Embodiment one
Fig. 3 is the flow chart of the defrosting method of air-conditioning of the present invention.Wherein, air-conditioning is under heating mode and runs.
As shown in figure 3, the defrosting method of the air-conditioning of the embodiment of the present invention, comprising the following steps:
S101: it is in frosting state in air-conditioning, the air conditioning capacity of air-conditioning in the first preset duration is detected.
It should be noted that being based on air-conditioner system above-mentioned, for air-conditioning in heating process, outdoor heat exchanger can be because
Condensation and frosting, therefore, it is necessary to whether be in frosting state to air-conditioning to judge, with air-conditioning be in frosting state it
After judge whether to need to carry out defrost.
It should also be noted that, if air-conditioner outdoor unit frosting, can make due to needing to absorb heat when air-conditioner outdoor unit is condensed
Temperature near air-conditioner outdoor unit further decreases, that is, the efficiency that outdoor heat exchanger carries out heat absorption condensation reduces, and then leads to room
Interior heating capacity can also further decrease, and therefore, can be judged by the temperature to air-conditioning each position to determine whether air-conditioning is located
In frosting state, also it can determine whether air-conditioning is in frosting state by heating capacity in air conditioning chamber.
Specifically, after air-conditioning heating runs a period of time, such as 4-8 minutes, acquire at least one temperature detection of air-conditioning
The temperature of point determines that air-conditioning is in frosting state if the temperature of temperature detecting point is lower than preset temperature threshold.Wherein, until
A few temperature detecting point can acquire at least one in other words for the point of temperature sensor setting each in aforementioned air-conditioner system
The temperature that a temperature sensor being arranged on air-conditioner system detects, if the temperature that the temperature sensor detects is lower than
The preset temperature threshold of the temperature monitoring point, it is determined that air-conditioning is in frosting state.
Alternatively, the indoor heating amount in the second preset duration is detected, if indoor heating amount is when second is default
Attenuation in length is more than preset attenuation, it is determined that air-conditioning is in frosting state.Wherein, the attenuation of heating capacity is latter
The difference at moment and previous moment heating capacity, for example, in the second preset duration finish time and the second preset duration start time
Heating capacity difference.
That is, when the temperature for detecting at least one temperature detecting point is lower than preset temperature threshold, or when detection
When the attenuation of heating capacity is more than preset attenuation in the second preset duration, further to air-conditioning in the first preset duration
Air conditioning capacity is detected.
It should be understood that in embodiments of the present invention, air conditioning capacity can be indoor heating amount, it may also include sensible heat energy
Power, latent heat ability.Wherein, air conditioning capacity is related to the temperature of multiple temperature detecting points and compressor frequency, in other words, can be by more
The temperature and compressor frequency of a temperature sensor detection are obtained by calculating.
S102: according to the air conditioning capacity detected, judge whether the current frosting velocity of air-conditioning exceeds preset frosting speed
Degree.
It should be noted that there is the frosting with predominantly outdoor heat exchanger of air conditioner biggish to the influence of fading of air conditioning capacity
Situation therefore can be by detecting air conditioning capacity, to judge the current frosting velocity of air-conditioning.
Specifically, as shown in figure 4, according to the air conditioning capacity detected, it is default to judge whether the frosting velocity of air-conditioning exceeds
Frosting velocity, comprising:
S201: according to the air conditioning capacity detected, air conditioning capacity is obtained in the first preset duration in the decaying of different moments
Rate.
Specifically, the first preset duration can be divided into multiple moment, successively obtained in the first preset duration, when latter
The difference with the attenuation of previous moment is carved, the rate of decay of later moment in time is obtained.
S202: if the rate of decay of different moments is gradually increased, by the rate of decay and rate of decay at current time
Threshold value is compared.
S203: if the rate of decay at current time is greater than rate of decay threshold value, it is determined that current frosting velocity exceeds
Preset frosting velocity.
That is, judging later moment in time decaying speed in the first preset duration of acquisition after the rate of decay at each moment
Whether rate is greater than the rate of decay of previous moment, if the rate of decay of later moment in time is greater than the rate of decay of previous moment, table
The frosting state of bright outdoor heat exchanger, which has begun, influences air-conditioning entirety heating efficiency, then further whether judges rate of decay
Greater than rate of decay threshold value, to determine defrost opportunity, i.e., if rate of decay is greater than rate of decay threshold value, it is determined that current knot
White speed exceeds default frosting velocity.
Wherein, according to the model of air-conditioning, the rate of decay threshold value of air-conditioning is obtained.
For example, the first preset duration can be divided into multiple moment, for example, the first moment X1, the second moment X2,
Three moment X3 ..., the n-th moment Xn, each moment corresponding heating capacity be respectively A, B, C ..., then can obtain first it is default when
The attenuation of the heating capacity at each moment in long, for example, the attenuation at the second moment is (B-A), the attenuation at third moment is
And so on (C-B), the attenuation that any time in the first preset duration can be got, since the first preset duration is divided,
The then attenuation at each moment, the rate of decay of as each moment heating capacity.It should be understood that rate of decay can also lead to
It crosses and sums or ask the other methods such as difference to obtain.
