Embodiment Construction

[0018] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0019] Such as figure 2 The shown compressor includes a body in which a cooling oil passage 1 is arranged, and the compressor also includes a heat exchange channel 2 arranged at the suction cavity 3 of the body, and The first end of the heat exchange channel 2 communicates with the lubricating oil inlet of the body, and the second end communicates with the inlet of the cooling oil passage 1, and the high temperature lubricating oil is sent to the heat exchange channel 2 preferentially from the lubricating oil inlet Inside, the low-temperature refrigerant in the suction chamber 3 is used to exchan...

Abstract

The invention provides a compressor with a lubricating oil self-cooling function and an air conditioning system. The compressor comprises a compressor body and further comprises a heat exchange channel, wherein a cooling oil path is arranged in the compressor body; and the heat exchange channel is arranged in a gas suction cavity of the compressor body. By the adoption of the compressor with the lubricating oil self-cooling function and the air conditioning system, high-temperature lubricating oil can preferentially pass through the gas suction cavity for being cooled under the flow guiding action of the heat exchange channel, bearings can be cooled after the high-temperature lubricating oil is cooled, and the problem that the temperature of the lubricating oil for the bearings in the compressor is too high can be effectively solved; furthermore, the problem that in the prior art, the compressor structure is complex due to the additional arrangement of an oil cooling device can be solved; meanwhile, the flow rate of the lubricating oil for the bearings in the compressor can be reduced under the premise that the bearings can be sufficiently cooled when the temperature of the lubricating oil is low enough, and then the energy efficiency of the compressor and the oil separating efficiency can be compressor can be improved; and the problem that the lubricating oil enters the air conditioning system can be solved.

Description

technical field [0001] The invention relates to the technical field of compression equipment, in particular to a compressor and an air-conditioning system with the function of self-cooling lubricating oil. Background technique [0002] Compressor bearing lubricating oil is supplied by differential pressure. At present, all compressor manufacturers adopt the internal oil circulation structure of the compressor as follows: figure 1 As shown, the oil is supplied from the high-pressure main oil supply line, and the lubricating oil is divided into two lines, one is supplied to the bearing at the suction end of the rotor, and the other is supplied to the bearing at the exhaust end of the rotor, and finally returns to the low-temperature and low-pressure chamber of the compressor. The suction end of the compressor is a low-temperature and low-pressure suction cavity, and the exhaust end is a high-temperature and high-pressure exhaust cavity. The oil provided by the compressor to lu...
