Description

Technical Field

[0001] The utility model relates to the technical field of air conditioning equipment, in particular to an air conditioning system. Background Art

[0002] The existing air conditioning system includes an air supply device for supplying air to the room, and the air supply device includes an air supply part, an air outlet part, and a pipe connecting the air supply part and the air outlet part. The air outlet part includes a plurality of air outlet ducts and an air outlet disposed on the air outlet duct and facing the room. There is a certain distance between adjacent air outlet ducts to form an air induced duct. When the air supply device is in operation, the air is blown to the air outlet part through the pipe under the action of the air supply part, and blown to the room through the plurality of air outlet ducts of the air outlet part. The air is blown out through the plurality of air outlet ducts, so that a low pressure area is formed on the upstream side of the plane where the air outlet is located in the indoor space. As a result, the air close to the air outlet in the indoor space will flow to the low pressure area, and driven by the air flow blown out of the air outlet, it will be blown to one side of the air outlet through the air induced duct. As a result, the air volume can be supplemented while supplying air evenly to the room, saving energy.

[0003] As described in the background of the air conditioning system, the higher the wind speed at the air outlet of the air supply device, the greater the air volume, the lower the air pressure on the upstream side of the air outlet, and the greater the pressure difference with the air pressure in the indoor space, the more air enters the induced draft duct, and the more air volume is supplemented. However, on the other hand, the wind blown out at high speed may make the user feel uncomfortable. In addition, if the wind speed at the air outlet is too high, it may cause noise. In order to take into account the comfort of air supply, the wind speed of the air supply device is generally limited. Therefore, even if an induced draft duct is set up, the amount of air supplemented by the backflow formed by the pressure difference alone is small. Utility Model Content

[0004] In order to solve the above-mentioned problems, the utility model provides an air conditioning system, in which the air blown out from the active air supply port is sucked into the induced air space and blown into the room through the induced air duct. Even if the wind speed at the air outlet of the air supply device is low, the air volume supplied through the active air supply port can also provide sufficient air volume. As a result, it is possible to achieve uniform air supply while improving the air supply efficiency, and have both high air supply comfort and low noise performance.

[0041] like Figures 1 to 5 As shown, the utility model provides an air conditioning system, including an air supply device 1 and an active air supply device 2 for supplying air indoors. The so-called air supply to the indoors includes but is not limited to supplying air to one indoor space, or supplying air to multiple indoor spaces. For ease of description, the following embodiments are described with the air supply device 1 and the active air supply device 2 installed on the ceiling. In the present disclosure, the air supply device 1 or the active air supply device 2 can also be set on the wall or other positions indoors.

[0042] The air supply device 1 includes an air inlet portion, an air outlet portion 12 and an air supply portion 11 .

[0043] The air inlet is used for air to enter the air supply device 1, and includes an air inlet formed by an opening for air to enter. The air source can be indoor air, outdoor air, or both indoor air and outdoor air. In this embodiment, the air inlet includes a return air port 13 formed by an opening for indoor air to enter. In other embodiments, the air inlet may also include an outdoor air inlet for outdoor air to enter.

[0044] The air outlet 12 is used to blow the air in the air supply device 1 into the room, is arranged in the indoor space, and includes more than two air outlet units 121. The so-called more than two refers to the case where two are included. When there are multiple air outlet units 121, the multiple air outlet units 121 are arranged at intervals in the horizontal direction.

[0045] The air outlet unit 121 also includes an air outlet unit air inlet 1215 for air to enter the air outlet unit 121, and an air outlet duct connecting the air outlet unit air inlet 1215 and the air outlet 1214. In this embodiment, the air outlet unit 121 is in the shape of a hollow rectangular parallelepiped, and the length of the air outlet unit 121 is set according to actual needs. The two ends of the air outlet unit 121 defined along the length direction of the air outlet unit 121 are respectively the first end and the second end of the air outlet unit 121, the first end of the air outlet unit 121 is configured with an air outlet unit air inlet 1215, the air outlet unit air inlet 1215 is connected to the air supply unit 11, and the second end of the air outlet unit 121 is a closed structure.

