Hitachi water source heat pump compressor

How does the air conditioning compressor work? The air-conditioning compressor is also called a rotary (rotor) compressor, and its working principle is to rely on an eccentric rotor under the action of spring force, the compressor, and the eccentric rotor are always in contact with the container separated by the sliding container Changes to achieve a process of compression. When the eccentric rotor rotates, the volume of the container changes and the gas is compressed.
