Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of air conditioning, and particularly provides a flow-guiding mixed air conditioning system and a flow-guiding mixed air conditioning method. BACKGROUND

[0002] With the increasing popularity of air conditioners in rooms, even as a standard configuration of the room, people have higher and higher requirements for room air conditioners, not only requiring fast cooling and heating speed of the air conditioner, but also requiring less energy consumption. One method of fast cooling or heating is to increase the air volume of the air conditioner, and another method is to increase the difference between the air outlet temperature of the air conditioner and the indoor set temperature. However, the increase of the air volume will inevitably lead to the increase of the power of the air conditioner fan, which cannot meet the requirement of energy saving and consumption reduction. Increasing the difference between the air outlet temperature and the set temperature will also lead to the increase of the power of the compressor and the increase of energy consumption.

[0003] Some existing air conditioners improve the air volume under the same power by optimizing the structure of the fan to improve the air outlet efficiency of the fan. However, these improvements to the structure of the fan itself do not significantly improve the air volume, and cannot solve the problem of direct blowing of air outlet to the human body. Therefore, there is a need for a new technology to solve such problems in the field. SUMMARY

[0004] The present application aims to solve the above technical problems, that is, to solve the problem that the existing air conditioner cannot balance fast temperature adjustment and energy saving and user comfort.

[0005] In a first aspect, the present application provides a flow-guiding mixed air conditioning system, which comprises a base, an air conditioner main machine and a functional machine, the air conditioner main machine and the functional machine are arranged side by side on the base with a distance between them and have the same air outlet direction; the air conditioner main machine is provided with a complete evaporation and condensation system to deliver cold air or hot air to the indoor as needed, and the functional machine is provided with an air flow circulation system; the functional machine is arranged to be movable relative to the air conditioner main machine on the base.

[0006] Further, the air conditioning system is a cabinet machine system, the base is the base of the cabinet machine system, the base is provided with a sliding rail, and the functional machine is slidably arranged on the base along the sliding rail.

[0007] Further, the air flow circulation system is a fresh air system, the functional machine comprises an air guiding port close to its air outlet, and the air guiding port is provided with a movable adjusting plate to adjust the opening degree of the air guiding port.

[0008] Further, the air conditioning system further comprises a first temperature sensor, a second temperature sensor and a controller, the first temperature sensor is arranged at the air outlet of the air conditioning host, the second temperature sensor is arranged at the air outlet of the functional machine, and the controller can control the functional machine to move on the base according to the detection value of the first temperature sensor and / or can control the adjustment plate to move to adjust the opening degree of the air inlet according to the detection value of the second temperature sensor.

[0009] In the second aspect, the application further discloses an air flow guiding and mixing method of the air conditioning system, the air flow guiding and mixing method comprises the following steps: detecting the air outlet temperature of the air conditioning host; determining a first difference between the air outlet temperature of the air conditioning host and a predetermined indoor temperature; and controlling the position of the functional machine relative to the air conditioning host on the base according to the first difference.

[0010] Further, the step of "controlling the position of the functional machine relative to the air conditioning host on the base according to the first difference" specifically comprises: if the first difference is greater than a first set threshold, controlling the functional machine to move to a position where the air outlet is flush with the air outlet of the air conditioning host; and / or if the first difference is less than the first set threshold, controlling the functional machine to move to a position behind the air conditioning host.

[0011] Further, when the first difference is less than the first set threshold, the distance by which the functional machine moves backward relative to the air conditioning host is inversely proportional to the size of the first difference.

[0012] Further, the air flow circulation system is a fresh air system, the functional machine comprises an air inlet close to the air outlet thereof, and the air flow guiding and mixing method further comprises the following steps: detecting the air outlet temperature of the functional machine; determining a second difference between the air outlet temperature of the functional machine and an outdoor temperature; and controlling the opening degree of the air inlet according to the second difference.

[0013] Further, the step of "controlling the opening degree of the air inlet according to the second difference" specifically comprises: if the second difference is greater than a second set threshold, adjusting the opening degree of the air inlet to the maximum; and / or if the second difference is less than the second set threshold, adjusting the opening degree of the air inlet to be less than the maximum.

[0014] Further, when the second difference is less than the second set threshold, the opening degree of the air inlet is proportional to the size of the second difference.

