Description
The present invention relates to a kind of refrigerator, relate to the refrigerator that has refrigerating chamber usefulness evaporimeter and refrigerating chamber usefulness evaporimeter respectively in more detail.
Usually, refrigerator is used for freezing or stored refrigerated beverage food etc.
As shown in Figure 1, refrigerator forms spatial accommodation by shell 10, and spatial accommodation is separated into refrigerating chamber 10a and refrigerating chamber 10b, and the door 12 of above-mentioned refrigerating chamber 10a of switch and refrigerating chamber 10b has been installed in a side of above-mentioned shell 10.The machine of finishing the temperature of kind of refrigeration cycle reduction refrigerating chamber 10a and refrigerating chamber 10b is made of compressor 20, condenser 30, capillary 40 (with reference to Fig. 2) and evaporimeter.
The above-mentioned evaporimeter of large-capacity refrigerator is provided with refrigerating chamber evaporimeter 50 and refrigerating chamber evaporimeter 52 respectively.Above-mentioned each evaporimeter 50,52 is arranged on the outside of refrigerating chamber 10a, refrigerating chamber 10b, and is made of fin-type heat exchanger, so that have higher heat exchanger effectiveness.Also be provided with air freezing, refrigerating chamber 10a, 10b is flowed through fan 60,62 that each evaporimeter 50,52 circulates equally respectively, the motor 70 that drives above-mentioned each fan 60,62 uses the constant speed induction machines.In order to remove, on above-mentioned each evaporimeter 50,52, be provided with defroster (not shown)s such as Defrost heater because of temperature difference causes the frost that airborne condensate moisture is tied.
Below, with reference to Fig. 1 and Fig. 2 common refrigerator course of action is described.
At first, compressor 20 is compressed into HTHP with the gaseous refrigerant of low-temp low-pressure.The gaseous refrigerant that is compressed into HTHP is cooled through condenser 30 and condenses into high-pressure liquid.The liquid refrigerant temperature and pressure of high pressure descends when flowing through capillary 40.Then, in each evaporimeter 50,52, become the gaseous refrigerant of low-temp low-pressure from draw heat on every side, and with the surrounding air cooling of each evaporimeter 50,52.At this moment, the air by each evaporimeter 50,52 cooling blows to refrigerating chamber 10a, refrigerating chamber 10b under the effect of fan 60,62.Be that refrigerating chamber 10a, refrigerating chamber 10b are cooled off by each evaporimeter 50,52 in the process of each fan 60,62 circulating air.The frost of being tied on above-mentioned each evaporimeter 50,52 is dissolved it by defroster and is discharged to the outside by the drainage channel (not shown).
The connected mode of above-mentioned each evaporimeter 50,52 is divided into parallel and two kinds of tandems.Tandem is that the refrigerant pipe of the supply system cryogen is connected with another evaporimeter through after in two evaporimeters any one earlier again.And parallel be to be mode from main refrigerant pipe branch to the refrigerant pipe of each evaporimeter the supply system cryogen.
Fig. 2 illustrates parallel, flows into refrigerant amount in the refrigerant pipe of each evaporimeter 50,52 according to the temperature of refrigerating chamber 10a and refrigerating chamber 10b, regulates by adjusting devices such as triple valves 80 at the branch point of each refrigerant pipe.
Promptly, when the temperature that the temperature of refrigerating chamber 10b is lower than design temperature, refrigerating chamber 10a was higher than design temperature, triple valve 80 cut off refrigerating chambers and connects refrigerating chamber makes refrigerant flow direction refrigerating chamber usefulness evaporimeter 50 with the refrigerant pipe of evaporimeter 50 refrigerant pipe with the refrigerant pipe of evaporimeter 52.Like this, refrigerating chamber is better brought into play with the cooling effect of evaporimeter 50, and the temperature of refrigerating chamber 10a sharply descends.On the contrary, when the temperature of refrigerating chamber 10b is higher than design temperature, refrigerant flow direction refrigerating chamber 10b and the temperature of refrigerating chamber 10b is sharply descended.Certainly, reduce to design temperature simultaneously when following in the temperature of refrigerating chamber 10a, refrigerating chamber 10b, compressor 20 quits work, and cold-producing medium also just stops to flow.As a result, compare the different and thermodynamics loss that causes of the temperature range that can reduce refrigerating chamber 10a, refrigerating chamber 10b with the situation of using an evaporimeter to cool off refrigerating chamber 10a, refrigerating chamber 10b simultaneously.
At this moment, because each fan 60,62 of the air circulation in refrigerating chamber 10a, the refrigerating chamber 10b is driven by constant speed induction machine 70, so the adjustment of refrigerating chamber 10a, refrigerating chamber 10b is undertaken by the work of regulating the refrigerant amount that flows into each evaporimeter 50,52 and compressor 20.
On the other hand, be arranged on the situation of refrigerating chamber 10a outside with evaporimeter 50 for above-mentioned refrigerating chamber, consider the characteristic that refrigerating chamber 10a is maintained the low temperature below 0 ℃, the defroster that can produce heating functioin as Defrost heater etc. can not be set, and therefore the airborne moisture of condensation becomes white and deposits owing to heat exchange action.Therefore, heat exchanger effectiveness will descend at leisure.
Refrigerating chamber is arranged on evaporimeter 52 refrigerating chamber 10b the outside refrigerator and refrigerating chamber with evaporimeter 50 the same in refrigerating chamber 10b also difficulty establish defroster.Moreover, even defroster is set, aspect the structure of the evaporimeter 52 that is referred to as fin-type heat exchanger, frost occurs dissolves into water and the steam that produces is difficult for discharging and being trapped in indoor in the defrosting effect.Therefore, the steam corruption causes the preservation state of the food deposited in the refrigerating chamber 10b to worsen.
Each evaporimeter 50,52 is being arranged under the situation of refrigerating chamber 10a, refrigerating chamber 10b inside, above-mentioned each fan 60,62 also must all be arranged on the inside of refrigerating chamber 10a, refrigerating chamber 10b.Like this, because of each fan 60,62 is set the capacity of refrigerating chamber 10a, the actual use of refrigerating chamber 10b is reduced.
According to above-mentioned prior art, because must regulate the refrigerant amount that flows into each evaporimeter 50,52, so need triple valve 80 grades to establish mechanism in addition according to the temperature of refrigerating chamber 10a, refrigerating chamber 10b.Will increase the manufacturing cost of refrigerator thus, the noise that above-mentioned triple valve 80 produces when moving descends the commodity performance of refrigerator.
And 10a is different with refrigerating chamber, and the food among the refrigerating chamber 10b is to preserve under the non-state that freezes.Therefore, air is hydrogenesis in the process of evaporimeter 52 of flowing through, and supplies with refrigerating chamber 10b by fan 62 under the state of water deficient, and the frost that dissolves on the evaporimeter 52 when defroster moves is discharged to the outside by the drainage channel that other establishes, so that its temperature descends, the food of keeping is easy to drying.
