Arbitrary temperature value, to ensure fluid liquid by cooling to subzero temperature with the air heat-exchange in refrigerator storing compartment
After will not freeze and will not solidify in other words.This fluid liquid can be inorganic solution, such as calcium chloride brine,
Chlorination lithium salt solution or other saline solution etc..Generally, such fluid liquid has following characteristic：1st, low
When warm, wettability power is big, and that is, the steam partial pressure on fluid liquid surface is low；2nd, during high temperature, wettability power subtracts
Little, that is, the steam partial pressure on fluid liquid surface is big.That is, when the temperature of fluid liquid is relatively low,
Part moisture (vapor) in the adsorbable dissolved air in other words with during air contact, thus realize right
Air dewetting；When the temperature of fluid liquid is higher, may be dissolved in its interior part moisture during air contact
In the air (i.e. evaporation forms vapor, is carried away by air).
First passage 10 is used for being delivered to the air of refrigerator space outerpace indoor between the storing of refrigerator.I.e.
The import of one passage 10 is communicated with refrigerator space outerpace, and its outlet is communicated with refrigerator storing compartment.Work as refrigerator
Compressor start when, between storing indoor temperature reduce thus in it air pressure reduce (i.e. refrigerator is inside
Air-breathing), the air of refrigerator space outerpace leaks into interior between storing by the first passage 10 of dehumidification module
Portion.The partial air entering in first passage 10 will be along the surface of the first hygroscopic piece 11 to first passage 10
