However, the dust filter and the heat exchanger are different in terms of dust accumulation rate, parasitic bacteria, and cleaning methods: the dust accumulation rate of the dust filter is fast, and the dust accumulation rate of the heat exchanger is relatively slow due to the protection of the dust filter; Parasitic dust mites and bacteria mixed in the air dust, in addition to these bacteria on

Embodiment Construction

[0029] The principles and features of the present invention are described below in conjunction with the accompanying drawings, and the examples given are only used to explain the present invention, and are not intended to limit the scope of the present invention.

[0030] The air duct design of the split wall-mounted air conditioner is that the air first passes through the dust filter at the air inlet end, then passes through the heat exchanger, and finally enters the wind wheel cavity. Based on this structure, the individual degree of dirtiness of the heat exchanger can be obtained according to the overall degree of dirtiness of the indoor unit of the air conditioner, that is, the overall degree of dirtiness of the heat exchanger and the dust filter, and the degree of dirtiness of the individual dust filter.

[0031] The air-conditioning heat exchanger dirty clogging detection method based on fan power of the present invention comprises the following steps:

Abstract

The invention relates to a method and system for detecting filth blockage of an air-conditioner heat exchanger based on fan power and an air conditioner. The method includes the following steps of obtaining the filth blockage degree of a dust filtering net at a first fan rotating speed; obtaining first fan power corresponding to the filth blockage degree of the dust filtering net at the first fan rotating speed; obtaining second fan power corresponding to the overall filth blockage degree of an indoor unit at the first fan rotating speed; generating the fan power variation; obtaining the filth blockage level, corresponding to the fan power variation, of the heat exchanger at the first fan rotating speed. The detecting method is simple, the detecting result is accurate, the filth blockage conditions of the dust filtering net and the heat exchanger can be detected at the same time, and the air conditioner can be independently controlled accordingly (for example, the dust filtering net or the heat exchanger is cleaned in a corresponding cleaning mode at different moments); in addition, different control modes can be adopted for the air conditioner according to the different filth blockage levels of the heat exchanger, the functions of the air conditioner are enriched, and the user use satisfaction degree is increased.
