Liquid separator, compressor, air conditioner

Abstract

The invention provides a liquid separator, a compressor, and an air conditioner, wherein the liquid separator includes a first ring wall and a second ring wall located radially outside the first ring wall, the first ring wall and the second ring wall A liquid separation space is formed between the walls, and a separator is provided in the liquid separation space to separate the liquid separation space into a first liquid separation chamber and a second liquid separation chamber, wherein the first liquid separation chamber corresponds to the first ring wall The first wall area, the first wall area can conduct heat exchange with the shell of the compressor, the second liquid separation chamber corresponds to the second wall area of ​​the first ring wall, the distance between the second wall area and the shell of the compressor insulated. According to the present invention, by reasonably dividing the liquid separation space into mutually independent liquid separation chambers, and conducting heat conduction or heat insulation treatment between the liquid separation chamber and the shell of the compressor according to the difference between the cooling and heating modes of the air conditioner, it can satisfy The refrigerant in different states in the liquid separator has different requirements for heat transfer between the compressor body and the external environment.

Description

technical field [0001] The invention belongs to the technical field of air conditioning, and in particular relates to a liquid separator, a compressor and an air conditioner. Background technique [0002] In the upstream industry of traditional air-conditioning compressors, the liquid separator used in the compressor is usually a cylindrical barrel structure. The liquid separator barrel is not in contact with the surface of the compressor shell, and there is no heat transfer between the two. The diagram is as follows figure 1 As shown, when this kind of liquid separator is used in the heating mode of the air conditioner, the heat generated by the compressor itself cannot be effectively used, and the compressor is prone to the problem of suction with liquid or even liquid hammer, which affects the energy efficiency and reliability of the compressor; in addition, there are Part of the liquid separator has a special-shaped structure, and the surface of the cylinder is in conta...

Problems solved by technology

[0002] In the upstream industry of traditional air-conditioning compressors, the liquid separator used in the compressor is usually a cylindrical barrel structure. The liquid separator barrel is not in contact with the surface of the compressor shell, and there is no heat transfer between the two. The diagram is as follows figure 1 As shown, when this kind of liquid separator is used in the heating mode of the air conditioner, the heat generated by the compressor itself cannot be effectively used, and the compressor is prone to the problem of suction with liquid or even liquid hammer, which affects the energy efficiency and reliability of the compressor; in addition, there are Part of the liquid separator has a special-shaped structure, and the surface of the cylinder is in contact with the surface of the compressor shell, and there is heat transfer between the two. The schematic diagram of the structure is as follows figure 2 As shown, when this liquid separator is used in the cooling mode of the air conditioner, the heat transferred from the compressor to the liquid separator is harmful heat, which will cause the compressor to overheat the suction, increase the suction specific volume and suction temperature of the compressor, and reduce the The energy efficiency of the compressor increases the discharge temperature of the compressor, thereby reducing the reliability of the compressor. That is, the conventional non-contact and contact liquid separators cannot meet the requirements of the refrigerant in the liquid separator of the air-conditioning compressor under different working conditions for heat transfer. Different requirements, that is, no heat transfer is required for cooling, and heat transfer is required for heating