[0015] In the case of adopting the above technical solutions, the air conditioning system of the present application blows the main airflow from the air outlet of the air conditioning host and blows the auxiliary airflow from the air outlet of the functional machine when the air conditioning system is in the refrigeration or heating operation. Since the flow rates of the main airflow and the auxiliary airflow are large, according to Bernoulli's theorem, a negative pressure zone is formed between the main airflow and the auxiliary airflow, and one end of the flow guide channel is located in the negative pressure zone, so that a pressure difference is formed between the two ends of the flow guide channel. The airflow flows from the end with higher air pressure to the end with lower air pressure, and is mixed with the main airflow and the auxiliary airflow, so that the overall air volume is doubled. Therefore, the cold air or hot air can be diffused faster in the room, and the refrigeration or heating efficiency can be improved. At the same time, for the power consumption of the air conditioning system, this way of improving the airflow does not need to increase the power of a single fan. Compared with the traditional way of improving the power of the fan, the air conditioning system of the present application is more energy-saving, can greatly increase the air volume without increasing the energy consumption, and improves the air conditioning efficiency. In addition, by being mixed with the auxiliary airflow, the temperature of the main airflow is neutralized (reduced in heating and increased in refrigeration), avoiding the discomfort caused by directly blowing to the human body. Furthermore, by adjusting the position of the functional machine, the size of the airflow in the flow guide channel can also be controlled, so that the air volume and the air mixing degree can be adjusted as needed, and the use is more flexible.

DETAILED DESCRIPTION

[0023] The preferred embodiments of the present application will be described below with reference to the accompanying drawings. Those skilled in the art will appreciate that the embodiments are only used to explain the technical principles of the present application and are not intended to limit the scope of protection of the present application. Those skilled in the art can make adjustments as needed to adapt to specific application occasions. For example, although the description in the specification is combined with the cabinet machine, the present application can obviously be applied to other forms of air conditioning systems, for example, wall-mounted air conditioners, ceiling air conditioners, etc. all fall within the scope of protection of the present application.

In addition, the terms "first", "second" are only for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0025] Although the steps of the control method of the present application are described in a specific order in this application, these orders are not limiting, and those skilled in the art can perform the related steps in different orders without deviating from the basic principles of the present application.

[0026] To solve the problem that the existing air conditioner cannot balance fast temperature adjustment, energy saving and user comfort, the present application proposes a drainage mixed air conditioning system and a drainage mixed air method. The negative pressure drainage can increase the air volume by several times, greatly increase the air volume and neutralize the temperature of the main airflow without increasing the energy consumption, which not only ensures fast temperature adjustment, but also improves the air conditioning efficiency and avoids the discomfort caused by the direct blowing of the air to the human body.

[0027] As shown in Figure 1 and Figure 2 , the embodiment of the present application discloses a drainage mixed air conditioning system, which comprises a base 10, an air conditioner main machine 20 and a functional machine 30. As shown in Figure 1 , the air conditioner main machine 20 and the functional machine 30 are arranged side by side on the base 10 with a certain interval and have substantially the same air outlet direction, a drainage channel 40 is formed between the air conditioner main machine 20 and the functional machine 30, a complete evaporative condensation system (to be described in detail below) is arranged in the air conditioner main machine 20 to deliver cold air or hot air to the indoor as needed, a airflow circulation system (specifically a fan communicating with the indoor or outdoor) is arranged in the functional machine 30 to provide auxiliary airflow, and the functional machine 30 is movably arranged on the base 10. Figure 2

