Referring to fig. 1 and 2, the air conditioner 100 according to 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.
Among them, step S11, step S12, step S13, step S14 and step S15 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 detect whether the air purification apparatus 10 receives a fresh air change command while the air purification apparatus 10 is in a standby state; when the air purification device 10 receives a fresh air exchange instruction, the fresh air fan 12 is controlled to operate at a first rotating speed R1 so as to introduce outdoor fresh air into the room through the first air duct 16 and control the exhaust fan 14 to stand by, and meanwhile, the indoor air is detectedCO in air2Concentration value m1 and wind speed n1 at the first air outlet 162; after the fresh air fan 12 operates for a period of time at the first rotation speed R1, detecting the wind speed n2 at the first air outlet 162 and judging whether n2 is less than n 1; detecting CO in the indoor air when n2 < n12The concentration value of (a) M2 and whether M2 is not less than M1+ M1, wherein M1 represents CO2A first preset variation of the concentration value; and when M2 is more than or equal to M1+ M1, controlling the exhaust fan 14 to operate at a second rotating speed R2 to exhaust the indoor air to the outdoor through the second air duct 18.
Method for controlling air conditioner 100 and air conditioner 100 according to the embodiment of the present invention reduce CO at a reduced wind speed2When the concentration value M2 is more than or equal to M1+ M1, the exhaust fan 14 is controlled to operate at the second rotating speed R2 to exhaust the indoor air with the excessive carbon dioxide concentration to the outdoor so as to improve the quality of the indoor air, thereby improving the comfort level of the indoor environment.
In the embodiment of the present invention, after the air purification apparatus 10 receives the fresh air change command, the fresh air blower 12 operates at the first rotation speed R1 and the exhaust air blower 14 is in standby. The first rotation speed R1 can be in the range of 500-800R/min, for example 650R/min, and correspondingly the speed of introducing fresh outdoor air is 30m3H is used as the reference value. At this time, CO in the indoor air is detected2The concentration value m1 is 400ppm, the wind speed n1 at the first air outlet 162 is 6m/s, and the indoor air quality is good. The outdoor pressure and the indoor pressure may change with time, which may cause the wind speed at the first wind outlet 162 to change. Therefore, after the fresh air fan 12 is operated at the first speed R1 for a certain period of time (for example, 30 minutes), the wind speed n2 at the first wind outlet 162 is detected again. When n2 is greater than or equal to n1, the fresh air fan 12 still operates at the first rotating speed R1. When n2 < n1, the wind speed at first outlet 162 decreases, the amount of fresh outdoor air introduced decreases, and the quality of indoor air may deteriorate. At this time, CO in the indoor air is detected again2When the concentration value M2 is M2 is more than or equal to M1+ M1, which indicates that the carbon dioxide concentration in the indoor air is too high, the indoor air with the too high carbon dioxide concentration is discharged to the outdoor by controlling the exhaust fan 14 to operate at the second rotating speed R2 so as to improve the indoor air quality. When the exhaust fan 14 is operated at the second speed R2 to exhaust the indoor air, the fresh air fan 12 may be operated at the first speed R1 orThe air conditioner is operated at other rotating speeds to introduce outdoor fresh air, and is not limited in the process. M1 can be set at 800-1200ppm, preferably at 1000 ppm. The second rotation speed R2 may be in the range of 500-800R/min, for example 650R/min, corresponding to a discharge rate of 30m for indoor air3H is used as the reference value. Of course, the first rotation speed R1, the second rotation speed R2, and M1 can be flexibly set according to practical situations.
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 and 2, the air conditioner 100 further includes a temperature adjusting device 20. The temperature adjusting device 20 and the air cleaning device 10 may be integrally provided. For example, in the case of a cabinet, the temperature adjustment device 20 may be located above the air purification apparatus 10, and specifically, the temperature adjustment device 20 includes an indoor unit 22 and an outdoor unit, and the indoor unit 22 is located above the air purification apparatus 10. Of course, the air conditioner 100 may also be an on-hook, and is not limited herein. The temperature adjusting device 20 is used for cooling or heating. When the temperature adjusting device 20 performs cooling, low-pressure vapor of the refrigerant is sucked by a compressor (not shown), compressed into high-pressure vapor and discharged to an outdoor heat exchanger (not shown), the outdoor heat exchanger is a condenser, and outdoor air sucked by an axial flow fan (not shown) 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 throttling mechanism (not shown) and then is sprayed into an indoor heat exchanger (not shown), wherein the indoor heat exchanger 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 duct of the indoor unit 22. Thus, the indoor air continuously circulates and flows to achieve the purpose of reducing the temperature or dehumidifying. The heating process of the thermostat 20 is opposite to the cooling process.
