Abstract

The invention provides an air conditioner and an oil return control method and device, and relates to the technical field of air conditioners. The air conditioner comprises a compressor, an oil separator, an oil return pipe assembly and a controller. The compressor is provided with an exhaust pipe used for discharging gas. The exhaust pipe is connected to the oil separator. The oil return pipe assembly is connected with the oil separator and used for storing lubricating oil. The oil return pipe assembly is connected with the compressor and is in one-way communication with the compressor, so that the lubricating oil in the oil return pipe assembly flows to the compressor from the oil return pipe assembly. The controller is electrically connected with the oil return pipe assembly and used for controlling the oil return pipe assembly to be opened according to the increase and decrease amount of the exhaust pressure of the exhaust pipe so as to be in communication with the oil separator or controlling the oil return pipe assembly to be closed. The oil return control method and device are both applied to the air conditioner. By means of the air conditioner and the oil return control method and device, the circumstance that in the prior art, the lubricating oil separated out by the oil separator cannot return to the compressor can be improved.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to an air conditioner, an oil return control method and a device. Background technique [0002] In order to prevent the oil leakage of the external unit of the air conditioner, an oil separator is installed on the exhaust pipe, and the oil separated by the oil separator (hereinafter simply referred to as separated oil) needs to be returned to the compressor. However, in an air conditioner equipped with a high-pressure compressor in which the pressure of the compressor body is close to the discharge pressure, the pressure inside the oil separator will be lower than the pressure of the compressor body due to pressure loss in the discharge pipe. Therefore, if only the oil return pipe is used to connect the oil separator and the compressor body, the separated oil will not return to the compressor. Contents of the invention [0003] The problem solved by the invention is how ...
