Description
Technical field
The present invention relates to a kind of control method and refrigerator of dry room, belong to household appliance technical field.
Background technology
Humidity generally refers to air humidity in meteorology, is the content of water vapor in air, and does not comprise liquid or solid-state water.Not steam-laden air is called as dry air.Because vapor in the atmosphere can account for 0% to 4% of volume of air, generally refer to the composition that these compositions are shared in dry air when the composition listing various gas in air.
" absolute humidity " refers to the quality of the steam contained in the air of certain volume, and generally its unit is g/cubic metre.Absolute humidity be most high humility under saturation state to greatest extent.
" relative humidity " (RH) is the ratio between absolute humidity and most high humility, and how high the saturation degree of its value display steam have.Relative humidity be 100% air be saturated air.Relative humidity be 50% air contain the steam of the half of the saturation point reaching synthermal air.Relative humidity generally to be condensed water outlet or ice more than the steam in the air of 100%.Along with the rising of temperature, the steam vapour amount that can dissolve in air increases, and the absolute humidity values of air increases.When the rh value of air is more than 100%, the steam in air will condense out, and can be used for cool-down dehumidification; Temperature raised, relative humidity will reduce again, and can be used for reaching dry object.
The drying of food, main relevant with relative humidity.Relative humidity is low, and the possibility that food obtains moisture is little.
The storeroom developing low relative humidity in refrigerator can be used for storing various dry or needing dry food (as tealeaves, dry fruit etc.).The relative humidity of dried foods to storage ambient is more responsive, usually needs the relative humidity that one is lower, and can be constant within the scope of a smaller relative humidity variations, otherwise, very easily cause the rotten of food or affect quality.
Between tradition reduces, the mode of room relative humidity is the principle adopting cool-down dehumidification, namely the cooling function of evaporimeter is utilized, by an indoor air by the abundant cooling down of evaporimeter, precipitation steam dehumidifies, obtain the air that absolute moisture content is lower, then and an indoor absolute moisture content higher air displacement (between being about to indoor absolute moisture content higher air drive out of, between indoor air absolute moisture content be reduced), heat up under the heat effect of then environment around, thus realize obtaining lower relative humidity, reach dry object.
But there are the following problems in current dry room have to be solved:
1, at the end of a kind of refrigeration cycle; the compressor shutdown initial stage is to the air-supply of dry room; the reason causing dry room relative humidity to increase has: behind (1), compressor shutdown; refrigeration system initiation pressure balances; on high-tension side warm refrigerant flows into low-pressure side; the temperature of evaporimeter can rising gradually, and cause the frost on evaporimeter can accelerate distillation, near evaporimeter, the relative humidity of air can be higher.(2) when, having defrost, the frost of evaporimeter can melt, rising due to temperature accelerates defrost evaporation of water, near evaporimeter, the relative humidity of air is higher, and in addition, a part of water can adhere on an evaporator, cause when upper once compressor start, under the drive of blower fan, send in dry room, humidification is carried out to dry room.(3), the compressor shutdown initial stage; the temperature that evaporimeter compares room and environment between surrounding is in lower state of temperature; be subject to the leakage heat affecting from room between higher temperature and environment, the temperature of evaporimeter and surrounding air thereof can raise gradually, causes the frost of evaporimeter to melt or to distil.Cause being reflected as in whole dehumidification process: when compressor is started shooting at every turn, along with giving the air-supply of dry room, the relative humidity of dry indoor can produce the crest that a larger relative humidity increases.
2, when compressor is just started shooting, because evaporator surface temperature is higher, air themperature near evaporimeter is not also cooled to the temperature enough separating out moisture, and (that is:, when humid air temperature reaches dew-point temperature, namely reach capacity state namely not reach the dew-point temperature of air.Have moisture when continuing cooling to separate out, dehumidifying object can be reached; Otherwise when humid air temperature is more than dew-point temperature, the moisture in humid air can not be separated out, and does not reach the object of dehumidifying).

