Abstract

The invention discloses an air conditioner and a detection method and device of the air conditioner. The detection method of the air conditioner comprises the steps that the air conditioner is initialized to enable the air conditioner to be in a commissioning and operating state; a first parameter value is obtained; whether the first parameter value rises to a first preset value within first preset time or not is judged; when the first parameter value rises to the first preset value within the first preset time, a compressor of the air conditioner is controlled to stop operating, and whether the first parameter value reduces to a second preset value within second preset time or not is judged; when the first parameter value does not reduce to the second preset value within the second preset time, the fact that the state of a connecting pipe valve of the air conditioner breaks down is determined. Through the air conditioner and the detection method and device of the air conditioner, the problem that in the prior art, whether the state of the connecting pipe valve of the air conditioner breaks down or not is hard to accurately detect is solved, and the effect of improving the detection precision of the state of the connecting pipe valve is achieved.

Description

technical field [0001] The invention relates to the field of air conditioners, in particular to an air conditioner and a detection method and device thereof. Background technique [0002] In the process of engineering commissioning and installation of air conditioners, especially split-type air conditioners, the last step of engineering installation is to open the valves (including liquid pipe valves and gas pipe valves) of the connecting pipes between internal and external units. If the pipe valve is not opened at all, or if the air conditioner is started to run only when it is not opened, it will cause abnormal operation of the air conditioner. If it is serious, it will cause permanent damage to the air conditioner. Among them, if the air conditioner breaks down in the normal operation state, it will trigger the abnormal protection of the air conditioner. The abnormal protection includes the protection of the system pressure is too high, the system pressure is too low, th...
