Cool cycles according to the refrigerator of a preferred embodiment of the present invention is shown among Fig. 4 A.In other words, utilize refrigerant pipeline 34 be linked in sequence compressor 31, condenser 32, opening control device 40, first evaporimeter 27 and second evaporimeter 29, form a closed loop thus.Refrigerating fan 28 and freezing fan 30 be installed in first evaporimeter 27 and second evaporimeter 29 near.Particularly first evaporimeter 27 and second evaporimeter 29 are connected in series, and therefore, all refrigerant by first evaporimeter 27 all pass through second evaporimeter 29.
Shown in Fig. 4 A, its state changed when refrigerant flowed in refrigerant pipeline 34.Specifically, when refrigerant is evaporated during by first evaporimeter 27 and second evaporimeter 29 and absorbs heat from the air by evaporimeter 27 and 29, produce cold air thus.Running by means of refrigerating fan 28 and freezing fan 30 is sent into cold air in refrigerating chamber 22 and the refrigerating chamber 23.
Below the state change process of refrigerant will be described more specifically.
In compressor 31, refrigerant is compressed under HTHP, compressed refrigerant when flowing through condenser 32 by the heat exchange condensation.Compressed refrigerant is depressurized by opening control device 40 time, is evaporated when flowing into first evaporimeter 27 and second evaporimeter 29, produces cold air thus.
Heat by evaporimeter 27 and 29 is evaporated refrigerant owing to the operation of refrigerating fan 28 and freezing fan 30 by absorbing.Shown in Fig. 4 A, cold air is admitted to two chambers, so, these two chambers 23 and 22 all are cooled.
At this moment, because the temperature of the air in first evaporimeter 27 of refrigerating chamber 23 is higher than the temperature of air in second evaporimeter 29 comparatively speaking, so comparatively speaking, the refrigerant temperature of second evaporimeter 29 is low, and the refrigerant temperature height of first evaporimeter 27.
Refrigeration machine cooling loop according to another preferred embodiment is shown among Fig. 4 B.In other words, utilize refrigerant pipeline 34 that compressor 31, condenser 32, opening control device 40, second evaporimeter 29 and first evaporimeter 27 are connected in series, form a closed loop thus.Freezing fan 30 be installed in second evaporimeter 29 near, refrigerating fan 28 is installed near first evaporimeter 27.Here, in first preferred embodiment, refrigerant is at first by first evaporimeter 27, and then by second evaporimeter 29, yet in second preferred embodiment, refrigerant is at first by second evaporimeter 29, then by first evaporimeter 27.Remove outside the position difference of these two evaporimeters, second preferred embodiment is identical with first preferred embodiment, so below will second preferred embodiment do not elaborated.
In first and second preferred embodiment, compressor 31 and condenser 32 are that refrigerant is held under high pressure high-pressure side therein, and first and second evaporimeters are that refrigerant is held under low pressure low-pressure side therein.Opening control device 40 makes on high-tension side refrigerant decompression, and this refrigerant is discharged to low-pressure side.
Fig. 5 A is used to illustrate the drawing in side sectional elevation that is in the opening control device of closed condition when refrigerator is not switched on;
Fig. 5 B is used to illustrate the drawing in side sectional elevation of opening control device of a predetermined angle of being opened when refrigerator is energized; And
Fig. 5 C shows the aperture control range according to opening control device of the present invention, and it is opened scope and requires with the cooling of the cooling requirement of refrigerating chamber or refrigerating chamber and change.
Shown in Fig. 5 A, the inlet hole 41 that is used to suck the refrigerant that is condensed is fabricated on the part of opening control device 40, and is used for the discharge orifice 42 that the refrigerant of decompression is sent into first evaporimeter 27 is fabricated on another part of opening control device 40.In addition, be installed in a side of discharge orifice 42 according to the opening controller 43 of the opening degree of the state that opens or closes of power supply control discharge orifice 42.Here, the size of discharge orifice 42 is greater than the size of inlet hole, so that make the refrigerant decompression.
In opening control device 43, two silicon base 44 and 45 that will have different coefficient of thermal expansions are contained in the both sides of glassy layer 46 and become one.The heater 47 that is heated by external power source is rolled glassy layer 46, and the part of opening controller is fixed on the bottom of opening control device 40.
