下面以换向组件包括第一并联电磁阀19和第二并联电磁阀20,以及包括其他实施例技术特征的实施例(如图2所示)具体说明热泵空调系统不同工作模式下的工作过程:The working process of the heat pump air-conditioning system in different working modes will be specifically described below with the reversing assembly including the first parallel solenoid valve 19 and the second parallel solenoid valve 20, and an embodiment (as shown in FIG. 2 ) including the technical features of other embodiments:

如图3所示,热泵空调系统的制冷模式:As shown in Figure 3, the cooling mode of the heat pump air conditioning system:

第一并联电磁阀19关闭,第二并联电磁阀20、第三并联电磁阀21和第四并联电磁阀22打开;第一并联电子膨胀阀23和第四并联电子膨胀阀26均关闭,第二并联电子膨胀阀24、第三并联电子膨胀阀25、第五并联电子膨胀阀27和第六并联电子膨胀阀28均打开,鼓风机29打开。压缩机1排出高温高压制冷剂通过第二并联电磁阀20和第二并联电子膨胀阀24流入第三换热器3,此时第二并联电子膨胀阀24全开,制冷剂在第三换热器3内冷凝放热后通过第三并联电子膨胀阀节流分支两路,一路通过第一接口401流入第一换热器4内以吸收空气热量,然后从第二接口402流出;另一路通过第一单向阀13从第四接口502流入第二换热器5内以吸收空气热量后,分别从第三接口501和第五接口503流出,分别经过第五并联电子膨胀阀27、第六并联电子膨胀阀28和第四并联电磁阀22与第二接口402流出的制冷剂汇合一起流入第三并联电磁阀21,然后进入气液分离器2,此时第五并联电子膨胀阀27和第六并联电子膨胀阀28均为全开。制冷剂在气液分离器2中进行气液分离干燥后流入压缩机1,至此完成制冷剂制冷模式循环。鼓风机29吸入空气依次经过第一换热器4,第二换热器5换热后吹入到乘员舱,实现乘员舱制冷。The first parallel solenoid valve 19 is closed, the second parallel solenoid valve 20, the third parallel solenoid valve 21 and the fourth parallel solenoid valve 22 are opened; the first parallel electronic expansion valve 23 and the fourth parallel electronic expansion valve 26 are both closed, and the second The parallel electronic expansion valve 24 , the third parallel electronic expansion valve 25 , the fifth parallel electronic expansion valve 27 and the sixth parallel electronic expansion valve 28 are all turned on, and the blower 29 is turned on. The high-temperature and high-pressure refrigerant discharged from the compressor 1 flows into the third heat exchanger 3 through the second parallel solenoid valve 20 and the second parallel electronic expansion valve 24. After condensing and dissipating heat in the device 3, the throttling branch of the third parallel electronic expansion valve branches into two paths, one path flows into the first heat exchanger 4 through the first interface 401 to absorb air heat, and then flows out from the second interface 402; the other path passes through After the first one-way valve 13 flows into the second heat exchanger 5 from the fourth port 502 to absorb the heat of the air, it flows out from the third port 501 and the fifth port 503 respectively, and passes through the fifth parallel electronic expansion valve 27 and the sixth The parallel electronic expansion valve 28 and the fourth parallel solenoid valve 22 merge with the refrigerant flowing out of the second port 402 to flow into the third parallel solenoid valve 21 and then enter the gas-liquid separator 2.

Other flow modes of heat and refrigerant are the same as the flow process described above, and will not be repeated here.

双温区制冷模式运行时,通过调控第五并联电子膨胀阀27和第六并联电子膨胀阀28开度即可,打开第五并联电子膨胀阀27和第六并联电子膨胀阀28两者中的一个,或者第五并联电子膨胀阀27和第六并联电子膨胀阀28均打开,但是开度不同,即控制流出第二换热器5两芯体内的流量来控制制冷剂与空气的热交换量,制冷剂其它流动方式同高温制冷模式流动过程一致,在此不再赘述。When operating in the cooling mode with dual temperature zones, it is sufficient to adjust the opening degrees of the fifth parallel electronic expansion valve 27 and the sixth parallel electronic expansion valve 28, and open the fifth parallel electronic expansion valve 27 and the sixth parallel electronic expansion valve 28. One, or both the fifth parallel electronic expansion valve 27 and the sixth parallel electronic expansion valve 28 are open, but the opening degrees are different, that is, the flow out of the two cores of the second heat exchanger 5 is controlled to control the amount of heat exchange between the refrigerant and the air , the other flow modes of the refrigerant are consistent with the flow process of the high-temperature refrigeration mode, and will not be repeated here.

Both the fifth parallel electronic expansion valve 27 and the sixth parallel electronic expansion valve 28 can adjust the flow. Adjusting the flow distribution can realize the dual-temperature zone heating of the passenger compartment; the other path passes through the fourth parallel solenoid valve 22, and then flows into the first heat exchanger 4 through the second interface 402 to condense and release heat.
