A slider is movably arranged in a slider groove of the cylinder and abuts against the outer peripheral surface of the rotor piston to divide the refrigerant compressor working space into two spaces, an air suction cavity and an air exhaust cavity. When the motor is powered on, an electromagnetic field is generated by a stator coil, and the rotor cuts the magnetic force to generate power to drive the crankshaft of the pump body to rotate, so that the rotor piston rotates in the cylinder, continuously changing the volume of the air suction and exhaust cavities, inhaling low-temperature and low-pressure gaseous refrigerant, compressing it into high-temperature and high-pressure gaseous refrigerant and then discharging it from the pump body, and so on in a cycle; the high-temperature and high-pressure gaseous refrigerant generated by compression in the pump body passes through an exhaust pipe fixedly arranged at the top of the housing and is discharged, and is further transported through the connection of pipes to an air-conditioning main unit, etc. for refrigeration.
