External heat exchanger 4, and energy exchange is carried out with external environment in outdoor heat exchanger 4, the refrigerant in outdoor heat exchanger 4 is through the 8th valve
The valve port 217 of mouth 208 and the 7th, flows into automatically controlled heat exchanger 5, in order to be radiated to electric control element, subsequent refrigerant changes from automatically controlled
Hot device 5 flows out, and enters flash vessel 6, and the refrigerant into flash vessel 6 is separated into two-way (such as refrigerant can be by second interface 62
Into flash vessel 6)：The first via：Liquid refrigerants flows out from first interface 61, and then refrigerant is by the reducing pressure by regulating flow of throttling arrangement 7
Low temperature, the refrigerant after throttling flow into indoor heat exchanger 3 again via the 5th valve port 215 and the 6th valve port 216 again
Row heat absorption, the gaseous coolant of low-temp low-pressure is flashed to, so as to reduce indoor temperature.Gaseous coolant is finally through the He of the 3rd valve port 213
4th valve port 214 returns to the gas returning port 12 of compressor 1, is compressed into high temperature and high pressure gas afterwards and is discharged into next round circulation；
Second tunnel：Flowed out by the gas part separated in flash vessel 6 by the 3rd interface 63, gaseous coolant is sprayed by gas supplementing opening 13
Enter and be compressed in compressor 1, to improve the refrigeration performance of air-conditioning system 100, discharged after compression, into subsequent cycle.
Reference picture 2, when air-conditioning system 100 is in heating mode, the refrigerant of the HTHP after the compression of compressor 1 is through pressure
The exhaust outlet 11 of contracting machine 1, the first valve port 211 and the 3rd valve port 213 for flowing through reversing valve assembly 2 enter indoor heat exchanger 3, and
Exchanged heat indoors in heat exchanger 3 with indoor environment, absorb the cold of indoor environment, the refrigerant after heat exchange is via the 6th valve port 216
Automatically controlled heat exchanger 5 is flowed into the 7th valve port 217, flash vessel 6 is entered back into after heat exchange and is divided into two-way (refrigerant can be connect by second
Mouth 62 enters flash vessel 6)：The first via：Liquid refrigerants flows out from first interface 61, after the reducing pressure by regulating flow of throttling arrangement 7, passes through
Five valve ports 215 and the 8th valve port 208 flow to the heat in outdoor heat exchanger 4 outside absorption chamber, and refrigerant is after the outflow of outdoor heat exchanger 4
Compressor 1 is returned to by the second valve port 212 and the 4th valve port 214, and by the gas returning port 12 of compressor 1, is compressed afterwards
Next round circulation is discharged into high temperature and high pressure gas；Second tunnel：By the gas part separated in flash vessel 6 by the 3rd
Interface 63 is flowed out, and gaseous coolant is sprayed into compressor 1 by gas supplementing opening 13 and is compressed, to improve the heating of air-conditioning system 100 property
Energy.So far the course of work of the air-conditioning system 100 according to the utility model embodiment is completed.
