Referring to Fig. 1-Fig. 3, the unloading assembly 100 according to the multiple on-line system of the embodiment of the present invention is described.
With reference to shown in accompanying drawing, the unloading assembly 100 according to the multiple on-line system of the embodiment of the present invention comprises: compressor 1, oil eliminator 2 and unloading assembly 100.
Particularly, shown in figure 1, compressor 1 has exhaust outlet 11 and gas returning port 12, and oil eliminator 2 has entrance 21, oil return opening 22 and unloading port 23.Refrigerant after compressor 1 compresses can mix a part of lubricating oil when being discharged by the exhaust outlet 11 of compressor 1, then the refrigerant being mixed with lubricating oil enters oil eliminator 2 through entrance 21, by the process of oil eliminator 2, lubricating oil can be separated from refrigerant, isolated lubricating oil is discharged from oil return opening 22 and is come back in compressor 1 eventually through gas returning port 12, thus can utilize lubricating oil efficiently.By the isolated refrigerant of oil eliminator 2, according to the load needs of multiple on-line system, a part flows out from unloading port 23, and the remaining part that another part enters multiple on-line system from the outlet 24 of oil eliminator 2 carries out freezing or heating circulation.
With reference to shown in accompanying drawing, be connected with relief passage 3 between unloading port 23 and gas returning port 12, unloading assembly 100 is connected on relief passage 3, and unloading assembly 100 is configured to have reducing pressure by regulating flow effect and regulates the discharging quantity of the refrigerant of discharging from relief passage 3.Specifically, the high pressure refrigerant not participating in freezing or heating circulation flows out from unloading port 23, enters relief passage 3 and passes through the reducing pressure by regulating flow unloading assembly 100, reentering compressor 1 after becoming the refrigerant of low pressure by gas returning port 12.Simultaneously by regulating unloading assembly 100, the flow being expelled back into the refrigerant in compressor 1 from unloading port 23 can be regulated, to regulate discharging quantity according to actual conditions.Such as when the indoor set load in multiple on-line system is lower, the refrigerant that needs participate in freezing or heating circulation is just less, so we can regulate unloading assembly 100 to make the more refrigerant participating in circulation that do not need flow out from unloading port 23 and get back in compressor 1 after reducing pressure by regulating flow, identical principle, when the indoor set load in multiple on-line system is higher, need the refrigerant participating in circulation just more, unloading assembly 100 so can be regulated to make the less refrigerant participating in circulation that do not need flow out from unloading port 23 and get back to after reducing pressure by regulating flow in compressor 1.It can thus be appreciated that, by arranging unloading assembly 100, the discharging quantity of the refrigerant can discharged from relief passage 3 according to the payload regulable control of the indoor set in multiple on-line system, thus can the operational efficiency of raising multiple on-line system effectively.
Certainly, when the indoor set load in the fan-out capability and multiple on-line system of compressor 1 matches, unloading assembly 100 now can be regulated to make do not have refrigerant to flow out from unloading port 23, thus refrigeration or the heating needs of multiple on-line system can be ensured.
Be understandable that, unloading assembly 100 can be formed as any structure, as long as can carry out reducing pressure by regulating flow to refrigerant and for regulating the discharging quantity of refrigerant of discharging from relief passage 3.
According to the unloading assembly 100 for multiple on-line system of the embodiment of the present invention, by reasonably arranging unloading assembly 100 on relief passage 3, the discharging quantity of refrigerant can be regulated according to actual conditions, effectively improving multiple on-line system operational efficiency.
According to some embodiments of the present invention, shown in figure 1, unloading assembly 100 comprises: the first capillary 41, second capillary 42, first control valve 45 and the second control valve 46, first capillary 41 and the second capillary 42 are connected on relief passage 3, and the contiguous unloading port 23 of the first capillary 41 is arranged.First control valve 45 to be connected on relief passage 3 and between unloading port 23 and the first capillary 41.Second control valve 46 and the first capillary 41 or the second capillary 42 are connected in parallel.That is, can control whether have refrigerant to flow into unloading assembly 100 by the first control valve 45, the discharging quantity of the refrigerant flowing out relief passage 3 can be controlled by the second control valve 46.Wherein the second control valve 46 can be in parallel with the first capillary 41, and the second control valve 46 can also be in parallel with the second capillary 42, and in the example of fig. 1, the second control valve 46 is in parallel with the first capillary 41.
Specifically, by the control to the first control valve 45 and the second control valve 46, can control the discharging quantity of refrigerant, such as, when the load of indoor set is lower, the first control valve 45 and the second control valve 46 can be opened simultaneously, like this, the capillary in parallel with the second control valve 46 is by bypass, and only have the first capillary 41 or the second capillary 42 pairs of refrigerants to process, the discharging quantity of refrigerant can be more, thus less refrigerant participates in circulation, can meet the operation demand of the indoor set compared with Smaller load.When the load of indoor set is higher, the second control valve 46 can be closed while opening the first control valve 45, like this, first capillary 41 and the second capillary 42 process refrigerant simultaneously, thus the discharging quantity of refrigerant can be less, so just have more refrigerant and participate in circulation, and then the operation demand of the indoor set of satisfied larger load.When the load of indoor set increases further to that the fan-out capability of compressor 1 matches, so, the first control valve 45 and the second control valve 46 can be closed simultaneously, refrigerant is not unloaded, whole refrigerants all participates in circulation, can the operational efficiency of raising multiple on-line system effectively.
