[0037] Example 1

[0038] First refer to Figure 1 , the air conditioning system of the present invention is described. Among them, Figure 1 This is a system diagram of a first embodiment of the energy-saving air-conditioning system of the present invention.

[0039] like Figure 1 As shown, in order to solve the problem of high energy consumption of existing air conditioners, the energy-saving air conditioning system of the present application (hereinafter referred to as the air conditioning system or system) mainly includes a compressor 11, an outdoor heat exchanger 12, an outdoor fan 121, a first throttling element 13, an indoor heat exchanger 14, an indoor fan 141 and a master controller (not shown in the figure). The compressor 11, the outdoor heat exchanger 12, the outdoor fan 121, the first throttling element 13 and the master controller are arranged in the chassis 16 of the outdoor unit, and the indoor heat exchanger 14 and the indoor fan 141 are arranged in the indoor unit. Among them, the compressor 11, the outdoor heat exchanger 12, the first throttling element 13 and the indoor heat exchanger 14 are connected by a refrigerant pipe to form a refrigerant circulation, and the exhaust port of the compressor 11 is provided with a first electric control valve 111. The master controller is respectively connected to the compressor 11, the outdoor fan 121, the first electric control valve 111, the first throttling element 13 and the indoor fan 141 to control the operation of the above components. In this embodiment, the first throttling element 13 may be a valve body with controllable opening, such as an electronic expansion valve, and the first electrically controlled valve 111 may be a valve body that can be opened and closed, such as a solenoid valve.

[0040] It should be noted that in order to clearly describe the connection relationship between the above components, the components of the outdoor unit are broken up and drawn in the attached figure. Figure 1 Those skilled in the art will appreciate that the locations of these components in the drawings are not their actual locations.

[0041] Continue to refer to Figure 1 In particular, the energy-saving air-conditioning system of the present application also includes a cooling water tank 21 and a spray pipe 23. The cooling water tank 21 contains coolant. The first end of the spray pipe 23 is connected to the cooling water tank 21, and the second end is provided with a spray hole and extends to the outdoor heat exchanger 12. A water pump 231 is provided on the spray pipe 23.

[0042] Continue to refer to Figure 1The energy-saving air conditioning system further includes a dehumidification box 31, a solid adsorption component 32 and a reduction component (not shown in the figure). The dehumidification box 31 is provided with a dehumidification air inlet 311, a dehumidification air outlet 312, a reduction air inlet 313 and a reduction air outlet 314. The dehumidification air inlet 311 and the dehumidification air outlet 312 are respectively connected to the indoor room, the dehumidification air outlet 312 is provided with a dehumidification fan 315, the reduction air inlet 313 is connected to the indoor room, the reduction air outlet 314 is connected to the outdoor room, and the reduction air outlet 314 is provided with a reduction fan 316. The solid adsorption component 32 is fixed in the dehumidification box 31, and the solid adsorption component 32 includes a solid adsorbent. The reduction component includes a reduction coil 34, and the reduction coil 34 is partially coiled on the solid adsorption component 32. The first end of the reduction coil 34 is connected to the exhaust port of the compressor 11, and the second end is connected to the inlet of the outdoor heat exchanger 12, so that the reduction coil 34 allows the refrigerant (i.e., the heat exchange medium) to flow through it. In addition, a second electrically controlled valve 352 is disposed near the first end of the reduction coil 34. The second electrically controlled valve 352 in this embodiment may be a valve body such as a solenoid valve that can realize an opening and closing function.

[0043] The master controller is also connected to the water pump 231, the dehumidification fan 315, the reduction fan 316 and the second electric control valve 352 respectively to control the operation of the above components.

