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 make room by improving the running frequency of compressor The surface temperature of interior heat exchanger is reduced to than relatively low temperature levels, so, flows through the steam meeting in the room air of indoor set Dew is condensed on outdoor heat exchanger surface, the moisture content of room air is reduced, so that indoor environment humidity gradually reduces 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, it is of the invention by its rotating speed with indoor fan by taking summer condition as an example Change is combined, wherein, the wind speed of indoor fan of the present invention changes according to high wind, the alternate form of low wind, can simulate nature The air-supply effect of wind, experience so as to improve the usage experience of user and air-supply；Meanwhile when blower fan is run with high wind indoors, control The running frequency of compressor processed is run with relatively low frequency, to avoid the temperature of indoor heat exchanger is too low from causing leaving air temp to be subcooled The problem of, ensure that the wind pushing temperature that user experiences can maintain convenient temperature levels, prevent user from cold occur Discomfort is felt；And indoor fan controls the running frequency of compressor to be run with higher frequency when being run with low wind, so, The coolant quantity for being delivered to indoor set can be improved, to reduce the temperature of indoor heat exchanger, improves the dew for flowing through indoor heat exchanger Condensation number, so as to reach the purpose to be dehumidified to indoor environment, the humidity of indoor environment is maintained to suitable humidity Condition, now, because indoor fan is run with low wind speed, therefore the low temperature cold air for being blown into indoor environment is less, therefore, Can reduce because air conditioner dehumidification operation and caused by indoor environment temperature decline adverse effect, to maintain indoor environment temperature condition Stability.

In embodiment, after user is set after the indoor temperature for it is expected to reach, at one corresponding with the preset temperature In temperature range and humidity range, i.e. temperature humidity range, in the temperature humidity range, user may feel that it is more comfortable, this In, target temperature humidity range is corresponding with the comfortable grade of body-sensing setting of human body, for example, the most comfortable corresponding humiture of human body body-sensing Scope is target temperature range and target humidity scope.

Here, design temperature and target temperature range and the corresponding relation of target humidity scope can be pre-saved, that is, is directed to Each preset temperature, multiple human bodies can be tested, the temperature and humidity of human body sensory the most comfortable, is obtained corresponding to acquisition In the setting regions of preset temperature, the first humiture corresponding with the setting comfortable grade of body-sensing of multiple human body collecting samples, and According to the first humiture, it is determined that target temperature humidity range corresponding with preset temperature, and preserve corresponding relation.Such as：Setting temperature Degree is 25 °, and now, the first temperature range is between 23.5 ° -27 °, and the first humidity range is in relative humidity 40%-60% Between, most of user can feel most comfortable, and therefore, multiple first body-sensing humitures are included in 23.5 ° -27 DEG C of temperature, phase , can be 23.5 ° -27 ° by temperature among humidity 40%-60% scope, humidity 40%-60% determines corresponding with design temperature Target temperature humidity range, and preserving between 23.5 ° -27 ° of 25 ° of preset temperature and target humiture temperature, humidity 40%-60% it Between corresponding relation.

So as to which the preset temperature of preservation can be as shown in table 1 with the corresponding relation of target temperature humidity range：

Preset temperature	Target temperature humidity range
		30°	28-30.5 ° of temperature, humidity 30%-50%
28°	26-29 ° of temperature, humidity 30%-60%
		26°	25-28.5 ° of temperature, humidity 30%-60%
…	…

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 Target temperature humidity range corresponding to constant temperature degree.As shown in table 1, current preset temperature is 26 °, then the target temperature humidity range obtained For 25-28.5 ° of temperature, humidity 30%-60%.

Therefore, when air-conditioning, which is opened, to be run, user inputs the indoor temperature of setting by remote control or display panel, i.e., It can determine that the target temperature range and target humidity scope corresponding to the indoor temperature of the setting；And by current indoor temperature and Indoor humidity, compared with target temperature range and target humidity scope, if current indoor temperature is in target temperature Scope, indoor humidity are in target temperature range, then the current running status of air-conditioning maintenance can be controlled constant；And if current Indoor temperature be not at target temperature range, indoor humidity is not at target temperature range, then need control air-conditioning operation State, to adjust indoor temperature and indoor humidity, until indoor temperature is in target temperature range, indoor humidity is in target In temperature range.

