[0035] The embodiments of the present invention will be described in detail below. Examples of the embodiments are shown in the accompanying drawings, where the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present invention and should not be construed as limiting the present invention.

[0036] The following disclosure provides many different embodiments or examples for implementing different structures of the present invention. To simplify the disclosure of the present invention, components and settings of specific examples are described below. Of course, they are merely examples and are not intended to limit the present invention. In addition, the present invention may repeat reference numerals and / or letters in different examples. Such repetition is for the purpose of simplification and clarity and does not in itself indicate the relationship between the various embodiments and / or settings discussed. In addition, the present invention provides examples of various specific processes and materials, but those of ordinary skill in the art can recognize the applicability of other processes and / or the use of other materials.

[0037] Next, with reference to the accompanying drawings, an air conditioner 100 according to an embodiment of the present invention will be described.

[0038] As Figures 1 - 12 shown, the air conditioner 100 according to an embodiment of the present invention includes: an air handling component 1, the air handling component 1 includes a first heat exchanger 11, a water supply assembly 12, and a first fan 19. The water supply assembly 12 is used to supply water to the first heat exchanger 11, the first fan 19 is used to make air flow through the first heat exchanger 11, the first heat exchanger 11 is connected to the refrigerant circulation system 2 of the air conditioner 100, and the refrigerant circulation system 2 is configured to make the first heat exchanger 11 in a heat release state. Among them, the first heat exchanger 11 has a relatively high temperature in the heat release state and can heat the air flowing through it so that the air can carry more moisture.

[0039] Thereby, the air flow flowing through the first heat exchanger 11 can carry more moisture, improving the humidification efficiency of the air conditioner 100, and when the refrigerant circulation system 2 is in the heating mode, the heating efficiency of the air conditioner 100 can also be improved.

[0040] For example, with reference to Figures 1 - 3 shown, the air conditioner 100 includes an air handling component 1, the air handling component 1 includes a first heat exchanger 11, a water supply assembly 12, and a first fan 19. The water supply assembly 12 is used to supply water to the first heat exchanger 11 so that there is moisture on the first heat exchanger 11. The first fan 19 is used to drive air to flow through the first heat exchanger 11. The air flow flowing through the first heat exchanger 11 can take away the moisture on the first heat exchanger 11, and the air flow with moisture can flow into the indoor space to humidify the indoor space.

[0041] The air conditioner 100 further includes a refrigerant circulation system 2. The refrigerant circulation system 2 is used to cool or heat the indoor space. The first heat exchanger 11 is adapted to be connected into the refrigerant circulation system 2, and the refrigerant circulation system 2 is configured to make the first heat exchanger 11 have a heat-releasing state. That is to say, when the refrigerant circulation system 2 is in the cooling mode or the heating mode, the first heat exchanger 11 can be switched to the heat-releasing state. In the heat-releasing state, the first heat exchanger 11 heats the air flow and accelerates the evaporation of moisture, so that the air flow passing through the first heat exchanger 11 can take away more moisture, improving the humidification efficiency of the air handling component 1. Moreover, the operating noise and operating cost of the first heat exchanger 11 are relatively low, improving the practicability of the air handling component 1.

[0042] In addition, when the refrigerant circulation system 2 is in the heating mode and the first heat exchanger 11 is in the heat-releasing state, the refrigerant circulation system 2 and the first heat exchanger 11 can jointly heat the indoor space, which can avoid the cold air of the air handling component 1 blowing directly into the indoor space and is beneficial to improving the heating efficiency of the air conditioner 100.

[0043] According to the air conditioner 100 of the embodiment of the present invention, by setting the first heat exchanger 11 to have a heat-releasing state, the first heat exchanger 11 can evaporate moisture and heat the air flow in the heat-releasing state, so that the air flow passing through the first heat exchanger 11 can carry more moisture, improving the humidification efficiency of the air conditioner 100. Moreover, when the refrigerant circulation system 2 is in the heating mode, the heating efficiency of the air conditioner 100 can also be improved, enhancing the practicability of the air conditioner 100. Also, compared with ultrasonic humidification, no large amount of water mist will be generated, which can improve the air flow quality. Compared with wet film humidification, the consumption of the wet film can be saved, reducing the humidification cost.

