The present embodiment provides a humidification control method for an air conditioner, which can be applied to a controller of an air conditioner, referring to a flow chart of the humidification control method for an air conditioner shown in fig. 1, the method mainly includes the following steps S102 to S106:
step S102: and judging whether the air conditioner meets the preset humidification control condition or not.
The air conditioner comprises one or more indoor units, and after the air conditioner is started to operate, whether the indoor unit of the air conditioner meets a preset humidification control condition is judged, wherein the humidification control condition can be related to a humidification instruction, indoor humidity or an operation mode, such as when the indoor humidity is low, or when the indoor unit receives a humidification instruction input by a user, or when the indoor unit operates in a heating mode, the air conditioner is determined to meet the preset humidification control condition.
In a specific embodiment, when the indoor unit is in a shutdown state and a humidification instruction is received, it is determined that the indoor unit satisfies a preset humidification control condition. When the indoor unit of the air conditioner is in a shutdown state, if a humidification instruction is received, it is determined that the indoor unit receiving the humidification instruction meets the preset humidification control condition, wherein the humidification instruction can be input by a user through a remote controller or a control panel, or can be triggered when a humidity sensor detects that the indoor humidity is lower than the minimum humidity. When the indoor unit receives the humidification instruction, the indoor unit is determined to meet the preset humidification control, so that the humidification requirement of a user is met, and the condition that the indoor humidity is too low is avoided.
In another specific embodiment, when the indoor unit operates in the heating mode, the indoor unit is controlled to operate from the heating mode to the cooling mode, and when the indoor unit operates in the cooling mode for a second preset time period, it is determined that the preset humidification control condition is met. The value range of the second preset duration can be 5-15 min, and the preferred value is 10 min. When the indoor unit is in a heating mode, if the outdoor environment temperature is lower than 16 ℃, the outdoor environment temperature is lower, the air conditioner is controlled to enter a forced cooling mode to operate, and therefore the indoor unit evaporator can generate more condensation.
And the indoor unit is controlled to be switched to the refrigerating mode to operate by controlling the operation of the indoor unit in the heating mode, and the indoor unit after the second preset time of refrigerating operation meets the preset humidifying control condition so as to control the indoor unit to enter the humidifying mode to operate.
