The specific meanings of the above terms in the present invention can be understood in specific cases to those skilled in the art.
The air conditioner is used as a device for adjusting indoor temperature, and is widely applied to numerous occasions such as hotels, office buildings, hospitals or markets. The air conditioner can be a central air conditioner, an air duct machine, a vertical air conditioner and the like.
The air conditioner according to the embodiment of the application can comprise an air conditioner indoor unit and an air conditioner outdoor unit.
Specifically, the air conditioning indoor unit may include an indoor heat exchanger.
Specifically, the outdoor unit of the air conditioner may include a compressor, a throttling device (e.g., an electronic expansion valve), and an outdoor heat exchanger.
The outdoor heat exchanger, the compressor, the indoor heat exchanger and the throttling device are communicated through refrigerant pipelines to form a refrigerant loop. The air conditioner may include a cooling mode, a heating mode, a blowing mode, and a dehumidifying mode.
When the air conditioner is in a cooling mode, the outdoor heat exchanger serves as a condenser, and the indoor heat exchanger serves as an evaporator. The refrigerant discharged by the compressor is a high-temperature high-pressure gaseous refrigerant, the high-temperature high-pressure gaseous refrigerant flows to the condenser and exchanges heat with the surrounding environment in the outdoor heat exchanger, the temperature of the refrigerant is reduced, the refrigerant flows through the throttling device to be throttled and reduced to form a low-temperature low-pressure liquid refrigerant, the refrigerant flows to the evaporator, the refrigerant exchanges heat with indoor air in the evaporator to reduce the temperature of the indoor environment, and the refrigerant after heat exchange flows into the compressor to complete refrigerant circulation.
When the air conditioner is in a heating mode, the outdoor heat exchanger is used as an evaporator, and the indoor heat exchanger is used as a condenser. The high-temperature and high-pressure gaseous refrigerant discharged from the compressor flows to the condenser, and exchanges heat with the indoor environment in the condenser to improve the temperature of the indoor environment. And then, the refrigerant flows through the throttling device, forms a low-temperature and low-pressure liquid refrigerant after throttling and pressure reduction, flows to the evaporator, exchanges heat with the outdoor environment in the evaporator, and flows into the compressor after heat exchange to complete refrigerant circulation.
When the air conditioner is in an air supply mode, the compressor does not work, the fan works to convey natural air to the air outlet from the air outlet of the indoor unit of the air conditioner, and the mode is low in power and energy consumption.
When the air conditioner is in a dehumidification mode, the outdoor heat exchanger is used as a condenser, the indoor heat exchanger is used as an evaporator, the compressor runs intermittently, when air in a room is sucked by a fan of an indoor unit of the air conditioner and passes through the indoor heat exchanger, water in the air is condensed into water when meeting the condensation, then the water is converged into a drain pipe and is led to the outside to be discharged, and the water in the air in the room is removed. While in dehumidification mode there is a concomitant drop in room temperature.
Referring to fig. 1, fig. 1 is a schematic diagram of an air conditioning indoor unit 100 in the prior art. The indoor air conditioner 100 includes a casing 110, a fan 102, and an indoor heat exchanger 103. The housing 110 defines an air duct 101 therein, and the housing 110 is provided with an air inlet and an air outlet 104 communicated with the air duct 101. The fan 102 and the indoor heat exchanger 103 are disposed in the air duct 101, the fan 102 is configured to drive air to flow from the air inlet to the air outlet 104, and the air entering through the air inlet can flow to the air outlet 104 after heat exchange by the indoor heat exchanger 103, and then flows out through the air outlet 104.
The indoor unit 100 of the air conditioner can be matched with an outdoor unit of the air conditioner to realize refrigeration, heating, dehumidification and air supply. However, the air conditioning indoor unit 100 has only one air duct 101, and can only achieve the single operation (cooling, heating, dehumidifying, and blowing) function requirements in the same space. If different users in the same space experience different temperatures, for example, when the air conditioner is turned on in the same meeting room in summer, some people feel cold, and some people feel hot, at this time, the air conditioner indoor unit 100 cannot realize the regional temperature control, the regional air supply, the wind speed adjustment, and the like. That is, the air conditioning indoor unit 100 cannot meet different needs of users in different areas in the same space.
In order to solve the above technical problems, the present invention provides an indoor unit 100 of an air conditioner having dual ducts and dual dampers. The air conditioning indoor unit 100 may be used for a duct unit, a central air conditioner, a floor air conditioner, and the like. In the following embodiments, the air conditioning indoor unit 100 is used in a ducted air conditioner as an example, but this is not to be construed as limiting the present invention.
