Only needing to supplement several grams of absolute humidity into refrigerating chamber 1 can be realized humidification to refrigerating chamber；
Assuming that in 5 DEG C of 1m3In environment, it to be intended to relative humidity 70%, it is only necessary to increase 5.09g vapor into the space
.Wind cooling refrigerator in its natural state, by door seal, turns the gaps such as beam without supplementing enough vapor in normal direction refrigerating chamber.Therefore
For this problem, switch to liquid heat absorption but the not changed principle of temperature using solid-state white on evaporator；When frost melts, ice
Case master control borad controls refrigeration fan and the humid air that defrost generates is blown into refrigerating chamber humidification；Utilize forced convection method, Xiang Lengzang
Interior is blown into highly humid air, shortens defrost heating time, so that system is opposite during entering defrost in single system wind cooling refrigerator
Humidity average value is promoted to 80% from 40% highest, significant increase refrigerating chamber preserving fruit and vegetable utilizing effect.

Value；If it is not, keeping A02 state；If so, executing A04；
Wherein, the default D value is that refrigerating chamber wants the top limit value of humidity kept.