[0044] In some embodiments of the present invention, the refrigerant circulation system 2 is configured to make the first heat exchanger 11 also have a cold-releasing state. That is to say, when the refrigerant circulation system 2 is in the cooling mode or the heating mode, the first heat exchanger 11 can be switched to the cold-releasing state. In the cold-releasing state, the temperature of the first heat exchanger 11 is relatively low. Thus, the first heat exchanger 11 can exchange heat with the air flow in the cold-releasing state to cool the air flow. When the cooled air flow flows into the indoor space, cooling can be performed. That is, in the cooling mode of the refrigerant circulation system 2, the evaporator and the first heat exchanger 11 can jointly cool the indoor space. Thereby, the cooling efficiency of the air conditioner 100 can be improved. Or, in the heating mode, the first heat exchanger 11 in the cold-releasing state can be used to improve the heat exchange efficiency of the cold end, thereby enhancing the heating effect of the condenser of the refrigerant circulation system 2.

[0045] In some embodiments of the present invention, refer to Figure 3As shown, the refrigerant circulation system 2 includes a second heat exchanger 21 and a third heat exchanger 22 connected in series to the first flow path S1, and a switching valve 23 for switching the flow direction of the first flow path S1. The first heat exchanger 11 is provided in the first flow path S1 and connected in series between the second heat exchanger 21 and the third heat exchanger 22. A first throttle valve 251 and a first solenoid valve 252, which are connected in parallel, are further provided on the first flow path S1 and connected in series between the third heat exchanger 22 and the first heat exchanger 11, and a second throttle valve 261 and a second solenoid valve 262, which are connected in parallel, are connected in series between the second heat exchanger 21 and the first heat exchanger 11.

[0046] For example, referring to Figure 3 As shown, the refrigerant circulation system 2 includes a first flow path S1 and a compressor 24. The refrigerant circulation system 2 includes a second heat exchanger 21 and a third heat exchanger 22. The third heat exchanger 22, the first heat exchanger 11, and the second heat exchanger 21 are sequentially connected in series within the first flow path S1. The second heat exchanger 21 is located in the indoor portion of the air conditioner 100 and is used for adjusting the indoor temperature. The refrigerant circulation system 2 further includes a switching valve 23. The switching valve 23 is configured as a four-way valve. Two ports of the switching valve 23 (i.e., Figure 3 the S port and the D port in Figure 3 are respectively connected to both ends of the compressor 24, and the other two ports (i.e.,

[0047] the E port and the C port in

[0048] are respectively connected to the second heat exchanger 21 and the third heat exchanger 22, so that the switching valve 23 can switch the flow direction of the first flow path S1. Specifically, the switching valve 23 can be switched to a first state, so that the refrigerant flows through the compressor 24, the third heat exchanger 22, the first heat exchanger 11, and the second heat exchanger 21 in sequence, and the first switching valve 23 can be switched to a second state, so that the refrigerant flows through the compressor 24, the second heat exchanger 21, the first heat exchanger 11, and the third heat exchanger 22 in sequence. Figure 4As shown, when the refrigerant circulation system 2 is in the refrigeration mode and the first heat exchanger 11 is in the heat release state, the first solenoid valve 252 is closed, the second solenoid valve 262 is opened, and the switching valve 23 is switched to the first state. The compressed refrigerant can flow from the compressor 24 into the third heat exchanger 22 and release heat. After releasing heat, the refrigerant can flow through the first throttle valve 251 and into the first heat exchanger 11 and the second heat exchanger 21 in sequence. The refrigerant can absorb heat in the first heat exchanger 11 and the second heat exchanger 21 to achieve refrigeration. After absorbing heat, the refrigerant can flow back into the compressor 24 for compression.

