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 a temperature adjusting device 20 and an air cleaning device 10. The control method of the air conditioner comprises the following steps:
s10, when the temperature adjusting device 20 is refrigerating and the air purifying device 10 is in standby, judging whether the difference value between the moisture content A of the outdoor air and the moisture content B of the indoor air is larger than or equal to a first preset threshold value C1(A-B is larger than or equal to C1; and
and S20, controlling the fan of the air purification device 10 to work at a first preset rotating speed V1 to introduce the outdoor air into the room when the difference value between the moisture content A of the outdoor air and the moisture content B of the indoor air is greater than or equal to a first preset threshold value C1.
Referring to fig. 2 to 3, an air conditioner 100 according to an embodiment of the present invention includes a temperature adjusting device 20, an air purifying device 10, 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 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 moisture content A of the outdoor air and the moisture content B of the indoor air is greater than or equal to a first preset threshold C1(A-B ≧ C1; and when the difference value between the moisture content A of the outdoor air and the moisture content B of the indoor air is greater than or equal to a first preset threshold value C1, controlling the fan of the air purification device 10 to work at a first preset rotating speed V1 so as to introduce the outdoor air into the indoor space.
The control method of the air conditioner and the air conditioner 100 in the above embodiment control the operation rotation speed of the fan of the air purification device 10 by the difference between the moisture content a of the outdoor air and the moisture content B of the indoor air, so that the fan of the air purification device 10 introduces the air with higher outdoor moisture content, thereby solving the problem of low moisture content of the indoor air, further maintaining a good humidity environment indoors, improving the comfort level of the indoor environment, and having low cost.
In the related art, it is general to take condensed water by cooling using a semiconductor element mounted on an air conditioner and introduce the condensed water into a room for humidification, but such a solution is costly and the efficiency of humidification is slow. In the embodiment of the invention, when the difference value between the moisture content A of the outdoor air and the moisture content B of the indoor air is greater than or equal to the first preset threshold value C1(A-B is greater than or equal to C1), the fan of the air purification device is controlled to work at the first preset rotating speed V1 so as to introduce the outdoor air into the indoor space. Therefore, air with high outdoor moisture content can be introduced, so that the moisture content B of indoor air can be improved, the cost is low, and the efficiency is high.
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 an axial flow fan (not shown) of the 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), 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 purifying device 10 may be a fresh air device, and the air purifying 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. The processor 40 controls the fan 16 to send out filtered air through the outlet 19. In this way, air having a high outdoor moisture content can be introduced, so that the moisture content B of the indoor air can be increased. Meanwhile, indoor air can be purified, and the health of a user is facilitated. In the embodiment of the present invention, the air duct in the air cleaning device 10 is substantially in a zigzag shape. When the air cleaning device 10 is in standby, it can be understood that the fan 16 of the air cleaning device 10 is stopped.
Referring to fig. 4, in certain embodiments, the moisture content a of the outdoor air is obtained by:
s12, collecting the outdoor air temperature T1 and the outdoor air relative humidity RH 1; and
and S14, determining the moisture content A of the outdoor air corresponding to the outdoor air temperature T1 and the outdoor air relative humidity RH1 according to the pre-stored relation data of the air temperature, the pre-stored air relative humidity and the air moisture content.
Referring to fig. 5, in some embodiments, the moisture content B of the indoor air is obtained by:
s16, collecting indoor air temperature T2 and indoor air relative humidity RH 2; and
and S18, determining the moisture content B of the indoor air corresponding to the indoor air temperature T2 and the indoor air relative humidity RH2 according to the pre-stored relation data of the air temperature, the pre-stored air relative humidity and the air moisture content.
Specifically, the air conditioner 100 includes an outdoor humidity sensor 50, an indoor humidity sensor 60, an outdoor temperature sensor 70, and an indoor temperature sensor 80. The outdoor humidity sensor 50 and the outdoor temperature sensor 70 may be disposed at the air inlet 12 of the outdoor unit or the air cleaning device 10. The outdoor humidity sensor 50 is used to detect the outdoor air relative humidity RH 1. The outdoor temperature sensor 70 is used to detect an outdoor air temperature T1. The indoor humidity sensor 60 and the indoor temperature sensor 80 may be provided at the outlet 19 of the indoor unit or the air cleaning device 10. The indoor humidity sensor 60 is used to detect the indoor air relative humidity RH 2. The indoor temperature sensor 80 is used to detect an indoor air temperature T2. The relationship data of the pre-stored air temperature, the pre-stored air relative humidity and the air moisture content can be obtained through a curve or a table look-up.
