Technical Field
The invention relates to the technical field of air conditioner dehumidification, in particular to an integral air conditioner constant-temperature dehumidification refrigeration cycle system.
Background
The air conditioner is basically popularized in China, and the current air conditioner has a dehumidifying function, but the dehumidifying mode is not essentially different from an air conditioner refrigerating mode, and the dehumidifying function is realized by controlling the inner fan to operate at a rotation speed slightly lower than rated refrigerating according to the room temperature. The disadvantage of this dehumidification mode is: the air outlet temperature is lower during the dehumidification operation, and the room temperature is obviously reduced during the dehumidification. The lack of humidity indication and the control of the reduction in room temperature and the low supply air temperature of the air conditioner can give uncomfortable feeling to the user and even lead to cold and illness. In addition, the room temperature is further reduced, and if the hot and humid air outside the hot and humid weather enters the room, the water is more likely to condense and wet, so that a damp and malignant cycle is formed. Although some dehumidification modes are made up by intermittent start-up and shut-down, this problem has not been fundamentally ameliorated.
