Problems solved by technology

[0003] The existing air conditioning humidification method is generally to install a water spray device on one side of the heat exchanger. This setting method is not conducive to the evaporation of water, and it is easy to cause the phenomenon of "blowing water". The humidification efficiency is low, which affects the comfort of use.

Embodiment 1

[0045] The present invention provides an air conditioner indoor unit, which includes a fan 1, a water spray device 2 and a heat exchange device. The heat exchange device includes a first heat exchange unit 31 and a second heat exchange unit 32. On the air path of the fan 1, the first The heat exchange unit 31 is at least partially located on the upstream side of the water spray device 2 , and the second heat exchange unit 32 is at least partially located on the downstream side of the water spray device 2 . The first heat exchange unit 31 can make the wind sent by the fan more uniform and stable, which is more conducive to the full mixing of the air and the water sprayed by the water spray device 2, and improves the humidification efficiency. The second heat exchange unit 32 can block the unevaporated water in the air. Large particles of water droplets, so as to avoid the phenomenon of "blowing water".

Embodiment 2

[0057] The present invention also provides an air conditioner, including the air conditioner indoor unit as described above, capable of achieving a good humidification effect.

[0058] Method example:

[0059] The invention also provides a control method of the air conditioner indoor unit. The air-conditioning indoor unit includes a fan 1, a water spray device 2, a first heat exchange unit 31 and a second heat exchange unit 32. On the air path of the fan 1, the first heat exchange unit 31 is located on the water spray device 2. On the upstream side of the water spray device 2, the second heat exchange unit 32 is located on the downstream side. When the indoor unit of the air conditioner is performing humidification, the water spray device is turned on when the fan 1 is blowing air. The water is fully mixed, and then blown out through the second heat exchange unit, which can block the unevaporated large particles of water droplets in the air, thereby avoiding the phenomenon o...

Abstract

The invention discloses an indoor unit of an air conditioner, a control method and the air conditioner. The indoor unit of the air conditioner comprises a fan, a water spray device and heat exchange devices. The heat exchange devices comprise a first heat exchange unit and a second heat exchange unit; and on an air way of the fan, the first heat exchange unit is at least partially located on the upstream side of the water spray device, and the second heat exchange unit is at least partially located on the downstream side of the water spray device. Meanwhile, the invention provides the control method of the indoor unit of the air conditioner, and the air conditioner. According to the indoor unit of the air conditioner provided by the invention, the heat exchange devices are respectively arranged on the upstream side and the downstream side of the water spray device; the first heat exchange unit on the upstream side can enable air supplied from the fan to be more uniform and stable, so that air and water sprayed from the water spray device can be fully mixed favorably, and the humidification efficiency is improved; and the second heat exchange unit on the downstream side can block unevaporated large-particle water drops in the air, so that the phenomenon of 'water blowing' is avoided.

Description

technical field [0001] The invention relates to the technical field of air conditioners, and more specifically relates to an air conditioner indoor unit, a control method and an air conditioner. Background technique [0002] At present, household air conditioners mainly control the ambient temperature, and less attention is paid to the influence of air humidity on the thermal comfort of the human body. For example, people in the south are used to humid air. When the air conditioner cools in summer, it will cause a large amount of water loss in the air, causing discomfort to the human respiratory system; The relative humidity is lower, which can cause chapped lips and damage to the mucous membrane of the respiratory tract. Therefore, the air conditioner needs to have a humidification function. [0003] The existing air conditioning humidification method is generally to install a water spray device on one side of the heat exchanger. This installation method is not conducive t...
