In order to accurately determine the amount of humidification water required in the room, the present embodiment provides an implementation of determining the target humidification amount based on the detection value of the first flowmeter and the target temperature and target humidity set by the user, and specifically, the following steps 1) to 4 may be referred to:

step 1): the initial water quality in the room where the humidifying air conditioner is located is obtained.

When the air conditioner is detected to enter the temperature-adjusting humidifying mode, the first flowmeter and the second flowmeter are controlled to reset to zero, the inner fan is controlled to start and operate, the current indoor environment temperature and the current air humidity are detected, and the initial temperature and the initial humidity are obtained. When the humidifying air conditioner just enters a temperature-adjusting humidifying mode, the humidifier is not started, the humidity value detected by the humidity sensor cannot be influenced by the humidifier, the current indoor environment temperature is detected based on the temperature sensor and is recorded as the initial temperature, and the humidity of the air conditioner is detected based on the humidity sensor and is recorded as the initial humidity. By controlling the first flowmeter and the second flowmeter to reset to zero, the amount of condensed water and the amount of humidifying water after the humidifying air conditioner enters the temperature-adjusting humidifying mode can be accurately detected.

Inquiring the mass ratio of water in the air corresponding to the initial temperature and the initial humidity from a preset humid air enthalpy diagram; and acquiring the air volume and the dry air density of the room in which the humidifying air conditioner is positioned. Referring to the psychrometric chart of the humid air as shown in fig. 2, the mass ratio of water in the air corresponding to the initial temperature and the initial humidity is searched from the psychrometric chart of the humid air (which may also be a psychrometric table of the humid air), the indoor air volume input by the user is received, and the dry air density is obtained, and the dry air density is usually ρ ═ 1.29 g/L.

And calculating the product of the mass ratio of the water in the air corresponding to the initial temperature and the initial humidity, the dry air density and the air volume to obtain the indoor initial water mass. The calculation of the indoor initial water mass M1 is: m1 ρ ν a1, v is the indoor air volume, and a1 is the mass ratio of water in the air corresponding to the initial temperature and the initial humidity.

By acquiring the initial temperature and the initial humidity when the indoor air enters the temperature-adjusting and humidifying mode, the mass ratio of water in the current air can be quickly inquired, the initial water mass when the indoor air enters the temperature-adjusting and humidifying mode can be accurately calculated, and a reliable basis is provided for controlling the indoor air humidity.

Step 2): and acquiring a target temperature and a target humidity set by a user, and determining the indoor target water quality based on the target temperature and the target humidity.

And inquiring the mass ratio of water in the air corresponding to the target temperature and the target humidity from a preset humid air enthalpy diagram. And acquiring the target temperature and the target humidity input by the user, and if the target humidity is not set by the user, determining that the target humidity is the target humidity set last time or the default value Ws is 50%. And searching the mass ratio of water in the air corresponding to the target temperature and the target humidity from the preset humid air enthalpy diagram.

And calculating the product of the mass ratio of the water in the air corresponding to the target temperature and the target humidity, the dry air density and the air volume to obtain the indoor target water mass. Calculating the water mass in the indoor air at the target temperature and the target humidity set by the user, and recording the water mass as the target water mass, wherein the calculation formula of the target water mass Ms is as follows: ms is ρ × v × a2, where a2 is the mass ratio of water in the air corresponding to the target temperature and the target humidity.

Through calculating the target water quality in the air under target temperature and target humidity, can be with the quality of water volume control in the room air can satisfy user's demand at target water quality, at the in-process of control air humidity, need not to detect room air humidity based on humidity transducer, avoided because of the inaccurate humidity control precision that influences of air humidity detection.

Step 3): and calculating the difference between the initial water quality and the target water quality to obtain the water amount to be removed.

In order to enable the water quality in the indoor air to reach the target water quality, the difference value between the initial water quality and the target water quality in the indoor is calculated, the quality of the water needing to be removed in the indoor when the target water quality is achieved can be obtained, and the water removal amount delta M is M1-Ms.

Step 4): and calculating the difference between the current detection value of the first flow meter and the water to be removed to obtain the target humidification amount.

The method comprises the steps of obtaining a detection value of a current first flowmeter to obtain current generated condensate water flow, calculating a difference value between the current detection value of the first flowmeter and water to be removed, obtaining indoor required humidification water amount when the target humidity is reached, and recording the indoor required humidification water amount as target humidification amount ms, wherein ms is M-delta M, and M is the current detection value of the first flowmeter, namely the current condensate water flow. When the flow of the condensed water is large, the indoor air is drained more, the water content in the air is reduced, and the indoor air needs to be humidified to supplement water.

Through when the air conditioner gets into the humidification mode that adjusts the temperature, acquire indoor initial water quality and target water quality, can accurately calculate and obtain indoor water quantity of waiting to remove, because the air conditioner operation in-process can constantly produce the comdenstion water, through calculating the detected value of first flowmeter and waiting to remove the difference of water quantity, can accurately calculate and obtain indoor required target humidification volume, promoted the accuracy that the humidification water quantity calculated.

