Detailed Description
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below.
Fig. 1 is a schematic structural diagram of an indoor unit of an air conditioner according to the present invention, which shows an appearance structure of the indoor unit of the air conditioner, and in addition to an air inlet usually located at the top of the indoor unit and an air outlet located at the lower portion of the indoor unit, a front panel grill is further disposed on the front surface of the casing of the indoor unit, and when the front panel grill is opened, the air inlet can be assisted, and the air flow rate of the indoor unit is increased without continuously increasing the rotation speed of the indoor fan.
The indoor unit is also provided with an air inlet temperature sensor (not shown in the figure), which is arranged inside the air inlet and used for detecting the air inlet temperature of the indoor unit, wherein the air inlet temperature can be used for representing the indoor environment temperature.
Fig. 2 is a schematic flowchart of a control method of an air conditioner, which may be applied to the air conditioner, in an embodiment of the present invention, the method including:
s201, if the air conditioner is started in a refrigeration mode, acquiring indoor environment temperature TiAnd a user-set temperature Td；
When the user starts the air conditioner, the user can select the air conditioner to start in a heating mode, a dehumidification mode, a ventilation mode or a cooling mode, and the user mainly starts in the cooling mode in the discussion of the application. If the user sets the operation mode of the air conditioner to the cooling mode within a period of time, for example, 1 minute after the air conditioner on command is issued, and the user should also consider that the air conditioner is turned on in the cooling mode, the indoor ambient temperature T at that timeiIt should also be regarded as the indoor temperature when the air conditioner is turned on in the cooling mode. Wherein the indoor ambient temperature TiCan be known by a temperature sensor arranged at the air inlet of the indoor unit of the air conditioner.
And the user sets the temperature TdWhen the user sends out the air conditioner starting command, the temperature stored in the remote controller is the current user set temperature TdIf the user sets the air-conditioning temperature within a period of time, for example, 1 minute, 2 minutes or 5 minutes after the air-conditioning turn-on instruction is issued, the air-conditioning temperature newly set by the user should also be taken as the user-set temperature Td. After the user resets the temperature within the above time, the indoor instant environmental temperature when the user resets the temperature is taken as the indoor environmental temperature Ti。
S203, if the indoor environment temperature TiIs greater than or equal to a first preset temperature T1Calculating the indoor ambient temperature TiWith a user-set temperature TdThe ratio of (A) to (B);
a first preset temperature T1For the temperature value pre-stored in the memory of the air conditioner, this temperature value may be significantly higher than the range of the temperature value set by the user, for example, a temperature value above 35 ℃, more specifically a temperature value above 35 ℃Of a first predetermined temperature T1It may be 38 ℃ or 36 ℃. When the air conditioner is started in a cooling mode, the indoor ambient temperature T is comparediAnd a first preset temperature T1If the indoor ambient temperature TiIs greater than or equal to a first preset temperature T1Then calculating the indoor ambient temperature TiWith a user-set temperature TdThe ratio of (a) to (b). If the indoor environment is less than the first preset temperature T1Then not calculating the indoor ambient temperature TiWith a user-set temperature TdThe ratio of (a) to (b).
Because, some users may have a habit of setting the temperature of the air conditioner to be low at the time of power-on, for example, 18 ℃ or 16 ℃. However, after the air conditioner is started for a period of time, the temperature on the remote controller is adjusted to be a common temperature such as 24 ℃ or 25 ℃ without reaching 18 ℃, for example, only about 24 ℃. If the indoor ambient temperature T is not changediAnd a first predetermined temperature T1In comparison, if the user performs the above setting, the cooling power of the air conditioner at the start stage is large, and the naturally required intake air amount of the indoor unit is also large. For example, the current indoor temperature is 33 ℃ or 34 ℃, and the proportional relation between the current indoor temperature and the set temperature is 18 ℃, which is about 1.8 or more, if the set proportion alpha is set to 1.5, the set proportion alpha is obviously exceeded, refrigeration is needed to be carried out with large refrigeration power, and the air flow of the indoor unit is large to transfer heat to the indoor coil, so that the temperature of the indoor coil is prevented from being too low, and the refrigeration capacity of the air conditioner is fully utilized. However, such a large cooling rate is not actually required, or the energy consumption required for such a large cooling rate is relatively large. So the application firstly carries out the indoor environment temperature TiAnd a first predetermined temperature T1In comparison, for example, in the above case, the current indoor temperature is 33 ℃ and less than 38 ℃, so the temperature is reduced at a speed slightly higher than the normal speed without using a very rapid temperature reduction method.
