Specific embodiment
In the application, the representative equipment of variable volume system is air conditioner, for the ease of being illustrated, following interior Rong Zhong is described in detail by control process of the air conditioner to variable volume system；In described below, air conditioner and it can become Appearance system is considered as equivalent；Those skilled in the art are when understanding the application, it is not possible to merely due to literal difference, and Air conditioner and variable volume system are considered two mutually different restrictions.
In the application, the operational mode of usual air-conditioning includes: refrigeration mode, heating mode, ventilation mode, dehumidification mode etc. Mode.Single cylinder operation mode, twin-tub operation mode, single cylinder increasing enthalpy operation mode, twin-tub increasing enthalpy operation mode are the operation of air-conditioning Mode.
It is explained for the ease of the operation mode to air-conditioning, we are with earlier patent application: a kind of air-conditioning tonifying Qi Increasing enthalpy method, system and air-conditioning (application number: are explained based on 201510416281.3).Wherein, air-conditioning passes through benefit The mode of gas achievees the effect that increasing enthalpy, on this basis, in order to increase the ability to work of compressor, can set compressor to There are two the compressors of compression cylinder (being also possible to multiple) for tool, in this way, being single cylinder in the case where single compression cylinder is only used only Operation mode is twin-tub operation mode using two compression cylinders or multiple compression cylinders, in fact, can also be with On the basis of single cylinder operation mode and twin-tub operation mode, increase multiple operation modes, to correspond to using multiple compression cylinders Situation.
Single compression cylinder is only used only in single cylinder operation mode therein as a result, as compressor, and does not carry out to air conditioner Increasing enthalpy；Twin-tub operation mode, as compressor use two or more compression cylinders, but do not carry out increasing enthalpy to air conditioner；Single cylinder increases Single compression cylinder is only used only in enthalpy operation mode, as compressor, but carries out increasing enthalpy to air conditioner；Twin-tub increasing enthalpy operates mould Formula, as compressor use two or more compression cylinders, and carry out increasing enthalpy to air conditioner.
In order to realize the more accurate control to compressor, it is necessary to first be carried out to the variation of the working condition of compressor clear The understanding of Chu.In normal working condition, compressor can adjust the running frequency of itself according to the actual demand of air conditioner (being the actual motion frequency that external controller controls compressor by control signal during actual adjustment), if air-conditioning The refrigerating capacity or heating capacity that device needs are higher, and compressor can improve the running frequency of itself, to meet the needs of air conditioner；If The refrigerating capacity or heating capacity that air conditioner needs are lower, and compressor can reduce itself in the case where meeting the needs of air conditioner Running frequency.
On this basis, we are further illustrated the transfiguration of compressor.In order to make it easy to understand, we are by way of example The mode of son is illustrated situation.It is emphasized that.Specific number in the example shown, merely to show size relation, The not exact value of actual working state.It is exemplified below:
Under the normal operation of air conditioner, compressor is run with a certain running frequency, can achieve 3500 watts of system Cooling capacity.At this point, user has adjusted the target temperature of room temperature there may be a kind of situation, to reach the target temperature, need The running frequency of compressor is wanted to be adjusted, to reach 7000 watts of refrigerating capacity；In the case, in order to reach the system of air conditioner Cold requirement needs to carry out transfiguration to compressor.
It is of course also possible to there is another situation, if outdoor environment produces lasting high temperature, so that the refrigeration of air conditioner Effect produces decaying, that is to say, compressor is run with the running frequency, is unable to reach 3500 watts of refrigerating capacity.Herein In the case of, in order to reach the refrigeration requirement of air conditioner, need to carry out transfiguration increasing enthalpy to compressor.
To make the above purposes, features and advantages of the invention more obvious and understandable, with reference to the accompanying drawing to the present invention Specific embodiment be described in detail.
As shown in Figure 1, its flow chart for the control method of the air condition of that present invention；Wherein, the controlling party of the air conditioner Method, comprising:
Step 300, the operating parameter of air conditioner is obtained；
Wherein, the operating parameter includes the first parameter and the second parameter, and first parameter is that the target of compressor is transported Line frequency, second parameter are delivery temperature, evaporating temperature or suction temperature.
Wherein, the running frequency of compressor can be measured directly by the electric controller in air conditioner, measure compression The running frequency of machine.Measurement is simple, convenient, is convenient for judging.
On this basis, using the target operating frequency of compressor as the first parameter, can than running frequency judgement more It is accurate.Main reason is that in the control of air conditioner, for the ease of carrying out quick refrigerating/heating, the operation of compressor Frequency can generally be run according to the target operating frequency of setting, the control section in air conditioner, by changing object run Frequency influences come the actual motion frequency on compressor.
Wherein, the delivery temperature is the temperature of exhaust outlet of compressor.The suction temperature is compressor air suction mouth Temperature.The evaporating temperature is the temperature of evaporator in air conditioner.Wherein, in order to make it easy to understand, in the application, evaporator is It is played in air conditioner by the device of cryogenic condensation liquid gasification, is absorbed heat, in air conditioner refrigeration, evaporator is located at air conditioning chamber In interior machine, in air conditioner heat-production, evaporator is located in air-conditioner outdoor unit；It wherein, can be by evaporator for the ease of measurement Temperature of the coil temperature as evaporator.
Similarly, in order to make it easy to understand, in the application, condenser is to be played in air conditioner by high-temperature gas or steam condensation For the device of liquid, heat release is carried out, in air conditioner refrigeration, evaporator is located in air-conditioner outdoor unit, in air conditioner heat-production, steams Hair device is located in air conditioner indoor unit；It wherein, can be using the coil temperature of condenser as the temperature of condenser for the ease of measurement Degree, as condensation temperature.