[0028] ​When the air conditioning system is in refrigeration or heating operation, the air outlet of the air conditioning host 20 blows the main air flow, and the air outlet of the function machine 30 blows the auxiliary air flow. Because the flow rates of the main air flow and the auxiliary air flow are large, according to Bernoulli's theorem, a negative pressure area is formed between the main air flow and the auxiliary air flow. One end of the flow guide channel 40 is located in the negative pressure area, so that a pressure difference is formed between the two ends of the flow guide channel 40. The air flow flows from the end with higher air pressure to the end with lower air pressure in the flow guide channel 40, and is mixed with the main air flow and the auxiliary air flow, so that the overall air volume is doubled. Therefore, the cold air or hot air can be diffused faster in the room, and the refrigeration or heating efficiency can be improved. At the same time, for the power consumption of the air conditioning system, this way of improving the air flow does not need to increase the power of a single fan. Compared with the traditional way of improving the power of the fan, the air conditioning system of the present application is more energy-saving, can greatly increase the air volume without increasing the energy consumption, and improves the air conditioning efficiency. In addition, by mixing with the auxiliary air flow, the temperature of the main air flow is neutralized (lowered in heating and raised in refrigeration), avoiding the discomfort caused by direct blowing to the human body. Furthermore, by adjusting the position of the function machine 30, the size of the air flow in the flow guide channel 40 can also be controlled, so that the air volume and the mixing degree can be adjusted as needed, and the use is more flexible.

[0029] It should be noted that although in the present embodiment, the function machine 30 is movably arranged on the base 10, and the relative movement is formed by moving the function machine 30 to adjust the air volume and the mixing degree. However, this is not limiting, in some other embodiments not shown in the figure, the air conditioning host 20 can be movably arranged on the base 10, and the relative movement is formed by moving the air conditioning host 20, or the function machine 30 and the air conditioning host 20 can be movably arranged on the base 10, and the relative position change is formed by moving both of them.

[0030] In addition, although Figure 1 the function machine 30 in the above embodiment is arranged on the left side of the air conditioning host 20, this positional relationship is not fixed, and those skilled in the art can adjust it as needed to adapt to specific application occasions. For example, the function machine 30 can also be arranged on the right side of the air conditioning host 20, etc. Furthermore, "the directions of the air outlets are substantially the same" means that the air outlets of the function machine 30 and the air conditioning host 20 are directed to the same direction, but the opening angles do not need to be exactly the same. In fact, in order to realize the flow guide and air mixing, under the premise that the directions of the air outlets are substantially the same, the angles of the main air flow and the auxiliary air flow need to be changed by adjusting the air outlet swing leaf and other mechanisms, so that they intersect to a certain extent.

[0031] As Figure 2As shown, the air conditioner host 20 is provided with a first air outlet 21 and a first air return 22, wherein the first air outlet 21 is provided with a first sensor (not shown in the figure), and the first sensor can detect the air outlet temperature of the first air outlet 21; the air conditioner host 20 is internally provided with a heat exchange air duct 23 communicating the first air outlet 21 and the first air return 22, and the air conditioner host 20 is also provided with a complete evaporative condensing system, wherein the evaporative condensing system includes an evaporator 25 and a fan 24 provided in the heat exchange air duct 23, and a compressor, a throttle valve and other components not shown in the figure, the evaporator 25 is located between the first air return 22 and the fan 24, and the return air is heated or cooled by the evaporator 25, and then blown out from the first air outlet 21 by the fan 24, so as to realize the delivery of cold air or hot air to the indoor according to the needs.

[0032] The functional machine 30 is provided with a second air outlet 31 and an air inlet (not shown in the figure), and the functional machine 30 is internally provided with an air duct communicating the second air outlet 31 and the air inlet, and the air duct is provided with an air circulation system, such as a fan (not shown in the figure), and through the air circulation system, the functional machine 30 can deliver the indoor or outdoor air flow to the indoor through the second air outlet 31. In this regard, it should be pointed out that the air inlet of the functional machine 30 can be in communication with the outdoor or the indoor, when it is in communication with the outdoor, the air circulation system of the functional machine 30 is a fresh air system. Conversely, when it is in communication with the indoor, the air circulation system of the functional machine 30 is an indoor air circulation system. In the preferred embodiment of the present application, the air circulation system of the functional machine 30 is a fresh air system, and the advantage of using the fresh air system is that it can provide fresh air, thereby improving the indoor air quality. The following description of the functional machine 30 will be made in combination with the fresh air system.

