As shown in figure 1, the air conditioner of the present invention includes indoor set 1, outdoor unit 2 and the throttling arrangement being connected in major loop 3, throttling arrangement 3 is arranged in the connecting tube 4 between indoor set 1 and outdoor unit 2.Specifically, connecting tube 4 includes the first connecting tube 41 and second connecting tube 42, the internal diameter of the first connecting tube 41 be less than the internal diameter of the second connecting tube 42, that is to say, that the first connecting tube 41 be thin connecting tube, and the second connecting tube 42 is thick connecting tube.Wherein, the first connecting tube 41 and the liquid line 11 of indoor set 2 connect Logical, for the flowing of liquid refrigerants, the second connecting tube 42 connects with the gas piping 12 of indoor set 2, the stream for gaseous coolant It is dynamic.Throttling arrangement 3 is arranged in the first connecting tube 41, so as to effectively reduce energy loss of the refrigerant in connecting tube 4, is entered And improve the Energy Efficiency Ratio of complete machine.In order to clearly demonstrate beneficial effects of the present invention, with reference to refrigeration/system of existing air conditioner Pyrogen is managed carries out comparative illustration with the refrigerating/heating principle of air conditioner of the present invention.
Reference picture 2A, Fig. 2A are the refrigeration principle schematic diagrames of existing air conditioner.As shown in Figure 2 A, room is included in indoor set 1 Interior heat exchanger 10 (being now evaporator), outdoor unit 2 is interior to include outdoor heat exchanger 20 (being now condenser), compressor 21, four Port valve 22 (flow direction is arranged to kind of refrigeration cycle) and outdoor fan 23.Wherein, throttling arrangement 3 is arranged at the inner tube of outdoor unit 2 On road (position in Fig. 2A between A points and B points).Assuming that under specified cooling condition, indoor dry-bulb temperature is 27 DEG C, wet bulb temperature Spend for 19 DEG C, 35 DEG C of outside dry-bulb temperature, 24 DEG C of wet-bulb temperature.In kind of refrigeration cycle, compressor 21 discharges the gas of HTHP State refrigerant, into outdoor heat exchanger 20, after heat exchange (liquidation exothermic reaction principle), form medium temperature high-pressure liquid refrigerant (A in Fig. 2A Position), now the temperature of liquid refrigerants is 36-38 DEG C or so (being higher than extraneous circumstance temperature).Liquid refrigerants is carried out by throttling arrangement 3 After decompression, low-temp low-pressure gas-liquid mixed state refrigerant (B location in Fig. 2A) is formed, now the temperature of refrigerant is generally 10-12 DEG C.So Afterwards, refrigerant enters the first connecting tube 41 by stop valve 25, and the liquid line of machine 1 is got in after the first connecting tube 41 11, and then enter indoor heat exchanger 10 and exchanged heat.
In the structure of above-mentioned air conditioner, refrigerant is after outdoor heat exchanger 20 is exchanged heat, by the blower fan 23 in outdoor unit 2 Caused heat is taken away.First connecting tube 41, the second connecting tube 42 pass through attaching nut 13 and the liquid pipe of indoor set respectively Road 11 and gaseous state pipeline 12 connect.
In above-mentioned refrigerative circle system, the refrigerant due to entering the first connecting tube 41 is after the decompression of throttling arrangement 3 Gas-liquid mixed state refrigerant, because gaseous pressure drop is big, therefore, have certain pressure drop in the first connecting tube 41.Also, due to First connecting tube 41 is more in the part of outside, and the temperature for entering the refrigerant of the first connecting tube 41 is 10-12 DEG C, relative to Outdoor environment temperature (35 DEG C), both temperature difference are bigger, heat-proof device set in the first connecting tube 41, refrigerant is still It can be exchanged heat with the external world, that is, absorb the heat in the external world, cause the loss of refrigerant cold and the decline of Energy Efficiency Ratio.It is it can be seen that existing In air conditioner, energy loss of the refrigerant indoors in the first connecting tube 41 between machine 1 and outdoor unit 2 is larger.
Reference picture 2B, Fig. 2 B are the refrigeration principle schematic diagrames of the air conditioner of the present invention.As shown in Figure 2 B, in the present embodiment In, throttling arrangement 3 is arranged on the first connecting line 41 between indoor set 1 and outdoor unit 2.Assuming that under specified cooling condition, Indoor dry-bulb temperature is 27 DEG C, and wet-bulb temperature is 19 DEG C, 35 DEG C of outside dry-bulb temperature, 24 DEG C of wet-bulb temperature.Kind of refrigeration cycle In, compressor 21 discharges the gaseous coolant of HTHP, and into outdoor unit heat exchanger 20, (liquidation exothermic reaction is former after heat exchange Reason), medium temperature high-pressure liquid refrigerant (location A in Fig. 2 B) is formed, now the temperature of liquid refrigerants is 36-38 DEG C or so (higher than outer Boundary's circumstance temperature).Then the B location flowed directly into by stop valve 25 in the first connecting tube 41 arrival Fig. 2 B.Here, art technology Personnel are, it is understood that due in Fig. 2 B, there was only a stop valve 25, in the feelings that stop valve is opened between location A and B location Under shape, liquid refrigerants directly flows into the first connecting tube 41 through stop valve, because flow into the first connecting tube 41 is liquid refrigerants entirely, Pressure drop of the liquid refrigerants in the first connecting tube 41 is very small, and therefore, for liquid refrigerants after location A flow to B location, its temperature is same Sample is also at 36 DEG C or so, slightly above outer shroud temperature (35 DEG C).So, refrigerant the first pipeline 41 (enter throttling arrangement 3 it Preceding section) in will not absorb extraneous ardent (setting can outwardly shed a part of heat), therefore do not have in the section cold The loss of amount.Next, liquid refrigerants is depressured by throttling arrangement 3 again, the gas-liquid mixed refrigerant (figure of low-temp low-pressure is formed Location of C in 2B), now refrigerant temperature is generally 10 DEG C -12 DEG C, then immediately proceeds to the liquid line 11 of indoor set 1, then Indoor heat exchanger 10 is entered to be exchanged heat.
