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.
Referring to fig. 1, the present embodiment provides a method for controlling starting of a compressor, which can solve the problems of unstable voltage and power supply trip caused by simultaneous starting of compressors corresponding to a plurality of indoor units.
It should be noted that the compressor start control method provided in this embodiment can be applied to an air conditioner with a power-down memory function, that is, when the air conditioner is powered on again after a power-down, the compressors corresponding to a plurality of indoor units can be started in a staggered manner by the compressor start control method, so as to avoid the problem that a power supply is tripped due to unstable voltage caused by simultaneous start of a plurality of compressors. In addition, the compressor start control method provided in this embodiment is also applicable to the self-starting of other compressors, for example, when the air conditioner receives an instruction, the instruction controls the start of the plurality of compressors, where the instruction may be issued by an operator, for example, the operator starts the plurality of compressors through a master switch of the air conditioner; or the instruction can be sent out by a computer or other general control units.
The compressor starting control method comprises the following steps:
and step S1, receiving inner ring temperature data of a plurality of indoor units.
Note that the inner-loop temperature data of the indoor units indicates the internal ambient temperatures of the plurality of indoor units. The indoor units are installed at different positions, so that the internal environment temperatures of the indoor units are different. In the present embodiment, for the detection of the inner ring temperature data of each indoor unit, the inner ring temperature of each indoor unit is detected by using an independent temperature sensor for each indoor unit. Therefore, even if two indoor units are located in the same closed space, the inner ring temperature data detected by two different temperature sensors are different.
And step S2, controlling the compressors of the indoor units corresponding to each other one by one to start in sequence according to the inner ring temperature data.
The compressors of the indoor units are respectively controlled to be sequentially started through the inner ring temperatures of the indoor units, so that the starting time of the compressors can be staggered, the compressors are prevented from being started simultaneously, and the problem that the current is suddenly increased due to the simultaneous starting of the compressors corresponding to the indoor units, the voltage is unstable, and even the power supply is tripped is solved. And then can guarantee the compressor that the indoor set corresponds and start steadily, avoid unstable voltage to cause the damage to the compressor simultaneously.
It should be noted that the sequential starting of the compressors refers to a manner that the plurality of compressors can be started sequentially, or two of the plurality of compressors can be started sequentially. The multiple compressors can be started at different times, and the problem that the current suddenly increases due to the simultaneous starting of the compressors corresponding to the indoor units, so that the voltage is unstable and even the power supply is tripped is solved.
Further, referring to fig. 2, step S2 includes:
and step S21, generating and sending a first time delay command for controlling the corresponding compressors to be sequentially started according to the integer part of the numerical value of the inner ring temperature data.
It should be noted that the delay duration of the first delay command includes a sum of the duration of the delay base and the duration of the adjustment delay. That is, the first delay command includes a delay time of the delay base and a delay time of the adjustment delay.
In this embodiment, the plurality of compressors corresponding to the different control according to the difference of the integer part of the inner ring temperature data are started with different delay times, and then the starting times of the plurality of compressors are staggered, so that the problem that the current suddenly increases due to the simultaneous starting of the compressors corresponding to the plurality of indoor units, which causes unstable voltage and even causes power tripping can be solved.
It should be noted that, the difference of the internal ambient temperatures in the indoor units causes the difference of the inner ring temperature data of the indoor units, wherein the difference can be represented as the difference of the integer parts of the inner ring temperature data, and at this time, the sequential start of the compressors staggered with each other can be controlled according to the different integer parts.
Referring to fig. 2 and fig. 3, step S21 includes:
and S211, if the integer part of the numerical value of the inner ring temperature data is an odd number, generating and sending a first delay command for controlling the corresponding compressor to delay the start of the first delay time after the indoor unit is powered on.
The indoor unit with the integer part of the inner ring temperature data as the odd number is controlled to be started after being electrified and delayed for the first delay time, the part with the integer part as the odd number and other parts can be separated to start the compressor, and therefore the starting time of the compressor is staggered.