Detailed description of the invention
Refer to Fig. 1, the refrigerator in one embodiment of the invention has refrigerator room 1, freezing compartment and cooling cycle system.Described refrigerator room 1 and freezing compartment are referred to as refrigeration compartment.Be provided with dry room 2 in described refrigerator room 1, the normal temperature in described refrigerator room 1 is 0 ~ 10 DEG C, generally at 6 ~ 8 DEG C; Temperature in described dry room 2 lower than the temperature in refrigerator room 1, generally at 3 ~ 5 DEG C.Described cooling cycle system comprises condenser, compressor, evaporimeter 3 and capillary, and described cooling cycle system is identical with existing cooling cycle system, therefore does not elaborate.Described evaporimeter 3 is arranged in cooling chamber 4, the air inlet 21 of described dry room 2 is communicated with by cold passage 5 with cooling chamber 4, refrigerator room 1, and described cold passage 5 comprises the major trunk roads 51 that are connected with cooling chamber 4 and connects major trunk roads 51 and the air inlet 21 of dry room 2, the arterial highway 53,52, second point, first point of arterial highway of refrigerator room 1 respectively.The side of described evaporimeter 3 is provided with the blower fan 6 be introduced into by the air in cooling chamber 4 in refrigerator room 1 and dry room 2, and in the present embodiment, described blower fan 6 is arranged in cooling chamber 4.The side of described first point of arterial highway 52 is provided with the first air door 71 to realize opening or closing of first point of arterial highway 52, and the side of described second point of arterial highway 53 is provided with the second air door 72 to realize opening or closing of second point of arterial highway 53.Opening or closing of first point of arterial highway 52 and second point of arterial highway 53 is controlled by the first air door 71 and the second air door 72, thus the air displacement in the air displacement realized respectively in dry room 2 and refrigerator room 1.At this, described first point of arterial highway 52 can be described as the first cold passage, and described second point of arterial highway 53 can be described as the second cold passage.Be provided with respectively in order to detect the first temperature inductor and first humidity sensor of temperature in dry room 2 and relative humidity in described dry room 2, be provided with in described cooling chamber 4 respectively in order to detect the second temperature inductor and second humidity sensor of temperature in cooling chamber 4 and relative humidity, in described refrigerator, be provided with controller.In the present embodiment, described first point of arterial highway 52 and second point of arterial highway 53 adopt air door to realize opening or closing, and in other embodiments, other modes can also be adopted to realize.
The control method of the dry room 2 of described refrigerator is the start-up time that the opening time of described first point of arterial highway 52 or blower fan 6 are later than the compressor in refrigerator start-up time.
The opening time of described first point of arterial highway 52 is later than the start-up time of blower fan 6.The start-up time of described first point of arterial highway 52 or blower fan 6 is determined by following three kinds of modes, and wherein, two kinds of modes below can also reach the object of dehumidifying accurately.
In refrigerator, presetting the start-up time of first point of arterial highway 52 and blower fan 6, when after compressor start, starting after first point of arterial highway 52 and blower fan 6 arrive Preset Time, the time of this Preset Time for obtaining after test of many times.
Because the relative humidity in dry room 2 needs to remain on lower numerical value (lower than refrigerator room 1), so, the air sent in dry room 2 needs dehumidifying, the criterion reaching dehumidifying object is: the absolute humidity of absolute humidity lower than air in dry room 2 sending into the air at the air intake vent place of dry room 2, and due to the air in dry room 2 be provided by cooling chamber 4, so the start-up time of first point of arterial highway 52 or blower fan 6 is determined to determine in the following way:
S1: obtain the absolute humidity ρ 1 in dry room 2, obtains the absolute humidity ρ 2 in cooling chamber 4;
S2: after absolute humidity ρ 1 is higher than absolute humidity ρ 2, described first point of arterial highway 52 is opened or blower fan 6 starts.What being opened for of this first point of arterial highway 52 controlled the first air door 71 by controller opens realization.
The specific implementation of described S1 step is as follows: described controller receive and process described first temperature inductor detect the temperature that obtains and the first humidity sensor detect the relative humidity that obtains to obtain absolute humidity ρ 1, controller receive and process the second temperature inductor detect the temperature that obtains and the second humidity sensor detect the relative humidity that obtains to obtain absolute humidity ρ 2.
When the relative humidity in described cooling chamber 4 is 100%, namely, when evaporimeter 3 having had condensation produce, the specific implementation of described S1 step can also be as follows: described controller receive and process described first temperature inductor detect the temperature that obtains and the first humidity sensor detect the relative humidity that obtains to obtain absolute humidity ρ 1, controller receives and processes temperature that the second temperature inductor obtains to obtain absolute humidity ρ 2.Now, relative humidity is obtained without the need to adopting the second humidity sensor to detect.