As described in Fig. 5 B, in opening control device 40, when heater 47 was heated after energising, silicon base 44 and 45 was owing to the heating of heater is expanded.Because the expansion rate of two substrates 44 and 45 differs from one another, so opening controller 43 is that the center is crooked up or down according to the variations in temperature of heater 47 with a standing part.
At this moment, if the coefficient of thermal expansion of top silicon base 44 greater than the coefficient of thermal expansion of bottom silicon base 45, opening controller 43 just is bent upwards a predetermined extent so, opens discharge orifice 42 thus, shown in Fig. 5 B.
At this moment, if from the external control power-on time, then the temperature that produced of heater 47 will change.The flexibility of opening controller 43 changes in the preset range R shown in Fig. 5 C, thereby can control the aperture of discharge orifice 42.
A kind of being used for is shown in Fig. 7 A according to the method for first preferred embodiment control refrigerator of the present invention.Shown in Fig. 7 A, the temperature T R of refrigerating chamber and the temperature T F of refrigerating chamber record in step S10.In step S11, with each reference temperature in addition relatively and determine whether to have at least a chamber need carry out cooling down operation with the temperature T R of freezer temperature TF and refrigerating chamber.If need in a chamber, to carry out cooling down operation at least at step S12, so will be in step S12 drive compression machine 31.In step 14, be that opening control device 40 was just opened a predetermined extent after compressor 31 and opening control device 40 connected power supplys, so the refrigerant pipeline between condenser 32 and two evaporimeters is also open-minded.More particularly, heater 47 is heated, because the expansion of silicon base 44 and 45, discharge orifice 42 is opened a predetermined extent, is depressurized a predetermined extent and flows into first evaporimeter 27 thereby be on high-tension side refrigerant.
In step S16,, will start refrigerating fan 28 for the heat exchange of the air of accelerating the refrigerating chamber in first evaporimeter 27.
In step S17, if refrigerating chamber 23 utilizes the operation of refrigerating fan 28 to begin to carry out cooling down operation, the aperture that will improve opening control device 40 so reduces the pressure reduction between high-pressure side and the low-pressure side thus so that increase the flow of refrigerant.At this moment, control module is connected the power supply be added on the heater so that the aperture of the discharge orifice of opening by opening controller 43 42 corresponding to the pressure reduction of high-pressure side and low-pressure side (that is, and P2), shown in Fig. 6 B like that.
In step S18, with the temperature T R of refrigerating chamber with predefined refrigerating chamber design temperature TR.S is compared in order to preserve fresh food at refrigerating chamber.Here, if temperature of refrigerating chamber TR is higher than refrigerating chamber degree of establishing temperature T R.S, so with regard to repeating step S14 to S17, thus according to refrigerating chamber design temperature TR.S refrigerated compartment.On the contrary, if temperature of refrigerating chamber TR is lower than refrigerating chamber design temperature TR.S so with regard to completing steps 20 in step 18.
Because refrigerating chamber 23 is according to refrigerating chamber design temperature TR.S cooling, so refrigerating chamber fan 28 is out of service in step 20, so just stop refrigerating operation.In step 22, start freezing fan 30 so that carry out refrigeration operation, accelerate heat exchange between the air of the air of second evaporimeter 29 and refrigerating chamber by starting freezing fan 30.
In step 24, in order to increase the pressure reduction between high-pressure side and the low-pressure side by the aperture that reduces opening control device 40, disconnect the power supply that is added on the heater, reduce the heat that produces by heater thus.Therefore, thereby the expansion that has reduced silicon base 44 and 45 has reduced the flexibility of opening controller 43, and the result has reduced the aperture of refrigerant pipeline.
Be the curve of pressure and entropy shown in Fig. 6 A,, will increasing the compression volume of compressor 31 in order in the refrigeration operation process, to keep the pressure reduction P1 between high-pressure side and the low-pressure side.
In step 26, with the temperature T F of refrigerating chamber with predefined refrigerating chamber design temperature TF.S is compared in order to preserve frozen food at refrigerating chamber.If freezer temperature TF is lower than refrigerating chamber design temperature TF.S, in step 28, just make freezing fan 30 out of service so here.At this moment, because compressor is out of service, cut off being added in the power supply on the opening control device 40 and making silicon base 44 and 45 contractions.Therefore, discharge orifice 42 is closed, the refrigerant of sever supply second evaporimeter 29.
