Abstract

The invention provides a leak detection method of an air conditioner indoor unit. One port of a refrigerant pipe of an evaporator of the air conditioner indoor unit is provided with a self-sealing valve, and the other port is provided with a sealing head. The leak detection method comprises a refrigerant leak detection mode. The refrigerant leak detection mode involves injecting a refrigerant into the evaporator through the self-sealing valve and then carrying out leak detection operation on the refrigerant pipe of the evaporator by use of a refrigerant leak detector. According to the invention, the refrigerant is injected into the evaporator and then leak detection is performed on the evaporator by use of the refrigerant leak detector such that correlation devices such as a helium detection vacuum chamber, a helium storage device and the like are omitted, the equipment investment is reduced, operators can perform the leak detection on the evaporator conveniently through the refrigerant leak detector, the evaporator does not have to be placed into the helium detection vacuum chamber for the leak detection, the leak detection process is simplified, and the efficiency is improved.

Description

technical field [0001] The invention relates to air-conditioning equipment, in particular to a leak detection method for an air-conditioning indoor unit. Background technique [0002] At present, the air conditioner is widely used in people's daily life. The air conditioner is divided into an indoor unit and an outdoor unit. The indoor unit is provided with an evaporator, and the outdoor unit is provided with a condenser. After the air conditioner leaves the factory, the condenser of the outdoor unit is filled with refrigerant (freon), but the evaporator of the indoor unit is not filled with refrigerant. In the actual production process, after the evaporator is processed, it is necessary to perform leak detection on the evaporator to determine whether the evaporator will leak the refrigerant. In the prior art, the leak detection technology for the evaporator is as follows: the refrigerant pipe of the evaporator is connected with a quick joint, and helium gas of a certain pr...
