CROSS-REFERENCE TO RELATED APPLICATION

This application claims priority to Taiwanese Patent Application No. 105128020 filed Aug. 31, 2016, the disclosure of which is hereby incorporated in its entirety by reference.

FIELD OF THE INVENTION

BACKGROUND OF THE INVENTION

The higher the temperature is, the greater amount of water vapor in the air will be. In medicine, respiration is closely related to humidity. A relative humidity in a range from 40 to 60% will help oxygen to be easier to enter the human blood through alveoli, and thus it makes people feel most comfortable. On the contrary, when temperature and humidity of the environment become higher, the perspiration system of human being, which regulates human's temperature, becomes affected to thus make people feel muggy and uncomfortable. Therefore, a dehumidifier is widely used by people to regulate the humidity.

A conventional dehumidifier is configured to perform a dehumidifying process according to a preset value of target humidity. The conventional dehumidifier stops the dehumidifying process when the relative humidity reaches the preset value of target humidity. However, since the preset value of target humidity in the conventional dehumidifier is always a constant value which can not be auto-adjusted corresponding to the current environment temperature, the conventional dehumidifier is not an ideal device to provide people with the most appropriate humidity.

 DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

The preferred embodiments of the present invention are described in detail below with reference to FIG. 1 to FIG. 10. The description is used for explaining the embodiments of the present invention only, but not for limiting the scope of the claims.

As shown in FIG. 1 to FIG. 3, a temperature-based adaptive dehumidification system 100 according to one embodiment of the present invention is disposed in an air-conditioning environment (not shown), such as a bedroom, a bathroom, a living room, an office or other environment. The temperature-based adaptive dehumidification system 100 includes a temperature sensing device 1, a humidity sensing device 2 and a dehumidifying device 3.

The temperature sensing device 1 is provided to sense temperature of the air-conditioning environment to obtain environmental temperature information S1. The humidity sensing device 2 is provided to sense humidity of the air-conditioning environment to obtain environmental humidity information S2. The dehumidifying device 3 includes a hygroscopic wheel 31, a heater 32 and a controller 33. The hygroscopic wheel 31 is in air communication with the air-conditioning environment to absorb moisture therefrom. The heater 32 is in thermal connection with the hygroscopic wheel 31 to heat moisture absorbed by the hygroscopic wheel 31 so as to evaporate moisture from the hygroscopic wheel 31. The controller 33 is electrically connected to the temperature sensing device 1, the humidity sensing device 1 and the heater 32 in such a manner that the controller 33 obtains a referenced humidity range which corresponds to the obtained environmental temperature information S1 by means of a calculation in reference to a predetermined reference relationship of temperature-humidity (as shown in FIG. 3), and then the controller 33 performs a comparison between the obtained environmental humidity information S2 and the referenced humidity range thereby, when the obtained environmental humidity information S2 is not within the referenced humidity range, enabling dehumidifying device 3 to perform a dehumidifying process for the air-conditioning environment. Preferably, the hygroscopic wheel 31 is porous and can achieve a good moisture absorption result. For example, the hygroscopic wheel 31 is made of a moisture absorbing material such as zeolite, silica gel, activated alumina or activated carbon. Specifically, the dehumidifying device 3 further includes a motor 34 electrically connected to the controller 33. The motor 34 drives the hygroscopic wheel 31 to rotate when the heater 32 is performing a heating operation.

As shown in FIG. 3, the controller 33 is configured to, when the obtained environmental humidity information is within the referenced humidity range, not perform the dehumidifying process. For example, when the temperature of the air-conditioning environment is 24.5° C. and the humidity of the air-conditioning environment is 35%, the controller 33 obtains a referenced humidity range of 0% to 40% according to the reference relationship of temperature-humidity and thereby determines that the environmental humidity information is within the referenced humidity range, and accordingly does not activate the motor 34 so as to stop the rotation of the hygroscopic wheel 31 and does not activate the heater 31 so as not to heat the hygroscopic wheel 31. When the temperature of the air-conditioning environment is 15° C. and the humidity of the air-conditioning environment is 55%, the controller 33 obtains a referenced humidity range of 0% to 60% according to the reference relationship of temperature-humidity and thereby determines that the environmental humidity information is within the referenced humidity range, and accordingly does not activate the motor 34 so as to stop the rotation of the hygroscopic wheel 31 and does not activate the heater 31 so as not to heat the hygroscopic wheel 31.
