Referring to fig. 1 and 2, an air conditioner 100 according to an embodiment of the present invention includes a temperature adjusting device 10, an air cleaning device 20, a memory 30, and a processor 40. The memory 30 stores at least one program, and the processor 40 is configured to execute the at least one program. As an example, the control method of the air conditioner 100 according to the embodiment of the present invention may be implemented by the air conditioner 100 according to the embodiment of the present invention, and may be applied to the air conditioner 100.
Here, the steps S12 and S14 of the control method of the air conditioner 100 according to the embodiment of the present invention may be implemented by the processor 40. That is, the processor 40 is configured to execute a program to determine whether a difference between the air dew point temperature at the air outlet 22 and the indoor air temperature is greater than a first threshold and control the temperature adjustment device 10 to stop cooling when the difference between the air dew point temperature at the air outlet 22 and the indoor air temperature is greater than the first threshold, and control the temperature adjustment device 10 to start the ventilation mode to sufficiently mix the air at the air outlet 22 and the indoor air when the temperature adjustment device 10 cools and the air purification device 20 operates.
The memory 30 may be a separate memory or a dedicated or dynamically allocated portion of the memory of the air conditioner 100. Processor 40 may be a stand-alone processor or a dedicated or dynamically assigned portion of the processor of air conditioner 100.
Along with the improvement of living standard of people, the air conditioner has been widely used in people's life, and the air circulation mode of air conditioner all is the inner loop at present, and the confined space can produce more dust, peculiar smell or harmful gaseous pollutants for a long time, can cause certain injury to people's health, can appear health problems such as flu, air conditioner disease for a long time. The household air conditioner of the fresh air system can create a comfortable environment for users, and meanwhile, the indoor air quality is improved. However, generally, the mode of exchanging fresh air for the air conditioner is basically that whether the temperature of outdoor air reaches the condition of starting the fresh air system is detected, and if the temperature of outdoor air reaches the condition of starting the fresh air system, the fresh air system is started; some schemes control the volume of supplying with indoor new trend through other detection conditions, and this kind of mode can control the fresh air volume that the new trend system supplyed, avoids indoor temperature variation too big, guarantees the refrigeration in room, heats the travelling comfort, but has often neglected the in service behavior of air conditioner, and new trend system and air conditioner do not use in a linkage, and the effect is not good.
The air conditioner 100 according to the embodiment of the present invention includes a temperature control device 10 and an air cleaning device 20, and the temperature control device 10 and the air cleaning device 20 are integrally provided. For example, for a cabinet, the temperature adjustment device 10 may be located above the air purification device 20. Of course, the air conditioner 100 may also be an on-hook, and is not limited herein. The thermostat 10 is used for cooling or heating. When the temperature adjusting device 10 performs refrigeration, low-pressure vapor of the refrigerant is sucked by a compressor (not shown in the figure), compressed into high-pressure vapor and discharged to an outdoor heat exchanger (not shown in the figure), the outdoor heat exchanger is a condenser, and outdoor air sucked by an axial flow fan (not shown in the figure) of an outdoor fan flows through the outdoor heat exchanger to take away heat emitted by the refrigerant, so that the high-pressure refrigerant vapor is condensed into high-pressure liquid. The high pressure liquid passes through a filter (not shown) and a throttle mechanism (not shown) and then is sprayed into the indoor heat exchanger 12, and the indoor heat exchanger 12 is an evaporator and is evaporated at a corresponding low pressure to absorb ambient heat. Meanwhile, the indoor fan sends the air which is cooled after releasing heat to the indoor through the air channel. Thus, the indoor air continuously circulates and flows to achieve the purpose of reducing the temperature or dehumidifying. The heating process of the thermostat 10 is the reverse of the cooling process. The ventilation mode of the thermostat 10 is with the indoor fan on and the outdoor compressor off. The indoor fan circularly blows air indoors to enable indoor air to flow.
