Air conditioner under heating operating mode when working, outdoor unit heat absorption, indoor unit heat dissipation, since outdoor environment temperature is low
Usually below ten degree, when outdoor unit also needs to absorb heat, evaporator body temperature can drop to less than 0 degree, the moisture of surrounding
When refrigeration (similar dehumidifying) quickly will condense into frost.After evaporimeter frosting, the relatively low refrigerant of temperature passes through air conditioner external
When cannot evaporate, heat can not be absorbed, no heat brings interior into, and air conditioner is unable to reach the effect of heating.
Therefore when temperature, time reach established standards, air conditioner can control indoor unit in air-conditioning system to inhale automatically into defrosting
Heat, outdoor unit heat dissipation, to melt the frost condensed on evaporator, improves the heating effect of air-conditioning.Because under air conditioner defrosting mode,
It is the heating for being unfavorable for indoor environment to indoor heat absorption, so after air conditioner enters defrosting mode, acquisition is default initially to remove

Step S41 when the pressure at expulsion is greater than or equal to default defrosting pressure, obtains default defrosting frequency, by institute
Air conditioner defrosting frequency is stated to adjust to default defrosting frequency.
The default defrosting frequency under air conditioner defrosting mode is set by existing experiment or experience, default defrosting frequency is less than
The initial defrosting frequency of above-mentioned air conditioner, in the case where this presets defrosting mode, enables to the pressure at expulsion of air conditioner to maintain one
In the range of a safe pressure, effectively prevent defrosting process increase pressure at expulsion and cause the air conditioner lost of life and be unable to reach
The generation of the harm such as normal work.When detecting that pressure at expulsion is greater than or equal to default defrosting pressure, air conditioner is current
Defrosting frequency is adjusted to default defrosting frequency, to ensure the safety of air conditioner.
Step S42, after the default defrosting frequency defrosting prefixed time interval, the row of air conditioner described in timing acquisition
Atmospheric pressure.
Step S43, when the pressure at expulsion is greater than or equal to default defrosting pressure, the frequency that will currently defrost is adjusted to pre-
If next grade of defrosting frequency in the group of frequencies that defrosts.
According to default defrosting frequency defrosting a period of time, then the pressure at expulsion of air conditioner is obtained, examined using default defrosting
During frequency defrosting, whether the pressure at expulsion of compressor on the premise of air conditioner quickly defrosting, protects in default defrosting pressure
Hinder the safety of air conditioner.
Defrosting group of frequencies is preset, several defrosting frequencies are included in group, the frequency that will defrost is according to frequency size number, frequency
Bigger gear number is smaller, and gear number is the gradual increased integer by 1, wherein, above-mentioned default defrosting frequency is pre-
If frequency maximum in the group of frequencies that defrosts, therefore gear is also near preceding.For example, the number of frequency maximum is in default defrosting group of frequencies
1 grade, secondary big number is 2 grades, and so on.To meet the defrosting function of air conditioner, energy is only set in default defrosting group of frequencies
Enough default defrosting frequencies effectively to defrost, that is, the minimum defrosting frequency preset in defrosting group of frequencies can also meet basic defrosting need
It asks.
It is higher in outdoor unit frosting degree, it, may be currently to defrost what frequency defrosted when the difficulty that causes to defrost is larger
The pressure at expulsion of air conditioner is increased beyond default defrosting pressure in the process, to ensure the safety of air conditioner, in currently defrosting frequency
During higher than minimum defrosting frequency in above-mentioned default defrosting group of frequencies, current defrosting frequency is reduced to default defrosting group of frequencies
In next grade defrosting frequency, continue to raise with the pressure at expulsion for preventing air conditioner.
In addition, if when currently defrosting frequency is the minimum defrosting frequency in above-mentioned default defrosting group of frequencies, not so that removing
Frost is normally carried out, and current defrosting frequency is maintained to defrost.
In the present embodiment when detecting that pressure at expulsion is greater than or equal to default defrosting pressure, by air conditioner removing currently
White frequency is adjusted to default defrosting frequency, according to the default defrosting frequency defrosting a period of time, to reach defrost effect, defrosting one
The pressure at expulsion of air conditioner described in timing acquisition again after the section time.Defrosting pressure is preset detecting that pressure at expulsion is greater than or equal to
When, current defrosting frequency is adjusted to next grade of defrosting frequency in default defrosting group of frequencies, until the current defrosting of air conditioner
When frequency is down to minimum defrosting frequency in default defrosting group of frequencies, the frequency that defrosts is not being reduced, ensureing being normally carried out for defrosting.It adopts
