摘要： Disclosed is a compressor (1). The compressor includes: a first cylinder (11), the first cylinder (11) being provided with a first gas intake (111) and a first gas outlet (112), the first air outlet (112) being connected to a predetermined heat exchanger; a second cylinder (12), the second cylinder (12) being provided with a second gas intake (121) and a second gas outlet (122), and the second gas outlet (122) being connected to the predetermined heat exchanger; and a gas pre-exhausting device (116). The gas pre-exhausting device (116) is provided on a cylinder block of the first cylinder (11) or on an upper end surface of the first cylinder (11) or a lower end surface of the first cylinder (11); the gas pre-exhausting device (116) includes a gas pre-exhausting port and a first control valve controlling the gas pre-exhausting port to be open or closed; and the gas pre-exhausting port is connected to the second gas intake (121). Further disclosed is an air conditioner system including the compressor (1). The compressor can greatly increase a volume of a small cylinder during a double-cylinder operation, thereby greatly reducing processing difficulty of the double-cylinder compressor used as a small capacity compressor, and meanwhile effectively improving efficiency of the small cylinder because of the increased volume of the small cylinder.
