[0002] Currently, with the continuous improvement of living standards, people have higher and higher requirements for indoor environmental comfort. However, when air conditioners are cooling, they reduce the humidity of the indoor environment, making users feel that the indoor air is dry. At the same time, since the air humidity is already relatively low in winter, when air conditioners are heating, users will also feel that the indoor air is hot and uncomfortable.

[0003] In response to the above situation, air conditioner manufacturers have successively launched air conditioners with humidification functions.

[0014] Furthermore, in step S4, if △d 预设2 ≤d 内 ≤△d 预设1 If d 内 <△d 预设2 If so, adjust the speed of the fresh air fan to the highest setting.

The illustrative embodiments of the invention and their descriptions are used to explain the invention and do not constitute an undue limitation of the invention. In the drawings: Figure 1 A flowchart illustrating an embodiment of the humidification method for a fresh air conditioner according to the present invention is shown. Detailed Implementation

[0023] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0024] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0025] In this invention, unless otherwise stated, directional terms such as "up" and "down" are generally used in relation to the direction shown in the accompanying drawings, or in relation to the vertical, perpendicular, or gravitational direction; similarly, for ease of understanding and description, "left" and "right" are generally used in relation to the left and right shown in the accompanying drawings; "inner" and "outer" refer to the inner and outer contours of each component itself, but the above directional terms are not intended to limit this invention.

[0026] To address the issues of difficult maintenance and negative impact on user experience associated with air conditioners that have humidifiers installed in existing technologies, this application provides a humidification method for a fresh air conditioner and a fresh air conditioner itself.

[0027] like Figure 1 As shown, the humidification methods for fresh air conditioners include: Step S1: Obtain the start / stop status of the fresh air unit of the fresh air air conditioner; Step S2: After determining that the fresh air device has been activated, obtain the rate of change V of indoor CO2 gas concentration. A Based on the concentration change rate V A and the first preset concentration change rate ΔV A预设1 The second preset concentration change rate ΔV A预设2 Adjust the speed of the fresh air fan according to the relationship between them; If the fresh air system is determined to be off, activate it and obtain the indoor humidity level (d). 内 According to the indoor humidity d 内 and the first preset humidity △d 预设1 Second preset humidity △d 预设2 Adjust the speed of the fresh air fan according to the relationship between them.

[0028] By applying the technical solution of this embodiment, the function of introducing fresh outdoor air into the air conditioner to supplement and adjust the humidity of indoor air is achieved, thereby realizing the waterless humidification function of the air conditioner. This solves the problem that the subsequent maintenance of air conditioners with humidifiers is difficult and affects the user experience in the prior art, so as to avoid users feeling dry air during the use of the air conditioner and improve user comfort.

[0029] In this embodiment, the rate of change of CO2 gas concentration V A The rate of change of CO2 concentration at the current moment compared to the CO2 concentration at the initial moment when the fresh air fan was turned on; the first preset concentration change rate ΔV A预设1 The second preset concentration change rate ΔV is the maximum acceptable rate of change in indoor air CO2 concentration. A预设2 The preset minimum rate of change in acceptable indoor air CO2 concentration; the first preset humidity Δd 预设1 The preset acceptable maximum indoor air humidity; the second preset humidity Δd 预设2 This is the preset minimum acceptable indoor air humidity level.

[0030] In this embodiment, the air conditioner does not require additional humidification devices or moisture-absorbing materials. It directly utilizes fresh air introduced from outdoors to regulate the humidity of the indoor air, achieving waterless humidification and solving the problem of dry indoor air during air conditioning use.

[0031] In this embodiment, the system checks whether the fresh air fan is working before the user turns on the humidification function. If the fresh air fan is already working, it indicates that the user feels the indoor air quality is poor and stuffy, and has chosen to turn on the fresh air. Under this condition, determining the indoor CO2 concentration takes precedence over determining the indoor humidity. The control program prioritizes satisfying the user's adjustment of the indoor CO2 concentration using fresh air, then detects the current indoor CO2 concentration and calculates the rate of change V of the CO2 concentration. A Detect indoor air humidity d 内 When the fresh air fan is not operating, it indicates that the user is not using the fresh air function to regulate indoor CO2 concentration. Therefore, after activating the humidification function, regulating indoor humidity takes priority over regulating indoor CO2 concentration. The control program prioritizes meeting the user's needs for regulating indoor humidity using fresh air, and detects the indoor humidity level. 内 Then, the current indoor CO2 concentration is detected, and the rate of change of CO2 concentration V is calculated. A .