Further, in this embodiment, the delay base includes a first delay base, the adjusted delay includes a first adjusted delay, and the first delay time includes the first delay base and the first adjusted delay. And, wherein the first adjusted delay is an even number. That is, when the integer part of the inner ring temperature data is judged to be an odd number, the delay time length of the first delay command matched with the corresponding compressor at the moment is the sum of the time length of the first delay base number and the time length of the first adjustment delay.
Further, step S21 includes:
and S212, if the integer part of the numerical value of the inner ring temperature data is an even number, generating and sending a first delay command for controlling the corresponding compressor to delay the start of the second delay time after the indoor unit is powered on.
The indoor unit with the integer part of the inner ring temperature data as the even number is controlled to be started after the power-on delay time of the indoor unit, the part with the integer part as the even number and other parts can be separated to start the compressor, and therefore the starting time of the compressor is staggered.
Further, in this embodiment, the delay base further includes a second delay base, the adjusting the delay further includes a second adjusting delay, and the second delay time includes the second delay base and the second adjusting delay. And wherein the second adjusted delay is an even number. That is, when the integer part of the inner ring temperature data is judged to be an even number, the delay time length of the first delay command matched with the corresponding compressor at the moment is the sum of the time length of the second delay base number and the time length of the second adjustment delay.
It should be noted that, in this embodiment, the plurality of compressors corresponding to different inner ring temperature data are sequentially started by dividing the compressors into two parts according to the odd-even property of the integer part. To stagger the start-up times of the multiple compressors. It should be understood that in other embodiments, the start-up times of the compressors corresponding to the inner ring temperature data may be divided in other manners, for example, a value of the unit number of the integral part of the inner ring temperature data is divided into two parts by taking 5 as a node, the unit number is greater than or equal to 5, and the first delay command is used for allocating the first delay time of the compressor, and the unit number is less than 5, and the second delay command is used for allocating the second delay time of the compressor.
In addition, the starting time of the plurality of compressors can be staggered by distributing a first delay command of a first delay time to the compressors corresponding to the inner ring temperature data with the odd integer part and distributing a first delay command of a second delay time to the compressors corresponding to the inner ring temperature data with the even integer part so as to divide the plurality of compressors into at least two batches for starting.
In this embodiment, the first delay base number and the second delay base number are equal, specifically, the first delay base number is three minutes, and the second delay base number is three minutes. It should be appreciated that the first delay base and the second delay base may be manually set to other time periods in other embodiments, such as 5 minutes, 4 minutes, or 2 minutes, for example. Also, the first delay base and the second delay base may be different.
In addition, in this embodiment, the first adjustment delay is even, and the second adjustment delay is odd, so that the delay command of the first delay time is different from the delay command of the second delay time when the first delay base is the same, and it is ensured that the plurality of compressors can be started in a plurality of batches. It should be understood that in other embodiments, the first adjustment delay and the second adjustment delay may be set differently, for example, the first adjustment delay is 0-30 seconds, the second adjustment delay is 31-60 seconds, etc.
Further, referring to fig. 2 and fig. 4 in combination, in the present embodiment, after step S21, the method for controlling the start of the compressor further includes:
and step S22, generating and sending a second delay command for controlling the corresponding compressors to start in sequence according to the first delay command and the decimal part of the numerical value of the inner ring temperature data.
The delayed starting commands for the compressors are adjusted according to the decimal part of the numerical value of the inner ring temperature data to control the compressors to be started in sequence, and then a plurality of compressors corresponding to a plurality of indoor units can be further staggered into a plurality of delayed starting times, so that the staggered starting of the compressors is further ensured, and the problems that the current is suddenly increased due to the simultaneous starting of the compressors corresponding to the indoor units, the voltage is unstable, and even the power supply is tripped are solved. And then can guarantee the compressor that the indoor set corresponds and start steadily, avoid unstable voltage to cause the damage to the compressor simultaneously.
That is, after the inner ring temperature data is divided into two parts according to the odd-even property of the integer part through step S21, the plurality of compressors with the integer part being an odd number or the plurality of compressors with the integer part being an even number are further divided into a plurality of batches to be started according to the fractional part of the inner ring temperature data, so that the number of the compressors to be started at the same time can be further reduced, and the problem that the current suddenly increases due to the simultaneous starting of the compressors corresponding to the indoor units, which causes unstable voltage, and even causes power supply tripping can be better solved.
