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 2, an air conditioner 100 according to an embodiment of the present invention includes a temperature adjusting device 10 and an air cleaning device 20. The air cleaning device 20 is formed with an air duct 21, and the air duct 21 includes an air outlet 22 communicating with the indoor and an air inlet 24 communicating with the outdoor. The air cleaning device 20 includes a fan 28 located in the air duct 21, and the control method of the air conditioner 100 includes the steps of:
s12: when the air purification device 20 works, it is determined whether the absolute value Δ T of the difference between the air temperature at the air outlet 22 and the indoor air temperature is greater than or equal to a first threshold Ta1 and less than a second threshold Ta2(Ta1 ≦ Δ T < Ta 2;

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, 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 an absolute value Δ T of a difference between the air temperature at the air outlet 22 and the indoor air temperature is greater than or equal to a first threshold Ta1 and less than a second threshold Ta2(Ta1 ≦ Δ T < Ta 2?, and control the fan 28 to operate in the low wind range 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 absolute value Δ T is greater than or equal to a first threshold Ta1 and less than a second threshold Ta2(Ta1 ≦ Δ T < Ta 2).
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 fresh air system and the air conditioner are controlled and operated independently, and the fresh air system and the air conditioner are not used in a linkage manner, so that the effect is not good.
The air conditioner 100 according to the embodiment of the present invention includes the temperature adjusting device 10 and the air cleaning device 20, and the temperature adjusting device 10 and the air cleaning device 20 are integrally provided, that is, the temperature adjusting device 10 and the air cleaning device 20 are located in the same housing. For example, in the case of a cabinet air conditioner, the temperature adjustment device 10 may be located above the air purification device 20, and the temperature adjustment device 10 may also be located below 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 11 sends the air which is cooled after releasing heat to the indoor through the air duct. 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 such that the indoor fan 11 is operated and the outdoor compressor is stopped. The indoor fan 11 circulates air in the room to flow indoor air, thereby making the indoor air sufficiently mixed.
Referring again to fig. 1, the air purification device 20 may be a fresh air device for introducing outdoor air into the room to improve the indoor air quality. Specifically, the air purification device 20 includes an air outlet 22, an air inlet 24, an air purification module 26, and a fan 28. The air purification module 26 includes a plurality of filter screens arranged in a stack. The filter screen can include antibiotic mould proof primary filter screen, sponge activated carbon layer, honeycomb activated carbon layer and high-efficient filter screen. The processor 40 controls the fan 28 to rotate at a certain wind speed to establish an airflow, so that the fresh air from the outside enters the room after passing through the air inlet 24, the air purification module 26 and the air outlet 22 in sequence. 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 may be disposed between the intake vent 24 and the outtake vent 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 the air temperature and the air dew point temperature are in a positive correlation relationship, that is, the greater the air temperature is, the greater the air dew point temperature is, and when the air encounters an object lower than the air dew point temperature, the condensation phenomenon is easily generated. When the absolute value Δ T of the difference between the outdoor air temperature and the indoor air temperature is large, the air purification device 20 operates, and the outdoor air enters the air purification device 20 and is likely to generate condensation when encountering the inner wall surface of the air duct 21, the internal structure and the air outlet 22 having large temperature difference. When the condensation is serious, the air purification device 20 may blow water.
In one embodiment, when the temperature of the outdoor air is higher than the temperature of the indoor air, the temperature adjusting device 10 can perform cooling operation, and after the outdoor air enters the room from the outlet 22, the temperature of the air at the outlet 22 is also higher than the temperature of the indoor air. For example, when the air temperature at the air outlet 22 is 48 ℃ and the indoor air temperature is 20 ℃ (the absolute value Δ T of the difference between the two is 22 ℃), if a large amount of outdoor air is directly introduced into the room, condensation occurs; when the air temperature at the air outlet 22 is 43 ℃ and the indoor air temperature is 25 ℃ (the absolute value delta T of the difference between the air temperature and the indoor air temperature is 18 ℃), the condensation phenomenon is weakened after the rotating speed of the fan 28 is reduced to 650 r/min; when the air temperature at the air outlet 22 is 35 ℃ and the indoor air temperature is 25 ℃ (the absolute value delta T of the difference between the air temperature and the indoor air temperature is 10 ℃), condensation phenomenon cannot occur.
