[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means intended to limit the present invention and its application or use. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] In order to solve the problem that condensed water on the indoor evaporator of the air-conditioning system in the prior art is directly lost without being effectively utilized, the present invention provides an air-conditioning system and an air conditioner having the same, wherein the air conditioner includes an air-conditioning system, and the air-conditioning system is the air-conditioning system described above and below.

[0032] like Figure 1 As shown, the air-conditioning system includes a spray device 10, a water receiving device 20 and a return pipeline 30, wherein the spray device 10 has a spray part 11, the spray device 10 is connected to the air-conditioning indoor unit 1 of the air-conditioning system to guide the condensed water of the air-conditioning indoor unit 1 to the spray part 11, and the spray device 10 is arranged on one side of the air-conditioning outdoor unit 2 of the air-conditioning system; the water receiving device 20 is arranged on the side of the air-conditioning outdoor unit 2 opposite to the spray device 10, and the water receiving device 20 is used to collect the condensed water falling from the air-conditioning outdoor unit 2; the first end of the return pipeline 30 is connected to the spray part 11, and the second end of the return pipeline 30 is connected to the water receiving device 20, and the return pipeline 30 is used to recover the circulating liquid in the water receiving device 20.

[0033] By arranging a return pipe 30 between the water receiving device 20 and the spraying device 10 of the air-conditioning system, when the condensed water on the surface of the air-conditioning indoor unit 1 is sprayed to the air-conditioning outdoor unit 2 through the spraying part 11 on the spraying device 10, part of the condensed water absorbs a large amount of heat on the surface of the air-conditioning outdoor unit 2 and evaporates, thereby achieving the purpose of cooling the air-conditioning outdoor unit 2, and the other part of the condensed water that has not evaporated in time flows into the water receiving device 20, and is reintroduced into the spraying part 11 of the spraying device 10 through the return pipe 30, so as to repeatedly cool the air-conditioning outdoor unit 2, thereby ensuring that the condensed water can be effectively utilized repeatedly, avoiding the loss of the condensed water, and also facilitating the energy saving of the air-conditioning system.

[0034] like Figure 5 and Figure 6 As shown, the spray part 11 includes a first spray hole 111 and a second spray hole 112 which are independently arranged. The condensed water of the air conditioner indoor unit 1 is sprayed toward the air conditioner outdoor unit 2 through the first spray hole 111, and the circulating liquid in the water receiving device 20 is sprayed toward the air conditioner outdoor unit 2 through the second spray hole 112. In this way, the condensed water of the air conditioner indoor unit 1 in the spray part 11 on the spray device 10 is prevented from heat exchange with the circulating liquid in the water receiving device 20, thereby ensuring that the temperature of the condensed water of the air conditioner indoor unit 1 is maintained as much as possible.

[0035] like Figure 1 , Figure 4 and Figure 5As shown, the spray device 10 includes a housing 12 and a partition 13, the housing 12 has a flow cavity; the partition 13 is arranged in the flow cavity to divide the flow cavity into a first flow channel 14 and a second flow channel 15; a first spray hole 111 is provided at the position of the housing 12 having the first flow channel 14, the first spray hole 111 is connected to the first flow channel 14, the condensed water of the air conditioner indoor unit 1 flows into the first flow channel 14, and is sprayed to the air conditioner outdoor unit 2 from the first spray hole 111; a second spray hole 112 is provided at the position of the housing 12 having the second flow channel 15, the second spray hole 112 is connected to the second flow channel 15, the circulating liquid in the water receiving device 20 flows into the second flow channel 15, and is sprayed to the air conditioner outdoor unit 2 from the second spray hole 112. In this way, the condensed water of the air conditioner indoor unit 1 and the circulating liquid in the water receiving device 20 can flow independently, avoiding the contact between the two to generate heat exchange and cause the water temperature of the condensed water of the air conditioner indoor unit 1 to rise.

[0036] Optionally, the first spray hole 111 and the second spray hole 112 are both arranged toward the air-conditioning outdoor unit 2. In this way, the spray reliability of the spray device 10 is ensured, thereby ensuring that the spray device 10 can effectively cool the air-conditioning outdoor unit 2.

