Embodiment Construction
[0036] In order to make the purpose, technical solution and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present application, and are not intended to limit the present application.
[0037] The air conditioner exhaust fault detection method provided in this application can be applied to an air conditioner, and can also be applied to a server electrically connected to the air conditioner or connected to a network. Wherein, the server may be implemented by an independent server or a server cluster composed of multiple servers.
[0038] In one embodiment, such as figure 1 As shown, a method for detecting air-conditioning exhaust faults is provided, and the application of this method to an air-conditioning is taken as an example for illustration, includin...

The present application relates to an air conditioner exhaust fault detection method, device and air conditioner. The method includes: when the air conditioner has an exhaust temperature failure, detecting whether the exhaust temperature sensing package is abnormal: controlling the air conditioner's compressor, indoor fan, and outdoor fan to stop running, opening the expansion valve to the maximum opening, and opening all solenoid valves ;Start timing; when the timing time reaches the first time threshold, detect the external ambient temperature and the temperature of the exhaust temperature sensor; when the difference between the external environment temperature and the temperature of the exhaust temperature sensor is greater than or equal to the first preset value, Then it is judged that the exhaust temperature sensing package of the air conditioner is abnormal. By adopting the method, the fault detection of the air conditioner can be carried out automatically without manual participation, which is very convenient.
Description
technical field [0001] The present application relates to the technical field of air conditioners, in particular to an air conditioner exhaust fault detection method and device, a multi-connected air conditioner and a storage medium. Background technique [0002] As society and the government's awareness of environmental protection increases, multi-split air conditioners, as energy-efficient and easy-to-maintain central air-conditioning products, are increasingly entering the home improvement and tooling markets. Multi-connected units are different from ordinary household air conditioners. The number of internal and external units involved in the system and the control complexity of components are very different, and the maintenance is difficult. Especially the fault cause detection has high requirements for technical maintenance personnel. On-line maintenance and after-sales service bring a big bottleneck problem. [0003] At present, the market's patents on exhaust superh...