In the present embodiment, the air purification device 10 is a fresh air device. The air purification device 10 includes a fresh air blower 12, a first air duct 16, a first air outlet 162, a first air inlet 164, and an air purification module 11. The air purification module 11 includes a plurality of filter screens arranged in a stack. The processor 40 controls the fresh air blower 12 to operate at a certain rotation speed so that the first air inlet 164 introduces outdoor fresh 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 fresh air fan 12 to send out the filtered air through the first air outlet 162. Further, the air purifying device 10 further includes an exhaust fan 14, a second air duct 18, a second air outlet 182, and a second air inlet 184. The processor 40 controls the exhaust fan 14 to operate at a rotational speed such that the indoor dirty air is discharged to the outside of the room through the second outlet 182. Thus, outdoor fresh air is introduced through the fresh air fan 12, and indoor dirty air is discharged through the exhaust fan 14, so that the indoor air is kept fresh, and the health of a user is facilitated.
It will be appreciated that the air path for the fresh air fan 12 and the air path for the exhaust air fan 14 may be different paths or share portions of the paths. When the air duct is shared, the shielding element can be utilized to switch the common part of the air duct so as to realize different functions. The positions of the first air outlet 162 and the second air inlet 184, and the positions of the first air inlet 164 and the second air outlet 182 can be flexibly set, and are not limited to the positional relationship shown in fig. 1.
Generally, to prevent outdoor contaminants from entering the room through the second duct 18, a baffle is installed at the second outlet 182 to block the second outlet 182 when the exhaust fan 14 is in standby. Therefore, in step S15, the flap can be controlled to move away to open the second outlet 182.
Referring to fig. 3, in some embodiments, the control method includes the following steps:
s16: when M2 < M1+ M1, it is judged whether M2 > M1+ M2, wherein M2 represents CO2A second preset variation of the concentration value, M2 < M1; and
s17: and when M2 is greater than M1+ M2, controlling the fresh air fan 12 to operate at a third rotating speed R3 and controlling the exhaust air fan 14 to stand by, wherein the third rotating speed R3 is greater than the first rotating speed R1.
In some embodiments, the processor 40 is configured to execute at least one program to determine whether M2 > M1+ M2 when M2 < M1+ M1 and control the fresh air fan 12 to operate at a third rotation speed R3 and control the exhaust air fan 14 to stand by when M2 > M1+ M2, wherein the third rotation speed R3 is greater than the first rotation speed R1. M2 represents CO2A second preset variation of the concentration value, M2 < M1. The third speed R3 is greater than the first speed R1.
It can be appreciated that as the wind speed at the first outlet 162 decreases and the CO CO2When the concentration value meets the condition that M1+ M2 is more than M2 is more than M1+ M1, the concentration of carbon dioxide in the indoor air is higher; in consideration of the energy saving requirement, the standby state of the exhaust fan 14 can be controlled, and the indoor air can be purified by increasing the outdoor fresh air quantity introduced into the room by increasing the rotating speed of the fresh air fan 12. M2 can be set at 300-700ppm, preferably 500 ppm. The third rotation speed R3 can be 1100-1300R/min, such as 1200R/min, and correspondingly, the speed of introducing the outdoor fresh air is 60m3H is used as the reference value. Of course, the third rotation speed R3, M2 can be flexibly set according to actual conditions.
Referring to fig. 3, in some embodiments, the control method includes the following steps:
s12: when M2 is not more than M1+ M2, the fresh air fan 12 is controlled to operate at a first rotating speed R1 and the exhaust air fan 14 is controlled to be in standby.
In some embodiments, the processor 40 is configured to execute at least one program to control the fresh air fan 12 to operate at the first speed R1 and the exhaust air fan 14 to be in standby mode when M2 is equal to or less than M1+ M2.
It can be appreciated that as the wind speed at the first outlet 162 decreases and the CO CO2When the concentration value meets the condition that M2 is not less than M1+ M2, the concentration of carbon dioxide in the indoor air is low, the quality of the indoor air is within the receiving range of a user, and at the moment, the fresh air fan 12 can be kept running at the first rotating speed R1 and the exhaust air fan 14 can be kept in standby. Thus, the energy consumption of the air purification device 10 is reduced while the indoor air quality is ensured.
In some embodiments, the air conditioner 100 includes an indoor unit 22 and a carbon dioxide concentration sensor 50, the carbon dioxide concentration sensor 50 is disposed in the indoor unit 22, and the carbon dioxide concentration sensor 50 is used for detecting CO2The concentration value of (c).