[0046] The length direction of the air outlet portion 12 is consistent with the length direction of the air outlet unit 121. The two ends of the air outlet portion 12 defined along the length direction of the air outlet portion 12 are respectively the first end and the second end of the air outlet portion 12. The two opposite sides of the air outlet portion 12 defined along the arrangement direction of the plurality of air outlet units 121 are respectively the first side and the second side of the air outlet portion 12.

[0047] like Figure 3 and Figure 4 As shown, the air outlet unit 121 includes a top wall 1211, two oppositely arranged vertical side walls 1212 and two oppositely arranged oblique side walls 1213. It can be understood that the vertical side wall 1212 is perpendicular to the horizontal plane, and the oblique side wall 1213 is at a preset angle to the horizontal plane. One end of the vertical side wall 1212 is connected to the top wall 1211, and the other end is connected to the oblique side wall 1213. Thus, the top wall 1211, the two vertical side walls 1212 and the two oblique side walls 1213 enclose an air outlet duct. In this embodiment, the air inlet 1215 of the air outlet unit is arranged on the vertical side wall 1212. In other embodiments, the air inlet 1215 of the air outlet unit can also be arranged on the top wall 1211.

[0048] At least one air outlet unit 121 is provided with an air outlet 1214, and each air outlet unit 121 may also be provided with an air outlet 1214. The air outlet 1214 is provided on the air outlet unit 121, and the air outlet 1214 is connected to the indoor space for air to be blown into the room. In this embodiment, the air outlet 1214 is provided at the bottom of the air outlet unit 121, that is, the air outlet 1214 is located at one end of the oblique side wall 1213 of the air outlet unit 121 away from the vertical side wall 1212. The ends of the two oblique side walls 1213 away from the vertical side wall 1212 are spaced a certain distance apart, thereby forming an air outlet 1214 between the ends of the two oblique side walls 1213.

[0049] The air outlet 1214 may extend from the first end to the second end of the air outlet unit 121, or may be provided only in a certain section of the air outlet unit 121. For example, the air outlet 1214 may be provided in a range of 1 / 3 to 2 / 3 of the length of the air outlet unit 121, and in the section outside the air outlet 1214, the ends of the two oblique side walls 1213 away from the vertical side wall 1212 are connected.

[0050] It can be understood that the air outlet unit 121 can also be composed of a top wall 1211, two oppositely arranged vertical side walls 1212 and a bottom wall. The top wall 1211 and the bottom wall are arranged in parallel with each other. One end of the vertical side wall 1212 is connected to the top wall 1211, and the other end is connected to the bottom wall. A long strip-shaped air outlet 1214 of a preset size is opened on the bottom wall.

[0051] The air supply unit 11 is used to supply air from the air inlet to the air outlet 1214, and the air supply unit 11 includes an air supply unit and a duct 111. The air supply unit is used to suck air from the air inlet and blow it out to the air outlet 1214. The duct 111 connects the air inlet and the air outlet 12. Specifically, in this embodiment, the duct 111 is connected to the air inlet 1215 of the air outlet unit, so that the air of the air inlet enters the air outlet unit 121 through the duct 111.

[0052] The air outlet portion 12 further includes an air induction space 122 and an air induction channel 123 .

[0053] like Figure 2 and Figure 3 As shown, the induced air space 122 is a space located on the upstream side of the plane where the air outlet 1214 is located and is connected to the indoor space. In this embodiment, the induced air space 122 is located above the top wall 1211 of the air outlet unit 121. In other words, the air conditioning system is installed on the ceiling, and a part of the ceiling is recessed to form a space for accommodating the air outlet 12, or the air outlet 12 is suspended on the ceiling, and there is a certain distance between the ceiling and the top wall 1211 of the air outlet unit 121, forming the induced air space 122. The induced air space 122 includes an induced air outlet connected to the indoor space.