[0044] When the indoor temperature needs to be lowered, the master controller controls the compressor 11, the outdoor fan 121, the water pump 231 and the indoor fan 141 to start, controls the first electric control valve 111 to open, the second electric control valve 352 to close, and the first throttling element 13 to open to the set opening. At this time, the coolant in the cooling water tank 21 is driven by the water pump 231 and sprayed from the spray pipe 23 to the coil of the outdoor heat exchanger 12, and the compressor 11 discharges the high-temperature and high-pressure gaseous refrigerant. The high-temperature and high-pressure gaseous refrigerant enters the outdoor heat exchanger 12 and undergoes double heat exchange with the outdoor air and the spray water to become a medium-temperature and high-pressure liquid refrigerant. The medium-temperature and high-pressure liquid refrigerant passes through the first throttling element 13 and becomes a low-temperature and low-pressure gas-liquid two-phase refrigerant. The low-temperature and low-pressure gas-liquid two-phase refrigerant enters the indoor heat exchanger 14 and undergoes heat exchange with the indoor air to become a low-temperature and low-pressure gaseous refrigerant, and the indoor temperature drops accordingly. Then the low-temperature and low-pressure gaseous refrigerant returns to the compressor 11 from the air intake to realize the circulation of the refrigerant.

[0045] When dehumidification is required indoors, the main controller controls the dehumidification fan 315 to start running. Driven by the dehumidification fan 315, the indoor air enters the dehumidification box 31 from the dehumidification air inlet 311, and when passing through the solid adsorption component 32, the moisture in the air is adsorbed on the solid adsorbent and becomes dry air. The dry air returns to the room through the dehumidification air outlet 312, and the indoor humidity decreases accordingly.

[0046] When the solid adsorption component 32 adsorbs a certain amount of water and needs to be regenerated, the main controller controls the compressor 11, the external fan 121, the water pump 231, the internal fan 141 and the reduction fan 316 to start, controls the first electric control valve 111 to close, the second electric control valve 352 to open, and the first throttling element 13 to open to the set opening. The indoor air enters the dehumidification box 31 from the reduction air inlet 313 and is discharged to the outside from the reduction air outlet 314. The spray water sprays the outdoor heat exchanger 12 to cool it down. The high-temperature and high-pressure gaseous refrigerant discharged by the compressor 11 first circulates to the solid adsorption component 32 through the reduction coil 34 and then continues the normal refrigeration cycle. The water in the solid adsorption component 32 is heated by the high-temperature and high-pressure refrigerant and evaporates into water vapor and precipitates. The precipitated water vapor is discharged to the outside together with the indoor air, and the solid adsorption component 32 is regenerated.

[0047] It can be seen from the above description that by setting a cooling water tank 21 and a spray pipe 23 in the air conditioning system, the air conditioning system can assist the outdoor heat exchanger 12 in heat exchange by spraying coolant to the outdoor heat exchanger 12 during operation, thereby improving the heat exchange capacity of the outdoor heat exchanger 12 and reducing the operating power of the air conditioning system. By setting a dehumidification box 31, a solid adsorption component 32 and a reduction component in the air conditioning system, the air conditioning system can independently control the indoor temperature and humidity, and the dehumidification process does not need to be achieved by the cooling mode, thereby greatly reducing the energy consumption of the air conditioning system and avoiding the sudden drop in indoor temperature caused by dehumidification in the cooling mode.

[0048] Example 2

[0049] Refer to the following Figure 2 and Figure 3 , a more preferred implementation method of the present application is introduced. Among them, Figure 2 A system diagram of a second embodiment of the energy-saving air-conditioning system of the present invention; Figure 3 It is a schematic diagram of the spray direction of the spray pipe in the second embodiment of the energy-saving air-conditioning system of the present invention.

[0050] like Figure 2As shown, in a preferred embodiment, the air conditioning system mainly includes a compressor 11, an outdoor heat exchanger 12, an outdoor fan 121, an outdoor water pan 123, a return pipe 124, a first throttling element 13, an indoor heat exchanger 14, an indoor fan 141, an indoor water pan 142, a condensed water pipe 143 and a master controller (not shown in the figure). The compressor 11, the outdoor heat exchanger 12, the outdoor fan 121, the first throttling element 13 and the master controller are arranged in the chassis 16 of the outdoor unit, and a drain hole 161 is provided at the bottom of the chassis 16 near the outdoor heat exchanger 12. The outdoor water pan 123 is arranged below the drain hole 161, and one end of the return pipe 124 is connected to the outdoor water pan 123. The indoor heat exchanger 14, the indoor fan 141 and the indoor water pan 142 are arranged in the indoor unit, and one end of the condensed water pipe 143 is connected to the indoor water pan 142, and the other end is led to the outdoors. Among them, the compressor 11, the outdoor heat exchanger 12, the first throttling element 13 and the indoor heat exchanger 14 are connected by a refrigerant pipe to form a refrigerant cycle, and a first electric control valve 111 is also provided at the exhaust port of the compressor 11. The master controller is respectively connected to the compressor 11, the outdoor fan 121, the first electric control valve 111, the first throttling element 13 and the indoor fan 141 to control the operation of the above components. In this embodiment, the first throttling element 13 can be a valve body with controllable opening, such as an electronic expansion valve, and the first electric control valve 111 can be a valve body that can be opened and closed, such as a solenoid valve.

