Wherein,f12(x)=a2*x2+ b2*x+c2, S22,
S12, d12 are matrix coefficient, and d22, a2, b2, c2 are three constant coefficient, u2For matrix [n, A, T2], G (T1, H)=a3*
T12+b3*T1+a4*H2+ b4*H+c3+c4, a3, b3, c3, a4, b4, c4 are the 4th constant coefficient, and n is the indoor fan
Motor speed, T2 are the temperature of the indoor heat exchanger, and T1 is the indoor environment temperature, and H is the indoor environment humidity, A
For the angle of the wind guide strip.
15. a kind of air conditioner, it is characterised in that including the power consumption amount detection device according to any one of claim 8-14
Put.