Referring to fig. 2 to 4, fig. 2 isbase:Sub>A perspective view of an air conditioning indoor unit 100 according to an embodiment of the present invention, fig. 3 isbase:Sub>A cross-sectional view taken alongbase:Sub>A-base:Sub>A line in fig. 2, and fig. 4 isbase:Sub>A cross-sectional view taken alongbase:Sub>A-B line in fig. 2, in whichbase:Sub>A first damper 141 is in an open state.
The indoor air conditioner 100 includes a cabinet 110, a first indoor heat exchanger 131, a second indoor heat exchanger 132, a first fan 121, and a second fan 122.
Referring to fig. 2, the housing 110 is in a rectangular shape. For convenience of the following description of the embodiments, an XYZ coordinate system is established. Specifically, the width direction of the housing 110 is defined as the X-axis direction, the length direction of the housing 110 is defined as the Y-axis direction, and the height direction of the housing 110 is defined as the Z-axis direction. It is understood that the coordinate system of the housing 110 can be flexibly configured according to practical requirements, and is not particularly limited herein.
The cabinet 110 defines therein a first air path 111 and a second air path 112 spaced apart from each other. The housing 110 is provided with a first air inlet 1111 and a first air outlet 1112 which are communicated with the first air duct 111, and the housing 110 is provided with a second air inlet 1121 and a second air outlet 1122 which are communicated with the second air duct 112. Specifically, referring to fig. 3, a partition plate 150 is disposed in the casing 110, and the casing 110 separates the first air duct 111 and the second air duct 112 by the partition plate 150. The first air duct 111 and the second air duct 112 may be arranged in a width direction (i.e., an X-axis direction in fig. 2) of the cabinet 110. In this way, the height of the indoor unit 100 can be reduced, and the indoor unit 100 can be conveniently installed in a ceiling of a room.
It is understood that, in other embodiments, when the air conditioning indoor unit 100 is used in a floor air conditioner, the first air duct 111 and the second air duct 112 may be arranged in the height direction of the cabinet 110.
Referring to fig. 4, the first air duct 111 includes a first heat exchanging channel 1113 and a first through channel 1114, and the first heat exchanging channel 1113 and the first through channel 1114 are connected in parallel between the first air inlet 1111 and the first air outlet 1112. Wherein the first indoor heat exchanger 131 is provided in the first heat exchange passage 1113.
The first fan 121 is disposed in the first air duct 111, and the first fan 121 is configured to drive air to flow from the first air inlet 1111 to the first air outlet 1112. The first fan 121 may be a centrifugal fan, a cross flow fan, or the like.
Specifically, referring to fig. 3 and 4, in the process of the air flow flowing from the first air inlet 1111 to the first air outlet 1112, a part of the air flow may flow through the first heat exchanging channel 1113 to flow to the first air outlet 1112, and another part of the air flow may flow through the first straight channel 1114 to directly flow to the first air outlet 1112.
Because the first indoor heat exchanger 131 is arranged in the first heat exchange channel 1113, the airflow entering the first heat exchange channel 1113 can flow to the first air outlet 1112 after exchanging heat and changing the temperature through the first indoor heat exchanger 131, and the airflow entering the first straight channel 1114 directly flows to the first air outlet 1112 without exchanging heat through the first indoor heat exchanger 131. Therefore, the air flow after heat exchange flowing out of the first heat exchange channel 1113 and the air flow which directly flows out of the first straight channel 1114 and is not subjected to heat exchange can be mixed at the first air outlet 1112 to form mixed air, and the mixed air is blown out from the first air outlet 1112, so that the softness of the air flow flowing out of the first air outlet 1112 can be improved, and the comfort degree of a user is improved.
For example, in the first indoor heat exchanger 131, the temperature of the heat-exchanged air flow flowing out of the first heat exchange passage 1113 is low in the cooling mode, and if the air flow is directly blown to the user, the user may feel discomfort. And the air current that flows out from first through channel 1114 does not pass through the heat transfer of first indoor heat exchanger 131, consequently, the air current temperature that directly flows out from first through channel 1114 is higher than the temperature of the air current that flows out from first heat transfer passageway 1113, and above-mentioned two air currents mix the heat transfer in first air outlet 1112 department, can alleviate the air-out temperature of first air outlet 1112, and then improve user's comfort level.