[0051] Continue to refer to Figure 2 The air conditioning system also includes a cooling water tank 21 and a spray pipe 23. The cooling water tank 21 contains a coolant, such as water or salt water, and the other end of the return pipe 124 is connected to the cooling water tank 21. The first end of the spray pipe 23 is connected to the cooling water tank 21, and a water pump 231 is provided near the first end. The second end of the spray pipe 23 extends to the outside of the outdoor heat exchanger 12, and the second end is provided with a spray hole. Specifically, the cross-section of the outdoor heat exchanger 12 is L-shaped as a whole, and the second end of the spray pipe 23 extends along the air inlet side of the outdoor heat exchanger 12 and is also roughly L-shaped. A plurality of spray holes may be provided at the second end of the spray pipe 23, and the plurality of spray holes may all be arranged at the second end of the spray pipe 23, or may be respectively arranged on a plurality of parallel sub-pipelines at the second end. Refer to Figure 3 In this embodiment, the second end of the spray pipe 23 is arranged close to the outdoor heat exchanger 12, and the spray hole faces the outdoor heat exchanger 12 and forms a certain angle with the horizontal plane. The angle can be selected between 30° and 60°, and more preferably, 45° can be selected.

[0052] By setting a cooling water tank 21 and a spray pipe 23 in the air conditioning system, the air conditioning system can assist the outdoor heat exchanger 12 in heat exchange by spraying coolant to the outdoor heat exchanger 12 during operation, thereby improving the heat exchange capacity of the outdoor heat exchanger 12 and reducing the operating power of the air conditioning system. By setting an outdoor water receiving pan 123 and a return pipe 124, a water cycle is formed between the spray pipe 23, the outdoor water receiving pan 123, the return pipe 124 and the cooling water tank 21, so that the spray water can be recycled and water resources can be saved. By placing the second end of the spray pipe 23 close to the outdoor heat exchanger 12 and the spray hole being arranged at an angle of 45°, the spray area and spray effect can be guaranteed to the greatest extent.

[0053] Return to reference Figure 2 The air conditioning system further includes a dehumidification box 31, a solid adsorption component 32 and a reduction component (not shown in the figure). The solid adsorption component 32 includes a solid adsorbent, and the reduction component includes a reduction water tank 33, a reduction coil 34, a heat exchange coil 35, a cooling heat exchanger 342 and a cooling fan 343. Among them, the dehumidification box 31 and the solid adsorption component 32 are arranged indoors, such as being arranged in the indoor unit or being arranged separately indoors, and the reduction water tank 33, the cooling water tank 21 and the cooling heat exchanger 342 are arranged outdoors, such as being arranged in the outdoor unit case 16 or being arranged separately outdoors.

[0054] The dehumidification box 31 is provided with a dehumidification air inlet 311, a dehumidification air outlet 312, a reduction air inlet 313 and a reduction air outlet 314. The dehumidification air inlet 311 and the dehumidification air outlet 312 are respectively connected to the indoor room, the dehumidification air outlet 312 is provided with a dehumidification fan 315, the reduction air inlet 313 is connected to the indoor room, the reduction air outlet 314 is connected to the outdoor room, and the reduction air outlet 314 is provided with a reduction fan 316.

