Specifically, the host 10 is mainly used for realizing conventional cooling and heating functions of the air duct machine.

The wet film assembly 22 is mainly composed of a wet film, the wet film has good water absorption, a uniform water film can be formed after the wet film absorbs water from the humidifying water receiving tank 23a, and when the dry air flow passes through the wet film after water absorption, the water molecules can fully absorb heat in the air flow to be vaporized and evaporated, so that a moist air flow is formed.

An airflow path is formed between the first air inlet and the first air outlet 11a, and the airflow path is a path through which external airflow flows in the accommodating cavity after entering the accommodating cavity from the first air inlet in a refrigerating or heating mode, that is, the external airflow enters the accommodating cavity from the first air inlet under the action of the air conditioning fan assembly in the refrigerating or heating mode, at least part of the external airflow flows along the airflow path, exchanges heat with the heat exchanger 12 when flowing through the heat exchanger 12, and flows out of the first air outlet 11 a.

Depending on the type of ductwork, the relative position between the air conditioning fan assembly and the heat exchanger 12 may be adjusted, for example, the heat exchanger 12 may be located upstream of the air conditioning fan assembly in the airflow direction, that is, after the air conditioning fan assembly draws the external airflow into the receiving chamber, the airflow flows through the heat exchanger 12 and then through the air conditioning fan assembly, which type of ductwork is also referred to as an induced draft ductwork. The heat exchanger 12 may also be located downstream of the air conditioning fan assembly in the airflow direction, that is, the air conditioning fan assembly first sucks the external airflow into the air conditioning fan assembly, and then blows the airflow toward the heat exchanger 12, which is equivalent to the airflow flowing through the air conditioning fan assembly first and then through the heat exchanger 12, and this type of air duct machine is also referred to as a blowing type air duct machine.

Specifically, there may be various ways of communicating the humidification water receiving tank 23a with the air conditioning water receiving tank 13a, as long as condensed water in the air conditioning water receiving tank 13a can flow into the humidification water receiving tank 23a, for example, referring to fig. 4 to 6, a drain pipe 23c may be provided on the humidification water receiving tank 23, a water flow inlet of the drain pipe 23c communicates with the air conditioning water receiving tank 13a, a water outflow opening of the drain pipe 23c communicates with the humidification water receiving tank 23a, for example, an end of the drain pipe 23c having a water flow inlet may protrude to the outside of the humidification water receiving tank 23, and meanwhile, an installation opening communicating with the air conditioning water receiving tank 13a is provided on the air conditioning water receiving tank 13, through holes are provided on the casing 11 and the housing 21, respectively, and an end of the drain pipe 23c having a water flow inlet is connected with the installation opening on the air conditioning water receiving tank 13a after passing through the through holes on the casing 11 and the housing 21.

In one embodiment, referring to fig. 5, the distance H between the lowest point of the water outlet of the drain pipe 23c and the lowest point of the bottom wall of the humidifying water receiving tank 23a may be greater than or equal to 30mm to ensure that the condensed water can flow into the air-conditioning water receiving tank 13 a.

In one embodiment, referring to fig. 5 and 6, the second air inlet 21a is opposite to the second air outlet 21b, and the bottom wall of the humidifying water-receiving tank 23a has a horizontal wall surface 23e, a first inclined wall surface 23f and a second inclined wall surface 23g; the first inclined wall surface 23f is provided on the side of the horizontal wall surface 23e close to the second air inlet 21a, the first inclined wall surface 23f is inclined upward from the side connected with the horizontal wall surface 23e to the side close to the second air inlet 21a, the second inclined wall surface 23g is provided on the side of the horizontal wall surface 23e close to the second air outlet 21b, the second inclined wall surface 23g is inclined upward from the side connected with the horizontal wall surface 23e to the side close to the second air outlet 21b, and the wet film assembly 22 is located on the upper side of the horizontal wall surface 23 e.

s402: controlling the water adding pump according to a preset strategy;

s403: opening an air valve;

s404: and starting the humidifying fan assembly.

Wherein, step S402 and step S403 are not consecutive, and when step S403 is located after step S402, step S403 and step S404 are not consecutive either.

That is, in the heating mode, when humidification is desired, the damper 30 may be opened to allow a portion of the air flow from the first air inlet into the receiving chamber to pass through the wet membrane module 22 in the humidification chamber after heat exchange by the humidifying blower assembly 24 through the heat exchanger 12.

Specifically, the float switch 27 may be used to detect the water level in the humidification water receiving tank 23a, and if the water level in the humidification water receiving tank 23a is lower than the set water level, this means that there is no water in the humidification water receiving tank 23a or the amount of water in the humidification water receiving tank 23a is insufficient for humidification, and therefore, the water supply pump needs to be turned on to supply water to the humidification water receiving tank 23 a.

The current ambient humidity may be detected by a humidity sensor, and the user sets the humidity to the humidity set by the user as desired.

The current ambient humidity can be used

Representation +.>

The flow rate of the water adding pump may be determined as needed, and the flow rate of the water adding pump may be 200L-500L/min, for example.

By controlling the operation time of the water pump according to the difference between the user-set humidity and the current ambient humidity and the preset rule set, the amount of water added to the humidifying water receiving tank 23a can be controlled, and thus, different humidifying demands can be satisfied.

If the water level in the humidification water receiving tank 23a is equal to or higher than the set water level, it means that there is enough water in the humidification water receiving tank 23a for humidification, and at this time, the step S403 and the step S404 may be directly performed without turning on the water pump.

In one embodiment, after turning on the humidifying blower fan assembly, the control method further comprises: if the water level in the humidifying water receiving tank is lower than the set water level and the current ambient humidity does not reach the user set humidity, the humidifying fan assembly is turned off, the difference between the user set humidity and the current ambient humidity is calculated, the working time of the water adding pump is determined according to the difference and a preset rule, the water adding pump is turned on, the water adding pump is controlled according to the determined working time, and the humidifying fan assembly is turned on.

Specifically, a water level in the humidification water receiving tank 23a lower than the set water level indicates that the current amount of water in the humidification water receiving tank 23a is too small to meet the humidification requirement, and a current ambient humidity not reaching the user set humidity indicates that the current ambient humidity has not reached the user set humidity, so that the humidification fan assembly 24 may be turned off, and the water pump is turned on again to supplement water to the humidification water receiving tank 23a according to the difference between the user set humidity and the current ambient humidity and the preset rule described in the previous embodiment, which is equivalent to executing the water adding operation described in the previous embodiment again, and after the water adding is completed, the humidification fan assembly 24 is turned on again to continue humidification.
