Detailed Description
Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the accompanying drawings are exemplary only for the purpose of illustrating the embodiments of the present invention and are not to be construed as limiting the embodiments of the present invention.
Referring to fig. 1 to 3, an air conditioner 100 according to an embodiment of the present invention includes an air purifying device 10 and a temperature adjusting device 20, the air purifying device 10 includes an air duct 11 and a dehumidifying module 13 disposed in the air duct 11, the air duct 11 communicates with an indoor space and an outdoor space, and the control method includes:
s10, when the thermostat 20 is cooling and the air purification device 10 is in standby, determining whether the difference between the outdoor air dew point temperature T1 and the indoor air temperature T3 is greater than or equal to a first threshold Ta; and
and S20, controlling the fan 16 and the dehumidification module 13 of the air purification device 10 to work to dehumidify the outdoor air through the dehumidification module 13 and then enter the room when the difference between the outdoor air dew-point temperature T1 and the indoor air temperature T3 is greater than or equal to the first threshold Ta.
The air conditioner 100 of the embodiment of the present invention further includes 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, steps S10 to S20 of the control method of the air conditioner 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 outdoor air dew point temperature T1 and the indoor air temperature T3 is greater than or equal to a first threshold Ta when the temperature adjustment device 20 is cooling and the air purification device 10 is in standby; and when the difference between the outdoor air dew-point temperature T1 and the indoor air temperature T3 is greater than or equal to the first threshold Ta, controlling the fan 16 and the dehumidification module 13 of the air purification device 10 to work so as to dehumidify the outdoor air through the dehumidification module 13 and then enter the room.
According to the control method of the air conditioner 100 and the air conditioner 100, the fan 16 and the dehumidification module 13 of the air purification device 10 are controlled to work through the difference value between the dew point temperature of the outdoor air and the indoor air temperature T3, so that the outdoor air is dehumidified by the dehumidification module 13 to reduce the dew point temperature of the outdoor air and then discharged to the indoor space under the condition that the air conditioner 100 possibly generates condensation risk, condensation on the inner wall surface of the air outlet 19 of the air duct 11 of the air purification device 10 can be avoided, the use performance of the air conditioner 100 can be improved, the comfort level of the indoor environment can be improved, and the user experience is good.
In one example, after the dehumidification module 13 dehumidifies the outdoor air, the relative humidity of the outdoor air is reduced from 60% to 40%, so that the relative humidity of the air entering the room is 40%.
It should be noted that, when the temperature adjustment device 20 is cooling and the air purification device 10 is in standby, the outdoor air temperature T4 is higher than the indoor air temperature T3, outdoor air is introduced through the air purification device 10, and the outdoor air dew point temperature T1 is higher, so that when the outdoor air enters the air duct 11 passing through the air purification device 10 and is discharged to the indoor, condensation is likely to occur on the inner wall surface at the air outlet 19 of the air duct 11, in the present embodiment, the difference between the outdoor air dew point temperature T1 and the indoor air temperature T3 can indicate whether there is a risk that condensation may occur in the introduced outdoor air, and the introduced outdoor air is dehumidified to reduce the outdoor air dew point temperature T1 of the outdoor air in a case where there is a risk that condensation may occur.
It should be noted that, if the difference between the dew point temperature of the outdoor air and the indoor air temperature T3 reaches the first threshold Ta, and the first threshold Ta is a critical value when the outdoor air with higher temperature enters the air purification apparatus 10, the air on the inner wall of the air outlet 19 of the air duct 11 of the air purification apparatus 10 just condenses. That is, when the difference between the dew point temperature of the outdoor air and the indoor air temperature T3 is less than the first threshold Ta, the air conditioner 100 is free from or has a very low risk of condensation, and when the difference between the dew point temperature of the outdoor air and the indoor air temperature T3 is greater than or equal to the first threshold Ta, the air conditioner 100 is at risk of condensation.
Specifically, in one embodiment, the dehumidification module 13 may be a condensation dehumidification module. The dehumidification module 13 condenses outdoor air by means of condensation and cooling to realize dehumidification. When condensation dehumidification is not used, the dehumidification module 13 may not dehumidify the air. In another embodiment, the dehumidification module 13 may perform dehumidification by absorbing moisture in the air.
It is understood that the memory 30 may be a separate memory 30 or a dedicated or dynamically allocated portion of the memory 30 of the air conditioner 100. The processor 40 may be a stand-alone processor 40 or a dedicated or dynamically assigned portion of the processor 40 of the air conditioner 100.
