Fig. 1 is a flowchart illustrating a method for controlling an outdoor unit according to the present invention. As shown in fig. 1, a method for controlling an outdoor unit according to an embodiment of the present invention includes: and step 101, obtaining air conditioner operation information.
The execution subject of the method for controlling an outdoor unit according to the embodiment of the present invention is a control device of the outdoor unit.
The application scenario of the control method of the outdoor unit provided by the embodiment of the invention is that after a user activates the working mode of the air conditioner, the temperature of the coil pipe and the temperature of the air outlet are simultaneously monitored through the sensing module, and the running frequency of the outdoor unit is adaptively adjusted, so that the actual load state in the working mode is close to the designed ideal value.
It should be noted that, before step 101, the user needs to send an activation command through the transmission medium to activate the operation mode of the air conditioner, and operate the air conditioner in the default fan speed and operation frequency in the operation mode.
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 air conditioner initializes the corresponding operating mode.
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 operating mode of the air conditioner after performing voice recognition.
Specifically, in step 101, after the air conditioner is started, the control device of the outdoor unit receives the operation information fed back by each component according to the activation instruction, and assembles the operation information of the air conditioner to represent the operation state of the air conditioner in a certain operation mode.
And 102, acquiring a first coil pipe temperature and a first outlet air temperature under the condition that the working mode is determined to be the refrigeration mode.
Wherein the operation mode is determined based on the air conditioner operation information.
Specifically, in step 102, the control device of the outdoor unit reversely parses the air conditioner operation information acquired in step 101, and determines the activated operation mode.
If the working mode is determined to be the refrigeration mode, in the same collection period, the control device of the outdoor unit receives the first coil pipe temperature collected by the sensing module arranged at the coil pipe, and meanwhile receives the first outlet air temperature collected by the sensing module arranged at the air outlet.
And the first coil temperature is used for representing the actual operation state of the evaporator under the action of the default operation frequency of the outdoor unit in the refrigeration mode.
And the first air outlet temperature is used for representing the temperature of the cold air generated by the evaporator in an actual operation state.
The embodiment of the invention does not specifically limit the working period of the sensing modules arranged at the coil pipe and the air outlet.
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 outdoor unit searches and interpolates the data to acquire a first coil pipe temperature and a first outlet air temperature at the same acquisition time.
Optionally, the user may change the working period to the period indicated by the instruction to perform the collecting operation by sending a period change instruction, and the sensing modules receive and respond to the instruction, so that the sensing modules at two positions simultaneously collect the first coil temperature and the first outlet air temperature at the same collecting time interval.
Specifically, in step 103, the control device of the outdoor unit compares the first coil temperature and the first outlet air temperature.
If the temperature of the first coil pipe is lower than the first air outlet temperature, that is, the outdoor unit generates less refrigerating capacity under the default operating frequency of the refrigerating mode, and when the evaporator performs heat exchange, the temperature of the first coil pipe is lower, so that the temperature of the output cold air is relatively higher, and indoor quick refrigeration and cooling cannot be performed. Therefore, the temperature of the coil pipe needs to be increased, conversion is performed according to the first coil pipe temperature and the first air outlet temperature, and the first target coil pipe temperature is obtained.
The first target coil temperature is a target value obtained by compensating the coil temperature when the actual refrigerating capacity meets the ideal refrigerating capacity requirement of the refrigerating mode.
If the temperature of the first coil pipe is greater than or equal to the first outlet air temperature, it is stated that the generated refrigerating capacity is enough to rapidly cool the indoor space under the default operating frequency of the outdoor unit in the refrigerating mode. Therefore, no compensation for coil temperature is required.
And 104, controlling the frequency of the outdoor unit to increase until the temperature of the coil pipe rises to a first target temperature of the coil pipe.
Specifically, in step 104, the control device of the outdoor unit packages the converted first target coil temperature into the frequency boost command, and distributes the frequency boost command to the outdoor unit.
