Embodiment 1
[0071] An example of a multi-stage temperature control curve and temperature control parameter configuration interface is Figure 8 As shown, the multi-stage temperature control curve in this embodiment is a 10-stage heating curve. The control device 500 controls the double-cycle hot air drying system to realize intelligent and fully automatic operation by configuring the set temperature and temperature stabilization time of each time period. No manual manipulation is required.
[0072] according to Figure 6 As shown in the embodiment of the control method of the heat pump double-circulation hot air drying system of the present invention, the step S400 includes the following control operations:
[0073] S420: If the set temperature is Figure 8 For the 1st to 5th segments of the 10-segment heating curve shown, the set air outlet temperatures are 20°C, 25°C, 30°C, 35°C and 40°C respectively.
[0074] S440: If the set temperature is Figure 8 In the 6th and 7th segments of th...
Embodiment 2
[0078] The size of a tobacco drying room is: 8×2.8×2.2m, and the amount of tobacco leaves to be dried at one time is 350 rods, each rod is 30kg of tobacco leaves, totaling 10500kg. The variable-frequency variable-capacity heat pump hot air drying system is composed of a 6-hp fixed-frequency compressor 1-1 and a 6-hp variable-frequency compressor 1-2 connected in parallel. The maximum heating capacity is 50kW. The variable-frequency and variable-capacity connection structure of the unit is as follows: Figure 4 shown. For the temperature control curve of flue-cured tobacco process, see Figure 9 In the multi-stage drying process diagram shown, the heat consumption in each period is as follows Figure 10 shown. The control device 500 selects an appropriate operation mode through comparative analysis to achieve maximum operation efficiency.
[0079] according to Figure 7 As shown in the embodiment of the control method of the variable frequency and variable capacity heat pump...