Further, referring to fig. 4, a first damper 141 is further disposed in the first air duct 111, and the first damper 141 is used for adjusting the opening degree of the first straight passage 1114. Specifically, a first driving motor (not shown) may be disposed in the first air path 111, and the opening degree of the first damper 141 and thus the opening degree of the first through path 1114 may be adjusted by the first driving motor. It should be noted that, the larger the opening of the first through passage 1114 is, the larger the flow area in the first air duct 111 is, the smaller the flow velocity of the air flow is, and the shorter the air supply distance is; the smaller the opening of the first through passage 1114, the smaller the flow area in the first air passage 111, the larger the flow velocity of the air flow, and the longer the air blowing distance. Thus, the flow rate of the air flow flowing out of the first through passage 1114 can be adjusted by adjusting the opening degree of the first through passage 1114, and the flow rate and the air supply distance of the air flow at the first air outlet 1112 can be adjusted.
Therefore, when the first through channel 1114 is opened, the airflow rate at the air outlet can be reduced, thereby improving the comfort of the user.
Referring to fig. 3, the second air duct 112 includes a second heat exchange channel and a second through channel, and the second heat exchange channel and the second through channel are connected in parallel between the second air inlet 1121 and the second air outlet 1122; a second indoor heat exchanger 132 is disposed in the second heat exchanging channel, and a second air door (not shown) is disposed in the second air duct 112, and the second air door is used for adjusting the opening degree of the second through channel. Specifically, a second driving motor (not shown) may be disposed in the second air duct 112, and the opening degree of the second damper is adjusted by the second driving motor, so as to adjust the opening degree of the second through passage.
The second fan 122 is disposed in the second air duct 112, and the second fan 122 is used for driving air to flow from the second air inlet 1121 to the second air outlet 1122. The second fan 122 may be a centrifugal fan, a crossflow fan, or the like. The type of the first fan 121 and the type of the second fan 122 may be the same or different.
Like this, through setting up mutually independent first wind channel 111 and second wind channel 112 to set up first air door 141 in first wind channel 111, set up the second air door in second wind channel 112, can control the air-out condition in first wind channel 111 and second wind channel 112 respectively, realize carrying out the subregion control to different regions in the same space, can provide multiple air-out mode simultaneously, in order to satisfy different users' demand.
For example, in the operation modes of the indoor air conditioner 100, such as the cooling mode, the heating mode, the dehumidification mode, and the air supply mode, the first through channel 1114 in the first air duct 111 may be closed, that is, the first damper 141 is in a closed state, and the opening degree of the second through channel in the second air duct 112 is set to be the maximum, that is, the second damper is in a fully open state, so that the air speed of the area corresponding to the first air outlet 1112 is relatively large, the air supply distance is relatively long, the air speed of the area corresponding to the second air outlet 1122 is relatively small, the air supply distance is relatively short, and different requirements of users in different areas can be further satisfied.
In other embodiments, the air outlet can be controlled in different regions by setting the opening degrees of the first damper 141 and the second damper to be unequal under the condition that the first damper 141 and the second damper are both opened.
For another example, in a cooling or heating mode, the first through passage 1114 and the second through passage may be both closed, that is, the first air door 141 and the second air door are both closed, so that all the air flow in the first air duct 111 flows out through the first air outlet 1112 after heat exchange by the first indoor heat exchanger 131, and all the air flow in the second air duct 112 flows out through the second air outlet 1122 after heat exchange by the second indoor heat exchanger 132, so as to ensure that all the air flow flows out after heat exchange, thereby improving cooling or heating efficiency, and achieving rapid cooling or heating.
For another example, in the cooling mode, the heating mode, the dehumidification mode, the air supply mode, and the like, only the first air duct 111 or the second air duct 112 may be controlled to discharge air, so as to reduce the energy consumption of the indoor unit 100 of the air conditioner, and further reduce the energy consumption of the air conditioner.
In some embodiments, the first fan 121 may be disposed upstream or downstream of the first indoor heat exchanger 131 in the direction of the flow of the air stream. For example, in the example of fig. 3, the first fan 121 is located upstream of the first indoor heat exchanger 131. Specifically, the first fan 121 is located between the first indoor heat exchanger 131 and the first air inlet 1111, and the first fan 121 is configured to deliver the airflow at the first air inlet 1111 to the first heat exchange passage 1113 and the first through passage 1114.
In other embodiments, the first fan 121 is located downstream of the first indoor heat exchanger 131. Specifically, the first fan 121 is located between the first indoor heat exchanger 131 and the first air outlet 1112, and the first fan 121 is configured to convey the airflow flowing out of the first heat exchange channel 1113 and the first straight channel 1114 to the first air outlet 1112.
Further, the output power of the first fan 121 can be adjusted, so as to adjust the air volume and the flow rate flowing through the first fan 121.