In one embodiment, when current indoor temperature is not at target temperature range, current indoor humidity is not at target Temperature range when, the present invention i.e. control blower fan is run with sinusoidal or near sinusoidal wind speed version, the wind speed of blower fan Change is in periodically rise or reduces, it is ensured that the stationarity of blower fan wind speed change so that the air-out air-flow of air-conditioning Air-out wind speed is more steadily releived, so as to build the air-supply effect of natural wind for user.

For example, Fig. 1 is the schematic diagram that the blower fan wind speed according to shown by an exemplary embodiment is changed with sinusoidal form, figure In showing, the indoor fan of air-conditioning sinusoidally changes, and within the t1-t2 periods, the wind speed of indoor fan is by middle air speed value Gradually risen at Vmid to maximum wind velocity value Vmax, and within t2-t3 period, the wind speed of indoor fan is then by maximum wind velocity It is gradually decrease at value Vmax at minimum windspeed value Vmin, within t3-t4 period, the wind speed of indoor fan is by minimum windspeed value Vmin is gradually risen to middle air speed value Vmin, and so, t1-t4 may make up a complete cycle of blower fan wind speed change.In sky Tune, which adjusts current indoor temperature to target temperature range, current indoor humidity, to be adjusted to before target humidity scope, indoor wind Machine can periodically adjust the wind speed change of blower fan with the wind speed version.

Or in another embodiment, when current indoor temperature is not at target temperature range, current indoor humidity is not located In target temperature range when, the present invention i.e. control blower fan is run with the wind speed version of cosine or approximate cosine, and preceding Sinusoidal or near sinusoidal the wind speed version stated in embodiment is similar, and the wind speed change of indoor fan is also in periodically Rise or reduction, equally can be that user build the air-supply effect of natural wind.

For example, Fig. 2 is the schematic diagram that the blower fan wind speed according to shown by an exemplary embodiment is changed with cosine form, figure In showing, the indoor fan of air-conditioning sinusoidally changes, and within t1-t2 period, the wind speed of indoor fan is then by maximum wind velocity It is gradually decrease at value Vmax at minimum windspeed value Vmin, and within t2-t3 period, the wind speed of indoor fan is by minimum windspeed Gradually risen at value Vmin to maximum wind velocity value Vmax, t1-t3 forms a complete cycle of blower fan wind speed change.In air-conditioning Current indoor temperature is adjusted to target temperature range, current indoor humidity and adjusted to before target humidity scope, indoor fan The wind speed change of blower fan can be periodically adjusted with the wind speed version.

Therefore, air-conditioning can prestore the wind speed version of the sine or cosine in previous embodiment.It is actual in air-conditioning In running, the one of which wind speed change of the sine in previous embodiment or cosine can be selected to adjust the wind speed of blower fan Change.

In one embodiment, the period of change of wind speed version is the humidity according to current humidity value and setting humidity value What mathematic interpolation obtained.Specifically, calculate the humidity deviation for determining humidity differences and the first humidity differences determined by the last time Value；Afterwards, according to humidity deviation value, the cycle duration of period of change is determined.

In the present embodiment, the wind speed of air-conditioning indoor fan adjusts process periodically repeatedly to carry out, therefore, every In cyclic flow once, the current humidity difference for determining there is current period flow can be calculated, i.e. each cycle can count Calculate the humidity differences sheet for the setting humidity value for obtaining current indoor humidity and user acquired in current period；Invent warm and humid dual control Method is in order to improve the accuracy to blower fan blast velocity control, it is determined that, it is necessary to predefine before the period of change of rotation speed of fan Identified humidity differences in the humidity differences of this cyclic flow and previous cyclic flow.

