The comfortable and healthy mode is used for representing an operation mode for simultaneously realizing temperature control, health and humidity regulation, namely an operation mode for realizing the comfortable and healthy function of the fresh air conditioner, and the normal control logic operation of the mode comprises, but is not limited to, regulation of indoor environment temperature, regulation of indoor humidity, regulation of air quality, control of fresh air and the like, and can be specifically set according to actual conditions.
Step S104, judging whether the fresh air conditioner executes a ventilation function or not;
specifically, when the fresh air conditioner operates in a comfortable and healthy mode, whether the fresh air conditioner is in a ventilation mode is firstly judged, namely whether the fresh air conditioner performs a ventilation function is firstly judged. In a possible implementation manner, when the fresh air conditioner performs the ventilation function, it is further determined whether the TVOC concentration value meets the health standard, i.e., if the TVOC concentration value is not greater than the preset concentration threshold, the fresh air conditioner is controlled to operate in a comfortable and healthy mode; or if the TVOC concentration value is larger than the preset concentration threshold value, controlling the fresh air conditioner to execute the air exhausting function until the execution duration reaches the second preset duration, and controlling the fresh air conditioner to operate according to the comfortable and healthy mode.

(A2) When the indoor environment temperature meets the temperature control condition, judging whether the continuous operation duration of the compressor reaches a first preset duration, if not, controlling the fresh air conditioner to continue to operate according to the normal control logic of the comfortable and healthy mode, and judging in real time to ensure that the operation frequency of the compressor is kept stable as much as possible until the continuous operation duration of the compressor reaches the first preset duration; the first preset time length is preferably 10min, and can be specifically set according to actual conditions;
(A3) When the indoor environment temperature meets the temperature control condition and the continuous operation time of the compressor reaches a first preset time, at the moment, if the TVOC concentration value is larger than a preset concentration threshold value, controlling the fresh air conditioner to execute an air exhaust function until the execution time reaches a second preset time; and controlling the fresh air conditioner to operate according to a comfortable and healthy mode; i.e. when the TVOC concentration value is more than 0.6mg/m 3 When the air exhausting time is up, the fresh air conditioner is controlled to execute the air exhausting function until the execution time reaches the second preset time for 5min, and the fresh air conditioner is controlled to operate according to the normal control logic of the comfort health mode; if the TVOC concentration value is not greater than the preset concentration threshold value, namely when the TVOC concentration value is less than or equal to 0.6mg/m 3 At this time, the indoor environment temperature and the air quality both meet the comfort health experience of the user, and the air humidity is required to be adjusted in order to further improve the experience of the user;
(A4) When the indoor environment temperature meets the temperature control condition, the continuous operation time of the compressor reaches the first preset time, and the TVOC concentration value is not larger than the preset concentration threshold value, at the moment, the target function adjustment mode is determined according to the relative humidity and the preset humidity threshold value.

When the relative humidity is more than or equal to RH2, controlling the fresh air conditioner to execute an air exhaust function, and increasing the operating frequency of the compressor, for example, the operating frequency of the compressor is increased by 5Hz on the basis of the current operating frequency until the operating frequency is increased to the set highest frequency of the compressor or the frequency is limited to be reduced for protection, the frequency is not increased any more, and simultaneously controlling the compressor to operate for a certain period of time, for example, 5 minutes, according to the increased operating frequency, so that the air exhaust function can lead indoor water vapor to the outside of a room through a second functional mode, on one hand, so as to reduce the indoor humidity; on the other hand, the operation frequency of the compressor can be increased to increase the dehumidification capacity when the fresh air conditioner is used for refrigerating, and the operation frequency of the compressor can be increased to increase the air outlet temperature when the fresh air conditioner is used for heating, so that the relative humidity is reduced. Therefore, the indoor humidity is adjusted in a target function adjustment mode, and the user comfort experience is further improved.
Further, the method further comprises: and if the relative humidity is greater than the first humidity threshold and less than the second humidity threshold, controlling the fresh air conditioner to operate according to the comfortable and healthy mode.