Similarly, the second fan 122 may be disposed upstream or downstream of the second indoor heat exchanger 132 in the airflow flowing direction, and the output power of the second fan 122 may be adjusted by a gear, so as to adjust the air volume and the flow rate flowing through the second fan 122.
In some embodiments, at least one end of the first indoor heat exchanger 131 is spaced apart from an inner wall of the first air duct 111, and a first through passage 1114 is defined between the first indoor heat exchanger 131 and the inner wall of the first air duct 111. For example, in the example of fig. 3, the upper end of the first indoor heat exchanger 131 is disposed spaced apart from the inner wall of the first duct 111. It is understood that, in other embodiments, the lower end, the left end and the right end of the first indoor heat exchanger 131 may be spaced apart from the inner wall of the first air duct 111. Or the upper end and the lower end of the first indoor heat exchanger 131 are both spaced apart from the inner wall of the first air duct 111. Therefore, the first air duct 111 can be divided into the first through passage 1114 and the first heat exchange passage 1113 by the first indoor heat exchanger 131, and the structure is simple and the assembly is convenient.
Specifically, the airflow flowing through the first air duct 111 is divided into the airflow flowing through the first indoor heat exchanger 131 and the airflow not flowing through the first indoor heat exchanger 131, the airflow flowing through the first through duct 1114 and the airflow flowing through the first heat exchange channel 1113 mix at the downstream of the first indoor heat exchanger 131, and then flow out from the first air outlet 1112, so that the comfort level of the user in the area corresponding to the first air outlet 1112 is improved.
In some embodiments, referring to fig. 4 and 5, fig. 5 is another schematic view of the air conditioning indoor unit shown in fig. 4, wherein the first damper is in a closed state. The first damper 141 is disposed between the first indoor heat exchanger 131 and the inner wall of the first air duct 111, and in a state where the first damper 141 blocks the first through passage 1114, an end of the first damper 141 close to the first indoor heat exchanger 131 is a first end, an end of the first damper 141 away from the first indoor heat exchanger 131 is a second end, and the first end can rotate toward the first air outlet 1112 relative to the second end. In this way, the first end of the first damper 141 is rotated relative to the second end of the first damper 141, thereby adjusting the opening of the first through passage 1114. Moreover, when the first damper 141 is in a state of opening the first through passage 1114, the first end rotates towards the first air outlet 1112 relative to the second end, and the first damper 141 can guide the airflow flowing out of the first through passage 1114, so that the airflow flowing out of the first through passage 1114 and the airflow flowing out of the first heat exchange passage 1113 are fully mixed.
Referring to fig. 5, when the first damper 141 blocks the first straight passage 1114, the flow area of the first air duct 111 is the smallest, and the airflow can only flow out through the first indoor heat exchanger 131, so that the wind resistance of the first air duct 111 is the largest, and the airflow velocity of the first air outlet 1112 is the largest. Referring to fig. 4, when the first end of the first damper 141 rotates towards the first air outlet 1112 relative to the second end, and the opening of the first straight passage 1114 reaches a maximum degree, the flow area of the first air channel 111 is the maximum, so that the wind resistance of the first air channel 111 is the minimum, and the airflow speed of the first air outlet 1112 is the softest.
Referring to fig. 4 and 5, the first indoor heat exchanger 131 may be obliquely disposed in the first air duct 111, and the first indoor heat exchanger 131 is obliquely disposed, so that on one hand, a contact area between the airflow in the first air duct 111 and the first indoor heat exchanger 131 may be increased, and a heat exchange area may be increased. On the other hand, the first indoor heat exchanger 131 having a relatively large volume may be disposed in a limited space, thereby reducing the volume of the first duct 111. The second indoor heat exchanger 132 may also be obliquely disposed within the second air duct 112.
It is understood that, in other embodiments, the first indoor heat exchanger 131 may also be vertically disposed in the first air duct 111.
In some embodiments, the second heat exchange channel and the second pass-through channel may be separated by a second indoor heat exchanger 132. The setting position and setting mode of the second indoor heat exchanger 132 in the second air duct 112 are the same as those of the first indoor heat exchanger 131 in the first air duct 111, and the setting position and setting mode of the second damper are the same as those of the first damper 141, which is not described again here.
In other embodiments, referring to fig. 6, fig. 6 is a schematic view of the first air duct 111 in other embodiments of the invention. The first indoor heat exchanger 131 may include a first heat exchange section 1311 and a second heat exchange section 1312, the first heat exchange section 1311 and the second heat exchange section 1312 are spaced apart from each other, and a first through channel 1114 is defined between the first heat exchange section 1311 and the second heat exchange section 1312, so that an airflow passing through the first heat exchange section 1311 exchanges heat through the first heat exchange section 1311, an airflow passing through the second heat exchange section 1312 exchanges heat through the second heat exchange section 1312, and an airflow passing through the first through channel 1114 between the first heat exchange section 1311 and the second heat exchange section 1312 directly flows to the first air outlet 1112 without exchanging heat through the first indoor heat exchanger 131. In this way, the first heat exchange passage 1113 and the first through passage 1114 may be also separated in the first air passage 111 by the first indoor heat exchanger 131.
