Referring to fig. 1 and 2, an air conditioner 10 according to an embodiment of the present invention includes an air purifying device 12, a memory 13, and a processor 14. The air cleaning device 12 is formed with a first intake port 121, a second intake port 122, and an outlet port 123. A first air duct 124 is formed between the first air inlet 121 and the air outlet 123. A second air duct 125 is formed between the second air inlet 122 and the air outlet 123. The first air duct 124 is in selective communication with the second air duct 125. The first air inlet 121 is used for sucking indoor air, and discharging the air from the air outlet 123 to the indoor space after passing through the first air duct 124. The second air inlet 122 is used for sucking outdoor air, and discharging the outdoor air from the air outlet 123 to the indoor space after passing through the second air duct 125. The memory 13 stores at least one program.
Referring to fig. 3, a control method of the air conditioner 10 according to the embodiment of the present invention is applied to the air conditioner 10. The control method comprises the following steps:
s1, when the air purification apparatus 12 is operating and the first air duct 124 and the second air duct 125 are both open and connected, determining whether a temperature difference between a mixed air temperature of the first air duct 124 and the second air duct 125 and an indoor ambient temperature is greater than a first threshold; and
s2, when the temperature difference between the mixed air temperature and the indoor ambient temperature is greater than the first threshold value, the air purification device 12 is controlled to increase the amount of air passing through the first air duct 124 and/or decrease the amount of air passing through the second air duct 125.
The control method according to the embodiment of the present invention may be implemented by the air conditioner 10, for example, the processor 14 may be configured to execute at least one program to implement step S1 to determine whether a temperature difference between a temperature of the mixed air in the first air duct 124 and the temperature of the mixed air in the second air duct 125 and an indoor environment is greater than a first threshold value when the air purification apparatus 12 is running and the first air duct 124 and the second air duct 125 are both open and connected. The processor 1414 may be configured to execute at least one program to implement step S2 to control the air cleaning device 12 to increase the amount of air passing through the first air duct 124 and/or decrease the amount of air passing through the second air duct 125 when the temperature difference between the mixed air temperature and the indoor ambient temperature is greater than a first threshold.
Wherein the memory 13 may be a separate memory 13 or a dedicated or dynamically allocated portion of the memory 13 of the air conditioner 10. The processor 14 may be a stand-alone processor 14 or a dedicated or dynamically assigned portion of the processor 14 of the air conditioner 10.
Referring to fig. 1 again, in the embodiment of the present invention, the air conditioner 10 includes a temperature adjusting device 11, and the temperature adjusting device 11 and the air cleaning device 12 may be integrally provided. For example, for a cabinet, the temperature adjustment device 11 may be located above the air purification device 12. Of course, the air conditioner 10 may also be an on-hook, and is not limited thereto. The air conditioner 10 adjusts the indoor ambient temperature by the thermostat 11 to create a comfortable environment for the user. The thermostat 11 may operate in a cooling mode or a heating mode when activated. When the thermostat 11 operates in the cooling mode, heat is absorbed from the indoor environment and released to the outside, so that the indoor environment temperature is lowered. When the thermostat 11 operates the heating mode, heat is absorbed from the outdoor environment and released to the indoor, so that the indoor environment temperature rises.
When the temperature adjusting device 11 is operated, the indoor space is relatively closed, so that heat transfer is not easy to occur in the indoor environment and the outdoor environment. When the air conditioner 10 is used in a relatively closed indoor space for a long time, more dust, peculiar smell or harmful polluted gas is generated, certain harm is caused to the health of people, and health problems such as cold, air-conditioning diseases and the like can occur for a long time. The air cleaning device 12 may introduce fresh outdoor air to improve indoor air quality. However, the temperature difference between the indoor ambient temperature and the outdoor ambient temperature may cause condensation to be easily generated at the air outlet 123 after the outdoor air is introduced, and meanwhile, the temperature difference may reduce the comfort level of cooling and heating, which may affect the user experience.
The control method and the air conditioner 10 of the embodiment of the invention control the air purification device 12 to suck the outdoor air into the room to improve the indoor air quality, and the outdoor air and the indoor air are sucked into the air purification device 12 to be mixed by controlling the air purification device 12, so that the temperature difference between the mixed air temperature and the indoor environment temperature is smaller, and the condensation caused by the larger temperature difference when the mixed air enters the room can be prevented or reduced. When the temperature difference between the mixed air temperature and the indoor environment temperature is greater than the first threshold, the air purifying device 12 is controlled to pass through the air volume of the first air duct 124 and/or the air volume of the second air duct 125, so that the mixed air temperature changes less than the indoor environment temperature, the temperature difference between the mixed air temperature and the indoor environment temperature is reduced, the influence of the mixed air on the indoor environment temperature after entering the room is reduced, and the comfort level of the indoor environment is kept.