Referring again to fig. 1, the temperature adjustment device 20 may be used for cooling or heating, and includes a compressor (not shown). When the temperature adjusting device 20 performs refrigeration, low-pressure vapor of the refrigerant is sucked by the compressor and compressed into high-pressure vapor, and then discharged to the outdoor heat exchanger (not shown), at this time, the outdoor heat exchanger is a condenser, and outdoor air sucked by the axial flow fan (not shown) of the outdoor fan 16 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 throttling mechanism (not shown) and then is sprayed into an indoor heat exchanger (not shown), the indoor heat exchanger is an evaporator at the moment and is evaporated at a corresponding low pressure to absorb surrounding heat, so that indoor air continuously circulates and flows, and the purposes of reducing temperature or dehumidifying are achieved. The heating process of the air conditioner 100 is opposite to the cooling process.
The air purification device 10 includes an air inlet 12, a filter screen 14, a fan 16, and an air outlet 19. The processor 40 controls the fan 16 to rotate at a certain rotation speed so that the air inlet 12 introduces fresh outdoor air into the room, and the introduced air is filtered by the filter screen 14, wherein the filter screen 14 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. Under the condition that the risk of condensation is possibly generated when the outdoor air is introduced, the dehumidifying module 13 is started to work, the outdoor air is dehumidified by the dehumidifying module 13 to reduce the dew point temperature of the outdoor air and then is discharged to the indoor, and the risk of condensation on the inner wall surface at the air outlet 19 of the air duct 11 of the air purifying device 10 is reduced. Or under the condition that the risk of condensation is not generated when the outdoor air is introduced, the dehumidification module 13 waits to work, and the processor 40 controls the fan 16 to directly send out the filtered air through the air outlet 19.
It should be noted that the air purification device 10 may be a fresh air device, and the fresh air device introduces outdoor air through the air inlet 12 and discharges the outdoor air to the indoor through the air outlet 19.
In the correlation technique, when temperature regulation apparatus 20 refrigerates, outdoor higher temperature's air gets into new fan unit, and the temperature of the internal wall face of the air outlet 19 department of the wind channel 11 of new fan unit is lower, leads to the outdoor higher temperature's of entering into new fan unit air emergence condensation like this easily, condenses into the drop of water to influence the performance of new fan unit, and user experience nature is not good. In the present embodiment, the difference between the outdoor air dew point temperature T1 and the indoor air temperature T3 can determine whether there is a risk of condensation of the introduced outdoor air, and the introduced outdoor air is dehumidified to lower the outdoor air dew point temperature T1 when there is a risk of condensation. So that the risk of condensation of the indoor air at the outlet 19 of the duct 11 can be reduced.
Preferably, the first threshold Ta is 9 degrees celsius. In one example, the outdoor air temperature T4 is 40 degrees celsius and the relative humidity is 60%, when the corresponding dew point temperature of the outdoor air is 30.93 degrees celsius by looking up a table or a curve. If the indoor air temperature T3 is 21 degrees celsius at this time, the difference between the outdoor air dew point temperature T1 and the indoor air temperature T3 is 30.93-21-9.93 degrees celsius, and since the difference (9.93 degrees celsius) is greater than the first threshold Ta (9 degrees celsius), that is, at this time, if the introduced outdoor air is not processed and is directly discharged indoors, there is a risk of condensation, at this time, the processor 40 controls the fan 16 and the dehumidifying module 13 of the air purifying device 10 to work so as to dehumidify the outdoor air through the dehumidifying module 13 and then enter indoors. For example, the relative humidity RH1 of the dehumidified outdoor air is reduced from 60% to 40%, the dew point temperature T1 of the outdoor air is 23.91, the difference between the dew point temperature T1 of the outdoor air and the indoor air temperature T3 is 23.91-21 ═ 2.91 ℃, and the difference is less than the first threshold Ta (9 ℃), and the treated outdoor air is discharged to the room without the risk of condensation.
Referring to fig. 2, in some embodiments, the control method includes the steps of:
and S30, controlling the fan 16 of the air purification device 10 to work and controlling the dehumidification module 13 to stand by when the difference between the outdoor air dew-point temperature T1 and the indoor air temperature T3 is smaller than a first threshold Ta.
Step S30 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 control the fan 16 of the air purification apparatus 10 to operate and control the dehumidification module 13 to be operated when the difference between the outdoor air dew-point temperature T1 and the indoor air temperature T3 is less than the first threshold Ta.
