By taking heating as an example, the first subinterval be (b0, b2], the second subinterval be (b2, b1], any temperature in the first subinterval
Angle value is less than the second subinterval.When outdoor temperature is in the first subinterval, under temperature model, controller 11 is by compressor 23
Highest frequency, increase preset value on the basis of the highest frequency of normal mode, preset value can be 4-9Hz.In outdoor temp
When degree is in the second subinterval, under temperature model, controller 11 sets compressor for the highest frequency of compressor 23 and runs
The preset ratio of upper frequency limit, which is 0.7-0.9, in this proportional region, the highest frequency of compressor 23 according to
It is old higher than the highest frequency of normal mode.
In the case that normal mode freezes, outdoor temperature is lower, and 23 frequency of compressor is lower, may transport much smaller than compressor
The line frequency upper limit, therefore after being switched to temperature model, by increasing preset value, compressor frequency is increased to higher level
And it is more difficult no more than the compressor operating frequency upper limit, it uses directly be set as pressing by the highest frequency of compressor 23 at this time