It is understood that when the temperature difference between the mixed air temperature and the indoor ambient temperature is greater than the first threshold value, the air purification device 12 may be controlled to increase the amount of air passing through the first air duct 124 and decrease the amount of air passing through the second air duct 125; or
Controlling the air cleaning device 12 to increase only the amount of air passing through the first air duct 124; or
The air cleaning device 12 is controlled to reduce only the amount of air passing through the second air duct 125.
In some embodiments, a mixed temperature sensor 15 is disposed in the air outlet 123 of the air purification apparatus 12, and the processor 14 collects the mixed air temperature through the mixed temperature sensor 15. In this way, the mixed temperature sensor 15 may detect the magnitude of the mixed air temperature in real time, so that the processor 14 controls the air purification device 12 to adjust the amount of air passing through the first air duct 124 and/or the amount of air passing through the second air duct 125 according to the mixed air temperature and the indoor ambient temperature.
Specifically, the first threshold may be flexibly configured according to actual needs. In one example, the first threshold may be 3 ℃. As such, when the temperature difference between the temperature of the mixed air and the temperature of the indoor environment is greater than the first threshold, the comfort level of the indoor environment may be affected when the mixed air enters the room. At this time, the processor 14 may control the air purifying device 12 to increase the amount of air passing through the first air duct 124, and the proportion of the indoor air in the mixed air is increased, so that the temperature difference between the temperature of the mixed air and the temperature of the indoor environment is reduced. Similarly, the processor 14 may control the air purifying device 12 to decrease the amount of air passing through the second air duct 125, so that the proportion of the outdoor air in the mixed air decreases, and the temperature difference between the temperature of the mixed air and the indoor ambient temperature decreases. Similarly, the processor 14 may control the air purifying device 12 to increase the amount of air passing through the first air duct 124, and control the air purifying device 12 to decrease the amount of air passing through the second air duct 125, so that the ratio of indoor air to outdoor air in the mixed air is increased and the ratio of outdoor air to indoor air is decreased, and thus the temperature difference between the mixed air temperature and the indoor ambient temperature is decreased.
In certain embodiments, the air purification device 12 includes a fresh air blower 126. It is understood that the fresh air blower 126 is operated to draw indoor air into the air cleaning device 12 through the first air inlet 121 and discharge the indoor air from the air outlet 123 to the room through the first air duct 124. The fresh air blower 126 can also suck the outdoor air into the air purification apparatus 12 through the second air inlet 122 and discharge the outdoor air from the air outlet 123 to the indoor through the second air duct 125.
In some embodiments, the air purification apparatus 12 may open the first air chute 124 or the second air chute 125 separately. For example, the first air duct 124 is provided with a first valve 1242. The second duct 125 is provided with a second valve 1252. The processor 14 may control the first valve 1242 to open or close to control the first air duct 124 to open or close, and the processor 14 may control the second valve 1252 to open or close to control the second air duct 125 to open or close.
In one example, the air purification apparatus 12 may open the first air duct 124 to filter indoor air and close the second air duct 125 to prevent outdoor air from entering the indoor space.
In some embodiments, the processor 14 may adjust the opening of the first valve 1242 to control the amount of air passing through the first air chute 124. Processor 14 may adjust the opening of second valve 1252 to control the amount of air passing through second air duct 125. It will be appreciated that controlling the opening of the first valve 1242 to increase at a given speed of the fresh air blower 126 facilitates increasing the amount of air passing through the first air chute 124. Controlling the opening of the second valve 1252 to decrease at a constant speed of the fresh air blower 126 facilitates reducing the amount of air passing through the first air duct 124.
In some embodiments, the air cleaning device 12 may be formed with two first air intakes 121 and two second air intakes 122. As such, the processor 14 may control the opening and closing amount of the first air inlet 121 and the second air inlet 122 respectively to control the amount of air passing through the first air duct 124 and the amount of air passing through the second air duct 125 respectively. Of course, the number of the first air inlets 121 and the second air inlets 122 can also be flexibly configured according to the requirement. Of course, a separate fan may be provided in the air duct, and the air volume of the air duct may be adjusted by the rotation speed of the fan.
