Title
(EN) Compressor and refrigeration equipment
(ZH) 压缩机和制冷装置
Abstract
(EN) The invention provides a compressor and refrigeration equipment. The compressor comprises a shell, a compression assembly, a motor, an oil sump and an oil return channel. A cavity is formed in the shell; one part of the compression assembly is connected with the shell, and located in the cavity; and the cavity is divided into a first cavity and a second cavity by the compression assembly. One partof the motor is arranged in the first cavity, and the part, located below the central axis of the motor, of the shell is a first shell. The oil sump is arranged in the second cavity. The oil return channel is arranged on the compression assembly, and provided with an oil inlet facing the first cavity. According to the compressor, the distance between a dividing line in the oil inlet and the innerside wall of the first shell, and the inner diameter of the shell meet the preset relationship, and the area of the part, located below the dividing line, of an oil through area and the area of the oil inlet meet a certain relationship, so that the oil inlet is hard to expose in refrigerants; the recovery efficiency of lubricating oil is improved, and the oil level fluctuation is relatively stable; and the oil circulation ratio of the compressor is reduced, and the reliability and energy efficiency grade of the compressor are improved.
(ZH) 本发明提供了一种压缩机和制冷装置,压缩机包括壳体、压缩组件、电机、油池和回油通道。壳体构造出腔体;压缩组件的一部分与壳体连接并位于腔体内,压缩组件将腔体分为第一腔体和第二腔体。电机的一部分设置在第一腔体内,位于电机的中心轴线下方的部分壳体为第一壳体。油池设置在第二腔体内。回油通道设置在压缩组件上,回油通道具有朝向第一腔体的进油口。本发明通过令进油口内的分隔线与第一壳体的内侧壁之间的距离与壳体的内径满足预设关系,且位于分隔线下的通油区的面积与进油口面积满足一定关系,从而使进油口难以暴露在冷媒中,提升润滑油的回收效率,使得油面波动相对平稳,降低压缩机的吐油量并提升压缩机的可靠性和能效等级。