As noted previously, as liquid refrigerants, which first carries out decompression, enters back into the first connecting tube 41, refrigerant can be caused to connect first Loss of refrigeration capacity is larger during being flowed in adapter 41, and therefore, throttling arrangement 3 of the invention is arranged at indoor set 1 and outdoor unit 2 Between the first connecting line 41 on, liquid refrigerants flows directly into the first connecting tube 41, in the liquid line 11 of the machine of getting in 1 It is depressured before, so as to avoid the loss of liquid refrigerants cold in the first connecting tube 41, and then improves the energy of complete machine Effect ratio.
Above is contrast of the existing air conditioner with air conditioner of the invention on refrigeration mode, comes referring to Fig. 3 A and 3B Illustrate difference of the existing air conditioner with the air conditioner of the present invention on heating mode.
Reference picture 3A, Fig. 3 A are the heating principle schematics of existing air conditioner.As shown in Figure 3A, room is included in indoor set 1 Interior heat exchanger 10 (being now condenser), outdoor unit 2 is interior to include outdoor heat exchanger 20 (being now evaporator), compressor 21, four Port valve 22 (flow direction is arranged to heating circulation) and outdoor fan 23.Wherein, throttling arrangement 3 is arranged at the inner tube of outdoor unit 2 On road (position in Fig. 3 A between A points and B points).Assuming that under specified heating condition, indoor dry-bulb temperature is 20 DEG C, wet bulb temperature Spend for 15 DEG C, outside dry-bulb temperature is 7 DEG C, and wet-bulb temperature is 6 DEG C.In heating circulation, compressor 21 discharges HTHP Gaseous coolant, heat exchanger 10 is got in, after heat exchange (liquidation exothermic reaction principle), form medium temperature high-pressure liquid refrigerant, now The temperature of liquid refrigerants is 25 DEG C -32 DEG C or so.Liquid refrigerants flows into the first connection by liquid line 11 through attaching nut 13 Pipe 41.As can be seen from Figure 3A, liquid refrigerants need to only pass through stop valve 25 from location of C to B location, that is to say, that refrigerant is Temperature is at 25 DEG C -32 DEG C or so during one connecting tube 41 flows, and outer shroud temperature is 7 DEG C, and both temperature difference are larger, even in Heat-proof device is set in the first connecting tube 41, and refrigerant can still be exchanged heat with the external world, cause scattering and disappearing for refrigerant heat so that complete machine Energy Efficiency Ratio reduce.Refrigerant after B location, is depressured by throttling arrangement again, and it is cold to form low-temp low-pressure gas-liquid mixed state Matchmaker's (location A in Fig. 3 A), and then exchanged heat into outdoor heat exchanger 20.It can be seen that in existing air conditioner, refrigerant machine 1 indoors The energy loss in the first connecting tube 41 between outdoor unit 2 is larger.
Reference picture 3B, Fig. 3 B are the heating principle schematics of the air conditioner of the present invention.As shown in Figure 3 B, in the present embodiment In, throttling arrangement 3 is arranged on the first connecting line 41 between indoor set 1 and outdoor unit 2.Assuming that under specified heating condition, Indoor dry-bulb temperature is 20 DEG C, and wet-bulb temperature is 15 DEG C, and outside dry-bulb temperature is 7 DEG C, and wet-bulb temperature is 6 DEG C.Heating follows In ring, compressor 21 discharges the gaseous coolant of HTHP, gets in heat exchanger 10, and (liquidation exothermic reaction is former after heat exchange Reason), medium temperature high-pressure liquid refrigerant is formed, now the temperature of liquid refrigerants is 25 DEG C -32 DEG C or so.Liquid refrigerants passes through liquid line Road 11 flows into the first connecting tube 41 through attaching nut 13.As can be seen from Figure 3B, liquid refrigerants will pass through from location of C to B location Throttling arrangement 3, low-temp low-pressure gas-liquid mixed state refrigerant (B location in Fig. 3 B) is formed, now refrigerant temperature is generally 3 DEG C -5 DEG C Left and right, during now refrigerant flows in the first connecting tube 41, because outer shroud temperature is 7 DEG C, therefore refrigerant will not be outside Boundary radiates, and is arranged to absorb external heat, i.e., will not cause the loss of refrigerant heat.Then, refrigerant enters by stop valve 25 again Enter outdoor heat exchanger 20 to be exchanged heat.