[0055] The solid adsorption component 32 is fixedly arranged in the dehumidification box 31. The solid adsorption component 32 includes a solid adsorbent. In this embodiment, the solid adsorbent can be silica gel, molecular sieve, activated alumina or zeolite. The solid adsorption component 32 is formed by bonding, splicing or pressing one or more of the above solid adsorbents. The reduction coil 34 is partially coiled on the solid adsorption component 32. Specifically, the reduction coil 34 is partially coiled inside the solid adsorption component 32. Figure 2 As shown in the figure, the reduction coil 34 is wound in a partial S-shaped coil inside the solid adsorption component 32. For example, the solid adsorption component 32 and part of the reduction coil 34 are pressed together, or a hole is left inside the solid adsorption component 32 during the molding process to allow the reduction coil 34 to pass through, so that the reduction coil 34 can be installed after the solid adsorption component 32 is molded.

[0056] By partially coiling the reduction coil 34 inside the solid adsorption component 32, and further coiling it in an S shape inside the solid adsorption component 32, the coil is in direct contact with the solid adsorption component 32, which can improve the regeneration efficiency of the solid adsorption component 32 and ensure the regeneration effect.

[0057] Still refer to Figure 2 The reduction water tank 33 contains a heat exchange liquid (i.e., a heat exchange medium), such as water or salt water. The reduction coil 34 is arranged behind the solid adsorption assembly 32, and its first end is connected to the reduction water tank 33, and its second end is connected to the cooling water tank 21. The cooling water tank 21 is connected to the reduction water tank 33 through a pipeline 211, and the cooling water tank 21 is higher than the reduction water tank 33 in terms of the setting height. A circulation pump 341 is arranged near the first end of the reduction coil 34, and a cooling heat exchanger 342 is arranged near the second end. The cooling heat exchanger 342 is equipped with a cooling fan 343, and the cooling heat exchanger 342 preferably adopts a plate heat exchanger. The heat exchange coil 35 is partially arranged in the reduction water tank 33, and the part arranged in the reduction water tank 33 is S-shaped. After the heat exchange coil 35 is installed, its first end extends out of the reduction water tank 33 and communicates with the exhaust port of the compressor 11 of the air conditioning system, and its second end extends out of the reduction water tank 33 and communicates with the inlet of the outdoor heat exchanger 12 of the air conditioning system. A second electric control valve 352 is also provided near the first end of the heat exchange coil 35, such as a valve body that can realize the opening and closing function, and a second throttling element 351 is also provided near the second end of the heat exchange coil 35, such as an electronic expansion valve, etc., which can control the valve body of the opening. The first electric control valve 111 is located on the refrigerant pipe between the first end and the second end of the heat exchange coil 35.

[0058] By setting the reduction water tank 33 and the heat exchange coil 35 in the reduction component, when the solid adsorption component 32 needs to be regenerated, the high-temperature refrigerant discharged by the compressor 11 during the operation of the air-conditioning system can be used to heat the heat exchange liquid in the reduction water tank 33 through the heat exchange coil 35, and then the circulation pump 341 is used to drive the heat exchange liquid to circulate to achieve heating and regeneration of the solid adsorption component 32. By connecting the second end of the reduction coil 34 with the cooling water tank 21, the cooling water tank 21 can be used to supply water to the reduction water tank 33, and under the premise of ensuring that the heat exchange liquid is at an appropriate heating temperature, the situation of excessive evaporation and water shortage caused by the excessively high temperature of the heat exchange liquid can be prevented. Furthermore, the setting of the cooling water tank 21 can further improve the heat exchange effect of the refrigerant when the air conditioner is running, improve the operating efficiency of the air conditioner, and reduce the operating energy consumption. By arranging a cooling heat exchanger 342 and a cooling fan 343 on the reduction coil 34, the temperature of the heat exchange liquid flowing back to the cooling water tank 21 is reduced, ensuring that the water temperature in the cooling water tank 21 is kept in a relatively low range, thereby avoiding the spraying effect being affected by excessive water temperature. By arranging a first electric control valve 111 at the exhaust port of the compressor 11, and arranging a second throttling element 351 and a second electric control valve 352 at different positions of the heat exchange coil 35, the regeneration process of the solid adsorption component 32 can be independently operated without the need for the refrigeration mode, thereby avoiding the reduction in user experience caused by the reduction in indoor temperature during the regeneration process of the solid adsorption component 32.

