Abstract
The invention belongs to the technical field of air conditioning, and particularly relates to an air conditioner and a control method of the air conditioner. The air conditioner comprises a variable-volume double-rotor compressor, an outdoor heat exchanger, a throttle component and an indoor heat exchanger connected into a loop, and also comprises a four-way valve and a three-way valve, wherein the outdoor heat exchanger and the indoor heat exchanger are selectively communicated with the variable-volume double-rotor compressor through the four-way valve; two inlets of the three-way valve are connected with an exhaust side and a first air suction port of the variable-volume double-rotor compressor respectively; and an outlet of the three-way valve is connected with a second air suction port of the variable-volume double-rotor compressor. According to the running condition of the air conditioner, the variable-volume double-rotor compressor is in a double-rotor mode at high frequency, and can be in a single-rotor mode or the double-rotor mode at low frequency. Because the variable-volume double-rotor compressor is in the double-rotor mode at high frequency, the air conditioner can realize high-capacity output; and because one rotor is bypassed at low frequency, the air conditioner not only has small vibration, but also realizes low power and high energy efficiency.