The outdoor unit receives and responds to the frequency increasing instruction, and controls the internal compressor to increase the operating frequency, so that the temperature of the coil pipe of the indoor unit is correspondingly increased. When the temperature of the coil pipe is increased to the first target temperature of the coil pipe, a sensing module arranged at the coil pipe sends a signal to the outdoor unit to indicate that the current temperature of the coil pipe reaches the target value, and the running frequency can be stopped to continuously increase.
The higher the running frequency is, the higher the temperature of the coil pipe is, and the more the refrigerating capacity is, so that the refrigerating temperature is reduced, and the aim of quickly refrigerating and cooling is fulfilled.
According to the embodiment of the invention, based on the comparison and analysis of the first coil pipe temperature and the first air outlet temperature in the refrigeration mode, when the decision is made to increase the refrigeration capacity, the first target coil pipe temperature is calculated to control the outdoor unit to dynamically adjust the operation frequency, so that the average performance of each branching effect of the indoor unit is reflected according to the coil pipe temperature and the air outlet temperature, the real refrigeration state can be reflected, an accurate basis is provided for the subsequent intelligent refrigeration adjustment, and the refrigeration performance is improved.
On the basis of any one of the above embodiments, determining a first target coil temperature based on the first coil temperature and the first outlet air temperature under the condition that it is determined that the first coil temperature is less than the first outlet air temperature includes: based on the first coil temperature and the first outlet air temperature, a first temperature difference is determined.
Specifically, in step 103, the control device of the outdoor unit performs a difference between the first outlet air temperature and the first coil temperature to obtain a first temperature difference.
A second temperature difference is determined based on the current room temperature and the first target room temperature.
Wherein the first target room temperature is an optimum cooling temperature in the cooling mode.
The first target room temperature is an optimum cooling temperature in the cooling mode.
The value of the first target room temperature is not particularly limited in the embodiment of the present invention.
Illustratively, the first target room temperature may be an optimal refrigeration temperature specified in the industry, and may be, for example, 26 ℃.
For example, the first target room temperature may be a cooling temperature set by a user in an activation instruction to turn on the cooling mode.
Specifically, since the current first outlet air temperature is slightly higher than the first coil temperature, which indicates that the current indoor temperature has not decreased to the first target room temperature, the control device of the outdoor unit performs a difference between the current indoor temperature and the first target room temperature to obtain a second temperature difference.
A first target coil temperature is determined based on the first coil temperature, the first temperature differential, and the second temperature differential.
Specifically, the control device of the outdoor unit substitutes the first coil temperature, the first temperature difference, and the second temperature difference into the mathematical model to calculate the first target coil temperature.
The calculation process of the first target coil temperature is not particularly limited in the embodiment of the present invention.
For example, the first target coil temperature may be calculated as:
D 1 ＝Tw 1 -Tp 1
D 2 ＝T-T 1
wherein,
for a first target coil temperature, tp 1 Is the first coil temperature.
D 1 Is a first temperature difference with a first outlet air temperature Tw 1 And a first coil temperature Tp 1 The difference between them.
D 2 Is a second temperature difference having a value of the current room temperature T and the first target room temperature T 1 The difference between them.
k 1 And k 2 All are weight parameters, the value range of which is between 0 and 1, and k 1 And k is 2 The sum is 1.
Example pair k of the present invention 1 And k 2 The value is not particularly limited. Illustratively, since the operating frequency has a large effect on coil temperature, k will be 1 Is set to 0.9,k 2 Set to 0.1.
According to the embodiment of the invention, when the refrigerating capacity is decided to be increased, the sensible heat compensation quantity of the evaporator when the indoor unit operates is reflected through the first difference value, the latent heat compensation quantity of the evaporator in the indoor environment is reflected through the second difference value, and then the first target coil temperature is converted on the basis of the first coil temperature so as to control the outdoor unit to dynamically adjust the operation frequency, so that the average performance of each branch effect of the indoor unit is reflected according to the coil temperature and the air outlet temperature, the real refrigerating state can be reflected more effectively, an accurate basis is provided for the subsequent intelligent refrigeration adjustment, and the refrigerating performance is improved.
