With reference to Fig. 2A, Fig. 2A is the refrigeration principle schematic diagram of existing air conditioner.As shown in Figure 2 A, room is included in indoor unit 1
Interior heat exchanger 10 (being at this time evaporator), outdoor unit 2 is interior to include outdoor heat exchanger 20 (being at this time 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 high temperature and pressure
State refrigerant, into outdoor heat exchanger 20, after heat exchange (liquidation exothermic reaction principle), forms medium temperature high-pressure liquid refrigerant (A in Fig. 2A
Position), the temperature of liquid refrigerants is 36-38 DEG C or so (higher than extraneous circumstance temperature) at this time.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, the temperature of refrigerant is generally 10-12 DEG C at this time.So
Afterwards, refrigerant enters the first connecting tube 41 by shut-off 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 exchange heat.
In the structure of above-mentioned air conditioner, refrigerant is after outdoor heat exchanger 20 is exchanged heat, by the wind turbine 23 in outdoor unit 2
The heat of generation is taken away.First connecting tube 41, the second connecting tube 42 pass through attaching nut 13 and the liquid pipe of indoor unit 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, since gaseous pressure drop is big, 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 exchange 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 as 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.

In ring, compressor 21 discharges the gaseous coolant of high temperature and pressure, 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, the temperature of liquid refrigerants (is higher than outer for 36-38 DEG C or so at this time
Boundary's circumstance temperature).Then the B location in the first connecting tube 41 arrival Fig. 2 B is flowed directly into by shut-off valve 25.Here, art technology
Personnel are, it is understood that due in Fig. 2 B, there was only a shut-off valve 25, in the feelings that shut-off valve is opened between location A and B location
Under shape, liquid refrigerants directly flows into the first connecting tube 41 through shut-off valve, since 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 slightly above outer shroud temperature (35 DEG C) also at 36 DEG C or so.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), refrigerant temperature is generally 10 DEG C -12 DEG C at this time, then immediately proceeds to the liquid line 11 of indoor unit 1, then
Indoor heat exchanger 10 is entered to exchange 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, the throttling arrangement 3 of the utility model is arranged at indoor unit 1 and room
On the first connecting line 41 between outer machine 2, liquid refrigerants flows directly into the first connecting tube 41, in the liquid of the machine of getting in 1
It is depressured before pipeline 11, so as to avoid the loss of liquid refrigerants cold in the first connecting tube 41, and then is improved whole
The Energy Efficiency Ratio of machine.

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 high temperature and pressure
Gaseous coolant, gets in heat exchanger 10, after heat exchange (liquidation exothermic reaction principle), forms medium temperature high-pressure liquid refrigerant, at this time
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 shut-off 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, both temperature difference are larger, even in
Heat-proof device is set in the first connecting tube 41, and refrigerant can still exchange 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 exchange heat into outdoor heat exchanger 20.As 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.

Reason), medium temperature high-pressure liquid refrigerant is formed, the temperature of liquid refrigerants is 25 DEG C -32 DEG C or so at this time.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, forms low-temp low-pressure gas-liquid mixed state refrigerant (B location in Fig. 3 B), refrigerant temperature is generally 3 DEG C -5 DEG C at this time
Left and right, during refrigerant flows in the first connecting tube 41 at this time, since outer shroud temperature is 7 DEG C, 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 again by shut-off valve 25 into
Enter outdoor heat exchanger 20 to exchange 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, the throttling arrangement 3 of the utility model is arranged at first between indoor unit 1 and outdoor unit 2
On connecting line 41, liquid refrigerants is first depressured after entering the first connecting tube 41, reduces the liquid in the first connecting tube 41 with this
The temperature difference between the temperature and outer shroud temperature of state refrigerant, so as to avoid the damage of liquid refrigerants heat in the first connecting tube 41
Lose, and then 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 unit 1, the liquid not being depressured is cold
