It should be noted that First Heat Exchanger 30 can be disposed in the outdoor, the second heat exchanger 40 can be disposed in the interior.When
When air-conditioning system 100 works in cooling mode, as shown in Fig. 2 from the exhaust outlet 120 of compressor 10 flow out cooling medium successively
Along arrow：Flow direction flowing shown in a1 → a2 → a3 → a4 → a5 → a6 → a7 → a8, is finally returned to from gas returning port 110
In compressor 10, to complete circulating for cooling medium.Specifically, as shown in Fig. 2 the high temperature compressed through compressor 10, height
The cooling medium of pressure sequentially passes through the first valve port 210 and the second valve port 220 from first after the discharge compressor 10 of exhaust outlet 120
Port 310 is entered in the First Heat Exchanger 30 of outdoor, and high temperature, the gaseous cooling medium of high pressure condense in First Heat Exchanger 30
Heat release, liquid is mutually changed into from gaseous state.Cooling medium flows out First Heat Exchanger 30 from second port 320 and enters throttling arrangement 50,
Cooling medium is flowed into the second heat exchanger 40 in further decompression, the cooling of throttling arrangement 50 from the 3rd port 430.Low temperature
Cooling medium heat absorption evaporation in the second heat exchanger 40, so as to reach the effect of indoor refrigeration.It is cold after heat exchange
But medium flows out the second heat exchanger 40 from the 4th port 440, and flows successively through the 3rd valve port 230, the 4th valve port 240, finally from
Gas returning port 110 flows back to compressor 10.
When air-conditioning system 100 works in a heating mode, as shown in figure 3, from the exhaust outlet 120 of compressor 10 flow out it is cold
But medium is secondary along arrow：Flow direction flowing shown in b1 → b2 → b3 → b4 → b5 → b6 → b7 → b8, finally from gas returning port
110 return in compressor 10, to complete circulating for cooling medium.Specifically, as shown in figure 3, being compressed through compressor 10
High temperature, high pressure cooling medium sequentially pass through the first valve port 210, the 3rd valve port 230 after being flowed out from the exhaust outlet 120 of compressor 10
And entered from the 4th port 440 in the second heat exchanger 40 of interior, high temperature, the gaseous cooling medium of high pressure are in the second heat exchanger
Heat release condenses in 40, is mutually changed into liquid from gaseous state, so as to reach the effect of indoor heating.Subsequent cooling medium is from the 3rd port
430 flow into throttling arrangement 50, and cooling medium is flowed into room in further decompression, the cooling of throttling arrangement 50 from second port 320
In outer First Heat Exchanger 30.The heat absorption evaporation in First Heat Exchanger 30 of the cooling medium of low temperature, it is cold after heat exchange
But medium flows out First Heat Exchanger 30 from first port 310, and flows successively through the second valve port 220, the 4th valve port 240, finally from
Gas returning port 110 flows back to compressor 10.
It should be noted that air-conditioning system 100 is in the case where freezing and heating different working modes, cooling medium is in air-conditioning system
Flow direction in 100 is different.There is different phases in First Heat Exchanger 30 and in the second heat exchanger 40 due to cooling medium
State changes, for example, cooling medium is mutually changed into liquid in condenser from gaseous state, and it is gaseous state then to have liquid phase-change in evaporator.
It is worth understanding, " condenser " described here can refer to that high temperature, the cooling medium of high pressure are mutually changed into liquid hair from gaseous state
The heat exchanger of raw condensation heat, for example, in cooling mode, First Heat Exchanger 30 is condenser；And in a heating mode, second
Heat exchanger 40 is condenser.Similarly, " evaporator " can refer to that the heat exchanger of evaporation endothermic, example occur for low-temperature cooling media
Such as, in cooling mode, the second heat exchanger 40 is evaporator；And in a heating mode, First Heat Exchanger 30 is evaporator.
Because the spatial volume that the cooling medium of different phase takes is different, in correlation technique, in order to improve air-conditioning system
Service behaviour, by the volume of first outdoor heat exchanger be more than indoor second heat exchanger volume.However, because air conditioner is in system
Chill formula is different with the flow direction of the cooling medium under heating mode, in cooling mode, and First Heat Exchanger can be as cold
The function of condenser is used, and the second heat exchanger is used as the function of evaporator；And when in a heating mode, indoor second heat exchanger
As the effect of condenser, first outdoor heat exchanger is then as the effect of evaporator.Thus, individually by first outdoor heat exchanger
Volume is more than the design of the volume of indoor second heat exchanger, it is impossible to meet air-conditioning system cooling medium under different working modes
Proper Match, causes air-conditioning system to reach optimal working effect.
As shown in figure 1, by setting liquid storage branch road 60, when air-conditioning system 100 in cooling mode, liquid storage branch road 60 breaks
Open, now, the volume of First Heat Exchanger 30 is more than the volume of the second heat exchanger 40, and air-conditioning system 100 is in the shape that preferably works
State；And when air-conditioning system 100 is switched under heating mode from refrigeration mode, liquid storage branch road 60 is connected, cooling medium can with
It is fitted in liquid storage cylinder 610.Thus, expanded the volume at the second heat exchanger 40, so that it is different to have adjusted air-conditioning system 100
Matching problem of the cooling medium in the heat exchanger 40 of First Heat Exchanger 30 and second, thus, makes air-conditioning system 100 under mode of operation
All there is preferably running status under different mode of operations.