Therefore, in order to ensure the comfort in the room, the first threshold Ta1 may be set to 10 ℃, the second threshold Ta2 may be set to 19 ℃, and when there is a risk of condensation, the temperature adjustment device 10 may be controlled to turn off the cooling function, so as to keep the temperature in the room from decreasing, and at the same time, the temperature adjustment device 10 may be controlled to turn on the ventilation mode to fully mix the air entering the room from the air outlet 22 with the air in the room, and the fan 28 of the air purification device 20 may be controlled to operate at a low wind speed, so as to increase the temperature of the mixed air in the room by a small amplitude, so as to reduce the absolute value Δ T of the difference between the air temperature at the air outlet 22 and the air in the room, so as to prevent or greatly reduce the risk of condensation.
In another embodiment, when the temperature of the outdoor air is lower than the temperature of the indoor air, the temperature adjustment device 10 may turn on the heating mode, and after the outdoor air enters the room from the outlet 22, the temperature of the air at the outlet 22 is also lower than the temperature of the indoor air. For example, when the air temperature at the air outlet 22 is-7 ℃ and the indoor air temperature is 25 ℃ (the absolute value Δ T of the difference between the two is 32 ℃), if a large amount of outdoor air is directly introduced, the condensation phenomenon occurs; when the air temperature at the air outlet 22 is, for example, -3 ℃ and the indoor air temperature is, for example, 25 ℃ (the absolute value delta T of the difference between the two is 28 ℃), the rotating speed of the fan 28 is reduced to 650r/min, and the condensation phenomenon is weakened; the air temperature at the outlet 22 is, for example, 4 ℃, the indoor air temperature is, for example, 25 ℃ (the absolute value Δ T of the difference between the two is 21 ℃), and no condensation phenomenon occurs.
Therefore, in order to ensure the comfort in the room, the first threshold Ta1 may be set to 21 ℃, the second threshold Ta2 may be set to 28 ℃, and the temperature adjustment device 10 is controlled to turn off the heating function when there is a risk of condensation, so as to keep the temperature in the room from rising, and at the same time, the temperature adjustment device 10 is controlled to turn on the ventilation mode to fully mix the air entering the room from the air outlet 22 with the air in the room, and the fan 28 of the air purification device 20 is controlled to operate at a low wind speed, so as to reduce the temperature of the mixed air in the room by a small amplitude, so that the absolute value Δ T of the difference between the air temperature at the air outlet 22 and the air in the room is reduced, so as to prevent or greatly reduce the risk of condensation.
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 absolute value Δ T of the difference between the air temperature at the air outlet 22 and the indoor air temperature is greater than or equal to the first threshold Ta1 and less than the second threshold Ta2, the blower is controlled to operate at a low wind level, and at this time, the ventilation mode of the temperature adjusting device 10 is turned on to fully mix the air at the air outlet 22 and the indoor air, so that the absolute value Δ T of the difference between the air temperature at the air outlet and the indoor air temperature can be reduced. So, can reduce the risk of condensation in order to avoid indoor a large amount of condensation to can improve the comfort level of indoor environment when improving indoor air quality.
It will be appreciated that the fan 22 may be operated at variable speeds over a range of speeds, for example, as the current to the fan 22 increases, the speed of the fan 22 increases. In one example, fan 22 may be operated at a speed in a range of 600r/min to 1450 r/min. The rotating speed of the fan 22 can be divided into three stages, namely high, medium and low, the rotating speed range corresponding to the low wind stage is 600r/min-900r/min, the rotating speed range corresponding to the medium wind stage is 901r/min-1200r/min, and the rotating speed range corresponding to the high wind stage is 1201r/min-1450 r/min.
The first threshold Ta1 and the second threshold Ta2 may be specifically set in various cases. As in the above example, when the temperature of the outdoor air is higher than the indoor air temperature, the first threshold Ta1 is 10 ℃; when the temperature of the outdoor air is lower than the temperature of the indoor air, the first threshold Ta1 is 21 ℃.
Specifically, a first temperature sensor 23 may be provided at the outlet 22 to detect the air temperature at the outlet 22, and a second temperature sensor 14 may be provided at the outlet 13 of the temperature adjustment device 10 to detect the indoor air temperature. It is understood that when the thermostat 10 is operated for a certain period of time, the air temperature of the air outlet 13 is approximately the same as the room air temperature, and therefore, the temperature value detected by the second temperature sensor 14 located at the air outlet 13 can be taken as the room air temperature. Of course, the second temperature sensor 14 may be disposed at other positions in the room to detect the temperature of the indoor air, for example, the second temperature sensor 14 is disposed at the top of the air conditioner 100 and exposed to the room.