S205, adjusting the opening degree of the front panel grille according to the relation between the ratio and the set proportion alpha.
After the ratio is compared with the set ratio alpha, the opening degree of the front panel grating can be adjusted to a corresponding opening value so as to increase the air flow of the indoor unit and not obviously improve the indoor noise.
S206, specifically, the controlling the opening degree of the front grille according to the relationship between the ratio and the set ratio α includes: if the ratio is larger than or equal to the set ratio alpha, adjusting the front panel grille to a first opening degree; and if the ratio is smaller than the set ratio alpha, adjusting the front panel grille to a second opening degree, wherein the second opening degree is smaller than the first opening degree.
If the ratio is larger than or equal to the set ratio alpha, the compressor is also controlled to use the first preset frequency f1Operating, controlling the inner fan to rotate at a first preset rotating speed R1Operation, wherein the first preset frequency f1The operation frequency of the compressor in the power mode may be, for example, the maximum value of the allowable operation frequency range of the compressor, or more than 90% of the maximum value. And the first preset rotation speed R1The operating frequency of the indoor fan in the power mode may be, for example, the maximum speed allowed by the indoor fan, or more than 90% of the maximum speed. And adjusting the front panel grille to the first opening degree indicates that the front panel grille is in a fully open state. In addition, in this case, the air guiding door is also adjusted to the most smooth position, that is, the air guiding door has the minimum obstruction to the air outlet of the indoor unit, so that the air outlet of the indoor unit is smoother. When the indoor fan rotates at a first preset rotating speed R1At maximum speed, the compressor is operated at a first predetermined frequency f1The maximum frequency is in operation, the front panel grid is opened to the first opening degree, namely the fully open state, the refrigeration speed is fastest, the flow of the indoor unit of the air conditioner is maximum, and the temperature of the indoor environment can be reduced as soon as possible to be close to the temperature expected by a user.
If the ratio is less than the set ratio alpha, the compressor is also controlled to use the first preset frequency f1Operating, controlling the inner fan to rotate at a first preset rotating speed R1And (5) operating, and adjusting the front panel grille to a second opening degree. Still adjust the air guide door to the most in the same direction as the position, the air guide door hinders minimum state to the air-out of indoor set promptly to make the air-out of indoor set more smooth. Specifically, the second opening degree canThe opening degree of the front panel grille is 70% -90%, more specifically, 80% of the opening degree of the front panel grille. Since the indoor ambient temperature T is not higher than the set ratio α as in the case of the above-described ratioiBy this distance, the temperature in the room does not need to be regulated at a very high cooling rate, so that heat can be transferred to the indoor coil without using as large a ventilation area as described above and without using as large an air flow through the indoor unit.
By setting the indoor ambient temperature TiWith a user-set temperature TdThe ratio of the front panel grille to the indoor unit is compared with the set ratio alpha, so that when the temperature difference with the temperature required by a user is larger, the opening degree of the front panel grille can be increased, the ventilation area can be increased more, the ventilation quantity of the indoor unit can be improved, and the requirement of quickly reducing the temperature can be met.
The invention firstly carries out the indoor environment temperature TiAnd a first predetermined temperature T1By comparison, the indoor ambient temperature T can be determinediWhether it is absolutely overheated to determine whether it is really necessary to cause a significant increase in the ventilation of the indoor unit. Avoiding the simple dependence on the temperature T set by the userdIn the scheme for comparison, the user sets the temperature TdThe air volume of the indoor unit is increased when the air volume of the indoor unit is not required to be increased due to low air volume, so that energy waste is caused. Meanwhile, the opening degree of the front panel grating is increased, the ventilation area of the indoor unit can be increased, the operation speed of an indoor fan of the air conditioner is not required to be too high, and the noise of the indoor unit of the air conditioner can be reduced.
