Below with reference to Fig. 1, describe according to the air-conditioner 100 of the utility model embodiment, this air-conditioner 100 can freeze and also can heat.
As shown in Figure 1, according to the air-conditioner 100 of the utility model embodiment, comprise: compressor 1, cross valve 5, indoor heat exchanger 3, outdoor heat exchanger 2, gas-liquid separator 4, first throttle element C1, second section fluid element C2, the 3rd restricting element C3 and the 4th restricting element C4.
Gas-liquid separator 4 has import 4h, liquid outlet 4l and gas vent 4g, import 4h is connected by first passage 6 with the other end of indoor heat exchanger 3, liquid outlet 4l is connected by second channel 7 with the other end of indoor heat exchanger 3, import 4h is connected by third channel 8 with the other end of outdoor heat exchanger 2, liquid outlet 4l is connected by four-way 9 with the other end of outdoor heat exchanger 2, gas vent 4g is connected by Five-channel 10 with puff prot 1i, and gas vent 4g is connected by the 6th passage 11 with indoor heat exchanger interface 5c.
First throttle element C1 is located on first passage 6.Second section fluid element C2 is located on third channel 8.The 3rd restricting element C3 is located on four-way 9.The 4th restricting element C4 is located on the 6th passage 11.Alternatively, first throttle element C1, second section fluid element C2, the 3rd restricting element C3 and the 4th restricting element C4 are respectively capillary or magnetic valve etc.
When air-conditioner 100 carries out heating operation, the now air-breathing interface 5a of cross valve 5 and outdoor heat exchanger interface 5d conducting, exhaust port 5b and indoor heat exchanger interface 5c conducting, the refrigerant of discharging from exhaust outlet 1d enters in indoor heat exchanger 3 by exhaust port 5b and indoor heat exchanger interface 5c successively, the refrigerant of discharging from indoor heat exchanger 3 enters in first passage 6 and from import 4h, is drained in gas-liquid separator 4 after first throttle element C1 reducing pressure by regulating flow, and the refrigerant entering in gas-liquid separator 4 carries out gas-liquid separation.Owing to first passing through first throttle element C1 reducing pressure by regulating flow, the refrigerant pressure at gas vent 4g place is lower than the pressure of indoor heat exchanger interface 5c, now the 6th passage 11 between gas vent 4g and indoor heat exchanger interface 5c is in not on-state, thereby the gas coolant of separating is drained in Five-channel 10 by gas vent 4g, last gas coolant is ejected in compressor 1 by puff prot 1i.The liquid refrigerants of simultaneously separating is drained in four-way 9 by liquid outlet 4l, then liquid refrigerants is drained in outdoor heat exchanger 2 after the 3rd restricting element C3 reducing pressure by regulating flow, from outdoor heat exchanger 2, discharge refrigerant and by outdoor heat exchanger interface 5d, air-breathing interface 5a and air entry 1s, be expelled back in compressor 1 successively, thereby complete, heat circulation.