Wherein, target operating frequency and delivery temperature, are positively correlated；It that is to say, target operating frequency can be with exhaust temperature The increase of degree and increase, reduce with the reduction of delivery temperature.Target operating frequency and evaporating temperature, suction temperature are in negative It closes；It that is to say, running frequency can reduce with the increase of evaporating temperature or suction temperature.With evaporating temperature or air-breathing temperature The reduction of degree and increase.
Optionally, after air conditioner powers on, compressor and other elements on startup, fluctuation of service, in the case Operating parameter, the real-world operation situation of air conditioner can not be reacted, therefore after power-on of air conditioner, step 300, obtain air conditioner Operating parameter before, can also allow air conditioner operation a period of time, in this way, the operating parameter of air conditioner can be made to tend to be steady It is fixed, to avoid the situation for judging inaccuracy caused by fluctuation of service.
Step 400, judge whether the operating parameter meets the first preset condition；
Since target operating frequency and delivery temperature are positively correlated, and target operating frequency and evaporating temperature or air-breathing temperature It spends negatively correlated.Therefore, when judging whether first parameter and second parameter meet the first preset condition, described It is the judgement in the case where evaporating temperature or suction temperature with second parameter in the case that second parameter is delivery temperature Standard will be different.
It is pre- to whether first parameter and second parameter meet first in order to use same or similar standard If condition is judged；In the present embodiment, it needs to be adjusted evaporating temperature and suction temperature, so that adjusted Evaporating temperature or suction temperature, are positively correlated with target operating frequency.For the ease of being adjusted, condensation temperature is incorporated herein Degree；The condensation temperature, is the temperature of condenser in air conditioner, and the condensation temperature is positively correlated with target operating frequency.Institute That states is adjusted, and is exactly by condensation temperature divided by evaporating temperature, or by condensation temperature divided by suction temperature.In this way, working as institute State the second parameter be evaporating temperature perhaps suction temperature when by the ratio or condensation temperature of condensation temperature and evaporating temperature and suction The ratio of temperature degree, as judging whether second parameter meets the foundation of the first preset condition.
Judge in this way, so that it is more accurate to the judgement of the practical operation situation of air conditioner, consequently facilitating being obtained by judgement Take the opportunity of more accurate operation mode switching.
Wherein, if operating parameter includes the first parameter and the second parameter, meet the first preset condition in this step, refer to First parameter and the second parameter meet first preset condition simultaneously；If operating parameter further includes third parameter or more ginseng Number then in this step, meets the first preset condition, refers to the first parameter, the second parameter, third parameter or more, simultaneously Meet first preset condition.In addition, it should be noted that the second parameter be delivery temperature, evaporating temperature or suction temperature, In other words, the second parameter meets preset condition, and essence is meant that any in delivery temperature, evaporating temperature or suction temperature One meets preset condition.
Step 500, if satisfied, then switching or remaining twin-tub operation mode for the air conditioner；
If meeting first preset condition, show that the load of air conditioner is higher；If still single cylinder is taken to operate at this time Mode may then be difficult meet the needs of air conditioner, or compressor is needed just to can satisfy with high running frequency operation The demand of air conditioner (runs compressor with high running frequency, very big damage can be not only brought to compressor, but also can produce Raw great noise, influences the normal use of air conditioner).
In the case, the air conditioner is switched to twin-tub operation mode, compressor can be made with suitable operation Frequency just can satisfy the demand of air conditioner when running, play the role of reducing noise and extend compressor service life, thus The experience effect of user can be increased.
Wherein, air conditioner in the process of running, can be general to produce with the variation of external environment or the variation of user's control Raw two kinds of problems: one, need higher refrigerating capacity or heating capacity demand, two, air conditioner attenuated inside.Obtain object run frequency The purpose of rate, exactly be used to speculate in the air conditioner, produce above-mentioned any problem or whether at the same produce two kinds (the case where due to air conditioner in actual operation, is increasingly complex, is also possible to lead to the problem of the third except both the above for problem Kind or the 4th kind of problem, therefore, supposition of the target operating frequency for air conditioner is the conclusion for obtaining a Relative Fuzzy), The characteristic that different problems are shown be it is different, speculated only by target operating frequency, uncertainty is very Height, therefore by itself and delivery temperature in the application, evaporating temperature or suction temperature, which combine, to be judged, can reduce it Uncertainty increases the accuracy of judgement, so that the switching of air conditioner operation mode is more accurate.
Step 600, if not meeting, the air conditioner is switched or is remained single cylinder operation mode.
When not meeting the first preset condition, show that the load of air conditioner is lower, in the case, the air conditioner is switched For single cylinder operation mode, the demand of air conditioner not only can satisfy, but also can reduce the energy consumption of air conditioner, improve the efficiency of air conditioner Than.It should be noted that the step 400, judges whether the operating parameter meets in the first preset condition, which is one The judgement of secondary property that is to say and directly judge whether to meet the first preset condition, meets just with the operation of twin-tub operation mode, is unsatisfactory for Just with the operation of single cylinder operation mode；Can't duration judgement (routinely judge, will lead to deterministic process and constantly recycle, no It is switched to single cylinder operation mode or twin-tub operation mode disconnectedly).
In addition, it is necessary to illustrate, in the application, air conditioner has single cylinder operation mode, twin-tub operation mode, and single cylinder increases Enthalpy operation mode, totally four operation modes in other words after air conditioner powers on, are freezing or are heating twin-tub increasing enthalpy operation mode When, one of aforementioned four operation mode will be switched to.Under normal circumstances, single cylinder behaviour can be directly entered after air conditioner powers on Operation mode, but be not precluded in special circumstances, air conditioner is directly entered other three operation modes (such as according to shutdown after powering on Operation mode before is as the default mode of operation after starting), in the application step 300- step 600, not singly refer to Operating parameter is obtained under the single cylinder operation mode of air conditioner, obtains operating parameter (only in the case of can also be other three kinds When judgement meets the first preset condition, specific threshold parameter be will be different), therefore, if directly being grasped after powering on single cylinder Operation mode operation, then be judged as after being unsatisfactory for the first preset condition, can remain single cylinder operation mode, is judged as that satisfaction first is pre- If after condition, twin-tub operation mode can be switched to；If being directly judged as with the operation of twin-tub operation mode after powering on and being unsatisfactory for the After one preset condition, it can be switched to single cylinder operation mode, be judged as after meeting the first preset condition, twin-tub operation mould can be remained Formula；If directly being run after powering on single cylinder increasing enthalpy mode or twin-tub increasing enthalpy operation mode, it is judged as and is unsatisfactory for the first default item After part, it can be switched to single cylinder operation mode, be judged as after meeting the first preset condition, twin-tub operation mode can be switched to.
