The present invention proposes a kind of air conditioning system。
Such as the structural representation that Fig. 1 to Fig. 6, Fig. 1 are air conditioning system one embodiment of the present invention；Fig. 2 is the structural representation of air conditioning system one embodiment the first embodiment of the present invention；Fig. 3 is the structural representation of air conditioning system one embodiment the second embodiment of the present invention；Fig. 4 is the structural representation of air conditioning system one embodiment the 3rd embodiment of the present invention；Fig. 5 is the structural representation of air conditioning system one embodiment the 4th embodiment of the present invention；Fig. 6 is the structural representation of another embodiment of air conditioning system of the present invention。
With reference first to Fig. 1, in one embodiment, this air conditioning system includes being sequentially communicated to be formed the compressor 10 of refrigerant circulation circuit, cross valve 20, indoor heat exchanger 30, throttling arrangement 40 and outdoor heat exchanger 50, and namely above-mentioned five parts (compressor 10, cross valve 20, indoor heat exchanger 30, throttling arrangement 40 and outdoor heat exchanger 50) constitute basic air conditioning system。The air conditioning system of the present embodiment also includes flash vessel 60, gas-liquid separator 70 and the first pipeline assembly 80, flash vessel 60 is serially connected on the liquid refrigerants pipeline section at throttling arrangement 40 place, the puff prot 61 of flash vessel 60 connects the inlet 71 of gas-liquid separator 70, the gas outlet 72 of gas-liquid separator 70 connects the gas supplementing opening 11 of compressor 10, the liquid outlet 73 of gas-liquid separator 70 is through liquid refrigerants pipeline section (the non-label of the first pipeline assembly 80 unilaterally connected to throttling arrangement 40 place, namely outdoor heat exchanger 50 is communicated to the coolant pipeline section of indoor heat exchanger 30 through throttling arrangement 40), namely the liquid refrigerants in gas-liquid separator 70 can flow out in liquid refrigerants pipeline section through described first pipeline assembly 80 from its liquid outlet 73, and the coolant in liquid refrigerants pipeline section can not in the first pipeline assembly 80 adverse current to gas-liquid separator 70。
The air conditioning system of the present embodiment is operationally, coolant circulates in refrigerant circulation circuit, liquid refrigerants in liquid refrigerants pipeline section flows into flash vessel 60 from one end of flash vessel 60, liquid refrigerants carries out first time gas-liquid separation in flash vessel 60, isolate the gaseous coolant of remaining in liquid refrigerants, liquid refrigerants after separation flow back into liquid refrigerants pipeline section from the other end of flash vessel 60, isolated gaseous coolant then sprays from the puff prot 61 of flash vessel 60, the gaseous coolant of flash vessel 60 puff prot 61 ejection enters into gas-liquid separator 70 from the inlet 71 of gas-liquid separator 70；Enter into the secondary gas-liquid separation then through gas-liquid separator 70 of the gaseous coolant in gas-liquid separator 70, a small amount of liquid refrigerants of remaining in gaseous coolant is separated, gaseous coolant after secondary gas-liquid separation is discharged to compressor 10 from the gas outlet 72 of gas-liquid separator 70 and carries out QI invigorating, stays the liquid refrigerants in gas-liquid separator 70 and then flow back into the liquid refrigerants pipeline section at throttling arrangement 40 place from its liquid outlet 73。
Owing to the liquid outlet 73 of gas-liquid separator 70 is the liquid refrigerants pipeline section through the first pipeline assembly 80 unilaterally connected to throttling arrangement 40 place, first pipeline assembly 80 is intended on the direction that liquid outlet 73 flows outwardly to turn on, namely liquid outlet 73 can only go out liquid through the first pipeline assembly 80, and can not reversely flow back towards liquid；Therefore, the liquid refrigerants in liquid refrigerants pipeline section will not reversely flow back towards gas-liquid separator 70 from the first pipeline assembly 80。
Liquid refrigerants in liquid refrigerants pipeline section is carried out first time separation by adopting by flash vessel 60 by the technical scheme of the present embodiment, adopt gas-liquid separator 70 that the gaseous coolant separated in flash vessel 60 is carried out secondary gas-liquid separation after isolating gaseous coolant again, the gaseous coolant obtained after secondary gas-liquid separation is sent into the gas supplementing opening 11 of compressor 10, to compressor 10 QI invigorating, improve air conditioning system refrigeration or the efficiency heated；It is that isolated gaseous coolant obtains then through the secondary gas-liquid separation of gas-liquid separator 70 from flash vessel 60 owing to sending into the gaseous coolant of gas supplementing opening 11, therefore in the gaseous coolant of the gas supplementing opening 11 of feeding compressor 10, the amount containing liquid refrigerants is few, will not make compressor 10 that liquid occurs back, improve the safety that compressor 10 runs, thus having ensured the reliability that air conditioning system is properly functioning；And, gas-liquid separator 70 separates the liquid refrigerants stayed and flow back into liquid refrigerants pipeline section from the first pipeline assembly 80, make the coolant quantity in air conditioning system to reduce, prevent that again gas-liquid separator 70 accumulates too much coolant and cause 72 times, the gas outlet liquid of gas-liquid separator 70。
