Fig. 3 is a photovoltaic air conditioner according to an embodiment of the present invention.
The problem that when an existing photovoltaic air conditioner is installed, the number of the main machines 2 and the proper number of the auxiliary machines 4 are difficult to select according to the actual situation of a house, and a current transformation system needs to be installed on the auxiliary machines 4, so that the cost is increased is solved. The scheme provides a control method of a photovoltaic air conditioner, which is applied to the photovoltaic air conditioner shown in figure 3, wherein a host 2 and a slave 4 respectively receive control signals sent by a user side, the control signals are uniformly transmitted to a variable current controller 3 from the host 2, the variable current controller 3 supplies power to the host 2, and the slave 4 needs to forward direct current through the host 2. Therefore, the number of the master machines 2 and the number of the slave machines 4 are selected according to the actual situation of the house, the slave machines 4 do not need to be provided with the converter controllers 3, the use cost can be greatly reduced, and the house can be installed before and after decoration, so that the whole photovoltaic air conditioner is very convenient to install and flexible to use, the installation cost of the whole photovoltaic air conditioner is reduced, and the application range of the photovoltaic air conditioner is enlarged.
The photovoltaic air conditioner comprises a variable flow controller 3, a host machine 2 and a slave machine 4, wherein the host machine and the slave machine are combined to form an air conditioning system, and for example, a control method is executed through application software installed in the photovoltaic air conditioner.
The converter controller 3 establishes signal transmission connection with the host 2, and the host 2 establishes signal transmission connection with the slave 4. Specifically, the converter controller 3 and the master 2 both have a communication function, the converter controller 3 receives various data messages transmitted from the master 2, the master 2 and the slave 4 also have a communication function, the master 2 receives various data messages transmitted from the slave 4, and then the data messages are transmitted to the converter controller 3. And the signal transmission in this embodiment connects can be based on connection technologies such as 485 communication, direct current carrier communication, bluetooth communication, WIFI communication and zero live wire and realize.
According to a specific implementation process of a control method of a photovoltaic air conditioner, as shown in fig. 1, the control method specifically includes:
s110, receiving the first required function information and the second required function information transmitted from the host 2.
Since the slave 4 cannot be used alone as an air conditioner, it is necessary to transmit various kinds of required function information to the master 2. The second required function information required by the user is transmitted to the host 2, the host 2 collectively transmits the first required function information and the second required function information to the variable flow controller 3, and the use requirement of the user side is determined by receiving the obtained first required function information and the second required function information. The user end of this embodiment is specifically a remote controller or a mobile end on which corresponding control software is installed.
For example, the user side needs are related usage needs for starting the air conditioning system to provide cooling capacity or heating capacity indoors, or for starting the air conditioning system to provide dehumidification or air supply indoors, and the like, and after the actual usage needs of the user are determined, the corresponding operation instructions are transmitted to the host 2, and the corresponding power supply is output to the host 2, and the host 2 performs the functions of providing cooling capacity, heating capacity, dehumidification or air supply and the like according to the operation instructions and the received power supply.
And S120, generating a first operation instruction and a second operation instruction which respectively correspond to the first requirement function information and the second requirement function information.
And the variable flow controller 3 controls the host machine 2 to perform the functions of providing cold, heat, dehumidification or air supply and the like according to the first operation instruction, and controls the slave machine 4 to perform the functions of providing cold, heat, dehumidification or air supply and the like according to the second operation instruction.
Specifically, if the first required function information is the function information for providing cooling capacity, the variable flow controller 3 generates an operation instruction requiring the host 2 to execute the cooling capacity providing function according to the function information for providing cooling capacity, so as to control the host 2 to execute the cooling capacity providing function, that is, the cooling function. If the second required function information is function information for providing heat, the variable flow controller 3 generates an operation instruction for the slave 4 to perform a heat providing function according to the function information for providing heat, so as to control the slave 4 to perform a heat providing function, that is, a heat generating function.
In addition, before the slave 4 performs the function of providing heat, because the variable current controller 3 is disposed in the master 2, when the variable current controller 3 controls the slave 4 to perform the function of the corresponding operation instruction, the variable current controller needs to transmit the first operation instruction and the second operation instruction to the master 2 at the same time, after receiving the first operation instruction and the second operation instruction, the master 2 executes the corresponding function according to the first operation instruction, then transmits the second operation instruction to the slave 4 through the master 2, and the slave 4 receives the second control instruction and executes the corresponding function according to the second operation instruction.
S130, generating a first power supply instruction and a second power supply instruction corresponding to the first operation instruction and the second operation instruction respectively.
