Abstract

The invention discloses a fault self-checking method of an air conditioner and the multi-split air conditioner. The method is applied to the multi-split air conditioner comprising at least one outdoorunit, multiple indoor units and a controller. The method includes the following steps that the air conditioner is controlled to enter a self-checking mode; when the self-checking mode refers to refrigeration self-checking, whether the air conditioner has a fluorine deficiency fault is judged on the basis of the temperature of a first indoor unit liquid pipe, the temperature of a second indoor unit liquid pipe and the temperature of an outdoor unit coil pipe of the air conditioner, and when the air conditioner does not have the fluorine deficiency fault, fault self-checking is conducted according to first operation parameters and first preset parameters; and when the self-checking mode refers to heating self-checking, fault self-checking is conducted according to second operation parameters and second preset parameters, so that fault self-checking of the air conditioner is achieved, and the self-checking accuracy and efficiency are improved.

Description

technical field [0001] The present application relates to the field of air conditioner control, and more specifically, relates to an air conditioner self-inspection method and a multi-connected air conditioner. Background technique [0002] At present, as people's demand for the aesthetics and comfort of the living environment continues to rise, the number of room air conditioners is increasing day by day. Multi-connected air conditioners are ushering in explosive growth in the domestic market due to their beautiful installation and flexible control. However, the multi-connected air conditioner is more complicated to install than the traditional one-drag-one air conditioner. Especially in the real estate supporting and other tooling projects, there are often irregular installation phenomena such as leaking shut-off valves and low refrigerant charge, which cause the unit to run in abnormal working conditions for a long time. It will affect the user's use effect, and even dama...
