The refrigerant does not freeze in winter. Such a setting can ensure that the air-conditioning system can operate normally in the cold winter.
[0026] Furthermore, the indoor heat exchanger 1 includes an indoor surface cooler 6 and an indoor fan 7 , and the outdoor heat exchanger 2 includes an outdoor surface cooler 8 and an outdoor fan 9 .
[0027] Further, the pipeline includes a first connecting pipe 10, a second connecting pipe 11, a third connecting pipe 12, a fourth connecting pipe 13, a fifth connecting pipe 14 and a sixth connecting pipe 15; and the valve includes a first valve 16, a second valve 17, a third valve 18 and a fourth valve 19. The underground heat exchanger 3, the first connecting pipe 10, the second connecting pipe 11, the outdoor heat exchanger 2, the third connecting pipe 12, the fourth connecting pipe 13 and the underground heat exchanger 3 are sequentially connected to form a first circulation passage for refrigerant circulation, the first valve 16 is arranged on the second connecting pipe 11, and the third valve 18 is arranged on the third connecting pipe 12.

[0031] The operating modes of the air conditioning system are:
[0032] Winter operation mode: close the second valve 17 and the fourth valve 19 (the indoor heat exchanger 1 does not work in winter), and open the first valve 16 and the third valve 18. When the outdoor temperature is lower than 5°C, start the refrigerant pump 5 and the outdoor fan 9 of the outdoor heat exchanger 2. The refrigerant pump 5 draws the refrigerant in the liquid reservoir 4 and starts to circulate in the first circulation path. The refrigerant enters the outdoor surface cooler 8 in the outdoor heat exchanger 2. The low-temperature outdoor air passes over the fin surface of the outdoor surface cooler 8 under the action of the outdoor fan 9, and transfers the cold energy to the refrigerant in the first circulation path through the fins. After the refrigerant is cooled, it enters the liquid distributor 22 of the underground heat exchanger 3 through the third connecting pipe 12 and the fourth connecting pipe 13. The liquid distributor 22 diverts the refrigerant into several heat exchange tubes 20. The refrigerant carries the cold energy through the wall of the heat exchange tube 20 to the soil around the underground heat exchanger 3 to realize cold storage. After the heat exchange in the underground heat exchanger 3 is completed, the refrigerant enters the liquid reservoir 4 and is transferred to the next cycle through the refrigerant pump 5.

[0033] Summer operation mode: close the first valve 16 and the third valve 18 (the outdoor heat exchanger 2 does not work in summer), open the second valve 17 and the fourth valve 19. When the indoor air conditioning is needed to cool down, start the refrigerant pump 5 and the indoor fan 7 of the indoor heat exchanger 1, the refrigerant pump 5 extracts the refrigerant in the liquid storage tank 4 and starts to circulate in the second circulation path, the refrigerant pump 5 drives the low-temperature liquid phase refrigerant circulation to make the refrigerant enter the indoor surface cooler 6 in the indoor heat exchanger 1, and the indoor high-temperature air passes over the fin surface of the indoor surface cooler 6 under the action of the indoor fan 7. The low-temperature refrigerant in the second circulation path transfers the cold to the indoor high-temperature air through the fins, so that the indoor air temperature is reduced, and the air conditioning cooling effect is achieved. The refrigerant absorbs heat in the indoor heat exchanger 1 and changes phase. The refrigerant absorbs heat in the air and becomes a gas phase refrigerant and enters the underground heat exchanger 3 through the sixth connecting pipe 15 and the fourth connecting pipe 13. The gas phase refrigerant condenses into a liquid phase when it encounters cold in the underground heat exchanger 3, and then enters the liquid storage tank 4 and the next cycle through the refrigerant pump 5. This process repeats itself to achieve cooling of the air-conditioned room.