Specifically, the electric quantity required by the master machine 2 and the slave machine 4 during operation is provided by the variable current controller 3, and as the direct current value required by the first operation instruction and the direct current value required by the second operation instruction need to be determined, according to the functional requirement of the first operation instruction, the first power supply instruction corresponding to the first operation instruction is generated, and the proper direct current value is determined according to the first power supply instruction; and generating a second power supply instruction corresponding to the first operation instruction according to the function requirement of the second operation instruction, and determining a proper direct current value according to the second power supply instruction.
For example, according to the functional requirement of the first operation instruction, the actual required dc value of the generated first power supply instruction is 200V, and then 200V is used as the dc value required to be output by the first power supply instruction; similarly, according to the functional requirement of the second operation instruction, the actual required dc value of the generated second power supply instruction is 200V, and then 200V is used as the dc value required to be output by the second power supply instruction.
In addition, since the dc values required by different required functions are different, the corresponding power supply commands generated when different operation commands are obtained are also different. For example, when providing functions such as cooling or heating, the required output dc value is large and can be set to 200V or more, and when providing functions such as dehumidification or air blowing, the required output dc value is small compared to the functions such as cooling or heating, and can be set to about 200V.
S140, transmitting the first power supply command to the host 2, and outputting a dc power value corresponding to the first power supply command.
Specifically, when the dc value required by the first power supply instruction is determined, the first power supply instruction is transmitted to the host 2, and the ac controller 3 outputs the dc value corresponding to the first power supply instruction to the host 2, at this time, the host 2 starts to execute the corresponding function according to the received first power supply instruction.
For example, if the first operation command is an operation command for providing cooling capacity, a first power supply command with a dc value of 300V is generated according to the first operation command, and then the first operation command is transmitted to the host 2, so as to start the host 2 to perform the cooling capacity providing function and supply power to the host 2, and output a dc value of 300V.
And S150, forwarding the second power supply instruction to the slave 4 through the master 2, and outputting a direct current value corresponding to the second power supply instruction.
Specifically, since the inverter controller 3 is not installed in the slave 4, the slave 4 only has an air conditioning system and cannot independently supply power, and the power needs to be output to the slave 4 by the master 2, and the power can be forwarded and output only by the master 2. Firstly, the converter controller 3 transmits a first power supply instruction and a second power supply instruction to the master machine 2 at the same time, then the master machine 2 transmits the second power supply instruction to the slave machine 4 while executing the function of providing cooling capacity, the master machine 2 transmits and outputs a direct current value corresponding to the second power supply instruction to the slave machine 4, and at this time, the slave machine 4 starts to execute the corresponding function according to the received second power supply instruction.
For example, if the second operation instruction is an operation instruction for providing a heat function, a second power supply instruction with a dc value of 300V is generated according to the second operation instruction, and then the second operation instruction is forwarded to the slave 4 through the master 2, so as to start the slave 4 to perform the heat function, and at the same time, the master 2 supplies power to the slave 4, specifically, the second operation instruction is forwarded to the slave 4 and outputs a dc value of 300V.
In a specific embodiment, the step S120 of generating a first operation instruction and a second operation instruction corresponding to the first required function information and the second required function information respectively includes the steps of:
and screening out a first operation instruction corresponding to the first required function information according to a preset function configuration table.
Specifically, the function configuration table may include operation instructions corresponding to different required function information, the different required function information may include different execution functions, and the operation instruction matching with the current required function information may be screened from the function configuration table. If the first requirement function information is a function requirement for providing cooling capacity, a first operation instruction corresponding to the first requirement function information is generated from a plurality of execution functions contained in a function configuration table. For example, the function configuration table includes operation instructions respectively corresponding to functions of providing cooling capacity, heating capacity, dehumidifying, and blowing, and when the first demand function information transmitted from the host 2 is received, specifically, when the usage demand for providing cooling capacity indoors is received, the first operation instruction corresponding to the usage demand for providing cooling capacity included in the function configuration table is selected.
And screening out a second operation instruction corresponding to the second required function information according to the function configuration table.
Specifically, the operation instruction matched with the current second requirement function information is also screened from the function configuration table. And if the second required function information is the function requirement for providing heat, generating a second operation instruction corresponding to the second required function information from a plurality of execution functions contained in the function configuration table. For example, when the second required function information transmitted from the host 2 is specifically a use requirement for providing heat to the room, the second required function information is selected from the operation instruction for providing heat included in the function configuration table, so as to generate a second operation instruction corresponding to the use requirement for providing heat.
