It please refers to shown in Fig. 6, a kind of control method of dual system refrigerator damping chamber, including spits lower process:
If the indoor damping preset value of damping chamber is H:
As damping preset value H < 45%, damping control method is as follows:
S00: after refrigerating chamber 2 requests refrigeration, refrigerator master control borad 6 controls dynamoelectric switching valve and switches so that refrigerating chamber capillary connects
Lead to and open refrigeration chamber blower 23 and compressor 3；
S01: it is pre- that refrigerator master control borad 6 judges whether the evaporator temperature that refrigeration evaporator temperature sensor 211 transmits is less than
If temperature A；If so, executing S04；If it is not, then executing S02；
S02: refrigerator master control borad 6 controls damping chamber electric flap 55 and is kept open；
S03: refrigerator master control borad 6 judges whether that current damping chamber humidity is greater than damping preset value H or temperature of refrigerating chamber reaches
To refrigerating chamber stopping point Toff；If so, executing S04；If it is not, then executing S02；
S04: refrigerator master control borad 6 controls damping chamber electric flap 55 and remains off；
In actual use: the humidity in damping chamber 5 is reduced rapidly to 20% or so and fresh-air fan 43 is whole not
It opens；After temperature of refrigerating chamber reaches refrigerating chamber stopping point Toff, damping chamber electric flap 55 is closed；Later in damping chamber 5
Because of sealing, enter without remaining moisture, slowly rises peak 50% or so, therefore medial humidity will remain in the water less than 45%
It is flat；
It please refers to shown in Fig. 7, as 45% < damping preset value H < 90%, damping control method is as follows:
A00: after refrigerating chamber 2 requests refrigeration, refrigerator master control borad 6 controls dynamoelectric switching valve and switches so that refrigerating chamber capillary connects
Lead to and open refrigeration chamber blower 23 and compressor 3, opens simultaneously damping chamber electric flap 55；
A01: refrigerator master control borad 6 judges whether current damping chamber humidity is greater than damping preset value H；If so, executing
A02；If it is not, then executing A03；
A02: damping chamber electric flap 55 is closed in the control of refrigerator master control borad 6；
S03: refrigerator master control borad 6 judges whether temperature of refrigerating chamber is less than refrigerating chamber stopping point Toff, if so, opening fresh air
Blower 43 simultaneously executes A01；If it is not, fresh-air fan 43 is then kept to close；
In actual use: since the opening of damping chamber electric flap 55 is synchronous with refrigeration chamber blower 23, steaming
The intracavitary damp and hot load of hair device is larger and refrigerator evaporator 21 overheats seriously, and bulk temperature is higher, causes in damping chamber 5
Dehumidifying effect decline；So when damping chamber 5 in humidity minimum point generally 40% or more；When damping chamber temperature and humidity passes
After sensor 56 monitors damping preset value H, then damping chamber electric flap 55 is closed；At this point, if temperature of refrigerating chamber is also not up to
Refrigerating chamber stopping point Toff, then damping chamber electric flap 55 remain off and meanwhile refrigeration chamber blower 23 and compression
Machine 3 works on to freeze for refrigerating chamber 2, and in the process, the air pressure in damping chamber 5 is less than refrigerator body external atmosphere pressure,
Because negative-pressure ward effect floats, a small amount of highly humid air enters in damping chamber 5 way ball float cavity 42；In damping chamber 5
Humidity rises；If temperature of refrigerating chamber reaches refrigerating chamber stopping point Toff, refrigeration chamber blower 23 and compressor 3 stop work
To make, negative pressure disappears in damping chamber 5, and fresh-air fan 43 is opened in the control of refrigerator master control borad 6, and way ball float cavity 42 is lifted,
After damping chamber Temperature Humidity Sensor 56 monitors damping preset value H, fresh-air fan 43 is closed, during this in damping chamber
Humidity passes through extraneous highly humid air humidification, and the interior rapid upper body of humidity, whole moisturizing humidity is between 45%~90%；
It please refers to shown in Fig. 8, as damping preset value H > 90%, damping control method is as follows:
B00: after refrigerating chamber 2 requests refrigeration, refrigerator master control borad 6 controls dynamoelectric switching valve and switches so that refrigerating chamber capillary connects
Lead to and open refrigeration chamber blower 23 and compressor 3, opens simultaneously fresh-air fan 43；
B01: refrigerator master control borad 6 judges whether temperature of refrigerating chamber is less than refrigerating chamber stopping point Toff, if so, executing B02；
If it is not, then executing B00；
B02: refrigerator master control borad 6 control dynamoelectric switching valve switch so that freezing chamber room capillary connection and compressor 3 close the border,
Meanwhile it opening damping chamber electric flap 55 and closing fresh-air fan 43；
B03: refrigerator master control borad 6 judges whether evaporator temperature is greater than preset temperature B；If so, it is electronic to close damping chamber
Air door 55 and refrigeration chamber blower 23；If it is not, then executing B02.
