Compressor and air conditioner with same

Abstract

The invention provides a compressor and an air conditioner with the same. The compressor according to the utility model includes a shell, a crankshaft arranged inside the shell, a first cylinder and a second cylinder. The first cylinder sleeves the crankshaft and is provided with one first slip sheet, and an inner cavity of the first cylinder is used for forming a first-level compression mechanism. The second cylinder is sleevedly arranged on the crankshaft and is provided with two second slip sheets, an inner cavity of the second cylinder is divided into two compression cavities by the two second slip sheets, and the two compression cavities of the second cylinder are respectively used for forming a second-level compression mechanism and a third-level compression mechanism. The first-level compression mechanism, the second-level compression mechanism and the third-level compression mechanism are successively in series connection along a flow passage of a compression fluid. The utility model also provides the air conditioner comprising the compressor. The second cylinder is arranged into two levels of compression mechanisms to improve the compression ability, so that the compressor can work normally under working conditions of ultra-low temperature and ultra-high temperature, so as to better meet customer requirements.

Description

technical field [0001] The invention relates to the field of compressors, in particular, to a compressor and an air conditioner having the same. Background technique [0002] Using the principle of rolling piston compressor to realize double-cylinder single-stage compression technology is relatively mature, and under the current world theme of high efficiency, energy saving and environmental protection, double-cylinder two-stage enthalpy increasing technology has been successfully applied to heat pump products, which is the first step of single-stage compression technology. Sublimation and embodiment of the theme of today's world. Under ultra-low temperature and ultra-high temperature conditions, the cooling and heating efficiency of the two-stage enthalpy-increasing compressor technology is limited and needs to be further improved. Contents of the invention [0003] The purpose of the present invention is to provide a compressor and an air conditioner with the same, so a...
