WIPO Patent Application WO/2023/226595
Kind Code:
A1
Abstract:
Some embodiments of the present disclosure provide an air conditioning system and a filth blockage determination method for an air conditioning system. The air conditioning system comprises an indoor unit, an outdoor unit, and a controller. The controller is coupled to the indoor unit and the outdoor unit. The controller is configured to: when the air conditioning system is in a heating work state, acquire a first number of detection results within a first duration, wherein the detection results are used for indicating whether filth blockage occurs in the outdoor unit, and the first number is an integer greater than 1; remove a second number of detection results from the first number of detection results to retain a third number of detection results, wherein the acquisition time of the second number of detection results is related to a defrosting operation, the second number is an integer less than the first number and greater than or equal to 0, and the third number is a difference between the first number and the second number; and if the ratio of the number of detection results indicating that filth blockage occurs in the outdoor unit among the third number of detection results to the third number is greater than a first preset threshold, determine that filth blockage occurs in the outdoor unit.
