Wherein, wind turbine wind shelves can be setting wind shelves, can also be any wind shelves in addition to most low wind file；Compressor frequency Rate can be highest frequency, can also be any frequency in addition to low-limit frequency.
Such as：Increase wind shelves (such as：Interior machine wind shelves), frequency (such as：Compressor operating frequency) control.
Such as：Optimization wind shelves automatically control, and are adjusted in conjunction with compressor frequency (i.e. compressor operating frequency).
Such as：It is all identical in other conditions during the control of convertible frequency air-conditioner in a chiller mode (heating is opposite) Under conditions of, air quantity is bigger (alternatively, rotation speed of fan is higher when heating mode) when refrigeration mode, then refrigeration when refrigeration mode (or Person, when heating mode, heat) amount is bigger；Other conditions all under the same conditions, compressor operating frequency is got over when refrigeration mode High (alternatively, rotation speed of fan is higher when heating mode), then (alternatively, being heated when heating mode) amount of freezing when refrigeration mode are bigger.
As a result, by the control to wind turbine wind shelves and compressor frequency, be conducive to the reliability and energy saving that promote control, And promote the comfort that user uses.
In an optional embodiment, in the step s 120, to the pressure of the wind turbine wind shelves and the air-conditioning of the air-conditioning Contracting unit frequency is controlled, and may include：In refrigeration mode, first the compressor frequency is reduced by shelves, again by shelves reduction institute State the downshift control of formula step by step of wind turbine wind shelves.By in refrigeration mode to compressor frequency and wind turbine wind shelves in turn step by step Downshift processing, on the one hand can promote the comfort that user uses, on the other hand can promote energy-saving effect.
With reference in method of the invention shown in Fig. 2 step by step formula downshift control process an embodiment flow chart, into One step illustrates the detailed process of the downshift control of formula step by step of step S120.
Optionally, step S120 formula step by step downshift control detailed process, may include：To the compressor frequency into The process that row downshifts step by step, reference can be made to the concrete operations of step S210- steps S220.
The compressor frequency is reduced by one grade of operation by step S210, and after one grade of compressor frequency of determining reduction Current Temperatures and the set temperature the second difference and determine that the error of first difference and second difference is No is more than preset second temperature threshold value.
In one example, when the compressor frequency is highest frequency, the highest frequency, which is reduced by one grade, to be run, and Described in second difference of the Current Temperatures and the set temperature after determination one grade of highest frequency of reduction and determination Whether the error of the first difference and second difference is more than preset second temperature threshold value.
Step S220 reduces by one grade of compressor frequency when the error is more than the second temperature threshold value by described Compressor frequency after rate reduces by one grade again.
In one example, when the compressor frequency be highest frequency, when the error be more than the second temperature threshold When value, the compressor frequency after one grade of highest frequency of the reduction is reduced by one grade again.
Such as：When refrigeration mode, if △ Tc≤ the first temperature threshold TA, then compressor operating frequency first reduce by one grade of fortune Row a period of time, then compare the difference △ T of inside environment temperature and set temperaturei(i=2,3,4 ...), and compare △ Tc、△Ti, If △ Tc-△Ti> second temperature threshold values TB, then compressor operating frequency reduce by one grade again, so recycle.
As a result, by the downshift step by step to the compressor frequency, can preferentially be adjusted by adjusting compressor frequency Temperature, good energy-conserving effect.
Optionally, step S120 formula step by step downshift control detailed process, can also include：To the wind turbine wind shelves into The process that row downshifts step by step, reference can be made to the concrete operations of step S230.
Step S230, so cycle (i.e. as the downshift mode of step S210 to step S220 recycles), until working as the pressure When contracting unit frequency has been lowered to the low-limit frequency in predeterminated frequency range, if corresponding error is still above the second temperature threshold value When, the wind turbine wind shelves are reduced by one grade.
Such as：So cycle, when the wind turbine wind shelves are setting wind shelves, when the compressor frequency have been lowered to it is described When low-limit frequency in predeterminated frequency range, if the error of first difference and i+1 difference after time reduction still above When the second temperature threshold value, the setting wind shelves are reduced by one grade, and are determined current after reducing by one grade of setting wind shelves Second difference of temperature and the set temperature and determine first difference and second difference error whether be more than The second temperature threshold value；I is the natural number more than 1, indicates to reduce the highest frequency one grade of number.
