Embodiment
[0027] Example Figure 1 to Figure 3 As shown, assuming that the air volume of the blower is 350kg / h, the ambient temperature is 30°C, and the target evaporator temperature is 3°C, the calculations of K1 and K2 obtained according to the experimental results are as follows:
[0028] K1=0.79+0.09Teo+0.07Tamb+0.0037Teo 2 -0.037Teo*Tamb+0.017Tamb 2 =15.16,
[0029] K2=-273.5+23.62Teo+14.61Tamb-1.353Teo 2 +0.5139Tep*Tamb-0.5873Tamb 2 =-259.02,
[0030] Then the compressor feed-forward speed n=K1*x+K2=5200.98rpm.
[0031] In the general PI algorithm, the starting speed of the given compressor is a fixed value n=1000rpm. The comparison of the two algorithms is shown in the image 3 As shown, it can be seen that the algorithm system of the present invention is used to stabilize the system faster.
