Referring to figs. 1 through Fig. 3, air-conditioning system one embodiment of the present utility model comprises compressor 1, First Heat Exchanger 4 (outdoor heat converter), the second heat exchanger 2 (indoor heat converter) and first throttle device 8, the first magnetic valve 5, the second magnetic valve 6, check valve 7 and gas-liquid separator 9, compressor 1, First Heat Exchanger 4, first throttle device 8, the second heat exchanger 2 and gas-liquid separator 9 are connected to form refrigerating circuit in turn, compressor 1 comprises upper cylinder and lower cylinder, the first magnetic valve 5 is connected between the exhaust outlet of compressor 1 and the suction end of described lower cylinder, the second magnetic valve 6 is connected between the entrance of gas-liquid separator 9 and the suction end of described lower cylinder, described check valve 7 is connected between first outlet and the suction end of described lower cylinder of described gas-liquid separator 9, described check valve 7 opening directions are downward, the second outlet of described gas-liquid separator 9 is communicated with the suction end of described upper cylinder.Wherein, compressor 1 is frequency conversion positive displacement compressor.Check valve 7 comprises valve seat 71 and spool 72, and spool 72 is placed in the cavity of valve seat 71, and spool 72 relatively valve seat 71 moves up and down, and when spool 72 is placed in the upper end of described cavity, check valve 7 is in closed condition.The opening direction of check valve 7 is downward, and without closing suction, due to self gravitation effect, spool 72 drops on valve seat 71, and check valve 7 is in opening, and refrigerant is realized circulation, and as shown in Figure 2, in figure, the direction of arrow represents that refrigerant flows to; When the bottom of check valve 7 is high pressure refrigerant, refrigerant is pushed into spool 72 upper end (top seal mouth) of the described cavity in valve seat 71, and check valve 7 is in cut-off state, and refrigerant can not circulate, as shown in Figure 3.Spool 72 is when opening like this, gaseous coolant flows to identical with spool 72 gravity directions when air-breathing, check valve is opened without the gravity that overcomes spool 72, even the existence due to compressor frequency, air-breathing is intermittent, check valve two ends air pressure can change by generating period, also can not cause the reciprocating motion of spool 72.There will not be reciprocating motion, also just can not produce the situation of noise and damage spool.
Preferably, between the second magnetic valve 6 and the entrance of gas-liquid separator 9, be also in series with the second throttling arrangement 10, the second magnetic valve 6 is when opening, and the refrigerant of the second 10 pairs of throttling arrangements through the second magnetic valve 6 carries out reducing pressure by regulating flow, thus the pressure at balance check valve two ends Shang Xia 7.
As a kind of embodiment, air-conditioning system is also provided with cross valve 3, cross valve 3 is connected in the refrigerating circuit of air-conditioning system, cross valve 3 has first to fourth valve port, the first valve port D is connected to the exhaust outlet of compressor 1, the second valve port E is connected to the entrance that First Heat Exchanger 4, the three valve port S are connected to gas-liquid separator 9, and the 4th valve port C is connected to the second heat exchanger 2.Cross valve 3 is set, makes air-conditioning system can carry out the switching of refrigeration mode and heating mode; Air-conditioning system when refrigeration mode, the first valve port D and the second valve port E conducting, the 3rd valve port S and the 4th valve port C conducting; Air-conditioning system when heating mode, the first valve port D and the 4th valve port C conducting, the second valve port E and the 3rd valve port S conducting.
The air-conditioning system of above embodiment has single cylinder operational mode and twin-tub operational mode, specific as follows:
(1) single cylinder operational mode
Under single cylinder operational mode, the first magnetic valve 5 is opened, the second electromagnetism 6 is closed, high pressure refrigerant flows to the suction end of lower suction cylinder through the first magnetic valve 5, now the bottom of check valve 7 is high pressure, the top of check valve 7 is low pressure, and check valve 7 is cut-off state, and the gaseous coolant in gas-liquid separator 9 cannot enter the lower cylinder of compressor 1.And the suction end of the lower cylinder of compressor 1 is provided with pressure protective device conventionally, stop high pressure refrigerant to enter in lower cylinder and compress, thereby only have upper cylinder work, and lower cylinder quits work, now compressor 1 is single cylinder operation.
(2) twin-tub operational mode
Under twin-tub operational mode, the first magnetic valve 5 cuts out, the second magnetic valve 6 is opened, low pressure refrigerant flows to the lower cylinder suction end of compressor through the second magnetic valve 6, now the bottom of check valve 7 and top are low pressure, spool 72 is displaced downwardly to the lower end of valve seat 71 in the effect of self gravitation, check valve 7 is conducting state, refrigerant in gas-liquid separator 9 is respectively from the first outlet and the second outlet effluent gases liquid/gas separator 9, the refrigerant flowing out from the first outlet enters the lower cylinder of compressor 1 after check valve 7, the refrigerant flowing out from the second outlet enters the upper cylinder of compressor 1, thereby upper cylinder and the lower cylinder of compressor 1 are all worked, now compressor 1 is twin-tub operation, when check valve 7 is opened (conducting), compressor is after twin-tub running status, the second magnetic valve 6 cuts out.
The air-conditioning system of above-described embodiment, by the cooperation of check valve and magnetic valve, realizes the switching between compressor list twin-tub, thereby has realized the transfiguration of compressor.The opening direction of check valve is downward, and need not close suction, when twin-tub moves, due to Action of Gravity Field, spool drops on valve seat, check valve is in opening, refrigerant is realized circulation, and gaseous coolant flows to identically with spool 72 gravity directions when air-breathing, and check valve is opened without the gravity that overcomes spool 72, even the existence due to compressor frequency, air-breathing is intermittent, and check valve two ends air pressure can change by generating period, also can not cause the reciprocating motion of spool 72.When single cylinder moves, because check valve bottom is high pressure refrigerant, spool is pushed into top seal mouth, check valve is in cut-off state, and refrigerant can not circulate.Spool is only subject to the Action of Gravity Field of spool when opening like this, there will not be reciprocating motion, also can not produce noise and damage spool.
The above embodiment has only expressed several embodiment of the present utility model, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model the scope of the claims.It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection domain of the present utility model.Therefore, the protection domain of the utility model patent should be as the criterion with claims.