[0033] Continuing to refer to Figure 1 and 2 , the first air outlet 21 and the second air outlet 31 are oriented in substantially the same direction, and the first end of the drainage channel 40 is located between the first air outlet 21 and the second air outlet 31, when the air conditioning system is in cooling or heating operation, the first air outlet 21 blows out the main air flow, and the second air outlet 31 blows out the auxiliary air flow, due to the high speed of the two air flows, according to Bernoulli's theorem, a negative pressure area will be formed between the first air outlet 21 and the second air outlet 31, so that the air flow flows from the second end of the drainage channel 40 to the first end of the drainage channel 40, and mixes with the main air flow and the auxiliary air flow, so that the overall air volume is doubled, and the cold or heat can be more quickly spread in the indoor, thereby improving the cooling or heating efficiency. As compared with the traditional way of increasing the power of the fan 24, the air conditioning system of the present application is more energy-saving, realizes a large increase in air volume without increasing energy consumption, and improves the air conditioning efficiency.

[0034] It should be noted that in the present embodiment, the air conditioning system is a cabinet system, the base 10 is the base (not shown in the figure) of the cabinet system, the base is provided with a sliding rail (not shown in the figure), and the functional machine 30 is slidably arranged on the base along the sliding rail. By providing the sliding rail, the sliding of the functional machine 30 on the base can be realized, and the relative position with the air conditioning main machine 20 is adjusted by sliding. In the present embodiment, the functional machine 30 moves forward and backward in the air outlet direction of the air conditioning main machine 20, i.e. moves up and down in the middle. Figure 2

[0035] As shown in Figure 2 , the functional machine 30 comprises an air guiding channel 34, which is located inside the functional machine 30 and is independent of the auxiliary air flow duct inside the functional machine 30, so as to avoid air flow interference; the air inlet end of the air guiding channel 34 is located on the side surface of the functional machine 30, and the air outlet end of the air guiding channel 34 is located at the position of the second air outlet 31. The air outlet end of the air guiding channel 34 is communicated with the air guiding port 32, and the air guiding port 32 is provided with a movable adjusting plate 33 to adjust the opening degree of the air guiding port 32. Figure 2 As can be seen from the figure, the air guiding port 32 is located on both sides of the second air outlet 31. In the process of blowing the auxiliary air flow from the second air outlet 31, since the flow speed of the auxiliary air flow is fast, according to Bernoulli's theorem, a negative pressure area will be formed on both sides of the second air outlet 31, so that the air flow on both sides of the functional machine 30 flows to the position of the second air outlet 31 through the air guiding channel 34 and the air guiding port 32, and mixes with the auxiliary air flow to form a stronger air flow, so that the air volume is doubled. This way of improving air flow does not need to increase the power of a single fan 24, so it will not increase additional power consumption. In addition, since the auxiliary air flow is introduced from the outside, it is outdoor fresh air, and the temperature of the air outlet is greatly different from that of the indoor. By setting the air guiding port 32, the indoor air flow and the outdoor fresh air can be mixed, the temperature difference between the outdoor fresh air and the indoor air is reduced, and the refrigeration and heating effect of the air conditioner is improved.

[0036] Regarding the air guiding port 32, it should be noted that although it is described here that the opening degree of the air guiding port 32 is adjusted by moving the adjusting plate 33, this is not limiting, and under the premise that the opening degree of the air guiding port 32 can be adjusted, any appropriate structure can be adopted as needed by those skilled in the art. For example, a rotatable air deflector can be provided at the air guiding port 32 to adjust the opening degree, or a switch valve can be used to adjust, etc. Such a change in the adjusting mechanism does not deviate from the principles and scope of the present application.

[0037] ​Further, in addition to the first temperature sensor arranged at the first air outlet 21 of the air conditioner main unit 20, the air conditioner system of the present application further comprises a second temperature sensor (not shown in the figure) arranged at the second air outlet 31 of the functional unit 30 for detecting the air outlet temperature of the functional unit 30, and a controller (not shown in the figure) capable of controlling the functional unit 30 to move on the base according to the detection value of the first temperature sensor and / or capable of controlling the adjustment plate 33 to move so as to adjust the opening degree of the air inlet 32 according to the detection value of the second temperature sensor. By arranging the first temperature sensor and the second temperature sensor, the position of the functional unit 30 can be controlled according to the air outlet temperature of the air conditioner main unit 20 so as to adjust the size of the overall air volume, and according to the air outlet temperature of the functional unit 30, the opening degree of the air inlet 32 is adjusted to control the difference between the fresh air and the indoor temperature, so that the indoor temperature can quickly reach the predetermined temperature.

