Oil separator and air conditioner provided with same

Abstract

The invention provides an oil separator and an air conditioner provided with the same. The oil separator comprises a shell provided with an inner cavity, an inlet formed in the shell, a gas exhaust pipe and an oil outlet. The gas exhaust pipe comprises a gas inlet part, a heat exchange part and a gas outlet part which are sequentially arranged. The gas inlet part and the heat exchange part are arranged in the inner cavity. The heat exchange part is located under the gas inlet part, the gas outlet part penetrates out of the shell, and gas entering from the gas inlet part is used for heating liquid in the shell through the heat exchange part and is exhausted out of the gas outlet part. The oil outlet is formed in the bottom of the shell. By adoption of the technical scheme provided by the invention, the problem that a heating mode of an oil separator in the prior art consumes much energy is effectively solved.

Description

technical field

[0001] The invention relates to the technical field of air-conditioning equipment, in particular to an oil separator and an air conditioner having the same. Background technique

[0002] At present, the oil return control of the compressor generally adopts the scheme of an oil return capillary to control the oil return. However, when the compressor operates at low temperature, due to the increase of lubricating oil flocs in the oil separator, the viscosity increases, which will cause the resistance of the lubricating oil to pass through the oil return capillary to increase, resulting in difficulty in oil return, return Insufficient oil will eventually lead to the lack of oil in the compressor and cause the unit to stop, and even cause damage to the compressor due to severe wear and tear.

[0003] In the prior art, in order to solve the above problems, an electric heating belt is usually arranged at the bottom of the oil separator, and the lubricating oil at ...
