Embodiment 1

[0034] This embodiment provides a liquid distributor, including a liquid distributor main body 1. A flow channel 2 for circulating refrigerant is provided inside the liquid distributor main body 1. The flow area of ​​the flow channel 2 is defined as S, that is, the flow area is limited. The cross-sectional area of ​​the channel 2 is S, and the working volume of the compressor is limited to V, that is, the working volume of the compression chamber of the cylinder 5 used in the compressor is V, 5≤S / V≤30.

[0035] This design provides a better solution for the selection and manufacture of compressors and liquid separators. The flow area of ​​the internal channel 2 of the liquid separator main body 1 is determined according to the working volume of the compressor and satisfies 5≤S / V≤30, so that the effect of the liquid separator can be better when used with the compressor, so as to improve the energy efficiency (COP) and cooling capacity of the compressor using the liquid separato...

Embodiment 2

[0037] This embodiment is a specific implementation of Embodiment 1. In this embodiment, the number of flow channels 2 in the liquid distributor body 1 is limited to one, so that the compressor used in conjunction with it is a single suction compressor, such as figure 1 As shown, at this time, the ratio of S / V is limited to 10 to 30, that is, 10≤S / V≤30, so that the liquid separator has a better effect, and the single-suction compressor has a higher energy efficiency and cooling capacity.

[0038] The following tabular data can be obtained from experiments and practice, Figure 5 is the variation curve of single suction compressor COP with S / V, Image 6 It is a graph showing the variation of cooling capacity of single-suction compressor with S / V. When 10≤S / V≤30, the COP (energy efficiency) and cooling capacity are at an optimal level, and the COP increases with the increase of the S / V ratio, and the cooling capacity decreases with the increase of the S / V ratio. When S / V30, ...

Embodiment 3

[0040] This embodiment is another specific implementation of embodiment 1. In this embodiment, the number of flow passages 2 in the liquid separator main body 1 is limited to two, so that the compressor used in conjunction with it is a double suction compressor, such as figure 2 As shown, at this time, the ratio of S / V is limited to 5 to 25, that is, 5≤S / V≤25, so that the liquid separator has a better effect, and the single-suction compressor has a higher energy efficiency and cooling capacity.

Abstract

The invention relates to a liquid distributor, a compressor and an air conditioning system, and belongs to the technical field of refrigeration. The liquid distributor comprises a liquid distributor main body, wherein a flow channel for circulation of a refrigerant is arranged in the liquid distributor main body, the flow area of the flow channel is S, the working volume of the compressor is V, and S / V is larger than or equal to 5 and smaller than or equal to 30. By means of the limitations, the liquid distributor can have better effect, and refrigerating capacity and energy efficiency of thecompressor matched with the liquid distributor are higher. The compressor adopts the liquid distributor, and the air conditioning system adopts the compressor, so energy efficiency and refrigerating capacity of the compressor can reach better level, and the air conditioning system has better effect.

Description

technical field [0001] The invention belongs to the technical field of refrigeration, and in particular relates to a liquid separator, a compressor and an air conditioning system. Background technique [0002] With the development of the air-conditioning industry and the improvement of air-conditioning energy efficiency levels, the requirements for energy efficiency and reliability of compressors are getting higher and higher. Air-conditioning energy efficiency and reliability are important indicators for evaluating the quality of air-conditioning. A liquid separator is required on the compressor for gas-liquid separation. The liquid separator is provided with flow channels for circulating gas (refrigerant). The ratio between the flow area of ​​the flow channels in the liquid separator and the working volume of the compressor is important for compression The energy efficiency and cooling capacity of the machine have a great influence. [0003] However, in the liquid separat...
