By control compressor running frequency, make outdoor coil pipe used temperature less than frosting temperature be more than setting value (or other rationally
Temperature) time be no more than T, to play the purpose for inhibiting outdoor unit frosting, while also reducing to indoor heating amount
It influences, improves the usage experience of user.
Description of the drawings
Fig. 1 is that the air conditioner of the present invention inhibits the broad flow diagram of frosting control method.
Specific implementation mode
To keep the embodiment of the present invention, technical solution and advantage more obvious, below in conjunction with attached drawing to the skill of the present invention
Art scheme is clearly and completely described, it is clear that and the embodiment described is a part of the embodiment of the present invention, rather than all
Embodiment.It will be apparent to a skilled person that these embodiments are used only for explaining the technical principle of the present invention, and
It is not intended to be limiting protection scope of the present invention.
As shown in Figure 1, the air conditioner of the present invention inhibits frosting control method to include the following steps：S110, in air conditioner system
In thermal process, outdoor coil pipe used temperature is obtained；S120, calculating difference D=frostings temperature-outdoor coil temperature；S130, it is on duty
When value D >=setting value, the duration T of monitoring difference D >=setting value, and after T >=setting time, control the fortune of compressor
Line frequency, so that difference D < setting values.Specifically, the method for the present invention is mainly the running frequency by controlling compressor,
And then outdoor coil temperature is controlled to realize the purpose for inhibiting frosting.
As an example, as difference D >=4, that is to say, that when outdoor coil pipe used temperature is more than 4 less than frosting temperature
DEG C when, after monitoring outdoor coil temperature 6 minutes duration in this state, illustrating that outdoor unit has greatly frosting can
Can, it can make difference D < 4, that is, outdoor coil pipe used temperature is made to be increased to specific temperature by the frequency of reduction compressor at this time
More than (i.e. frosting temperature subtract 4 DEG C), to inhibit outdoor unit frosting.Although it will be appreciated to those of skill in the art that the party
During inhibiting frosting, outdoor coil pipe used temperature allows to be less than frosting temperature formula, thus may lead to a small amount of frosting occur,
But since outdoor coil pipe used temperature less than frosting temperature is more than 4 DEG C of duration no more than 6 minutes, it equally can be with
Play the effect for inhibiting frosting.As long as also, due to which control outdoor coil temperature less than frosting temperature be more than 4 DEG C when
Between be no more than 6 minutes, therefore, the running frequency of compressor will not be reduced continually, to indoor heating amount influence compared with
It is small.In other words, on the one hand which plays the purpose for inhibiting outdoor unit frosting, on the other hand also reduces to indoor heating
The influence of amount.
It will be appreciated to those of skill in the art that after outdoor coil pipe used temperature is more than 4 DEG C less than frosting temperature, if
Duration is no more than 6 minutes, then illustrates that the frosting possibility of outdoor unit at this time is relatively low, and once outdoor coil pipe used temperature is less than
Frosting temperature is more than after 4 DEG C, and the duration is more than 6 minutes, then outdoor unit exist greatly frosting may, in this case
The running frequency for removing control compressor again has reduced reduction compressor operating frequency to the greatest extent under the premise of inhibiting outdoor unit frosting
The number of rate reduces the influence to indoor heating amount.
It should be noted that setting value among the above is illustrated using 4 as example, those skilled in the art can be with
Other rational setting values are neatly selected according to practical application, such as select the arbitrary value between 3-5 as setting value；Equally
Ground, above-mentioned duration T are illustrated using 6 minutes as example, and those skilled in the art can also be according to practical application
Neatly select other rational times, such as the random time between selection 5-7 minute, these are without departure from guarantor of the invention
Protect range.
As an example, the method for above-mentioned control compressor operating frequency can be realized by pid algorithm, or use other
The method of arbitrary known control compressor operating frequency, these are without departure from protection scope of the present invention.
It will be appreciated to those of skill in the art that frosting temperature can be preset according to the use environment of air conditioner,
It only needs to obtain outdoor coil temperature in use, and is compared with preset frosting temperature.Frosting temperature
Degree can also be directly detected by corresponding detection device, such as install corresponding detection device in outdoor unit, in real time or
Person interval preset time detects a frosting temperature.Frosting temperature can also be relatively wet by obtaining outdoor environment temperature and outdoor
It is calculated after degree.Specifically, the frosting temperature of air conditioner is calculated according to following formula：
T=-24.5+0.9T1+28.6 Φ (1)
In above-mentioned formula (1), T is frosting temperature, and T1 is outdoor environment temperature, and Φ is outside relative humidity.
In conclusion the present invention is in difference D >=setting value, and duration T >=setting time of difference D >=setting value
In the case of, by control compressor running frequency, make outdoor coil pipe used temperature less than frosting temperature be more than setting value (or
Other rational temperature) time be no more than T, to play the purpose for inhibiting outdoor unit frosting, while also reducing to interior
The influence of heating capacity improves the usage experience of user.
So far, it has been combined preferred embodiment shown in the drawings and describes technical scheme of the present invention, still, this field
Technical staff is it is easily understood that protection scope of the present invention is expressly not limited to these specific implementation modes.Without departing from this
Under the premise of the principle of invention, those skilled in the art can make the relevant technologies feature equivalent change or replacement, these
Technical solution after change or replacement is fallen within protection scope of the present invention.
