Embodiment Construction
[0046] In order to make the above objects, features and advantages of the present invention more comprehensible, specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.
[0047] see figure 1 The embodiment of the present invention provides a method for judging blockage of air conditioner pipeline components, which is applied to an air conditioner, and the air conditioner may be a one-to-one air conditioner, or a multi-connected air conditioner unit. The method for judging the clogging of pipeline components of an air conditioner is used for judging the clogging of pipeline components of an air conditioner, and can improve the accuracy of judging the clogging of pipeline components. The method for judging the blockage of air conditioner pipeline components may include the following steps:
[0048] In step S100, it is determined that the air conditioner has been shut down for a preset cooling time.
[0049]...

Embodiments of the present invention provide a method and device for judging blockage of pipeline components of an air conditioner, and an air conditioner, and relate to the technical field of air conditioners. The method includes: when the air conditioner is in cooling operation and low pressure protection in the first judging period, if the first high and low pressure parameter set satisfies the first preset condition, then controlling the air conditioner to restart and enter the second judging period. When the air conditioner is in cooling operation and low pressure protection in the second judging cycle, if the second high and low pressure parameter set satisfies the second preset condition, the air conditioner is controlled and enters the third judging cycle. When the air conditioner is in the cooling operation of the third judging cycle, if the third high and low pressure parameter group satisfies the third preset condition, the difference between the inlet pipe temperature, middle pipe temperature, outlet pipe temperature and indoor ambient temperature of the indoor unit The value and the opening of the electronic expansion valve determine whether the air conditioner pipeline components are blocked. The method can determine whether the pipeline components are blocked, and improves the accuracy of judging the pipeline components.
Description
technical field [0001] The invention relates to the technical field of air conditioners, in particular to a method and device for judging blockage of pipeline components of an air conditioner and an air conditioner. Background technique [0002] With the improvement of people's living standards, the utilization rate of air conditioners continues to increase, especially multi-connected air conditioners are more and more popular with users. However, impurities will be produced during the production and use of air conditioners, which will cause the air conditioning pipelines or components to be easily blocked after long-term use, the cooling and heating effect of the air conditioner is not good, and the protection cannot operate normally. If the user continues to use the air conditioner in an abnormal state, it will affect the life of the air conditioner; and the pipeline or components are blocked and it is difficult to eliminate the problem after sale. In the related art, the...
