X can be between 25 and 27, preferably X can be between 26 and Y can be between 29 and 31, and preferably Y can be between 30.
It should be understood that the above division manner regarding the indoor temperature level is only exemplary, and in practical applications, the division manner is various, and needs to be determined according to practical application situations, and is not limited herein.
103. When the operating frequency reaches a preset frequency, acquiring the average temperature of condensed water in a condensed water storage device of the air conditioner within a preset time;
in the process of starting the air conditioner, the running frequency of a compressor of the air conditioner needs to be monitored, after the air conditioner enters a refrigeration mode, the compressor of the air conditioner cannot reach a preset frequency corresponding to the refrigeration mode immediately, the compressor can experience a period of frequency rise, when the running frequency is monitored to reach the preset frequency, timing is started by taking the current moment as an initial moment, and the average temperature of condensed water in a condensed water storage device of the air conditioner is obtained within a preset time.
104. Determining the indoor environment humidity according to the average temperature, the indoor environment temperature and a preset relative humidity table;
in the embodiment of the application, a humidity sensor is not adopted to detect the indoor environment humidity, in practical application, the humidity sensor is arranged at the air inlet panel, if the humidity sensor needs to be added, a corresponding structure needs to be arranged at the air inlet panel to be matched with the humidity sensor, namely, the humidity sensor needs to be fixed, the humidity sensor is isolated from other parts inside the air conditioner indoor unit, and the overall structure needs to be additionally adjusted for the circuit connection of the humidity sensor, so that the structure of the air conditioner indoor unit becomes complex, the structure of the air conditioner indoor unit is negatively influenced, and the design and the production are not facilitated; meanwhile, the humidity sensor forms shielding at the air inlet panel, so that the air inlet volume passing through the air inlet panel is reduced, and the refrigeration and heating effects of the air conditioner are influenced. Therefore, in the embodiment of the present application, a preset relative humidity table is provided, which determines a mapping relationship among the average temperature of the condensed water, the indoor environment temperature, and the indoor environment humidity, and the mapping relationship is determined based on the experimental test result and a condensation rule, where the condensation rule is that when the indoor environment humidity is higher, the dew point temperature of the current indoor environment is higher, the dew point temperature is the same as the water vapor content in the air, and when the air pressure is kept constant, the air is cooled to reach a temperature at which the air is saturated, the water vapor in the air is more likely to become the condensed water, so that in this case, the more the condensed water in the condensed water storage is, the more the condensed water storage is, the lower the average temperature of the condensed water is.

When the object does not undergo a chemical change or a phase change, the heat required to raise or lower the temperature is called sensible heat, and the required amount of heat is the amount of sensible heat. Sensible heat in the total refrigerating capacity of the air conditioner is used for reducing the dry-bulb temperature of the environment, namely the sensible heat is higher, and the proportion of the sensible heat to the total refrigerating capacity is higher, the cooling rate of the indoor environment is higher, and the refrigerating effect is better. Correspondingly, the latent heat is used for condensing moisture in the ambient air, i.e. the higher the latent heat, the higher the proportion of the total cooling capacity, the faster the air moisture of the indoor environment condenses and the lower the air humidity.
The ratio of the latent heat in the total refrigerating capacity is controlled to control the condensing speed of the water vapor, so that the air conditioner can achieve the effects of adjusting the indoor environment humidity and the indoor environment temperature, and the temperature and the humidity of the indoor environment reach the level suitable for human body activities.
