機。 In an air conditioner in which a heat medium compression cycle is configured from an outdoor heat exchanger and an indoor heat exchanger, a room temperature sensor for detecting room temperature and an exchanger temperature sensor for detecting the temperature of the indoor heat exchanger are provided. and a control device that determines the defrosting operation time of the outdoor heat exchanger, and the control device measures the temperature difference between the room temperature and the indoor heat exchanger based on temperature signals from the room temperature sensor and the exchanger temperature sensor. A function that calculates at regular intervals, and when the calculated value before defrosting increases from the calculated value just before that, the temperature difference at that time is determined to be the maximum value, and the time from that time to the start of defrosting is set. a function to calculate the temperature difference at the time of defrosting, a function to calculate the difference between the maximum value of the temperature difference before defrosting and a temperature difference at the time of defrosting, and each of the output values of the various functions. An air conditioner characterized by having a function of determining a required defrosting time based on the following criteria.
