For example, air conditioner is in cooling mode, outdoor unit has learnt that two indoor units are in open state by communication, Ability is respectively nominally 36,28, then indoor unit is always nominally 64；The environment temperature of environment is respectively where the indoor unit of start 29th, 31, then the average value of the environment temperature of environment where indoor unit is 30；k₁Take 0.75, X₁Take 27, then first frequency is mended Repay value F_t1=0.75* (30-27)=2 (result of calculation round numbers).

Step S322, the environment temperature of environment according to where the outdoor unit, the second frequency for calculating the compressor are mended Repay value；

In the present embodiment, second frequency offset can be solved according to the following formula：

When the current operational mode of air conditioner is refrigeration mode, F_t2=k₃* (T₂-X₃), in the current operation of air conditioner When pattern is heating mode, F_t2=k₄* (X₄-T₂)。

Wherein, F_t2For the second frequency offset of compressor；k₃、k₄For penalty coefficient, X₃、X₄For constant, by substantial amounts of Experiment obtains；T₂The environment temperature of environment where outdoor unit.

For example, air conditioner is in cooling mode, the environment temperature of environment where outdoor unit is 35, k₃Take 0.14, X₃Take 35, So second frequency offset F_t2=0 (result of calculation round numbers).

Step S323, compensated according to total nominal, the described first frequency offset of the indoor unit and the second frequency Either the indoor unit is total nominal and the first frequency offset or indoor unit is total nominal and the described second frequency for value Rate offset calculates the frequency threshold of the compressor.

In the present embodiment, the purpose for calculating the first temperature compensation value and second temperature offset is to realize to air conditioner more Add and accurately control, and in the case where not influencing air conditioner reliability, expand the range of operation of air conditioner, realize air conditioner system Cold or heat-production functions maximizations.Therefore can merely with the first temperature compensation value or merely with second temperature offset, Or the first temperature compensation value and second temperature offset are utilized, calculate the frequency threshold of compressor.

Specifically, the frequency threshold of compressor is solved by the following formula：

F_max=K*N+F_t1+F_t2+b

Wherein, F_maxFor the frequency threshold of compressor；N is always nominal for indoor unit；F_t1For first frequency offset, F_t2For Two frequency compensation values, first frequency offset and second frequency offset can be calculated according to temperature information；K is equal with b It is by largely testing definite constant, K can be that 0.8, b can be 8.

For example indoor unit is always nominally 64, first frequency offset is 2, and second frequency offset is 0, then compressor Frequency threshold is 0.8*64+2+0+8=61.