[0032] In this embodiment, based on the concentration change rate V A and the first preset concentration change rate ΔV A预设1 The second preset concentration change rate ΔVA预设2 Methods for adjusting the speed of the fresh air fan based on the relationship between the two include: If V A >△V A预设1 If so, reduce the speed of the fresh air fan; If V A ≤△V A预设1 If so, increase the speed of the fresh air fan.

[0033] Specifically, when V A >△V A预设1 When V indicates that the indoor CO2 concentration has decreased to a preset acceptable range after the user turned on the fresh air system, the fresh air fan speed can be reduced by one level. A ≤△V A预设1 When the user turns on the fresh air system, the indoor CO2 concentration has already decreased, but it still needs to be reduced further to replenish more outdoor air with higher humidity.

[0034] In this embodiment, the method for reducing the speed of the fresh air fan includes: reducing the speed of the fresh air fan by one level.

[0035] In this embodiment, the method for increasing the rotational speed of the fresh air fan includes: If △V A预设2 ≤V A ≤△V A预设1 If so, the speed of the fresh air fan will be increased by one level; If V A <△V A预设2 If so, adjust the speed of the fresh air fan to the highest setting.

[0036] Specifically, when △V A预设2 ≤V A ≤△V A预设1 When V indicates that the indoor CO2 concentration has decreased somewhat after the user turned on the fresh air system, but further reduction is needed, the fresh air fan speed will increase by one level. A <△V A预设2 If the indoor CO2 concentration decreases slowly after the user turns on the fresh air system, the fresh air system will immediately operate at its highest fan speed to prioritize regulating the indoor CO2 concentration. In this case, the fresh air fan operates at its maximum speed, introducing the largest volume of fresh air, which will increase the indoor humidity.

[0037] In this embodiment, after increasing the speed of the fresh air fan by one level, the humidification method of the fresh air air conditioner further includes: Step S3: Obtain the indoor ambient humidity d 内 According to the indoor humidity d 内 and the first preset humidity △d 预设1 Second preset humidity △d 预设2The relationship between the two controls allows the fresh air fan to maintain its current speed or increase its speed.

[0038] Specifically, the indoor air humidity is assessed after the fresh air fan speed is reduced by one level, so that the fresh air fan speed can be maintained at the current speed or increased according to the indoor air humidity.

[0039] In this embodiment, based on the indoor ambient humidity d 内 and the first preset humidity △d 预设1 Second preset humidity △d 预设2 Methods for controlling the relationship between the fresh air fan and maintaining its current speed or increasing its speed include: If d 内 >△d 预设1 Then, the fresh air fan will be controlled to maintain its current speed. If △d 预设2 ≤d 内 ≤△d 预设1 If so, adjust the speed of the fresh air fan to the highest setting.

[0040] Specifically, when d 内 >△d 预设1 When △d is reached, it indicates that the indoor air humidity has reached the preset acceptable range, and the fresh air system continues to operate at the current fan speed; when △d 预设2 ≤d 内 ≤△d 预设1 If the indoor CO2 concentration needs to be further reduced and the indoor air humidity needs to be further increased, then the fresh air volume needs to be increased and the speed of the fresh air fan should be increased to the highest setting.

[0041] In this embodiment, after reducing the speed of the fresh air fan, the humidification method of the fresh air air conditioner further includes: Step S4: Obtain indoor ambient humidity d 内 According to the indoor humidity d 内 and the first preset humidity △d 预设1 Adjust the speed of the fresh air fan according to the relationship between them.

[0042] Specifically, the indoor air humidity is judged after the speed of the fresh air fan is reduced by one level, and the speed of the fresh air fan is adjusted according to the indoor air humidity to ensure that the indoor environment is always humid.