[0054] In this embodiment, the air inlet is arranged on one side of the air outlet. Specifically, the air inlet is arranged on at least one side adjacent to the vertical side wall 1212 where the air inlet 1215 of the air outlet unit is located, that is, the air inlet is located on the first side and / or the second side of the air outlet 12, and an opening is opened on the side wall of the ceiling corresponding to the first side of the air outlet 12 to form the air inlet, or an opening is opened on the side wall of the ceiling corresponding to the second side of the air outlet 12 to form the air inlet.

[0055] An air induction channel 123 is formed between two adjacent air outlet units 121 , and the air induction channel 123 is connected to the air induction space 122 and the indoor space.

[0056] The active air supply device 2 is used to supply air to the room, and the active air supply device 2 includes an active air inlet portion, an active air outlet portion and an active air supply portion.

[0057] The active air inlet is used to supply air into the active air supply device 2, and includes an active air inlet for air to enter. The active air inlet includes an active return air inlet 22 for indoor air to enter. In other embodiments, the active air inlet also includes an outdoor air inlet for outdoor air to enter. To distinguish it from the outdoor air inlet of the air supply device 1, the outdoor air inlet of the active air supply device 2 is defined as an outdoor active air inlet.

[0058] The active air outlet is provided indoors for blowing the air in the active air supply device 2 to the indoors, and includes an active air supply port 21 formed by an opening for supplying air to the indoors. The active air supply port 21 is closer to the air induction space 122 than the air outlet 1214, that is, the distance between the plane where the active air supply port 21 is located and the air induction space 122 is smaller than the distance between the plane where the air outlet 1214 is located and the air induction space 122. In this embodiment, the active air supply port 21 is provided on the side wall of the ceiling corresponding to the first side of the air outlet 12, and the active air supply port 21 is located above the plane where the air outlet 1214 is located.

[0059] The working process of the air conditioning system is described below.

[0060] When the air supply device 1 is in operation, the air supply unit starts to operate, air enters from the air inlet, and under the action of the air supply unit, is blown toward the air outlet 12 along the duct 111. Indoor air enters from the return air port 13, and is blown toward the air outlet 12 along the duct 111. The air is blown toward the air outlet 12 from the duct 111, enters the air outlet unit 121 through the air inlet 1215 of the air outlet unit, and is blown toward the air outlet 1214 along the air outlet duct, and then blown toward the room through the air outlet 1214.

[0061] The air is blown out from the air outlet 1214, which increases the air pressure in the area on the downstream side of the plane where the air outlet 1214 is located, and relatively reduces the air pressure in the area on the upstream side of the plane where the air outlet 1214 is located in the indoor space. Since the induced draft space 122 is provided on the upstream side of the plane where the air outlet 1214 is located, the air pressure in the induced draft space 122 is lower than the air pressure in the area on the upstream side of the plane where the air outlet 1214 is located. Since the induced draft space 122 is connected to the indoor space through the induced draft port, a portion of the air near the air outlet 12 in the indoor space will be sucked into the induced draft space 122 through the induced draft port. Under the attraction of the airflow blown out from the air outlet 1214, the air in the induced draft space 122 will flow to the area on the downstream side of the plane where the air outlet 1214 is located. Since an air duct 123 connected to the air duct space 122 is formed between two adjacent air outlet units 121, the air in the air duct space 122 will be blown to the downstream side of the plane where the air outlet 1214 is located through the air duct 123, and mixed with the air blown out of the air outlet 1214 to be delivered into the room together.

[0062] In the embodiment of the present disclosure, since the active air supply port 21 is closer to the induced air space 122 than the air outlet 1214, when the air pressure in the induced air space 122 is low, the air blown out from the active air supply port 21 will be sucked into the induced air space 122 and blown out into the room through the induced air passage 123. Even if the wind speed at the air outlet 1214 of the air supply device 1 is low, the air volume supplied through the active air supply port 21 can provide sufficient air volume, thereby achieving uniform air supply while improving the air supply efficiency, and having both high air supply comfort and low noise performance.

[0063] Furthermore, in the direction from the air outlet 1214 to the air induction space 122, the active air supply port 21 is closer to the air induction space 122 than the center plane of the air outlet unit 121. The so-called center plane of the air outlet unit 121 refers to the horizontal plane where the center planes of the two vertical side walls 1212 of the air outlet unit 121 are located in the direction from the plane where the air outlet 1214 is located to the air induction space 122. In this embodiment, the active air supply port 21 is located above the center plane of the vertical side wall 1212 of the air outlet unit 121.

