In addition, the water replenishing port is arranged to be close to the bottom of the cooling water tank 56 as far as possible, so that the dehumidification device 5 can save municipal water resources to the maximum extent on the premise of ensuring the circulating water quantity, and preferentially ensures that collected rainwater and indoor discharged condensed water are used.

Of course, since the electric energy converted by the photovoltaic module 57 does not necessarily satisfy the requirements of all the electric components, although not shown in the drawings, the corresponding commercial power still needs to be configured, but the electric energy converted and stored by the photovoltaic module 57 is preferentially used in the embodiment.

Still referring to fig. 2, the general controller 6 of the air conditioning system is further connected to the dehumidifying fan 515, the reducing fan 516, the circulating pump 541, the first throttling element 551, the second electrically controlled valve 552 and the cooling fan 581, respectively, for controlling the above components to operate.

The main controller 6 is respectively connected with the dehumidifying fan 515, the restoring fan 516, the circulating pump 541, the first throttling element 551, the second electric control valve 552 and the cooling fan 581, so that the dehumidifying device 5 can automatically operate, the temperature and humidity combined control of the air conditioning system can be realized, and the automation degree of the air conditioning system is improved.

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 6 controls the compressor 1, the outer fan 21, the inner fan 41, the temperature reduction fan 581 and the circulating pump 541 to start, controls the first electronic control valve 11 to close, the second electronic control valve 552 to open, the first throttling element 551 to fully open, and the second throttling element 3 to open to a set opening, and preferentially uses the electric energy converted by the photovoltaic panel 571 and the electric energy stored in the storage battery to supply power to the above components. The circulating pump 541 drives the heat-exchange liquid to circulate between the reduction water tank 53 and the cooling water tank 56, the compressor 1 discharges high-temperature high-pressure gaseous refrigerant, the high-temperature high-pressure gaseous refrigerant enters the reduction water tank 53 through the heat-exchange coil 55 and exchanges heat with the heat-exchange liquid in the reduction water tank 53 and then enters the outdoor heat exchanger 2, the refrigerant entering the outdoor heat exchanger 2 further exchanges heat with outdoor air and then becomes 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 second throttling element 3, the low-temperature low-pressure gas-liquid two-phase refrigerant enters the indoor heat exchanger 4 and exchanges heat with indoor air and then becomes low-temperature low-pressure gaseous refrigerant, the indoor. Then the low-temperature low-pressure gaseous refrigerant returns to the compressor 1 through the air suction port to realize the circulation of the refrigerant.

When dehumidification is needed indoors, the master controller 6 controls the dehumidification fan 515 to start and operate, and preferentially uses the electric energy converted by the photovoltaic panel 571 and the electric energy stored in the storage battery to supply power to the dehumidification fan 515. The indoor air enters the dehumidifying box 51 from the dehumidifying air inlet 511 under the driving of the dehumidifying fan 515, and the moisture in the air is adsorbed on the solid adsorbent to become dry air when passing through the solid adsorbing assembly 52, the dry air returns to the room through the dehumidifying air outlet 512, and the indoor humidity is reduced along with the reduction of the indoor humidity, so that the indoor dehumidification is realized.

When the solid adsorption component 52 adsorbs a certain amount of moisture and needs regeneration, if the refrigeration mode of the air conditioning system is running, that is, the compressor 1, the outer fan 21, the inner fan 41, the cooling fan 581 and the circulation pump 541 are running, the first electronic control valve 11 is closed, the second electronic control valve 552 is opened, the first throttling element 551 is fully opened, and the second throttling element 3 is opened to a set opening degree, then the master controller 6 continues to control the reduction fan 516 to start at this time, and preferentially uses the electric energy converted by the photovoltaic panel 571 and the electric energy stored in the storage battery to supply power to each component. At this time, the refrigerant enters the dehumidification tank 51 through the return air inlet 513 according to the refrigeration cycle, and is discharged to the outside through the return air outlet 514. The high-temperature high-pressure gaseous refrigerant discharged from the compressor 1 enters the reduction water tank 53 through the heat exchange coil 55 and heats the heat-exchange liquid in the reduction water tank 53, and the circulating pump 541 drives the heat-exchange liquid to circulate between the reduction water tank 53 and the cooling water tank 56. When the heat-exchange liquid is heated to a higher temperature and circulated to the solid adsorption element 52, moisture in the solid adsorption element 52 is heated by the heat-exchange liquid and evaporated into water vapor to be separated out, the separated water vapor is discharged to the outdoor along with indoor air, and the solid adsorption element 52 is regenerated.