[0059] Continue to refer to Figure 2 The side wall of the cooling water tank 21 is also provided with a water supply port (not shown in the figure), which is connected to the municipal water through a liquid level valve 212. The height of the water supply port can be set as follows: as close to the bottom of the cooling water tank 21 as possible while ensuring sufficient water circulation. The liquid level valve 212 in this embodiment refers to a valve body that can be automatically opened and closed according to the liquid level in the cooling water tank 21. For example, the liquid level valve 212 can be a liquid level ball valve or can be realized by a combination of a liquid level sensor and a solenoid valve. In addition, the condensed water pipe 143 is connected to the cooling water tank 21 after being led out of the room.

[0060] By directing the condensed water into the cooling water tank 21, the air conditioning system of the present application can further utilize the condensed water generated during the air conditioning cycle, reduce water waste, and reduce the amount of water replenishment. In addition, due to the low temperature of the condensed water, it can further reduce the temperature of the liquid in the reduction water tank 33 or the cooling water tank 21, further improving the heat exchange effect of the refrigerant. The water replenishment port is set as close as possible to the bottom of the cooling water tank 21, so that the present application can maximize the conservation of municipal water resources while ensuring the water volume, and give priority to the use of condensed water.

[0061] The main controller of the air conditioning system is also respectively connected to the water pump 231, the dehumidification fan 315, the reduction fan 316, the circulation pump 341, the second throttling element 351, the second electric control valve 352 and the cooling fan 343 to control the operation of the above components.

[0062] The main controller is connected to the water pump 231, the dehumidification fan 315, the reduction fan 316, the circulation pump 341, the second throttling element 351, the second electric control valve 352 and the cooling fan 343 respectively, so that the air-conditioning system can automatically operate the cooling spray and dehumidification, and can realize the combined control of temperature and humidity, thereby improving the degree of automation of the air-conditioning system.

[0063] Refer to the following Figure 2 , the operation process of the air-conditioning system in this embodiment is briefly described.

[0064] like Figure 2 As shown, when the indoor temperature needs to be lowered, the main controller controls the compressor 11, the outdoor fan 121, the water pump 231, the indoor fan 141, the cooling fan 343 and the circulation pump 341 to start, controls the first electric control valve 111 to close, the second electric 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 coolant in the cooling water tank 21 is sprayed from the spray pipe 23 to the coil of the outdoor heat exchanger 12 under the drive of the water pump 231, and the circulation 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 the high-temperature and high-pressure gaseous refrigerant, and the high-temperature and high-pressure gaseous refrigerant enters the reduction water tank 33 through the heat exchange coil 35 and enters the outdoor heat exchanger 12 after heat exchange with the heat exchange liquid in the reduction water tank 33. The refrigerant entering the outdoor heat exchanger 12 undergoes double heat exchange with the outdoor air and the spray water and becomes a medium-temperature and high-pressure liquid refrigerant. The medium-temperature and high-pressure liquid refrigerant is throttled by the first throttling element 13 and becomes a low-temperature and low-pressure gas-liquid two-phase refrigerant. The low-temperature and low-pressure gas-liquid two-phase refrigerant enters the indoor heat exchanger 14 and undergoes heat exchange with the indoor air and becomes a low-temperature and low-pressure gaseous refrigerant, and the indoor temperature drops accordingly. Then the low-temperature and low-pressure gaseous refrigerant returns to the compressor 11 from the air intake to realize the circulation of the refrigerant.

[0065] When dehumidification is required indoors, the main controller controls the dehumidification fan 315 to start running. Driven by the dehumidification fan 315, the indoor air enters the dehumidification box 31 from the dehumidification air inlet 311, and when passing through the solid adsorption component 32, the moisture in the air is adsorbed on the solid adsorbent and becomes dry air. The dry air returns to the room through the dehumidification air outlet 312, and the indoor humidity decreases accordingly.