[0038] In the second aspect, the present application further discloses a method for air guiding and mixing of the above-mentioned air conditioner system, which comprises the following steps:

[0039] detecting the air outlet temperature of the air conditioner main unit 20;

[0040] determining a first difference between the air outlet temperature of the air conditioner main unit 20 and the predetermined indoor temperature;

[0041] controlling the position of the functional unit 30 relative to the air conditioner main unit 20 on the base 10 according to the first difference.

[0042] By controlling the position of the functional unit 30 relative to the air conditioner main unit 20 on the base 10, the air volume in the air guiding channel 40 and the mixing degree of the main air flow and the auxiliary air flow can be changed, thereby adjusting the overall air volume and the air outlet temperature.

[0043] As shown in the figure, specifically, the step of "controlling the position of the functional unit 30 relative to the air conditioner main unit 20 on the base 10 according to the first difference" specifically comprises: Figure 3 if the first difference is greater than a first set threshold, controlling the functional unit 30 to move to a position where the air outlet is flush with the air outlet of the air conditioner main unit 20; and / or if the first difference is less than the first set threshold, controlling the functional unit 30 to move to a position behind the air conditioner main unit 20. And when the first difference is less than the first set threshold, the distance by which the functional unit 30 moves backward relative to the air conditioner main unit 20 is inversely proportional to the size of the first difference.

[0044]

[0045] ​Specifically, when the functional machine 30 is in the position where the air outlet is flush with the air outlet of the air conditioner main machine 20, the air volume in the flow channel 40 and the mixing degree of the main airflow and the auxiliary airflow are the largest, therefore, if the first difference between the air outlet temperature of the air conditioner main machine 20 and the predetermined indoor temperature is greater than the first set threshold, it indicates that the actual indoor temperature is greatly different from the user's desired value, and rapid cooling or heating is needed, so the functional machine 30 is controlled to move to the position where the air outlet is flush with the air outlet of the air conditioner main machine 20. On the contrary, if the first difference between the air outlet temperature of the air conditioner main machine 20 and the predetermined indoor temperature is less than the first set threshold, it indicates that the actual indoor temperature is not greatly different from the user's desired value, and rapid cooling or heating is not needed, so the functional machine 30 is controlled to move to the position behind the air conditioner main machine 20, so as to reduce the air volume in the flow channel 40 and the mixing degree of the main airflow and the auxiliary airflow. Accordingly, the more the functional machine 30 moves to the position behind the air conditioner main machine 20, the smaller the air volume in the flow channel 40 and the mixing degree of the main airflow and the auxiliary airflow, therefore, when the first difference is less than the first set threshold, the distance that the functional machine 30 moves to the position behind the air conditioner main machine 20 is inversely proportional to the size of the first difference.

[0046] For example, the first set threshold can be 5℃. Accordingly, when the first temperature difference is not less than 5℃, it indicates that the greater the difference between the air outlet temperature of the air conditioner main machine 20 and the predetermined indoor temperature, the greater the air volume needed, then the functional machine 30 is moved to the position where the air outlet is flush with the air outlet of the air conditioner main machine 20, the negative pressure formed is the strongest, and the air volume in the flow channel 40 is the largest, thereby facilitating rapid cooling or heating. If the first difference is less than 5℃, it indicates that the air outlet temperature of the air conditioner main machine 20 is close to the predetermined indoor temperature, then the functional machine 30 is controlled to move to the position behind the air conditioner main machine 20, so as to reduce the negative pressure, thereby reducing the air volume in the flow channel 40 and the overall air volume. In the preferred embodiment, the distance that the functional machine 30 moves to the position behind the air conditioner main machine 20 and the size of the first difference can be determined by the following formula:

[0047] S = 100(1 -△t / 5), unit: mm, wherein S is the retreat distance of the functional machine 30, and△t is the first difference.

[0048] As can be seen from the above description, if the first difference is large, it indicates that the indoor temperature gradually deviates from the predetermined indoor temperature, therefore, the air volume needs to be increased, the retreat distance of the functional machine 30 is shortened, the air volume in the flow channel is kept, thereby increasing the overall air volume and making the temperature approach the predetermined indoor temperature as soon as possible. On the contrary, if the first difference is small, it indicates that the indoor temperature is about to reach the predetermined temperature, and the air volume does not need to be so large, therefore, the functional machine 30 needs to be moved a little bit backward, so as to reduce the air volume in the flow channel 40, thereby reducing the overall air volume.

