Specifically, indoor environment temperature (i.e. room temperature), envionmental humidity and evaporator tube temperature (i.e. evaporator temperature) can be detected,
Surrounding air dew point temperature can be calculated afterwards according to indoor environment temperature and envionmental humidity.More specifically, can will detect
To indoor environment temperature and envionmental humidity substitute into dew point temperature computing formula in, to obtain dew point temperature.Wherein,
In an embodiment of the present invention, the computing formula of dew point temperature can be:
Td=b/ [a/log (e/6.11)-1] (1)
E=f*Es (2)
Es=E0*10[a*t/(b+t)] (3)
Wherein, Td is the dew point temperature of air, and e is the water vapor pressure of air, and its unit is hpa, and a, b are respectively parameter,
For the water surface (t > 0 DEG C), a=7.5, b=237.3, for ice face (t≤0 DEG C), a=9.5, b=265.5, f are ring

Frequency is constant;If temperature difference is less than the first temperature threshold, then increase running frequency, and repeated execution of steps S102-S104.
Wherein, in an embodiment of the present invention, the first threshold temperature can be 4, it will be understood that this threshold temperature " 4 " is according to big
The empirical value that the test of amount is drawn, has different value in different frequency conversion dehumidifiers, needs the actual performance according to dehumidifier
Preferentially choose.
During more specifically, the temperature difference between dew point temperature and evaporator temperature is more than or equal to the first threshold temperature, permissible
Understand and now can reach the condition that vaporizer can dehumidify, so at this moment the running frequency of frequency-changeable compressor avoids the need for rising,
Frequency-changeable compressor is the most now kept to continue to run with current operation frequency;When said temperature difference is less than the first threshold temperature, can
To understand the condition that vaporizer can dehumidify that is the most also not up to, so at this moment needing to increase the running frequency of frequency-changeable compressor, example
As, current running frequency can be increased a frequency, control frequency-changeable compressor and enter with the running frequency increasing by 1 frequency
Row runs, and after running certain time (such as 2 minutes), repeated execution of steps S102-S104, i.e. continues to obtain to work as
Front room temperature, relative humidity and evaporator temperature, and obtain dew point temperature according to current room temperature and relative humidity, and according to dew
Temperature difference between some temperature and evaporator temperature carries out corresponding control to frequency-changeable compressor.Thus, it is ensured that dehumidifier energy
Enough reach the purpose of dehumidifying.
Further, in one embodiment of the invention, when temperature difference is more than or equal to the first threshold temperature, fortune is kept
After line frequency is constant, in this dehumidifier, the control method of frequency-changeable compressor may also include that running first with running frequency presets
Time;If temperature difference is more than or equal to the second threshold temperature, then reduce running frequency, and repeated execution of steps S102-S104;
If temperature difference is less than the second threshold temperature, then remain on frequency constant.Wherein, in an embodiment of the present invention, second
Threshold temperature can be 6.It is appreciated that this threshold temperature " 6 " is the empirical value drawn according to substantial amounts of test, in difference
Frequency conversion dehumidifier has different value, needs preferentially to choose according to the actual performance of dehumidifier.
Specifically, said temperature difference more than or equal to the first threshold temperature time remain on frequency constant after, control frequency conversion
Compressor runs the first Preset Time (such as 5 minutes) with current running frequency, and is running first with current running frequency
After Preset Time (such as 5 minutes), by the temperature difference between dew point temperature now and evaporator temperature and the second temperature valve
Value compares.When said temperature difference is more than or equal to the second threshold temperature, can illustrate that the dehumidifying effect of now vaporizer is
Having surplus, the ability of frequency-changeable compressor can be lowered, and can frequency reducing run, and repeated execution of steps S102-S104;
When said temperature difference is less than the second threshold temperature, can illustrate that the current operation frequency of now frequency-changeable compressor meets and work as front evaporator
The dehumidifying effect of device, and when the dehumidifying effect of front evaporator not yet has surplus, so now without frequency-changeable compressor is dropped
Frequency controls to reduce compressor operating noise, and the running frequency that need to control frequency-changeable compressor holding current is constant.Thus, can protect
Card frequency-changeable compressor is can to run with low frequency on the premise of dehumidifying meeting vaporizer, thus reduces compressor operating
Noise.
It should be noted that in one embodiment of the invention, the temperature between dew point temperature and evaporator temperature at this moment
Before degree difference is more than or equal to reducing running frequency during the second threshold temperature, can first judge the current operation frequency of frequency-changeable compressor
It is minimum frequency, has run if it is not, then a frequency will be reduced on the basis of current operation frequency;
If it is determined that the current operation frequency of frequency-changeable compressor has been minimum frequency, then can maintain the current operation of frequency-changeable compressor
Frequency.
Further, in one embodiment of the invention, the temperature difference between dew point temperature and evaporator temperature at this moment
Remain on during less than the second threshold temperature frequency constant after, in this dehumidifier, the control method of frequency-changeable compressor may also include that
The second Preset Time, and repeated execution of steps S102-S104 is run with running frequency.Wherein, in an embodiment of the present invention,
Second Preset Time is equal to the first Preset Time.It should be noted that in an embodiment of the present invention, the first Preset Time and
Second Preset Time is all the empirical value drawn by lot of experiments, has different values, need in different dehumidifiers
Actual performance according to dehumidifier preferentially chooses this first Preset Time and the second Preset Time.Should be appreciated that in the present invention
Embodiment in, remaining on, frequency is constant or after increasing frequency or frequency reducing, is running certain time with current operation frequency
Reason is so that value judges again when dehumidifier tends towards stability, to objectively respond room temperature at that time, relative humidity
Situation and mutual relation with evaporator temperature.
Also, it should be noted in one embodiment of the invention, remain on when temperature difference is less than the second threshold temperature
Frequency is constant, and after running the second Preset Time with this running frequency, can detect either with or without the operation receiving switch mode,
If it has, then dehumidifier is by the mode operation of switching, and terminate this quiet operational mode;If it is not, running the
After two Preset Times, continue executing with above-mentioned steps S102, then carry out detecting temperature and humidity and judging, circulate successively
Till exiting quiet operational mode.
The control method of frequency-changeable compressor in dehumidifier according to embodiments of the present invention, can first receive quiet operating instruction, and will
The running frequency of frequency-changeable compressor is set to preset value, can obtain current room temperature, relative humidity and evaporator temperature, and root afterwards
Obtain dew point temperature according to current room temperature and relative humidity, and obtain the temperature difference between evaporator temperature and dew point temperature, and
According to temperature difference, the running frequency of frequency-changeable compressor is controlled, when i.e. meeting different condition according to temperature difference, frequency conversion is compressed
The running frequency of machine carries out increasing frequency or frequency reducing or keeping the operation such as constant so that dehumidifier is guaranteeing the situation of dehumidifying