[0064] Furthermore, if Figure 1 and Figure 5 As shown, the active air supply port 21 is disposed on one side of the air outlet unit 121 and is disposed facing the air outlet unit 121. In this embodiment, the active air supply port 21 is disposed on one side of the side of the air outlet unit 121 adjacent to the side where the air outlet unit air inlet 1215 is located and is disposed facing the side. For example, the active air supply port 21 is located on the first side of the air outlet portion 12.

[0065] The active air supply unit is used to supply air from the active air inlet to the active air outlet, and includes an active air supply unit and a pipeline. The active air supply unit is used to inhale air from the active air inlet and blow it out to the active air outlet. The pipeline connects the active air inlet and the active air outlet 12.

[0066] In this embodiment, Figure 5 As shown, the active air supply device includes a first active air supply device 3 and a second active air supply device 4. Optionally, the first active air supply device 3 and the second active air supply device 4 are both located on the first side of the air outlet 12. The first active air supply device 3 includes an air processing unit that processes the air flowing through. The so-called processing of the air refers to processing one or more indicators of the temperature, humidity and quality of the air. In this embodiment, the air processing unit includes a refrigeration circuit that can heat or cool the air through heat exchange. The first active air supply device 3 includes an active return air outlet 22 for indoor air to enter, and the first active air supply device 3 also includes a first active air supply outlet 31.

[0067] The second active air supply device 4 includes an outdoor active air inlet connected to the outside for allowing outdoor air to enter. The second active air supply device 4 also includes a second active air supply port 41 .

[0068] It can be understood that a first active air supply port 31 and a second active air supply port 41 are provided on the side wall of the ceiling corresponding to the first side of the air outlet portion 12 .

[0069] Optionally, the return air inlet 13 and the active return air inlet 22 are arranged on the same side of the air outlet 12. The so-called same side refers to a side relative to the air outlet 12, where the return air inlet 13 and the active return air inlet 22 are located on the same side of the air outlet 12. In the present embodiment, the return air inlet 13 and the active return air inlet 22 are both arranged on the side of the air outlet 12 facing the active air supply inlet 21. Specifically, the return air inlet 13 and the active return air inlet 22 are both located on the first side of the air outlet 12, and the return air inlet 13 and the active return air inlet 22 are farther away from the air outlet 12 than the active air supply inlet 21, that is, the horizontal spacing between the return air inlet 13 and the air outlet 12 and the horizontal spacing between the active return air inlet 22 and the air outlet 12 are both greater than the horizontal spacing between the active air supply inlet 21 and the air outlet 12.

[0070] Optionally, the return air port 13 and the active return air port 22 are arranged on opposite sides of the air outlet portion 12. The air outlet portion 12 includes a plurality of air outlet units 121, and along the arrangement direction of the plurality of air outlet units 121, a side adjacent to the head ends of the plurality of air outlet units 121 is a first side of the air outlet portion 12, and a side adjacent to the ends of the plurality of air outlet units 121 is a second side of the air outlet portion 12, the active return air port 22 is located on the first side of the air outlet portion 12, and the return air port 13 is located on the second side of the air outlet portion 12.

[0071] The following lists three embodiments to explain in detail the working process thereof according to the different positions of the return air outlet 13 , the active return air outlet 22 and the active air supply outlet 21 in the air conditioning system.

[0072] Figure 6 A schematic diagram of air flow of an air conditioning system according to a first embodiment of the present invention; Figure 7 A schematic diagram of air flow of an air conditioning system according to a second embodiment of the present invention; Figure 8 This is a partial bottom view of an air conditioning system according to a third embodiment of the present utility model; Fig. 9 This is a second partial bottom view of the air conditioning system according to the third embodiment of the utility model.

