Further, present invention also offers a kind of refrigeration plant, it has storing compartment and rotary-type drying
Device 100, to be dehumidified using rotary-type 100 pairs of air entered in storing compartment of drier.Fig. 4 is
The schematic block diagram of refrigeration plant 200 according to an embodiment of the invention.Referring to Fig. 4, refrigeration plant
200 include the heat insulating box 201 with upper opening.Being internally formed for the heat insulating box 201 is used to preserve
The storing compartment 210 of food etc..According to storage temperature and purposes, the inside of heat insulating box 201 can be divided into
At least one storing compartment 210.In the illustrated embodiment, the inside of heat insulating box 201 is only divided into one
The individual storing compartment 210 as refrigerating chamber.Refrigeration plant 200, which may also include, to be respectively used to beat opening/closing storing
The door body 220 of compartment 210.
Outlet passageway 31 is dried to connect with the storing compartment 210 of refrigeration plant 200 by pipeline 50, and it is dry
Dry inlet channel 21 is connected with the external environment condition of refrigeration plant 200, with the temperature drop of storing compartment 210
When air pressure is reduced, ambient air outside has contained suction under gas pressure via dry inlet channel 21, one
The separation chamber 14 of wet stock 11 and dry outlet passageway 31 enter in storing compartment 210.
Well-known to those skilled in the art, refrigeration plant 200 can be with its compressor (not shown)
Periodicity start-stop, form periodic air-breathing, the phenomenon exhaled.I.e. during compressor is started shooting, storing
Temperature is reduced in compartment 210, and the atmospheric pressure in storing compartment 210 reduces, during compressor shutdown,
Temperature is raised in storing compartment 210, the atmospheric pressure increase in storing compartment 210.
Specifically, when refrigeration plant 200 is the freezing refrigerator that a volume is 300L, it is assumed that its external rings
The temperature in border is 25 DEG C (298K), and relative humidity is 75%RH, and atmospheric pressure is a standard atmospheric pressure
(i.e. 1.01325 × 105Pa).Pressed when the temperature of storing compartment 210 rises to -15 DEG C (258.13K)
Contracting machine is started shooting, the compressor shutdown when being down to -20 DEG C (253.13K) at a temperature of storing compartment 210.
It is assumed that storing compartment 210 is fully sealed, and when the temperature of storing compartment 210 is -15 DEG C, its interior air pressure
For a standard atmospheric pressure.According to boyle-boyle's law：P1 × T1=P2 × T2, it can be deduced that
P2=P1 × T1 ÷ T2, then Δ P=P2-P1=1.01325 × 105×258.13÷253.13-1.01325×105=2001Pa.
Wherein P1 is equal to a standard atmospheric pressure；T1 is equal to -15 DEG C；T2 is equal to -20 DEG C.I.e. when storing compartment 210
At a temperature of when being down to -20 DEG C, its interior air pressure increases 2001Pa.That is, storing compartment 210 is complete
When hermetically sealed, in a cooling cycle, the pressure difference inside and outside storing compartment 210 is 2001Pa to the maximum.But
Actually storing compartment 210 is not fully sealed, ambient air outside can in storing compartment 210 external pressure
Slowly leaked into inside storing compartment 210 at door seal under difference effect.According to 2 days (50 cooling cycles)
Maximum differential pressure is 30Pa inside and outside the data of interior actual measurement, storing compartment 210.
It is assumed that storing compartment 210 seals bad, inside and outside pressure is consistent, then according to Gay-Lussac's law：
V1 × T1=V2 × T2, it can be deduced that V2=V1 × T1 ÷ T2, then Δ V=V2-V1=V1 × T1 ÷ T2-V1=
(T1-T2) × V1 ÷ T2=(258.13-253.13) × 300 ÷ 253.13=5.9L.Wherein V1 is storing compartment
210 volumes, i.e., equal to 300L；T1 is equal to -15 DEG C；T2 is equal to -20 DEG C.I.e. in a cooling cycle,
Storing compartment 210 will suck 5.9L air, while the temperature recovery cycle excludes 5.9L air.This number
According to basically identical with actual measurement data, illustrate that the sealing effectiveness of door seal is relatively poor from another point of view.That is,
In a cooling cycle, storing compartment 210 substantially sucks the air (Δ for accounting for total measurement (volume) 2%
V ÷ V1=5.9 ÷ 300=2%).
Table look-up and learn, temperature is 25 DEG C, relative humidity is the exhausted of air that 75%RH, volume are 5.9L
It is 14.939g/kg to water content；Temperature is -18 DEG C, relative humidity is that 70%RH (when being -18 DEG C store up by temperature
Actual measured value in thing compartment 210), volume be 5.9L the absolute water content of air be 0.64g/kg；Temperature
Atmospheric density is 1.181kg/m when degree is 25 DEG C3；Atmospheric density is 1.385kg/m when temperature is -18 DEG C3；
The a cycle (+one temperature recovery cycle of i.e. one cooling cycle) of respiration can be considered as 0.5 hour,
It can then show that the water weight that daily (24 hours) storing compartment 210 is sucked and condensed is：
24÷0.5×5.9×10-3× (1.181 × 14.939-1.385 × 0.64)=4.75g.
The weight of the moisture leak into daily by door seal in storing compartment 210 is 4.75g.
, it is necessary to reach that the purpose that storing compartment 210 dehumidifies needs to meet 2 conditions knowable to calculating and measuring,
First, the outlet of the entrance of the drying inlet channel 21 of rotary-type drier 100 and dry outlet passageway 31
Between resistance should be much smaller than 30Pa, such storing compartment 210 is in air-breathing, and ambient air outside could be compared with
More via (i.e. ambient air outside is not substantially from door in rotary-type drier 100 inflow storing compartment 210
Leak at envelope in storing compartment 210), play a part of moisture absorption.Second, rotary-type drier 100 is needed extremely
The ability of 24 hours absorption 1.9g water is met less, i.e., rotary-type drier 100 at least adsorbs total inflow
40% (i.e. 4.75g × 40%), can just play preferable hygroscopic effect.
As it was previously stated, the drying inlet channel 21 of rotary-type drier 100 and the dry two ends of outlet passageway 31
Pressure difference be less than 3Pa, much smaller than the 30Pa required for door seal gas leakage, it is believed that between the storing of refrigeration plant
The gas that room 210 is sucked is substantially complete to be entered inside storing compartment 210 from rotary-type drier 100.I.e. in pressure
During contracting machine is started shooting, the surrounding air (air-flow i.e. to be dried) outside refrigeration plant 200 is essentially by runner
The drying inlet channel 21 of formula drier 100, the hygroscopic material 11 in moisture absorption position, dry outlet lead to
Road 31 is entered in storing compartment 210.
In addition, test indicate that, when the air that temperature is 25 DEG C, relative humidity is 75%RH flows through dry
After rotary-type drier 100,40%RH can be down in the relative humidity for drying the exit of outlet passageway 31 (right
To answer absolute water content be 7.879g/kg), it is assumed that in each cooling cycle, rotary-type drier 100 is in
The wettability power of the hygroscopic material of moisture absorption position is essentially identical, then can draw daily (i.e. 24 hours) runner
Formula drier 100 adsorb water weight be：
24÷0.5×5.9×10-3× 1.181 × (14.939-7.879)=2.355g.
That is, storing compartment 210 can be reduced daily using rotary-type drier 100 to suck always in cooling cycle
49.6% (i.e. 2.355 ÷ 4.75 × 100%) of water.
As can be seen here, the rotary-type drier 100 of the embodiment of the present invention is particularly suitable in refrigeration plant,