Referring to fig. 1 again, the air purification device 20 may be a fresh air device, and the air purification device 20 includes an air outlet 22, an air inlet 24, an air purification module 26, and a blower 28. The air purification module 26 includes a plurality of filter screens arranged in a stack. The processor 40 controls the fan 28 to rotate at a certain wind speed so that the air inlet 24 introduces fresh outdoor air into the room, and the introduced air is filtered by a filter screen, wherein the filter screen may include an antibacterial and mildewproof primary filter screen, a sponge activated carbon layer, a honeycomb activated carbon layer and a high-efficiency filter screen. The processor 40 controls the fan 28 to send filtered air out through the outlet 22. Therefore, indoor air can be purified, and the health of a user is facilitated.
In some embodiments, a dehumidification module and/or a heating module is disposed between the intake 24 and the outtake 22. The dehumidification module may treat outdoor air introduced from the air inlet 24 to reduce the relative humidity of the air entering the room. The heating module may process outdoor air introduced from the intake 24 to increase the temperature of the air entering the room. The outdoor air is processed by the dehumidification module and/or the heating module and then sent out through the air outlet 22.
It can be understood that when the dew point temperature of the outdoor air is higher than the indoor air temperature, the air purification device 20 operates, and the air with higher outdoor temperature enters the air purification device 20 and meets the inner wall surface and the internal structure of the cold air duct 21 and the air outlet 22, so that condensation is easily generated. When the condensation is serious, the air purification device 20 may blow water. In one embodiment, when the dew point temperature of the outdoor air is much higher than the indoor air temperature, for example, the outdoor air temperature is 40 ℃ and the relative humidity is 60%, the corresponding dew point temperature is 30.93 ℃ at this time by looking up the table or the curve. If the indoor air temperature is 17 ℃ and is lower than the dew point temperature of the outdoor air, condensation can be generated by directly introducing a large amount of outdoor air. The dehumidification module is arranged between the air outlet 22 and the air inlet 24, after the outdoor air is subjected to dehumidification treatment, the relative humidity of the outdoor air can be reduced to 30%, the dew point temperature of the air at the air outlet is 19.17 ℃, the air at the air outlet 22 enters the room, the condensation risk is reduced, and the hidden danger still exists. In order to ensure the comfort in the room, the temperature adjustment device 10 may be controlled to turn off the cooling function, so as to keep the room temperature from continuously decreasing, and at the same time, the temperature adjustment device 10 may be controlled to turn on the ventilation mode, so as to sufficiently mix the air entering the room from the air outlet 22 with the room air, so as to raise the temperature of the room air. There is no risk of condensation or the risk of condensation is greatly reduced when the indoor air temperature is greater than the air dew point temperature at the outlet 22. At this time, the fan 28 of the air cleaning device 20 is operated at the calibrated lowest rotational speed. The first threshold may be set to be no greater than 2 deg.C (2 deg.C < 19.17 deg.C air dew point temperature at the outlet 22 deg.C-17 deg.C indoor air temperature). In other embodiments, the first threshold may be other values.
And when the difference between the air dew point temperature at the air outlet 22 and the indoor air temperature is smaller than or equal to the first threshold value, controlling the temperature adjusting device 10 to continue cooling. The fan 28 of the air cleaning device 20 may be operated at a preset rotational speed.
In summary, in the air conditioner 100 and the control method of the air conditioner 100 according to the embodiments of the present invention, the air purifying device 20 and the temperature adjusting device 10 are used in a linked manner, when the temperature adjusting device 10 cools and the air purifying device 20 operates, when the difference between the air dew point temperature at the air outlet 22 and the indoor air temperature is greater than the first threshold, the temperature adjusting device 10 stops cooling, and at this time, the ventilation mode of the temperature adjusting device 10 is turned on to sufficiently mix the air at the air outlet 22 with the indoor air, so as to increase the indoor air temperature. So, can reduce the risk of condensation and avoid indoor a large amount of condensation to can improve the comfort level of indoor environment.
