The method increase refrigerating chamber humidity of fan delay, lacks specific aim, and time-consuming power-consuming, is unfavorable for energy-saving and emission-reduction, also gives full play to
The moisture-keeping functions of system.
The content of the invention
The present invention to overcome weak point that prior art is present there is provided a kind of moisturizing control method of wind cooling refrigerator and its
Using to can farthest improve the moistening effect of wind cooling refrigerator using the moisture-keeping functions of refrigerator inside system, and having
Reduce energy consumption, the effect of energy-saving and emission-reduction.
The present invention solves technical problem and adopted the following technical scheme that：
A kind of moisturizing control method of wind cooling refrigerator of the present invention, the wind cooling refrigerator includes refrigerating chamber；The refrigerating chamber leads to
Cross its evaporator and carry out independent cooling；One end of the evaporator is connected by independent capillary with compressor (7)；It is described to steam
The other end of hair device is provided with temperature sensor；And it is provided with fan and air-out in the cooling air duct towards the refrigerating chamber
Mouthful；It is characterized in, the moisturizing control method is carried out as follows：
Step 1, judge whether the refrigerating chamber freezes, if refrigeration, the compressor is run with rotating speed H, the fan
Run with rotating speed F1；Otherwise, step 2 is performed；
Step 2, the fan continue to run until that the temperature that the temperature sensor is collected reaches T1 with rotating speed F1
Untill；
Step 3, judge whether the compressor shuts down, if shutting down, perform step 4；Otherwise, the fan keeps stopping
Only；And return to step 3 is performed；
Step 4, the fan are run with rotating speed F2 intervals, until the temperature that the temperature sensor is collected reaches T2
Untill, F2 ＜ F1；T1 ＜ T2；Step 1 is returned again to perform.

Embodiment
In the present embodiment, a kind of moisturizing control method of wind cooling refrigerator is applied as depicted in figs. 1 and 2 with control
In the wind cooling refrigerator of system and refrigeration system, wind cooling refrigerator includes one or more compartments, is followed including with independent cooling
The refrigerating chamber 1 of loop system；Refrigerating chamber 1 carries out independent cooling by its evaporator 2；One end of evaporator 2 passes through independent capillary
Pipe is connected with frequency-changeable compressor 7；The other end of evaporator 2 is provided with temperature sensor 3；And in the refrigeration wind towards refrigerating chamber 1
Fan 4 and air outlet 5 are provided with road；Wherein, fan 4 played when refrigerating chamber 1 freezes forced convertion effect, by cold wind via
Cooling air duct is sent to refrigerating chamber 1, plays a part of reducing the temperature of refrigerating chamber 1；
The moisturizing control rule of wind cooling refrigerator is as follows：
When refrigerating chamber 1 freezes, now the temperature of evaporator 2 is higher, and relatively high rotating speed has weaker solidifying white ability, reflection
It is that the humidity that will not make refrigerating chamber 1 lowers rapidly in refrigerating chamber 1；The now operating of fan 4 and the rotating speed of compressor 7 have one
Individual optimum value, both further weaken the solidifying white ability of evaporator 2 with credit union；Therefore, frequency-changeable compressor frequency is suitably turned down, is made
Frequency-changeable compressor 7 is obtained to be run compared with slow-speed of revolution H, H scope is 900~2000RPM；So as to properly increase refrigerant evaporation temperature
Degree；Suitable rotation speed of the fan under the rotating speed is found simultaneously, the dehumidifying effect of evaporator is reduced to greatest extent；The wind that will coordinate with it
Fan 4 rotating speeds and be set to F1；F1 scope is 900~2500RPM；
When refrigerating chamber 1 stops freezing, fan 4 improves certain rotating speed when freezing relatively, and delay operation to evaporator 2 rises
To a certain temperature, the high humility humid air produced using evaporator 2 during now white water phase-state change sends refrigerating chamber back to via fan 4
1, it is rapidly achieved saturation state；Therefore, fan 4 is continued to be rotated to the sensor temperature rising T1 on evaporator 2 with F1 and stopped
Only；T1 scope is-1-3 DEG C；
When other compartments freeze, fan 4 keeps stopping；
When compressor 7 is shut down, during 2 temperature rapid increase of evaporator, the low speed start-stop of fan 4 alternating keeps high humility.
When the temperature of evaporator 2 reaches certain value, fan 4 is stopped, it is to avoid the temperature of refrigerating chamber 1 is affected greatly, therefore, wind
Fan 4 is interrupted with F2 to be opened, and rotation speed of the fan F2 and may be not equal to F1, usually F2 ＜ F1；Until the sensor temperature on evaporator 2
Degree rises to T2, T1 ＜ T2.
As shown in figure 3, specifically, the moisturizing control method of wind cooling refrigerator is to carry out as follows：
Step 1, judge whether refrigerating chamber 1 freezes, if refrigeration, compressor 7 is run with rotating speed H, fan 4 is transported with rotating speed F1
OK；Otherwise, step 2 is performed；
Step 2, fan 4 are untill rotating speed F1 continues to run until that the temperature that temperature sensor 3 is collected reaches T1；
Step 3, judge whether compressor 7 shuts down, if shutting down, perform step 4；Otherwise, fan 4 keeps stopping；And return
Step 3 is returned to perform；
Step 4, fan 4 are run with rotating speed F2 intervals, untill temperature that temperature sensor 3 is collected reaches T2；
Return again to step 1 to perform, gap periods are：Fan 4 is opened A minutes, is stopped B minutes；A scope is 0.5-3 minutes, and B scope is
3-15 minutes.
It is a kind of to use the wind cooling refrigerator that rule is controlled as described above, as shown in Figure 4 and Figure 5：
When refrigerating chamber 1 has refrigeration to ask, compressor 7 starts to run with relatively low rotating speed H, with this corresponding fan 4
Start to operate with optimum speed F.It can be seen that thus regular presence causes W2 and S2 fall to be significantly less than W1 and S1,
W2 and S2 minimum points are also of a relatively high, and P2 is relatively low with respect to P1, also favourable to saving energy consumption.
When refrigerating chamber 1 stops freezing, fan 4 still keeps rotation, now it can be seen that S2 rapid increases；Although S1
The relative humidity rapid increase of refrigerating chamber 1 can be made, but is usually, using the time as limitation, not account for the shape of evaporator 2
State；And the delay of the present invention is to reach temperature T1 as restrictive condition using sensor 3, the transition of evaporator 2 is taken into full account,
Take the temperature recovery of refrigerating chamber 1 into account, make S2 substantially arrive at peak, and be to the temperature of refrigerating chamber 1 using the waste cold of evaporator 2
Favourable.
When compressor 7 is stopped, general evaporator 2 has significantly temperature rise, and general defrosting water has been dripped,
Compartment humidity is close to saturation.Now relative humidity influence of the fan work on refrigerating chamber 1 is smaller, and holding is opened A minutes, is stopped B minutes
.General A is much smaller than B.But need to take 3 temperature into account simultaneously, it is impossible to be advisable more than T2.So just will not be to refrigerating chamber 1
Temperature causes big influence.This method is also a kind of natural defrost to evaporator 2.
