The air return opening 111 is located below the housing 110, and the air outlet opening 112 is located above the housing 110. Here, "up" and "down" are relative to the actual usage state of the air conditioner indoor unit 10. The "upper" and "lower" are relative terms, and the air return opening 111 is located below the air outlet opening 112. The air return opening 111 and the air outlet 112 can be arranged at any position on the front panel, the back panel or the side panel according to actual needs. In this embodiment, both the air return opening 111 and the air outlet 112 can be disposed on the front panel.
The air processing channel 115 may be an airflow channel extending from the air return opening 111 to the air outlet opening 112 from bottom to top. The wall surface of the housing 110 between the return air opening 111 and the outlet opening 112 defines an air treatment passage 115.
The airflow inducing device 120 is disposed in the air treatment channel 115, and is configured to induce the indoor ambient air to flow into the air treatment channel 115 from the air return opening 111 to form a treatment airflow, which is blown out from the air outlet 112 after being treated. That is, the airflow actuating device 120 may be used to create the supply airflow.

Here, "upstream" and "downstream" refer to relative positional relationships in the flow path of the process gas flow. The heat exchanger 150 is located downstream of the airflow actuation device 120, which means that the process airflow passes through the airflow actuation device 120 first and then through the heat exchanger 150. The type of the heat exchanger 150 may be selected according to the actual use requirement, and may be, for example, a tube-fin heat exchanger, a plate heat exchanger, or any other type of heat exchanger.

That is, the air treatment device 130 is disposed below the airflow actuating device 120. For example, the air treatment device 130 may be disposed below the support 160. The support member 160 may generally divide the air treatment duct 115 into upper and lower portions. The heat exchanger 150 may be disposed at an upper portion of the air handling passage 115 and the air handling device 130 may be disposed at a lower portion of the air handling passage 115. In operation of the airflow activation device 120, a process airflow flows through the air treatment device 130, the airflow activation device 120, and the heat exchanger 150 in that order.

The air treatment device 130 can be arranged in longitudinal abutment against a wall of the air treatment channel 115. The "longitudinal direction" is a direction substantially vertical to an actual use state of the air conditioner indoor unit 10. With this arrangement, the installation procedure of the air treatment device 130 can be simplified. The air treatment devices 130 may be in plurality and spaced apart along the perimeter wall of the air treatment channel 115. In some further embodiments, each air treatment device 130 may be used to treat a particular substance composition.
In other alternative embodiments, the air treatment device 130 may be disposed in the air treatment channel 115 at an angle along a predetermined inclination angle, and the shape of the air treatment device 130 may be adapted to the shape of the wall of the air treatment channel 115, so that almost all of the treatment air flows through the air treatment device 130, which is beneficial to improve the treatment efficiency of the treatment air flow by the air treatment device 130.
The main body 131 is made of MOF (Metal Organic Framework) material, and the main body 131 is configured to adsorb specific substance components in the process gas flow flowing through the surface and/or the inside thereof. The specific substance component may be one or more of moisture, carbon dioxide, formaldehyde, and the like.
For example, the MOF material may be ZIF-8, Zinc 2-Methylimidazole MOF, and the corresponding British name may be 2-Methylimidazole zincate, ZIF 8. CAS No.: 59061-53-9, formula: c8H10N4Zn, molecular weight: 227.600797176361. the composition of the MOF material may also be selected specifically for the actual air treatment needs, for example, depending on the type and physicochemical properties of the particular material composition to be treated. Since the composition and properties of various MOF materials are well known to those skilled in the art, they are not given here in any way.
The body 131 has a three-dimensional pore structure and a large specific surface area, and can adsorb a large amount of one or more of macromolecular components such as water vapor, carbon dioxide, and formaldehyde.
The main body part 131 made of the MOF material can adsorb various substance components, and by arranging the main body part 131 made of the MOF material in the air treatment device 130 and configuring the main body part 131 to adsorb specific substance components in the treatment airflow flowing through the surface and/or the interior of the main body part 131, the main body part 131 can be arranged to absorb moisture and/or other various harmful substance components in the indoor ambient air, which is beneficial to improving the air treatment capability of the air conditioner indoor unit 10, simplifying the structure of the air conditioner indoor unit 10 and saving the manufacturing cost.
