Description

Technical Field

[0001] The present application belongs to the field of equipment technology, and in particular relates to a compressor assembly and equipment having the same. Background Art

[0002] Currently, existing horizontal rotor compressor assemblies are usually equipped with a gas-liquid separator outside the shell for separating the gaseous refrigerant.

[0003] However, due to system height restrictions, the external gas-liquid separator is typically designed with a small effective volume, which significantly impacts the gas-liquid separation on the suction side of the compressor assembly. This is particularly true for variable-frequency models, which are prone to insufficient suction volume during high-frequency operation, impacting compressor assembly performance. Furthermore, the gas-liquid separator is located on the side of the compressor assembly, shifting the compressor's center of mass toward the external gas-liquid separator. This causes the center of mass and the center of rotation to be off-axis, and the internal balancing structure of the compressor cannot be used to balance this, leading to increased vibration.