Optionally, when meeting any one in following condition, determine that first parameter and second parameter are full Foot first preset condition:
Condition one: the target operating frequency is greater than first frequency threshold value and the delivery temperature is greater than the first temperature threshold Value；
Condition two: the target operating frequency is greater than first frequency threshold value and the condensation temperature and the evaporating temperature Ratio is greater than the first evaporite ratio threshold value；
Condition three: the target operating frequency is greater than first frequency threshold value and the condensation temperature and the suction temperature Ratio is greater than the first aspiration ratio threshold value.
Above three condition respectively corresponds three embodiments, that is to say second parameter be delivery temperature, evaporating temperature, Three kinds of situations of suction temperature；Wherein, condition one it is corresponding be second parameter be delivery temperature embodiment；Condition two is right What is answered is the embodiment that second parameter is evaporating temperature；It is reality that second parameter is suction temperature that condition three is corresponding Apply example.
When being described to the first preset condition the case where, we are by taking delivery temperature as an example (it should be noted that three Corresponding three embodiments of condition have relatively high similarity, in the case where knowing the embodiment of delivery temperature, this field Technical staff also is understood that other two embodiments) it is illustrated.The running frequency is greater than first frequency threshold value, it is meant that The compressor just can satisfy the refrigeration or heating needs of air conditioner with the operation of higher running frequency；The delivery temperature Greater than the first temperature threshold, it is meant that the running environment (internal operating environment of the air conditioner) of the compressor is poor, produces Given birth to decaying or caused by decay it is very big；When in other words meeting the first preset condition, show that the load of air conditioner is higher.
In the case, the air conditioner is switched to twin-tub operation mode, not only can satisfy the demand of air conditioner, but also can It is run to avoid air conditioner with high running frequency, plays Noise Reduction.
Optionally, the value range of the first frequency threshold value is 50~60Hz；Wherein, in entire air conditioner or transfiguration In increasing enthalpy control system, the range of compressor operating frequency is 20~120Hz, and the operation in the frequency range not will lead to compression The instant failure (being out of order in the very short time) of machine, if but compressor keep the upper frequency within the scope of this to run for a long time, The service life for shortening compressor compared with macrolesion can be still brought to compressor.It is used as first frequency threshold value by 50~60 hertz, The switching that the air conditioner carries out single cylinder operation mode and twin-tub operation mode is controlled, 50 can be kept for a long time to avoid compressor ~60 hertz or more of upper frequency, so can to avoid brought to compressor prevented compared with macrolesion shorten compressor use Service life；High running frequency bring noise can also be avoided simultaneously.
Optionally, the value range of first temperature threshold is 50~60 DEG C；Wherein, in entire air conditioner or transfiguration In increasing enthalpy control system, the general allowed band of delivery temperature is 20~120 DEG C.But if higher temperature is kept for a long time, meeting The CPU in air conditioner is seriously affected, the normal operation of controller etc. shortens the service life of electronic device.50~60 DEG C are made For the first temperature threshold, the switching of operation mode is carried out to air conditioner based on this, when can be long to avoid the delivery temperature of compressor Between keep higher temperature, and then the other component of air conditioner can be made to operate normally, prevent high temperature bring service life from becoming It is short.
Optionally, the value range of the first evaporite ratio threshold value is 4.5~5.5.It should be noted that the first evaporite ratio Threshold value is the threshold value value range (other evaporite ratio threshold values are also similar) of condensation temperature and the ratio of evaporating temperature, the value range It is 4.5~5.5, wherein in entire air conditioner or transfiguration increasing enthalpy control system, the ratio of condensation temperature and evaporating temperature Allowed band is 1~10.The ratio of condensation temperature and evaporating temperature is excessively high, it is meant that in the operating condition of entire air conditioner, operation pressure Power is larger, and each operation part-load of air conditioner is higher, if keeping such operating condition for a long time, can not only shorten associated components Service life, and there may be other serious consequences such as components damage, failure.By 4.5~5.5 as first evaporation Than threshold value, the switching of operation mode is carried out to air conditioner based on this, biggish operation can be kept for a long time to press to avoid air conditioner Power reduces the load of each operation component, to not only prevent from shortening the service life of associated components, but also can prevent thus Other consequences such as components damage, failure of generation.
To suction temperature and evaporating temperature, in existing air conditioner, the outlet of evaporator and the air entry of compressor are (the ignoring control valve, the controlled valve etc. that may be wherein arranged) being directly connected to, low-pressure side is belonged to, therefore, is not being considered When temperature change caused by refrigerant flows, suction temperature is equal with evaporating temperature.
Optionally, similar with the first evaporite ratio threshold value, the value range of the first aspiration ratio threshold value is 4.5~ 5.5.It should be noted that the first aspiration ratio threshold value is threshold value value range (other of the ratio of condensation temperature and suction temperature Aspiration ratio threshold value is also similar), which is 4.5~5.5.It is used as the first aspiration ratio threshold value by 4.5~5.5, is based on This carries out the switching of operation mode to air conditioner, and biggish operating pressure can be kept for a long time to avoid air conditioner, reduces each The load of component is run, to not only prevent from shortening the service life of associated components, but also resulting component can be prevented Other consequences such as damage, failure.
