Next, referring to fig. 2, the operation of the air conditioning system in the present embodiment will be briefly described.

As shown in fig. 2, when the temperature needs to be reduced indoors, the general controller controls the compressor 11, the outer fan 121, the water pump 231, the inner fan 141, the temperature reduction fan 343, and the circulation pump 341 to start, and controls the first electronic control valve 111 to close, the second electronic control valve 352 to open, the second throttling element 351 to fully open, and the first throttling element 13 to open to the set opening. At this time, the cooling liquid in the cooling water tank 21 is sprayed onto the coil of the outdoor heat exchanger 12 by the spraying pipe 23 under the driving of the water pump 231, the circulating pump 341 drives the heat-exchange liquid to circulate between the reduction water tank 33 and the cooling water tank 21, the compressor 11 discharges high-temperature high-pressure gaseous refrigerant, the high-temperature high-pressure gaseous refrigerant enters the reduction water tank 33 through the heat-exchange coil 35 and exchanges heat with the heat-exchange liquid in the reduction water tank 33 and then enters the outdoor heat exchanger 12, the refrigerant entering the outdoor heat exchanger 12 performs double heat exchange with outdoor air and spray water to become medium-temperature high-pressure liquid refrigerant, the medium-temperature high-pressure liquid refrigerant becomes low-temperature low-pressure gas-liquid two-phase refrigerant after being throttled by the first throttling element 13, the low-temperature low-pressure gas-liquid two-phase refrigerant enters the indoor heat exchanger 14 to exchange heat with indoor. Then the low-temperature low-pressure gaseous refrigerant returns to the compressor 11 through the suction port to realize the circulation of the refrigerant.

When dehumidification is needed indoors, the master controller controls the dehumidification fan 315 to start and operate, indoor air enters the dehumidification box 31 from the dehumidification air inlet 311 under the driving of the dehumidification fan 315, moisture in the air is adsorbed on the solid adsorbent to become dry air when passing through the solid adsorption component 32, the dry air returns indoors through the dehumidification air outlet 312, and the indoor humidity is reduced along with the moisture.

When the solid adsorption component 32 adsorbs a certain amount of water and needs to be regenerated, if the refrigeration mode of the air conditioning system is running, that is, the compressor 11, the outer fan 121, the water pump 231, the inner fan 141, the cooling fan 343, and the circulation pump 341 are running, the first electronic control valve 111 is closed, the second electronic control valve 352 is opened, the second throttling element 351 is fully opened, and the first throttling element 13 is opened to a set opening degree, the overall controller continues to control the reduction fan 316 to be started at this time, and the refrigerant enters the dehumidification tank 31 from the reduction air inlet 313 according to the refrigeration cycle, and is discharged to the outside from the reduction air outlet 314. High-temperature and high-pressure gaseous refrigerant discharged from the compressor 11 enters the reduction water tank 33 through the heat exchange coil 35 and heats heat exchange liquid in the reduction water tank 33, the circulating pump 341 drives the heat exchange liquid to circulate between the reduction water tank 33 and the cooling water tank 21, when the heat exchange liquid is heated to a higher temperature and circulates to the solid adsorption component 32, moisture in the solid adsorption component 32 is heated and evaporated by the heat exchange liquid to be water vapor and separated out, the separated water vapor is discharged to the outdoor along with indoor air, and the solid adsorption component 32 realizes regeneration.

If the air conditioning system does not operate in the cooling mode, at this time, the general controller controls the compressor 11, the external fan 121, the water pump 231, the cooling fan 343, the reduction fan 316 and the circulation pump 341 to start, and controls the first electronic control valve 111 to close, the second electronic control valve 352 to open, the second throttling element 351 to open to a certain opening degree, and the first throttling element 13 to fully open, so that the indoor air enters the dehumidification tank 31 from the reduction air inlet 313 and is discharged to the outside from the reduction air outlet 314. The high-temperature high-pressure gaseous refrigerant discharged from the compressor 11 enters the reduction water tank 33 through the heat exchange coil 35, is subjected to heat exchange with the heat exchange liquid in the reduction water tank 33 and then is changed into a medium-temperature high-pressure liquid refrigerant, the medium-temperature high-pressure liquid refrigerant is throttled by the second throttling element 351 and then is changed into a low-temperature low-pressure gas-liquid two-phase refrigerant, the low-temperature low-pressure gas-liquid two-phase refrigerant enters the outdoor heat exchanger 12 to be subjected to heat exchange with outdoor air and spray water and then is changed into a low-temperature low-pressure gaseous refrigerant, and the low-temperature low-pressure gaseous refrigerant returns. The circulating pump 341 drives the heated heat-exchange liquid to circulate between the reduction water tank 33 and the cooling water tank 21, when the heat-exchange liquid is heated to a higher temperature and circulates to the solid adsorption component 32, the moisture in the solid adsorption component 32 is heated by the heat-exchange liquid and evaporated into vapor to be separated out, the separated vapor is discharged to the outside along with the indoor air, and the solid adsorption component 32 realizes regeneration.
