Embodiment Construction
[0029] Specific embodiments of the present invention are described in detail below.
[0030] This embodiment proposes a constant temperature dehumidification air conditioner and its control method.
[0031] see figure 1 , figure 2 As shown, first, the control method of the constant temperature dehumidification air conditioner of this embodiment is described in conjunction with the accompanying drawings:
[0032] When the air conditioner is turned on, when the control unit receives the "constant temperature dehumidification" signal sent by the remote controller, the control unit controls the air conditioner to enter the constant temperature dehumidification mode.
[0033] First, the temperature detection unit detects the indoor ambient temperature Tr, and the control unit determines the set temperature Ts according to the detected indoor ambient temperature Tr.
[0034] Specifically, such as figure 2 As shown, when the air conditioner enters the constant temperature dehum...

The invention relates to a constant-temperature dehumidification air conditioner and a control method thereof. The control method includes: detecting indoor environment temperature Tr, and determining setting temperature Ts according to the indoor environment temperature Tr; timely detecting the indoor environment temperature Tr and comparing the new indoor environment temperature Tr detected with the setting temperature Ts; enabling an air conditioner to be operated in a shutdown dehumidification area, a refrigeration dehumidification area or a reheat dehumidification area. A constant-temperature dehumidification mode is divided into the shutdown dehumidification area, the reheat dehumidification area and the refrigeration dehumidification area through the indoor environment temperature and the setting temperature, so that limitation that only the indoor environment temperature is judged is avoided; through judgment of the indoor environment temperature, the reheat dehumidification area can be partitioned, operation frequency of a compressor can be selected, and situations that room temperature changes due to frequent shutdown of the compressor and reliability of the compressor is lowered can be avoided; through above two comprehensive detection judgment, operation states of parts of the air conditioner can be determined, and more stable indoor temperature and humidity control can be achieved.
Description
technical field [0001] The invention belongs to the technical field of air conditioners, and in particular relates to a control method capable of realizing a constant temperature dehumidification air conditioner. Background technique [0002] The traditional reheat dehumidification air conditioner only judges whether to run the reheat dehumidification mode according to the indoor ambient temperature. This dehumidification mode is single, which not only reduces the indoor ambient humidity during the dehumidification process, but also reduces the indoor ambient temperature, which makes the indoor environment more stable. Comfort is reduced. As the indoor ambient temperature continues to drop, the compressor may even stop. Frequent compressor shutdowns will easily cause room temperature changes and reduce the reliability of the compressor, and the dehumidification effect cannot be achieved. If the indoor ambient temperature is in a boundary condition, such as the minimum cooli...