As noted previously, as liquid refrigerants be not depressured before pass through the first connecting tube 41, cause liquid refrigerants because with the external world The temperature difference is larger and loses heat, and therefore, throttling arrangement 3 of the invention is arranged at the first connection between indoor set 1 and outdoor unit 2 On pipeline 41, liquid refrigerants is first depressured after entering the first connecting tube 41, and the liquid reduced with this in the first connecting tube 41 is cold The temperature difference between the temperature and outer shroud temperature of matchmaker, so as to avoid the loss of liquid refrigerants heat in the first connecting tube 41, enters And improve the Energy Efficiency Ratio of complete machine.
It was found from above-mentioned analysis, in cooling mode, for throttling arrangement 3 closer to indoor set 1, the liquid not being depressured is cold The distance that matchmaker is flowed in the first connecting tube 41 is longer, can more reduce the loss of refrigerant cold in the first connecting tube 41; Heating mode, throttling arrangement 3 closer to indoor set 1, the liquid refrigerants after being depressured flowed in the first connecting tube 41 away from From longer, the loss of refrigerant heat in the first connecting tube 41 can be more reduced.Therefore, throttling arrangement 3 can not set to lean on very much Nearly outdoor unit 2, otherwise can not realize the purpose for improving complete machine Energy Efficiency Ratio.
In addition, throttling arrangement is arranged at indoor set by some air conditioners.Because throttling arrangement can produce in the course of the work Noise, if throttling arrangement is arranged at into indoor set, noise will necessarily impact to user caused by throttling arrangement, reduce and use The usage experience at family.Therefore, although throttling arrangement 3 of the invention is arranged in the first connecting tube 41, can not be too near to Indoor set, to prevent noise caused by throttling arrangement 3 from being impacted to user.
Based on this, throttling arrangement 3 can neither be too near to indoor set, can not be too near to outdoor unit.Indoor set 1 and outdoor unit The first connecting tube 41 between 2 can be divided into outdoor section, indoor section and centre portion according to the state after its assembling, middle Section between outdoor section and indoor section and included in wall, throttling arrangement 3 can be disposed in the outdoor section with On the connecting portion or centre portion of centre portion.On the one hand, it is cold so as to reduce because the length of whole outdoor section is longer Loss of the matchmaker in the first connecting tube 41.On the other hand, due to throttling arrangement 3 be arranged at the outdoor section of the first connecting tube 41 with On the connecting portion or centre portion of centre portion, that is to say, that throttling arrangement 3 is located in wall or outdoor, thus throttling arrangement 3 noise hardly impacts to user.
As the preferred embodiment of the present invention, throttling arrangement 3 selects short-tube throttle valve, and the short-tube throttle valve is welded Onto the first connecting tube 41.In addition, throttling arrangement can also be capillary, expansion valve etc..Those skilled in the art can It is arranged in the first connecting tube 41 with the throttling arrangement from any matters, is no longer illustrated one by one herein.Wherein, if from hair Tubule can will access the first connecting line 41 as throttling arrangement 3 according to practical application scene after multiple capillary parallelings, So as to improve the Energy Efficiency Ratio of complete machine.
In summary, the first connecting tube of the invention by being arranged at throttling arrangement 3 between indoor set 1 and outdoor unit 2 On 41, energy loss of the refrigerant in the first connecting tube 41 can be effectively reduced.Under normal circumstances, indoor set 1 and outdoor unit 2 it Between the first connecting tube 41 (and second connecting tube 42) be copper pipe, throttling arrangement 3 can be welded in the by the way of welding One connecting tube 41, short-tube throttle valve is such as welded to the mode in the first connecting tube 41.It is arranged at throttling arrangement on outdoor unit Compare, it (is preferably the company of the outdoor section and centre portion of the first connecting tube 41 that throttling arrangement is arranged at into the first connecting tube 41 On socket part position or centre portion) on the energy loss of refrigerant can be obviously reduced.Compared with throttling arrangement is arranged on indoor set, Because throttling arrangement 3 is arranged on the connecting portion or centre portion of outdoor section and centre portion of the first connecting tube 41, That is throttling arrangement 3 is located in wall or outdoor, thus the noise of throttling arrangement 3 hardly impacts to user.This Outside, relative to the mode that throttling arrangement is set in machine indoors or outdoor unit, it is clear that set throttling arrangement in the first connecting tube Mode be more convenient, carry out larger change without to structure.So, not only eliminate in machine indoors or outdoor unit The cost of throttling arrangement is set, also simplify the internal structure of indoor set or outdoor unit.
So far, combined preferred embodiment shown in the drawings describes technical scheme, still, this area Technical staff is it is easily understood that protection scope of the present invention is expressly not limited to these embodiments.Without departing from this On the premise of the principle of invention, those skilled in the art can make equivalent change or replacement to correlation technique feature, these Technical scheme after changing or replacing it is fallen within protection scope of the present invention.
