Problems solved by technology
However, when the air conditioner is used in different environments, the impurity content in the outdoor air is different, and the pollution of the filter device is also different. The following two situations will occur: at the preset time point, the filter device may not need to be cleaned but still When the preset time is not reached, the pollution degree of the filter device is already very serious but has not been cleaned, resulting in low heat exchange efficiency of the air conditioner
[0005] In summary, how to solve the waste of manpower and material resources when cleaning the filter device of the air conditioner, and the problem of low heat exchange efficiency of the air conditioner has become a major technical problem to be solved urgently by those skilled in the art

example 1
[0058] Example 1: When the air conditioner system is running refrigeration at an ambient temperature of 35°C, the air conditioner system will make the following judgments:
[0059] 1. First judge whether the system is running normally: Under normal circumstances, when the ambient temperature is 35°C, the high pressure of the system is about 30kgf, the low pressure of the system is about 8kgf, and the exhaust temperature of the compressor is around 80°C. If the operating parameters of the system are This reasonable range (system high pressure range is 30±5kgf, preferably 30±3kgf; system low pressure range is 8±2kgf, preferably 8±1kgf; exhaust temperature range is 80±15°C, preferably 80±10°C ), it can be determined that the air conditioner system is operating normally;
[0060] 2. Secondly, judge the heat exchange condition of the indoor unit according to the combination of the air inlet temperature and the air outlet temperature of the indoor unit: when the pollution of the fil...

The invention discloses a cleaning reminding method for an air conditioner filtering device. The method comprises the following steps that S1, the air inlet temperature and the air outlet temperature of an indoor unit are collected, and in addition, a different value between the air inlet temperature and the air outlet temperature is calculated; S2, when the different value between the air inlet temperature and the air outlet temperature is greater than a temperature difference preset value, the opening degree of an electronic expansion valve is detected; S3, when the opening degree of the electronic expansion valve is greater than a first opening degree preset value during heating or the opening degree of the electronic expansion valve is smaller than the second opening degree preset value during refrigeration, warning is carried out. The cleaning reminding method for the air conditioner filtering device disclosed by the invention has the advantages that the cleaning can be carried out according to the actual work condition of the filtering device, further, the labor and material waste caused by regular cleaning can be relieved, meanwhile, the filtering device can be cleaned in time, and the heat exchange efficiency of an air conditioner can be ensured. The invention also discloses a cleaning reminding device for the air conditioner filtering device adopting the cleaning reminding method.
Description
technical field [0001] The invention relates to the technical field of air conditioners, in particular to a cleaning reminder method for an air conditioner filter device. The invention also relates to a cleaning reminding device for an air conditioner filter device. Background technique [0002] As the research on the performance of air conditioners continues to mature, the more advanced air conditioners are connected to the return air outlet on the outdoor side, so that the air from the outdoor side is introduced into the indoor side, thereby providing a healthy air environment for the room. This kind of air conditioner can not only realize the temperature adjustment of the indoor air, but also can purify the indoor air, so its application range is constantly expanding. [0003] Since the outdoor air contains more particles and other impurities, in order to ensure the cleanness of the indoor environment, a filter device is usually installed on the indoor side of the air co...