[0037] It should be noted that, in the present application, the air-conditioning outdoor unit 2 includes a condenser 100, a fin structure is provided on the heat exchange tube of the condenser 100, and the distance between two adjacent fin structures is L; there are multiple first spray holes 111, and the multiple first spray holes 111 are arranged at intervals along the length direction of the shell 12, and the distance between the hole centers of two adjacent first spray holes 111 is L1, wherein L≤L1≤1.4L; and / or, there are multiple second spray holes 112, and the multiple second spray holes 112 are arranged at intervals along the length direction of the shell 12, and the distance between the hole centers of two adjacent second spray holes 112 is L2, wherein L≤L2≤1.4L. In this way, it is ensured that the multiple first spray holes 111 can spray the condensed water of the air-conditioning indoor unit 1 onto the fin structure as much as possible, and it is ensured that the multiple second spray holes 112 can spray the circulating liquid in the water receiving device 20 onto the fin structure as much as possible, so as to effectively cool the air-conditioning outdoor unit 2.

[0038] It should be noted that, in the present application, the centers of the multiple first spray holes 111 are located on the first straight line, the centers of the multiple second spray holes 112 are located on the second straight line, and the first straight line and the second straight line are arranged at intervals in the width direction of the housing 12. In this way, the multiple first spray holes 111 spray simultaneously onto the condenser 100 of the air-conditioning outdoor unit 2 to form a first row of water curtains, and the multiple second spray holes 112 spray simultaneously onto the condenser 100 of the air-conditioning outdoor unit 2 to form a second row of water curtains, wherein the first row of water curtains along the air flow direction is condensed water with a lower temperature, and the second row of water curtains is located at the center of the width direction of the condenser 100, which is condensed water that has been heated multiple times, and the first row of water curtains and the second row of water curtains simultaneously enhance the heat exchange effect of the condenser 100.

[0039] It should be noted that in the present application, the spray device 10 is arranged directly above the air-conditioning outdoor unit 2 including the condenser 100, and the shape of the spray device 10 is adapted to the shape of the top surface of the condenser 100, and the water receiving device 20 is arranged directly below the air-conditioning outdoor unit 2 to ensure that the water on the air-conditioning outdoor unit 2 can smoothly flow into the water receiving cavity of the water receiving device 20.

[0040] Optionally, the diameter of the first spray hole 111 is R1, wherein 0.5 mm ≤ R1 ≤ 1.2 mm; and / or the diameter of the second spray hole 112 is R2, wherein 0.5 mm ≤ R2 ≤ 1.2 mm. In this way, it is ensured that the condensed water of the air conditioner indoor unit 1 and the circulating liquid in the water receiving device 20 can drip evenly on the fin structure, thereby ensuring that the fin structure can be evenly cooled, and further ensuring the working reliability of the condenser 100.

[0041] like Figure 5 As shown, the spray device 10 includes a first overflow structure 16, which is arranged in the second flow channel 15 to divide the second flow channel 15 into a first liquid storage chamber 151 and a first liquid discharge chamber 152, which are connected to each other. The first liquid discharge chamber 152 is connected to the second spray hole 112; the circulating liquid in the first liquid storage chamber 151 can overflow the end of the first overflow structure 16 and flow into the first liquid discharge chamber 152 evenly. In this way, it is ensured that the flow rate of the circulating liquid in the water receiving device 20 entering the first liquid discharge chamber 152 can be as close as possible to the flow rate of the condensed water of the air conditioner indoor unit 1 entering the first flow channel 14, and it is ensured that the circulating liquid in the water receiving device 20 and the condensed water of the air conditioner indoor unit 1 can be evenly sprinkled on the condenser 100.

[0042] like Figure 5As shown, the first overflow structure 16 includes a first overflow plate 161 and a guide plate 162, wherein the first overflow plate 161 is connected to the wall surface of the second flow channel 15, and the first overflow plate 161 is used to divide the second flow channel 15 into a first liquid storage chamber 151 and a first liquid discharge chamber 152; the first end of the guide plate 162 is connected to the first overflow plate 161, and is arranged at an angle with the first overflow plate 161, and the second end of the guide plate 162 is extended toward the partition 13, and is arranged at a distance from the partition 13, so as to form a first connecting port 90 for connecting the first liquid storage chamber 151 and the first liquid discharge chamber 152. In this way, the overflow reliability of the first overflow structure 16 is ensured, and the guide plate 162 plays a guiding role for the circulating liquid in the water receiving device 20, ensuring that the circulating liquid in the water receiving device 20 can flow smoothly into the first liquid discharge chamber 152 along the guide plate 162.

