The air quantity adjusting method of the auxiliary heating air conditioner can be executed by a controller of the air conditioner, a control panel in communication connection with the air conditioner and a server in communication connection with the air conditioner.
Referring to fig. 2, the method for adjusting the air volume of the auxiliary air conditioner includes:
s201, in the auxiliary heating mode, the on-off state of the electric heating device is obtained.
The auxiliary heating air conditioner comprises an auxiliary heating mode and a non-auxiliary heating mode, and is operated in the non-auxiliary heating mode under the condition that the indoor temperature is not too low, for example, the indoor temperature is higher than the set lower limit environment temperature, and the auxiliary heating air conditioner heats the indoor air through the condenser; in case the indoor temperature is too low, for example, the indoor temperature is less than the set lower limit ambient temperature, the auxiliary heating air conditioner is operated in the auxiliary heating mode, and at this time, the auxiliary heating air conditioner heats the indoor air through the condenser and the electric heating device.
Alternatively, a user instruction may be received and a secondary or non-secondary mode entered in response to the user instruction.
The on-off state of the electric heating device can be determined by obtaining the on-off state of the relay for the on-state of the operating current for the electric heating device. Or detecting the working current of the auxiliary heating air conditioner, and determining that the electric heating device is switched from the power-off state to the power-on state under the condition that the running state (the running state such as the compressor frequency, the indoor fan rotating speed, the outdoor fan rotating speed and the like) of the auxiliary heating air conditioner is unchanged and the working current of the air conditioner rises in a step-type manner.
S202, under the condition that the electric heating device is not switched from the power-off state to the power-on state for the first time, the current air output and the air output compensation quantity of the air conditioner indoor unit are obtained.
In the embodiment of the present application, the air volume refers to the flow rate of air in a unit time, for example, the current air output volume and the air volume compensation volume may be in units of cubic meters per second.
Under the condition that the auxiliary heating air conditioner enters the auxiliary heating mode for the first time, the electric heating device is switched from the power-off state to the power-on state for the first time, and at the moment, two conditions exist: in the first case, the air quantity of the air conditioner makes the heat dissipation rate of the electric heating device equal to the heating rate of the electric heating device; in the second case, the air volume of the air conditioner makes the heat radiation rate of the electric heating device small as the heating rate of the electric heating device. The second condition may be caused by a low rotation speed of the air conditioner or by serious filter clogging of the indoor unit of the air conditioner.
In the second case, the temperature of the electric heating device will continuously rise until the corresponding temperature protection device of the electric heating device triggers overheat protection, so that the electric heating device is switched from the power-on state to the power-off state. And then the temperature of the electric heating device continuously drops until the temperature of the electric heating device is lower than or equal to the deprotection temperature, and the electric heating device is switched from the power-off state to the power-on state. The switching process is that the electric heating device is switched from the power-off state to the power-on state for the second time under the auxiliary heating mode. In the switching process from the power-off state to the power-on state after the current time, the electric heating device is not switched from the power-off state to the power-on state for the first time.
The current air output of the air conditioner indoor unit can be represented by the rotating speed of a fan of the air conditioner indoor unit and/or the opening degree of an air deflector; thus, obtaining the current air output of the indoor unit of the air conditioner may include: and obtaining the current fan rotating speed of the air conditioner indoor unit and/or the current air deflector opening of the air conditioner indoor unit.
The air volume compensation amount may be preset; when the current air output is represented by the current fan speed, the air volume compensation amount may be a preset fan speed, for example, the preset fan speed may be 1/10, 1/9, 1/8, 1/7, 1/6, 1/5 or 1/4 of the maximum fan speed of the indoor unit of the air conditioner; when the current air outlet opening represents the current air outlet amount, the air volume compensation amount may be a preset air guide opening, for example, the preset air guide opening may be 1/10, 1/9, 1/8, 1/7, 1/6 or 1/5 of the maximum air guide opening of the indoor unit of the air conditioner; under the condition that the current wind output is represented by the current fan rotating speed and the current wind deflector opening, the wind volume compensation quantity can be preset fan rotating speed and/or preset wind deflector opening, and the preset fan rotating speed and the preset wind deflector opening are set according to the above.
Alternatively, the air volume compensation is calculated, for example, obtaining an air volume compensation amount may include: obtaining the duration of heating of the electric heating device between the power-off state and the power-on state of the electric heating device at the last time; obtaining the power-off time length of the electric heating device between the power-on state and the power-off state of the electric heating device at the last time; and obtaining the air quantity compensation quantity which is inversely related to the continuous heating time and positively related to the power-off time.
