52 DEG C, T2=58 DEG C.
In above-mentioned steps, when being run because of two blower fans, two evaporators can obtain good radiating.According to evaporation
The coil temperature of device is modified to compressor frequency, air-conditioning is both met heating needs, and can avoids coolant circulating system
There is running overload.
Step S509, when only one blower fan is opened, the value of temperature range and Ta, Tb, Tc according to residing for Ta-Tb determines
The running frequency of compressor.Specifically, frequency correction factor b=b (Ta-Tb) is calculated according to temperature difference Ta-Tb, controls compressor
Running frequency f=b*f (Ta, Tb, Tc), b ＜ 1 in formula.
Specifically, b value can be determined according to the temperature range residing for Ta-Tb.As Ta-Tb ＜ T3, b=b1；Work as T3
During≤Ta-Tb≤T4, b=b2；As Ta-Tb ＞ T4, b=b3, b1 ＜ b2 ＜ b3 in formula.In certain embodiments, T3=7
DEG C, T4=13 DEG C, b1=0.5, b2=0.8, b3=0.9.
In above-described embodiment, during only one fan operation, to avoid not changed by the evaporator section that the wind of the blower fan covers
Heat is unfavorable to cause hypertonia, and above-described embodiment reduces the running frequency of compressor, avoid compressor overload by making b ＜ 1
Operation.
