Air-conditioning has been electrical equipment common in daily life, can be with the temperature in regulation room, you can heating or cooling so that Indoor temperature and user preset Temperature Matching.But during temperature adjustment, it frequently can lead to the change of indoor environment humidity Change, such as by increasing coolant quantity to reduce indoor environment temperature when, due to indoor heat exchanger surface temperature reduction, then may lead Cause flows through the vapour quantity increase being condensed in the air of indoor heat exchanger, so, indoor environment humidity can be caused to decline, user is past Uncomfortable sensation is dried toward that can produce.Similarly, during humidity in by air-conditioning regulation room, it is also possible to cause indoor environment temperature The change of degree, the surface temperature of indoor heat exchanger such as is reduced by increasing coolant quantity, and then dehumidifying of entering to indoor environment During, because the surface temperature of indoor heat exchanger reduces, then it can cause the Wen Duxiajiang for managing the air of indoor set blowout, this Sample, indoor environment temperature can be reduced, user often produces the sensation of cold.Therefore, existing regulation temperature or wet The air conditioning control method of the single parameters such as degree can not meet the requirement of users'comfort.
The method of warm and humid dual control provided by the present invention is taken into account indoor during regulation by adjusting the operational mode of air-conditioning The change of environment temperature and humidity, so, that is, the effect of air-conditioning temperature control is ensure that, also add the function of air-conditioning humid control.
Specifically, air-conditioning of the present invention with freeze, heat or dehumidify isotype running when, input the cold of indoor heat exchanger Matchmaker amount number can directly influence refrigeration, heating and effect on moisture extraction, and input the more of coolant quantity depend on compressor at least Running frequency, when the running frequency of compressor is higher, the coolant quantity that it is discharged into the air conditioner coolant circulatory system is also more, this Sample, the coolant quantity for flowing through indoor heat exchanger also increase therewith, and then can play the work for accelerating refrigeration, heating and dehumidification rate With;And when the running frequency of compressor is relatively low, its coolant quantity being discharged into the air conditioner coolant circulatory system is also less, so, stream Coolant quantity through indoor heat exchanger is also reduced therewith, and then can play a part of delaying process of freezing, heat and dehumidify.
Therefore, by adjusting the running frequency of compressor, it is possible to achieve to the control for the coolant quantity for inputting indoor heat exchanger, And then the purpose of regulation refrigeration, heating and effect on moisture extraction.For example, in summer high temperature operating mode, air-conditioning is typically in a chiller mode Operation, can be by improving the running frequency of compressor, to accelerate the refrigeration of refrigeration mode effect when indoor environment temperature is higher Rate, so that indoor environment temperature can be reduced to than convenient temperature regime;Or worst cold case in the winter time, air-conditioning one As run with heating mode, can be by improving the running frequency of compressor, to accelerate to heat when indoor environment temperature is relatively low The heating efficiency of pattern, so that indoor environment temperature can be brought up to than convenient temperature regime;Or in summer high humidity Under operating mode, air-conditioning can be switched to dehumidification mode operation from refrigeration mode, and can be by improving the running frequency of compressor, to add The dehumidification rate of fast dehumidification mode, so as to be that indoor environment humidity can be reduced to than convenient humidity conditions.
And during environment temperature is set close to user indoors temperature value, then it can control the running frequency position of compressor of air conditioner Put in appropriate or relatively low frequency values, so as to reach the purpose for maintaining indoor environment temperature stable;Similarly, environment indoors During the humidity value that humidity is set close to user, the running frequency position of compressor of air conditioner is also can control in appropriate or relatively low frequency Value, it can equally reach the effect for playing and maintaining indoor environment temperature stable.
Adjustment for the running frequency of compressor, the invention provides two kinds of adjustment modes:One kind is according to indoor ring The current temperature value in border and the temperature value set by user, determine the target operating frequency of compressor;Another is according to room The current temperature value of interior environment and the temperature value set by user, set with reference to the current humidity value of indoor environment and user wet Angle value, and then determine the target operating frequency of compressor.Two kinds of above-mentioned regulative modes, the first is primarily directed to indoor environment Current temperature value and set temperature value temperature difference adjustment compressor running frequency so that the running frequency of compressor can Preferentially to meet the coolant quantity needs of air-conditioner temperature regulation, suitable for the refrigeration and heating operation mode of air-conditioning;Second method It is then with reference to the current temperature value of indoor environment and the temperature difference and current humidity value of set temperature value and setting humidity value Humidity difference so that the running frequency of compressor preferentially meets the larger coolant quantity demand of parameter differences, suitable for air-conditioning Refrigeration and dehumidification operating mode.