In some embodiments, the indoor unit 100 may further include a control module for controlling the first and second fans 121 and 122 to be turned on or off and for adjusting the opening degrees of the first and second dampers 141 and 122. In this way, the air outlet mode of the indoor unit 100 of the air conditioner can be controlled by the control module.
Specifically, the air outlet modes of the indoor unit 100 may include one or more of a first air outlet mode, a second air outlet mode, a third air outlet mode, a fourth air outlet mode, and a fifth air outlet mode.
For example, in the first air outlet mode, the control module may control the first fan 121 and the second fan 122 to be both opened, and control the first damper 141 and the second damper to be both closed. In the second air outlet mode, the control module may control the first fan 121 to be opened, the first damper 141 to be closed, and the second fan 122 to be closed. In the third air outlet mode, the control module may control the first fan 121 to be opened, the first damper 141 to be opened, and the second fan 122 to be closed. In the fourth air outlet mode, the control module may control the first fan 121, the second fan 122, the first damper 141, and the second damper to be opened, and the opening degree of the first damper 141 is equal to the opening degree of the second damper. In the fourth air outlet mode, the control module may control the first fan 121 to be opened, the second fan 122 to be opened, and the opening degree of the first damper 141 and the opening degree of the second damper to be unequal.
Referring to fig. 7, the electrical control schematic diagram of the present invention is designed with two driving circuits 62003 with independent control, which are controlled by pins P1 to P4 and P5 to P8 of the main control MCU to output control signals, so as to independently control the stepping motors of the first damper 141 and the second damper. Meanwhile, the system is also provided with other UART circuits for direct current motor communication, indoor and outdoor communication circuits, indoor wire control communication circuits and other common control circuits for multi-split air conditioners, such as electronic expansion valves, water pumps, temperature sensor detection and the like.
The specific implementation process is as follows: two independently controllable dampers (i.e. a first damper 141 and a second damper) are configured inside the indoor unit 100 of the air conditioner, each damper is independently controlled by a stepping motor, and the opening and closing angle can be controlled at will according to a control signal. Meanwhile, the two air doors divide the air duct in the indoor air-conditioning unit 100 into two parts, and under the condition of a certain set rotating speed of the first driving motor and the second driving motor, the opening and closing angle of each air door is independently controlled respectively, the air mixing degree of air which does not flow through the indoor heat exchanger and air which flows through the indoor heat exchanger in each air duct is controlled, the air temperature and the air flow rate of each air duct are controlled, and finally the indoor air supply control in the same space of the indoor air-conditioning unit 100 is realized.
In some embodiments, the control module is further configured to obtain an indoor temperature T1 and a set temperature T2 of the indoor unit 100 of the air conditioner, and compare the difference between the indoor temperature and a temperature set by a user, so as to automatically control an air outlet mode of the indoor unit 100 of the air conditioner, thereby improving intelligent and automatic control of the indoor unit 100 of the air conditioner.
In some embodiments, the air conditioning indoor unit 100 includes a temperature sensor for detecting an indoor temperature, and the control module is electrically connected to the temperature sensor to obtain the indoor temperature detected by the temperature sensor.

Therefore, the air flow in the first air duct 111 can be ensured to flow out after being subjected to heat exchange through the first indoor heat exchanger 131, the air flow in the second air duct 112 can be ensured to flow out after being subjected to heat exchange through the second indoor heat exchanger 132, the heat exchange efficiency is high, and the refrigerating or heating efficiency can be further improved.

Therefore, the first fan 121 works, and the second fan 122 does not operate, so that energy consumption can be reduced, and an energy-saving effect is achieved. Further, the first damper 141 is opened, so that the speed of the air flow discharged from the first air duct 111 can be reduced, the cooling and heating effects can be alleviated, and the comfort of the user can be improved.
Another embodiment of the present invention further provides a method for controlling an air-conditioning indoor unit 100: the method comprises the following steps: acquiring an air outlet mode of the indoor unit 100 of the air conditioner; the air outlet modes of the indoor unit 100 of the air conditioner may include one or more of a first air outlet mode, a second air outlet mode, a third air outlet mode, a fourth air outlet mode, and a fifth air outlet mode.
