Description

Air conditioner filter screen blockage determination method and related equipment Technical Field The application relates to the technical field of air conditioners, in particular to a method for determining blockage of an air conditioner filter screen and related equipment. Background As a core device for adjusting the temperature and humidity of indoor environments, air conditioners are deeply integrated into families, offices and various public places, and become a necessity for improving the comfort level of life and work. However, during long-term operation, the filter screen blockage can gradually affect the equipment performance and the use safety. When the air conditioner works, indoor air is driven to form circulating air flow, and when the circulating air passes through the filter screen in the air conditioner, granular impurities such as dust, hair, cotton wool and the like suspended in the air are intercepted by the filter screen and gradually adhered to the surface of the filter screen. As the time of use increases, these impurities accumulate, which can cause the filter pores to become plugged. The filter screen blockage can directly increase the air circulation resistance, so that the air output of the air conditioner is obviously reduced, the heating or refrigerating efficiency of the air conditioner is further weakened, the time for reaching the set temperature can be prolonged, and the energy consumption of equipment can be increased. And the surface of the blocked filter screen is extremely easy to be attached with microorganisms such as bacteria, mould and the like. The harmful microorganisms can be diffused into indoor air along with the air supply of the air conditioner, and after being inhaled by a human body, the harmful microorganisms can cause health problems such as discomfort and allergy of respiratory tract, and especially threatens the population with weak immunity such as the old and children.