[0043] In this embodiment, in step S4, based on the indoor ambient humidity d 内 and the first preset humidity △d 预设1 Methods for adjusting the speed of the fresh air fan based on the relationship between the two include: If d 内 >△d 预设1 If so, reduce the speed of the fresh air fan; If d 内 ≤△d 预设1 If so, increase the speed of the fresh air fan.

[0044] Specifically, in d 内 >△d 预设1 If the indoor air humidity is within the preset acceptable range, then the fresh air deflector can be lowered to its lowest setting. (d) 内 ≤△d 预设1 If the CO2 concentration is acceptable, it means that the indoor air humidity still needs to be increased.

[0045] In this embodiment, in step S4, if △d 预设2 ≤d 内 ≤△d 预设1 If d 内 <△d 预设2 If so, adjust the speed of the fresh air fan to the highest setting.

[0046] Specifically, in △d 预设2 ≤d 内 ≤△d 预设1 At this time, the indoor air humidity needs to be further increased, so the speed of the fresh air fan should be increased by one level; in d 内 <△d 预设2 If the CO2 concentration is acceptable, it means that the indoor air is dry and the humidification speed needs to be increased. The fresh air fan should be raised to the highest setting to replenish more outdoor air with high humidity.

[0047] In this embodiment, based on the indoor ambient humidity d 内 and the first preset humidity △d 预设1 Second preset humidity △d 预设2 Methods for adjusting the speed of the fresh air fan based on the relationship between the two include: If d 内 >△d 预设1 Then, the fresh air fan will be controlled to run at the lowest setting; If △d 预设2 ≤d 内 ≤△d 预设1 Then, control the fresh air fan to run at the medium speed. If d 内 <△d 预设2 Then, the fresh air fan will be controlled to run at the highest speed.

[0048] Specifically, in d 内 >△d 预设1When the humidity level is within a certain range, it indicates that the indoor air humidity is already at its maximum acceptable level. There is no need to introduce more outdoor fresh air to regulate the humidity; the fresh air fan can operate at its lowest setting to introduce a small amount of fresh air to meet the user's humidification needs. At △d... 预设2 ≤d 内 ≤△d 预设1 If the humidity is low, it indicates a need for humidification. The fresh air fan should be set to medium speed to increase the volume of fresh air intake and accelerate the increase in indoor humidity. Then, assess the indoor CO2 concentration. 内 <△d 预设2 When the humidity is high, it indicates that the indoor air is dry and the demand for humidification is strong. The fresh air fan will run at its highest setting to introduce the maximum amount of outdoor fresh air to regulate indoor humidity and quickly increase indoor air humidity.

[0049] In this embodiment, after controlling the fresh air fan to operate at the lowest setting, the humidification method of the fresh air air conditioner further includes: Step S5: Obtain the rate of change V of indoor CO2 gas concentration. A Based on the concentration change rate V A and the first preset concentration change rate ΔV A预设1 The second preset concentration change rate ΔV A预设2 The relationship between the two controls allows the fresh air fan to maintain its current speed or increase its speed.

[0050] Specifically, the indoor CO2 concentration is assessed after the fresh air fan is running at its lowest setting, based on the concentration change rate V. A and the first preset concentration change rate ΔV A预设1 The second preset concentration change rate ΔV A预设2 The relationship between the two controls allows the fresh air fan to maintain its current speed or increase its speed, thereby improving the humidity level of the indoor air conditioning system.

[0051] In this embodiment, in step S5, based on the concentration change rate V A and the first preset concentration change rate ΔV A预设1 The second preset concentration change rate ΔV A预设2 Methods for controlling the relationship between the fresh air fan and maintaining its current speed or increasing its speed include: If V A >△V A预设1 Then, the fresh air fan will be controlled to maintain its current speed. If △V A预设2 ≤V A ≤△V A预设1 If so, the speed of the fresh air fan will be increased by one level; If V A <△V A预设2 If so, adjust the speed of the fresh air fan to the highest setting.