Since the fan 16 of the air cleaning device 10 is controlled to operate and the dehumidification module 13 is controlled to be operated when the difference between the outdoor air dew point temperature T1 and the indoor air temperature T3 is less than the first threshold value Ta in the present embodiment, in the case where it is determined that the air conditioner 100 does not risk condensation, the outdoor air can be directly introduced by the operation of the fan 16 while the dehumidification module 13 is maintained in the state of being operated, so that the cost can be saved.
In one example, the outdoor air temperature T4 is 40 degrees celsius and the relative humidity is 60%, when the corresponding dew point temperature of the outdoor air is 30.93 degrees celsius by looking up a table or a curve. If the indoor air temperature T3 is 25 degrees celsius at this time, the difference between the dew point temperature of the outdoor air and the indoor air temperature T3 is 30.93-25 degrees celsius to 5.93 degrees celsius, and since the difference (5.93 degrees celsius) is smaller than the first threshold Ta (9 degrees celsius), that is, at this time, the risk of condensation does not occur when the outdoor air is directly introduced, at this time, the processor 40 controls the fan 16 and the dehumidifying module 131 of the air purifying device 10 to operate, and the dehumidifying module 13 is ready to operate.
Referring to fig. 4, in some embodiments, the dew point temperature of the outdoor air in step S10 is obtained by:
s12, collecting the outdoor air temperature T4 and the outdoor air humidity RH 1; and
and S14, determining the outdoor air dew point temperature T1 corresponding to the outdoor air temperature T4 and the outdoor air humidity RH1 according to the pre-stored relation data of the air temperature, the pre-stored air humidity and the pre-stored dew point temperature.
Thus, the dew point temperature of the outdoor air can be rapidly acquired.
Specifically, referring again to fig. 3, the air conditioner 100 includes an outdoor temperature sensor 50 and an outdoor humidity sensor 60, wherein the outdoor temperature sensor 50 is used for detecting an outdoor air temperature T4, and the outdoor humidity sensor 60 is used for detecting an outdoor air humidity RH 1. The outdoor temperature sensor 50 and the outdoor humidity sensor 60 may be disposed at the intake vent 12 of the air cleaning device 10 or on the outdoor unit of the air conditioner.
It is understood that the pre-stored relationship data of the air temperature, the pre-stored air humidity and the pre-stored dew point temperature includes a curve or a lookup table, that is, the processor 40 may collect the outdoor air temperature T4 and the outdoor air humidity RH1 through the outdoor temperature sensor 50 and the outdoor humidity sensor 60, and may find the corresponding dew point temperature of the outdoor air through the curve or the lookup table.
Referring to fig. 5, in some embodiments, the air purifying apparatus 10 includes a heating module 15 disposed in the air duct 11, and the control method includes the steps of:
s40, when the air purification device 10 is in standby mode while the thermostat 20 is heating, determining whether the difference between the indoor air dew point temperature T2 and the outdoor air temperature T4 is greater than or equal to a second threshold Tb; and
and S50, controlling the fan 16 and the heating module 15 of the air purification device 10 to work when the difference between the indoor air dew point temperature T2 and the outdoor air temperature T4 is greater than or equal to a second threshold Tb so as to heat the outdoor air passing through the heating module 15 and enter the room.
Steps S40 to S50 of the control method of the air conditioner 100 of 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 the difference between the indoor air dew point temperature T2 and the outdoor air temperature T4 is greater than or equal to the second threshold Tb when the thermostat 20 is heating and the air purification apparatus 10 is in standby; and when the difference value between the indoor air dew point temperature T2 and the outdoor air temperature T4 is greater than or equal to a second threshold value Tb, controlling the fan 16 and the heating module 15 of the air purification device 10 to work so as to heat the outdoor air passing through the heating module 15 and then enter the room.
In the related art, when the temperature adjusting device 20 heats, and the air conditioner 100 starts the fresh air function, air at a lower outdoor temperature enters the fresh air device, the temperature of the outer wall of the air outlet 19 of the air duct 11 of the indoor fresh air device is higher, and the temperature of the inner wall surface of the air outlet 19 of the air duct 11 of the fresh air device is lower, so that when air at a lower outdoor temperature is introduced, the indoor air at the air outlet 19 of the air duct 11 of the indoor fresh air device is prone to be condensed, and the air is condensed into small water drops, so that the use performance of the fresh air device is affected, and the user experience is poor. In the present embodiment, the difference between the dew point temperature T1 of the outdoor air and the indoor air temperature T3 indicates whether there is a risk of condensation of the introduced outdoor air, and the introduced outdoor air is subjected to a heating process by the heating module 15 to raise the temperature of the outdoor air entering the air purification apparatus 10 when there is a risk of condensation. So that the risk of condensation of the indoor air at the outlet 19 of the duct 11 can be reduced.