Refrigerator controlling method according to second preferred embodiment of the present invention is shown among Fig. 7 B.Shown in Fig. 7 B, in step 110, detect freezer temperature TF and temperature of refrigerating chamber TR.In step 111, freezer temperature TF and temperature of refrigerating chamber TR are compared with corresponding reference temperature, determined whether that a chamber need carry out cooling down operation.If surpass separately reference temperature at step 111 freezer temperature TF or temperature of refrigerating chamber TR, just need carry out cooling down operation, the result has started compressor 31 in step 112.
In step 114, after connecting power supplys for compressor 31 and opening control device 40, opening control device 40 is just opened a predetermined extent, so open refrigerant pipeline between condenser 32 and two evaporimeters.More particularly, the heater of connecting power supply is heated, because the expansion of silicon base 44 and 45 makes discharge orifice 42 open a predetermined extent, thereby is in a reduce pressure predetermined extent and flowing in second evaporimeter 29 of on high-tension side refrigerant.
In step 116,, started freezing fan 30 in order to accelerate the heat exchange of refrigerating chamber air in second evaporimeter 29.
In step 117, if refrigerating chamber 22 utilizes the operation of freezing fan 30 to begin to cool down operation, will reduce the aperture of opening control device 40 so, so that reduce the flow of refrigerant, increase the pressure reduction of high-pressure side and low-pressure side thus.At this moment, control module disconnects the power supply be added on the heater 47, so that the aperture of the discharge orifice of being opened by opening controller 43 42 corresponding to the pressure reduction between high-pressure side and the low-pressure side (that is, P1) as shown in Figure 6A.
In step 118, predetermined refrigerating chamber design temperature TF.S is compared in order to preserve frozen food in refrigerating chamber together with freezer temperature TF.Here, if freezer temperature TF is higher than refrigerating chamber design temperature TF.s, so will repeating step S114 to S117, thus according to refrigerating chamber design temperature TF.S cooling refrigerating chamber.On the contrary, if freezer temperature TF is lower than refrigerating chamber design temperature TF.S in step 118, so just carry out step 120.
Because refrigerating chamber 22 is to cool off according to refrigerating chamber design temperature TF.S, so refrigerating chamber fan 30 is out of service in step 120, so stop refrigeration operation.In step 122, started refrigerating fan 28 so that carry out refrigerating operation, so accelerated heat exchange between the air of first evaporimeter 27 and the refrigerating chamber air owing to started refrigerating fan 28.
In step 124, in order to reduce the pressure reduction between high-pressure side and the low-pressure side by the aperture that increases opening control device 40, connect the power supply that is added on the heater 47, increase the heat that produces by heater thus.Therefore, increase the expansion of silicon base 44 and 45, promptly increased the degree of being bent upwards of opening controller 43, thereby increased the aperture of refrigerant pipeline.
Shown in Fig. 6 B is the curve of pressure and entropy, though the temperature of first evaporimeter 27 is higher than the temperature of second evaporimeter 29 in the refrigerating operation process, refrigerating chamber 23 still can be cooled to one and be suitable for effectively the temperature of cooling beverage or food therein.In order in the refrigerating operation process, to keep pressure reduction P2 between high-pressure side and the low-pressure side, reduce the compression volume of compressor 31.If the compression volume of compressor 31 reduces, the compressor desired power has just reduced so, has reduced the unnecessary driving power of compressor 31 thus.
In step 126, temperature of refrigerating chamber TR is all at refrigerating chamber preserves fresh food and predefined refrigerating chamber design temperature TR.S is compared.Here, if temperature of refrigerating chamber TR is lower than refrigerating chamber design temperature TR.S, then refrigerating fan 28 shuts down in step 128, and compressor 31 shuts down in step 130, stops refrigerating operation thus.At this moment, because compressor 31 is out of service, the power supply that is added on the opening control device 40 is cut off, thereby silicon base 44 and 45 is shunk.Therefore, discharge orifice 42 is closed, and cuts off to first evaporimeter 27 and carry refrigerant.
As mentioned above, thus refrigerator of the present invention has and is used to control refrigerant flow so that change the opening control device that pressure reduction between high-pressure side and the low-pressure side reduces the power drive loss of compressor and improves capacity usage ratio.
