The specific embodiment
Further specify the technical solution of the utility model below in conjunction with accompanying drawing and by the specific embodiment.
Preferred embodiment one:
Shown in Fig. 1, present embodiment provides a kind of condensation area adjustable refrigeration system, this refrigeration system comprises compressor 1, secondary condenser 4, the main condenser 5 that connects successively, and is connected the reversing arrangement 15 between secondary condenser 4 arrival ends and the port of export.The internal volume of secondary condenser 4 is less than the internal volume of main condenser 5.
Adjust secondary condenser by reversing arrangement in this preferred embodiment and whether add in the entry loop and together work with main condenser, realized the adjustment of condensation area.The internal volume of secondary condenser is less than the internal volume of main condenser, and other parts damage in the cooling system of Shi Buhui to guarantee to change condensation area.
Preferred embodiment two:
Present embodiment provides a kind of condensation area adjustable refrigeration system, and identical in this refrigeration system basic structure and the preferred embodiment one, difference is that the internal volume of the secondary condenser in the refrigeration system in the present embodiment is 20% of refrigeration system internal volume.Under such setting, the better effects if that this refrigeration system condensation area is regulated, and other parts in the protection system loop better.
When thermoacoustic refrigerator load hour (environment temperature is lower than 10 degree), the user is adjusted to the efficiently radiates heat area with first reversal valve and second reversal valve according to demand and only is main condenser.Namely do not have heat exchange owing to ending of reversal valve makes no flow of refrigerant in the secondary condenser this moment.This moment, the existence of secondary condenser can be ignored to the influence of the condensing pressure of refrigerator stable operation under this operating mode.Owing in the muffler assembly, designing reservoir is arranged simultaneously (the design liquid storage amount of reservoir 〉=20gR600a), (the main condenser design is relatively large, the secondary condenser design is less relatively even the internal volume of condenser coil changes, guarantee secondary condenser internal volume accounting≤20% in the internal volume of whole refrigeration system), can not occur return air temperature yet and spend the low phenomenon that causes the compressor liquid hammer.
Preferred embodiment three:
Please refer to shown in Figure 2, present embodiment provides a kind of condensation area adjustable refrigeration system, and this refrigeration system comprises compressor 1, secondary condenser 4, main condenser 5, filter 6, capillary 7, refrigerating evaporator 8, refrigeration evaporator 9 and the reservoir 10 that connects successively.Reversing arrangement is connected between secondary condenser 4 arrival ends and the port of export.
Enter or exclude refrigeration system, the reversing valve assembly that reversing arrangement adopts two reversal valve butt joints to form in order can more accurately secondary condenser 4 to be connected.Reversing arrangement is the butt joint reversing valve assembly; The butt joint reversing valve assembly comprises first reversal valve 2 and second reversal valve 3, the first reversal valve arrival end 21 is connected to the outlet of compressor 1, first outlet 22 of first reversal valve is connected to the entrance of secondary condenser 4, second outlet 23 of first reversal valve is connected to second outlet 33 of second reversal valve, the second reversal valve arrival end 31 is connected to the entrance of main condenser 5, and first outlet 32 of second reversal valve is connected to the outlet of secondary condenser 4.
First reversal valve and second reversal valve are connected to same controller, Synchronization Control.Namely when switch was in " ON ", first reversal valve and second reversal valve all were in opening; When switch was in " OFF ", first reversal valve and second reversal valve all were in closed condition.
Workflow: when the refrigerator work environment temperature is higher than 10 when spending, the switch that the user controls first reversal valve and second reversal valve is set to " OFF ", and this moment, first reversal valve and second reversal valve all were in closed condition.In this circulation, the first reversal valve arrival end and the first outlet conducting of first reversal valve, second outlet of first reversal valve ends; The second reversal valve arrival end and the first outlet conducting of second reversal valve, second outlet of second reversal valve ends;
Arrow is depicted as refrigerant flow direction among the figure.Cold-producing medium one tunnel flow through successively compressor 1, second reversal valve 2, secondary condenser 4, second reversal valve 3, main condenser 5, anti-condensation pipe, filter 6, capillary 7, refrigerating evaporator 8, refrigeration main evaporator 9, reservoir 10 flow back into compressor 1.
This moment, bigger area of dissipation can guarantee each chamber rate of temperature fall faster because the refrigerator work environment temperature is higher relatively, and thermic load is relatively large, and main condenser and secondary condenser are worked simultaneously.
When the refrigerator work environment temperature is lower than 10 when spending, the switch that the user controls first reversal valve and second reversal valve is set to " ON ", and this moment, first reversal valve and second reversal valve all were in opening.In this circulation, the first reversal valve arrival end and the second outlet conducting of first reversal valve, first outlet of first reversal valve ends; The second reversal valve arrival end and the second outlet conducting of second reversal valve, first outlet of second reversal valve ends.
Cold-producing medium one tunnel flow through successively compressor 1, first reversal valve 2, second reversal valve 3, main condenser 5, anti-condensation pipe, filter 6, capillary 7, refrigerating evaporator 8, refrigeration main evaporator 9, reservoir 10 flow back into compressor 1.
This moment is because the refrigerator work environment temperature is relatively low, thermic load is less relatively, only main condenser work, can suitably improve condensing pressure, the whole refrigeration system of effective shortening is set up pressure reduction under worst cold case be the time that system balancing needs, can guarantee the rate of temperature fall that each chamber is suitable relatively, reduce temperature fluctuation.
The reversal valve of two butt joints is formed reversing arrangement in this preferred embodiment, and structure is more reasonable, and sensitivity is higher, can realize adjusting the purpose of condensation area well.
Preferred embodiment four:
Present embodiment provides a kind of direct cooling refrigerator, and this direct cooling refrigerator comprises housing and is installed in the interior adjustable refrigeration system of condensation area of housing.The structure of the adjustable refrigeration system of this condensation area is identical with preferred embodiment three.