It should be noted that, if the difference between the dew point temperature of the indoor air and the outdoor air temperature T4 is the second threshold Tb, and the second threshold Tb is a critical value at which the indoor air at the outer wall of the air outlet 19 of the air duct 11 of the fresh air blower device does not just condense when the air at the outdoor lower temperature enters the fresh air blower device. That is, when the difference between the dew point temperature of the indoor air and the outdoor air temperature T4 is less than the second threshold Tb, the air conditioner 100 does not suffer from or has a very low risk of condensation, and when the difference between the dew point temperature of the indoor air and the outdoor air temperature T4 is greater than or equal to the second threshold Tb, the air conditioner 100 suffers from condensation.
Preferably, the second threshold Tb is 12 degrees celsius. In one example, the room air temperature T3 is 25 degrees celsius and the relative humidity is 60%, and the corresponding dew point temperature of the room air is 16.72 degrees celsius when the corresponding dew point temperature is found by a look-up table or a curve. If the temperature T1 of the outdoor air is 4 degrees celsius at this time, the difference between the dew point temperature of the indoor air and the temperature T1 of the outdoor air is 16.72-4-12.72 degrees celsius, and since the difference (12.73 degrees celsius) is greater than the second threshold Tb (12 degrees celsius), that is, at this time, if the introduced outdoor air is not processed and directly discharged into the room, there is a risk of condensation, and at this time, the processor 40 controls the fan 16 and the heating module 15 of the air purification apparatus 10 to operate to heat the outdoor air through the heating module 15 and then enter the room.
It will be appreciated that the heating module 15 may be a resistive sheet that the processor 40 may control to generate heat to raise the temperature of the introduced outdoor air.
It should be noted that the heating module 15 and the dehumidifying module 13 may be the same component, and the processor 40 may control the dehumidifying module 13 to operate in a condensing manner to achieve the dehumidifying effect when the temperature adjusting device 20 is cooling, and may control the dehumidifying module 13 to operate in a heating manner to achieve the air heating effect when the temperature adjusting device is heating.
Referring again to fig. 5, in some embodiments, the control method includes the steps of:
and S60, controlling the fan 16 of the air purification device 10 to work and controlling the heating module 15 to stand by when the difference between the indoor air dew point temperature T2 and the outdoor air temperature T4 is less than a second threshold Tb.
Step S60 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 control the fan 16 of the air cleaning device 10 to operate and control the heating module 15 to be on standby when the difference between the indoor air dew point temperature T2 and the outdoor air temperature T4 is less than the second threshold value Tb.
Since the fan 16 of the air cleaning device 10 is controlled to operate and the heating module 15 is controlled to be operated when the difference between the indoor air dew point temperature T2 and the outdoor air temperature T4 is less than the second threshold value Tb in the present embodiment, the outdoor air can be directly introduced by the operation of the fan 16 while the heating module 15 is kept in a state to be operated when it is determined that the air conditioner 100 does not have a risk of condensation, and thus, the cost can be saved.
In one example, when the temperature control device 20 is heating and the air purification device 10 is in standby, the indoor air temperature T3 is 25 degrees celsius, the relative humidity is 60%, and the corresponding dew point temperature of the indoor air is 16.72 degrees celsius. If the outdoor air temperature T4 is 8 degrees celsius at this time, the difference between the dew point temperature of the indoor air and the outdoor air temperature T4 is 16.72-8 degrees celsius to 8.72 degrees celsius, and since the difference (8.72 degrees celsius) is smaller than the second threshold Tb (12 degrees celsius), the processor 40 controls the fan 16 of the air purification apparatus 10 to operate and controls the heating module 15 to be operated.
Referring to fig. 6, in some embodiments, the dew point temperature of the indoor air in step S40 is obtained by:
s42, collecting indoor air temperature T3 and indoor air humidity RH 2; and
and S44, determining the indoor air dew point temperature T2 corresponding to the indoor air temperature T3 and the indoor air humidity RH2 according to the relationship data of the prestored air temperature, the prestored air humidity and the prestored dew point temperature.
Thus, the dew point temperature of the indoor air can be rapidly acquired.
Specifically, referring again to fig. 3, the air conditioner 100 includes an indoor temperature sensor 70 and an indoor humidity sensor 80, wherein the indoor temperature sensor 70 is used for detecting an indoor air temperature T3, and the indoor humidity sensor 80 is used for detecting an indoor air humidity RH 2.