Optionally, as shown in Fig. 2, the control method of the air conditioner further include:
Step 100, the operational mode of air conditioner is obtained；
Step 200, judge whether the operational mode is heating mode or refrigeration mode, if it is not, then terminating；If so, Then obtain the operating parameter of the air conditioner.
The operational mode of air-conditioning is divided into four kinds, is refrigeration mode, heating mode, ventilation mode, dehumidification mode.Wherein, Under dehumidification mode, the running frequency of compressor in air conditioner is required very low, compressor only needs single cylinder operation that can meet and want It asks；Under ventilation mode, starting compressor is not needed.In this way, just being needed only under the refrigeration mode of air-conditioning or heating mode The switching of single twin-tub or increasing enthalpy is carried out according to the operating parameter of air conditioner.
In this way, the operational mode by determining air-conditioning, can control in order to the transfiguration to air conditioner.
As Figure 4-Figure 6, it is multiple embodiments of the control method of air conditioner, content therein is carried out in conjunction with Fig. 3 It illustrates, as follows:
Optionally, after the step 500, the control method of the air conditioner further include:
Step 800, judge whether second parameter meets the second preset condition；
It herein, is that the air conditioner is switched to twin-tub operation mould for whether meeting the judgement of the second preset condition It is carried out after formula.Second parameter meets second preset condition, shows that the load of air conditioner is very high, only twin-tub is taken to operate Mode needs compressor just to can satisfy the demand of air conditioner with high running frequency；In addition it also shows inside air conditioner There may be decaying, further reduced the refrigerating capacity or heating capacity of air conditioner.
Step 900, if meeting second preset condition, the air conditioner is switched to twin-tub increasing enthalpy operation mode；
In the case where meeting second preset condition, the air conditioner is switched to twin-tub increasing enthalpy operation mode, is led to Increasing enthalpy is crossed, the decaying generated inside air conditioner can be reduced, to reduce air conditioner internal environment from another point of view to compressor Compression effectiveness influence, and then increase air conditioner refrigerating capacity or heating capacity；Compressor is also avoided with high fortune Line frequency operation, plays Noise Reduction.
Step 1000, judge whether second parameter meets the 4th preset condition；
It herein, is that the air conditioner is switched to twin-tub increasing enthalpy behaviour for whether meeting the judgement of the 4th preset condition It is carried out after operation mode.Second parameter meets the 4th preset condition, shows the load reduction of air conditioner, only takes double Cylinder increasing enthalpy operation mode, compressor can meet the needs of air conditioner with lower running frequency；In addition air-conditioning is also shown Decaying inside device is also reduced or is disappeared, and the refrigerating capacity or heating capacity of air conditioner have been higher than normal demand.
If meeting the 4th preset condition, the air conditioner is switched to twin-tub operation mode (return step 500).
In this way, by the way that the air conditioner is switched to twin-tub operation mode, the demand of air conditioner not only can satisfy, but also can be with The energy consumption for reducing air conditioner, improves the Energy Efficiency Ratio of air conditioner.
In this way, by the second preset condition of setting and the 4th preset condition, by air conditioner in twin-tub operation mode and twin-tub It is switched between increasing enthalpy operation mode, to not only can satisfy the demand of air conditioner, but also the energy consumption of air conditioner can be reduced, mentioned The Energy Efficiency Ratio of high air conditioner；The decaying generated inside air conditioner can also be reduced simultaneously, avoid compressor with high operation Frequency operation, plays Noise Reduction.
In conclusion passing through the switching of single cylinder and twin-tub, the variation of refrigerating capacity or heating capacity may be implemented；Pass through increasing Enthalpy can reduce the attenuation of air conditioner；In this way, passing through the switching of single cylinder and twin-tub, or by increasing enthalpy, can to press Contracting machine reaches the refrigeration requirement of air conditioner in the case where not changing running frequency.
Optionally, when meeting any one in following condition, it is default to determine that second parameter meets described second Condition:
Condition one: the delivery temperature is greater than second temperature threshold value；
Condition two: the ratio of the condensation temperature and the evaporating temperature is greater than the second evaporite ratio threshold value；
Condition three: the ratio of the condensation temperature and the suction temperature is greater than the second aspiration ratio threshold value.
Above three condition respectively corresponds three embodiments, that is to say second parameter be delivery temperature, condensation temperature, Three kinds of situations of suction temperature；Wherein, condition one it is corresponding be second parameter be delivery temperature embodiment；Condition two is right What is answered is the embodiment that second parameter is evaporating temperature；It is reality that second parameter is suction temperature that condition three is corresponding Apply example.
When being described to the first preset condition the case where, we are by taking delivery temperature as an example (it should be noted that three Corresponding three embodiments of condition have relatively high similarity, in the case where knowing the embodiment of delivery temperature, this field Technical staff also is understood that other two embodiments) it is illustrated.The delivery temperature is greater than second temperature threshold value, it is meant that The running environment (internal operating environment of the air conditioner) of the compressor is poor, there are attenuation or caused by decaying It is more；When in other words meeting the second preset condition, show that the load of air conditioner is higher.
In the case, the air conditioner is switched to twin-tub increasing enthalpy operation mode, by increasing enthalpy, air conditioner can be reduced The decaying that inside generates, to reduce influence of the air conditioner internal environment to the compression effectiveness of compressor from another point of view, in turn Increase the refrigerating capacity or heating capacity of air conditioner；It also avoids compressor to run with high running frequency, plays noise reduction Effect.
