Embodiment 1

[0021] Such as figure 2 As shown, the compressor piping system provided by the embodiment of the present invention includes the electromagnetic reversing valve 4 and the air return pipe 8 connected to the electromagnetic reversing valve 4, where two pipe sections of the air return pipe 8 are in the shape of a three-dimensional intersection Take control. This design, on the one hand, balances the tangential vibration of the compressor due to the unbalanced rotor mass, and on the other hand, improves the refrigerant gas column resonance caused by the pulsating force, thereby avoiding the mechanical structure resonance of each operating frequency, so that each The pipeline can work smoothly during operation, and the vibration generated is small, thereby improving the stress distribution on the surface of the pipeline. At the same time, it avoids the addition of assembly weights, anti-vibration glue, etc. in the existing piping, and reduces the cost of materials, production and ...

Embodiment 2

[0031] Such as Figure 4 As shown, the difference between this embodiment and the first embodiment is that the air return pipe 8 and the exhaust pipe 5 are distributed on the same side of the compressor body 7 .

Embodiment 3

[0033] Such as Figure 5 As shown, the difference between the present embodiment and the first embodiment is that the "U" section of the air return pipe 8 is formed by tangentially connecting multiple sections of arc tubes and straight tubes, such as two sections of arc tubes m, p and Three sections of straight pipes e, n and g are connected tangentially.

Abstract

The invention belongs to the technical field of refrigeration, and provides a compressor piping system and a refrigerating device. The compressor piping system comprises an electromagnetic directional valve and an air return pipe connected to the electromagnetic directional valve. Two pipe sections of the air return pipe are vertical crossing type walking pipes. According to the compressor piping system, the two pipe sections of the air return pipe are the vertical crossing type walking pipes, tangential vibration of a compressor caused by mass unbalance of a rotor is balanced, refrigerant air column resonance caused by fluctuating force is improved, resonance of mechanical structures at different working frequency is avoided, the pipeline can stably work in the operating process, generated vibration is small, and therefore the pipeline surface stress distribution state is improved. The compressor piping system can be applied to various refrigerating devices such as refrigerators and air conditioners, especially frequency conversion air conditioners.

Description

technical field [0001] The invention belongs to the technical field of refrigeration, and in particular relates to a compressor piping system and a refrigeration device. Background technique [0002] Single-cylinder rotary compressors are widely used in household air conditioners due to their high energy efficiency ratio and low manufacturing cost, and inverter air conditioners are no exception. However, when running at high speed, the unbalanced mass of the rotor leads to poor dynamic balance, which can easily cause vibration of the compressor body, especially the tangential vibration transmitted to the return air pipe to cause vibration of the compressor piping system. Moreover, the suction and discharge of the single-cylinder rotary compressor are intermittent and periodic, which makes the pressure pulsation of the refrigerant in the tube, especially in the case of high compression ratio, the periodic pulsation force is more obvious, making the air flow in the tube The p...