Referring to fig. 4, in some embodiments, the dew point temperature of the air at the outlet 22 is obtained by:
s122: collecting the air temperature and air humidity at the air outlet 22; and
s124: and determining the air dew point temperature at the air outlet 22 corresponding to the air temperature and the air humidity at the air outlet 22 according to the relationship data of the pre-stored air temperature, the pre-stored air humidity and the pre-stored dew point temperature.
In some embodiments, the processor 40 is configured to execute at least one program to acquire the air temperature and the air humidity at the air outlet 22 and determine the air dew point temperature at the air outlet 22 corresponding to the air temperature and the air humidity at the air outlet 22 according to the pre-stored relationship data of the air temperature, the pre-stored air humidity, and the pre-stored dew point temperature.
Specifically, the air temperature at the air outlet 22 and the air humidity at the air outlet 22 may be detected by the first temperature sensor 23 and the first humidity sensor 25, respectively, and the processor 40 collects the air temperature at the air outlet 22 and the air humidity at the air outlet 22 by the first temperature sensor 23 and the first humidity sensor 25. The first temperature sensor 23 and the first humidity sensor 25 are installed at the outlet 22 to detect the air temperature and the air humidity at the outlet 22, respectively.
In some embodiments, the pre-stored relationship data for air temperature, pre-stored air humidity, and pre-stored dew point temperature comprises a curve or a look-up table.
In this way, the corresponding dew point temperature of the outdoor air is quickly obtained through a curve or a lookup table. The look-up table or curve may be stored in the air conditioner 100 or retrieved by the air conditioner 100 from the cloud.
Referring to fig. 5, in some embodiments, the control method further includes the steps of:
s22: when the temperature adjusting device 10 heats and the air purifying device 20 operates, it is determined whether a difference between a dew point temperature T3 of the indoor air and an air temperature T4 at the outlet 22 is greater than a second threshold Tb (T3-T4 > Tb; and
s24: when the difference between the dew-point temperature T3 of the indoor air and the air temperature T4 at the air outlet 22 is greater than the second threshold Tb (T3-T4 > Tb), the temperature adjustment device 10 is controlled to stop heating, and the temperature adjustment device 10 is controlled to start the ventilation mode to fully mix the air at the air outlet 22 with the indoor air.
In some embodiments, the processor 40 is configured to execute at least one program to determine whether a difference between a dew point temperature of the indoor air and an air temperature at the outlet 22 is greater than a second threshold when the temperature adjustment device 10 is heating and the air purification device 20 is operating, control the temperature adjustment device 10 to stop heating when the difference between the dew point temperature of the indoor air and the air temperature at the outlet 22 is greater than the second threshold, and control the temperature adjustment device 10 to start the ventilation mode to sufficiently mix the air at the outlet 22 with the indoor air.
It can be understood that the air purification device 20 and the temperature adjustment device 10 are used in a linkage manner, when the temperature adjustment device 10 heats and the air purification device 20 is working, and when the difference between the dew point temperature of the indoor air and the air temperature at the air outlet 22 is greater than the second threshold value, the temperature adjustment device 10 stops heating, and at this time, the ventilation mode of the temperature adjustment device 10 is started to sufficiently mix the air at the air outlet 22 with the indoor air, so that the temperature of the indoor air is reduced. So, can reduce the risk of condensation and avoid indoor a large amount of condensation to can improve the comfort level of indoor environment.
