The heat exchanger body 1 of the present invention includes two heat exchange tube assemblies arranged at intervals in a direction perpendicular to a predetermined direction, and a plurality of heat exchange tubes 10 arranged at intervals in sequence in the predetermined direction for each heat exchange tube assembly.

In this way, when the heat exchanger assembly 300 is used for refrigerating, the amount of liquid refrigerant participating in heat exchange in the later stage of heat exchange can be reduced, and when the heat exchanger assembly 300 is used for heating, the amount of gaseous refrigerant participating in heat exchange in the later stage of heat exchange can be reduced, so that the heat exchanger assembly 300 is different in the content of the refrigerant in the heat exchanger assembly 300 when the heat exchange and the refrigeration are realized, and the heat exchange effect of the heat exchanger assembly 300 is improved.

As shown in fig. 4 to 6, the present invention further provides an air conditioning system, which includes a compressor 100, a four-way valve 200, a heat exchanger assembly 300, a throttling part 400, an outdoor unit 600 and an indoor unit 500, wherein the compressor 100, the four-way valve 200, the heat exchanger assembly 300 and the throttling part 400 are all positioned in the outdoor unit 600, the compressor 100 is connected with the four-way valve 200, and heat exchange flow paths in the four-way valve 200, the heat exchanger assembly 300, the throttling part 400 and the indoor unit 500 are sequentially connected end to end; the heat exchanger assembly 300 is the heat exchanger assembly described above.

(1) When the air conditioning system is in heating mode

As shown in fig. 2 and 5, the outdoor heat exchanger (i.e., the heat exchanger assembly 300 of the present invention) works as an evaporator, and the two-phase refrigerant (the dryness of the refrigerant at this time is about 0.2) flowing out from the compressor 100 after passing through the four-way valve 200, the heat exchange flow path in the indoor unit 500 and the throttling part 400 enters the first heat exchange pipeline 11 through the second inlet and outlet pipeline 3 for heat exchange, the heat exchange coefficient of the refrigerant increases with the dryness in the process, and after reaching a certain degree, the heat exchange coefficient of the refrigerant decreases rapidly, that is, the heat exchange in the first heat exchange pipeline 11 is efficiently performed; the liquid refrigerant and a part of the gaseous refrigerant are divided into four paths by the liquid collecting pipe assembly 5 and respectively enter the two second heat exchange pipelines 12 and the two third heat exchange pipelines 13, finally return to the compressor 100 through the gas distributing pipe assembly 4, the first inlet and outlet pipeline 2 and the four-way valve 200, enter the compressor 100 for circulation, and the other part of the gaseous refrigerant is stored in the communication pipeline between the second control valve 8 and the third flow divider 52.

In the evaporation process, excessive gaseous refrigerant can cause deterioration of evaporation heat transfer, so that a part of gaseous refrigerant needs to be stored to reduce dryness of the refrigerant, so that the subsequent four-way refrigerant can also perform efficient heat exchange in the two second heat exchange pipelines 12 and the two third heat exchange pipelines 13.

In addition, in the subsequent heat exchange process, the gaseous refrigerant is more and more, because the flow velocity of the gaseous refrigerant is higher and the resistance is larger, the resistance of the gaseous refrigerant can be reduced by dividing the gaseous refrigerant into four paths, the heat exchange efficiency is further improved, and because the evaporator is very sensitive to the pressure drop, the number of the heat exchange pipelines such as the second heat exchange pipeline 12 and the third heat exchange pipeline 13 is more and better.

(2) When the air conditioning system is in the cooling mode

As shown in fig. 3 and 6, the outdoor heat exchanger (i.e., the heat exchanger assembly 300 of the present invention) works as a condenser, and the gaseous refrigerant coming out of the compressor 100 enters the heat exchanger assembly through the four-way valve 200, the heat exchange flow path in the indoor unit 500 and the throttling part 400, then enters the heat exchanger assembly through the first inlet and outlet pipeline 2 of the heat exchanger assembly, firstly passes through the gas distribution pipe assembly 4, then is divided into two paths through the second splitter 44 (such as a Y-shaped three-way splitter) to enter the two third heat exchange pipelines 13 respectively for condensation heat exchange, and the two-phase refrigerant after heat exchange enters the liquid collecting pipe assembly 5, and the refrigerant in the gas distribution pipe assembly 4 cannot enter the two second heat exchange pipelines 12 through the first splitter 42 due to the blocking of the first control valve 7; a part of the liquid refrigerant in the cold coal entering the header assembly 5 is gathered in the communication pipeline between the third diverter 52 and the third control valve 9 and does not participate in circulation, the rest of the refrigerant in the cold coal entering the header assembly 5 enters the two second heat exchange pipelines 12, is gathered through the first diverter 42, enters the first heat exchange pipeline 11 through the second control valve 8 for heat exchange, and finally returns to the compressor 100 through the second inlet and outlet pipeline 3, the throttling part 400, the heat exchange flow path in the indoor unit 500 and the four-way valve 200.

Since the liquid refrigerant in the condensation process forms a liquid film on the heat exchange pipeline when too much liquid refrigerant is used to increase the thermal resistance during heat transfer and further affect the heat exchange effect, a part of the liquid refrigerant needs to be converged between the third diverter 52 and the third control valve 9. The liquid refrigerant quantity in the same space is larger than the gaseous refrigerant quantity, so the refrigerant quantity in the refrigerating process is smaller than the refrigerant quantity in the heating process, and the purposes of different requirements of heating and refrigerating on the refrigerant quantity are also achieved.

In addition, the resistance, pressure drop and flow rate of the gaseous refrigerant from the compressor 100 are all large, if the flow is divided into four paths, the total length of the heat exchange lines is short, the flow rate is also small although the resistance is reduced, and the sensitivity of the condenser to the pressure drop is low, so that the heat exchange amount of the small flow paths is large, and the heat exchange amount which can be achieved by first moving the two third heat exchange lines 13 and then moving the two second heat exchange lines 12 is large, so that the heat exchange effect is good.