Particularly, first control valve 45 and the second control valve 46 can be respectively magnetic valve, magnetic valve can coordinate different circuit to realize the control of expection, and the precision controlled and flexibility can both ensure, and magnetic valve is common industrial equipment, cost is low and be easy to change, thus effectively can to reduce costs, and to be easy to the maintaining in later stage.
Shown in figure 1, the length of the first capillary 41 and the second capillary 42 is equal, thus can reduce the part type of unloading assembly 100, reduces cost.
According to other embodiments of the present invention, shown in figure 2, relief passage 3 comprises many subchannels in parallel, every sub-channels is all connected with gas returning port 12 with unloading port 23, unloading assembly 100 comprises multiple 3rd control valves 47 and multiple three capillary 43, and every sub-channels is in series with the 3rd control valve 47 and a three capillary 43.Alternatively, shown in figure 2, subchannel can be two, like this, while meeting refrigerant discharging quantity needs, can reduce the cost of unloading assembly 100, effectively improve production efficiency.
Be two for subchannel below and be respectively the first subchannel 31 and the second subchannel 32 control procedure to unloading assembly 100 to be described, shown in figure 2, when opening the 3rd control valve 47a of the first subchannel 31, the refrigerant of unloading is finally got back in compressor 1 by the first subchannel 31; As closedown the 3rd control valve 47a and when opening the 3rd control valve 47b of the second subchannel 32, the refrigerant of unloading is finally got back in compressor 1 by the second subchannel 32 simultaneously; When to open the 3rd control valve 47a and the 3rd control valve 47b simultaneously, the first subchannel 31 and the second subchannel 32 all unload refrigerant.
It can thus be appreciated that, every sub-channels all has the effect of unloading refrigerant and is independent of each other, can according to the workload demand of the indoor set of reality, select to open one or more or whole subchannels, that is, by controlling separately each sub-channels, different discharging quantities can be obtained, thus effectively improve the operational efficiency of multiple on-line system.
Particularly, the length of the three capillary 43 that many sub-channels are connected is different, and that is, the discharging quantity of every sub-channels is different, thus the control accuracy that further increasing refrigerant discharging quantity, and then further increasing the operational efficiency of multiple on-line system.Such as in the illustrated example shown in fig. 2, the three capillary 43a on the first subchannel 31 is longer, so the refrigerant discharging quantity of the first subchannel 31 is less, the three capillary 43b on the second subchannel 32 is shorter, so the refrigerant discharging quantity of the second subchannel 32 is larger.
Each 3rd control valve 47 can be magnetic valve, magnetic valve can coordinate different circuit to realize the control of expection, and the precision controlled and flexibility can both ensure, and magnetic valve is common industrial equipment, cost low and be easy to change, thus can effectively reduce costs, and be easy to the maintaining in later stage.
According to some embodiments more of the present invention, shown in figure 3, unloading assembly 100 comprises electric expansion valve 48 and the 4th capillary 44 of series connection.By the adjustment to electric expansion valve 48, the flow of refrigerant can be controlled, thus can control the discharging quantity of refrigerant, can number of parts be reduced when meeting and controlling discharging quantity, reduce the cost of unloading assembly 100.
The operation principle of the unloading assembly 100 of the multiple on-line system according to a specific embodiment of the present invention is briefly described below with reference to Fig. 1.
As shown in Figure 1, unloading assembly 100 comprises: the first capillary 41, second capillary 42, first control valve 45 and the second control valve 46, first capillary 41 and the second capillary 42 are connected on relief passage 3, and the first control valve 45 to be connected on relief passage 3 and between unloading port 23 and the first capillary 41.Second control valve 46 and the first capillary 41 are connected in parallel.
When indoor set load is less, opens the first control valve 45 and open the second control valve 46, first capillary 41 and do not participated in work by bypass, the discharging quantity of refrigerant is large, meets the demand only having fraction refrigerant to participate in circulation; When indoor set load is larger, opens the first control valve 45 and close the second control valve 46, first capillary 41 and the second capillary 42 and all participate in work, the discharging quantity of refrigerant is little, meets the demand that major part refrigerant participates in circulation; When the load of indoor set and the fan-out capability of compressor match, at this moment close the first control valve 45, refrigerant is not unloaded, thus the operating efficiency of refrigerant can be improved.
Unloading assembly 100 operation principle of the multiple on-line system according to another specific embodiment of the present invention is briefly described below with reference to Fig. 2.
As shown in Figure 2, relief passage 3 comprises two subchannels in parallel, and unloading assembly 100 comprises two the 3rd control valves 47 and two three capillaries 43, and every sub-channels is in series with the 3rd control valve 47 and a three capillary 43.The length of the three capillary 43a on the first subchannel 31 is greater than the length of the three capillary 43b on the second subchannel 32.
As closedown the 3rd control valve 47b and when opening the 3rd control valve 47a, the discharging quantity of refrigerant is minimum, it is now the refrigerant discharging quantity of the first subchannel 31; When opening the 3rd control valve 47b and close the 3rd control valve 47a, the discharging quantity of refrigerant gets a promotion, and is now the refrigerant discharging quantity of the second subchannel 32; When to open the 3rd control valve 47a and the 3rd control valve 47b simultaneously, the discharging quantity of refrigerant reaches maximum, is now the refrigerant discharging quantity sum of the first subchannel 31 and the second subchannel 32.
When indoor set list open minimum and need unloading time, the 3rd control valve 47b opens and the 3rd control valve 47a closes.When larger capacity opened by indoor set list or more than two are started shooting and need unloading, the 3rd control valve 47b closes and the 3rd control valve 47a opens.
