Abstract

The invention provides a control method for an air conditioner indoor unit and the air conditioner indoor unit. The air conditioner indoor unit includes an indoor heat exchanger and a fresh air device leading the outdoor air to the upstream of the indoor heat exchanger. The control method includes: obtaining the air humidity of the outdoor environment; judging whether the air humidity is greater than or equal to a preset humidity threshold; and turning on the fresh air device when the air humidity is greater than or equal to the preset humidity threshold and the indoor heat exchanger is in a cooling state. When the humidity of the outdoor air exceeds the threshold, the present invention only turns on the fresh air device when the indoor heat exchanger is in a cooling state, and can dehumidify the outdoor air through the indoor heat exchanger, avoiding user discomfort caused by high indoor environment humidity.

Description

technical field [0001] The invention relates to the field of air conditioning, in particular to a control method for an air conditioner indoor unit and the air conditioner indoor unit. Background technique [0002] In order to avoid air quality problems such as high carbon dioxide concentration caused by poor ventilation in the indoor environment, a fresh air device connected to the outdoor environment is usually added in the indoor unit to introduce outdoor air into the indoor environment. However, the current air-conditioning indoor units with fresh air devices have technical problems such as the temperature difference between the outdoor air temperature and the body temperature, which causes discomfort to users, the technical problem that it is always on all year round and consumes power, and the technical problem that the outdoor environment humidity is too high causes user discomfort. . Contents of the invention [0003] An object of the first aspect of the present i...
