Line frequency
The present invention makes outdoor coil pipe used temperature be higher than frosting temperature, or be less than by the running frequency of control compressor
Frosting temperature is no more than 3 DEG C (or other rational temperature), to play the purpose for inhibiting outdoor unit frosting, user is made to make
With the defrosting operation that need not be defrosted or be carried out during air conditioner heat-production seldom time, promote user uses body
It tests.
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 temperature is obtained；S120, calculating difference D=frostings temperature-outdoor coil temperature；S130, according to difference
Value D selectively controls the running frequency of compressor, so that difference D is less than setting value.Specifically, the method for the present invention is main
It is the running frequency by controlling compressor, and then controls outdoor coil temperature to realize the purpose for inhibiting frosting.
As an example, as difference D >=0, that is to say, that when outdoor coil pipe used temperature is less than frosting temperature, say
There are frosting possibility for bright outdoor unit, can make difference D < 0, that is, make outdoor coil pipe used by the frequency of reduction compressor at this time
Temperature is increased to frosting temperature or more, to inhibit outdoor unit frosting.Although it will be appreciated to those of skill in the art that the party
Formula reduces the running frequency of compressor, therefore can sacrifice part heating capacity, still, which during inhibiting frosting
Outdoor unit frosting can be effectively inhibited, to which defrosting number be reduced to a great extent, is reduced indoor caused by defrosting
The excessive problem of temperature fluctuation.
As another example, as difference D >=3, that is to say, that when outdoor coil pipe used temperature is more than less than frosting temperature
At 3 DEG C, illustrate that outdoor unit is possible in the presence of greatly frosting, can make difference D < 3 by the frequency of reduction compressor at this time,
That is, making outdoor coil pipe used temperature be increased to specific temperature (i.e. frosting temperature subtract 3 DEG C) or more, to inhibit outdoor unit frosting.This
Although field technology personnel are, it is understood which is during inhibiting frosting, outdoor coil pipe used temperature allows to be less than
Frosting temperature, thus may lead to a small amount of frosting occur, but it is no more than 3 since outdoor coil pipe used temperature is less than frosting temperature
DEG C, therefore, it can equally play the effect for inhibiting frosting.Also, since as long as which control outdoor coil temperature is less than knot
White temperature is no more than 3 DEG C, and therefore, the running frequency of compressor will not be lowered too much, thus influence to indoor heating amount 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 is illustrated as example it should be noted that setting value among the above is 0 and 3 respectively, people in the art
Member can also need neatly to select other rational setting values according to actual design, such as the arbitrary value between selection 0-3
As setting value, these are without departure from protection scope of the present invention.
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+28.6Φ (1)
In above-mentioned formula (1), T is frosting temperature, and T1 is outdoor environment temperature, and Φ is outside relative humidity.
In conclusion running frequency of the present invention by control compressor, makes outdoor coil pipe used temperature be higher than frosting temperature,
Either it is less than frosting temperature and is no more than 3 DEG C (or other rational temperature), to play the purpose for inhibiting outdoor unit frosting, makes
User need not defrost during using air conditioner heat-production or carry out seldom secondary defrosting operation, promote user's
Usage experience.
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.