The main body part 131 made of the MOF material has stable adsorption performance and long service life, and can reduce the replacement times of the air treatment device 130 in the use process of the air conditioner indoor unit 10, even without replacement, thereby prolonging the overall service life of the air conditioner indoor unit 10.
The present embodiment is illustrated with a specific substance component being water, and those skilled in the art should be fully capable of expanding on other specific substance components based on the understanding of the embodiment of the present embodiment.
In the prior art, the humidity parameter of some air conditioners is adjusted by regulating and controlling the temperature of a heat exchanger of an indoor unit. For example, when the indoor air needs to be cooled and dehumidified, the temperature of the heat exchanger of the indoor unit needs to be adjusted to be lower than the dew point temperature of the indoor air, so that the moisture in the heat exchange airflow is condensed on the surface of the heat exchanger in the process of exchanging heat with the heat exchanger of the indoor unit, and the cooling and dehumidifying functions can be realized.
However, the dew point temperature of the indoor air is often lower than the comfortable temperature of the human body, if the air conditioner is to be refrigerated and dehumidified, the air conditioner needs to be operated according to the target temperature lower than the comfortable temperature of the human body, the control logic is complex, the debugging process is difficult, the air outlet temperature of the indoor unit can be obviously lower than the comfortable temperature set by the user, the energy consumption of the air conditioner is increased, and the comfort level of the user is reduced.
In the present embodiment, the air treatment device 130 and the heat exchanger 150 are provided in the air treatment duct 115, the heat exchanger 150 and the air treatment device 130 are provided separately, the air treatment device 130 is used as a place for adsorbing a specific substance component, and the heat exchanger 150 is used as a place for exchanging heat, whereby the air treatment device 130 can be used as an adsorption place for specifically adsorbing the specific substance component. Since the MOF material can adsorb moisture, the air treatment device 130 and the heat exchanger 150 are used in cooperation, when the indoor unit 10 of the air conditioner operates in the cooling mode and the dehumidifying mode, the air treatment device 130 can adsorb moisture in the treated air flow to realize the dehumidifying function, and only the heat exchanger 150 is needed to adjust the temperature of the treated air flow. The temperature of the heat exchanger 150 does not need to be adjusted in the adjusting process to condense the moisture, so that the temperature of the heat exchanger 150 of the air conditioner indoor unit 10 can be prevented from being reduced for condensing the moisture in the refrigerating process, the energy consumption in the operation process of the air conditioner indoor unit 10 can be reduced, and the operation performance in the temperature and humidity double control process can be improved.
The air treatment device 130 is additionally arranged in the air conditioner indoor unit 10, the adsorption place and the heat exchange place are separately arranged, so that the heat exchanger 150 is only used for adjusting the temperature of the treated air flow, when the dehumidification function of the air conditioner indoor unit 10 is started, the air treatment device 130 can be adjusted and controlled, the operation parameters of a compression refrigeration system can be reduced or avoided, and the control logic of the air conditioner is simplified.
The air treatment device 130 is used as a place for adsorbing specific substance components, the dehumidification function can be realized under the condition that the temperature of the indoor unit heat exchanger 150 is not changed, the air outlet temperature can be prevented from being reduced in the dehumidification process, and the improvement of the comfort level of a human body when the indoor unit 10 of the air conditioner operates is facilitated.
The air treatment device 130 is disposed upstream of the airflow actuating device 120, and the heat exchanger 150 is disposed downstream of the airflow actuating device 120, so that when the airflow actuating device 120 operates, the treated airflow first flows through the air treatment device 130 to form a dry airflow, and then the dry airflow flows through the heat exchanger 150, and condensation water formed on the surface of the heat exchanger 150 can be reduced or avoided, so that the heat exchange efficiency of the heat exchanger 150 can be improved, and the energy saving and consumption reduction effects of the air conditioner indoor unit 10 can be improved to a certain extent.
