As shown in fig. 1, a control method for a fresh air conditioner according to an embodiment of the present invention includes: step 101, acquiring an environment temperature difference based on a first environment temperature and a second environment temperature.
The first environment temperature is the indoor temperature collected by the fresh air fan under the target gear, and the second environment temperature is the outdoor temperature collected by the fresh air fan under the target gear. The target gear is one of the wind speed gears of the fresh air fan.
The main execution body of the control method of the fresh air conditioner provided by the embodiment of the invention is a control device of the fresh air conditioner.
The control method of the fresh air conditioner provided by the embodiment of the invention is applied in the scene that the fresh air conditioner simultaneously monitors indoor and outdoor temperatures through the sensing module when a corresponding working mode is started, and adaptively compensates the rotating speed of the fresh air fan, so that the refrigeration/heat effects are accelerated and averaged in an indoor space for subsequent intelligent temperature regulation.
The first environmental temperature refers to temperature information monitored indoors periodically by a sensing module arranged in an indoor unit at a specified time interval in the process that a fresh air fan operates at a target gear.
The second ambient temperature is temperature information that is set in the process that the fresh air fan runs at a target gear and is periodically monitored outdoors by a sensing module set in the outdoor unit at a specified time interval.
The target gear refers to a gear corresponding to an activation instruction for starting the fresh air conditioner by a user in a plurality of preset wind speed gears of a fresh air fan of the indoor unit.
The number of the wind speed gears preset by the fresh air fan is not specifically limited in the embodiment of the invention.
Illustratively, according to the standard in the industry, the fresh air fan generally presets three wind speed gears, namely a low gear, a medium gear and a high gear, and the rotating speed values corresponding to the gears are sequentially increased.
The working cycles of the sensing modules respectively arranged in the indoor unit and the outdoor unit are not particularly limited in the embodiment of the invention.
Optionally, the sensing modules at both locations may perform the collection operation in a default duty cycle. After receiving the sensing information periodically acquired by the two sensing modules, the control device of the fresh air conditioner searches and interpolates the data to acquire a first ambient temperature and a second ambient temperature at the same acquisition time.
Optionally, the user may send a cycle change instruction, and each sensing module receives and responds to the instruction, and changes the working cycle to the cycle indicated by the instruction to perform the collection operation, so that the sensing modules at two locations simultaneously collect the first ambient temperature and the second ambient temperature at the same collection time interval.
It should be noted that, before step 101, a user needs to send an activation instruction through a transmission medium to activate the fresh air conditioner, so that a fresh air fan of the fresh air conditioner operates at a default gear rotation speed, and an outdoor unit of the fresh air conditioner operates at a default operating frequency.
Optionally, the user may transmit the activation instruction through the control device in a wireless communication manner between the control device and the air conditioning system, so that the fresh air fan of the fresh air conditioner operates at a default gear rotation speed, and the outdoor unit of the fresh air conditioner operates at a default operating frequency.
Optionally, the user may send an activation instruction in a voice interaction manner, and the air conditioning system receives the activation instruction and initializes the fresh air conditioner after performing voice recognition.
Specifically, in step 101, after determining that the fresh air fan operates at a target gear according to the operation information fed back by each component according to the activation instruction, the control device of the fresh air conditioner receives the sensing modules in the indoor unit and the outdoor unit, respectively collects the first temperature information and the second temperature information in the respective current working periods, makes a difference between the first temperature information and the second temperature information, and takes an absolute value of the difference as an environmental temperature difference.
And 102, determining a target rotating speed value based on the current gear rotating speed of the fresh air fan and the environmental temperature difference.
And the current gear rotating speed is the fan rotating speed corresponding to the target gear.
Specifically, in step 102, the control device of the fresh air conditioner determines the rotation speed compensation amount corresponding to the current indoor and outdoor temperature difference by combining the corresponding relationship between the environmental temperature difference and the rotation speed compensation amount, and obtains the target rotation speed value by combining the rotation speed compensation amount on the basis of the current gear rotation speed corresponding to the target gear.
The embodiment of the invention does not specifically limit the corresponding relationship between the environmental temperature difference and the rotational speed compensation amount.
For example, the correspondence between the ambient temperature difference and the rotation speed compensation amount may be a linear relationship in a one-to-one correspondence. Therefore, the rotating speed compensation amount corresponding to the current environment temperature difference is combined with the current gear rotating speed to convert a target rotating speed value.