Then, judge whether the rate of decay of any later moment in time in the first preset duration is greater than the decaying of its previous moment
Rate, for example, judge whether the rate of decay (C-B) of third moment X3 is greater than the rate of decay (B-A) at the second moment, if the
The rate of decay of three moment X3 is less than or equal to the rate of decay of the second moment X2, then illustrates the indoor heating amount of third moment X3
Indoor heating amount relative to the second moment X2 is not reduced or is at the uniform velocity reduced, i.e., the frosting degree of outdoor heat exchanger is not to air-conditioning energy
Power has an impact, and persistently judges at this time rate of decay, if the rate of decay of third moment X3 is greater than the second moment X2
Rate of decay, then illustrate that the indoor heating amount of third moment X3 is significantly reduced relative to the indoor heating amount of the second moment X2,
That is the frosting degree of outdoor heat exchanger has affected air conditioning capacity, judges that the frosting of outdoor heat exchanger of air conditioner has degradating trend,
It needs further to judge whether frosting velocity exceeds preset frosting velocity.
It should be noted that since the intrinsic parameter of the air-conditioning of different model is different air-conditioning can be obtained according to the model of air-conditioning
Rate of decay threshold value, to determine whether current frosting velocity exceeds preset frosting velocity by rate of decay threshold value, prevent
Only control air-conditioning carries out the opportunity of defrost too early or too late.Specifically, judge whether the rate of decay at current time is greater than decaying
Rate-valve value, to determine that the frosting degree of outdoor heat exchanger has seriously affected air conditioning capacity, i.e., when current rate of decay
When less than or equal to rate of decay threshold value, current frosting velocity is without departing from preset frosting velocity, when current rate of decay
When greater than rate of decay threshold value, current frosting velocity exceeds preset frosting velocity.
As a result, by the rate of decay of detection different moments, and it is gradually increased in rate of decay and is greater than default decaying threshold
When value, determine that frosting velocity beyond preset frosting velocity, can accurately determine air-conditioning system when air-conditioning heating is run
Frosting situation enters defrost process for air-conditioning and provides Data safeguard.
S103: it when current frosting velocity exceeds preset frosting velocity, then controls air-conditioning and enters defrost process.
It should be understood that when current frosting velocity is without departing from preset frosting velocity, though outdoor heat exchanger has knot
Frost, but frosting velocity is smaller or frosting is relatively thin is not enough to start defrosting operation, and it is too early to will appear defrost if starting defrosting operation
The problem of heating capacity influences user experience is reduced, when current frosting velocity exceeds preset frosting velocity, outdoor heat exchanger
Frosting it is more serious, at this time carry out defrost can not only save the defrost time, additionally it is possible to the heating efficiency for guaranteeing air-conditioning, because
This then controls air-conditioning and enters defrost process when judging current frosting velocity beyond preset frosting velocity.
Further, control air-conditioning enters after defrost process, further includes: the temperature of temperature detecting point on detection air-conditioning,
Judged whether to need to exit defrost process according to temperature, when judging that air-conditioning needs to exit defrost process, then controls air-conditioning and move back
Defrost process out；Alternatively, the variation of detection air conditioning capacity judges whether to need to exit defrost stream according to the variation of air conditioning capacity
Journey then controls air-conditioning and exits defrost process when judging that air-conditioning needs to exit defrost process.
It should be noted that after air-conditioning enters defrost process, in order to energy saving, guarantee the heating needs of user, need
It to control air-conditioning in time after defrost and exit defrost process.
Specifically, detect air-conditioning on temperature detecting point temperature, such as on aforementioned air-conditioner system it is any one or more
The temperature of temperature detecting point, judges whether the temperature of temperature detecting point reaches preset temperature, if it is, determining that air-conditioning needs move back
Defrost process out, control air-conditioning exit defrost process；If it is not, then determining that air-conditioning continues there is still a need for defrost, control air-conditioning is carried out
Defrost.In addition, also detectable air conditioning capacity judges whether to need to exit defrost process, i.e., in sky according to the variation of air conditioning capacity
Tune ability exits defrost process when being gradually recovered.
In conclusion the defrosting method of the air-conditioning of the embodiment of the present invention, is in heating mode operation in air-conditioning and in knot
When white state, the air conditioning capacity of air-conditioning in the first preset duration is detected, then according to the air conditioning capacity detected, judgement
Whether the current frosting velocity of air-conditioning exceeds preset frosting velocity, when current frosting velocity exceeds preset frosting velocity
When, then it controls air-conditioning and enters defrost process.The defrosting method of the air-conditioning of the embodiment of the present invention as a result, can be according to air conditioning capacity
Judge that frosting situation is judged, to timely enter defrost process, in the case where guaranteeing air-conditioning heating effect, effectively improving
White effect.
