Example fifteen
As shown in fig. 1 to 18, according to an embodiment of the present invention, the indoor unit 1 of an air conditioner includes a cross-flow fan 132, a jet nozzle 134, a heat exchanger, a partition 106, and a water receiving tank. When the fan 132 is turned on, air enters the casing 10 through the jet air inlet 142, enters the fan 132 through the first heat exchanging portion 11, and is supplied to the space between the second heat exchanging portion 12 and the rear plate 102 through the jet nozzle 134. The high-speed airflow ejected from the jet nozzle 134 causes the space between the second heat exchanging part 12 and the third heat exchanging part 15 and the back plate 102 to form a low-pressure region, so that the air in the environment is sucked, enters the housing 10 from the main air inlet 144, is cooled by the second heat exchanging part 12 and the third heat exchanging part 15, and finally enters the room through the air outlet 16.
Fig. 2 and 5 show an arrangement of the fan 132, the jet nozzle 134, and the heat exchanger, in which the first heat exchanging portion 11 and the third heat exchanging portion 15 are parallel to the back plate 102, the cross-flow fan 132 is arranged between the first heat exchanging portion 11 and the back plate 102, and the first heat exchanging portion 11 and the cross-flow fan 132 are both disposed above the partition plate 106. An included angle is formed between the second heat exchanging portion 12 and the back plate 102, one end of the second heat exchanging portion 12 is connected to the third heat exchanging portion 15, and the other end is close to the jet nozzle 134. The length of the indoor air conditioner 1 in the first direction is H, the length in the second direction is W, and the length in the third direction is L. Wherein H ranges from 250mm to 500mm, L ranges from 900mm to 1500mm, and W ranges from 90mm to 200 mm.
Specifically, the air conditioning indoor unit 1 has at least two operation modes, namely, a strong wind mode (e.g., active supply air jet) and a natural wind mode (e.g., fully passive natural convection). In the strong wind mode, air enters the fan 132 after passing through the first heat exchanging portion 11, and is supplied to the space between the second heat exchanging portion 12 and the rear panel 102 through the jet nozzle 134. The high-speed airflow from the jet nozzle 134 forms a low-pressure region in the space between the second heat exchanging part 12, the third heat exchanging part 15 and the back plate 102, so that the air in the environment is sucked, enters the housing 10 from the main air inlet 144, is cooled by the second heat exchanging part 12 and the third heat exchanging part 15, and is finally delivered into the room through the air outlet 16.
Furthermore, when the air conditioner is in a strong wind mode, heating operation can be carried out, at the moment, the temperature of the working medium in the heat exchanger is higher, and the guided air is heated by the heat exchanger and then mixed with jet air to be sent into a room.
In the natural wind mode, the fan 132 is turned off, the indoor return air enters the casing 10 from the main air inlet 144, and enters the second heat exchanging portion 12 and the third heat exchanging portion 15 for heat exchange, the cooled cold air flows out from the air outlet 16 and is sent into the room under the action of gravity due to the increase of density, and the indoor hot air enters again in the form of return air, so that the air circulation is completed.

In order to prevent the condensed water on the second heat exchanging portion 12 from dripping into the room from the air outlet 16, the second heat exchanging portion 12 is inclined at an angle α1The value range is 10 degrees to 45 degrees, and the inclination angle alpha of the jet nozzle 1342The value range is more than or equal to 5 degrees and less than or equal to alpha2≤α1The third heat exchanging portion 15 is parallel to the first direction, and an angle between the third heat exchanging portion 15 and the second direction is ± 10 ° in order to maintain a certain installation error. In order to improve the natural convection effect, the ratio of the distance between the two fins of the second heat exchanging portion 12 and the third heat exchanging portion 15 to the width of a single fin is in a range of 0.1 to 0.45.
Further, when the fan 132 is activated, the air passes through the first heat exchanging part 11 by the suction force of the fan 132 and exchanges heat with the first heat exchanging part 11. Therefore, in order to ensure sufficient temperature reduction of the air in the first cavity 1012, the fin pitch of the first heat exchanging portion 11 may be made smaller than the second heat exchanging portion 12 and the third heat exchanging portion 15, and the fin width may be made wider than the second heat exchanging portion 12 and the third heat exchanging portion 15. Specifically, the distance between two adjacent fins of the first heat exchanging portion 11 and the indirect ratio between two adjacent fins of the second heat exchanging portion 12 or the third heat exchanging portion 15 range from 0.3 to 0.8, and the ratio between the width of the fins of the first heat exchanging portion 11 and the width of the fins of the second heat exchanging portion 12 or the third heat exchanging portion 15 ranges from 1 to 4.