[0049] Exemplarily, as Figure 5 shown, when the refrigerant circulation system 2 is in the heating mode and the first heat exchanger 11 is in the heat release state, the first solenoid valve 252 is closed, the second solenoid valve 262 is opened, and the switching valve 23 is switched to the second state. The compressed refrigerant can flow out of the compressor 24 and into the second heat exchanger 21 and the first heat exchanger 11 in sequence. The refrigerant can release heat in the first heat exchanger 11 and the second heat exchanger 21 to achieve heating. After releasing heat, the refrigerant can flow through the first throttle valve 251 and into the third heat exchanger 22 to absorb heat in the third heat exchanger 22. After absorbing heat, the refrigerant can flow back into the compressor 24 for compression.

[0050] Exemplarily, as Figure 6 shown, when the refrigerant circulation system 2 is in the refrigeration mode and the first heat exchanger 11 is in the heat release state, the first solenoid valve 252 is opened, the second solenoid valve 262 is closed, and the switching valve 23 is switched to the first state. The compressed refrigerant can flow out of the compressor 24 and into the third heat exchanger 22 and the first heat exchanger 11 in sequence. The refrigerant can release heat in the third heat exchanger 22 and the second heat exchanger 21, and the first heat exchanger 11 heats up. After releasing heat, the refrigerant can flow through the second throttle valve 261 and into the second heat exchanger 21. The refrigerant can absorb heat in the second heat exchanger 21 to cool the second heat exchanger 21. After absorbing heat, the refrigerant can flow back into the compressor 24 for compression.

[0051] Exemplarily, as Figure 7 shown, when the refrigerant circulation system 2 is in the heating mode and the first heat exchanger 11 is in the heat release state, the first solenoid valve 252 is opened, the second solenoid valve 262 is closed, and the switching valve 23 is switched to the second state. The compressed refrigerant can flow from the compressor 24 into the second heat exchanger 21 and release heat to heat the second heat exchanger 21. After releasing heat, the refrigerant can flow through the first throttle valve 251 and into the first heat exchanger 11 and the third heat exchanger 22 in sequence. The refrigerant can absorb heat in the first heat exchanger 11 and the third heat exchanger 22 to cool the first heat exchanger 11. After absorbing heat, the refrigerant can flow back into the compressor 24 for compression.

[0052] With the above settings, the air conditioner 100 can be flexibly switched among different modes, which is beneficial to meeting different user needs. Moreover, the switching process is stable and reliable, improving the reliability of the air conditioner 100.

[0053] In some embodiments of the present invention, the air conditioner 100 has a first air duct 13 and a second air duct 5. The first heat exchanger 11 is disposed in the first air duct 13, and the first blower 19 is used to ventilate the first air duct 13. The second heat exchanger 21 is disposed in the second air duct 5. The air conditioner 100 further includes a second blower 4 for ventilating the second air duct 5. The air conditioner 100 includes a fresh air inlet 16, a first indoor air inlet 18, and a first indoor air outlet 17 that communicate with the first air duct 13, and a second indoor air inlet 61 and a second indoor air outlet 62 that communicate with the second air duct 5.

[0054] For example, as shown in Figure 2 the air conditioner 100 has a first air duct 13 and a second air duct 5. The first air duct 13 and the second air duct 5 are arranged at intervals. For example, the first air duct 13 can be disposed at the lower part of the air conditioner 100 and the second air duct 5 can be disposed at the upper part of the air conditioner 100. The first heat exchanger 11 is disposed in the first air duct 13, and the first blower 19 is used to ventilate the first air duct 13 so that the first heat exchanger 11 can cool or heat the indoor space through the air flow in the first air duct 13. The second heat exchanger 21 is disposed in the second air duct 5. The air conditioner 100 further includes a second blower 4, and the second blower 4 is used to ventilate the second air duct 5 so that the second heat exchanger 21 can cool or heat the indoor space through the air flow in the second air duct 5.

