Fig. 3 and Fig. 4 are referred to, in some embodiments, air-conditioning system 200 also includes automatically controlled heat exchanger 290, automatically controlled to change
Hot device 290 is used to exchange heat to the electric-controlled parts of air-conditioning system 200, and automatically controlled heat exchanger 290 is connected to first throttle element 250 and sudden strain of a muscle
Between steaming device 100.Or automatically controlled heat exchanger 290 is connected between the second restricting element 260 and flash vessel 100.
Specifically, the electric-controlled parts of air-conditioning system 200 include frequency converter, and electric-controlled parts can be used for changing the work of compressor 210
The frequency of work, the rotating speed of cooling fan etc., electric-controlled parts can produce substantial amounts of heat at work and temperature rises, electric-controlled parts
Temperature is too high to reduce the precision of electric-controlled parts control, or even can increase the risk that electric-controlled parts catch fire etc..Automatically controlled heat exchanger
290 by transmitting refrigerant and so that refrigerant undergoes phase transition and absorbed heat in automatically controlled heat exchanger 290, to reduce the temperature of electric-controlled parts
Degree, improves the stability of electric-controlled parts work.
In this way, when no matter air-conditioning system 200 is operated in kind of refrigeration cycle or heats circulation, by the cold of automatically controlled heat exchanger 290
The temperature that matchmaker only passes through in a restricting element (restricting element 260 of first throttle element 250 or second), automatically controlled heat exchanger 290
Degree can be effectively prevented from forming condensed water on the surface of automatically controlled heat exchanger 290 all without too low.
So that automatically controlled heat exchanger 290 is arranged between first throttle element 250 and flash vessel 100 as an example, when air-conditioning system 200
When being operated in kind of refrigeration cycle, the flow direction of refrigerant is as follows：The HTHP refrigerant discharged from the exhaust outlet 212 of compressor 210 is through changing
Enter in outdoor heat exchanger 230 and condense to the first valve port 221 and the second valve port 222 of component 220, refrigerant is in outdoor heat exchanger
Discharged after being exchanged heat in 230 with outdoor environment from the second port 232 of outdoor heat exchanger 230.The liquid phase refrigerant being then discharged out
By the reducing pressure by regulating flow of first throttle element 250, the refrigerant after throttling passes through automatically controlled heat exchanger 290, by automatically controlled heat exchanger 290
Gas-liquid two-phase refrigerant enter flash vessel 100 from the first refrigerant mouthfuls 21, and carry out in flash vessel 100 gas-liquid separation.From flash distillation
The gaseous coolant isolated in device 100 flows through gas supplementing opening 213 from gas outlet 41 and returned in compressor 210, from pressure after overcompression
The discharge of exhaust outlet 212 of contracting machine 210 proceeds circulation.The liquid refrigerants isolated from flash vessel 100 flows from refrigerant mouthful 33
Go out, then refrigerant is entered in indoor heat exchanger 240 after the reducing pressure by regulating flow of the second restricting element 260.Refrigerant is changed indoors
Heat exchange is carried out with indoor environment in hot device 240 to undergo phase transition, and indoor environment is freezed, discharged from indoor heat exchanger 240
Gas phase refrigerant by the 3rd valve port 223 and the 4th valve port 224 of commutation component 220, then inhale from the first air entry 211 and second
Gas port 214 enters in compressor 210, completes kind of refrigeration cycle.
So that automatically controlled heat exchanger 290 is arranged between first throttle element 250 and flash vessel 100 as an example, when air-conditioning system 200
It is operated in when heating circulation, the flow direction of refrigerant is as follows：The high pressure gaseous refrigerant discharged from the exhaust outlet 212 of compressor 210,
Got in by the first valve port 221 and the 3rd valve port 223 for the component 220 that commutates in heat exchanger 240, in indoor heat exchanger 240
Refrigerant and the indoor environment of HTHP carry out phase-change heat-exchange, to be heated to indoor environment.From the row of indoor heat exchanger 240
The liquid phase refrigerant gone out carries out first time throttling by the second restricting element 260, and the refrigerant after throttling passes through automatically controlled heat exchanger 290,
Entered by the gas-liquid two-phase mixing refrigerant of automatically controlled heat exchanger 290 in flash vessel 100, flash vessel 100 carries out gas-liquid to refrigerant
Separation.The gaseous coolant isolated from flash vessel 100 flows through gas supplementing opening 213 from gas outlet 41 and returned in compressor 210, through pressure
Proceed circulation from the discharge of exhaust outlet 212 of compressor 210 after contracting.The liquid refrigerants isolated from flash vessel 100 is from cold
Matchmaker mouthful 21 is flowed out, and is entered after being depressured through the second throttle of first throttle element 250 in outdoor heat exchanger 230, outdoor heat exchanger 230
In refrigerant evaporation heat exchange after, through commutation component 220 the second valve port 222 and the 4th valve port 224, from the first air entry
211 and second air entry 214 enter compressor 210 in, completion heat circulation.
