Compressor assembly

The invention discloses a compressor assembly. The compressor assembly comprises a compressor, a liquid storage device and a heat-insulating pipe, wherein the compressor comprises a shell and a compression mechanism arranged in the shell; the compression mechanism comprises a main bearing, a cylinder assembly, an auxiliary bearing and a crankshaft; the crankshaft penetrates through the main bearing, the cylinder and the auxiliary bearing; the cylinder assembly comprises a cylinder; the cylinder is provided with a compression cavity and a gas absorbing hole which are communicated with each other; the liquid storage device is arranged outside the compressor and is provided with a gas outlet pipe; the free end of the gas outlet pipe extends into the gas absorbing hole and is communicated with the compression cavity; the heat-insulating pipe is sheathed outside the gas outlet pipe and is separated from the outer circumference wall of the gas outlet pipe so as to define a heat-insulating cavity; one end of the heat-insulating pipe is fixed with the gas outlet pipe positioned outside the shell, and the other end of the heat-insulating pipe extends into the gas absorbing hole and is fixed with the inner wall of the gas absorbing hole. According to the compressor assembly disclosed by the invention, by arrangement of the heat-insulating pipe, the temperature constancy of absorbing-in refrigerant and the stability of the absorbing-in amount of the refrigerant are effectively improved, so that the volume efficiency and the overall performance of the compressor are improved.