[0043] like Figure 5 As shown, the spray device 10 also includes a second overflow structure, which includes a second overflow plate 17. The second overflow plate 17 is arranged in the first liquid discharge chamber 152 to divide the first liquid discharge chamber 152 into a second liquid storage chamber 1521 and a second liquid discharge chamber 1522 that are connected. The second liquid storage chamber 1521 is connected to the first connecting port 90, and the second liquid discharge chamber 1522 is connected to the second spray hole 112; the circulating liquid in the second liquid storage chamber 1521 can overflow over the end of the second overflow plate 17 and flow evenly into the second liquid discharge chamber 1522. In this way, the flow rate of the circulating liquid in the water receiving device 20 entering the first liquid discharge chamber 152 is further reduced, ensuring that the flow rate of the circulating liquid in the water receiving device 20 entering the first liquid discharge chamber 152 can be as close as possible to the flow rate of the condensed water of the air-conditioning indoor unit 1 entering the first flow channel 14, ensuring that the circulating liquid in the water receiving device 20 and the condensed water of the air-conditioning indoor unit 1 can be evenly sprinkled on the condenser 100, ensuring that most of the condenser 100 can be fully in contact with water, so that the heat absorption effect of water evaporation is optimal, and reducing the flow rate entering the second flow channel 15 of the spray device 10 is beneficial to reducing the consumption of external water sources to a certain extent.

[0044] It should be noted that, in the present application, the external water source may be tap water, or domestic waste water or other water sources after a certain degree of filtration.

[0045] Optionally, the second overflow plate 17 is connected to the wall surface of the second flow channel 15 connected to the first overflow plate 161, and the height of the second overflow plate 17 is lower than the height of the first overflow plate 161. In this way, the flow reliability of the circulating liquid in the water receiving device 20 in the second flow channel 15 is ensured, and the first overflow structure 16 and the second overflow structure can effectively reduce the flow rate of the circulating liquid flowing into the second flow channel 15.

[0046] like Figures 2 to 6As shown, the spray device 10 further includes a first pipe 18 and a second pipe 19, wherein the first pipe 18 is connected to the housing 12, the first end of the first pipe 18 is communicated with the first flow channel 14, and the second end of the first pipe 18 is communicated with the air conditioner indoor unit 1 through the drainage pipe 40; the second pipe 19 is connected to the housing 12, the first end of the second pipe 19 is communicated with the second flow channel 15, and the second end of the second pipe 19 is communicated with the water receiving device 20 through the return pipe 30. In this way, it is ensured that the condensed water of the air conditioner indoor unit 1 can flow smoothly into the first flow channel 14 through the drainage pipe 40 and the first pipe 18 in sequence, and it is ensured that the circulating liquid in the water receiving device 20 can flow smoothly into the second pipe 19 through the return pipe 30 and the second pipe 19 in sequence, thereby ensuring the operation reliability of the spray device 10.

[0047] It should be noted that in the present application, when the amount of condensed water generated by the air-conditioning indoor unit 1 is small, or the condensed water completely evaporates and disappears, in order to avoid insufficient circulating fluid in the water receiving device 20 and failure to ensure normal operation of the air-conditioning system, Figure 1 As shown, the air conditioning system further includes a water supply pipe 50 and a circulation pump 60, wherein the first end of the water supply pipe 50 is connected to an external water source, and the second end of the water supply pipe 50 is connected to the water receiving device 20; the circulation pump 60 is arranged in the water receiving device 20 and is connected to the second end of the return pipe 30. In this way, it is ensured that the spray device 10 can still operate efficiently and continuously during the period of lack of condensed water, thereby solving the problem that the time for water flow to perform evaporative cooling and heat exchange on the air conditioning outdoor unit 2 is very short, and the energy efficiency improvement effect of the air conditioning system is not obvious.