[0073] First embodiment

[0074] like Figure 6 As shown, in the first embodiment, the return air port 13 and the active return air port 22 are located on the same side of the air outlet 12. For example, the return air port 13 and the active return air port 22 are both located on the first side of the air outlet 12, and the active air supply port 21 is also located on the first side of the air outlet 12. The other structures of the air conditioning system are as described above and will not be described again here.

[0075] When the air supply device 1 is in operation, the air supply unit starts to operate, air enters from the air inlet, and under the action of the air supply unit, is blown toward the air outlet 12 along the duct 111. Indoor air enters from the return air port 13, and is blown toward the air outlet 12 along the duct 111. The air is blown toward the air outlet 12 from the duct 111, enters the air outlet unit 121 through the air inlet 1215 of the air outlet unit, and is blown toward the air outlet 1214 along the air outlet duct, and then blown toward the room through the air outlet 1214.

[0076] The air is blown out from the air outlet 1214, which increases the air pressure in the area on the downstream side of the plane where the air outlet 1214 is located, and relatively reduces the air pressure in the area on the upstream side of the plane where the air outlet 1214 is located in the indoor space. Since the induced draft space 122 is provided on the upstream side of the plane where the air outlet 1214 is located, the air pressure in the induced draft space 122 is lower than the air pressure in the area on the upstream side of the plane where the air outlet 1214 is located. Since the induced draft space 122 is connected to the indoor space through the induced draft port, a portion of the air near the air outlet 12 in the indoor space will be sucked into the induced draft space 122 through the induced draft port. Under the attraction of the airflow blown out from the air outlet 1214, the air in the induced draft space 122 will flow to the area on the downstream side of the plane where the air outlet 1214 is located. Since an air duct 123 connected to the air duct space 122 is formed between two adjacent air outlet units 121, the air in the air duct space 122 will be blown to the downstream side of the plane where the air outlet 1214 is located through the air duct 123, and mixed with the air blown out of the air outlet 1214 to be delivered into the room together.

[0077] Since the active air supply port 21 is closer to the induced air space 122 than the air outlet 1214, when the air pressure in the induced air space 122 is low, the air blown out from the active air supply port 21 will be sucked into the induced air space 122 and blown out into the room through the induced air passage 123. Even if the wind speed at the air outlet 1214 of the air supply device 1 is low, the air volume supplied through the active air supply port 21 can provide sufficient air volume, thereby achieving uniform air supply while improving the air supply efficiency, and having both high air supply comfort and low noise performance.

[0078] Furthermore, since the active air supply port 21 is closer to the air induced space 122 than the center plane of the air outlet unit 121, when the air is blown out from the active air supply port 21 and flows into the air induced space 122, most of the air can be prevented from interfering with the vertical side wall 1212 of the air outlet unit 121, thereby suppressing the generation of noise and turbulence.

[0079] Furthermore, the active air supply port 21 is arranged facing the air outlet unit 121, so that the air blown out from the active air supply port 21 can enter the air induction space 122 more smoothly, thereby suppressing the generation of noise and turbulence.

[0080] In addition, in this embodiment, the first active air supply device 3 includes an air processing unit. The air heated by the air processing unit is blown out through the first active air supply port 31, and most of it first enters the air induction space 122, and then mixes with the air blown out from the air outlet 1214 to be supplied to the room. As a result, the heated warm air will be evenly mixed with the air at room temperature before being blown into the room, which can prevent the hot air from blowing directly onto the user and causing discomfort. At the same time, it can also make the indoor air heat up faster and more evenly, thereby improving the heating efficiency.

[0081] Similarly, after the air is cooled by the air handling unit, it is blown out through the first active air supply port 31, and most of it first enters the air induction space 122, and is mixed with the air blown out of the air outlet 1214 before being blown into the room. As a result, the cooled cold air is mixed evenly with the air at room temperature before being blown into the room. This can prevent the cold air from blowing directly onto the user, causing discomfort. At the same time, it can also make the indoor air cool faster and more evenly, thereby improving the cooling efficiency.

[0082] In addition, in this embodiment, the second active air supply device 4 includes an outdoor active air inlet, that is, it can send outdoor fresh air into the room. When the outdoor fresh air is blown into the room through the second active air supply port 41, it will first enter the air induction space 122, and then mix with the air at the air outlet 1214 before being blown into the room. In this way, uneven air supply can be avoided, thereby avoiding uneven indoor temperature.