When the outdoor air temperature is lower than the dew point temperature of the indoor air, the air purification device 20 works, the air with lower outdoor temperature enters the air purification device 20, and the indoor hot air around the outer wall of the air duct 21 is easy to generate condensation on the outer wall surface of the air duct 21 of the cold air purification device 20. When the condensation is serious, the air purification device 20 may blow water. In one embodiment, when the indoor air temperature is 25 ℃ and the relative humidity is 50%, the corresponding dew point temperature at this time is 13.88 ℃ as can be obtained by looking up a table or a curve, and if the outdoor air at 0 ℃ is directly introduced at this time, there is a risk of condensation. The heating module is arranged between the air outlet 22 and the air inlet 24, the temperature of outdoor air can be raised to 10 ℃ after the outdoor air is heated, air at the air outlet 22 enters the room, condensation risk is reduced, and hidden danger still exists. In order to ensure the comfort of the room, the temperature adjustment device 10 may be controlled to turn off the heating function, so as to keep the room temperature from rising, and at the same time, the temperature adjustment device 10 may be controlled to turn on the ventilation mode, so as to sufficiently mix the air entering the room from the air outlet 22 with the room air, so as to lower the temperature of the room air. When the air temperature at the air outlet 22 is greater than the dew point temperature of the indoor air, there is no risk of condensation or the risk of condensation is greatly reduced. At this time, the fan 28 of the air cleaning device 20 is operated at the calibrated lowest rotational speed. The second threshold may be set to be no greater than 3.5 deg.c (3.5 deg.c < indoor air dew point temperature 13.88 deg.c-air temperature at the outlet 22 deg.c 10 deg.c). In other embodiments, the second threshold may be other values.
And when the difference between the dew point temperature of the indoor air and the air temperature at the air outlet 22 is smaller than or equal to the second threshold value, controlling the temperature adjusting device 10 to continue heating. The fan 28 of the air cleaning device 20 may be operated at a preset rotational speed.
Referring to fig. 6, in some embodiments, the dew point temperature of the indoor air is obtained by:
s222: collecting indoor air temperature and indoor air humidity; and
s224: and determining the dew point temperature of the indoor air corresponding to the indoor air temperature and the indoor air humidity according to the relationship data of the prestored air temperature, the prestored air humidity and the prestored dew point temperature.
In some embodiments, the processor 40 is configured to execute at least one program to acquire an indoor air temperature and an indoor air humidity and determine a dew point temperature of the indoor air corresponding to the indoor air temperature and the indoor air humidity according to relationship data of a pre-stored air temperature, a pre-stored air humidity, and a pre-stored dew point temperature.
Specifically, the indoor air temperature may be detected by the second temperature sensor 14 and the indoor air humidity may be detected by the second humidity sensor 16, and the processor 40 collects the indoor air temperature and the indoor air humidity through the second temperature sensor 14 and the second humidity sensor 16. The second temperature sensor 14 may be installed at an air inlet of an indoor fan of the temperature adjustment device 10, and the second humidity sensor 16 may also be installed at an air inlet of an indoor fan of the temperature adjustment device 10. So that the second temperature sensor 14 and the second humidity sensor 16 can accurately detect the indoor air temperature and the indoor air humidity, respectively. Of course, the second temperature sensor 14 and the second humidity sensor 16 may also be installed on the indoor heat exchanger 12 of the temperature adjusting device 10 to detect the indoor air temperature and the air humidity, respectively.
In some embodiments, the control method comprises the steps of: the fan 28 of the air cleaning device 20 is controlled to operate at the calibrated minimum rotational speed when the thermostat 10 opens the ventilation mode.
When the temperature adjustment device 10 stops cooling or heating and starts the ventilation mode, the fan 28 of the air purification device 20 operates at the calibrated lowest rotation speed, so that the air entering the room from the air outlet 22 is greatly reduced, the temperature of the air in the room is slowly changed, and condensation is not easy to occur. It is understood that the rotation speed of the fan 28 of the air purification apparatus 20 can be rotated within a certain range, and the rotation speed of the fan 28 of the air purification apparatus 20 can be controlled by controlling parameters such as the current or voltage of the fan 28 of the air purification apparatus 20.
It should be noted that the nominal rotation speed of the fan 28 for controlling the air cleaning device 20 refers to the rotation speed range for controlling the normal and safe operation of the fan 28 of the air cleaning device 20. For example, the rotation range of the fan 28 of the air purification device 20 is 800-. At this time, the calibrated minimum rotation speed of the fan 28 of the air purification device 20 is 800 r/min.