[0049] Further, as shown in FIG. 2, the functional machine 30 can be controlled to move to the position behind the air conditioner main machine 20, so as to form a flow channel 40.Figure 4 As shown, when the air flow circulation system in the functional machine 30 is a fresh air system, the functional machine 30 further comprises a fresh air inlet 32 close to the air outlet thereof, and the method of air flow mixing further comprises the following steps:

[0050] detecting the air outlet temperature of the functional machine 30, specifically by a second temperature sensor arranged at the second air outlet 31; determining a second difference between the air outlet temperature of the functional machine 30 and the outdoor temperature; and controlling the opening degree of the fresh air inlet 32 according to the second difference, specifically by controlling the movement of the adjusting plate 33 to control the covering degree of the fresh air inlet 32, thereby controlling the opening degree of the fresh air inlet 32. By adjusting the opening degree of the fresh air inlet 32, the size of the indoor air flow can be controlled, thereby adjusting the temperature of the mixed air after the indoor air flow mixes with the outdoor fresh air, reducing the temperature difference between the outdoor fresh air and the indoor air, and thereby improving the cooling and heating effect of the air conditioner.

[0051] Further, the step of "controlling the opening degree of the fresh air inlet 32 according to the second difference" specifically comprises: if the second difference is greater than a second set threshold, adjusting the opening degree of the fresh air inlet 32 to the maximum; and / or if the second difference is less than the second set threshold, adjusting the opening degree of the fresh air inlet 32 to be less than the maximum. Further, when the second difference is less than the second set threshold, the opening degree of the fresh air inlet 32 is proportional to the size of the second difference.

[0052] As an example, the second set threshold can be 3°C. Accordingly, if the second difference between the air outlet temperature of the functional machine 30 and the outdoor temperature is not less than 3°C, it means that the temperature difference between indoor and outdoor is large, and the temperature difference of the outdoor introduced fresh air needs to be reduced, so the opening degree of the fresh air inlet 32 needs to be adjusted to the maximum, so that the mixing amount of indoor air and fresh air is maximized, the temperature difference between fresh air and indoor temperature is maximized, and the indoor temperature can quickly reach the preset temperature. If the second difference between the air outlet temperature of the functional machine 30 and the outdoor temperature is less than 3°C, it means that the air outlet temperature of the functional machine 30 is close to the outdoor fresh air temperature, so the opening degree of the fresh air inlet 32 can be reduced, thereby reducing the indoor air flow. Further, the smaller the second difference between the air outlet temperature of the functional machine 30 and the outdoor temperature, the smaller the opening degree of the fresh air inlet 32, so when the second difference between the air outlet temperature of the functional machine 30 and the outdoor temperature is less than the second set threshold, the opening degree of the fresh air inlet 32 is proportional to the size of the second difference.

[0053] In a preferred embodiment, the relationship between the opening degree of the fresh air inlet 32 and the second difference can be determined by the following formula:

[0054] S = 20(1 -△t / 3), unit: mm, wherein S is the retreat distance of the functional machine 30, and△t is the second difference.

[0055] From the above description, it can be seen that if the second difference is small, it indicates that the temperature difference between the indoor temperature and the outdoor fresh air temperature is small, so the mixing of indoor air and fresh air can be reduced, and therefore the opening degree of the air inlet 32 is smaller. Conversely, if the second difference is large, it indicates that the temperature difference between the indoor temperature and the outdoor fresh air temperature is large, and the mixing amount of indoor air and fresh air needs to be increased to reduce the temperature difference, and therefore the opening degree of the air inlet 32 is increased, the amount of indoor air introduced by the air inlet 32 is increased, and the temperature of the overall air is adjusted.

[0056] So far, the technical solutions of the present application have been described in combination with the preferred embodiments shown in the drawings, but those skilled in the art can easily understand that the protection scope of the present application is obviously not limited to these specific embodiments. Those skilled in the art can make equivalent changes or replacements to the related technical features without departing from the principles of the present application, and the technical solutions after the changes or replacements will fall within the protection scope of the present application.