Optionally, the value range of the second temperature threshold value is 49~56 DEG C；Wherein, in entire air conditioner or transfiguration In increasing enthalpy control system, the general allowed band of delivery temperature is 20~120 DEG C.But if higher temperature is kept for a long time, meeting The CPU in air conditioner is seriously affected, the normal operation of controller etc. shortens the service life of electronic device.It is envisaged that Since the refrigerating capacity of the same running frequency of compressor under the refrigerating capacity and twin-tub mode of single cylinder mode compression machine differs greatly, so After air conditioner is switched to twin-tub mode, to whether the second temperature threshold value of the switching of increasing enthalpy is also required to be transported according to twin-tub mode Actual demand in row situation is judged.It is used as second temperature threshold value by 49~56 DEG C, air conditioner is operated based on this The switching of mode can not only make to avoid single cylinder and the difference of the refrigerating/heating ability of identical frequency under twin-tub mode is not considered At serious consequence, and higher temperature can be kept for a long time to avoid the delivery temperature of compressor, and then air-conditioning can be made The other component of device operates normally, and prevents high temperature bring service life from shortening.
Optionally, the value range of the second evaporite ratio threshold value is 5.2~6.It is similar to above, switch by air conditioner After twin-tub mode, to whether the second evaporite ratio threshold value of the switching of increasing enthalpy is also required to according to the reality in the case of twin-tub mode operation Border demand is judged.It is used as the second evaporite ratio threshold value by 5.2~6, operation mode is carried out to air conditioner based on this and is cut It changes, it not only can be serious caused by the difference of the refrigerating/heating ability of identical frequency to avoid not considering under single cylinder and twin-tub mode Consequence, and biggish operating pressure can be kept for a long time to avoid air conditioner, reduce the load of each operation component, thus not Only prevent from shortening the service life of associated components, and other consequences such as can prevent resulting components damage, failure.
Optionally, similar with the second evaporite ratio threshold value, the value range of the second aspiration ratio threshold value is 5.2~6. It not only can avoid not considering serious caused by the difference of the refrigerating/heating ability of identical frequency under single cylinder and twin-tub mode Consequence, and biggish operating pressure can be kept for a long time to avoid air conditioner, reduce the load of each operation component, thus not Only prevent from shortening the service life of associated components, and other consequences such as can prevent resulting components damage, failure.
Optionally, when meeting any one in following condition, it is default to determine that second parameter meets the described 4th Condition:
Condition one: the delivery temperature is greater than the 6th temperature threshold and less than the 4th temperature threshold, the 4th temperature threshold Value is less than the second temperature threshold value；
Condition two: the ratio of the condensation temperature and the evaporating temperature is greater than the 6th evaporite ratio threshold value and steams less than the 4th Hair is less than the second evaporite ratio threshold value than threshold value, the 4th evaporite ratio threshold value；
Condition three: the ratio of the condensation temperature and the suction temperature is greater than the 6th aspiration ratio threshold value and inhales less than the 4th Gas is less than the second aspiration ratio threshold value than threshold value, the 4th aspiration ratio threshold value.
Meet that preset condition is similar, and above three condition respectively corresponds three embodiments to above-mentioned determination, we are with exhaust It is illustrated for temperature.The delivery temperature is greater than the 6th temperature threshold and less than the 4th temperature threshold, it is meant that in twin-tub (regardless of whether increasing enthalpy), the running environment (internal operating environment of the air conditioner) of the compressor preferably, will not under mode Cause decaying or caused by decaying it is few；When in other words meeting four preset conditions, show that the load of air conditioner is lower.
In the case, the air conditioner is switched to twin-tub operation mode, not only can satisfy the demand of air conditioner, but also can To reduce the energy consumption of air conditioner, the Energy Efficiency Ratio of air conditioner is improved.
Optionally, the value range of the 6th temperature threshold is 35~42 DEG C.The purpose of the threshold value is set, is in order to true The switching point of order cylinder mode and twin-tub mode herein more than 6th temperature threshold, demonstrates the need for just may be used with twin-tub mode operation Upper frequency is kept for a long time to avoid compressor；The 6th temperature threshold once, shows only to need single cylinder mode herein, so that it may Reach refrigeration demand/heating needs.Simultaneously it is envisaged that due under the refrigerating capacity and twin-tub mode of single cylinder mode compression machine The refrigerating capacity of the same running frequency of compressor differs greatly, so after air conditioner is switched to twin-tub mode, to whether single cylinder The 6th temperature threshold of switching be also required to be judged according to the actual demand in the case of twin-tub mode operation.Based on this to sky Device is adjusted to carry out the switching of operation mode, it not only can be to avoid the refrigerating/heating for not considering identical frequency under single cylinder and twin-tub mode Serious consequence caused by the difference of ability, and higher temperature can be kept for a long time to avoid the delivery temperature of compressor, in turn The other component of air conditioner can be made to operate normally, prevent high temperature bring service life from shortening.
Optionally, the value range of the 6th evaporite ratio threshold value is 3.1~3.9.It is similar to above, it is cut by air conditioner After being changed to twin-tub mode, to whether the 6th evaporite ratio threshold value of the switching of single cylinder or twin-tub is also required to according to twin-tub mode operation feelings Actual demand under condition is judged.It is used as the 6th evaporite ratio threshold value by 3.1~3.9, air conditioner is grasped based on this The switching of operation mode, not only can be to avoid the difference for not considering the refrigerating/heating ability of identical frequency under single cylinder and twin-tub mode Caused by serious consequence, and biggish operating pressure can be kept for a long time to avoid air conditioner, reduce each operation component Load, thus not only prevent from shortening the service life of associated components, but also resulting components damage, failure can be prevented etc. Other consequences.
Optionally, similar with the 6th evaporite ratio threshold value, the value range of the 6th aspiration ratio threshold value is 3.1~ 3.9.It not only can avoid not considering under single cylinder and twin-tub mode caused by the difference of the refrigerating/heating ability of identical frequency Serious consequence, and biggish operating pressure can be kept for a long time to avoid air conditioner, reduce the load of each operation component, from And not only prevent from shortening the service life of associated components, but also resulting components damage, failure can be prevented etc. after other Fruit.