That is, the current humidity value for being set in indoor environment reaches before setting humidity value, and air-conditioning is needed before repeating m times Flow in embodiment is stated, by taking n-th therein as an example, it is determined that before period of change of the blower fan in the n-th cyclic flow, is just needed Predefine identified current humidity difference in (n-1)th cyclic flow；The Current Temperatures difference of (n-1)th time is n-th- Acquired current humidity value and the difference of setting humidity value in the cyclic flow of 1 time.

For example, by taking the process of refrigerastion of summer high temperature operating mode as an example, in continuous two 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 (n-1)th time is relatively wet Degree 70%, n-th is relative humidity 65%, and air-conditioning sets humidity differences of the humidity value as relative humidity 55%, then (n-1)th time For 15%, the humidity differences of n-th are 10%.

In this manner it is possible to further determine that current humidity difference and the humidity of the first humidity differences determined by the last time are inclined Humidity deviation value between difference, i.e. the current humidity difference of this cyclic flow and a upper cyclic flow, for example, the present invention with N-th is as this cyclic flow, then according to the n-th being calculated in previous embodiment and the current humidity of (n-1)th time Difference, you can it is 15%-10%=5% to determine 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.

Preferably, the related procedure of the period of change of the wind speed version that blower fan is determined according to humidity differences of the present invention Step was carried out in n ＞ 1 time cycle, and because the time in each cycle is shorter, therefore air-conditioning opens 2 cycles before operation Indoor temperature and humidity and leaving air temp change it is smaller, therefore the above-mentioned process step of the present invention is primarily directed to n ＞'s 2 times Cyclic flow and its follow-up cyclic flow.

Preferably, for the ease of calculating, humidity deviation value determined by the present invention is the absolute value using the numerical value.

So, according to humidity deviation value, you can determine the cycle duration of period of change.

Specifically, the cycle duration of period of change is calculated according to equation below：

L=(RH_Ki*Drh_n+RH_Kp*Prh_n)*E；

Wherein, Drh_n=| Prh_n-Prh_n-1|, Prh_n=| RH_n- RHm |,

L is the cycle duration of period of change, and RH_Ki is humidity deviation coefficient, and RH_Kp is psychrometric difference coefficient, and E is first week Phase design factor, Drh_nFor psychrometric difference deviation, Prh_nFor humidity differences, RH_nFor current humidity value, RHm is setting humidity value.

For example, in one embodiment, humidity deviation coefficients R H_Ki is 3, psychrometric difference coefficients R H_Kp is 5, period 1 meter It is 5 to calculate coefficient E, the Drh being calculated_nFor 5, Prh_nFor 20, then cycle duration L=(5*3+20*5) * 5=9.6min.

The wind speed version of blower fan is divided into high wind speed area and low wind speed area by the present invention by wind speed threshold value, i.e. when When the current wind speed of blower fan is more than wind speed threshold value, now, the wind speed of blower fan is in high wind speed area；And when the current wind speed of blower fan is small When wind speed threshold value, now, the wind speed of blower fan is in low wind speed area.In general, because blower fan is using sinusoidal or cosine wind speed Version, it is equal that blower fan, which is in high wind speed area and the duration in low wind speed area, that is, is 1/2 period of change.Therefore, meter is worked as Calculation is obtained after cycle duration L, you can duration of the blower fan in high wind speed area and low wind speed area is determined, such as the high wind in the present embodiment The duration in fast area and low wind speed area is 4.8min.

In air-conditioning practical application, RH_Ki, RH_Kp, E are the design factor being stored in advance in air-conditioning, and these calculate system Number can collect to obtain before air-conditioning products dispatch from the factory by the tune-up data of a large amount of emulation experiments.

In another embodiment, the period of change of wind speed version is with setting the wet of humidity value according to current humidity value Degree mathematic interpolation obtains.Determine that the humidity of humidity differences and the first humidity differences determined by the last time is inclined specifically, calculating Difference；Afterwards, according to humidity deviation value, when determining the compressor with cycle in second frequency operation corresponding high frequency stage It is long.