If the first requirement function information and the second requirement function information of the embodiment are both the function requirements for providing the cooling capacity during use, the first requirement function information and the second requirement function information are both selected from the operation instructions for providing the cooling capacity, which are contained in the function configuration table, and a first operation instruction and a second operation instruction which respectively correspond to the use requirements for providing the cooling capacity are generated.
In a specific embodiment, the step S130 of generating a first power supply instruction and a second power supply instruction corresponding to the first operation instruction and the second operation instruction respectively includes the steps of:
and screening out a first direct current value and a second direct current value respectively corresponding to the first operation instruction and the second operation instruction according to a preset direct current value configuration table.
Specifically, the dc power configuration table of the present embodiment may include power supply instructions corresponding to different operation instructions, and the different operation instructions include different dc power values, so that a dc power value matching the current operation instruction needs to be screened from the dc power configuration table. If the first operation instruction determines one of the various functional requirements, a first direct current value corresponding to the first operation instruction is generated from a plurality of direct current values contained in a direct current value configuration table. For example, the dc electrical value configuration table includes different high-voltage dc electrical values and different low-voltage dc electrical values, a 400V high-voltage dc electrical value and a 50V low-voltage dc electrical value corresponding to the first operation instruction are screened out from the dc electrical value configuration table, and then a corresponding first power supply instruction is generated according to the first dc electrical value.
And when the other second operation instruction is determined to provide one of the various functional requirements, generating a second direct current value corresponding to the second operation instruction from a plurality of direct current values contained in the direct current value configuration table, screening a 400V high-voltage direct current value and a 50V low-voltage direct current value corresponding to the second operation instruction from the direct current value configuration table, and then generating a corresponding second power supply instruction according to the second direct current value.
In addition, in this embodiment, when the high-voltage dc value and the low-voltage dc value are selected, the high-voltage dc value of 400V and the low-voltage dc value of 50V are not limited, the high-voltage dc value may be limited within a range of 200 to 500V, and the low-voltage dc value may be limited within a range of 20 to 60V.
In a specific embodiment, the host 2 specifically includes a host indoor unit and a host outdoor unit, the host indoor unit is installed in an indoor environment, the host outdoor unit is installed in an outdoor environment, the host outdoor unit establishes signal transmission connection and circuit transmission connection with the variable current controller 3, and the variable current controller 3 inputs various commands and electric quantity into the host outdoor unit; the host outdoor unit and the host indoor unit establish signal transmission connection and circuit transmission connection, and the variable flow controller 3 inputs various instructions and electric quantity into the host indoor unit through the host outdoor unit. The first power supply instruction comprises a first power supply gear and a second power supply gear. Step S140, transmitting the first power supply instruction to the host 2, and outputting a dc power value corresponding to the first power supply instruction, includes the steps of:
and generating a first power supply gear and a second power supply gear respectively corresponding to the host outdoor unit and the host indoor unit according to the first power supply instruction.
Specifically, the first power supply instruction is transmitted by the host outdoor unit and the host indoor unit correspondingly, and the power supply power generally required by the host outdoor unit is higher in requirement, so that a high-voltage direct-current electric value, namely a high-voltage direct-current electric value in the range of 200-500V, needs to be selected from the high-voltage direct-current electric value and the low-voltage direct-current electric value, and the corresponding first power supply gear is generated by the high-voltage direct-current electric value. For example, if the first power supply command requires a high-voltage direct current electric value of 400V, a first power supply gear corresponding to the high-voltage direct current electric value of 400V is generated.
In addition, the power supply power requirement generally required by the main indoor unit is lower than that of the main outdoor unit, so a low-voltage direct-current value, that is, a low-voltage direct-current value within a range of 20 to 60V, needs to be selected from the high-voltage direct-current value and the low-voltage direct-current value, and the corresponding second power supply gear is generated according to the low-voltage direct-current value. For example, if the first power supply command requires a low-voltage dc power value of 50V, a second power supply range corresponding to the low-voltage dc power value of 50V is generated.
And transmitting the first power supply gear to the host outdoor unit, and outputting a direct current value corresponding to the first power supply gear to the host outdoor unit.
Specifically, since the first power supply gear is the first power supply gear of the high-voltage direct-current electric value, after the first power supply gear is transmitted to the host outdoor unit, power can be supplied to the host outdoor unit at that time, and the direct-current electric value corresponding to the first power supply gear is output. For example, the first power supply gear is a high-voltage direct-current power value of 400V, and after the first power supply gear is transmitted to the main unit outdoor unit, the 400V direct current can be output to the main unit outdoor unit.