Referring to fig. 4, in some embodiments, the control method includes the steps of:
s01, when the air purification apparatus 12 is in standby, determining whether the temperature difference between the indoor ambient temperature and the outdoor ambient temperature is less than or equal to a second threshold, the second threshold being greater than the first threshold; and
s02, when the temperature difference between the indoor ambient temperature and the outdoor ambient temperature is less than or equal to the second threshold, the air purification device 12 is controlled to operate and the first air duct 124 and the second air duct 125 are controlled to open and communicate.
In some embodiments, steps S01 and S02 may be implemented by the processor 14, that is, the processor 14 may be configured to execute at least one program to implement step S01 to determine whether the temperature difference between the indoor ambient temperature and the outdoor ambient temperature is less than or equal to the second threshold when the air purification apparatus 12 is in standby. The processor 14 may be configured to execute at least one program to implement step S02 to control the air purification apparatus 12 to operate and control both the first air duct 124 and the second air duct 125 to open and communicate when the temperature difference between the indoor ambient temperature and the outdoor ambient temperature is less than or equal to the second threshold value.
It can be understood that the higher gas of temperature meets the steam in the object after the object that the temperature is less than dew point temperature can condense on low temperature object surface to produce the condensation, air purification device 12 moves, and it is indoor to inhale outdoor air admission, and when the difference in temperature was great between indoor ambient temperature and the outdoor ambient temperature, produced the condensation at air outlet 123 easily, influenced user experience. In this way, when the temperature difference between the indoor ambient temperature and the outdoor ambient temperature is less than or equal to the second threshold, the processor 14 may control the air purification device 12 to operate and control the first air duct 124 and the second air duct 125 to open and communicate. It is understood that the second threshold may be set so that when the temperature difference between the indoor ambient temperature and the outdoor ambient temperature is smaller than or equal to the second threshold, it may be considered that condensation is not easily generated when the air purification device 12 operates.
It can be understood that the dew point temperature of the air is different under different temperature conditions, and the corresponding temperature difference value can be different. Specifically, the second threshold may be flexibly configured according to actual needs. Specifically, in one example, the second threshold may be 14 ℃.
In one example, the outdoor ambient temperature is 35 ℃, the indoor ambient temperature is 23 ℃, the temperature difference between the indoor ambient temperature and the outdoor ambient temperature is 12 ℃, and after the indoor air and the outdoor air are mixed, condensation is not easily generated when the mixed air enters the room. In another example, the outdoor ambient temperature is 10 ℃, the indoor ambient temperature is 23 ℃, the temperature difference between the indoor ambient temperature and the outdoor ambient temperature is 13 ℃, and after the indoor air and the outdoor air are mixed, condensation is not easily generated when the mixed air enters the room.
It is understood that the second threshold may be set to prevent or reduce condensation from being generated by the air cleaning device 12, the first threshold may be set to reduce the influence on the indoor ambient temperature after the outdoor air is introduced, and the second threshold is greater than the first threshold.
Referring to fig. 5, in some embodiments, step S01 includes:
s012, collecting indoor environment temperature and outdoor environment temperature; and
s014, calculating a temperature difference between the indoor ambient temperature and the outdoor ambient temperature and comparing it with a second threshold.
In some embodiments, steps S012 and S014 may be implemented by processor 14, that is, processor 14 may be configured to execute at least one program to implement step S012 to acquire indoor ambient temperature and outdoor ambient temperature. The processor 14 may obtain the indoor ambient temperature through an indoor temperature sensor 16 located in the indoor unit, and obtain the outdoor ambient temperature through an outdoor temperature sensor 17 located in the outdoor unit. The processor 14 may be configured to execute at least one program to implement step S014 to calculate a temperature difference between the indoor ambient temperature and the outdoor ambient temperature and compare the temperature difference with the second threshold.
In this way, the processor 14 may determine the temperature difference between the indoor ambient temperature and the outdoor ambient temperature to control whether the air purification device 12 is turned on or not, so as to prevent the air purification device 12 from introducing the outdoor air to generate condensation.
Referring again to fig. 4, in some embodiments, the control method includes the steps of:
and controlling the air purification device 12 to keep the standby state when the temperature difference between the indoor ambient temperature and the outdoor ambient temperature is greater than a second threshold value.
In some embodiments, the processor 14 may be configured to execute at least one program to control the air purification apparatus 12 to maintain the standby state when the temperature difference between the indoor ambient temperature and the outdoor ambient temperature is greater than the second threshold.
