Problems solved by technology
[0002] With the increase of the use time of the air conditioner, the filter screen of the air conditioner will inevitably become dirty and blocked due to the accumulation of dust or sundries. When the filter screen of the air conditioner is seriously dirty and blocked, the heat exchange efficiency of the air conditioner may be poor. and poor ventilation, causing the air volume of the air conditioner to decrease significantly, which in turn leads to a decrease in the heat transfer performance of the air conditioner, which will affect the user's comfort
At the same time, the heat transfer performance of the air conditioner will waste electricity and reduce the service life of fans and compressors.
[0003] At present, the installation position of the air conditioner is usually relatively high, which is not conducive to manually checking whether the air conditioner is dirty and clogged. As a result, users tend to ignore the problem of dirty clogging of the indoor unit of the air conditioner, and cannot clean the filter screen of the indoor unit of the air conditioner in time, which leads to increase and decrease in user comfort

Embodiment Construction
[0064] 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.
[0065] It should be noted that in the following description, the use of suffixes such as "module", "component" or "unit" used to represent elements is only for facilitating the description of the present invention, and has no specific meaning in itself. Therefore, 'module', 'part' or 'unit' may be used in combination. In addition, "plurality" means one or more than one.
[0066] Such as figure 1 As shown, a dirty clogging detection method of an air conditioner filter according to an embodiment of the present invention includes the following steps:
[0067] S10: Obtain evaporator parameters, environment parameters, and outlet and return air parameters of the air conditioner.
[0068] S20: Determine an equivalent dirt thermal resistance a...

The invention provides a method, device, air conditioner and storage medium for detecting dirty and clogged air conditioner filters. The environmental parameters and the air outlet and return air parameters determine the equivalent dirt thermal resistance, and determine whether the filter screen of the air conditioner is dirty or blocked according to the equivalent dirt thermal resistance. The present invention realizes that during the use of the air conditioner, the current operating state of the air conditioner is obtained by acquiring evaporator parameters, environmental parameters, and outlet and return air parameters, and the equivalent dirt thermal resistance of the evaporator under the current operating state is determined according to the current operating state of the air conditioner. It is not necessary to improve the structure of the filter or add a detection device, but to determine whether the air conditioner filter is dirty or blocked according to the equivalent dirt thermal resistance of the evaporator, so as to determine whether to remind the user to clean the air conditioner filter to ensure that the air conditioner is well ventilated and has sufficient The air volume ensures the heat transfer performance of the air conditioner and ensures the user's comfort.
Description
technical field [0001] The invention relates to the technical field of air conditioners, in particular to a method and device for detecting dirty and clogged air conditioner filters, an air conditioner and a storage medium. Background technique [0002] With the increase of the use time of the air conditioner, the filter screen of the air conditioner will inevitably become dirty and blocked due to the accumulation of dust or sundries. When the filter screen of the air conditioner is seriously dirty and blocked, the heat exchange efficiency of the air conditioner may be poor. And poor ventilation, causing the air volume of the air conditioner to decrease significantly, which in turn leads to a decrease in the heat transfer performance of the air conditioner, which will affect the comfort of the user. At the same time, the reduced heat exchange performance of the air conditioner will waste electric energy and reduce the service life of fans and compressors. [0003] At presen...