And forwarding the second power supply gear to the host indoor unit through the host outdoor unit, and outputting a direct current value corresponding to the second power supply gear to the host indoor unit.
Specifically, since the second power supply gear is the low-voltage dc value, after the second power supply gear is transmitted to the host outdoor unit, power can be supplied to the host indoor unit at that time, and the dc value corresponding to the second power supply gear is output. For example, the second power supply gear with a low voltage dc value of 50V is forwarded to the host indoor unit through the host outdoor unit, and then the 50V dc power can be output to the host indoor unit.
In a specific embodiment, the slave 4 comprises a slave indoor unit and a slave outdoor unit, the slave indoor unit is installed in an indoor environment, the slave outdoor unit is installed in an outdoor environment, the slave outdoor unit and the master outdoor unit establish signal transmission connection and circuit transmission connection, and various commands and electric quantity are input into the slave outdoor unit through the master outdoor unit by the variable current controller 3; the slave outdoor unit and the slave indoor unit establish signal transmission connection and circuit transmission connection, and the variable flow controller 3 inputs various instructions and electric quantity from the slave indoor unit through the master outdoor unit and the slave outdoor unit; the second power supply instruction comprises a third power supply gear and a fourth power supply gear. Step S150, forwarding the second power supply instruction to the slave 4 through the master 2, and outputting a dc value corresponding to the second power supply instruction, includes the steps of:
and generating a third power supply gear and a fourth power supply gear respectively corresponding to the slave outdoor unit and the slave indoor unit according to the second power supply instruction.
Specifically, the second power supply instruction is transmitted by the slave outdoor unit and the slave indoor unit, and the power supply power generally required by the slave outdoor unit is higher in requirement, so that a high-voltage direct-current electric value, that is, a high-voltage direct-current electric value in the range of 200 to 500V needs to be selected from the high-voltage direct-current electric value and the low-voltage direct-current electric value, and the corresponding third power supply gear is generated by using the high-voltage direct-current electric value. For example, if the second power supply command requires a high-voltage direct-current electric value of 400V, a third power supply gear corresponding to the high-voltage direct-current electric value of 400V is generated.
In addition, the power supply power requirement generally required by the slave indoor unit is lower than that of the slave outdoor unit, so that a low-voltage direct-current value, that is, a low-voltage direct-current value in the range of 20 to 60V needs to be selected from the high-voltage direct-current value and the low-voltage direct-current value, and the corresponding fourth power supply gear is generated according to the low-voltage direct-current value. For example, if the second power supply command requires a low-voltage dc power value of 50V, a fourth power supply range corresponding to the low-voltage dc power value of 50V is generated.
And forwarding the third power supply gear to the slave outdoor unit through the master outdoor unit, and outputting a direct current value corresponding to the third power supply gear to the slave outdoor unit.
Specifically, since the slave outdoor unit cannot independently supply power, the master outdoor unit is required to forward the direct current to the slave outdoor unit before operation. For example, a third power supply gear with a high-voltage direct-current electric value of 400V is transmitted to the slave outdoor unit through the master outdoor unit, so that 400V direct current can be output to the slave outdoor unit.
And forwarding the fourth power supply gear to the slave indoor unit through the master outdoor unit and the slave outdoor unit, and outputting a direct current value corresponding to the fourth power supply gear to the slave indoor unit.
Specifically, the slave indoor units are also not independently powered, and therefore, the slave indoor units are required to forward the direct current to the slave outdoor units through the master outdoor unit, and then to forward the direct current to the slave indoor units through the slave outdoor units. For example, a fourth power supply shift with a low voltage dc value of 50V is transmitted to the slave outdoor unit through the master outdoor unit and the slave outdoor unit, so that 50V dc power can be output to the slave outdoor unit.
The host outdoor unit of this embodiment includes host outdoor unit controller, compressor, outdoor fan, heat exchanger and coupling assembling. The host indoor unit comprises a host indoor unit controller, an indoor fan, a heat exchanger and a connecting assembly. The host outdoor unit controller and the host indoor unit controller establish signal transmission connection and circuit transmission connection.
The slave outdoor unit of the embodiment comprises a slave outdoor unit controller, a compressor, an outdoor fan, a heat exchanger and a connecting assembly. The slave indoor unit comprises a slave indoor unit controller, an indoor fan, a heat exchanger and a connecting assembly. The master outdoor unit controller and the slave outdoor unit controller establish signal transmission connection and circuit transmission connection, and the slave outdoor unit controller and the slave indoor unit controller establish signal transmission connection and circuit transmission connection.
