Abstract
A rotary compressor includes a cylindrical casing, an electric motor, and a compression mechanism. The cylindrical casing has first and second end plates ends in an axial direction. The electric motor is a variable-speed electric motor. The electric motor is disposed in the casing in which a first space is sandwiched between the electric motor and the first end plate. The compression mechanism is disposed in the casing in which a second space is sandwiched between the compression mechanism and the electric motor. The compression mechanism is coupled with the electric motor. The rotational compressor satisfies 0.8≤(A+B)*D/(Vcc*Nmax)≤1.0. An axial length of the first space is A, an axial length of the second space is B, an inner diameter of the casing is D, a suction volume per rotation of the compression mechanism is Vcc, and a maximum rotational speed of the compression mechanism is Nmax.