And 103, controlling the indoor unit to adjust the rotating speed of the fan according to the target rotating speed value.
Specifically, in step 103, the control device of the fresh air conditioner packages the target rotation speed value obtained in step 102 into a speed-up command, and sends the speed-up command to the indoor unit.
The indoor unit receives and responds to the speed increasing instruction, and controls a fan inside the indoor unit to adjust the rotating speed of the fan on the basis of the current default rotating speed according to the target rotating speed value indicated in the instruction.
According to the embodiment of the invention, the environment temperature difference is obtained based on the indoor and outdoor first environment temperature and the second environment temperature, the target rotating speed value is determined through the environment temperature difference and the current gear rotating speed, the indoor fan is controlled to dynamically adjust the operating rotating speed, analysis is realized according to the indoor and outdoor environment temperature difference, the room temperature change caused by introducing fresh air from the outdoor is correspondingly compensated by adjusting the rotating speed of the indoor unit for conveying cold/hot air, and the indoor refrigerating/heating effect is not weakened.
On the basis of any one of the above-mentioned embodiments, based on the current gear rotational speed and the environmental temperature difference of new trend fan, confirm the target rotational speed value, include: and acquiring a first compensation coefficient corresponding to the first target subinterval according to the first target subinterval corresponding to the environment temperature difference.
The first target subinterval is obtained by performing interval division on the normal temperature difference interval.
It should be noted that the control device of the fresh air conditioner is provided with N in the normal temperature difference interval in advance 1 Dividing points to obtain N 1 +1 subintervals.
Wherein N is 1 Is a positive integer greater than or equal to 1. Each subinterval is provided with a different first compensation coefficient. And each first compensation coefficient is greater than or equal to 1, and the value of the first compensation coefficient increases with the increase of the upper limit value of the corresponding subinterval.
Specifically, in step 102, the control device of the fresh air conditioner uses a sub-interval where the environmental temperature difference is located as a first target sub-interval, and obtains a first compensation coefficient corresponding to the sub-interval.
And determining a target rotating speed value based on the current gear rotating speed and the first compensation coefficient.
Specifically, the control device of the fresh air conditioner multiplies the current gear rotating speed and a first compensation coefficient to obtain a target rotating speed value.
The division of the normal temperature difference region is not particularly limited in the embodiments of the present invention.
Exemplarily, in N 1 As an example, the normal temperature difference interval is divided into 3 first target subintervals, namely [0,5), [5,10), and [10, + ∞), where:
if the environmental temperature difference is in the first target subinterval [0,5 ], the first compensation coefficient k is determined 1 Set to 1.05, the target speed value is calculated as follows:
V targe ＝k 1 *V
wherein, V targe And V is the rotating speed of the current gear.
If the environmental temperature difference is in the first target subinterval [5,10 ], the first compensation coefficient k is determined 1 The rotating speed is set to be 1.1, so that the target rotating speed value for conveying cold/hot air is slightly higher than the current gear rotating speed for conveying fresh air.
If the ambient temperature difference is within the first target sub-interval [10, + ∞), the first compensation factor k is determined 1 The rotating speed of the current gear for conveying the fresh air is obviously increased compared with the rotating speed of the target rotating speed for conveying the cold/hot air which is set to be 1.2.
According to the embodiment of the invention, the first compensation coefficient is determined based on the subinterval where the environment temperature difference is located, and the target rotating speed value is converted through the first compensation coefficient and the current gear rotating speed, so that the indoor fan can increase the rotating speed to the target rotating speed value. The corresponding quantitative adjustment is determined according to the environment temperature difference, the corresponding rotating speed is increased, the quantity of cold/hot air output in unit time is increased, the corresponding compensation is carried out on the change of the room temperature caused by introducing fresh air from the outdoor, and the indoor refrigerating/heating effect is not weakened.
On the basis of any of the above embodiments, obtaining a first compensation coefficient corresponding to a first target subinterval according to the first target subinterval corresponding to the environmental temperature difference includes: and obtaining a conversion coefficient corresponding to the first target subinterval according to the first target subinterval corresponding to the environment temperature difference.