[0055] Among them, the air conditioner 100 includes a fresh air inlet 16, a first indoor air inlet 18, and a first indoor air outlet 17. The fresh air inlet 16, the first indoor air inlet 18, and the first indoor air outlet 17 all communicate with the first air duct 13. The first blower 19 can drive fresh air to flow into the first air duct 13 from the fresh air inlet 16 and / or drive indoor air to flow into the first air duct 13 from the first indoor air outlet 17, so that the air flow can flow through the first heat exchanger 11 and flow out to the indoor space through the first indoor air outlet 17. The air conditioner 100 further includes a second indoor air inlet 61 and a second indoor air outlet 62. The second blower 4 is used to drive indoor air to flow into the second air duct 5, so that the air flow can flow through the second heat exchanger 21 and blow out to the indoor space through the second indoor air outlet 62.

[0056] Through the above settings, the interference between the second heat exchanger 21 and the first heat exchanger 11 can be avoided. Especially when one of the second heat exchanger 21 and the first heat exchanger 11 is for refrigeration and the other is for heating, the influence of the first heat exchanger 11 on the second heat exchanger 21 is reduced, improving the working reliability of the air conditioner 100.

[0057] Of course, the second heat exchanger 21 and the first heat exchanger 11 can also be arranged in the same air duct, so that the blower can ventilate the air duct. Thus, the structure of the air conditioner 100 can be simplified, which is conducive to cost reduction.

[0058] In some embodiments of the present invention, referring to Figure 8 As shown, the first heat exchanger 11 includes an independent first heat exchange part 111 and a second heat exchange part 112; the refrigerant circulation system 2 includes a second heat exchanger 21 and a third heat exchanger 22 connected in series to the second flow path S2, and a switching valve 23 for switching the flow direction of the second flow path S2. The refrigerant circulation system 2 includes a first branch S3 in parallel with the third heat exchanger 22 and a second branch S4 arranged in parallel with the second heat exchanger 21. The first heat exchange part 111 and a third solenoid valve 27 are connected in series on the first branch S3, and the second heat exchange part 112 and a fourth solenoid valve 28 are connected in series on the second branch S4.

[0059] For example, referring to Figure 8 As shown, the first heat exchanger 11 includes a first heat exchange part 111 and a second heat exchange part 112, and the first heat exchange part 111 and the second heat exchange part 112 are independent of each other. The refrigerant circulation system 2 includes a second flow path S2 and a compressor 24. The third heat exchanger 22, the third throttling valve 29 and the second heat exchanger 21 are sequentially connected in series to the second flow path S2, and the second heat exchanger 21 is located in the indoor part of the air conditioner 100 and is used to adjust the indoor temperature.

[0060] The refrigerant circulation system 2 further includes a switching valve 23, and the switching valve 23 is configured as a four-way valve. Two ports of the switching valve 23 (i.e., Figure 3 the S port and the D port in Figure 3 ) are respectively connected to both ends of the compressor 24, and the other two ports (i.e., Figure 3 the E port and the C port in ) are respectively connected to the second heat exchanger 21 and the third heat exchanger 22, so that the switching valve 23 can switch the flow direction of the second flow path S2. Specifically, the switching valve 23 can be switched to the third state, so that the refrigerant flows through the compressor 24, the third heat exchanger 22, the third throttling valve 29 and the second heat exchanger 21 in sequence, and can be switched to the fourth state, so that the refrigerant flows through the compressor 24, the second heat exchanger 21, the third throttling valve 29 and the third heat exchanger 22 in sequence.

The compressed refrigerant can flow out from the compressor 24 and into the third heat exchanger 22. The refrigerant releases heat in the third heat exchanger 22. After releasing heat, the refrigerant flows through the third throttle valve 29 and is branched to the second heat exchange part 112 and the second heat exchanger 21. The refrigerant is adapted to absorb heat in the first heat exchanger 11 and the second heat exchanger 21 to achieve cooling. After absorbing heat, the refrigerant can flow into the compressor 24 for compression.

