[0025] The air outlet pipe 4 is provided with a plurality of air outlet hole groups 41 along the height direction; the air inlet pipe 5 is provided with a plurality of air inlet hole groups 51 along the height direction.

[0026] Specifically, when the pressure equalizing coupler described in this embodiment is in use, the air inlet interface 3 is connected to the exhaust ports of different compressors respectively, and the air outlet interface 2 is connected to the heat exchanger, so that the compressors are connected in parallel.

[0027] After being connected to the compressor and the heat exchanger, the pressure is equalized through the air inlet hole group 51 of the air inlet pipe 5 and the air outlet hole group 41 of the air outlet pipe 4, so that the pressure at the exhaust port of the compressor is gradually reduced under the action of the air inlet hole group 51, and the buffer cavity of the pressure equalizing coupler is used to balance the exhaust pressure of each compressor. In addition, under the action of the air outlet hole group 41, it is ensured that the pressure entering the heat exchanger from the air outlet interface 2 is the same, so as to avoid pressure blockage at the inlet of the heat exchanger and high-pressure alarm when the parallel system is running.

The above arrangement allows part of the gas to enter the buffer cavity 11 after passing through the bottom of the inlet pipe 5, and to enter the outlet pipe 4 after passing through the bottom of the outlet pipe 4, thereby further improving the pressure equalization effect.

[0029] In the pressure equalizing coupler described in this embodiment, the outlet pipe 4 is arranged in parallel with the inlet pipe 5. The above arrangement can further improve the pressure equalizing effect of the pressure equalizing coupler.
