Compressor assembly

The utility model discloses a compressor assembly. The compressor assembly comprises a compressor, a liquid accumulator and a heat insulation pipe, wherein the compressor comprises a casing and a compression mechanism arranged in the casing; the casing mechanism comprises a main bearing, an air cylinder assembly, a secondary bearing and a crankshaft, and the crankshaft penetrates through the main bearing, the air cylinder assembly and the secondary bearing; the air cylinder assembly comprises an air cylinder, a compression cavity and air suction holes which are mutually communicated are formed in the air cylinder, the liquid accommodator is arranged outside the compressor and provided with an air outlet pipe, and a free end of the air outlet pipe stretches into the air suction holes and is communicated with the compression cavity; the heat insulation pipe is arranged outside the air outlet pipe in a sleeving manner and is spaced from the peripheral wall of the air outlet pipe, and a heat insulation cavity is defined; one end of the heat insulation pipe is fixed with the air outlet pipe located outside the casing, and the other end of the heat insulation pipe stretches into the air suction holes and is fixed with the inner walls of the air suction holes. According to the compressor assembly, the constancy of the temperature for refrigerant suction and the stability of a refrigerant suction volume can be effectively improved by the aid of the heat insulation pipe, so that the volume efficiency and the overall performance of the compressor are improved.