In practical applications, taking a 1.5P indoor unit of an air conditioner as an example, in a room with a size of 6m × 3m and a volume of V54 m3, when the air conditioner enters the temperature-adjusting and humidifying mode, the initial ambient temperature is maintained at T1 ═ 30 ℃, the initial humidity is maintained at W1 ═ 65%, the set temperature input by the user is 25 ℃, and the set humidity is 50%.

As can be seen from an examination of the psychrometric chart of the humid air, the mass ratio of water in the air with the initial temperature of 30 ℃ and the initial humidity of 65% (i.e., the mass content of the humid air water) is a1 ═ 17g/kg, the dry air density is 1.29g/L, and when the air enters the temperature-adjusting humidification mode, the indoor initial water mass M1 ═ ρ × v × a1 ═ 1184g, i.e., the water mass in the air is 1184 g.

As can be seen from the query of the psychrometric chart of the humid air, the mass ratio of water in the air (i.e., the mass content of the humid air water) corresponding to the set temperature of 25 ℃ and the set humidity of 50% is a2 ═ 10g/kg, the target water mass Ms ═ ρ × v ═ a2 ═ 696g, and it is only necessary to control the water mass in the air to be near 696 g.

The water removal amount is: Δ M-M1-Ms 1184g-696 g-488 g.

The target humidification amount is: and ms is M-Delta M. If the current detection value of the first flowmeter is M100 g, and ms 388g, it indicates that 388g of water removal is needed, and the indoor unit continues to generate condensed water to reduce the water quality in the air without turning on the humidifier.

In order to accurately control the indoor air humidity to be always kept at the target humidity, the present embodiment provides an implementation manner for controlling the evaporation water amount of the humidifier of the humidification air conditioner based on the detection value of the first flow meter, the detection value of the second flow meter and the target humidification amount, and the implementation manner can be specifically executed with reference to the following steps (1) to (2):

step (1): and when the target humidification amount is larger than zero, controlling the humidifier to start running.

When the calculated target humidification amount is larger than zero, it indicates that the current indoor air humidity is smaller than the target humidity set by the user, more condensed water is generated by the indoor unit, more water discharge of the indoor air is generated, and the humidifier needs to be started to supplement the water quality in the air to reach the target humidity.

Step (2): the power of the humidifier is subjected to proportional differential adjustment based on the detection value of the first flow meter, the detection value of the second flow meter, and the target humidification amount.

And in the operation process of the air conditioner, the detection value of the first flowmeter and the detection value of the second flowmeter are periodically acquired, and the operation power of the humidifier is subjected to proportional differential adjustment, so that the humidification rate of the humidifier is controlled.

The power of the humidifier is subjected to proportional differential adjustment, so that the humidification rate of the humidifier can be controlled, the power of the humidifier is controlled based on the detection value of the first flowmeter, the detection value of the second flowmeter and the target humidification amount, the humidification rate of the humidifier can be dynamically adjusted according to the flow rate of condensed water and the humidification water amount, the closed-loop control of the indoor air humidity is realized, and the humidity control precision is improved.

In a specific embodiment, the power increment of the humidifier is calculated by the following equation: Δ P is Ka (ms-M (k)) + Kb [ M (k)) + M (k) -M (k-1) ], where Δ P is the power increment of the humidifier, ms is the target humidification amount, M (k) is the detection value of the second flow meter at the current period k, M (k) is the detection value of the first flow meter at the current time k (i.e., the detection value of the first flow meter at the current period t), M (k-1) is the detection value of the first flow meter at the previous time k-1 (i.e., the detection value of the first flow meter at the previous period t-1), Ka and Kb are both proportionality coefficients, and Ka 1/5 and Kb 1/2.

And when the power increment delta P of the humidifier is calculated, the power of the humidifier is adjusted based on the power increment delta P, so that the humidification rate of the humidifier is controlled, and the indoor air humidity is kept near the target humidity. And after the humidifier operates for a second preset time (such as 60-90 s) after the power is adjusted, returning to the step of determining the target humidification amount based on the detection value of the first flow meter and the target temperature and the target humidity set by the user, so as to calculate a new target humidification amount according to the current detection value of the first flow meter, and realizing the circulation control of the air humidity.

In a specific embodiment, when the target humidification amount is less than zero, the humidifier is controlled to stop operating, and when the humidifier stops operating for a first preset time period, the step of determining the target humidification amount based on the detection value of the first flow meter and the target temperature and the target humidity set by the user is returned to be executed.

When the calculated target humidification amount is less than zero, it indicates that the current indoor air humidity is greater than the target humidity, the indoor air needs to be dewatered without humidifying the indoor air, the humidifier is controlled to keep a state of stopping operation, the indoor unit normally operates to generate condensed water, the indoor air humidity is reduced, and after a first preset time (such as 60-90 s), the step of determining the target humidification amount based on the detection value of the first flowmeter and the target temperature and the target humidity set by the user is returned to be executed, so that the target humidification amount is recalculated according to the updated condensed water flow.

According to the control method of the humidifying air conditioner, the power of the humidifier is subjected to proportional differential control according to the flow of the condensed water and the flow of the humidifying water, the humidifier does not need to be adjusted according to the humidity value detected by the humidity sensor, the accurate control of the indoor humidity is realized, and the robustness of humidity adjustment is improved.
