When air conditioner is in low-temperature heating pattern, in order to increase the heating capacity of air conditioner to greatest extent, need to the greatest extent
The running frequency of the raising compressor of amount, and the running frequency of compressor is related to the electric current of compressor, running frequency is higher, pressure
The electric current of contracting machine is bigger, and in order to ensure compressor will not overload operation, the electric current of compressor should not exceed protective current, can
With understanding, air conditioner needs to ensure that its electric current is slightly less than guarantor while improving the running frequency of compressor to greatest extent
Protect electric current.Based on this, (predetermined current is slightly less than protective current namely predetermined current and protection electricity to air conditioner setting predetermined current
The difference of stream is smaller, and difference can be 0.5A), when the current flow of compressor be between predetermined current and protective current when,
Then judge that the electric current of compressor is slightly less than protective current, to improve the running frequency of compressor to greatest extent.
Air conditioner for the first time adjustment compressor running frequency after, air conditioner compare current flow, predetermined current and
Protective current, when current flow is less than predetermined current, at this point, the space that the running frequency of air conditioner is also improved, air conditioner
Preset running frequency increment value can be obtained, to increase the running frequency of compressor；When current flow is more than protective current, this
When, the running frequency that compressor is in the compressor of overwork namely the first adjustment is excessively high, needs the fortune for reducing compressor
Line frequency, air conditioner obtain running frequency decreasing value to reduce the running frequency of compressor.
In technical solution provided in this embodiment, air conditioner is according to current flow, predetermined current and protective current
Comparison result further adjusts the running frequency of compressor so that compressor is not under conditions of working overloadingly, to greatest extent
Its running frequency is improved, to improve the heating capacity of air conditioner to greatest extent.

The running frequency decreasing value of machine, and adjust according to the running frequency decreasing value running frequency of the compressor；
In the present embodiment, air conditioner is to increase gas to mend break air conditioner, which is equipped with flash vessel, and flash vessel is located at interior
Between heat exchanger (condenser) and outdoor heat exchanger (evaporator), the outlet of flash vessel and the refrigerant inlet of evaporator pass through pipeline
Connection, the outlet of flash vessel and the refrigerant exit of condenser are connected by pipeline.In a heating mode, compressor will be high for air conditioner
The gas of warm high pressure inputs condenser, which is condensed into liquid by condenser, after the refrigerant of liquid enters flash vessel, becomes
At gas, a part of gas is directly inputted into compressor from flash vessel gas supplementing opening, and it is further that a part is directly inputted into evaporator
Heat gas refrigerant.In the existing liquid of refrigerant that when the outlet temperature of flash vessel is less than gas supplementing opening temperature, flash vessel exports
There is gas, so that the heat that cryogenic gas is heated into high-temperature gas consuming by evaporator is less than liquid being heated into High Temperature Gas
The heat of body at this point, the heating efficiency of air conditioner can be reduced, namely reduces the heating capacity of air conditioner.In the fortune when compressor
When line frequency is excessively high, the transmission rate of refrigerant is fast so that partially liq refrigerant is not flashed device evaporation so that the outlet of flash vessel
Temperature is less than gas supplementing opening temperature, to cause the heating effect of air conditioner poor.Based on this, running frequency is being carried out to compressor
After adjustment, air conditioner obtain flash vessel outlet temperature and gas supplementing opening temperature, when outlet temperature be less than gas supplementing opening temperature when,
The running frequency decreasing value for obtaining compressor further, is less than tonifying Qi to reduce the running frequency of compressor in outlet temperature
When mouth temperature, its temperature gap is calculated, if temperature gap is more than preset difference value, judges gas outlet output liquid refrigerant, from
And it controls compressor and reduces running frequency.
In technical solution provided in this embodiment, air conditioner can determine whether to adjust after the running frequency of adjustment compressor
Running frequency whether can influence evaporation efficiency of the flash vessel to liquid coolant, to reasonably control compressor operation frequency
Rate, to ensure the heating effect of air conditioner.
