Technical Field

The invention relates to an air conditioner component, in particular to a gas-liquid separator, and specifically relates to an improved gas-liquid separator.

Background

When the refrigerating system operates, lubricating oil is a necessary condition for ensuring the normal and reliable operation of the compressor, and when the system operates, the lubricating oil enters the pipeline along with the exhaust of the compressor and then returns to the gas-liquid separator after circulating flow. The gas-liquid separator mainly plays a role in separating gaseous refrigerants and liquid refrigerants, ensures that the refrigerants entering the compressor are the gaseous refrigerants, prevents liquid impact of the compressor, and meanwhile, the gas-liquid separator plays a role in returning lubricating oil to the compressor.

At present, an outlet pipe of a conventional gas-liquid separator is provided with an oil return hole, and lubricating oil can permeate into the outlet pipe and flow back to a compressor. However, the design is passive oil return, cannot be adjusted according to the requirements of the unit, and is difficult to meet the requirements of modern air conditioning units. Especially, when a plurality of outdoor units are connected in parallel, the problem of uneven oil return is easily caused, and the normal influence of the unit is influenced.

Disclosure of Invention

The invention aims to provide an improved gas-liquid separator aiming at the defects of the prior art, which can realize active oil return, effectively meet the requirement of balanced oil return under the condition that a plurality of outdoor units are connected in parallel and ensure the normal operation of a unit.

The technical scheme of the invention is as follows:

An improved gas-liquid separator comprises a shell, wherein an upper end cover of the shell is provided with an inlet pipe and an outlet pipe; the inlet pipe and the outlet pipe both extend into the upper part of the interior of the shell; a first oil return port and a second oil return port are respectively formed in the lower end cover of the shell and the lower part of the side wall; the first oil return port and the second oil return port are communicated to the outlet pipe through oil return pipes respectively; and the oil return pipe is provided with an electromagnetic valve capable of controlling the on-off of the pipeline.

Furthermore, the solenoid valve is one, and is arranged at the joint of the oil return pipe and the outlet pipe.

furthermore, the number of the electromagnetic valves is two, and the two electromagnetic valves are respectively arranged at the joint of the oil return pipe and the first oil return port or the second oil return port.

Further, the first oil return port is located at the lowest point of the lower end cover; the volume of the shell below the second oil return port is equivalent to the theoretical lubricating oil amount of the single outdoor unit.

The invention has the beneficial effects that:

The invention has reasonable design, simple structure and convenient use, can realize active oil return, effectively meets the requirement of balanced oil return under the condition that a plurality of outdoor units are connected in parallel, and ensures the normal operation of the unit.
