Detailed description of the invention
In the present embodiment, a kind of moisturizing control method of wind cooling refrigerator be applied in as depicted in figs. 1 and 2 have in the wind cooling refrigerator of control system and refrigeration system, wind cooling refrigerator comprises one or more rooms, comprising the refrigerating chamber 1 with the independent cooling circulatory system; Refrigerating chamber 1 carries out independent cooling by its evaporimeter 2; One end of evaporimeter 2 is passed through independently capillary and is connected with frequency-changeable compressor 7; The other end of evaporimeter 2 is provided with temperature sensor 3; And fan 4 and air outlet 5 is provided with in the cooling air duct leading to refrigerating chamber 1; Wherein, fan 4 plays forced convertion effect when refrigerating chamber 1 freezes, and cold wind is delivered to refrigerating chamber 1 via cooling air duct, plays the effect reducing refrigerating chamber 1 temperature;
The moisturizing control law of wind cooling refrigerator is as follows:
When refrigerating chamber 1 freezes, now evaporimeter 2 temperature is higher, and relatively high rotating speed has more weak solidifying white ability, and being reflected in refrigerating chamber 1 li is to make the humidity of refrigerating chamber 1 lower rapidly; There is an optimum value in the now running of fan 4 and the rotating speed of compressor 7, both cooperations can weaken the solidifying white ability of evaporimeter 2 further; Therefore, suitably turn down frequency-changeable compressor frequency, frequency-changeable compressor 7 is run with comparatively slow-speed of revolution H, and the scope of H is 900 ~ 2000RPM; Thus suitably improve refrigerant evaporating temperature; Rotation speed of the fan suitable under simultaneously finding this rotating speed, reduces the dehumidifying effect of evaporimeter to greatest extent; Fan 4 rotating speed be mated is set to F1; The scope of F1 is 900 ~ 2500RPM;
When refrigerating chamber 1 stops refrigeration, fan 4 improves certain rotating speed when relatively freezing, time delay moves to evaporimeter 2 and rises to a certain temperature, utilize now white water phase-state change time evaporimeter 2 produce high humility humid air send refrigerating chamber 1 back to via fan 4, make its state that reaches capacity fast; Therefore, fan 4 continues to stop to the sensor temperature rising T1 on evaporimeter 2 with F1 rotation; The scope of T1 is-1-3 DEG C;
When freezing in other rooms, fan 4 keeps stopping;
When compressor 7 is shut down, when evaporimeter 2 temperature rises fast, fan 4 low speed start-stop alternately, makes high humility keep.When evaporimeter 2 temperature reaches certain value, fan 4 quits work, and avoids affecting greatly refrigerating chamber 1 temperature, therefore, fan 4 with F2 be interrupted open, rotation speed of the fan F2 may and be not equal to F1, be generally F2 < F1; Until the sensor temperature on evaporimeter 2 rises to T2, T1 < T2.
As shown in Figure 3, specifically, the moisturizing control method of wind cooling refrigerator is carried out as follows:
Step 1, judge whether refrigerating chamber 1 freezes, if refrigeration, then compressor 7 runs with rotating speed H, and fan 4 runs with rotating speed F1; Otherwise, perform step 2;
Step 2, fan 4 continue to run, until the temperature that temperature sensor 3 collects reaches T1 with rotating speed F1;
Step 3, judge whether compressor 7 shuts down, if shut down, then perform step 4; Otherwise fan 4 keeps stopping; And return step 3 and perform;
Step 4, fan 4 run, until the temperature that temperature sensor 3 collects reaches T2 with rotating speed F2 interval; Return step 1 again to perform, gap periods is: A minute left by fan 4, stops B minute; The scope of A is 0.5-3 minutes, and the scope of B is 3-15 minute.
Adopt a wind cooling refrigerator for as above control law, as shown in Figure 4 and Figure 5:
When refrigerating chamber 1 has refrigeration request, compressor 7 starts to run with relatively low rotating speed H, starts to operate with optimum speed F with this corresponding fan 4.Can see that the existence of rule thus causes the fall of W2 and S2 to be significantly less than W1 and S1, W2 and S2 minimum point is also relatively high, and P2 is lower relative to P1, also favourable to saving energy consumption.
When refrigerating chamber 1 stops refrigeration, fan 4 still keeps rotating, and now can see that S2 rises fast; Although S1 also can make the relative humidity of refrigerating chamber 1 rise fast, be generally restriction with time, do not consider the state of evaporimeter 2; And time delay of the present invention reaches temperature T1 for restrictive condition with sensor 3, take into full account the transition of evaporimeter 2, take the temperature recovery of refrigerating chamber 1 into account, make S2 fully arrive peak, and the remaining cold temperature to refrigerating chamber 1 utilizing evaporimeter 2 is favourable.
When compressor 7 quits work, general evaporimeter 2 has significantly temperature rise, and general defrosting water drips, and a room humidity is close to saturated.The now relative humidity impact of fan work on refrigerating chamber 1 is less, keeps opening A minute, stops B minute.General A is much smaller than B.But need the temperature taking 3 into account simultaneously, can not be advisable more than T2.So just can not cause large impact to the temperature of refrigerating chamber 1.The method is also a kind of natural defrost to evaporimeter 2.
