Abstract
PURPOSE: To enable to shorten a defrosting operating time as compared with a heating operation time, by a method wherein, in a defrosting operation method at a heating operation time, when a coolant evaporating temperature falls to a set value from an atmosphere temperature, a compressor is reduced in a rotative speed.
CONSTITUTION: If frost forms on an outdoor heat exchanger 2 during the heating operation and a detecting temperature Te of a coolant evaporating temperature detector 11 falls down to a control starting coolant temperature T1 decided by an atmosphere temperature detected by a detector 14, a compressor 1 is reduced in a rotative speed so that the temperature Te is brought into a constant state by means of a defrosting controller 15 and a controller 16. This approximately makes a frosting speed uniform without having accelerated, and if a room temperature TR falls to a defrosting starting temperature T3, a 4-way valve is switched to perform a defrosting operation in a reverse cycle. This delays the forming of frost through the reduction of the rotative speed of the compressor 1, which results in enabling to last a heating operation for a long period of time.
