Problems solved by technology

Its working principle is: under the action of the fan, the indoor air that needs temperature regulation enters the air conditioner through the suction grille and the air filter, exchanges heat with the heat exchanger (heat absorption, heat release), and then discharges from the grille. It is discharged into the room, and this reciprocating cycle makes the room achieve cooling or heating, but because the air reciprocates in the air conditioner, the dust, fluff fibers and other debris in the air continue to accumulate and precipitate on the filter screen, thereby increasing the circulation resistance. Large, high power consumption rate, low energy utilization rate, low air conditioner efficiency
The traditional way to solve this problem is to remove and clean the air conditioner regularly regardless of the frequency an

Description

technical field [0001] The invention relates to the technical field of air conditioning, and more specifically relates to an air conditioner filter detection reminder maintenance device and method which are installed on the air conditioner filter to automatically detect its cleanliness and can issue sound and light alarms and display inspection results. Background technique [0002] Existing air conditioners are generally composed of an air suction grill installed on the casing panel, an air filter installed in the suction grill, an indoor and outdoor heat exchanger installed in the filter to evaporate or condense the refrigerant, and a compressor for compressing the refrigerant. Composed of compressor, expansion valve, gas-liquid separator, suction and discharge fans and discharge grille. Its working principle is: under the action of the fan, the indoor air that needs temperature regulation enters the air conditioner through the suction grille and the air filter, exchanges ...
