Detailed description of the invention
It should be appreciated that specific embodiment described herein, only in order to explain the present invention, is not intended to limit the present invention.
The present invention provides a kind of air-conditioner, humidification control device and humidity control method thereof, according to current indoor environment temperature Degree and current indoor air humidity calculate existing dew point temperature, and compare existing dew point temperature with described room wall surface temperature Relatively, then operate according to corresponding humidification or the stopping humidification etc. of performing of comparative result.Therefore, the present invention can when needs humidify Humidify, be so possible to prevent wall to produce condensation, thus improve Consumer's Experience.
With reference to Fig. 1, in one embodiment, described humidity control method comprises the following steps:
Step S10, detection current indoor environment temperature and current indoor air humidity, and according to described current indoor environment Temperature and current indoor air humidity calculate dew-point temperature;
In the present embodiment, current indoor environment temperature and current indoor air humidity, can be by humidification control device or set Put the temperature sensor on air conditioner room unit and humidity sensor detects, power at humidification control device or air-conditioner After startup, detect current indoor environment temperature and current indoor air humidity in real time or regularly, with according to current indoor environment temperature Degree and current indoor air humidity calculate and obtain existing dew point temperature.
Dew-point temperature refer to air under the conditions of moisture content and air pressure are all immovable, temperature when being cooled to saturated.When So, in other embodiments, described dew-point temperature can also directly be detected acquisition by dew point temperature sensor.
It should be appreciated that humidification control device can be integrated in air-conditioner, can also be independent of outside air-conditioner And realize coordinated signals between described air-conditioner, when outside humidification control device is independently located at air-conditioner, can be humidifier.With Lower embodiment illustrates as a example by humidification control device is integrated in air-conditioner.
Step S20, obtains room wall surface temperature;
In the present embodiment, described room wall surface temperature include the objects such as room wall, floor, ceiling mean temperature or The minimum of a value chosen, certainly, the acquisition of the temperature value of each object such as described room wall, ground, ceiling, air-conditioning can be taken The infrared sensor of device in the angle of visual field with the mean value of multiple temperature values of predetermined period such as 3 cycle interscans;All right It is associated formula matching meter by parameters such as the compressor operating frequency of air-conditioner, operation time and current outdoor environment temperatures Obtain.
Step S30, when described existing dew point temperature is less than described room wall surface temperature and meets humidified condition, adds Wet process.
In the present embodiment, after being calculated dew-point temperature and room wall surface temperature, air-conditioner can also judge When currently meeting humidified condition, then compare the size of existing dew point temperature and room wall surface temperature further, with according to comparing knot Fruit determines whether to continue humidification.When air-conditioner judges existing dew point temperature less than room wall surface temperature, then carry out humidification process; If existing dew point temperature is more than or equal to room wall surface temperature, if then showing, now continuing humidification can cause wall to occur that condensation is existing As therefore, it is necessary to stop wet operations in time;After air-conditioner stops wet operations certain time, if air-conditioner judges to work as Front dew-point temperature is less than room wall surface temperature, then can re-start wet operations.So, by using the side being interrupted humidification Formula is possible not only to reduce the humidification operation time, is also prevented from humidifying the wall causing for a long time due to air-conditioner and produces asking of condensation Topic.
The humidity control method that the present invention provides, by detection current indoor environment temperature and current indoor air humidity, And calculate existing dew point temperature according to described current indoor environment temperature and current indoor air humidity, getting room wall During temperature, the relatively size between described existing dew point temperature and described room wall surface temperature is little in described existing dew point temperature In described room wall surface temperature and when meeting humidified condition, carry out humidification process.So, the present invention can when needs humidify Humidify, be so possible to prevent wall to produce condensation, thus improve Consumer's Experience.
In one embodiment, as in figure 2 it is shown, on the basis of shown in above-mentioned Fig. 1, described step S20 includes:
Step S201, obtains room wall temperature and room floors temperature;
