It is described in detail in below with reference to Fig. 2-Fig. 6 under different mode of operations, the stream of the refrigerant in refrigeration system 100
Road.
As shown in Fig. 2 when refrigeration system 100 is in the mode of operation of the separate refrigeration of air-conditioning heat exchanger 3：
According to the arrow in Fig. 2 and shown in solid, exhaust outlet 11 corresponding to compressor 1 passes through pipeline and connects the first triple valve
51, under air-conditioning separate refrigeration operational mode, refrigerant flows out to enter through the first triple valve 51, the first outdoor port 21 from exhaust outlet 11
Enter to outdoor heat exchanger 2, condenser of the outdoor heat exchanger 2 as system, the gas of HTHP is cooled down, form supercooling
High pressure refrigerant liquid, the refrigerant liquid of high pressure supercooling is after the discharge of second Room external port 22, by the first electric expansion valve 61,
Now the first electric expansion valve 61 is in the conduction state, does not carry out throttling processing to refrigerant, wherein now can be by by second
Electric expansion valve 62 completely closes (now the second electric expansion valve 62 is in and blocks state), or can control the 6th triple valve
56 blocked with the valve port of the second electric expansion valve 62, makes the refrigerant by the 6th triple valve 56 only flow to air-conditioning heat exchanger 3.
First (now the 3rd electronics is depressured from the refrigerant of the 6th triple valve 56 outflow by the 3rd electric expansion valve 63
Expansion valve 63 is in throttle), have part cold media gas shwoot and come out, this part gas-liquid mixture is through the second air-conditioning port
32 enter in air-conditioning heat exchanger 3, evaporator of the air-conditioning heat exchanger 3 as system, and in air-conditioning heat exchanger 3, refrigerant absorbs heat
As low area overheat gas, after being discharged from the first air-conditioning port 31, a part of refrigerant passes through the 3rd triple valve 53 and second successively
Triple valve 52 is entered in the first compression chamber from the first air entry 14, and high temperature and high pressure gas are compressed into the first compression chamber,

Air-conditioning port 31 is entered in air-conditioning heat exchanger 3, condenser of the air-conditioning heat exchanger 3 as system, the gas of HTHP is entered
Row cools down, and to indoor releasing heat and is heated, and forms the highly pressurised liquid of supercooling, now the 3rd electric expansion valve 63
It is in the conduction state, do not throttled to flowing through its refrigerant, wherein now can be by the way that the second electric expansion valve 62 is completely closed
(now the second electric expansion valve 62 be in block state), or can control the 6th triple valve 56 with the second electric expansion valve
62 valve port blocks, and the refrigerant by the 6th triple valve 56 is only flowed to outdoor heat exchanger 2.
First (now the first electronics is depressured from the refrigerant of the 6th triple valve 56 outflow by the first electric expansion valve 61
Expansion valve 61 is in throttle), have part cold media gas shwoot and come out, this part gas-liquid mixture is through second Room external port
22 enter in outdoor heat exchanger 2, evaporator of the outdoor heat exchanger 2 as system, and in outdoor heat exchanger 2, refrigerant absorbs heat
As low area overheat gas, after being discharged from the first outdoor port 21, a part of refrigerant passes through the 3rd triple valve 53 and second successively
Triple valve 52 is entered in the first compression chamber from the first air entry 14, and high temperature and high pressure gas are compressed into the first compression chamber,
It is discharged into the housing of compressor 1；Another part refrigerant passes through the 5th triple valve 55 and the 4th triple valve 54 from the second air entry successively
14 are entered in the second compression chamber, and high temperature and high pressure gas are compressed into the second compression chamber, are discharged into the housing of compressor 1, two
After refrigerant in individual compression chamber mixes in the housing of compressor 1, then discharge from exhaust outlet 11, the circulation so to go round and begin again.
In figure 3, many places line employs dotted line, this represents that this part pipeline flows without refrigerant, such as refrigerator evaporation
Pipeline before and after device 4 is dotted line, and this is due to that system completely closes (now the second electric expansion valve of the second electric expansion valve 62
62 in blocking state), or the corresponding valve port of the 6th triple valve 56 is blocked.
As shown in figure 4, when refrigeration system 100 is in the mode of operation of the separate refrigeration of evaporator of refrigerator 4：
According to the arrow in Fig. 4 and shown in solid, exhaust outlet 11 corresponding to compressor 1 passes through pipeline and connects the first triple valve
51, under air-conditioning separate refrigeration operational mode, refrigerant flows out to enter through the first triple valve 51, the first outdoor port 21 from exhaust outlet 11
Enter to outdoor heat exchanger 2, condenser of the outdoor heat exchanger 2 as system, the gas of HTHP is cooled down, form supercooling
High pressure refrigerant liquid, the refrigerant liquid of high pressure supercooling is after the discharge of second Room external port 22, by the first electric expansion valve 61,