Here, equally it is exemplified by n-th control flow in previous embodiment, it is current wet in (n-1)th cyclic flow Degree difference is defined as the first humidity differences.

In the present embodiment, when blower fan is in high speed winds area, compressor is run with the relatively low first frequency of frequency, so that Obtain leaving air temp and be unlikely to too low；And when blower fan is in low wind speed area, compressor is run with the higher second frequency of frequency, this When, indoor set can carry out dehumidification operation to indoor environment, therefore, in order to improve dehumidification rate, ensure effect on moisture extraction, Ke Yigen According to humidity deviation value, compressor is determined with the cycle duration in second frequency operation corresponding high frequency stage, to ensure to be used for pair The duration in the high frequency stage that indoor environment is dehumidified can meet the time demand of dehumidification operation.

L₁=(RH_Ki*Drh_n+RH_Kp*Prh_n)*F；

Wherein, Drh_n=| Prh_n-Prh_n-1|, Pt_n=| RH_n- RHm |,

L₁For the cycle duration in high frequency stage, RH_Ki is humidity deviation coefficient, and RH_Kp is psychrometric difference coefficient, F second Computation of Period coefficient, Drh_nFor psychrometric difference deviation, Prh_nFor humidity differences, RH_nFor current humidity value, RHm is setting humidity Value.

For example, in one embodiment, humidity deviation coefficients R H_Ki is 3, psychrometric difference coefficients R H_Kp is 5, period 1 meter It is 5 to calculate coefficient E, the Drh being calculated_nFor 5, Prh_nFor 20, then the cycle duration L in high frequency stage₁=(5*3+20*5) * 5= 9.6min。

In the present embodiment, the cycle duration in high frequency stage is calculated using above-mentioned calculation formula, the week of low frequency phase Phase duration then uses default fixed duration, and therefore, the cycle duration of period of change is calculated according to equation below：

L=L₁+L₂, wherein, L is the cycle duration of period of change.

For example, the default cycle duration of the low frequency phase of air-conditioning of the present invention is 5min, the height that this workflow management obtains The cycle duration in frequency stage is 9.6min, then total cycle duration L=L of period of change₁+L₂=9.6min+5min=14.6min.

Or in another embodiment, the cycle duration of high frequency stage and low frequency phase uses default fixed duration, Then total cycle duration of period of change is two fixed duration sums.In the present embodiment, the cycle duration in high frequency stage and low The cycle duration in frequency stage can be consistent, or inconsistent.

In addition, in one embodiment, in the case where the blower fan of indoor apparatus of air conditioner is changed with sinusoidal or cosine form, wind speed The maximum wind velocity value and minimum windspeed value of version are determined according to current humidity value and the humidity differences of setting humidity value.Tool Body, calculate the humidity deviation value for determining humidity differences and the first humidity differences determined by the last time；Afterwards, it is inclined according to humidity Difference, determine the first maximum wind velocity value and the first minimum windspeed value.

In the present embodiment, the first maximum wind velocity value is calculated according to equation below：

V₁=(RH_Ki*Drh_n+RH_Kp*Prh_n)*A；

Wherein, Drh_n=| Prh_n-Prh_n-1|, Prh_n=| RH_n- RHm |,

V₁For the first maximum wind velocity value, RH_Ki is humidity deviation coefficient, and RH_Kp is psychrometric difference coefficient, and A is first maximum Wind speed coefficient, Drh_nFor psychrometric difference deviation, Prh_nFor humidity differences, RH_nFor current humidity value, RHm is setting humidity value.

For example, in the present embodiment, humidity deviation coefficients R H_Ki is 3, psychrometric difference coefficients R H_Kp is 4, the first most strong wind Fast coefficient A is 10, the Drh being calculated_nFor 5, Prh_nFor 20, then the first maximum wind velocity value V₁=(5*3+20*4) * 10= 950rpm。