If the air conditioning system does not operate in the cooling mode, at this time, the main controller 6 controls the compressor 1, the external fan 21, the cooling fan 581, the reduction fan 516 and the circulating pump 541 to start, controls the first electronic control valve 11 to close, the second electronic control valve 552 to open, the first throttling element 551 to open to a certain opening degree, and the second throttling element 3 to be fully open, and preferentially uses the electric energy converted by the photovoltaic panel 571 and the electric energy stored in the storage battery to supply power to each component. At this time, the indoor air enters the dehumidifying tank 51 through the return air inlet 513 and is discharged to the outside through the return air outlet 514. The high-temperature high-pressure gaseous refrigerant discharged from the compressor 1 enters the reduction water tank 53 through the heat exchange coil 55, is subjected to heat exchange with the heat exchange liquid in the reduction water tank 53 and then is changed into a medium-temperature high-pressure liquid refrigerant, the medium-temperature high-pressure liquid refrigerant is throttled by the first throttling element 551 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 2 to undergo heat exchange with outdoor air and then is changed into a low-temperature low-pressure gaseous refrigerant, and the low-temperature low-pressure gaseous refrigerant returns to the. The circulating pump 541 drives the heated heat-exchange liquid to circulate between the reduction water tank 53 and the cooling water tank 56, when the heat-exchange liquid is heated to a higher temperature and circulates to the solid adsorption component 52, moisture in the solid adsorption component 52 is heated by the heat-exchange liquid to be evaporated into water vapor and separated out, the separated water vapor is discharged to the outside along with indoor air, and the solid adsorption component 52 realizes regeneration.

For example, in an alternative embodiment, the positions of the dehumidification fan 515 and the reduction fan 516 are not exclusive, and may be changed if the conditions for allowing the indoor air to pass through the solid adsorption module 52 are satisfied. For example, the dehumidifying fan 515 may be further provided at the dehumidifying air inlet 511, the reducing fan 516 may be further provided at the reducing air inlet 513, and the like.

For another example, in another alternative embodiment, although the above-mentioned reduction coil 54 is described with a combined portion of the coil disposed inside the solid adsorbent assembly 52 and wound in an S-shape, the skilled person can adjust the arrangement thereof as long as the adjusted arrangement enables the reduction coil 54 to heat the solid adsorbent assembly 52. For example, the reducing coil 54 may be wound along the outer surface of the solid adsorbent assembly 52, or may be helically wound around the inner surface of the solid adsorbent assembly 52, or the like.

For example, in another alternative embodiment, in order to achieve better technical effects of the technical solution of the present application, a person skilled in the art may also add additional components to the technical solution in a targeted manner, and such modifications commonly used in the art do not depart from the principle of the present application. For example, in order to improve the flowing effect of the flowing air entering the dehumidification box 51 during the dehumidification process and the regeneration process, a person skilled in the art may set air inlet/outlet valves on the dehumidification air inlet 511, the dehumidification air outlet 512, the reduction air inlet 513, and the reduction air outlet 514, respectively, so as to control the air flowing direction by controlling the opening and closing of the air inlet/outlet valves during the dehumidification process and the regeneration process; for another example, in order to improve the contact effect between the flowing air and the solid adsorption component 52, a person skilled in the art may further provide a plurality of baffles in the dehumidification box 51, so that the airflow entering the dehumidification box 51 repeatedly passes through the solid adsorption component 52 according to a path defined by the baffles, thereby improving the utilization rate and the adsorption effect of the solid adsorption component 52.
