Describe in detail
The wind direct freezing combination multiple temperature control refrigerator working method that is provided with ice machine of the present invention and each parts are composed as follows:
Refrigerator ice cube refrigerating chamber 1 of the present invention and refrigerating chamber 2 in refrigerating chamber 1, arrange an ice-making compartment, and described ice-making compartment is equipped with ice-making compartment door 9, can play that isolated cold flows and the effect of taint of odour; Ice machine is fixed in the ice-making compartment, under described ice machine, ice bank is set; Refrigerating chamber adopts direct-cooled mode, and refrigerating chamber also adopts direct-cooled mode, in the evaporimeter space of refrigerating chamber one air inlet 7 is set again and an air outlet 6 leads to ice-making compartment, utilizes air-cooled mode that ice-making compartment is carried out degree of depth cooling when needing.
On the air outlet 6 of ice-making compartment and/or air inlet 7, can install one can rotary opening closing door, when the refrigerating chamber space that the ice-making compartment conduct is commonly used, close described door, like this, refrigerating chamber also is that the direct-cooled mode that adopts is carried out freezing, if change ice-making compartment into the deep-freezing chamber, namely, in described ice-making compartment 3, ice machine is not set, in fact, described refrigerator has just consisted of the air-cooled and direct-cooled in conjunction with refrigerator of double evaporators three temperature three controls,, can independently control as required the cold of refrigerating chamber, refrigerating chamber and ice-making compartment that is.
Direct-cooled employing plate evaporator at the refrigerating chamber of refrigerator of the present invention, because the pressured adhesion technique of dull and stereotyped plate evaporimeter is attached at refrigerating chamber inner bag rear wall top, freeze by free convection, after indoor temperature reaches design temperature therebetween, refrigeration thermostat sends pulse signal to impulse electromagnetic valve, the pulse electromagnetic valve events cuts off the refrigeration circulation of cold-producing medium.
Described plate evaporator because be attached to refrigeration inner bag the inside, its have evaporimeter hide, do not influence outward appearance, refrigeration evenly, should not cause characteristics such as article frostbite.
Refrigerating chamber adopts plate evaporator, has kept the humidity of refrigerating chamber to a certain extent.
Referring to Fig. 1, Fig. 1 (b) is the air-cooled and direct-cooled cutaway view in conjunction with multiple temperature control refrigerator that is provided with ice machine of the present invention, can be well understood to each position component and connected mode from this figure.
In refrigerator of the present invention, what refrigerating chamber adopted also is direct-cooled mode, the one side of evaporimeter also is close to refrigerating chamber inner bag the inside, but, form a gap behind its another side, flow through on it from the air of ice-making compartment, through entering ice-making compartment after the cooling once again, ice-making compartment adopts air-cooled refrigeration modes, makes the chilling rate of ice making ice-making compartment apparently higher than the chilling rate of simple use direct-cooled mode.
Therefore, ice-making compartment adopts air-cooled and direct-cooled mixing ice-make mode, is equivalent to form two controlled warm areas at refrigerating chamber.
Owing to adopt air-cooled and direct-cooled hybrid mode refrigeration at refrigerating chamber, in order to improve the refrigerating efficiency of ice-making compartment, the evaporimeter of refrigerating chamber has adopted finned evaporator, in order to prevent the cold deficiency of the relative refrigerating chamber supply of finned evaporator, whole or a part of good materials of thermal conductivity that adopt of ice-making compartment are as dividing plate, for example, metallic aluminium, like this, the cold of ice-making compartment can carry out heat exchange by dividing plate, again because ice-making compartment preferably is arranged on the top of refrigerating chamber, therefore, the cold air of ice-making compartment outer wall descends, thereby has formed the circulation that a heat exchange is arranged.
Many temperature controls of the present invention are meant according to refrigeration or freezing demand to refrigerating capacity, cold-producing medium flows to refrigerating chamber or refrigerating chamber by impulse electromagnetic valve, the temperature of two Room is controlled at ice-making compartment by each indoor temperature controller temperature-sensitive head perception disease by the controller of refrigerator respectively action sensor is set, perhaps the circuit of ice-making compartment and total control circuit of refrigerator are connected, with the working condition of perception ice machine.
Judge whether ice making is carried out,, start freezer evaporator, and the unlatching fan makes ice-making compartment reach the ice making quick freezing temperature rapidly if ice making begins;
Judge that ice-making compartment is in the temperature maintenance state,, start freezer evaporator, and the unlatching fan makes ice-making compartment reach the ice making holding temperature rapidly if temperature does not reach the ice making holding temperature of appointment;
Because the assigned temperature and the holding temperature of ice-making compartment are lower than the refrigerating chamber assigned temperature, therefore, under described situation, the temperature of refrigerating chamber should maintain below the refrigerating chamber assigned temperature always.
