It should be noted that in the disclosure, the refrigeration of air-conditioning system itself is barely affected, this is because refrigerator steams It is smaller to send out the volume of device, and air-conditioning system is the critical component for heating and freezing：Indoor condenser and indoor evaporator Volume it is relatively large, the physical change of refrigerant and the heat absorption of refrigerant and heat release are mainly completed in both parts 's.

As described above, in the disclosure, expansion switch valve is the valve for having the function of simultaneously expansion valve and switch valve function, It is the integrated of switch valve and expansion valve that can be regarded as.It will be provided below a kind of example embodiment party for expanding switch valve Formula.

As shown in figure 11, expansion switch valve mentioned above can include valve body 500, wherein, it is formed on the valve body 500 Import 501, outlet 502 and connection are in import 501 and export the inner flow passage between 502, and first is equipped on inner flow passage 503 and second spool 504 of spool, the first spool 503 is so that import 501 directly connects or disconnect connection, the second valve with outlet 502 Core 504 is so that import 501 is connected or disconnected connection by restriction 505 with outlet 502.

Wherein, " directly connection " that the first spool is realized refers to can be with from the cooling agent of the entrance of import 501 of valve body 500 It crosses the first spool and the outlet 502 of valve body 500 is insusceptibly flowed directly to by inner flow passage, what the first spool was realized " disconnecting connection " refers to that the cooling agent from the entrance of import 501 of valve body 500 can not cross the first spool and cannot pass through inside stream Road flows to the outlet 502 of valve body 500." being connected by restriction " that second spool is realized refers to the import 501 from valve body 500 Flow to the outlet 502 of valve body 500 after the throttling that the cooling agent of entrance can cross the second spool and pass through restriction, and the second valve " disconnect connection " that core is realized refer to the cooling agent from the entrance of import 501 of valve body 500 can not cross the second spool and cannot The outlet 502 of valve body 500 is flowed to by restriction 505.

In this way, by the control to the first spool and the second spool, the expansion switch valve of the disclosure can cause from import 501 cooling agents entered at least realize three kinds of states.That is, 1) cut-off state；2) the direct connected state of the first spool 503 is crossed State；And 3) cross the throttling mode of communicating of the second spool 504.

Wherein, after the liquid refrigerant of high temperature and pressure throttles using restriction 505, the vaporific of low-temp low-pressure can be become Hydraulic pressure refrigerant, can be refrigerant evaporation create conditions, i.e., the cross-sectional area of restriction 505 be less than export 504 horizontal stroke Sectional area, and by controlling the second spool, the aperture size of restriction 505 can be adjusted, and restriction 505 is flowed through with control Flow is prevented because the refrigeration of the very few generation of refrigerant is insufficient and prevents from due to refrigerant is excessive compressor being caused to generate liquid hammer Phenomenon.That is, the cooperation of the second spool 504 and valve body 500 can so that expanding pass valve has the function of expansion valve.