[0052] Specifically, in V A >△V A预设1 When the indoor CO2 concentration drops rapidly after the fresh air fan is turned on, meeting the maximum rate of change of indoor CO2 concentration, the fresh air fan can continue to operate at the current lowest fan speed; when △V A预设2 ≤V A ≤△V A预设1 When the temperature reaches a certain level, it indicates that the indoor CO2 concentration has decreased after the fresh air fan is turned on, but the rate of decrease is slightly slow. Since adjusting the indoor CO2 concentration has a lower priority than adjusting humidity, the fresh air fan speed is increased by one level to appropriately accelerate the decrease in indoor CO2 concentration. Increasing the fresh air fan speed by one level also increases the fresh air volume, which has a positive effect on regulating indoor humidity. At V... A <△V A预设2 If the air temperature is high, it means that after the fresh air fan is turned on, the indoor CO2 concentration decreases slowly. The fresh air fan speed increases to the highest setting to introduce the maximum fresh air volume to regulate and reduce the indoor CO2 concentration. The increased fresh air volume also has a positive effect on regulating indoor humidity.

[0053] In this embodiment, after controlling the fresh air fan to operate at the medium speed, the humidification method of the fresh air air conditioner further includes: Step S6: Obtain the rate of change V of indoor CO2 gas concentration. A Based on the concentration change rate V A and the first preset concentration change rate ΔV A预设1 The second preset concentration change rate ΔV A预设2 The relationship between the two controls allows the fresh air fan to maintain its current speed or increase its speed.

[0054] In this embodiment, in step S6, based on the concentration change rate V A and the first preset concentration change rate ΔV A预设1 The second preset concentration change rate ΔV A预设2 Methods for controlling the relationship between the fresh air fan and maintaining its current speed or increasing its speed include: If V A >△V A预设1 Then, the fresh air fan will be controlled to maintain its current speed. If △V A预设2 ≤V A ≤△V A预设1 If so, the speed of the fresh air fan will be increased by one level; If V A <△V A预设2 If so, adjust the speed of the fresh air fan to the highest setting.

[0055] Specifically, in V A >△VA预设1 When the indoor CO2 concentration drops rapidly after the fresh air fan is turned on, meeting the maximum rate of change of indoor CO2 concentration, the fresh air fan can continue to operate at the current fan speed; when ΔV A预设2 ≤V A ≤△V A预设1 When V indicates that the indoor CO2 concentration has decreased after the fresh air fan is turned on, the decrease is somewhat slow. Since adjusting the indoor CO2 concentration has a lower priority than adjusting humidity, the fresh air fan's fan speed should be increased by one level to appropriately accelerate the decrease in indoor CO2 concentration. Increasing the fan speed by one level also increases the fresh air volume, which has a positive effect on indoor humidity regulation. A <△V A预设2 When the fresh air fan is turned on, it indicates that the indoor CO2 concentration decreases slowly. The fresh air fan is raised to the highest setting and operates at the maximum fresh air volume to regulate and reduce the indoor CO2 concentration. The increased fresh air volume also has a positive effect on regulating indoor humidity.

[0056] This application also provides a fresh air conditioner (not shown) that uses the above-described fresh air conditioner humidification method.

[0057] As can be seen from the above description, the embodiments of the present invention achieve the following technical effects: When indoor humidification is required, first obtain the on / off status of the fresh air unit of the fresh air conditioner. If the fresh air unit is on, then obtain the rate of change V of indoor CO2 gas concentration. A Based on the concentration change rate V A and the first preset concentration change rate ΔV A预设1 The second preset concentration change rate ΔV A预设2 Adjust the speed of the fresh air fan according to the relationship between the two; if the fresh air system is not started, start the fresh air system and obtain the indoor ambient humidity d. 内 According to the indoor humidity d 内 and the first preset humidity △d 预设1 Second preset humidity △d 预设2 The relationship between the air conditioner and the indoor air conditioner is adjusted to change the speed of the fresh air fan. This allows the air conditioner to supplement indoor air humidity by introducing fresh outdoor air, thus achieving waterless humidification. This solves the problem of difficult maintenance and negative impact on user experience associated with air conditioners that have humidifiers installed, preventing users from experiencing dry air and improving user comfort.
