T4 is detected again after the 5 such as three minutes scheduled times of operation, if the T4 detected<85 DEG C, then compressor frequency is continued by S3-5
Operation, otherwise continues to subtract 5 again by compressor frequency, until the T4 of detection<85℃.Work as R2-R1<When 10%, S3=R1*100+
T3+15, if the compressor exhaust temperature T4 detected<85 DEG C, then compressor frequency is by the S3 continuous services calculated, if detection
Compressor exhaust temperature T4 >=85 DEG C arrived, then compressor frequency according to S3-5 run such as three minutes scheduled time after examine again
T4 is surveyed, if the T4 detected<85 DEG C, then compressor frequency press S3-5 continuous services, otherwise continue again to subtract compressor frequency
5, until the T4 of detection<85℃.
In 3rd drying stage, according to the roller leaving air temp T1, roller inlet air temperature T2, roller air-out humidity in the stage
R1, roller into wind moisture R2, the evaporating temperature T3 of heat pump system and/or compressor delivery temperature T4 to the 3rd drying stage
Rotation speed of fan A4, Rolling motor rotating 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 rotating speed B4 are smaller, and when roller air-out humidity R1 is smaller, wind turbine turns
Fast A4 and Rolling motor rotating speed B4 is larger, specifically, as 30% >=R1>When 25%, rotation speed of fan A4=750rpm, Rolling motor
Rotating speed B4=65rpm；As 25% >=R1>20%, rotation speed of fan A4=1000rpm, Rolling motor rotating speed B4=75rpm.To pressure
The adjusting 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 is by the S4 continuous services calculated, if compressor exhaust temperature T4 >=85 DEG C detected,
Then compressor frequency detects T4 again after running such as three minutes scheduled time according to S4-5, if the T4 detected<85 DEG C, then press
Contracting unit frequency presses S4-5 continuous services, otherwise continues to subtract 5 again by compressor frequency, until the T4 of detection<85℃.Work as R2-R1<
When 10%, S4=R1*100+T3+15, if the compressor exhaust temperature T4 detected<85 DEG C, then compressor frequency is by calculating
S4 continuous services, 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 the T4 detected<85 DEG C, then compressor frequency press S4-5 continuous services, otherwise after
It is continuous that compressor frequency is subtracted 5 again, until the T4 of detection<85℃.
It is further preferred that dryer carries out step S100 first before step S200 is carried out：Dryer enters drying
After pattern, the antifrost stage is carried out first, in this stage, rotation speed of fan rises to A1 by 0, and Rolling motor rotating speed is risen to by 0
B1, after the 5th scheduled time t5, compressor is opened and runs its frequency to S1.Wind turbine is opened first can be by air
Circulation is got up, and is then then turned on compressor, prevents heat pump system especially overheat of compressor from causing damage to system.
The scope of rotation speed of fan A1 therein is 450 to 500rpm, more preferably 500rpm, Rolling motor rotating speed B1

Further, in step S100, when detect heat pump system evaporating temperature be more than 0 DEG C when, explanation will not frosting,
Enter step 2OO.
It is further preferred that in step S500, when the clothes aridity in roller meets dry require, first by compressor
Shut down with Rolling motor, and after the 6th scheduled time t6, by fan parking, heat pump is taken away also for wind turbine is enable
Preheating in system, avoids the accumulation of heat from causing damage heat pump system.
The scope of 6th scheduled time t6 therein is 5 to 10min, more preferably 5min.
The compressor continuous working period is long, causes damage to compressor to avoid caused by detection parameters are not allowed, into
In one step preferred embodiment, when detecting that the continuous working period of compressor is more than the 7th scheduled time t7, drying is forced
Machine stops clothes drying process, when the scope of the 7th scheduled time t7 is 5 to 7 small, when being more preferably 6 small.Wherein, drying is forced
The step of machine stopping clothes drying process, is similar with foregoing automatic shutdown, first shuts down compressor and Rolling motor, and pass through the 6th
After scheduled time t6, by fan parking, also for enabling wind turbine to take away the preheating in heat pump system, the product of heat is avoided
Deposit and cause damage to heat pump system.