In turn, when the error is more than the second temperature threshold value, after one grade of setting wind shelves of the reduction The wind shelves of the interior machine reduce by one grade again.
Such as：When refrigeration mode, when running frequency has fallen to the minimum operating frequency of setting, still there are △ Tc-△Ti> TBWhen, inner blower operation wind shelves start to reduce by one grade automatically, detect still according to above-mentioned condition, so recycle.
As a result, by further being dropped step by step to the setting wind shelves when compressor frequency temperature adjustment is not up to demand Shelves, while ensureing energy-saving effect, further to promote the comfort that user uses.
Optionally, step S120 formula step by step downshift control detailed process, can also include：Stop compressing when up to temperature spot The process of machine, reference can be made to the concrete operations of step S240.
Step S240, so cycle (i.e. as the downshift mode of step S240 recycles), until the wind turbine wind shelves are reduced to When preset most low wind file, if corresponding error is still above the second temperature threshold value, stop the compressor, and makes described Wind turbine is run by the lowest gear.
In one example, such cycle, until the wind turbine wind shelves are when being reduced to preset most low wind file, if described the When the error of one difference and the m+1 differences after secondary reduction is still above the second temperature threshold value, stop the compressor, and The wind turbine is set to be run by the lowest gear；M is the natural number more than 1, indicates to reduce the setting wind shelves one grade of time Number.
Such as：When refrigeration mode, when wind shelves also have already decreased to the minimum operation wind shelves of design, above-mentioned condition is still full Foot, then stop compressor, and interior machine is run according to currently most low wind file.
Stop compressor when as a result, by when wind turbine wind shelves are reduced to most low wind file under refrigeration mode, carrying out up to temperature spot, it can Under the premise of ensureing comfort that user uses, further to promote energy-saving effect.
In an optional embodiment, in the step s 120, to the pressure of the wind turbine wind shelves and the air-conditioning of the air-conditioning Contracting unit frequency is controlled, and can also include：In heating mode, first reduces by one grade of wind turbine wind shelves, reduces by one grade of institute again State the staggered form downshift control of compressor frequency.By in heating mode to the staggered forms of wind turbine wind shelves and compressor frequency according to It is secondary to downshift step by step, the comfort that user uses on the one hand can be promoted, energy-saving effect on the other hand can be promoted.
The flow chart for the embodiment of control module that downshifts with reference to staggered form in method of the invention shown in Fig. 3, into One step illustrates the detailed process of the staggered form downshift control of step S120.
Optionally, step S120 staggered form downshift control detailed process, may include：To the setting wind shelves and institute The process that highest frequency downshifts successively is stated, reference can be made to the detailed process of step S310- steps S330.
The wind turbine wind shelves are reduced by one grade of operation, and determine working as after reducing by one grade of wind turbine wind shelves by step S310 Whether the second difference and the error of determining second difference and first difference of preceding temperature and the set temperature surpass Cross preset third temperature threshold.
In one example, when wind turbine wind shelves are setting wind shelves, the setting wind shelves are reduced into one grade of operation, and determine Reduce the Current Temperatures after one grade of setting wind shelves and the second difference of the set temperature and determining described second Whether the error of difference and first difference is more than preset third temperature threshold.
Step S320, when the error is more than the third temperature threshold, by one grade of compressor frequency reduction, and It determines the third difference of Current Temperatures and the set temperature after reducing by one grade of compressor frequency and determines described the Whether the error of three differences and first difference is more than the third temperature threshold.
In one example, when compressor frequency is highest frequency, when the error is more than the third temperature threshold When, the highest frequency is reduced by one grade, and determine that the Current Temperatures after reducing by one grade of highest frequency are set with described Whether the error of the third difference of constant temperature degree and the determining third difference and first difference is more than the third temperature Threshold value.
Step S330, when the error is more than the third temperature threshold, after one grade of wind turbine wind shelves of the reduction The wind shelves of the interior machine reduce by one grade again.
In one example, when the error is more than the third temperature threshold, by one grade of setting of the reduction The wind shelves of the interior machine after wind shelves reduce by one grade again.