It should be noted that at this, when first point of arterial highway 52 of dry room 2 is not opened, the air in cooling chamber 4 will be sent to other indoor, as in refrigerator room 1 or freezing compartment.
Because absolute humidity values is not easily measured in refrigerator, so when specifically controlling, temperature can be adopted as standard, now, the start-up time of first point of arterial highway 52 or blower fan 6 is determined to determine in the following way:
S1: obtain the dew-point temperature in dry room 2, obtain the temperature in cooling chamber 4, temperature in dew-point temperature in dry room 2 and cooling chamber 4 obtains in the following way: controller receives and processes the temperature detected by the first temperature inductor in dry room 2 and the relative humidity detected by the first humidity sensor to obtain dew-point temperature, the temperature of cooling chamber 4 is detected by the second temperature inductor in cooling chamber 4 and obtains, described dew-point temperature is learnt by humid air psychrometric chart preset in controller inquiry, specifically learn by calculating and inquire about after the temperature of controller detected by the first received temperature inductor and the relative humidity detected by humidity sensor,
S2: after the temperature in cooling chamber 4 is lower than the dew-point temperature in dry room 2, first point of arterial highway 52 is opened or blower fan 6 starts.What being opened for of this first point of arterial highway 52 controlled the first air door 71 by controller opens realization.
Suppose: when compressor is opened, dry room temperature t1, relative humidity RH1
The temperature t2 of cooling chamber, relative air humidity RH2
Then: according to the given value t1 of dry room 2, RH1, then can calculate the value (i.e. the dew-point temperature of dry room) of t0, again when the air in cooling chamber 4 is after evaporator cool-down dehumidification, during relative humidity RH2=100% in cooling chamber, so, when the value of t2 is reduced to t0, can ensure that the absolute humidity values of air in feeding dry room 2 is the absolute humidity values lower than air in dry room 2.
Embodiment:
Suppose dry room t1=3 DEG C, RH1=40%,
The dew-point temperature t0=-9.27 DEG C of dry indoor, (this dew-point temperature can be learnt according to the inquiry of humid air psychrometric chart)
So, air in cooling chamber 4 is after evaporator cool-down dehumidification, relative humidity RH2=100% in cooling chamber 4, when t2 is reduced to t0=-9.27 DEG C, the cold passage of dry room 2 could be opened, thus the time x that first point of arterial highway 52 time delay compressor is opened can be determined, namely t2 is reduced to the time of t0.
When compressor is opened, opening of time delay first point of arterial highway 52, decreases the relative humidity fluctuation of dry room 2, makes the relative humidity fluctuation in dry room 2 and average relative humidity realize reducing.Average relative humidity is the mean value of the relative humidity in dry room service time.After adopting which, the effect on moisture extraction of dry room 2 asks for an interview Fig. 2.Same, if delay first point of arterial highway 52 opened the startup changing time delay blower fan into, also can reduce the relative humidity fluctuation of dry room 2, make the relative humidity fluctuation in dry room 2 and average relative humidity realize reducing.When using time delay to enable the mode of blower fan 6, described first point of arterial highway 52 is in open mode always, or first point of arterial highway 52 is opened simultaneously when blower fan 6 starts, or first point of arterial highway 52 is opened after blower fan 6 starts.
Relative humidity fluctuation due to dry room 2 is general to produce when compressor start, so when the control method of this dry room 2 is usually used in compressor start, particularly, after defrost during compressor start.In order to more be conducive to reducing the average relative humidity of dry room 2 and the fluctuation of relative humidity, and reach the object of dehumidifying, after defrost, first point of arterial highway 52 opening time can after compressor second time starts Time Delay Opening again.Refer to Fig. 3, for compressor, defrost, dry room 2 first point of arterial highway 52 opening time and realize the logic control relation of dry room 2 relative humidity effect.
In sum, by the start-up time making be later than compressor the start-up time of the opening time of first point of arterial highway 52 or blower fan 6, thus the average relative humidity of dry room 2 and the fluctuation of relative humidity can be reduced.
Although be example object, disclose the preferred embodiment of the present invention, but those of ordinary skill in the art will recognize, when not departing from scope and spirit of the present invention disclosed in appending claims, various improvement, increase and replacement are possible.