[0048] like Figure 1 As shown, the air conditioning system further includes a first detection device 70 and a control module, wherein the first detection device 70 is arranged on the drainage pipeline 40, and the first detection device 70 is used to detect the flow information of the condensed water flowing into the first flow channel 14; the control module is connected to the water supply pipeline 50, and the control module controls the connection and disconnection of the water supply pipeline 50 and the water receiving device 20 according to the flow information. The air conditioning system further includes a second detection device 80, which is arranged in the water receiving device 20, and the second detection device 80 is used to detect the water level information of the circulating water in the water receiving device 20; the control module is connected to the circulating pump 60, and the control module controls the operation of the circulating pump 60 according to the water level information.

[0049] It should be noted that, in the present application, the circulation pump 60 has a water shortage protection function.

[0050] Specifically, when the first detection device 70 detects that the flow rate of condensed water flowing into the first flow channel 14 is greater than zero, the control module controls the water replenishment pipe 50 to be disconnected from the water receiving device 20 according to the flow information, that is, the water replenishment pipe 50 does not replenish water, thereby ensuring the energy saving of the air-conditioning system; when the first detection device 70 detects that the flow rate of condensed water flowing into the first flow channel 14 is less than zero, the control module controls the water replenishment pipe 50 to be connected to the water receiving device 20 according to the flow information, that is, the water replenishment pipe 50 replenishes water; during the process of replenishing water in the water replenishment pipe 50, when the second detection device 80 detects that the water level information of the circulating liquid in the water receiving device 20 reaches the first preset water level value, the control module controls the circulating pump 60 to start according to the water level information, so as to transport the circulating liquid in the water receiving device 20 to the second pipe 19 of the spray device 10; when the second detection device 80 detects that the water level information of the circulating liquid in the water receiving device 20 reaches the second preset water level value, the control module controls the circulating pump 60 to stop according to the water level information.

[0051] It should be noted that in the present application, when the temperature measuring element of the air-conditioning outdoor unit 2 detects that the ambient temperature is higher than 38°C and the relative humidity is lower than 42%, the control module controls the circulation pump 60 to start, so as to transport the circulating liquid in the water receiving chamber of the water receiving device 20 to the second flow channel 15, so that the spray device 10 starts the water spraying operation; when the temperature measuring element of the air-conditioning outdoor unit 2 detects that the ambient temperature is lower than 38°C, or the relative humidity of the environment is higher than 52%, at this time, the heat exchange condition of the condenser 100 of the air-conditioning outdoor unit 2 is good or the effect of water evaporation cooling is not obvious, and there is no need to enhance the heat exchange of the condenser 100, and the spray device 10 is operated to reduce the consumption of water resources.

[0052] It should be noted that, in the present application, the circulating liquid in the water receiving device 20 is condensed water that has not evaporated in time.

[0053] It should be noted that, in the present application, the surface of the housing 12 on one side opposite to the air-conditioning outdoor unit 2 is matched with the surface of the air-conditioning outdoor unit 2 on the side facing the housing 12 .

[0054] It should be noted that, in the present application, the second pipe 19 is disposed on a side of the housing 12 opposite to the first pipe 18 .

[0055] Optionally, there are two second pipes 19 and two first pipes 18 , and the two second pipes 19 are respectively disposed close to two ends of the shell 12 , and the two first pipes 18 are respectively disposed away from two ends of the shell 12 .

[0056] It should be noted that in the present application, when the amount of condensed water generated by the air-conditioning indoor unit 1 is large, the above-mentioned condensed water flows through the drainage pipe 40 and smoothly flows into the first flow channel 14 through the two first pipes 18, and then is evenly sprayed toward the air-conditioning outdoor unit 2 through the first spray hole 111 in the first flow channel 14. The condensed water falling on the surface of the condenser 100 of the air-conditioning outdoor unit 2 absorbs heat and evaporates, thereby enhancing the heat exchange performance of the condenser 100, which is beneficial to reducing the power consumption of the air-conditioning system. The condensed water on the surface of the condenser 100 of the air-conditioning outdoor unit 2 that has not evaporated in time flows into the water receiving chamber of the water receiving device 20, and the circulating pump 60 transports the condensed water in the water receiving chamber of the water receiving device 20 that has not evaporated in time through the reflux pipe 30 and the two second pipes 19 to the second flow channel 15.