Through the above arrangement, the first heat exchange part 111 and the second heat exchange part 112 can be evenly distributed. Whether the first heat exchange part 111 is turned on or the second heat exchange part 112 is turned on, the first heat exchanger 11 has a high temperature uniformity, which is beneficial to improving the practicability of the air conditioner 100.

[0069] In some embodiments of the present invention, the first heat exchanger 11 has a ventilation gap. The ventilation gap communicates with both sides of the thickness of the first heat exchanger 11. The first fan 19 is used to make the air flow through the ventilation gap to flow through the first heat exchanger 11, and the water supply assembly 12 is used to spray water on one surface of the first heat exchanger 11 in the thickness direction.

[0070] For example, as Figure 2 shown, the first heat exchanger 11 has a ventilation gap. The ventilation gap penetrates along the thickness direction and is used to communicate with both sides of the thickness of the first heat exchanger 11. For example, the first heat exchanger 11 can be provided with a plurality of heat exchange fins, and a ventilation gap is formed between two adjacent heat exchange fins. The first fan 19 is used to drive the air flow through the ventilation gap to flow through the first heat exchanger 11, and the water supply assembly 12 is used to spray water on one surface of the first heat exchanger 11 in the thickness direction, so that the surface of the first heat exchanger 11 is rich in moisture, and the air flow can flow out from the ventilation gap to evenly carry away the moisture on the surface of the first heat exchanger 11. Through the above arrangement, the air flow can easily carry away the moisture, which is beneficial to improving the humidification efficiency of the air conditioner 100 and improving the practicability of the air conditioner 100.

[0071] In some embodiments of the present invention, as Figure 2 shown, the central plane of the first heat exchanger 11 can be set perpendicular to the thickness direction of the first heat exchanger 11. For example, the first heat exchanger 11 can be configured as a rectangular structure, and the central plane of the first heat exchanger 11 can be set vertically or obliquely relative to the horizontal plane. Through the above arrangement, the liquid can stay on the surface of the first heat exchanger 11 more easily, so that the surface of the first heat exchanger 11 can be evenly distributed with moisture, which is beneficial to improving the humidification effect of the first heat exchanger 11 on the air flow and enhancing the humidification performance of the air conditioner 100.

[0072] In some embodiments of the present invention, the water supply assembly 12 includes a water storage box 121, a water pump 122, and a water distributor 123. The water distributor 123 is provided at the upper end of the first heat exchanger 11 and has a plurality of water spraying holes 1231. The water pump 122 is used to pump the water in the water storage box 121 to the water distributor 123. The water storage box 121 includes a water receiving tank 1211 located at the lower end of the first heat exchanger 11. The air conditioner 100 further includes a water tank 3 for supplying water to the water storage box 121.

[0073] For example, with reference to Figures 9 - 12 As shown, the water supply assembly 12 includes a water storage box 121, a water pump 122, a water distributor 123, and a water pipe 124. The water distributor 123 is provided at the upper end of the first heat exchanger 11. The water distributor 123 is configured in a groove shape and is provided with a water inlet hole 1232. The water pump 122 is communicated with the water inlet hole 1232 through the water pipe 124, so that the water pump 122 can pump the water in the water storage box 121 to the water distributor 123 through the water pipe 124.

[0074] The lower side wall of the water distributor 123 has a plurality of water spraying holes 1231. The plurality of water spraying holes 1231 are arranged at intervals along the length direction of the water distributor 123. The water pumped into the water storage box 121 can respectively fall onto the first heat exchanger 11 through the plurality of water spraying holes 1231 to wet the first heat exchanger 11. The water storage box 121 includes a water receiving tank 1211. The water receiving tank 1211 is located at the lower end of the first heat exchanger 11. The water receiving tank 1211 is used to receive the water flowing down from the first heat exchanger 11 for secondary utilization. The air conditioner 100 further includes a water tank 3. The water tank 3 is provided with a water valve. The water tank 3 is used to selectively supply water to the water storage box 121 through the water valve. Thus, the air conditioner 100 can provide stable and uniform water supply to the first heat exchanger 11, improving the reliability of the air conditioner 100.

