Problems solved by technology
[0002] It is pointed out in the related art that the traditional two-cylinder compressor sucks the refrigerant from the liquid receiver into the compressor cylinder through the suction hole of the partition, the upper cylinder, or the lower cylinder for compression, in order to reduce the radial direction of the gas compression. Leakage problem, the thickness of the upper cylinder and the lower cylinder is continuously reduced. However, this will cause the suction aperture of the upper cylinder and the lower cylinder to be reduced, resulting in an increase in suction pressure loss, a decrease in energy efficiency, and a change in the rigidity of the compression mechanism. Poor, vibration and noise problems are more serious

The invention discloses a two-cylinder compressor and an air conditioner with the same. The two-cylinder compressor includes: a shell, a motor inside and a compression mechanism, and the compression mechanism includes a crankshaft, a main bearing, a first cylinder, a partition Plate, second cylinder and auxiliary bearing, the partition is arranged between the first cylinder and the second cylinder, the main bearing is located on the side of the first cylinder away from the partition, and the sub-bearing is located on the side of the second cylinder away from the partition , wherein, a through hole is formed on the partition, and the crankshaft passes through the through hole. The maximum transverse dimension L of the partition and the diameter D of the mounting hole satisfy: L / D≥3.8, and the maximum transverse dimension L of the partition and the diameter of the partition The thickness H of the plate satisfies: 4≤L / H≤11. According to the double-cylinder compressor of the present invention, by increasing the thickness and diameter of the partition, the rigidity and natural frequency of the compression mechanism are effectively improved, thereby improving vibration and noise problems.
Description
technical field [0001] The invention relates to the field of refrigeration equipment, in particular to a double-cylinder compressor and an air conditioner with the same. Background technique [0002] It is pointed out in the related art that the traditional two-cylinder compressor sucks the refrigerant from the liquid receiver into the compressor cylinder through the suction hole of the partition, the upper cylinder, or the lower cylinder for compression, in order to reduce the radial direction of the gas compression. Leakage problem, the thickness of the upper cylinder and the lower cylinder is continuously reduced. However, this will cause the suction aperture of the upper cylinder and the lower cylinder to be reduced, resulting in an increase in suction pressure loss, a decrease in energy efficiency, and a change in the rigidity of the compression mechanism. Poor, vibration and noise problems are more serious. Contents of the invention [0003] The present invention ai...