Therefore, in some embodiments, step S12 specifically includes:
collecting the air temperature at the outlet 22 and the indoor air temperature; and
the absolute value Δ T of the difference between the air temperature at the air outlet 22 and the room air temperature is calculated and compared with the first threshold Ta1 and the second threshold Ta 2.
In some embodiments, the processor 40 is configured to execute at least one program to perform the following steps:
collecting the air temperature at the outlet 22 and the indoor air temperature; and
the absolute value Δ T of the difference between the air temperature at the air outlet 22 and the room air temperature is calculated and compared with the first threshold Ta1 and the second threshold Ta 2.
The temperatures detected by the first temperature sensor 23 and the second temperature sensor 14 may be transmitted to the processor 40, so that the processor 40 may acquire the air temperature at the air outlet 22 and the room air temperature, and after calculation and comparison by the processor 40, the absolute value Δ T may be obtained to relate to the first threshold Ta1 and the second threshold Ta 2.
Referring to fig. 1, in some embodiments, a control method includes the steps of:
and S16, controlling the fan 22 to operate in a high wind gear when the absolute value delta T is smaller than the first threshold Ta 1.
In certain embodiments, the processor 40 is configured to execute at least one program to control the fan 22 to operate in a high wind regime when the absolute value Δ T is less than the first threshold Ta 1. For example, the fan 22 is operated at a speed of 1400 r/min.
Thus, when the absolute value Δ T is smaller than the first threshold Ta1, no condensation phenomenon occurs indoors, and at this time, the fan 22 is controlled to operate at a high wind level to accelerate the fresh air from outdoors to enter indoors, so as to improve the quality of the indoor environment. It should be noted that the thermostat 10 may operate in heating or cooling when the fan 22 is operating in a high wind range.
Referring to fig. 1 and 3, in some embodiments, the control method includes the steps of:
and S18, controlling the fan 22 to stop when the absolute value delta T is larger than or equal to the second threshold Ta 2.
In certain embodiments, the processor 40 is configured to execute at least one program to control the fan 22 to shut down when the absolute value Δ T is greater than or equal to the second threshold Ta 2. When the absolute value Δ T is equal to or greater than the second threshold value Ta2, if outdoor air is introduced, a condensation phenomenon occurs indoors. Therefore, by controlling the fan 22 to stop, the outdoor air can be prevented from entering the room, and the condensation phenomenon in the room can be prevented. It should be noted that the thermostat 10 can be operated for heating or cooling when the fan 22 is off.
It is understood that step S12 is continuous, or alternatively, it may be determined at intervals whether the absolute value Δ T of the difference between the air temperature at the outlet 22 and the indoor air temperature is greater than or equal to the first threshold Ta1 and less than the second threshold Ta2, and when the absolute value Δ T is greater than or equal to the first threshold Ta1 and less than the second threshold Ta2, the blower 22 is controlled to operate at a low wind level, and the temperature adjustment device 10 is controlled to start the ventilation mode so as to sufficiently mix the air at the outlet 22 and the indoor air; controlling the fan 22 to operate in a high gear when the absolute value Δ T is less than a first threshold Ta 1; when the absolute value Δ T is greater than or equal to the second threshold Ta2, the fan 22 is controlled to stop. This allows a more comfortable environment to be maintained indoors.
In certain embodiments, controlling the wind turbine 22 to operate in the low gear includes:
the fan 22 is controlled to operate at the calibrated minimum rotational speed.
In some embodiments, the processor 40 is configured to execute the at least one program to: the fan 22 is controlled to operate at the calibrated minimum rotational speed when the absolute value Δ T is greater than or equal to the first threshold Ta1 and less than the second threshold Ta 2.
Therefore, when the fan 22 operates at the calibrated lowest rotating speed, the air quantity entering the room is small, so that the temperature of the indoor air can be slowly changed, and condensation is prevented.
As with the above example, when the range of fan 22 speeds is 600r/min-1450r/min, then the calibrated minimum speed of fan 22 is 600r/min and fan 22 is operating at 600 r/min.
