccupied area before the defrosting operation, it is possible to suppress a drop in the sensible temperature during the defrosting operation.

[0021] The air conditioner according to the second aspect of the present invention is based on the first aspect, a...

Abstract

PROBLEM TO BE SOLVED: To provide an air conditioner capable of performing a defrosting operation while maintaining comfort of a user.SOLUTION: An air conditioner includes: human body detection means for detecting movement of a human body; and left and right air direction change blade for changing the direction of the blown out air horizontally. Then, before a defrosting operation, by controlling the direction of the left and right air direction change blade so as to blow out warm air in a region other than the region which has been detected to have a person by the human body detection means, heat can be stored in the region without a person. Thus, change in a sensible temperature of a person in the defrosting operation can be suppressed.

Description

technical field [0001] The present invention relates to an air conditioner having a defrosting operation function. Background technique [0002] In a conventional heat pump air conditioner, when frost forms on the outdoor heat exchanger during heating operation, the four-way valve is switched to switch from the heating cycle to the cooling cycle to perform the defrosting operation. In this case, since the blowing of warm air is stopped during the defrosting operation, there is a problem that the warming feeling is lost. [0003] In order to solve this problem, it has been proposed to defrost the waste heat from the compressor during the heating operation, which is installed in the outdoor unit and stored in a heat storage tank filled with a heat storage material (for example, refer to Japanese Patent Application Laid-Open No. 3 - Bulletin No. 31666). [0004] However, in the above-mentioned conventional technology, at least a heat storage tank is required, and there is a p...