Fig. 1 is the flow chart one of the warm and humid dual control method of air-conditioning of the present invention according to shown by an exemplary embodiment.In Fig. 1 In shown application scenarios, disclose and determine that the target of compressor is transported according to the current temperature value and set temperature value of indoor environment The related procedure of line frequency.
Specifically, as shown in figure 1, foregoing current temperature value and set temperature value according to indoor environment determines compressor Target operating frequency the step of mainly include:
S101, the current temperature value for obtaining space residing for air-conditioning;
In embodiment, air-conditioning is typically installed in the interior spaces such as parlor, bedroom and meeting room, therefore, step S101 In it is acquired be the interior spaces such as parlor, bedroom or meeting room that air-conditioning is installed current temperature value, that is to say this Acquired real-time indoor environment temperature value in secondary flow.
Preferably, air-conditioning is provided with temperature sensor, the current temperature value available for detection indoor environment.Temperature sensor Induction end can be arranged on the air inlet or casing outer wall of air-conditioning so that its detection current temperature value can be with indoor ring The actual temperature in border is same or like, so as to improve object run frequency of the present invention according to compressor determined by current temperature value The precision of rate.
S102, the Current Temperatures difference for determining current temperature value and set temperature value;
In embodiment, when air-conditioning opens operation, user can pass through the control panel on remote control or air-conditioning body Input needs the target indoor environment temperature reached, i.e. set temperature value in the present embodiment, such as in summer high temperature operating mode, user The target indoor environment temperature for needing to reach is set as 24 DEG C by remote control, then 24 DEG C are set temperature value.
It should be appreciated that if user does not input target indoor environment temperature value by remote control or control panel, The temperature value maintained when being usually then and closing acquiescence air-conditioning last time is set temperature value, setting when such as last air-conditioning shuts down Temperature value is 26 DEG C, then in the case where this air-conditioning start operation and user do not input set temperature value, last air-conditioning fortune 26 DEG C during row be this flow set temperature value.
In embodiment, in summer high temperature operating mode, the current temperature value of indoor environment is usually to be higher than set temperature value, because This, Current Temperatures difference is the difference that current temperature value subtracts set temperature value;And worst cold case, indoor environment are worked as in the winter time Preceding temperature value is typically below set temperature value, and therefore, Current Temperatures difference is the difference that set temperature value subtracts current temperature value Value.For the ease of calculating, preferably, Current Temperatures difference determined by the present invention is the difference of current temperature value and set temperature value The absolute value of value.
S103, the target operating frequency for determining according to Current Temperatures difference compressor;
In the present embodiment, the frequency adjustment procedure of compressor of air conditioner is repeatedly carried out with setting the cycle, therefore, every In cyclic flow once, the Current Temperatures difference for determining there is current period flow, the warm and humid dual control side of the present invention can be calculated Method is in order to improve the accuracy to compressor operating frequency control, before according to the target operating frequency for determining compressor, needs Identified temperature gap in the first two cycle for predefining this flow.
That is, be set in indoor environment Current Temperatures reach design temperature before, air-conditioning needs to repeat m foregoing reality Flow in example is applied, by taking n-th therein as an example, it is determined that before target operating frequency of the compressor in the n-th cyclic flow, just Need identified Current Temperatures difference in predetermined (n-1)th time and the cyclic flow of the n-th -2 times;The current temperature of (n-1)th time Degree difference is current temperature value acquired in the cyclic flow of (n-1)th time and the difference of design temperature, the n-th -2 times current Temperature gap is current temperature value acquired in the cyclic flow of the n-th -2 times and the difference of design temperature.
For example, by taking the process of refrigerastion of summer high temperature operating mode as an example, in continuous three cyclic flows, due to air conditioner refrigerating Pattern continuous service, therefore, the current temperature value detected by three cycles are gradually reduced, and such as the n-th -2 times are 30 DEG C, the N-1 times is 29 DEG C, and n-th is 27 DEG C, and the set temperature value of air-conditioning is 24 DEG C, then the Current Temperatures difference of the n-th -2 times is 6 DEG C, The Current Temperatures difference of (n-1)th time is 5 DEG C, and the Current Temperatures difference of n-th is 3 DEG C.
In this manner it is possible to further determine that Current Temperatures difference and the first temperature of the first temperature gap determined by the last time Deviation, i.e. temperature deviation value between the Current Temperatures difference of this cyclic flow and a upper cyclic flow are spent, for example, this hair It is bright using n-th as this cyclic flow, then according to the current of the n-th being calculated in previous embodiment and (n-1)th time Temperature gap, you can it is 5-3=2 DEG C to determine the first temperature deviation value.