In the embodiment of the present invention, when the temperature adjustment device 20 is cooling, the outdoor temperature is generally higher than the indoor temperature, and it can be known from the following table one that the moisture content a of the outdoor air is higher than the moisture content B of the indoor air under the condition that the relative humidity of the outdoor air and the relative humidity of the indoor air are the same, that is, in the cooling state, when the difference between the moisture content a of the outdoor air and the moisture content B of the indoor air is greater than or equal to the first preset threshold value C1, the fan 16 of the air purification device 10 can be controlled to operate to introduce the air with higher outdoor moisture content to increase the moisture content B of the indoor air.
Table one: corresponding relation of temperature, relative humidity and moisture content
It is understood that moisture content refers to the amount of water vapor contained per kilogram of dry air and that relative humidity refers to the percentage of the amount of water vapor contained in the air at a certain temperature to the amount of saturated water vapor at that temperature.
Preferably, the first predetermined threshold is 4 g/kg. The first preset rotating speed V1 ranges from 1000r/min to 1300 r/min. When the temperature adjusting device 20 is used for cooling, the indoor temperature and humidity are relatively low, the outdoor temperature and humidity are relatively high, in one example, when the outdoor air temperature is 35 degrees and the relative humidity is 40%, the moisture content a of the outdoor air is 14.3g/kg, and when the indoor air temperature is 25 degrees and the relative humidity is 40%, the moisture content B of the indoor air is 8.47g/kg, and the difference between the moisture content a of the outdoor air and the moisture content B of the indoor air is 14.3-8.47 which is 5.83 g/kg. Since 5.83g/kg is greater than the first preset threshold (4g/kg), the processor 40 controls the fan 16 of the air cleaning device 10 to operate at the first preset rotation speed V1 to introduce the outdoor air into the room.
Referring to fig. 6, in some embodiments, the control method further includes the steps of:
s30, after the fan 16 of the air purification apparatus 10 operates at the first preset rotation speed V1 for a first preset time period, determining whether the difference between the moisture content a of the outdoor air and the moisture content B of the indoor air is greater than a second preset threshold C2 and less than a first preset threshold C1(C2 < a-B < C1; and
and S40, when the difference value between the moisture content A of the outdoor air and the moisture content B of the indoor air is greater than a second preset threshold value C2 and smaller than a first preset threshold value, controlling the fan 16 of the air purification device 10 to change from the first preset rotating speed V1 to the second preset rotating speed V2 to operate, wherein the second preset rotating speed V2 is smaller than the first preset rotating speed V1.
Steps S30 to S40 of the control method of the air conditioner of the embodiment of the present invention may be implemented by the air conditioner 100 of the embodiment of the present invention. That is, the processor 40 is configured to execute at least one program to determine whether the difference between the moisture content a of the outdoor air and the moisture content B of the indoor air is greater than the second preset threshold C2 and less than the first preset threshold C1(C2 < a-B < C1; and when the difference value between the moisture content A of the outdoor air and the moisture content B of the indoor air is greater than a second preset threshold value C2 and less than a first preset threshold value, controlling the fan 16 of the air purification device 10 to change from a first preset rotating speed V1 to a second preset rotating speed V2 for operation, wherein the second preset rotating speed V2 is less than the first preset rotating speed V1.
According to the embodiment of the invention, after the fan of the air purification device operates at the first preset rotating speed V1 for the first preset time, the operating rotating speed of the fan 16 of the air purification device 10 is controlled and adjusted according to the difference value between the moisture content A of the outdoor air and the moisture content B of the indoor air, so that the moisture content B of the indoor air can be kept in a reasonable range, and the comfort level of the environment can be improved. In one example, the first predetermined period of time is 30 minutes.