In a preferred embodiment, the control method further includes:
s207, if the front panel grid is in the first opening degree, and the indoor environment temperature T isiReduced to the user-set temperature TdAnd a first floating value DeltaT1If the front panel grille is not opened, adjusting the opening degree of the front panel grille to a fifth opening degree, wherein the fifth opening degree is smaller than the second opening degree; if the front panel grid is in the second opening degree and the air conditioner is in the indoor environment temperature TiReduced to the user-set temperature TdAnd a second floating value DeltaT2And adjusting the opening degree of the front panel to a fifth opening degree.
In particularWhen the indoor ambient temperature TiWith a user-set temperature TdWhen the ratio of (A) is greater than or equal to a set ratio alpha, the initial indoor environment temperature TiIf the front panel grille is opened in the fully open state, the front panel grille can no longer be fully open when the room temperature is reduced to a higher temperature. For example, the first floating value Δ T1And may be 6 c to 10 c, more specifically 8 c, i.e. if the user sets the temperature TdAt 25 c, the room temperature is reduced to 33 c and the front panel grid is no longer left fully open and is opened at a fifth opening. And the fifth opening degree may be 20% to 40% of the opening degree at the full opening, and more particularly, may be 30% of the opening degree, thereby reducing the air flow rate and reducing the power consumption.
When the indoor ambient temperature TiWith a user-set temperature TdIs less than the set ratio alpha, the initial indoor ambient temperature TiIf the front panel grill is opened at a large opening, the front panel grill is no longer in a state of a large opening when the room temperature is lowered to a temperature slightly higher than the set temperature. For example, the second floating value Δ T2And may be 2 c to 4 c, more specifically 3 c, i.e. if the user sets the temperature TdThe room temperature is reduced to 27 ℃ at 25 ℃, and the front panel grating is not opened by 30 percent, thereby reducing the air flow and reducing the energy consumption.
By adopting the technical scheme, the temperature T of the indoor environment can be controllediThe temperature section far away from the preset temperature is rapidly cooled to reduce the indoor dry heat feeling, and the temperature section near the preset temperature does not need the large indoor ventilation volume, so that the energy can be saved.
In a preferred embodiment, the control method further includes:
s209, triggering an anti-freezing protection condition, and if the starting time t of the air conditioner is less than a first preset time t1Closing the front grille and setting the operating frequency of the compressor from a first preset frequency f1Reduced to a second predetermined frequency f2(ii) a If the starting time t of the air conditioner is less than the second preset time t2And is not less thanA first preset duration t1And closing the front panel grille.
The condition for triggering the anti-freezing protection can be the temperature T of the indoor coil pipeRReduced to the anti-freezing protection trigger temperature TCThe temperature of the refrigerant flowing back from the indoor coil pipe or the air outlet temperature of the air conditioner can be monitored to judge whether the temperature reaches a certain preset temperature. The former is taken as an example for explanation in this embodiment.
If the indoor coil temperature TRReduced to the anti-freezing protection trigger temperature TCWhen the time is up, the starting time t is less than the first preset time t1The description shows that the air conditioner makes the indoor coil temperature T in a short timeRIf the temperature of the indoor unit is too low, the refrigerating power of the air conditioner should be reduced, and the flow of the refrigerant conveyed to the indoor coil pipe is reduced, so that the frequency of the compressor can be reduced, the flow of the refrigerant in a pipeline of the compressor is reduced, the refrigerating power is reduced correspondingly, the refrigerating power is reduced, the indoor unit does not need to output so much cold air, and the front panel grille can be closed. Wherein the second predetermined frequency f2May be a first predetermined frequency f175% -85% of the first preset frequency f, specifically, the first preset frequency f180% of the total.
If the indoor coil temperature TRReduced to the anti-freezing protection trigger temperature TCWhen the time is up, the starting time t is more than or equal to a first preset time t1And is less than a second preset time t2Then, the front panel grill can be simply closed without reducing the compressor frequency, so that the compressor frequency still maintains the first preset frequency f1。
When the anti-freezing protection condition is triggered, the ventilation quantity can be reduced in a mode of closing the grating, and energy waste is avoided. Especially when the air conditioner is started, the anti-freezing protection trigger temperature T is reached quicklyCIn the case of (3), the frequency of the compressor can be reduced to reduce the refrigerating power, so that the indoor unit does not need to exchange with the indoor coil pipe through as much air in unit time as the indoor unit originally, and the energy can be saved while the indoor coil pipe is prevented from freezing.