The electrical heating portion 132 is disposed on the main body portion 131, and is configured to be controlled to be activated to heat the main body portion 131, so that the specific substance component adsorbed by the main body portion 131 is desorbed from the main body portion 131. The electrical heating portion 132 may be embedded in the body portion 131. For example, the electric heating part 132 may be an electric heating wire, and is wound and embedded in the body part 131. For another example, the body 131 may be provided with a cavity for mounting the electric heating unit 132, and the electric heating unit 132 may be an electric heating block and embedded in the cavity provided in the body 131.
The electrical heating portion 132 is disposed on the main body portion 131, and the main body portion 131 and the specific substance component can be desorbed after the electrical heating portion 132 is controlled to be activated, so that the main body portion 131 saturated in adsorption can rapidly recover the adsorption capacity, thereby realizing recycling. In the desorption process, the air treatment device 130 does not need to be taken out, and the main body 131 does not need to be regulated, which is beneficial to saving operation procedures and simplifying the control logic of the indoor unit 10 of the air conditioner.
When the air treatment device 130 is used to treat the treatment air flow, only the on-off state of the electric heating part 132 needs to be adjusted, and the control logic is relatively simple. Compared with the mode of adjusting the humidity of the processing air flow by adjusting and controlling the temperature of the heat exchanger 150, the embodiment reduces the energy consumption of the compression refrigeration system, and only increases the energy consumption of the electric heating part 132, and the energy consumption of the electric heating part 132 is relatively low, so that the scheme of the embodiment can achieve an obvious energy-saving effect.
The electrical heating portion 132 may be a plurality, and one or more of the plurality of electrical heating portions 132 is configured to be controllably activated to adjust the rate at which a particular substance component is desorbed from the body portion 131.
The number of the electric heating portions 132 may be set according to the maximum adsorption capacity of the body portion 131, so that all of the specific substance components adsorbed by the body portion 131 are desorbed after the plurality of electric heating portions 132 are simultaneously operated for a set period of time. The maximum adsorption capacity is an amount of the specific material component adsorbed when the main body 131 is saturated.
By selectively activating one or more of the plurality of electrical heating portions 132, the heating efficiency of the electrical heating portions 132 may be adjusted, thereby adjusting the rate at which a particular substance component is desorbed from the body portion 131.
When the main body 131 is saturated in adsorption, the specific substance component in the process air flow is hardly adsorbed. In the air conditioner indoor unit 10 of the present embodiment, when the main body 131 is adsorbed to reach the saturation state or close to the saturation state, the electric heating unit 132 may be activated to heat the main body 131. In some further embodiments, the air conditioner indoor unit 10 may further include a component content sensor for detecting the content of a specific substance component in the process air flow. The constituent content sensor may be a plurality of sensors disposed within the air handling passage 115, including a first sensor and a second sensor. The first sensor is disposed upstream of the air treatment device 130 for detecting the content of a particular characteristic component of the treatment air flow prior to flowing through the air treatment device 130. And a second sensor is disposed downstream of the air treatment device 130 for detecting the content of the particular material component of the treated air stream after exiting the air treatment device 130.
If the difference between the detection value of the first sensor and the detection value of the second sensor is smaller than the set threshold, it indicates that the main body 131 hardly adsorbs the specific substance component, and the electric heating unit 132 needs to be activated to heat the main body 131. That is, the electric heating portion 132 may be configured to be controlled to be activated in a case where a difference between the detection value of the first sensor and the detection value of the second sensor is smaller than a set threshold value.
The desorption process of the specific material component may also increase the humidity of the indoor ambient air when the specific material component is moisture. The humidification rate of the air treatment device 130 can be adjusted by regulating the number of activations of the electric heating part 132.
In other alternative embodiments, electrically heated portion 132 may also be used to increase the temperature of the process gas stream. For example, in winter conditions, if the temperature of the indoor ambient air is low, the temperature of the processing air flow can be increased when the electric heating part 132 is activated to heat the main body part 131, so as to improve the comfort of the humidification process.
