The invention relates to the technical field of dehumidification of a household air conditioner, in particular to a control method and device for comfortable dehumidification of the household air conditioner.
Background
Along with the improvement of living standard of people, the requirements of users on the comfort and the health of the air conditioner are higher and higher, the traditional air conditioner cannot give consideration to both temperature and humidity in the refrigerating operation process, and a large amount of bacteria can be bred in a proper temperature and humidity range; and bacteria can enter a room along with the air supply of the indoor unit, so that certain influence is caused on the health and comfort experience of a user.
Meanwhile, in the actual refrigeration and dehumidification operation of the common household air conditioner, when the room temperature is far higher than the set temperature, the compressor operates at high frequency, the temperature of the coil pipe of the indoor unit is generally low, when the temperature is lower than the dew point temperature of the corresponding ambient air, water vapor in the air can be continuously condensed, condensed water is discharged out of a room from a drain pipe, when the room temperature reaches the set temperature, the relative humidity in the room can be very low, and at the moment, a user can feel uncomfortable to dry; when the room temperature and the set temperature are smaller in difference, most of the air conditioners run at low frequency, at the moment, when the temperature of the coil pipe of the indoor unit is higher than the dew point temperature of corresponding air, water vapor in the air cannot be condensed, when the indoor temperature is reduced to the set temperature, the relative humidity in the room air is possibly higher, and a user can feel oppression and discomfort.
The existing common dehumidification control method basically takes the temperature of an inner disc as a control condition, when the temperature condition of the inner disc is set to be high, the inner disc cannot fully dehumidify, and when the temperature condition of the inner disc is set to be low, the inner disc excessively dehumidifies.
