Vortex-type refrigeration compressor with conical exhaust passageway and divergent inlet structure

Abstract

The invention relates to a wortex-type refrigeration compressor with a conical exhaust passageway and divergent inlet structure. The wortex-type refrigeration compressor comprises a housing, a static scroll plate, a moving scroll plate and a motor. The housing is provided with an exhaust pipe. The axial middle of the static scroll plate is provided with a through exhaust passageway. The wortex-type refrigeration compressor is characterized in that the exhaust pipe comprises an outer exhaust branched pipe and two or more exhaust branched pipes, the outer exhaust branched pipe extends to the outer part of the housing 1, the two or more exhaust branched pipes are arranged in the housing 1, included angles of the two or more exhaust branched pipes and the outer branched pipe are equal, the exhaust passageway is in a shape of a conical hole, a large-diameter end opening of the exhaust passageway is communicated with an exhaust chamber and a small-diameter end opening of the exhaust passageway is corresponding to the moving scroll plate so that exhaust flow fields of a refrigerant in the static scroll plate are basically same in use of the exhaust passageway and the compressor. In the exhaust pipe structure, refrigerant gas is fed into the outer exhaust branched pipe by the two or more exhaust branched pipes, and refrigerating machine oil carried by the refrigerant gas flows downward back into the compressor under the action of gravity so that a refrigeration compressor oil yield is effectively controlled.

Description

technical field [0001] The invention belongs to the technical field of refrigeration compressors, in particular to scroll refrigeration compressors. Background technique [0002] In recent years, the energy saving and environmental protection of energy-consuming equipment has attracted widespread attention from the society, and reducing the power consumption of refrigeration and air-conditioning products has become an important issue. As the main component of the air conditioner, it is of great significance to realize high-efficiency operation of the compressor in the vapor compression refrigeration system. [0003] The scroll refrigeration compressor is a volumetric compression compressor, which is widely used in household and commercial refrigeration and air-conditioning systems. A closed refrigerant gas storage space is formed inside the container formed by its compression components. , It is mainly composed of a fixed scroll, an orbiting scroll, a crankshaft driving th...

Problems solved by technology

A large amount of oil mist in the compressor housing 1 will be directly discharged to the refrigeration system through the exhaust pipe 10 together with the refrigerant gas, which will change the flow and heat transfer properties of the refrigerant in the system, cause additional heat transfer resistance, and affect the heat exchanger. performance, causing serious harm to the long-term performance of the refrigeration system