Take specific material components as water as an example. For example, after the air conditioner indoor unit 10 receives the start signal of the cooling mode and/or the dehumidifying mode, the electric heating portion 132 is turned off or kept turned off, the airflow actuating device 120 is turned on, and causes the indoor ambient air to flow into the air processing passage 115 from the air return opening 111 to form the processing airflow, the processing airflow firstly flows through the air processing device 130 (the main body portion 131 adsorbs specific substance components in the processing airflow), then flows through the heat exchanger 150 (when the compression refrigeration system is operated, the heat exchanger 150 can exchange heat with the processing airflow), and finally is blown to the indoor environment from the air outlet 112.
Take specific material components as water as an example. For another example, after the air conditioner indoor unit 10 receives the signal for starting the humidification mode, the electric heating part 132 is turned on, the airflow actuator 120 is turned on, and causes the indoor environment air to flow into the air processing channel 115 from the air return opening 111 to form the processing airflow, and the processing airflow firstly flows through the air processing device 130 (the specific substance component adsorbed by the main body part 131 is desorbed from the main body part 131 and leaves the air processing device 130 along with the processing airflow), and then is blown to the indoor environment from the air outlet 112.
In still other alternative embodiments, the specific material composition may include harmful material compositions such as carbon dioxide and formaldehyde. The air conditioner indoor unit 10 may be connected to a smart window in advance. The air conditioner indoor unit 10 may start the electric heating part 132 to heat the main body part 131 when the smart window is in the window-opened state and when it is detected that the target user is not present in the indoor environment, so as to desorb the harmful specific substance component adsorbed by the main body part 131. In some further embodiments, if the smart window is in the window closing state, the indoor unit 10 of the air conditioner may further send a window opening request message to the smart window, so that the smart window executes the window opening instruction.
For example, a desorption mode for heating the main body 131 to realize desorption may be preset in the operation mode of the air conditioner indoor unit 10. After the indoor unit 10 of the air conditioner receives the activation signal of the desorption mode, when the smart window is in the open state and the target user is not present in the indoor environment, the electric heating part 132 is turned on, the airflow actuating device 120 is activated, and the indoor environment air is caused to flow into the air processing passage 115 from the air return opening 111 to form a processing airflow, the processing airflow first flows through the air processing device 130 (the specific substance component adsorbed by the main body part 131 is desorbed from the main body part 131 and leaves the air processing device 130 along with the processing airflow), and then is blown into the indoor environment from the air outlet 112, and the specific substance component blown into the indoor environment can be discharged to the outdoor environment from the window.
The air handling device 130 of the air conditioner indoor unit 10 of the present embodiment includes a main body 131 made of MOF material. Since the MOF material is an excellent adsorbing material capable of adsorbing a plurality of substance components, by disposing the main body 131 made of the MOF material in the air treatment device 130 and configuring the main body 131 to adsorb specific substance components in the treatment air flowing through the surface and/or the interior of the main body 131, a plurality of harmful substance components in the indoor ambient air can be adsorbed only by disposing the main body 131, which is not only beneficial to improving the air treatment capability of the air conditioner indoor 10, but also can simplify the structure of the air conditioner indoor 10 and save the manufacturing cost.
The main body part 131 made of the MOF material can adsorb moisture, and when the air conditioner indoor unit 10 operates in the refrigeration and dehumidification mode, the main body part 131 can be used for adsorbing moisture in the air flow, so that the temperature of the heat exchanger 150 of the air conditioner indoor unit 10 can be prevented from being reduced for condensing the moisture in the refrigeration process, the energy consumption of the air conditioner indoor unit 10 in the operation process can be reduced, the control logic of the air conditioner indoor unit 10 can be simplified, and the comfort level of a human body during the operation of the air conditioner indoor unit 10 can be improved.
Thus, it should be appreciated by those skilled in the art that while a number of exemplary embodiments of the invention have been illustrated and described in detail herein, many other variations or modifications consistent with the principles of the invention may be directly determined or derived from the disclosure of the present invention without departing from the spirit and scope of the invention. Accordingly, the scope of the invention should be understood and interpreted to cover all such other variations or modifications.
