A method for cleaning an air conditioner includes: in response to a cleaning instruction, controlling frosting on the surface of a target heat exchanger; after a frosting completion condition is met, controlling defrosting of the frost on the target heat exchanger; and after a defrosting completion condition is met, reducing the surface temperature of the target heat exchanger to a sterilization temperature, and carrying out quick cooling sterilization, wherein the temperature difference between the sterilization temperature and the defrosting temperature during defrosting meets a set temperature change sterilization condition. By a frosting-defrosting process, dirt such as dust on the heat exchanger may be effectively stripped and deep bacteria may be exposed, and then the quick cooling sterilization process may kill the bacteria by utilizing the sharp temperature change during switching from the defrosting process to the quick cooling process. Also disclosed is the air conditioner.

Method for cleaning air conditioner and air conditioner

A self-cleaning method for an air-conditioner heat exchanger is provided and includes: controlling an air-conditioner to enter a self-cleaning mode; detecting an ambient temperature of a to-be-cleaned heat exchanger, and determining, according to the detected ambient temperature, a target evaporating temperature of the to-be-cleaned heat exchanger; adjusting, according to the target evaporating temperature and an actual evaporating temperature of the to-be-cleaned heat exchanger, an evaporating temperature of the to-be-cleaned heat exchanger, and controlling the to-be-cleaned heat exchanger to frost; and after a surface of the to-be-cleaned heat exchanger is covered with a frost layer or an ice layer, controlling the air conditioner to enter a defrosting mode of the to-be-cleaned heat exchanger.

Air conditioner and method for self-cleaning air conditioner heat exchanger

A method for cleaning an air conditioner indoor unit and outdoor unit includes controlling a heat exchanger to enter a self-cleaning mode, adjusting an operating frequency of an air conditioner, an opening of a throttling device, and a corresponding fan speed of the heat exchanger, and maintaining an evaporating temperature of the heat exchanger within a present range to enable a frost process on a surface of the heat exchanger. When a differential pressure of the air conditioner meets a preset condition, a four-way valve changes a direction, switching defrosting to indoor and outdoor heat exchangers. When the differential pressure does not meet the preset condition, the air conditioner is adjusted to meet the preset condition and the four-way valve direction is changed to perform a defrosting switching to the indoor and outdoor heat exchangers.