Optionally, the value range of the 4th temperature threshold is 42~49 DEG C；Wherein, in entire air conditioner or transfiguration In increasing enthalpy control system, the general allowed band of delivery temperature is 20~120 DEG C.But if higher temperature is kept for a long time, meeting The CPU in air conditioner is seriously affected, the normal operation of controller etc. shortens the service life of electronic device.It is envisaged that Since the refrigerating capacity of the same running frequency of compressor under the refrigerating capacity and twin-tub mode of single cylinder mode compression machine differs greatly, so After air conditioner is switched to twin-tub mode, to whether the 4th temperature threshold of the switching of increasing enthalpy is also required to be transported according to twin-tub mode Actual demand in row situation is judged.It is used as the 4th temperature threshold by 42~49 DEG C, air conditioner is operated based on this The switching of mode can not only make to avoid single cylinder and the difference of the refrigerating/heating ability of identical frequency under twin-tub mode is not considered At serious consequence, and higher temperature can be kept for a long time to avoid the delivery temperature of compressor, and then air-conditioning can be made The other component of device operates normally, and prevents high temperature bring service life from shortening.
Optionally, the value range of the 4th evaporite ratio threshold value is 4.5~5.2.It is similar to above, it is cut by air conditioner After being changed to twin-tub mode, to whether the 4th evaporite ratio threshold value of the switching of increasing enthalpy is also required to according in the case of twin-tub mode operation Actual demand is judged.It is used as the 4th evaporite ratio threshold value by 4.5~5.2, operation mode is carried out to air conditioner based on this Switching, not only can be to avoid not considering under single cylinder and twin-tub mode caused by the difference of the refrigerating/heating ability of identical frequency Serious consequence, and biggish operating pressure can be kept for a long time to avoid air conditioner, reduce the load of each operation component, from And not only prevent from shortening the service life of associated components, but also resulting components damage, failure can be prevented etc. after other Fruit.
Optionally, similar with the 4th evaporite ratio threshold value, the value range of the 4th aspiration ratio threshold value is 4.5~ 5.2.It not only can avoid not considering under single cylinder and twin-tub mode caused by the difference of the refrigerating/heating ability of identical frequency Serious consequence, and biggish operating pressure can be kept for a long time to avoid air conditioner, reduce the load of each operation component, from And not only prevent from shortening the service life of associated components, but also resulting components damage, failure can be prevented etc. after other Fruit.
Optionally, after the step 500, the control method of the air conditioner further include:
Step 700, judge whether first parameter meets the 6th preset condition；
If meeting the 6th preset condition, the air conditioner is switched to single cylinder operation mode (return step 600).
It herein, is that the air conditioner is switched to twin-tub operation mould for whether meeting the judgement of the 6th preset condition It is carried out after formula.First parameter meets the 6th preset condition, shows the load reduction of air conditioner, and single cylinder is only taken to operate mould Formula, compressor can meet the needs of air conditioner with lower running frequency；In addition the decaying inside air conditioner is also shown It also reduces or disappears, the refrigerating capacity or heating capacity of air conditioner have been higher than normal demand.
In this way, the air conditioner is switched to single cylinder operation mode, both can satisfy sky by the judgement to the first parameter The demand of device is adjusted, and the energy consumption of air conditioner can be reduced, improves the Energy Efficiency Ratio of air conditioner；In addition, being carried out by the first parameter The large change of refrigerating capacity or heating capacity may be implemented in switching between single cylinder and twin-tub, so that switching is more acurrate.
Optionally, when meeting following condition, determine that first parameter meets the 6th preset condition: the target Running frequency is less than the 6th frequency threshold.
The running frequency is less than the 6th frequency threshold, it is meant that the compressor is run with lower running frequency To meet the refrigeration or heating needs of air conditioner；When in other words meeting six preset conditions, show the load of air conditioner compared with It is low.
In the case, the air conditioner is switched to single cylinder operation mode, not only can satisfy the demand of air conditioner, but also can To reduce the energy consumption of air conditioner, the Energy Efficiency Ratio of air conditioner is improved.
Optionally, the value range of the 6th frequency threshold is 30~40Hz.
Wherein, in entire air conditioner or transfiguration increasing enthalpy control system, the range of compressor operating frequency is 20~ 120Hz, the operation in the frequency range not will lead to the instant failure (being out of order in the very short time) of compressor, if but compressing Captain keeps the upper frequency within the scope of this to run the time, can be still brought to compressor compared with macrolesion, shorten making for compressor Use the service life.It is envisaged that due to the same running frequency of compressor under the refrigerating capacity and twin-tub mode of single cylinder mode compression machine Refrigerating capacity differ greatly, so after air conditioner is switched to twin-tub mode, to whether switching back into the 6th frequency of single cylinder mode Rate threshold value is also required to be judged according to the actual demand in the case of twin-tub mode operation.Using 30~40Hz as the 6th frequency threshold Value controls the switching that the air conditioner carries out single cylinder operation mode and twin-tub operation mode, not only can be to avoid not considering single cylinder It, and can be long to avoid compressor with serious consequence caused by the difference of the refrigerating/heating ability of identical frequency under twin-tub mode Time keep upper frequency, and then can to avoid brought to compressor prevented compared with macrolesion shorten compressor service life；Together When can also avoid high running frequency bring noise.
Optionally, after the step 900, the control method of the air conditioner further include:
Step 1100, judge whether first parameter meets the 6th preset condition；
If meeting the 6th preset condition, the air conditioner is switched to single cylinder operation mode (return step 600).