[0066] When the solid adsorption component 32 adsorbs a certain amount of moisture and needs to be regenerated, if the cooling mode of the air-conditioning system is running, that is, the compressor 11, the outdoor fan 121, the water pump 231, the indoor fan 141, the cooling fan 343 and the circulating pump 341 are running, and the first electric control valve 111 is closed, the second electric control valve 352 is opened, the second throttling element 351 is fully open, and the first throttling element 13 is opened to the set opening, then at this time the main controller continues to control the reduction fan 316 to start, and the refrigerant follows the refrigeration cycle, and the indoor air enters the dehumidification box 31 from the reduction air inlet 313, and is discharged to the outdoors from the reduction air outlet 314. The 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 the heat exchange liquid in the reduction water tank 33. The circulation pump 341 drives the heat exchange liquid to circulate in the reduction water tank 33 and the cooling water tank 21. When the heat exchange liquid is heated to a higher temperature and circulated to the solid adsorption component 32, the moisture in the solid adsorption component 32 is heated by the heat exchange liquid and evaporated into water vapor and precipitated. The precipitated water vapor is discharged to the outside together with the indoor air, and the solid adsorption component 32 is regenerated.

[0067] If the air-conditioning system is not operating in cooling mode, the main controller controls the compressor 11, the outdoor 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 electric control valve 111 to close, the second electric control valve 352 to open, the second throttling element 351 to open to a certain degree, and the first throttling element 13 to be fully opened, and the indoor air enters the dehumidification box 31 from the reduction air inlet 313 and is discharged to the outside from the reduction air outlet 314. The 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 changes into a medium-temperature and high-pressure liquid refrigerant after heat exchange with the heat exchange liquid in the reduction water tank 33. The medium-temperature and high-pressure liquid refrigerant changes into a low-temperature and low-pressure gas-liquid two-phase refrigerant after throttling by the second throttling element 351. The low-temperature and low-pressure gas-liquid two-phase refrigerant enters the outdoor heat exchanger 12 and changes into a low-temperature and low-pressure gaseous refrigerant after heat exchange with the outdoor air and the spray water. Then, the low-temperature and low-pressure gaseous refrigerant passes through the indoor heat exchanger 14 and returns to the compressor 11 from the air intake to realize the circulation of the refrigerant. The circulation 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 circulated to the solid adsorption component 32, the water in the solid adsorption component 32 is heated by the heat exchange liquid and evaporated into water vapor and precipitated. The precipitated water vapor is discharged to the outside together with the indoor air, and the solid adsorption component 32 is regenerated.

[0068] It should be noted that the above preferred embodiments are only used to illustrate the principles of the present invention and are not intended to limit the scope of protection of the present invention. Without departing from the principles of the present invention, those skilled in the art may adjust the above settings so that the present invention can be applied to more specific application scenarios.

[0069] For example, in an alternative embodiment, the dehumidification fan 315 and the reduction fan 316 are not arranged at unique locations, and their locations can be changed as long as the indoor air can pass through the solid adsorption assembly 32. For example, the dehumidification fan 315 can be arranged at the dehumidification air inlet 311, and the reduction fan 316 can be arranged at the reduction air inlet 313, etc.

[0070] For another example, in another alternative embodiment, although the reduction coil 34 is described as being partially coiled inside the solid adsorption component 32 and coiled in an S shape, those skilled in the art may adjust the arrangement as long as the adjusted arrangement can enable the reduction coil 34 to heat the solid adsorption component 32. For example, the reduction coil 34 may also be wound along the outer surface of the solid adsorption component 32, or may be spirally coiled inside the solid adsorption component 32.

[0071] For example, in another replaceable embodiment, in order to achieve better technical effects for the technical solution of the present application, the technicians in this field can also add additional parts on the basis of the present embodiment. Such adjustments commonly used in this field do not deviate from the principles of the present application. For example, in order to improve the flow effect of the flowing air entering the dehumidification box 31 during the dehumidification process and the regeneration process, the technicians in this field can respectively set inlet / outlet valves on the dehumidification air inlet 311, the dehumidification air outlet 312, the reduction air inlet 313 and the reduction air outlet 314, so as to control the air flow direction by controlling the opening and closing of the inlet / outlet valves during the dehumidification process and the regeneration process; for example, in order to improve the contact effect between the flowing air and the solid adsorption component 32, the technicians in this field can also set a plurality of baffles in the dehumidification box 31, so that the airflow entering the dehumidification box 31 repeatedly passes through the solid adsorption component 32 according to the path defined by the baffles, thereby improving the utilization rate and adsorption effect of the solid adsorption component 32.