Thus, when the temperature difference between the indoor ambient temperature and the outdoor ambient temperature is greater than the second threshold, it can be considered that the condensation probability generated when the air purification device 12 operates is relatively high. Meanwhile, the introduction of outdoor air can greatly affect the indoor environment temperature, the comfort level of the indoor environment is reduced, and the user experience is affected. At this time, it is recommended that the air cleaning device 12 is not turned on, and the processor 14 controls the air cleaning device 12 to maintain a standby state. When the air purification device 12 is kept in the standby state, the fresh air blower 126 stops operating, and the first valve 1242 and the second valve 1252 are closed, which is beneficial to preventing impurities, dust and the like from entering the air purification device 12.
Wherein, the processor 14 may determine again after a period of time whether the temperature difference between the indoor ambient temperature and the outdoor ambient temperature is less than or equal to the second threshold. It will be appreciated that the air conditioner 10 may generally set a target temperature and the thermostat 11 operates to bring the indoor ambient temperature to the target temperature. When the indoor air does not reach the target temperature, the indoor ambient temperature may change due to the operation of the thermostat 11, and at this time, the air purifier 12 may generate condensation when the outdoor temperature is introduced due to the change in the indoor temperature. In this way, it is determined again after a certain period of time whether the temperature difference between the indoor ambient temperature and the outdoor ambient temperature is less than or equal to the second threshold value, so as to determine whether the air cleaning device continues to operate.
In some embodiments, the control method comprises the steps of:
and S3, controlling the air purification device 12 to keep operating in the current state when the temperature difference between the mixed air temperature and the indoor environment temperature is less than or equal to the first threshold value.
In some embodiments, step S3 may be implemented by processor 14, that is, processor 14 may be configured to execute at least one program to implement step S3 to control air purification device 12 to maintain the current state of operation when the temperature difference between the mixed air temperature and the indoor ambient temperature is less than or equal to the first threshold.
It can be understood that when the temperature difference between the mixed air temperature and the indoor environment temperature is smaller than or equal to the first threshold, the temperature difference between the mixed air temperature and the indoor environment temperature is smaller, and the comfort level of the indoor environment is not influenced or the influence is smaller when the mixed air enters the room. At this time, the air cleaning device 12 keeps operating in the current state, i.e., keeps operating the current blower, keeps the current opening degrees of the first valve 1242 and the second valve 1252, and/or keeps the current opening and closing amounts of the first air inlet 121 and the second air inlet 122. In this way, the amount of air passing through the first air duct 124 and the amount of air passing through the second air duct 125 in the air purification device 12 are stable, and when the indoor ambient temperature and the outdoor ambient temperature are not changed, and after the indoor air and the outdoor air are mixed, the temperature difference between the mixed air temperature and the indoor air temperature is kept smaller than or equal to the first threshold, which is beneficial to keeping the comfort level of the indoor environment.
In step S2, after controlling the air purifying device 12 to increase the amount of air passing through the first air duct 124 and/or decrease the amount of air passing through the second air duct 125, the difference between the temperature of the mixed air and the indoor ambient temperature decreases, and after a while, the processor 14 may determine again whether the temperature difference between the temperature of the mixed air in the first air duct 124 and the temperature of the mixed air in the second air duct 125 and the indoor ambient temperature is greater than the first threshold. If the temperature difference between the temperature of the mixed air of the first air duct 124 and the second air duct 125 and the indoor ambient temperature is still greater than the first threshold value, the air purification device 12 may be controlled again to increase the amount of air passing through the first air duct 124 and/or decrease the amount of air passing through the second air duct 125, so that the difference between the temperature of the mixed air and the indoor ambient temperature is further decreased. Until the temperature difference between the mixed air temperature and the indoor ambient temperature is less than or equal to the first threshold, the flow proceeds to step S3 to control the air cleaning device to operate in the current state.
Of course, in some embodiments, the processor 14 may determine again after a certain period of time whether the temperature difference between the temperature of the mixed air of the first air duct 124 and the second air duct 125 and the indoor ambient temperature is greater than the first threshold value. When the indoor air does not reach the target temperature, the indoor environment temperature may change due to the operation of the temperature adjustment device 11, and at this time, the temperature difference between the mixed air temperature and the indoor environment temperature may increase due to the change of the indoor environment temperature, thereby affecting the comfort level of the indoor environment. In this way, it is determined again at intervals whether the temperature difference between the temperature of the mixed air in the first air duct 124 and the temperature of the indoor environment in the second air duct 125 is greater than the first threshold, so that the air purification apparatus 12 can be controlled to increase the amount of air passing through the first air duct 124 and/or decrease the amount of air passing through the second air duct 125, thereby maintaining the comfort level of the indoor environment.