Further, in the present embodiment, step S22 includes:
and step S221, generating and sending a second delay command for controlling the corresponding compressors to be sequentially started according to the first delay command and the first numerical value of the decimal part of the numerical value of the inner ring temperature data.
The compressors are controlled to be sequentially started according to the size of the decimal part of the inner ring temperature data, so that the compressors corresponding to the inner ring temperature data can generate a plurality of second delay commands with different delay lengths according to the decimal part of the inner ring temperature data, the compressors can be started after different delay time, and sequential starting of the compressors in a staggered mode is achieved.
It should be noted that, in this embodiment, the second delay command may be regarded as a delayed compressor start control command formed after the adjusted delay time duration in the first delay command is correspondingly allocated according to the size of the first bit value of the fractional portion of the inner ring temperature data.
Further, in this embodiment, the delay time duration of the second delay command is the sum of the delay base number and the time duration of the adjustment delay correspondingly allocated according to the size of the first digit value of the fractional part of the inner ring temperature data, specifically, the time durations of the adjustment delays sequentially increase from 0 to 9, which correspond to the first digit value of the fractional part of the numerical value of the inner ring temperature data sequentially. That is, when the first numerical value of the decimal part of the inner ring temperature data is sequentially increased, the time length of the corresponding adjustment delay is sequentially increased.
Specifically, in the present embodiment, when the integer part of the inner ring temperature data is an odd number, the first adjustment delays corresponding to the first digit values of the decimal part of the inner ring temperature data from 0 to 9 are 2 seconds, 4 seconds, 6 seconds … … 18 seconds, and 20 seconds in this order. When the integer part of the inner ring temperature data is an even number, the second adjustment delays corresponding to the first digit values of the decimal part of the inner ring temperature data in order from 0 to 9 are 1 second, 3 seconds, 5 seconds … … 17 seconds, and 19 seconds in order. It should be understood that in other embodiments, the first adjustment delay and the second adjustment delay may be distributed differently according to the first bit value of the fractional part of the inner ring temperature data, for example, when the integer part of the inner ring temperature data is odd, the first adjustment delays corresponding to the first bit values of the fractional part of the inner ring temperature data from 0 to 9 are 1 second, 2 seconds, 3 seconds … … 9 seconds, 10 seconds in sequence; when the integer part of the inner-loop temperature data is an even number, the second adjustment delays corresponding to the first digit values of the decimal part of the inner-loop temperature data from 0 to 9 are 11 seconds, 12 seconds, 13 seconds … … 19 seconds, 20 seconds, and the like in sequence.
In addition, in this embodiment, the first delay command is an intermediate transition command, that is, a second delay command is generated according to the first delay command and the fractional part of the inner ring temperature data, and the delayed start control is performed on the plurality of compressors according to the second delay command corresponding to each compressor. It should be appreciated that in other embodiments, the first delay command may be a control command that ultimately issues and controls the start of the compressors, i.e., the plurality of compressors may be directly controlled to start in sequence by the first delay command formed according to the integer portion of the inner loop temperature data.
In summary, referring to fig. 5, in the embodiment, the compressors are divided into two batches according to the odd-even property of the integer part of the inner ring temperature data, and the two batches in which the integer part is the odd number and the integer part is the even number are divided into a plurality of batches according to the size of the first bit value of the fractional part of the inner ring temperature data, and the delay commands with different delay durations are distributed, so that the plurality of compressors can be sequentially started, and the problem that the current suddenly increases due to the simultaneous starting of the compressors corresponding to the plurality of indoor units, which causes unstable voltage, and even causes power supply tripping is solved. And then can guarantee the compressor that the indoor set corresponds and start steadily, avoid unstable voltage to cause the damage to the compressor simultaneously.

The receiving module is used for receiving inner ring temperature data of the indoor units. And the control module is used for controlling the compressors of the corresponding indoor units to be sequentially started according to the inner ring temperature data.
