Referring to fig. 1 and 2 together, an air conditioner 10 according to an embodiment of the present invention includes a temperature adjustment device 11, an air purification 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 an air conditioner according to an embodiment of the present invention is applied to an air conditioner 10. The control method comprises the following steps:
s1, when the temperature adjustment device 11 is in standby, the air purification device 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 less than or equal to a first threshold; and
s2, the temperature adjustment device 11 is controlled to operate when the temperature difference between the mixed air temperature and the indoor ambient temperature is less than or equal to the first threshold value.
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 air mixture in the first air duct 124 and the second air duct 125 and an indoor ambient temperature is less than or equal to a first threshold value when the temperature adjustment device 11 is in a standby state, the air purification device 12 is in an operating state, and the first air duct 124 and the second air duct 125 are both open and connected. The processor 14 may be configured to execute at least one program to implement step S2 to control the operation of the thermostat 11 when the temperature difference between the mixed air temperature and the indoor ambient temperature is less than or equal to the first threshold value.
Wherein the memory 13 may be a separate memory 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 or a dedicated or dynamically assigned portion of the processor 14 of the air conditioner 10.
In the embodiment of the present invention, the temperature adjusting device 11 and the air cleaning device 12 of the air conditioner 10 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 decrease the comfort 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 outdoor air into the room to improve the indoor air quality, and the temperature regulation device 11 sucks the outdoor air and the indoor air into the air purification device 12 to be mixed by controlling the air purification device 12 when in standby, so that the temperature difference between the mixed air temperature and the indoor environment temperature is small, and the condensation caused by the large temperature difference when the mixed air enters the room can be prevented. When the temperature difference between the mixed air temperature and the indoor environment temperature is smaller than or equal to the first threshold, the mixed air has small influence on the indoor environment temperature when entering the room, and the indoor environment comfort is favorably kept. In this case, the operation of the thermostat 11 is controlled, which is advantageous for reducing the operation load of the thermostat 11.
Referring again to fig. 1, in some embodiments, the air purification apparatus 12 includes a fresh air blower 126. The fresh air blower 126 can suck indoor air into the air purification apparatus 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.
Specifically, the first air inlet 121 and the second air inlet 122 may have the same size. In this way, when the temperature adjustment device 11 is in standby, and the air purification device 12 is operating and the first air duct 124 and the second air duct 125 are both open and connected, the amount of indoor air sucked into the air purification device 12 through the first air inlet 121 is the same as the amount of outdoor air sucked into the air purification device through the second air inlet 122. The mixed gas temperature is considered to be an average value of the indoor ambient temperature and the outdoor ambient temperature after equal amounts of the indoor air and the outdoor air are mixed. The outdoor environment temperature is not easy to change, at the moment, the temperature of the mixed gas changes along with the change of the indoor environment temperature, and the change range of the temperature of the mixed gas is half of the change range of the indoor environment temperature.
In one example, the indoor temperature is 25 ℃ and the outdoor temperature is 43 ℃, it is considered that the mixed gas temperature is 34 ℃ and the temperature difference between the mixed air temperature and the indoor ambient temperature is 9 ℃ after equal amounts of indoor air and outdoor air are mixed. At this time, the indoor ambient temperature is lowered by 1 ℃ due to the operation of the air cleaning device 12, and the temperature of the mixed air is lowered by 0.5 ℃. In another example, the indoor temperature is 25 ℃ and the outdoor temperature is 13 ℃, and it is considered that the mixed gas temperature is 19 ℃ and the temperature difference between the mixed air temperature and the indoor ambient temperature is 6 ℃ after equal amounts of indoor air and outdoor air are mixed. At this time, the indoor ambient temperature is lowered by 1 ℃ due to the operation of the air cleaning device 12, and the temperature of the mixed air is lowered by 0.5 ℃.
The first threshold value can be flexibly configured according to actual needs. In one example, the first threshold may be 3 ℃. So, mixed air temperature and indoor environment temperature differ less, and the mixed air gets into when indoor to the influence of room air less, is favorable to keeping the travelling comfort of indoor environment.