Similarly, it can also determine that the first temperature gap and the second temperature of second temperature difference determined by its last time are inclined Difference, i.e., between this Current Temperatures difference of a upper cyclic flow and the Current Temperatures difference of its last cyclic flow Temperature deviation value, for example, this last time cyclic flow is (n-1)th cyclic flow, then its last cyclic flow is n-th -2 Secondary cyclic flow, then according to (n-1)th time and the Current Temperatures difference of the n-th -2 times being calculated in previous embodiment, you can It is 6-5=1 DEG C to determine second temperature deviation.
It should be appreciated that in order to distinguish the Current Temperatures difference in different cycles flow, it is of the invention by previous embodiment In (n-1)th cyclic flow in Current Temperatures difference be defined as the first temperature gap, it is current in the n-th -2 times cyclic flows Temperature gap is defined as second temperature difference.
Preferably, the related procedure step of the target operating frequency that compressor is determined according to Current Temperatures difference of the present invention It is to be carried out in n > 2 times cycle, because the time in each cycle is shorter, therefore air-conditioning opens the room in 2 cycles before operation The change of interior humiture and leaving air temp is smaller, therefore the above-mentioned process step of the present invention is primarily directed to n > 2 times cycle Flow and its follow-up cyclic flow.
Preferably, for the ease of calculating, temperature deviation value determined by the present invention is also the absolute value using the numerical value.
So, according to the first temperature deviation value and second temperature deviation, you can determine the target operating frequency of compressor.
It is calculated specifically, the target operating frequency of compressor carries out PID according to equation below:
Hzout=Out_gain* [Kp*Dn+Ki*Pn+Kd*(Dn- Dn-1)];
Wherein, Dn=Pn–Pn-1, Dn-1=Pn-1–Pn-2
Hzout is target operating frequency, and Out_gain is output factor, and Kp is ratio controlled quentity controlled variable, and Ki is integration control amount, Kd is differential controlled quentity controlled variable, DnFor Current Temperatures difference with last time determined by the first temperature gap the first temperature deviation value, Dn-1For the second temperature deviation of second temperature difference determined by the first temperature gap and its last time, PnFor Current Temperatures Difference, Pn-1For the first temperature gap, Pn-2For second temperature difference.
In air-conditioning practical application, Out_gain is the output factor of compressor, and each compressor type is to should determine that Output factor value;Kp, Ki and Kd are the design factor being stored in advance in air-conditioning, and these design factors can dispatch from the factory in air-conditioning products Before, collect to obtain by the tune-up data of a large amount of emulation experiments.
Therefore, the target operating frequency of compressor can be calculated according to above-mentioned calculation formula, and by the object run Setting running frequency of the frequency as compressor in this cyclic flow, by by the actual motion frequency of compressor or last time Running frequency in cyclic flow is adjusted to the target operating frequency determined, and air-conditioning can be made to export to the air conditioner coolant circulatory system Coolant quantity meet air conditioner refrigerating, heating or the coolant quantity of dehumidifying demand, and can be adapted with current working, so as to also can Play energy-saving, the effect of raising air conditioner performance.
In the present embodiment, when current temperature value reaches set temperature value, minimum frequency of the control compressor to set Operation, and the inner blower of air-conditioning is run with the slow-speed of revolution, so, indoor environment temperature can be made to maintain design temperature or close Under the temperature conditionss of design temperature, and the consumption to electric energy can be reduced, reduce the use cost of air-conditioning.

In the present embodiment, if being illustrated for the determination process of humidity differences.
In the present embodiment, the current humidity for being set in indoor environment reaches before setting humidity, and air-conditioning needs to repeat to hold Flow in m previous embodiment of row, by taking n-th therein as an example, it is determined that object run of the compressor in the n-th cyclic flow Before frequency, it is necessary to predefine identified current humidity difference in (n-1)th time and the cyclic flow of the n-th -2 times;(n-1)th Secondary current humidity difference is the difference of current humidity value acquired in the cyclic flow of (n-1)th time and setting humidity, the The current humidity difference of n-2 times is the difference of current humidity value acquired in the cyclic flow of the n-th -2 times and setting humidity.
For example, by taking the process of refrigerastion of summer high temperature operating mode as an example, in continuous three cyclic flows, due to air conditioner refrigerating Pattern continuous service, therefore, the current humidity value detected by three cycles are gradually reduced, and such as the n-th -2 times are relatively wet Degree 64%, (n-1)th time is relative humidity 62%, and n-th is relative humidity 59%, and air-conditioning sets humidity value as relative humidity 50%, then the current humidity difference of the n-th -2 times is relative humidity 14%, and the current humidity difference of (n-1)th time is relative 12%, the The current humidity difference of n times is relative humidity 9%.
In this manner it is possible to further determine that the first wet of current humidity difference and the first humidity differences determined by the last time Deviation, i.e. humidity deviation value between the current humidity difference of this cyclic flow and a upper cyclic flow are spent, for example, this hair It is bright using n-th as this cyclic flow, then according to the current of the n-th being calculated in previous embodiment and (n-1)th time Humidity differences, you can it is 14%-12%=2% to determine the first humidity deviation value.
Similarly, it can also determine that the second humidity of the first humidity differences and the second humidity differences determined by its last time is inclined Difference, i.e., between this current humidity difference of a upper cyclic flow and the current humidity difference of its last cyclic flow Humidity deviation value, for example, this last time cyclic flow is (n-1)th cyclic flow, then its last cyclic flow is n-th -2 Secondary cyclic flow, then according to (n-1)th time and the current humidity difference of the n-th -2 times being calculated in previous embodiment, you can It is 12%-9%=3% to determine the second humidity deviation value.
It should be appreciated that in order to distinguish the current humidity difference in different cycles flow, it is of the invention by previous embodiment In (n-1)th cyclic flow in current humidity difference be defined as the first humidity differences, it is current in the n-th -2 times cyclic flows Humidity differences are defined as the second humidity differences.
Preferably, for the ease of calculating, humidity deviation value determined by the present invention is also the absolute value using the numerical value.
So, according to the first humidity deviation value and the second humidity deviation value, you can determine the second running frequency of compressor.
It is calculated specifically, the second running frequency of compressor carries out PID according to equation below:
Hz2=Out_gain* [Kp*dn+Ki*pn+Kd*(dn- dn-1)];
Wherein, dn=pn–pn-1, dn-1=pn-1–pn-2
Hz2 is second running frequency, and Out_gain is output factor, and Kp is ratio controlled quentity controlled variable, and Ki is integration control Amount, Kd are differential controlled quentity controlled variable, dnFor current humidity difference and the first humidity deviation of the first humidity differences determined by the last time Value, dn-1For the second humidity deviation value of the second humidity differences determined by first humidity differences and its last time, pnFor institute State current humidity difference, pn-1For first humidity differences, pn-2For second humidity differences.
Therefore, the second running frequency of compressor can be calculated according to above-mentioned calculation formula, calculated with reference to foregoing The first running frequency arrived, you can determine the target operating frequency of compressor.Preferably, the present invention is by the first running frequency and the The larger target operating frequency as compressor of numerical value in two running frequencies, and using the target operating frequency as this week The setting running frequency of compressor in phase flow, by by the fortune in the actual motion frequency of compressor or last cyclic flow Line frequency is adjusted to the target operating frequency determined, and air-conditioning can be made to export to the coolant quantity of the air conditioner coolant circulatory system and meet sky The coolant quantity demand of cold, heating or dehumidifying is modulated, and can be adapted with current working, it is energy-saving so as to can also play, Improve the effect of air conditioner performance.
In the present embodiment, the first running frequency is the minimum operation that air-conditioning carries out compressor required during temperature control Frequency, the second running frequency are the minimum running frequency that air-conditioning carries out compressor required during humid control, therefore, the present invention By for the larger target operating frequency for being chosen to be compressor of numerical value in the first running frequency and the second running frequency so that compression The running frequency of machine can meet the needs of air-conditioner temperature control and humid control.
In the present embodiment, when current temperature value reaches set temperature value, compressor can be equally controlled to set Minimum frequency is run, and the inner blower of air-conditioning is run with the slow-speed of revolution, so, indoor environment temperature can be made to maintain design temperature Or close under the temperature conditionss of design temperature, and the consumption to electric energy can be reduced, reduce the use cost of air-conditioning.
In addition, in above-mentioned multiple embodiments during the regulation of the running frequency of compressor, along with being changed in input chamber The change of the coolant quantity of hot device, the leaving air temp of air-conditioning can also be affected, for example, switch to dehumidification mode to run in air-conditioning, The running frequency of compressor improves, refrigerant input quantity increase when, the leaving air temp of air-conditioning also decreases, and in turn results in user not Suitable, therefore, in order to avoid influence of the temperature change to user, air-conditioning of the invention is additionally provided with electric heater unit, electrical heating dress The air that putting can blow out to air-conditioning heats, so as to play a part of improving air-out gas flow temperature.
In general, existing electric heater unit is mainly the heating condition of application in the winter time, and the present invention can then be answered Used in the operational mode such as refrigeration or dehumidifying, so as to improve the utilization rate of electric heater unit.Specifically, filled by adjusting electrical heating That puts is turned on and off, and output frequency during unlatching, it is possible to achieve to the temperature control for the air-out air-flow for being blown into indoor environment System, and then realize air-out gas flow temperature constant purpose when air-conditioning is run with the isotype that dehumidifies so that do not influenceing indoor refrigeration In the case of, avoid the occurrence of because of the fluctuations in indoor temperature caused by pattern switching etc. the problem of.
