Referring to fig. 1 to 4 and 7, an embodiment of the present application provides a duct type air conditioner, which includes a main unit 10, a humidification module 20, and an air valve 30; the host 10 comprises a casing 11, a heat exchanger 12 and an air conditioner fan assembly, wherein the casing 11 is provided with an accommodating cavity, and a first air inlet and a first air outlet 11a which are communicated with the accommodating cavity, and the heat exchanger 12 and the air conditioner fan assembly are arranged in the accommodating cavity and positioned on a first air flow circulation path formed between the first air inlet and the first air outlet 11 a; the humidifying module 20 is arranged at one side of the main machine 10, the humidifying module 20 comprises a shell 21 and a wet film component 22, the humidifying device comprises a humidifying fan assembly 24 and a humidifying water pan 23 with a humidifying water receiving groove 23a, wherein the shell 21 is provided with a humidifying cavity communicated with the accommodating cavity, and a second air inlet 21a and a second air outlet 21b communicated with the humidifying cavity, a first airflow humidifying path passing through the heat exchanger 12 and the communication part of the humidifying cavity and the accommodating cavity is formed between the first air inlet and the second air outlet 21b, a second airflow humidifying path partially overlapped with the first airflow humidifying path is formed between the second air inlet 21a and the second air outlet 21b, the wet film assembly 22 and the humidifying fan assembly 24 are arranged in the humidifying cavity and positioned in the overlapped area of the first airflow humidifying path and the second airflow humidifying path, and partial area of the wet film assembly 22 can extend into the humidifying water receiving groove 23 a; a damper 30 is provided in the humidification chamber in communication with the receiving chamber to selectively open or close the first airflow humidification path.
Another embodiment of the present application provides an air conditioner including the duct unit provided in any one of the embodiments of the present application.
Specifically, the main unit 10 is mainly used to implement the conventional cooling and heating functions of the duct machine.
The wet film assembly 22 is mainly composed of a wet film having good water absorbability, and the wet film can form a uniform water film after absorbing water from the humidification water receiving tank 23a, and when dry air flow passes through the wet film after absorbing water, water molecules can sufficiently absorb heat in the air flow to be vaporized and evaporated, thereby forming wet air flow.
An airflow circulation path is formed between the first air inlet and the first air outlet 11a, and in the cooling or heating mode, after external airflow enters the accommodating cavity from the first air inlet, the external airflow flows in the accommodating cavity and flows out from the first air outlet 11a, that is, in the cooling or heating mode, after the external airflow enters the accommodating cavity from the first air inlet under the action of the air conditioner fan assembly, at least part of the airflow flows along the airflow circulation path, and after exchanging heat with the heat exchanger 12 when flowing through the heat exchanger 12, the external airflow flows out from the first air outlet 11 a.
The relative position between the air conditioner fan assembly and the heat exchanger 12 can be adjusted according to the type of the air duct machine, for example, the heat exchanger 12 can be located at the upstream of the air conditioner fan assembly along the airflow flowing direction, that is, after the air conditioner fan assembly sucks the outside airflow into the accommodating cavity, the airflow firstly flows through the heat exchanger 12 and then flows through the air conditioner fan assembly, and this type of air duct machine is also called a suction air duct machine. The heat exchanger 12 may also be located downstream of the air conditioner fan assembly along the airflow flowing direction, that is, the air conditioner fan assembly first sucks the external airflow into the air conditioner fan assembly, and then blows the airflow to the heat exchanger 12, which is equivalent to the airflow flowing through the air conditioner fan assembly first and then through the heat exchanger 12, and this type of air duct machine is also called a blowing type air duct machine.
The first airflow humidifying path and the second airflow humidifying path are both flow paths of the air duct machine in a humidifying mode, external airflow flows through the wet film assembly 22 in the air duct machine, specifically, when the air valve 30 is opened, a part of the external airflow flows along the first airflow humidifying path, the other part of the external airflow flows along the second airflow humidifying path, that is, a part of the external airflow entering the accommodating cavity from the first air inlet flows through the heat exchanger 12 under the action of the humidifying fan assembly 24, enters the humidifying cavity from a communication part of the humidifying cavity and the accommodating cavity, flows out from the second air outlet 21b after the wet film assembly 22 is humidified, a part of the external airflow enters the humidifying cavity from the second air inlet 21a, flows out from the second air outlet 21b after the wet film assembly 22 is humidified, when the air valve 30 is closed, the external airflow enters the humidifying cavity only from the second air inlet 21a, and flows out from the second air outlet 21b after being humidified at the wet film assembly 22, that is, when the air valve 30 is opened, the first air flow humidification path is turned on, a part of the air flow passing through the wet film assembly 22 flows along the first air flow humidification path, another part of the air flow passes along the second air flow humidification path, and when the air valve 30 is closed, the first air flow humidification path is turned off, and the air flow passing through the wet film assembly 22 only flows along the second air flow humidification path.
The humidifying fan assembly 24 shown in fig. 3 is disposed downstream of the wet film assembly 22 in the airflow flowing direction, that is, the airflow entering the humidifying chamber flows through the wet film assembly 22 first and then flows through the humidifying fan assembly 24, so that the amount of air supplied to the second air outlet 21b by the humidifying fan assembly 24 can be increased, and in some embodiments, the humidifying fan assembly 24 can also be disposed upstream of the wet film assembly 22 in the airflow flowing direction.