The heat dissipation rate improvement quantity required by the electric heating device is measured by utilizing the continuous heating time and the outage time, so that the air quantity compensation quantity can meet the heat dissipation requirement of the electric heating device as much as possible, the heating effect of the Gao Fu heat air conditioner is improved, the numerical value of the air quantity compensation quantity can be reduced as much as possible, and the discomfort brought to a user by the improvement of the air quantity is reduced. In the embodiment of the application, the continuous heating duration can reflect the difference rate between the heating rate and the heat dissipation rate of the electric heating device, and the longer the continuous heating duration is, the smaller the difference rate is, the shorter the continuous heating duration is, and the larger the difference rate is; the power-off duration can reflect the heat dissipation rate of the electric heating device, and the longer the power-off duration is, the smaller the heat dissipation rate of the electric heating device is, and the longer the power-off duration is, the greater the heat dissipation rate of the electric heating device is. The electric heating device is not switched from the power-off state to the power-on state for the first time, which means that the heat dissipation rate of the electric heating device cannot meet the heat dissipation requirement of the electric heating device at the moment, the heat dissipation rate of the electric heating device needs to be improved, the air quantity compensation quantity is positively related to the power-off time, and the air quantity can be further improved so as to improve the heat dissipation rate of the electric heating device as soon as possible; the air quantity compensation quantity is inversely related to the duration of continuous heating, the air quantity is increased at a relatively slow increasing rate, and discomfort brought to a user due to the increase of the air quantity is reduced as much as possible. Finally, the technical scheme in the embodiment of the application not only can ensure that the air quantity compensation quantity meets the heat dissipation requirement of the electric heating device as much as possible, but also can reduce the numerical value of the air quantity compensation quantity as much as possible so as to reduce the discomfort brought by the improvement of the air quantity to a user.
In some application scenarios, recording a time when the electric heating device is switched from the power-off state to the power-on state as a first time; then the electric heating device is electrified to operate, and as the heat dissipation rate of the electric heating device is lower than the heating rate of the electric heating device, at a certain moment, the electric heating device is switched from an electrified state to a power-off state, and the moment is recorded as a second moment; then the electric heating device is in a power-off state, and at another moment, the electric heating device is switched from the power-off state to the power-on state again as the temperature of the electric heating device gradually decreases, and the moment is recorded as a third moment. Thus, the continuous heating time length can be obtained by subtracting the first time from the second time; and subtracting the second time from the third time to obtain the power-off time.
Specifically, the quantitative air volume compensation amount can be obtained by: obtaining a first product of a power-off duration and a continuous heating duration, and the ratio and the current air output; and determining the air quantity compensation quantity according to the first product.
Wherein, determining the air volume compensation amount according to the first product may include: determining the first product as an air quantity compensation quantity; or, determining the second product of the first product and the protection coefficient as the air quantity compensation quantity; wherein the protection factor is less than 1.
The protection coefficient is used for adjusting the magnitude of the air volume compensation amount as a whole, and in specific applications, the protection coefficient can be appropriately increased if the electric heating device is frequently switched between an on state and an off state; if the air volume is excessively large after the air volume is adjusted, and the user feels uncomfortable, the protection coefficient can be properly reduced. Therefore, through the balance adjustment function of the protection coefficient, the auxiliary heating air conditioner can maintain a better heating effect, and meanwhile, a user can have better blowing experience.
And S203, adjusting the air output of the air conditioner indoor unit according to the sum of the air output compensation quantity and the current air output.
For example, the current air output of the air conditioner indoor unit can be increased by an air output compensation amount, namely, the air output of the air conditioner indoor unit is adjusted to be the sum of the air output compensation amount and the current air output.
In the specific adjustment process, if the air quantity compensation quantity is represented by the preset fan rotating speed, the fan rotating speed of the air conditioner indoor unit is increased, for example, the current fan rotating speed of the air conditioner indoor unit is increased by the preset fan rotating speed; if the air quantity compensation quantity is represented by the preset air guide plate opening, the air guide plate opening of the air conditioner indoor unit is improved, for example, the current air guide plate opening of the air conditioner indoor unit is improved by the preset air guide plate opening; if the air quantity compensation quantity is represented by the preset fan rotating speed and the preset air deflector opening, the fan rotating speed and/or the air deflector opening of the air conditioning indoor unit are/is increased, for example, the current fan rotating speed of the air conditioning indoor unit is increased by the preset fan rotating speed, or the current air deflector opening of the air conditioning indoor unit is increased by the preset air deflector opening, or the current fan rotating speed of the air conditioning indoor unit is increased by the preset fan rotating speed, and meanwhile the current air deflector opening of the air conditioning indoor unit is increased by the preset air deflector opening.
Under the condition that the electric heating device is overheated, the on-off state of the electric heating device is switched from the on-state to the off-state, and the overheat state of the electric heating device is monitored by utilizing the temperature protector of the electric heating device, so that the air quantity of the indoor unit of the air conditioner is improved, and the electric heating device achieves a good heating effect; the hardware relied by the process of improving the heating effect is the default hardware of the conventional air conditioner, and additional hardware such as a temperature sensor and the like is not required to be arranged on the indoor unit of the air conditioner, so that the production cost of the air conditioner is reduced.
