The invention discloses a double-compressor pipeline structure. The double-compressor pipeline structure comprises two compressors, a Y-shaped tee and a plate heat exchanger, wherein distribution pipes are respectively arranged between the two compressors and the Y-shaped tee, the compressors communicate with the Y-shaped tee by virtue of the distribution pipes, the plate heat exchanger and the Y-shaped tee are arranged in parallel, a liquid outlet pipe is arranged between the plate heat exchanger and the Y-shaped tee, the liquid outlet pipe is perpendicular to the plate heat exchanger, and the plate heat exchanger communicates with the Y-shaped tee by virtue of the liquid outlet pipe. According to the double-compressor pipeline structure, the Y-shaped tee and the plate heat exchanger are arranged in parallel, and additionally, the liquid outlet pipe is perpendicular to the plate heat exchanger, so that refrigerant is uniformly distributed to each compressor, and the use effect and service life of the compressors are effectively improved.