[0083] After the air is blown out from the air outlet 1214, it will flow toward the return air outlet 13. Similarly, a part of the indoor air will flow toward the active return air outlet 22 under the action of the active air supply unit.

[0084] In this embodiment, since the return air outlet 13 and the active return air outlet 22 are arranged on the same side of the air outlet 12, the direction of the airflow flowing from the air outlet 12 to the return air outlet 13 is similar to or even consistent with the direction of the airflow flowing to the active return air outlet 22, thereby suppressing the cross-flow of the two airflows and causing the generation of turbulence.

[0085] Second embodiment

[0086] The second embodiment of the present disclosure is described below, wherein the parts of the structure of the air conditioning system in the second embodiment that are the same as those in the first embodiment are not repeated.

[0087] like Figure 7 As shown, in this embodiment, the return air outlet 13 and the active return air outlet 22 are arranged on two opposite sides of the air outlet 12. The so-called being arranged on two opposite sides of the air outlet 12 means that along the arrangement direction of the plurality of air outlet units 121, one of the return air outlet 13 and the active return air outlet 22 is located on the first side of the air outlet 12, and the other is located on the second side of the air outlet 12. Specifically, in this embodiment, the return air outlet 13 is arranged on the side of the air outlet 12 away from the active air supply outlet 21, and the active return air outlet 22 is arranged on the side of the air outlet 12 close to the active air supply outlet 21. For example, the active air supply outlet 21 and the active return air outlet 22 are located on the first side of the air outlet 12, and the return air outlet 13 is located on the second side of the air outlet 12.

[0088] Since the return air port 13 and the active return air port 22 are located on opposite sides of the air outlet 12, the air blown out from the air outlet 12 is sucked back into the air supply device 1 from the return air port 13. A portion of the indoor air will enter the active air supply device 2 again from the active return air port 22. The two air flows are in opposite directions, thereby preventing the two air flows from crossing and causing turbulence.

[0089] Third embodiment

[0090] The third embodiment of the present disclosure is described below, wherein the same structures as those of the first and second embodiments will not be described again.

[0091] like Figure 8 and Fig. 9 As shown, in this embodiment, the return air outlet 13 and the active return air outlet 22 are located on opposite sides of the air outlet 12, for example, the active air supply outlet 21 and the active return air outlet 22 are located on the first side of the air outlet 12, and the return air outlet 13 is located on the second side of the air outlet 12.

[0092] The return air port 13 and the air outlet 1214 form a first connecting line 5, which is a vertical line from the center point of the return air port 13 to the air outlet 1214. The active return air port 22 and the active air supply port 21 form a second connecting line 6. The second connecting line 6 is a vertical line from the center point of the active return air port 22 to the active air supply port 21. The first connecting line 5 and the second connecting line 6 are parallel to each other.

[0093] like Figure 8 As shown, the active air supply port 21 and the active air return port 22 are located on the first side of the air outlet portion 12 and close to the first end of the air outlet portion 12; the return air port 13 is located on the second side of the air outlet portion 12 and close to the second end of the air outlet portion 12, thereby, the first connecting line 5 and the second connecting line 6 are parallel to each other, and the first connecting line 5 and the second connecting line 6 are separated by a certain distance.

[0094] like Fig. 9 As shown, the active air supply outlet 21 and the active return air outlet 22 are located on the first side of the air outlet 12, the return air outlet 13 is located on the second side of the air outlet 12, and the active air supply outlet 21, the active return air outlet 22 and the return air outlet 13 are all arranged close to the same area in the length direction of the air outlet 12, thus, the first connecting line 5 and the second connecting line 6 are parallel to each other, and the first connecting line 5 and the second connecting line 6 are collinear.

[0095] Thus, when the air blown out from the air outlet 1214 flows toward the return air outlet 13 and the indoor air flows toward the active return air outlet 22, the generation of turbulence caused by the intersection of airflows can be suppressed.
