In order to make object of the present invention, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.
Fig. 1 shows the realization flow of the air-conditioner indoor dehumidification progress control method that the embodiment of the present invention provides, and for convenience of explanation, illustrate only the part relevant to the embodiment of the present invention, details are as follows:
In step sl, judge whether the interior space gets damp again according to indoor temperature, outdoor temperature and outside humidity.
Wherein, as shown in Figure 2, step S1 comprises the following steps:
S11. indoor temperature and outdoor temperature are detected;
S12. outside humidity is detected;
S13. outdoor vapour pressure is obtained according to detected outdoor temperature and outside humidity;
S14. corresponding indoor saturated vapor pressure is obtained according to detected indoor temperature;
S15. judge whether outdoor vapour pressure is greater than indoor saturated vapor pressure, is, then judge that the interior space gets damp again, no, then judge that the interior space gets damp again.
It should be noted that, the dry wet degree of air is relevant with vapour quantity contained in air herein, and the saturated vapor pressure that different temperature is corresponding different (the steam pressure namely during water loading of the air arrival saturation state).Above-mentioned outside humidity refers to the relative humidity percentage of saturation vapour density at identical temperature (water-vapo(u)r density namely in outdoor air contained by reality with) of outdoor air, and judge whether the interior space gets damp again, then need to judge whether outdoor vapour pressure is greater than indoor saturated vapor pressure, if outdoor vapour pressure is greater than indoor saturated vapor pressure, then show that air in the interior space cannot moisture in compartment outer air, just there will be moisture regain thus.
For above-mentioned step S13, its specifically: obtain corresponding outdoor saturated vapor pressure according to detected outdoor temperature, and outdoor saturated vapor pressure and detected outside humidity carried out product calculation to obtain outdoor vapour pressure.In fact outdoor vapour pressure is exactly the steam pressure in the air under current outside humidity.Wherein, the step of corresponding outdoor saturated vapor pressure is obtained according to detected outdoor temperature and step S14 obtains according to the known water saturated vapor pressure table of comparisons at different temperatures.Such as: suppose that outside humidity is 90%, outdoor temperature is 30 degrees Celsius, and the saturated vapor pressure corresponding to it is 4.2425, then outdoor vapour pressure is 90% × 4.2425=3.818; If now indoor temperature is 18 degrees Celsius, the saturated vapor pressure corresponding to it is 2.0644, it can thus be appreciated that 4.2425 are greater than 2.0644, then judges that the interior space gets damp again.In addition, suppose that outside humidity is 55%, outdoor temperature is 26 degrees Celsius, and the saturated vapor pressure corresponding to it is 3.36, then outdoor vapour pressure is 55% × 3.36=1.848; If now indoor temperature is 18 degrees Celsius, the saturated vapor pressure corresponding to it is 2.0644, it can thus be appreciated that 1.848 are less than 2.0644, then judges that the interior space gets damp again.
In step s 2, if judge, the interior space gets damp again, then judge whether the interior space has people.
