Oil-gas separator and air-conditioning system having the same

Abstract

The invention discloses an oil-gas separator and an air conditioning system with the oil-gas separator. The oil-gas separator comprises a shell, wherein an oil collection opening is formed in the bottom wall of the shell, an air baffle plate is arranged on the inner wall of the shell, an air exhaust pipe is arranged on the shell; an air inlet pipe, one end of the air inlet pipe extending into the shell towards the air baffle plate, and an oil-gas mixture entering the shell from the air inlet pipe colliding the air baffle plate; an air homogenization plate which is arranged in the shell, a plurality of ventilating holes are formed in the air homogenization plate, and an oil filter assembly which is arranged in the shell, wherein the air baffle plate is located at the upstream of the air homogenization plate in the flowing direction of the oil-gas mixture; the air homogenization plate is located at the upstream of the oil filter assembly, and the air homogenization plate and the oil filter assembly are arranged in a spacing manner; the air exhaust pipe is located at the downstream of the oil filter assembly. The oil-gas separator disclosed by the invention can enhance the oil separation effect, and is simple in structure; the oil separation principle is simple and reliable.

Description

technical field [0001] The invention relates to the field of refrigeration, in particular to an oil-gas separator and an air-conditioning system with the same. Background technique [0002] With the increasing demand for environmentally friendly air conditioners, high efficiency and energy saving have become a new direction for the development of screw chiller technology, and the oil return problem in screw chillers is a key factor affecting the efficiency of the unit, because the oil return is not timely , It will cause a large amount of oil in the system, affect the heat exchange efficiency of the heat exchanger, increase the wear of the compressor, and reduce the superheat of the suction air. The quality of the oil return is determined by the oil-gas separator. The oil-gas separation of the existing oil-gas separator often has a large pressure loss, resulting in an increase in the exhaust resistance of the compressor and a corresponding decrease in the energy efficiency o...
