<p>PROBLEM TO BE SOLVED: To solve a problem in a conventional air conditioner that an unnecessary preheating operation is performed as the preheating operation is started when an outside air temperature is lower than a prescribed temperature even when start setting for automatically starting a heating operation is performed.SOLUTION: When a start setting is performed (S1:Yes), an air conditioner starts a preheating operation (S5), when a prescribed condition based on at least one of an outside air temperature detected by an outside air temperature detection sensor, and a discharge temperature of a compressor detected by a discharge temperature detection sensor is satisfied (S3:Yes) at a time within a prescribed time T before a heating start time based on the start setting (S4:Yes).</p> |