In this way, it is similar with the step 700, it is to sentence to whether first parameter meets the 6th preset condition It is disconnected, unlike, this step is that the air conditioner under twin-tub increasing enthalpy operation mode is judged and switched, thus by first The air conditioner is switched to single cylinder operation mode by twin-tub increasing enthalpy operation mode, both can satisfy air conditioner by the judgement of parameter Demand, and the energy consumption of air conditioner can be reduced, improve the Energy Efficiency Ratio of air conditioner；In addition, carrying out single cylinder by the first parameter The large change of refrigerating capacity or heating capacity may be implemented in switching between twin-tub, so that switching is more acurrate.
In addition, also determining whether to be switched to single cylinder mode under twin-tub increasing enthalpy mode, so as to reach three modes Between smooth switching, avoid switching and not prompt enough (be switched to single cylinder operation mould again if be switched to after twin-tub operation mode Formula will lead to the delay on switching time due to also needing to reacquire data judgement etc. under twin-tub operation mode) caused by The consume of compressor and other parts inside air conditioner etc. and the energy consumption of air conditioner are excessive etc..
Optionally, after the step 500, the control method of the air conditioner further include:
Step 1200, judge whether first parameter meets the 6th preset condition and whether second parameter meets Two preset conditions；
6th preset condition is for judging whether to be switched to single cylinder operation mode；Second preset condition is For judging whether to be switched to twin-tub increasing enthalpy operation mode.Due to judging respectively the first parameter and the second parameter, institute With there are two kinds of simultaneous possibility of situation；This possibility can make the control logic of control method cause confusion, lead to nothing Method is effectively switched.
Step 1300, if first parameter meets the 6th preset condition and second parameter meets described second Preset condition then externally reports an error.
By reporting an error, logical miss caused by can occurring simultaneously to avoid two kinds of situations, consequently facilitating to the reality of air conditioner Border situation is judged, and carries out the accurate switching of operation mode.
Optionally, described the air conditioner is switched to twin-tub operation mode to specifically include:
Step 510, the operation mode of the air conditioner is switched to twin-tub operation mode；
Here, it should be clear that, in four operation modes of air conditioner, the Rule of judgment under different operation modes is had Changed.Wherein, the Rule of judgment difference very little under single cylinder operation mode and single cylinder increasing enthalpy operation mode is write from memory in the application Think identical；Similar, also the Rule of judgment under twin-tub operation mode and twin-tub increasing enthalpy operation mode is defaulted as identical.
Variation to the operation mode of air conditioner, including be switched to twin-tub operation mode and remain twin-tub operation mode, This step is switched to twin-tub operation mode only for therein.
It should be noted that being defaulted as herein identical, only think that the difference between them is not sufficient to seriously affect The control effect of variable volume system；But after air conditioner is switched to new operation mode, the operating of a period of time is still needed, The parameters under current mode can be just made to tend towards stability and (tend to the actual conditions under corresponding current mode).
Step 520, control compressor runs the first preset time with current goal frequency；
Herein, the first preset time is run with current goal frequency, can makes the parameters under air conditioner can Enough meet the actual conditions under current mode.For example, in the case where the refrigeration demand of air-conditioning is constant, single cylinder operation Compressor operating frequency under mode is 70Hz, and the compressor operating frequency under twin-tub operation mode is 50Hz, meanwhile, fortune Delivery temperature during row etc. is also different；First preset time is set, so that it may so that the parameters of air conditioner are pressed It gradually adjusts, tends towards stability according to the actual conditions under current mode, to improve to operating condition under current mode Parameter acquisition accuracy.
Optionally, the value range of first preset time is 5-10min；So that air conditioner reaches current Steady operational status under operation mode.
Step 530, judge whether the air conditioner triggers the protected mode of the compressor；
Wherein, the protected mode of the compressor includes frequency reducing protection and raising frequency protection；Such as the bad caused temperature that radiates Height is spent, condenser is messy, will lead to the temperature that air conditioner internal temperature is higher than anticipation, may trigger the point of limit frequency reducing (i.e. It is frequency reducing protection, can be first to compressor frequency reducing)；Electric current has exception, very high, also can frequency reducing be protected, in this case, meeting Cause compressor that scheduled target frequency is not achieved, so that judging according to target operating frequency the operation of compressor Lose original accuracy.
Wherein, delivery temperature, external disk temperature, inner disc temperature, electric current, module temperature is excessively high, can all trigger the drop of compressor Frequency is protected；In addition, compressor very low frequency when, there is the degree of superheat, the problem of liquid is returned in oil return, therefore underfrequency protection occur, make The actual motion frequency for obtaining compressor will not be too low.
If triggering, the control compressor is returned with current goal frequency and runs the first preset time (return step 520)。
In this step, the control compressor is returned with current goal frequency and runs the first preset time, is substantially exactly Again target frequency is judged, as long as trigger protection mode, current mode (twin-tub operation mode) will be rested on Under, no longer switch over.
In this way, air conditioner can be made to reach the steady operational status under current mode by operation a period of time, To improve the accuracy of the operating parameter acquired under current mode, and then accurately judged；In addition, by pressure The judgement of protecting compressor mode avoids actual motion frequency and target operating frequency caused by compressor trigger protection mode Inconsistent situation further improves the accuracy of judgement.
Optionally, after the step 600, the control method of the air conditioner further include:
Step 1400, judge whether second parameter meets third preset condition；
Whether meet the first preset condition, is the judgment basis of single cylinder mode and twin-tub pattern switching；It is being switched to After single cylinder mode, we also need to further determine whether to need increasing enthalpy, that is to say and single cylinder operation mode is maintained still to be switched to Single cylinder increasing enthalpy operation mode.
It is that the air conditioner is switched to the laggard of single cylinder operation mode for whether meeting the judgement of third preset condition Capable.Second parameter meets the third preset condition, shows that the load of air conditioner is very high, only takes single cylinder operation mode, needs Compressor is wanted just to can satisfy the demand of air conditioner with high running frequency；In addition also show inside air conditioner there may be Decaying, further reduced the refrigerating capacity or heating capacity of air conditioner.
