Section method is that, when roller air-out humidity R1 is larger, rotation speed of fan A2 and Rolling motor revolving speed B2 are smaller, when roller air-out humidity
When R1 is smaller, rotation speed of fan A2 and Rolling motor revolving speed B2 are larger, specifically, as R1 >=70%, rotation speed of fan A2=
400rpm, Rolling motor revolving speed B2=40rpm；As 70% > R1 > 50%, rotation speed of fan A2=700rpm, Rolling motor revolving speed B2
=50rpm.Adjustment process to compressor frequency is, as R2-R1≤5%, S2=R1*100+T3-15, if the pressure detected
Contracting machine delivery temperature T4 < 85 DEG C, then compressor frequency presses calculated S2 continuous service, if the compressor exhaust temperature detected
T4>=85 DEG C, then compressor frequency detects T4 after running such as three minutes predetermined time according to S2-5 again, if the T4 detected<
85 DEG C, then compressor frequency presses S2-5 continuous service, otherwise continues to subtract 5 again for compressor frequency, until T4 < 85 of detection
℃.As 20%>=R2-R1>5%, S2=R1*100+T3-10, if compressor exhaust temperature T4<85 DEG C detected, are pressed
Contracting unit frequency presses calculated S2 continuous service, if compressor exhaust temperature T4 >=85 DEG C detected, compressor frequency are pressed
T4 is detected again after running such as three minutes predetermined time according to S2-5, if T4 < 85 DEG C detected, compressor frequency presses S2-5
Otherwise continuous service continues to subtract 5 again for compressor frequency, until T4 < 85 DEG C of detection.As R2-R1 > 20%, S2=R1*
100+T3-8, if compressor exhaust temperature T4 < 85 DEG C detected, compressor frequency presses calculated S2 continuous service, if
Compressor exhaust temperature T4 >=85 DEG C detected, then compressor frequency according to S2-5 run such as three minutes predetermined time after again
Secondary detection T4, if T4 < 85 DEG C detected, compressor frequency presses S2-5 continuous service, otherwise continues compressor frequency again
It is secondary to subtract 5, until T4 < 85 DEG C of detection.
In second drying stage, according to the roller leaving air temp T1 in the stage, roller inlet air temperature T2, roller air-out humidity
R1, roller enter the wind the delivery temperature T4 of humidity R2, the evaporating temperature T3 of heat pump system and/or compressor to the second drying stage
Rotation speed of fan A3, Rolling motor revolving speed B3 and/or compressor frequency are adjusted for S3, and specifically adjusting method is, works as roller
When air-out humidity R1 is larger, rotation speed of fan A3 and Rolling motor revolving speed B3 are smaller, and when roller air-out humidity R1 is smaller, blower turns
Fast A3 and Rolling motor revolving speed B3 are larger, specifically, as 50% >=R1 > 40%, rotation speed of fan A3=1100rpm, roller electricity
Machine revolving speed B3=55rpm；As 40% >=R1 > 30%, rotation speed of fan A3=1400rpm, Rolling motor revolving speed B3=60rpm.It is right
The adjustment process of compressor frequency is, as R2-R1 >=15%, S3=R1*100+T3+10, if the compressor air-discharging detected
Temperature T4<85 DEG C, then compressor frequency presses calculated S3 continuous service, if compressor exhaust temperature T4>=85 detected
DEG C, then compressor frequency detects T4 after running such as three minutes predetermined time according to S3-5 again, if T4 < 85 DEG C detected,
Then compressor frequency presses S3-5 continuous service, otherwise continues to subtract 5 again for compressor frequency, until T4 < 85 DEG C of detection.When
When 15%>R2-R1>=10%, S3=R1*100+T3+13, if compressor exhaust temperature T4<85 DEG C detected, compressor
Frequency presses calculated S3 continuous service, if compressor exhaust temperature T4 >=85 DEG C detected, compressor frequency is according to S3-
T4 is detected again after 5 such as three minutes predetermined times of operation, if T4 < 85 DEG C detected, compressor frequency is continued by S3-5
Operation, otherwise continues to subtract 5 again for compressor frequency, until T4 < 85 DEG C of detection.As R2-R1 < 10%, S3=R1*100+
T3+15, if compressor exhaust temperature T4 < 85 DEG C detected, compressor frequency presses calculated S3 continuous service, if detection
Compressor exhaust temperature T4 >=85 DEG C arrived, then compressor frequency is examined again after running such as three minutes predetermined time according to S3-5
T4 is surveyed, if T4 < 85 DEG C detected, compressor frequency presses S3-5 continuous service, otherwise continues again to subtract compressor frequency
5, until T4 < 85 DEG C of detection.
In third drying stage, according to the roller leaving air temp T1 in the stage, roller inlet air temperature T2, roller air-out humidity
R1, roller enter the wind the delivery temperature T4 of humidity R2, the evaporating temperature T3 of heat pump system and/or compressor to third drying stage
Rotation speed of fan A4, Rolling motor revolving speed B4 and/or compressor frequency are adjusted for S4, and specifically adjusting method is, works as roller
When air-out humidity R1 is larger, rotation speed of fan A4 and Rolling motor revolving speed B4 are smaller, and when roller air-out humidity R1 is smaller, blower turns
Fast A4 and Rolling motor revolving speed B4 are larger, specifically, as 30% >=R1 > 25%, rotation speed of fan A4=750rpm, Rolling motor
Revolving speed B4=65rpm；As 25% >=R1 > 20%, rotation speed of fan A4=1000rpm, Rolling motor revolving speed B4=75rpm.To pressure
The adjustment process of contracting unit frequency is, as R2-R1 >=10%, S4=R1*100+T3+10, if the compressor air-discharging temperature detected
Spend T4<85 DEG C, then compressor frequency presses calculated S4 continuous service, if compressor exhaust temperature T4>=85 DEG C detected,
Then compressor frequency detects T4 after running such as three minutes predetermined time according to S4-5 again, if T4 < 85 DEG C detected, are pressed
Contracting unit frequency presses S4-5 continuous service, otherwise continues to subtract 5 again for compressor frequency, until T4 < 85 DEG C of detection.When R2-R1 <
When 10%, S4=R1*100+T3+15, if compressor exhaust temperature T4 < 85 DEG C detected, compressor frequency is by calculating
S4 continuous service, if compressor exhaust temperature T4 >=85 DEG C detected, compressor frequency runs pre- timing according to S4-5
Between detect T4 again after such as three minutes, if T4 < 85 DEG C detected, compressor frequency press S4-5 continuous service, otherwise after
It is continuous that compressor frequency is subtracted 5 again, until T4 < 85 DEG C of detection.
