Below in conjunction with instantiation, above-mentioned operation of air conditioner control method is described further:
Example 1:
When air-conditioner is in refrigeration mode, ambient temperature is 30 DEG C, the default refrigeration output frequency of air-conditioner
Rate interval is [10Hz, 120Hz], and presetting and heating output frequency interval is [10Hz, 160Hz], then maximum refrigeration
Output frequency is 120Hz, and minimum refrigeration output frequency is 10Hz, and it is 160Hz that maximum heats output frequency,
It is 10Hz that minimum heats output frequency, the default air outlet temperature value T set by user2sIt is 24 DEG C, system
Cold temperature declines offset B1Being 3 DEG C, the default startup time is 5 minutes.Air-conditioner starts and defeated with maximum refrigeration
After going out the operation of frequency 120Hz 5 minutes, start to obtain indoor heat converter temperature value T2And learn into
T2=18 DEG C, obtain, according to formula (1), the temperature difference deviation value X that freezes1=18-(24-3)=-5 DEG C, then further root
Corresponding refrigeration frequency change rate V is understood according to predeterminated frequency change synopsis1=-50%, then, due to currently
Compressor operating frequency FoFor 120Hz, correct output frequency so can obtain freezing according to formula (3)
Fb1=Fo+Fo×V1=120Hz+ [120Hz × (-50%)]=60Hz, and Fb1=60Hz is defeated in default refrigeration
Go out in the range of frequency separation [10Hz, 120Hz], it is possible in default operation time interval (such as 120 seconds)
Interior control compressor runs according to 60Hz according to air-conditioner；When the times of 120 seconds arrive, then to indoor
The temperature of heat exchanger obtains, if now indoor heat converter temperature value T2 is 19 DEG C, then and basis
Formula (1) obtains the temperature difference deviation value X that freezes1=19-(24-3)=-2 DEG C, so-2 DEG C >-5 DEG C, the temperature difference of freezing
Variation tendency is ascendant trend, understands, according to predeterminated frequency change synopsis, the frequency change rate that freezes accordingly
V1=-20%, owing to current compressor running frequency is above-mentioned 60Hz, so obtaining according to formula (3)
Refrigeration correction output frequency Fb1=Fo+Fo×V1=60Hz+ [60Hz × (-20%)]=48Hz, and Fb1=48Hz
It is in the range of default refrigeration output frequency interval [10Hz, 120Hz], it is possible in the default operation time
Control compressor in interval (such as 120 seconds) to run according to 48Hz according to air-conditioner, according to aforesaid way class
Push away and compressor operating frequency is adjusted, until indoor heat converter temperature value T2Equal to 21 DEG C.Due to
Indoor temperature is higher when needing refrigeration, and air can absorb heat, so causing air to arrive during air-supply
The temperature of air outlet is higher than the temperature of indoor heat converter, and indoor heat converter temperature value and refrigeration temperature decline compensation
Value sum is air outlet temperature value, then T2+B1=21℃+3℃=24℃=T2s, thus overcome refrigeration temperature
Difference deviation value X1, make the temperature of air outlet reach the default air outlet temperature value T set by user2s.And
In actual application, due to T2s=24 DEG C is the temperature of air outlet, but the temperature that air is after air outlet blows out
It is because of with the high temperature air (ambient temperature described above 30 DEG C) in indoor environment, heat exchange to occur,
So temperature may raise, if to feel air temperature improper for user, can be by again
Set air outlet temperature value, make air-conditioner can carry out work according to the default air outlet temperature value after resetting
Make.
Example 2:
When air-conditioner is in heating mode, ambient temperature is 15 DEG C, the default refrigeration output frequency of air-conditioner
Interval is [10Hz, 120Hz], and presetting and heating output frequency interval is [10Hz, 160Hz], then maximum refrigeration is defeated
Going out frequency is 120Hz, and minimum refrigeration output frequency is 10Hz, and it is 160Hz that maximum heats output frequency,
The little output frequency that heats is 10Hz.Default air outlet temperature value T set by user2sIt is 26 DEG C, heats
Temperature declines offset B2Being 6 DEG C, the default startup time is 5 minutes.Air-conditioner starts and heats output with maximum
After frequency 160Hz is run 5 minutes, start to obtain indoor heat converter temperature value T2And learn as T2=26 DEG C,
Obtain heating temperature difference deviation value X according to formula (2)2=(26+6)-26=6 DEG C, the most further according to presetting frequency
Rate change synopsis understands and heats frequency change rate V accordingly2=50%, then, owing to current compressor is transported
Line frequency FoFor 160Hz, correct output frequency F so can obtain heating according to formula (4)b2=Fo+Fo
×V2=160Hz+ (160Hz × 50%)=240Hz, because it is 160Hz that maximum heats output frequency, so
Compressor can be controlled in default operation time interval (such as 30 seconds) run according to 160Hz, if warp
After adjusting several times, get sampling T2It is 32.5 DEG C, then obtains heating the temperature difference according to formula (2) inclined
Distance values X2=(26+6)-32.5=-0.5 DEG C, so-0.5 DEG C < 6 DEG C, heating difference variation trend is downward trend,
Corresponding refrigeration frequency change rate V is understood according to predeterminated frequency change synopsis2=-10%, if current compression
Machine running frequency or 160Hz, then obtaining heating correction output frequency F according to formula (4)b2=Fo+Fo
×V2=160Hz+ [160Hz × (-10%)]=144Hz, and Fb2=144Hz is to heat output frequency default
In the range of interval [10Hz, 160Hz], it is possible in default operation time interval (such as 30 seconds) internal control
Compressor processed runs according to 144Hz according to air-conditioner, analogizes to enter compressor operating frequency according to aforesaid way
Row sum-equal matrix, until indoor heat converter temperature value T2Equal to 32 DEG C.Owing to making relatively low needs of indoor temperature
Heat time, due to air air-supply during can distribute heat, so cause air arrive air outlet temperature low
In the temperature of indoor heat converter, indoor heat converter temperature value is air-out with heating the decline difference of offset of temperature
Mouth temperature value, then T2-B2=32℃-6℃=26℃=T2s, thus overcome and heat temperature difference deviation value X2, make
The temperature of air outlet reaches the default air outlet temperature value T set by user2s=26℃.And apply in reality
In, due to T2s=26 DEG C is the temperature of air outlet, but the temperature that air is after air outlet blows out be can because
Heat exchange is there is with the Cryogenic air (ambient temperature described above 15 DEG C) in indoor environment, so temperature
May therefore decrease, if to feel air temperature improper for user, can be by resetting air-out
Mouth temperature value, makes air-conditioner can be operated according to the default air outlet temperature value after resetting.
