Abstract

The invention discloses an outdoor unit, a method for filling lubricating oil into the outdoor unit and an air conditioner, wherein the outdoor unit comprises a compressor, an oil separator, an oil uniform distributing device, a four-way valve and an oil uniform distributing pipe, wherein an exhaust opening of the compressor is communicated with an air inlet of the oil separator, an air outlet of the oil separator is communicated with an inlet of the four-way valve through the oil uniform distributing device, an oil uniform distributing opening of the oil uniform distributing device is communicated with the oil uniform distributing pipe, the outdoor unit also comprises an oil filling device, the oil filling device comprises an oil filling valve and an oil filling pipe, one end of the oil filling pipe is communicated with an outlet of the oil filling valve, and the other end of the oil filling pipe is communicated with the oil uniform distributing pipe. Before the machine unit vacuum pumping, firstly, a tooling containing lubricating oil is connected onto the oil filling valve, the oil filling valve is opened during the vacuum pumping, and the lubricating oil filling can be realized. The oil filling work procedure is carried out in the vacuum pumping link, the lubricating oil addition is not needed before the welding, so the welding risk is reduced, the safety is improved, and in addition, the occurrence of system harm caused by welding slag falling into the oil can also be avoided.

Description

technical field [0001] The invention relates to the field of air conditioning, in particular to an outdoor machine, a method for filling the outdoor machine with lubricating oil, and an air conditioner using the outdoor machine. Background technique [0002] At present, the method of injecting lubricating oil into the air-conditioning system is generally to inject directly into the oil or gas during production and assembly, and then weld the pipeline. This oil injection method has the following defects: because the lubricating oil is flammable, there is a certain risk in the welding process; moreover, welding slag is likely to fall into the oil during welding, which will cause harm to the system. Contents of the invention [0003] In view of the current state of the art above, the technical problem to be solved by the present invention is to provide an outdoor unit that does not need to add lubricating oil before welding, so as to reduce the risk of welding and prevent imp...