In some embodiments, processor 14 may control thermostat 11 to operate in either a cooling mode or a heating mode depending on the user selected mode of operation. In one example, if the user selects the cooling mode, the processor 14 controls the thermostat 11 to operate the cooling mode when the temperature difference between the mixed air temperature and the indoor temperature is less than or equal to the first threshold value. In another example, if the user selects the heating mode, the processor 14 controls the thermostat 11 to operate the heating mode when the temperature difference between the mixed air temperature and the indoor temperature is less than or equal to the first threshold.
Of course, in other embodiments, the processor 14 may control the thermostat 11 to operate the cooling mode or the heating mode according to the target temperature input by the user and the indoor ambient temperature. It will be appreciated that the air conditioner 10 may generally set a target temperature and control the thermostat 11 to operate to lower or raise the indoor ambient temperature to the target temperature. In one example, processor 14 controls thermostat 11 to operate the cooling mode to lower the indoor ambient temperature to the target temperature when the indoor ambient temperature is greater than the target temperature and the temperature difference between the mixed air temperature and the indoor temperature is less than or equal to the first threshold. In another example, processor 14 controls thermostat 11 to operate the heating mode to raise the indoor ambient temperature to the target temperature when the indoor ambient temperature is less than the target temperature and the temperature difference between the mixed air temperature and the indoor temperature is less than or equal to the first threshold.
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 this way, the air purification apparatus 12 can open the first air duct 124 to filter the indoor air and close the second air duct 125 to prevent the outdoor air from entering the indoor space.
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, wherein the first threshold is less than the second 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. 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 when the temperature difference between the indoor ambient temperature and the outdoor ambient temperature is less than or equal to the second threshold, it is considered that condensation is not easily generated when the air cleaning device 12 operates.
It can be understood that, when the temperatures are different, the dew point temperature of the air is different, 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 no greater than 19 ℃.
It will be appreciated that the second threshold is set to prevent condensation from occurring in the air cleaning device 12, and the first threshold is set to reduce the effect on the temperature of the indoor environment after the outdoor air is introduced, and typically the first threshold is less than the second 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 15 located in the indoor unit, and obtain the outdoor ambient temperature through an outdoor temperature sensor 16 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 indoor environment comfort 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 be in a standby state. When the air purification device 12 is in a 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 from entering the air purification device 12.
In some embodiments, the control method comprises the steps of:
s3, controlling the temperature adjustment device 11 to operate the ventilation mode when the temperature difference between the mixed air temperature and the indoor ambient temperature is greater than the first threshold value.
In certain 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 thermostat 11 to operate the ventilation mode when the temperature difference between the mixed air temperature and the indoor ambient temperature is greater than a first threshold.
It is understood that when the temperature difference between the temperature of the mixed air and the temperature of the indoor environment is greater than the first threshold value, the thermostat 11 directly operates in the cooling mode or the heating mode, and the comfort of the indoor environment may be affected by the simultaneous operation of the mixed air and the thermostat 11. In this manner, the processor 14 may control the thermostat 11 to operate the ventilation mode to accelerate the indoor air circulation, and the mixed air is mixed with the original indoor air to cause the indoor temperature to vary. In this way, the cooling mode or the heating mode is operated in a delayed manner, and the temperature adjusting device 11 is controlled to operate the cooling mode or the heating mode to keep the indoor environment comfortable when the temperature difference between the mixed air temperature and the indoor environment temperature is less than or equal to the first threshold value.
Specifically, when the thermostat 11 operates in the ventilation mode, the compressor (not shown) of the thermostat 11 stops operating, the refrigerant (not shown) stops flowing, and the heat exchanger 114 does not exchange heat with the ambient air. And the indoor fan 112 is operated. It is understood that the indoor fan 112 operates to circulate the indoor air so that the mixed air is mixed with the indoor air, thereby causing a change in the indoor temperature.
