Service time carries out timing, and reaches the 3rd preset time and indoor environment relative humidity calculation in the service time of magnetic valve 6
Value is more than or equal to the indoor environment relative humidity detected, and control magnetic valve 6 is closed, and window-mounted air conditioner system is exited anti-condensation fortune
Row mode.Wherein, the 3rd preset time can be demarcated according to actual conditions.For example, the 3rd preset time can be 20 points
Clock.
According to the specific example of the present invention, on the basis of water capacity 17.7g/kg in air, when window-mounted air conditioner system
When starting refrigerating operaton, the run time of start recording compressor 2, when the run time of compressor 2 reaches the second preset time
During such as 5 minutes, temperature detecting module 100 detects indoor environment temperature TA, while humidity detecting module 200 detects indoor environment phase
To humidity HA, control module 300 calculates indoor environment according to the indoor environment temperature TA detected, and by above-mentioned formula (2)
Relative humidity calculation value HTA, and the indoor environment humidity TA to detecting and the indoor environment relative humidity calculation value of calculating
HTAJudged.If indoor environment temperature TA is more than 23 DEG C and indoor environment relative humidity calculation value HTALess than or equal to interior
Envionmental humidity HA simultaneously continues 3 minutes, then control module 300 controls magnetic valve 6 open-minded, now has refrigerant to flow through auxiliary capillary
Pipe 5, window-mounted air conditioner system enter anti-condensation operational mode.Meanwhile control module 300 starts to enter the service time of magnetic valve 6
Row timing, when the service time of magnetic valve 6 reaching 20 minutes, if indoor environment relative humidity calculation value HTAMore than or equal to inspection
The indoor environment relative humidity HA measured, control module 300 control magnetic valve 6 to close, and window-mounted air conditioner system exits anti-condensation fortune
Row mode, and start refrigerating operaton.
Further, as shown in figure 3, the control process of window-mounted air conditioner system comprises the following steps：
S101, start.
S102, compression mechanism cold operation 5 minutes.
Whether S103, the indoor environment temperature TA for judging to detect are more than 23 DEG C.If it is, perform step S104；If
It is no, return to step S102.
S104, judge indoor environment relative humidity calculation value HTAWhether indoor environment relative humidity HA is less than or equal to, and
Continue 3 minutes.If it is, step S105 is performed, if not, return to step S102.
S105, magnetic valve open timing 20 minutes.
S106, judge indoor environment relative humidity calculation value HTAWhether indoor environment relative humidity HA is more than or equal to.If
It is step S107 to be performed, if it is, return to step S105.
S107, closed electromagnetic valve, return to step S102.
Window-mounted air conditioner system according to embodiments of the present invention, indoor environment temperature is detected by temperature detecting module, and led to
Humidity detecting module detection indoor environment relative humidity is crossed, control module is when window-mounted air conditioner cooling system is run according to indoor ring
Border temperature computation indoor environment relative humidity calculation value, and according to indoor environment temperature and indoor environment relative humidity calculation value,
Control window-mounted air conditioner system enters anti-condensation operational mode, that is, controls magnetic valve to open so that capillary turns on.Therefore, it is of the invention
The window-mounted air conditioner system of embodiment can be on the premise of refrigeration be ensured, by controlling magnetic valve to open so that refrigerant flows through
Assisted capillary, so as to improve the refrigerant circulation of system, and then the evaporating temperature of evaporator is improved, effectively reduce condensation water
Produce, improve the comfortableness of user.

If on the basis of water capacity 17.7g/kg in air, indoor environment phase can be calculated according to above-mentioned formula (2)
To humidity calculated value.Now, the first preset temperature can be 23 DEG C, and corresponding relative air humidity is close to 100%.When indoor ring
Border temperature TA is more than such as 23 DEG C of the first preset temperature and indoor environment relative humidity calculation value HTAIt is relative less than or equal to indoor environment
Humidity HA and when continuing the first preset time such as 3 minutes, control magnetic valve is open-minded, window-mounted air conditioner system is entered anti-condensation operation
Pattern.
It should be noted that in order to ensure that window-mounted air conditioner system is in metastable running status, environment temperature indoors
Spend TA and indoor environment relative humidity calculation value HTAMeet it is default under the conditions of, also need to keep the first preset time such as 3 minutes.
In one embodiment of the invention, when magnetic valve is opened, the service time progress timing to magnetic valve, and
The service time of magnetic valve reaches the 3rd preset time and indoor environment relative humidity calculation value is more than or equal to the interior detected
Envionmental humidity, closed electromagnetic valve is controlled, window-mounted air conditioner system is exited anti-condensation operational mode.Wherein, the 3rd it is default when
Between can be 20 minutes.
According to the specific example of the present invention, on the basis of water capacity 17.7g/kg in air, when window-mounted air conditioner system
When starting refrigerating operaton, the run time of start recording compressor, when the run time of compressor reaches the second preset time such as 5
During minute, indoor environment temperature TA is detected, while detects indoor environment relative humidity HA, according to the indoor environment temperature detected
TA, and indoor environment relative humidity calculation value H is calculated by above-mentioned formula (2)TA, and the indoor environment humidity TA to detecting with
And the indoor environment relative humidity calculation value H calculatedTAJudged.If indoor environment temperature TA is more than 23 DEG C and indoor environment
Relative humidity calculation value HTALess than or equal to indoor environment relative humidity HA and continue 3 minutes, then control magnetic valve open-minded, now have
Refrigerant flows through assisted capillary, window-mounted air conditioner system is entered anti-condensation operational mode, starts simultaneously to magnetic valve when opening
Between carry out timing, when the service time of magnetic valve reaching 20 minutes, if indoor environment relative humidity calculation value HTAMore than etc.
In the indoor environment relative humidity HA detected, closed electromagnetic valve is controlled, window-mounted air conditioner system exits anti-condensation operational mode, and
Start refrigerating operaton.Further, the control process of window-mounted air conditioner system is as shown in Figure 3.
The control method of window-mounted air conditioner system according to embodiments of the present invention, when window-mounted air conditioner cooling system is run, root
Indoor environment relative humidity calculation value is calculated according to the indoor environment temperature detected, and according to indoor environment temperature and indoor environment
Relative humidity calculation value, control window-mounted air conditioner system enter anti-condensation operational mode, that is, control magnetic valve to open so that capillary
Conducting.Therefore, the control method of the window-mounted air conditioner system of the embodiment of the present invention can pass through on the premise of refrigeration is ensured
Control magnetic valve is opened so that refrigerant flows through assisted capillary, so as to improve the refrigerant circulation of system, and then raising evaporator
Evaporating temperature, effectively reduce the generation of condensation water, improve the comfortableness of user.