The preferred ice-making compartment holding temperature that adopts equals the refrigerating chamber assigned temperature, and when freezer temperature does not reach assigned temperature, refrigerating chamber needs cold, cold-producing medium is walked major loop, because the main evaporator area of refrigerating chamber is less, therefore, the cold that refrigeration evaporator discharges is few, and the decline of temperature of refrigerating chamber is very little; When adopting the ice-making compartment of metal partion (metp), the heat of refrigerating chamber and ice-making compartment fully exchanges.
In order to improve the ice making efficient of ice-making compartment, promptly, make ice-making compartment keep one as far as possible than refrigerating chamber temperature more, adopt the good shelf of thermal insulation between ice-making compartment and the refrigerating chamber, and make ice-making compartment quick freezing temperature and holding temperature all be starkly lower than the refrigerating chamber assigned temperature, in the case, ice-making compartment has formed a dark refrigerating chamber under the situation of not placing ice machine.
When refrigerating chamber reaches assigned temperature, and refrigerating chamber no show assigned temperature, open bypass circulation, the refrigerating chamber main evaporator that the area of major loop is less and the bigger refrigerating chamber additional vaporization device of area are combined into the very big refrigerator evaporator of area, promptly regulate temperature of refrigerating chamber.Refrigeration system.
Refrigerator of the present invention comprises compressor, condenser, device for drying and filtering, capillary, refrigerating evaporator, refrigerating chamber, refrigeration evaporator.Refrigerating chamber, air intake duct.
In the present invention, what refrigerating chamber adopted is plate evaporator, and what refrigerating chamber adopted is finned evaporator.
Next we see the mode of refrigeration system, prior art discloses evaporimeter parallel construction (discrete pair of loop structure) or added a subsidiary loop in the series arrangement of traditional evaporimeter, these two kinds of structures, refrigerating chamber and refrigerating chamber can be controlled respectively substantially, but still have shortcomings such as the thermodynamics irreversible loss is very big, air intake duct appearance dewfall.
The present invention proposes to insert the bigger evaporimeter of area as refrigerating chamber additional vaporization device again in the bypass circulation of the two cycle refrigerator of bypass, therefore the evaporator area of refrigerating chamber is very big, it is shorter that bypass capillary can design, because even flow is very big, but because the refrigeration evaporator area is big, cold-producing medium will all evaporate in evaporimeter, basic no liquid cold-producing medium inhale pipe; When refrigerating chamber does not need cold, and refrigerating chamber needs cold, and cold-producing medium is walked major loop, because the evaporator area of former refrigerating chamber is less, therefore, the cold that refrigeration evaporator discharges is few, and the decline of temperature of refrigerating chamber is very little.
Therefore, the cold major part of refrigerating chamber is from bypass circulation, because bypass capillary is shorter in the bypass circulation, and the evaporating temperature height, the thermodynamics irreversible loss is little, the COP height of system.
Of the present invention pair of cycle refrigerator, comprise compressor 11, condenser 12, device for drying and filtering 13, three-way magnetic valve 14, main capillary 15, bypass capillary 16, refrigerating evaporator 17, former refrigeration evaporator 19, reservoir 20, also comprise an additional refrigeration evaporator 18 at described bypass closed circuit, compressor 11 outlets are connected with condenser 12 imports, condenser 12 outlets are connected with device for drying and filtering 13 imports, device for drying and filtering 13 outlets are connected with three-way magnetic valve 13 inlets, an outlet of three-way magnetic valve 14 is connected with main capillary 15 imports, another outlet is connected with bypass capillary 16 imports, main capillary 15 outlets are connected with refrigerating evaporator 17 imports, bypass capillary 16 outlets are connected with additional refrigeration evaporator 18 imports, refrigerating evaporator 17 outlets and 18 outlets of additional refrigeration evaporator all are connected with former refrigeration evaporator 19 imports, former refrigeration evaporator 19 outlets are connected with reservoir 20 imports, reservoir 20 outlets are connected with air intake duct one end, and the other end of air intake duct is connected with compressor 11 inlets.
Refrigeration system of the present invention is compared with single loop system has following advantage:
The influence of environment temperature be can avoid, the optimal allocation and the utilization of energy realized the refrigerating indoor temperature;
Because the double round robin cooling system can be controlled refrigerating chamber and freezer temperature independently, so its refrigerating capacity is far longer than common single round-robin system cooling system refrigerator, two cycle refrigerator refrigerating fluctuations in indoor temperature scope in refrigerating process is far smaller than the single cycle refrigerator, and less temperature fluctuation will help the storage fresh-keeping of food.
For the double round robin cooling system, when design, can select bigger refrigerator evaporator, be easy to make refrigerator to satisfy the hot conditions requirement like this, and when low ambient temperature, as long as the refrigerating chamber design temperature is lower than environment temperature, refrigerator can fully normally move under without any the heating compensation condition.