It should be noted that the control device of the fresh air conditioner is divided into N in advance in the normal temperature difference interval 1 +1 subintervals, different conversion coefficients are set accordingly. And the number of the first and second electrodes,each conversion coefficient is greater than or equal to 1, and the value thereof increases as the upper limit value of the corresponding subinterval increases.
Specifically, the control device of the fresh air conditioner takes the subinterval where the environmental temperature difference is located as a first target subinterval, and obtains the conversion coefficient corresponding to the subinterval.
And determining a first compensation coefficient based on the conversion coefficient and the fresh air ratio.
The fresh air ratio is determined based on the current gear rotating speed.
The fresh air ratio is a ratio of fresh air volume entering from the outdoor to cold/hot air volume generated by the indoor unit.
The embodiment of the invention does not specifically limit the calculation mode of the fresh air ratio.
Illustratively, the calculation formula of the fresh air ratio a can be as follows:
wherein, V r The rated rotating speed of the fresh air fan is set,
the rated air quantity of the fresh air fan,
the rated air supply quantity of the indoor unit of the air conditioner.
Specifically, the control device of the fresh air conditioner substitutes the conversion coefficient and the fresh air ratio into the mathematical model to calculate the first compensation coefficient.
First compensation coefficient k 1 The specific calculation formula is as follows:
k 1 ＝b+a
wherein b is a conversion coefficient corresponding to the environmental temperature difference, and the value thereof is not particularly limited in the embodiment of the present invention.
Illustratively, if the ambient temperature difference is in the first target subinterval [0,5), then the conversion coefficient is set to b to 1.05.
If the ambient temperature difference is in the first target subinterval [5,10), the conversion coefficient b is set to 1.1.
If the ambient temperature difference is in the first target subinterval [10, + ∞), then the conversion factor b is set to 1.2.
The embodiment of the invention determines the conversion coefficient based on the subinterval where the environment temperature difference is located, and converts the conversion coefficient and the fresh air ratio of the fresh air fan at the current gear rotating speed into the first compensation coefficient for calculating the target rotating speed value. The corresponding adjustment magnitude is determined according to the environment temperature difference, the rotating speed of the fan is increased to the corresponding target value, the quantity of cold/hot air output in unit time is increased, the corresponding compensation is carried out on the room temperature change caused by introducing fresh air from the outdoor, and the indoor refrigeration/heat effect is not weakened.

And the current gear rotating speed is the fan rotating speed corresponding to the target gear.
It should be noted that the preset threshold refers to a target value set for the rotation speed of the fresh air fan. For example, the preset threshold may be set to a rotation speed value corresponding to a high gear, and is used for indicating the fan operation intensity.
Specifically, the control device of the fresh air conditioner compares the current gear rotating speed of the fresh air fan with a preset threshold value.
If the current gear rotating speed of the fresh air fan is larger than or equal to the preset threshold value, the operation intensity of the fresh air fan which is originally activated by a user reaches a high-speed gear or above, if the rotating speed is continuously increased to increase the fresh air quantity, the evaporator is caused to operate at the default operation frequency, the heat exchange efficiency is reduced, and the control device of the fresh air conditioner is required to determine the target rotating speed value corresponding to the current indoor and outdoor temperature difference on the basis of the current gear rotating speed by combining the corresponding relation between the environmental temperature difference and the rotating speed. And determining a target frequency change value corresponding to the current indoor and outdoor temperature difference by combining the corresponding relation between the environmental temperature difference and the operating frequency.

Specifically, the control device of the fresh air conditioner packages the converted target rotating speed value and the target frequency change value into a speed increasing instruction and a frequency increasing instruction respectively, and distributes the two instructions to the indoor unit and the outdoor unit.
The indoor unit receives and responds to the speed increasing instruction, and controls the fresh air fan inside the indoor unit to adjust the rotating speed of the fan on the basis of the current gear rotating speed according to the target rotating speed value indicated in the instruction.
And the outdoor unit receives and responds to the frequency increasing instruction, and controls the internal compressor to adjust the operating frequency on the basis of the default operating frequency of the current gear according to the target operating frequency indicated in the instruction.

if the ambient temperature difference is in the second target subinterval [0,5 ], the corresponding target frequency variation value is set to +10 hertz (Hz), the conversion coefficient b is set to 1.05, and the calculation formula of the target rotation speed value is as follows:
