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

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

Pattern;The third is then to combine above two ways, suitable for the heat demand that parameter differences are larger, suitable for the refrigeration of air-conditioning
And dehumidification operating mode.
Fig. 3 is the flow chart 3 of the warm and humid dual control method of air-conditioning of the present invention according to shown by an exemplary embodiment.In Fig. 3
In shown application scenarios, output when determining whether to open electrical heating and electrical heating unlatching according to current humidity value is disclosed
The related procedure of power.
Specifically, as shown in figure 3, the key step of the first foregoing electrically heated adjustment mode includes:
S310, according to set temperature value, determine target humidity scope;
Here, the corresponding relation of set temperature value and target humidity scope can be pre-saved, i.e., for each design temperature,
Multiple human bodies can be tested, the humidity of human body sensory the most comfortable corresponding to acquisition, obtain the setting regions in design temperature
It is interior, the humidity value corresponding with the setting comfortable grade of body-sensing of multiple human body collecting samples, and according to multiple humidity values, it is determined that with setting
Target humidity scope corresponding to constant temperature degree, and preserve corresponding relation.Such as:Design temperature is 25 DEG C, and now, humidity is relatively wet
Spend between 40%-60%, most of user can feel most comfortable, therefore, can determine humidity 40%-60% with setting 25 DEG C of temperature
Corresponding target humidity scope, and preserve the corresponding relation between 25 ° of design temperature and target humidity scope 40%-60%.
So as to which the design temperature of preservation can be as shown in table 1 with the corresponding relation of target humidity scope:
Design temperature |
Target humidity scope |
30℃ |

… |
Table 1
Here, can be according to the corresponding relation of the preset temperature and target temperature humidity range of preservation, it is determined that currently being set with air-conditioning
Current goal humidity range corresponding to constant temperature degree.As shown in table 1, for the temperature currently set as 28 °, then the current goal obtained is wet
Degree scope is 30%-60%.
S321, when current humidity value is not in target humidity scope, then control open electrical heating;
In the present embodiment, when current humidity value is not in target humidity scope, then compressor in the aforementioned embodiment
After running frequency regulation, or, when air-conditioning needs to switch to dehumidification mode, coolant quantity output increase, flow through indoor heat exchanger
Coolant quantity also change therewith, therefore, the temperature of air-conditioner air outlet can be caused to change, leaving air temp reduce, then need out
Electrical heating is opened, and heat is conveyed to air-out air-flow, to compensate the temperature that air-out air-flow reduces by coolant quantity increase.
In embodiment, current humidity value does not include current humidity value less than target humidity scope in target humidity scope
Lower limit, and current humidity value are higher than the upper limit of target humidity scope, for example, the target humidity model corresponding to a certain design temperature
It is RH to enclose for (RH1, RH2), current humidity value, then in the case of RH < RH1 or RH > RH2, you can meet that electrical heating is opened
The condition opened.
S322, when current humidity value is in the target humidity scope, then be not turned on electrical heating;
For example, in the case of current humidity value RH1 < RH < RH2, that is, meet the condition that electrical heating is not turned on.
In general, it is in each periodic stream because the present invention determines whether to open electrically heated judgement flow according to humidity value
It can be carried out in journey, therefore, if air-conditioning is opened in the first cyclic flow of operation, current humidity value meets to be not turned on electrical heating
Condition, then be not turned on electrical heating;If first cyclic flow meets to open electrically heated condition, in addition to first cyclic flow
Follow-up wherein some cyclic flow meet to be not turned on electrically heated condition, then be not some cyclic flow in this prior
In electrical heating is closed again, current electrically heated power output is usually maintained in the cycle and subsequent cycle flow not
Become, so, because having met requirement of the user to indoor humidity in the cycle, illustrate in the cycle and subsequent cycle
Air-conditioning work when, the heat of electrical heating output can compensate the leaving air temp because of caused by the operation power adjustment of compressor
Decline change.
Similarly, other two kinds of electrically heated control methods in subsequent embodiment can also use similar with the present embodiment
Mode.
In another embodiment, disclose and determine whether that opening electrical heating and electrical heating opens according to Current Temperatures difference
When power output related procedure;Specifically, the key step of second foregoing of electrically heated adjustment mode includes:When work as
For preceding temperature gap not in target temperature difference scope, then electrical heating is opened in control;And when Current Temperatures difference is in the target
During temperature difference scope, then electrical heating is not turned on.