[0075] Preferably, the central plane of the first heat exchanger 11 can be set to be inclined relative to the horizontal plane, so that the heights on both sides of the first heat exchanger 11 are different. The water distributor 123 is provided at the upper end of the high side of the first heat exchanger 11. The water distributor 123 can supply water downward through the water spraying holes 1231, and the water falling onto the first heat exchanger 11 can flow downward along the first heat exchanger 11 to the low side of the first heat exchanger 11.

[0076] In some embodiments of the present invention, the air handling component 1 is a fresh air component 10 and defines a first air duct 13. The first heat exchanger 11 is provided in the first air duct 13. The first fan 19 is used to ventilate the first air duct 13. The fresh air component 10 further includes a first purification component 14 provided in the first air duct 13 and located upstream of the first heat exchanger 11.

[0077] For example, with reference to Figure 1 、Figure 2 and Figure 10 As shown in Figure 10 , the air handling component 1 is the fresh air component 10. A first air duct 13 is defined inside the fresh air component 10. Both the first fan 19 and the first heat exchanger 11 are arranged inside the first air duct 13. The first fan 19 is used to ventilate the first air duct 13, that is, the first fan 19 can make the first air duct 13 suck in fresh air and / or indoor air and blow it into the indoor space. The fresh air component 10 further includes a first purification assembly 14. The first purification assembly 14 is arranged inside the first air duct 13. The first purification assembly 14 is located upstream of the first heat exchanger 11, so that the air flow inside the first air duct 13 can flow through the first purification assembly 14 and the first heat exchanger 11 in sequence. The first purification assembly 14 is used to purify the air flow, so that the first heat exchanger 11 is protected from pollution. It should be noted that the first purification assembly 14 can be a HEPA net or a plasma grid, and the present application does not limit this.

[0078] Through the above settings, the first heat exchanger 11 can be protected, the probability of bacteria breeding and impurity precipitation on the first heat exchanger 11 is reduced, which is beneficial to protecting the health of users and improving the practicability of the air conditioner 100.

[0079] In some embodiments of the present invention, as Figure 2 shown, the first fan 19 can be arranged upstream of the first heat exchanger 11, the first purification assembly 14 is arranged between the first fan 19 and the first heat exchanger 11, and the fresh air component 10 further includes a second purification assembly 15. The second purification assembly 15 is arranged upstream of the first fan 19. Specifically, when the fresh air component 10 starts to work, the first fan 19 operates, and the air flow can flow into the first air duct 13. The air flow flows along the first air duct 13 to the second purification assembly 15 for preliminary purification. The preliminarily purified air flow flows through the first fan 19 to flow to the first purification assembly 14. The first purification assembly 14 is used to perform secondary purification on the air flow. The secondarily purified air flow can flow through the first heat exchanger 11 to flow into the indoor space.

[0080] Through the above settings, the air flow can be fully purified to protect the first fan 19 and the first heat exchanger 11 from pollution. In particular, the first heat exchanger 11 can be protected, and the probability of bacteria breeding and impurity precipitation on the first heat exchanger 11 is greatly reduced, protecting the health of users.

[0081] In some embodiments of the present invention, as Figure 2 shown, the first purification assembly 14 can be arranged in parallel with the first heat exchanger 11. Thus, the space inside the air conditioner 100 can be fully utilized, which is beneficial to increasing the areas of the first purification assembly 14 and the first heat exchanger 11, improving the humidification effect and the purification effect, and improving the practicability of the air conditioner 100.
