Kind Code:
A1
Abstract:
The present application provides an indoor unit filter screen detection method, an indoor unit, an air conditioner, and a readable storage medium. The indoor unit filter screen detection method comprises: obtaining a first resistance difference value of a filter screen under a set air volume value; determining a first outlet static pressure value during the operation of the indoor unit; and determining the filth blockage condition of the filter screen according to a numerical relationship between the first outlet static pressure value and a set outlet static pressure value, and the first resistance difference value. In the present application, the filth blockage condition of the filter screen is detected according to the numerical relationship between the first resistance difference value of the filter screen, and the first outlet static pressure value and the set outlet static pressure value, such that the filth blockage condition of the filter screen can be determined in time during the operation of the indoor unit.
