Abstract

The invention provides an air conditioner. The air conditioner comprises an outdoor unit (1), an indoor unit (2) and a refrigerant pipeline (3) connected between the outdoor unit (1) and the indoor unit (2). The refrigerant pipeline (3) comprises a first pipeline part (31) located in the indoor position and a second pipeline part (32) located on the outdoor position, and a first refrigerant filling nozzle (41) capable of carrying out vacuumizing or refrigerant filling on the refrigerant pipeline (3) is arranged on the first pipeline part (31); and/or, a connecting pipe (5) is further connectedto the second pipeline part (32), one end of the connecting pipe (5) can communicate with the interior of the refrigerant pipeline (3), and the other end of the connecting pipe (5) extends into the indoor position and is connected with a second refrigerant filling nozzle (42) capable of carrying out vacuumizing or refrigerant filling on the refrigerant pipeline (3). By means of the air conditioner, vacuumizing and refrigerant filling can be carried out on an air conditioner system on the indoor side, mounting and maintenance is simpler and more convenient, and the safety coefficient is improved.

Description

technical field [0001] The invention belongs to the technical field of air conditioners, and in particular relates to an air conditioner. Background technique [0002] At present, with the improvement of people's consumption level, air conditioners are used more and more widely. Some air conditioners are installed on high-rise buildings, and the external unit is outside the high-rise buildings. It is very inconvenient to evacuate the outside of the outdoor, and it is also very inconvenient to refill the refrigerant during after-sales maintenance. It is also very dangerous for the installation or maintenance master to operate, the safety factor is very low, and the installation efficiency is also low. [0003] Because the air conditioner in the prior art has technical problems such as inconvenient operation during maintenance, low safety factor, and low maintenance and installation efficiency, the present invention researches and designs an air conditioner. Contents of the ...