[0072] For example, in another replaceable embodiment, although the water supply port is arranged on the side wall of the cooling water tank 21 in the above embodiment, the setting position of the water supply port is not unique. Technical personnel in this field can also set the water supply port at other positions, such as on the reduction water tank 33.

[0073] For another example, in another alternative embodiment, those skilled in the art may selectively omit one or more of the following components in a specific application so that the present application can meet different application scenarios. The components include but are not limited to: cooling heat exchanger 342, cooling fan 343, first electric control valve 111, second electric control valve 352, second throttling element 351, indoor water tray 142, condensate pipe 143.

[0074] Of course, the above-mentioned replaceable implementations, as well as the replaceable implementations and the preferred implementations, can be used in a cross-coordinated manner to combine new implementations to suit more specific application scenarios.

[0075] Example 3

[0076] Combine the following Figure 4 , another alternative implementation of the present invention is introduced. Among them, Figure 4 This is a system diagram of a third embodiment of the energy-saving air-conditioning system of the present invention.

[0077] like Figure 4 As shown, the difference between this embodiment and embodiment 2 is that the condensed water pipe 143 is connected to the reduction water tank 33 after being led out of the room, and the water supply port of the cooling water tank 21 is arranged on the side wall away from the bottom of the cooling water tank 21. The arrangement of the condensed water pipe 143 and the reduction water tank 33 in communication can improve the heat exchange effect between the refrigerant in the reduction water tank 33 and the heat exchange liquid, improve the operating efficiency of the air conditioning system, and reduce the energy consumption of the system. The water supply port of the cooling water tank 21 is arranged on the side wall away from the bottom of the cooling water tank 21 to ensure the amount of water in the cooling water tank 21 when the air conditioning system is running, thereby improving the heat exchange effect between the refrigerant in the reduction water tank 33 and the heat exchange liquid, improving the efficiency of the air conditioning system, and further reducing energy consumption.

[0078] Example 4

[0079] Combine the following Figure 5 , another alternative implementation of the present invention is introduced. Among them, Figure 5 It is a schematic diagram of the spray direction of the spray pipe in the fourth embodiment of the energy-saving air-conditioning system of the present invention.

[0080] like Figure 5 As shown, the difference between this embodiment and embodiment 2 is that the spray hole is arranged along the air inlet direction of the outdoor unit, facing away from the outdoor heat exchanger 12. This arrangement can make the spray water diverge in a cone shape and the spray coverage area gradually expand. At the same time, the spray water is re-sucked into the chassis 16 through the negative pressure generated by the rotation of the outdoor fan 121, so that the spray water can cover a larger surface area of ​​the outdoor heat exchanger 12, increasing the spray coverage area of ​​the outdoor heat exchanger 12, and also making the second end of the spray pipe 23 close to the outdoor heat exchanger 12, saving space in the outdoor unit.

[0081] Those skilled in the art can understand that the above-mentioned master controller also includes some other well-known structures, such as processors, controllers, memories, etc., wherein the memories include but are not limited to random access memory, flash memory, read-only memory, programmable read-only memory, volatile memory, non-volatile memory, serial memory, parallel memory or registers, etc., and the processors include but are not limited to CPLD / FPGA, DSP, ARM processor, MIPS processor, etc. In order to unnecessarily obscure the embodiments of the present disclosure, these well-known structures are not shown in the drawings.

[0082] In addition, those skilled in the art will appreciate that, although some embodiments described herein include certain features included in other embodiments but not other features, the combination of features of different embodiments is meant to be within the scope of the present invention and form different embodiments. For example, in the claims of the present invention, any one of the claimed embodiments may be used in any combination.

[0083] So far, the technical solutions of the present invention have been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it is easy for those skilled in the art to understand that the protection scope of the present invention is obviously not limited to these specific embodiments. Without departing from the principle of the present invention, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will fall within the protection scope of the present invention.