On the basis of any one of the above embodiments, after acquiring the air conditioner operation information, the method further includes: and under the condition that the working mode is determined to be the heating mode, acquiring the temperature of the second coil pipe and the temperature of the second air outlet.
Wherein the operation mode is determined based on the air conditioner operation information.
Specifically, after step 101, the control device of the outdoor unit reversely parses the air conditioner operation information acquired in step 101, and determines the activated operation mode.
If the working mode is determined to be the heating mode, in the same collection period, the control device of the outdoor unit receives the temperature of the second coil pipe collected by the sensing module arranged at the coil pipe, and meanwhile receives the temperature of the second air outlet collected by the sensing module arranged at the air outlet.
And the second coil temperature is used for representing the actual operation state of the evaporator under the action of the default operation frequency of the outdoor unit in the heating mode.
And the second air outlet temperature is used for representing the temperature of the hot air generated by the evaporator in an actual operation state.
And under the condition that the second coil temperature is determined to be greater than the second outlet air temperature, determining a second target coil temperature based on the second coil temperature and the second outlet air temperature.
Specifically, the control device of the outdoor unit compares the temperature of the second coil with the second outlet air temperature.
If the temperature of the second coil is higher than the second air outlet temperature, it is described that the generated heating amount is more and the evaporator is overloaded under the default operating frequency of the outdoor unit in the heating mode, and the temperature of the second coil is higher, so that the temperature of the output hot air is relatively higher, and the requirement of heating and warming indoors is met. Therefore, the temperature of the coil pipe needs to be reduced, and then conversion is performed according to the temperature of the second coil pipe and the second outlet air temperature to obtain a second target coil pipe temperature.
The second target coil temperature is a target value obtained by reducing the coil temperature when the actual heating capacity already meets the ideal heating capacity requirement of the heating mode.
If the temperature of the second coil is less than or equal to the second outlet air temperature, it is stated that the generated heating amount still fails to raise the indoor temperature to the target temperature or just reaches the target temperature under the default operating frequency of the outdoor unit in the heating mode. Therefore, the temperature of the coil does not need to be reduced.
And controlling the outdoor unit to reduce the frequency until the temperature of the coil pipe is reduced to a second target temperature of the coil pipe.
Specifically, the control device of the outdoor unit packages the converted second target coil temperature into a frequency reduction command, and distributes the frequency reduction command to the outdoor unit.
The outdoor unit receives and responds to the frequency reduction instruction, and controls the compressor in the outdoor unit to reduce the operating frequency, so that the temperature of the coil pipe of the indoor unit is correspondingly reduced. When the temperature of the coil pipe is reduced to a second target coil pipe temperature, a sensing module arranged at the coil pipe sends a signal to the outdoor unit so as to indicate that the current temperature of the coil pipe reaches a target value, and the running frequency can be stopped to continue to be reduced.
Wherein, the lower the operating frequency, the lower the coil pipe temperature, the less the heating capacity to make the heating temperature reduce thereupon, realize when the current heating effect satisfies the demand of heating, weakening the heating effect.
According to the embodiment of the invention, based on the comparison and analysis of the second coil pipe temperature and the second air outlet temperature in the heating mode, when the heating quantity is reduced, the second target coil pipe temperature is calculated to control the outdoor unit to dynamically adjust the operation frequency, so that the average performance of each branch effect of the indoor unit is reflected according to the coil pipe temperature and the air outlet temperature, the real heating state can be reflected, an accurate basis is provided for the subsequent intelligent heating adjustment, the refrigerating performance is improved, and the energy efficiency waste is avoided.
On the basis of any of the above embodiments, determining a second target coil temperature based on the second coil temperature and the second outlet air temperature under the condition that the second coil temperature is determined to be greater than the second outlet air temperature includes: and determining a third temperature difference based on the second coil temperature and the second outlet air temperature.
Specifically, the control device of the outdoor unit performs a difference operation by using the temperature of the second coil and the second outlet air temperature, and obtains a third temperature difference.
A fourth temperature difference is determined based on the current room temperature and a second target room temperature.
