Problems solved by technology
However, since most of the new refrigerants are flammable and explosive, there is a risk of explosion after the refrigerant leaks
During the transportation of the outdoor unit, there are factors such as bumpy roads or collisions with the outdoor unit, which may cause the risk of refrigerant leakage. Therefore, transporting the air conditioner filled with refrigerant has certain safety hazards

Embodiment Construction
[0028] The core of the present invention is to provide a method for injecting refrigerant into an air conditioner, so as to reduce the potential safety hazard of the air conditioner using flammable and explosive refrigerants.
[0029] In order to enable those skilled in the art to better understand the solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.
[0030] Please refer to figure 1 As shown, the embodiment of the present invention discloses a method for injecting refrigerant into an air conditioner. The refrigerant is injected into the air conditioner, which includes the following steps:
[0031] Step S1: Vacuumize and maintain pressure on the refrigerant paths of both the indoor unit and the outdoor unit of the air conditioner to obtain a vacuum indoor unit and a vacuum outdoor unit.
[0032] After the indoor unit and the outdoor unit of the air conditioner are ...

The invention provides a method for filling refrigerant into an air conditioner, which is used for filling the refrigerant into the air conditioner. The method comprises the following steps of (1) respectively carrying out vacuum suction and pressure maintaining treatment on refrigerant paths of an indoor unit and an outdoor unit of the air conditioner, so as to obtain the vacuum indoor unit and the vacuum outdoor unit; (2) after transporting, installing the vacuum indoor unit and the vacuum outdoor unit, and communicating the refrigerant paths of the indoor unit and the outdoor unit; (3) filling the refrigerant into the refrigerant path of the installed indoor unit. The method has the advantage that by adopting the process, the refrigerant is not filled when the indoor unit and the outdoor unit are transported, so the possibility of leakage of refrigerant in the transportation process of the air conditioner is avoided, and the safety hidden hazards are avoided.
Description
technical field [0001] The invention relates to the technical field of air conditioners, in particular to a method for injecting refrigerant into an air conditioner. Background technique [0002] Refrigerant, also known as refrigerant, is the working medium of the refrigeration cycle. It uses the phase change of the refrigerant to transfer heat, that is, the refrigerant absorbs heat when it vaporizes in the evaporator, and releases heat when it condenses in the condenser. [0003] Because fluorine-containing refrigerants are destructive to the atmospheric ozone layer, in order to protect the human living environment, it is necessary to reduce the damage to the atmospheric ozone layer to reduce the greenhouse effect. At present, people are beginning to use new refrigerants - hydrocarbons and HFC refrigerants to replace fluorinated refrigerants. [0004] At present, for the injection of refrigerant, the refrigerant is usually injected into the outdoor unit of the air conditio...