In addition, the third preset condition and first preset condition do not have intersection, can make to whether increasing enthalpy Judgement, without departing from determination range before, to prevent the problem of logic error etc. influences air conditioner normal control.
Wherein, described herein there is no intersection, refer to the case where being not in while meeting two preset conditions appearance, Illustrate by taking this step as an example, as the second parameter would not meet third preset condition when meeting the first preset condition；Full When sufficient third preset condition, the first preset condition would not be met；Second parameter will not meet the first preset condition and simultaneously Three preset conditions.
Similarly, the described of other parts appearance does not have intersection in the application, also illustrates that identical meaning.
Step 1500, if meeting the third preset condition, the air conditioner is switched to single cylinder increasing enthalpy operation mode；
In the case where meeting the third preset condition, the air conditioner is switched to single cylinder increasing enthalpy operation mode, is led to Increasing enthalpy is crossed, the decaying generated inside air conditioner can be reduced, to reduce air conditioner internal environment from another point of view to compressor Compression effectiveness influence, and then increase air conditioner refrigerating capacity or heating capacity；Compressor is also avoided with high fortune Line frequency operation, plays Noise Reduction.
Step 1600, judge whether second parameter meets the 5th preset condition；
It herein, is that the air conditioner is switched to single cylinder increasing enthalpy behaviour for whether meeting the judgement of the 5th preset condition It is carried out after operation mode.Second parameter meets the 5th preset condition, shows the load reduction of air conditioner, only takes list Cylinder increasing enthalpy operation mode, compressor can meet the needs of air conditioner with lower running frequency；In addition air-conditioning is also shown Decaying inside device is also reduced or is disappeared, and the refrigerating capacity or heating capacity of air conditioner have been higher than normal demand.
In addition, the 5th preset condition and first preset condition do not have intersection, can make to whether increasing enthalpy Judgement, without departing from determination range before, to prevent the problem of logic error etc. influences air conditioner normal control.
5th preset condition and the third preset condition do not have intersection, and list can be switched in this way by preventing Cylinder operation mode, the logic error that can also be switched to single cylinder increasing enthalpy operation mode occur.
If meeting the 5th preset condition, the air conditioner is switched to single cylinder operation mode (return step 600).
In this way, by the way that the air conditioner is switched to single cylinder operation mode, the demand of air conditioner not only can satisfy, but also can be with The energy consumption for reducing air conditioner, improves the Energy Efficiency Ratio of air conditioner.
In this way, by setting third preset condition and the 5th preset condition, by air conditioner in single cylinder operation mode and single cylinder It is switched between increasing enthalpy operation mode, to not only can satisfy the demand of air conditioner, but also the energy consumption of air conditioner can be reduced, mentioned The Energy Efficiency Ratio of high air conditioner；The decaying generated inside air conditioner can also be reduced simultaneously, avoid compressor with high operation Frequency operation, plays Noise Reduction.
Optionally, when meeting any one in following condition, it is default to determine that second parameter meets the third Condition:
Condition one: the delivery temperature is greater than third temperature threshold and less than the first temperature threshold；
Condition two: the ratio of the condensation temperature and the evaporating temperature is greater than third evaporite ratio threshold value and steams less than first Hair compares threshold value；
Condition three: the ratio of the condensation temperature and the suction temperature is greater than third aspiration ratio threshold value and inhales less than first Gas compares threshold value.
Meet that preset condition is similar, and above three condition respectively corresponds three embodiments to above-mentioned determination, we are with exhaust It is illustrated for temperature.The delivery temperature is greater than third temperature threshold and less than the first temperature threshold, it is meant that in single cylinder (regardless of whether increasing enthalpy), the running environment (internal operating environment of the air conditioner) of the compressor is poor under mode, exists Attenuation or caused by decaying it is more；When in other words meeting third preset condition, show that the load of air conditioner is higher.
In the case, the air conditioner is switched to single cylinder increasing enthalpy operation mode, by increasing enthalpy, air conditioner can be reduced The decaying that inside generates, to reduce influence of the air conditioner internal environment to the compression effectiveness of compressor from another point of view, in turn Increase the refrigerating capacity or heating capacity of air conditioner；It also avoids compressor to run with high running frequency, plays noise reduction Effect.

Optionally, similar with the third evaporite ratio threshold value, the value range of the third aspiration ratio threshold value is 2.5~ 3.5.Biggish operating pressure can be kept for a long time to avoid air conditioner in this way, reduces the load of each operation component, thus not Only prevent from shortening the service life of associated components, and other consequences such as can prevent resulting components damage, failure.
Optionally, when meeting any one in following condition, it is default to determine that second parameter meets the described 5th Condition:
Condition one: the delivery temperature is less than the third temperature less than the 5th temperature threshold, the 5th temperature threshold Threshold value；
Condition two: the ratio of the condensation temperature and the evaporating temperature is steamed less than the 5th evaporite ratio threshold value, the described 5th Hair is less than the third evaporite ratio threshold value than threshold value；
Condition three: the ratio of the condensation temperature and the suction temperature is inhaled less than the 5th aspiration ratio threshold value, the described 5th Gas is less than the third aspiration ratio threshold value than threshold value.
Meet that preset condition is similar, and above three condition respectively corresponds three embodiments to above-mentioned determination, we are with exhaust It is illustrated for temperature.The delivery temperature is less than the 5th temperature threshold, it is meant that (regardless of whether increasing under single cylinder mode Enthalpy) compressor running environment (internal operating environment of the air conditioner) preferably, not will cause decaying or caused by Decaying is few；When in other words meeting five preset conditions, show that the load of air conditioner is lower.
In the case, the air conditioner is switched to single cylinder operation mode, not only can satisfy the demand of air conditioner, but also can To reduce the energy consumption of air conditioner, the Energy Efficiency Ratio of air conditioner is improved.
