Temperature, the control freezing fan 22 of controller 10 are opened cold to send in freezing chamber 2.Since auxiliary humidification evaporator 14 is refrigerating evaporator
21 end pipelines, auxiliary humidification 14 temperature of evaporator also declines to a great extent at this time, but due to being located in 1 foaming layer of prefecture compartment, specially
The reasons such as the internal temperature of section room 1 is higher, therefore its average surface temperature generally will not be too low, condensation and auxiliary humidification evaporator
The white water on 14 surfaces is just suitably for air humidification in prefecture compartment 1.
As shown in figure 4, a kind of humidity control method in refrigerator prefecture, includes the following steps:
Step 1: passing through environment temperature and the default temperature in refrigerator prefecture compartment 1 for incuding environment temperature sensor 101
Degree is compared, and when environment temperature is higher than preset temperature, controller 10 determines that prefecture compartment 1 needs to be implemented refrigeration movement, this
When decreasing temperature and increasing humidity structure start to work, specific works method is:
Frequency-changeable compressor 3 beginning run with relatively low revolving speed H sent to prefecture compartment 1 it is cold, switching valve 7 be tunneled to prefecture hair
8 position of tubule, the evaporating temperature of prefecture evaporator 11 is higher under this revolving speed, and prefecture fan 12 cooperates frequency-changeable compressor 3 to close
Suitable revolving speed F1 operation, freezes while being unlikely to cause humidity in prefecture compartment 1 too low (less than 50%)；When warm in prefecture compartment 1
Degree reaches break point, and frequency-changeable compressor 3 goes to the refrigeration of freezing chamber 2 or shuts down, and evaporator 11 temperature in prefecture rises at this time, remains special
Area's fan 12, which proceeds to prefecture evaporator sensor 13 and rises to T1 temperature, just to stop rotating, by high temperature and humidity steam size
It returns to prefecture compartment 1；Absolute humidity reaches saturation state and maintains high humility 95% automatically in prefecture compartment 1 after stopping,
When this arrangement works, relative humidity average value is 95% in 1；
Step 2: passing through environment temperature and the default temperature in refrigerator prefecture compartment 1 for incuding environment temperature sensor 101
Degree is compared, and when environment temperature is lower than preset temperature, controller 10 determines that prefecture compartment 1 needs to be implemented heating movement, this
Shi Shengwen humidification structure is started to work, and specific works method is:
Since temperature is generally -16 hereinafter, still maintain refrigeration work state in freezing chamber 2, prefecture compensating heater 112
It opens, while refrigerating evaporator 21 works so that humidification 14 temperature of evaporator is assisted to decrease, the control auxiliary of controller 10 increases
15 work of wet wind fan, wait assist the temperature on humidification evaporator 14 to open when being down to T2, storage is wet, and air is via auxiliary in prefecture compartment 1
Humidification fan housing air outlet 171 and auxiliary humidification fan housing return air inlet 172 is helped to form circulation constantly by auxiliary humidification 14 table of evaporator
Face is trapped to form white water, and assists humidification fan 15 to continue rotation to auxiliary evaporator when freezing chamber 2 stops freezing and sense
Device 16 rises to T3, and white aqueous fusion is melted into highly humid air in auxiliary humidification fan housing 17 at this time, is returned to prefecture compartment 1, is humidified
It completes, this nested structure is able to maintain that relative humidity average value in prefecture compartment 1 85% or more；
Step 3: passing through environment temperature and the default temperature in refrigerator prefecture compartment 1 for incuding environment temperature sensor 101
Degree is compared, and when environment temperature is equal with preset temperature, controller determines to remain unchanged in prefecture compartment 1.
Wherein, the tachometer value of H is 1200RPM, and the tachometer value of F1 is 2000RPM.
Wherein, the value of T1 is -2 DEG C.
Wherein, the value of T2 is -10 DEG C.
Wherein, the value of T3 is 2 DEG C.