It can be understood that, during the operation of the fan 16 of the air cleaning device 10 at the first preset rotation speed V1, as the air with higher outdoor moisture content enters the room, the moisture content B of the indoor air gradually increases, and the difference between the moisture content a of the outdoor air and the moisture content B of the indoor air gradually decreases. At this time, in order to ensure that the moisture content in the room can be maintained within a suitable range, it is necessary to reduce the rotational speed of the fan 16 of the air cleaning device 10 to reduce the introduction of the air volume.
Preferably, the second predetermined threshold value C2 is 1.8 g/kg. The second preset rotating speed V2 is in the range of 800r/min-1000 r/min. As the fan 16 of the air cleaning device 10 continuously introduces the air having a high outdoor moisture content, the indoor moisture content increases. In one example, when the outdoor air temperature is 35 degrees and the relative humidity is 40%, the moisture content a of the outdoor air is 14.3g/kg, and when the indoor air temperature is 25 degrees and the relative humidity is 50%, the moisture content B of the indoor air is 10.62/kg, and the difference between the moisture content a of the outdoor air and the moisture content B of the indoor air is 14.3-10.62-3.68 g/kg. Since 3.68g/kg is greater than the second preset threshold C2(1.8g/kg) and less than the first preset threshold (4g/kg), the processor 40 controls the fan 16 of the air cleaning device 10 to operate at the second preset rotation speed V2 to introduce the outdoor air into the room.
Referring to fig. 7, in some embodiments, the control method further includes the steps of:
s50, after the fan 16 of the air purification apparatus 10 operates at the second preset speed V2 for a second preset time period, determining whether the difference between the moisture content a of the outdoor air and the moisture content B of the indoor air is less than or equal to a second preset threshold C2(a-B < C2; and
and S60, controlling the fan 16 of the air purification device 10 to stop working when the difference value between the moisture content A of the outdoor air and the moisture content B of the indoor air is less than or equal to a second preset threshold value C2.
Steps S50 to S60 of the control method of the air conditioner of the embodiment of the present invention may be implemented by the air conditioner 100 of the embodiment of the present invention. That is, the processor 40 is configured to execute at least one program to determine whether the difference between the moisture content a of the outdoor air and the moisture content B of the indoor air is less than or equal to the second preset threshold C2(a-B < C2; and controlling the fan 16 of the air purification device 10 to stop working when the difference value between the moisture content A of the outdoor air and the moisture content B of the indoor air is smaller than or equal to a second preset threshold value C2.
After the fan 16 of the air purification device 10 operates at the second preset rotation speed V2 for the second preset time, the operation state of the fan 16 of the air purification device 10 is controlled and adjusted according to the difference between the moisture content a of the outdoor air and the moisture content B of the indoor air, so that the moisture content B of the indoor air can be kept in a reasonable range, and the comfort level of the environment can be improved.
It can be understood that, during the operation of the fan 16 of the air cleaning device 10 at the second preset rotation speed V2, since the moisture content B of the indoor air gradually increases as the air with higher outdoor moisture content enters the indoor space, the difference between the moisture content a of the outdoor air and the moisture content B of the indoor air gradually decreases and is less than or equal to the second preset threshold C2. At this time, in order to ensure that the moisture content in the room can be maintained within a more appropriate range, it is necessary to control the fan 16 of the air cleaning device 10 to stop operating. In one example, the second predetermined period of time is 25 minutes.
In some embodiments, the control method further comprises:
when the thermostat 20 heats, the air cleaner 10 is controlled to stand by.
The control method of the air conditioner according to the embodiment of the present invention can be realized by the air conditioner 100 according to the embodiment of the present invention. That is, the processor 40 is configured to execute at least one program to control the air cleaning device 10 to stand by while the thermostat 20 is heating.
Specifically, generally, since the humidity content a of the outdoor air is lower than the humidity content B of the indoor air when the temperature adjusting device 20 heats, the air purifying device 10 is controlled to stand by to avoid the introduction of air having a low outdoor humidity content. When the air cleaning device 10 is in standby, the fan 16 stops operating.
