Problems solved by technology

[0002] Existing commonly used rotary compressors and piston compressors require a large amount of lubricating oil for lubrication, cooling and sealing of the compression pump body, and it is impossible to completely separate the compatible lubricating oil from the refrigerant. The exhaust of the compressor must have lubricating oil
The lubricating oil not only affects the heat exchange efficiency of the two heat exchangers in the system, but also the power consumption of the self-circulation is useless

Abstract

The invention discloses a centrifugal compressor and a room air conditioner with the same. The centrifugal compressor includes: a casing, a motor, a crankshaft, a compression pump body, an oil supply device and bearings, and the casing has an exhaust port and an air return port. The motor is arranged in the casing, and the motor includes a stator and a rotor. The crankshaft is arranged in the casing, and the crankshaft cooperates with the rotor to be driven to rotate by the rotor. The compression pump body is arranged in the casing, and the compression pump body includes a volute and a pinch wheel, the pinch wheel is covered on the crankshaft, and the air outlet end of the pinch wheel corresponds to the air inlet end of the volute. The oil supply device is located in the bearing, and the oil supply device is configured to supply oil to the crankshaft to lubricate the crankshaft and recover the lubricating oil on the crankshaft to form an oil circuit. According to the centrifugal compressor of the present invention, the lubricating oil is prevented from being discharged from the exhaust port, and the function loss of oil circulation is reduced.

Description

technical field [0001] The invention relates to the field of compressors, in particular to a centrifugal compressor and a room air conditioner with the same. Background technique [0002] Existing commonly used rotary compressors and piston compressors require a large amount of lubricating oil for lubrication, cooling and sealing of the compression pump body, and it is impossible to completely separate the compatible lubricating oil from the refrigerant. The exhaust of the compressor must have lubricating oil. The lubricating oil not only affects the heat exchange efficiency of the two heat exchangers in the system, but also the power consumption of the self-circulation is useless. Contents of the invention [0003] The present invention aims to solve one of the technical problems in the related art at least to a certain extent. [0004] For this reason, the present invention proposes a centrifugal compressor, which prevents lubricating oil from being discharged from the...