Refrigerator of the present invention, a kind of two cycle refrigerator of the variable bypass of disengagement area that refrigerate have been proposed, the researcher thinks, the two energy-conservation factors of cycle refrigerator of bypass that influence refrigeration disengagement area is variable, be mainly the factor such as system COP of refrigerating chamber load, bypass circulation load and major cycle, bypass circulation and the functional relation of energy-saving effect, use this functional relation, under the actual condition of present refrigerator, refrigerator of the present invention is than evaporator series single cycle refrigerator energy-saving about 12%.
Compressor in the refrigerator of the present invention is the steam compression type compressor, mainly comprise compressor 11, condenser 12, capillary 15,16, device for drying and filtering 13, three-way magnetic valve 14, with evaporimeter 17,18,19, described steam compression type refrigeration circulation, constantly circulate through overcompression, condensation, throttling, four processes of evaporation, the periodic generation of cold-producing medium becomes liquid from steam, becomes the state variation of steam from liquid, constantly the transfer of heat in the refrigerator is arrived the refrigerator outside, thereby reach the refrigeration purpose.
In refrigerator of the present invention, the cold-producing medium of employing is R134a, in non-most preferred embodiment of the present invention, also can adopt other known cold-producing mediums in the prior art;
Researcher of the present invention is when design refrigerator of the present invention, detailed research has been carried out in configuration at the simplified parameter of the configuration of the configuration of refrigeration system, evaporimeter, evaporimeter, and draw final design conclusion, because the present invention is to the configuration of prior art, make noise reduction, the thermal efficiency of refrigerator of the present invention improve, specific as follows:
At first, prior art shows that flat (direct-cooling type) evaporimeter is the temperature that is reduced by the free convection of its surface low-temperature in the refrigerator, and its advantage is that humidity is suitable, fresh keeping property is good, dischargeable capacity is big under the power saving, equal volume; And finned evaporator (air-cooled) is to force to be blown in the case space by cold air by the air channel to cause circulation, advantage be automatic defrosting, temperature evenly, shortcoming is that refrigerating chamber humidity is low, the easy air-dry dehydration of food, the power consumption height, dischargeable capacity is low.
The characteristics of refrigerator of the present invention are freezing and refrigeration is all adopted direct-cooled, the direct-cooled employing finned evaporator of refrigerating chamber, the disappearance of refrigerating chamber cold adopts the heat transfer of ice-making compartment dividing plate to remedy, and ice-making compartment adopts air-cooled mode, as aforementioned, adopt the cold of air-cooled ice-making compartment, also can carry out freezing to refrigerating chamber by described shelf conduction.
At characteristics of the present invention, conventional finned evaporator is used to carry out in refrigerating chamber direct-cooledly will produce certain problem, researcher of the present invention has carried out further studies show that to finned evaporator, the efficient of finned evaporator is subjected to influence of various factors, referring to Fig. 2 (a) to Fig. 2 (f).
Conclusion is that relative air humidity is bigger to the performance impact of finned evaporator, especially under the situation of high humility, along with the evaporimeter prolongation of running time, evaporator effectiveness (η
0) and air side average heat transfer coefficient (K
0) sharply descend, therefore, the control relative air humidity has material impact to evaporimeter.
In addition, spacing of fin is also very big to the performance impact of evaporimeter, wide spacing evaporator fin heat exchange property is obviously because close spacing evaporator fin, when the about 4mm of spacing of fin, performance of evaporator sharply worsens, under the worst cold case, the pitch of fins of evaporator fin adopts more than the 6mm as far as possible, the pitch of fins 6-8mm of preferred evaporator fin.
In view of air cooling refrigeration has fireballing characteristics, and the humidity height of ice-making compartment might reduce the efficient of evaporimeter, in view of such contradiction, therefore decision be chosen in the refrigerating chamber finned evaporator mode and in conjunction with the isoparametric selection of evaporator fin so that reach a comparatively desirable balance.
For further screening, the shape of researcher's finned evaporator of the present invention is screened, and is as follows referring to the geometric parameter of accompanying drawing 3,4, three kind of heat exchanger:
Conclusion shows that in the air-cooled and direct-cooled hybrid mode of refrigerating chamber of the present invention, the efficient of No. 3 evaporimeters is better than other two kinds of evaporimeters, in the present invention as preferred embodiment.
In order to obtain best efficient, refrigerating chamber of the present invention adopts two kinds of different evaporimeters with refrigerating chamber, wherein:
Adopting evaporimeter in the refrigerating chamber of described refrigerator is finned evaporator, and refrigerating chamber freezes by direct-cooled mode, and ice-making compartment is forced to carry out an indoor air convection by freezing blower fan and reached the refrigeration purpose; After the ice-making compartment temperature reaches design temperature; Freezing blower fan stops, if freezer temperature does not reach assigned temperature as yet, freezer evaporator works on, if freezer temperature also reaches assigned temperature, then freezing temperature controller sends pulse signal to impulse electromagnetic valve, and the pulse electromagnetic valve events cuts off the freezing kind of refrigeration cycle of cold-producing medium;
