Specifically, for the air conditioning system shown in this embodiment, the evaporator 9 in the existing air conditioning inner unit is installed in the outer air duct arranged outdoors, the air conditioning outer unit 12 is connected with the evaporator 9 through the refrigerant pipeline 11 in a closed loop, and a fan is installed in the outer air duct to cool or heat the indoor environment, so that the occupation of the indoor space is greatly reduced, meanwhile, when the air conditioning system is started to operate, the air sucked from the first indoor space 1 by the outer air duct under the action of the fan, after cooling or heating by the evaporator 9, on one hand, the cooled or heated fresh air returns to the first indoor space 1 at a relatively high flow rate and a relatively high air speed, so that the replacement efficiency of the air in the first indoor space 1 is ensured, and on the other hand, as the air in the first indoor space 1 is continuously sucked, the cooled or heated fresh air is continuously input into the second indoor space 2, so that the air pressure difference is generated between the two indoor rooms, and the air pressure difference formed between the first indoor space 1 and the second indoor space 2 can be accelerated, so that the flowing of the cooled or heated fresh air can be conveniently regulated and controlled.
It should be noted here that the first compartment 1 and the second compartment 2 are each represented as a room in a room, e.g. a living room, a bedroom, a study room, etc. The first compartment 1 and the second compartment 2 may be provided with a switch door 14 as shown in fig. 1, and the communication state between the first compartment 1 and the second compartment 2 may be controlled by the switch door 14, and it is obvious that the first compartment 1 and the second compartment 2 may also be communicated by other rooms in the room, and the present invention is not limited specifically.
Meanwhile, the evaporator 9 is a heat exchange device known in the art, and is connected with the air conditioner external unit 12 in a closed loop through a refrigerant pipeline 11 to form a refrigerant circulation system of the air conditioner known in the art, wherein the air conditioner external unit 12 is internally provided with a compressor, a condenser, a throttling element and a four-way valve, and accordingly, the compressor, the evaporator 9, the throttling element, the condenser and the four-way valve can be connected through the refrigerant pipeline 11 to form a closed loop, so that the evaporator 9 can be used for heating fresh air flowing in an external air duct and refrigerating fresh air flowing in the external air duct under the switching of the four-way valve. Of course, the evaporator 9 may be connected to a waste heat generating device known in the art through a circulation pipeline, for example, the waste heat generating device may be a solar heat collector or a surface water heat exchanger for supplying heat, and high-temperature steam or hot water is circularly supplied to the evaporator 9 through the circulation pipeline, the waste heat generating device may also be a cooling tower or a buried pipe heat exchanger for supplying cold, and low-temperature cooling water is circularly supplied to the evaporator 9 through the circulation pipeline, so as to realize reutilization of low-grade energy and achieve better energy-saving effect.
In addition, in this embodiment, the air inlet 7 is not limited to be disposed in the first compartment 1, and the air outlet 8 is not limited to be disposed in the first compartment 1 or the second compartment 2, and the plurality of air inlets 7 may be disposed in a plurality of rooms in the room respectively, and correspondingly, the plurality of air outlets 8 may be disposed in other rooms in the room respectively, so that when the air conditioning system is started to work, an air pressure difference may be formed between different rooms in the room, so as to accelerate the diffusion rate of the air after heat exchange between different rooms in the room, thereby being convenient for improving the effect of regulating the indoor environment as a whole. In practical design, an air valve can be arranged at the corresponding air inlet 7 or air outlet 8 of each room in the room to meet the independent regulation and control requirements of air flow of each room in the room.
In order to ensure the air suction and air supply effects of the outer air duct on each indoor room and facilitate the installation and use of the fans in the outer air duct, the fans are preferably axial fans, and the number and positions of the axial fans are not particularly limited. Obviously, the air supply efficiency of the axial flow fan is far higher than that of the axial flow fan, so that the indoor conveying capacity and conveying speed of the fresh air after refrigeration or heating can be ensured, and the diffusion efficiency of the fresh air among different rooms in a room can be further ensured.
In one of the preferred embodiments, the air outlet 8 is intended to be formed around a window 13 of the second compartment 2 or the first compartment 1.
Specifically, the fresh air for cooling or heating output from the air outlet 8 is discharged to the area where the window 13 is located. Since, in order to ensure a good indoor ventilation and illumination effect, each room of the home is usually provided with a window, it is obvious that the air flow entering the room from the outside through the window is perpendicular to the plane in which the window is located, or the main flow direction of the air flow is perpendicular to the plane in which the window is located, so that the blowing action of the air flow passing the window 13 perpendicularly can be utilized to assist the dispersion of fresh air in the indoor space.
Preferably, the outer air duct in the embodiment comprises a first air duct 3 and a second air duct 4, one end of the first air duct 3 is communicated with one end of the second air duct 4 through an evaporation chamber 10, an evaporator 9 is arranged in the evaporation chamber 10, an axial flow fan is arranged in the first air duct 3 and/or the second air duct 4, an air inlet 7 is arranged at one end of the first air duct 3, which is far away from the second air duct 4, and an air outlet 8 is arranged at one end of the second air duct 4, which is far away from the first air duct 3.

Of course, an axial fan may be separately installed in the first air duct 3 or the second air duct 4, which is not particularly limited herein.
At the same time, by arranging the evaporator 9 in the evaporation chamber 10, on the one hand a stable installation of the evaporator 9 is facilitated, and on the other hand a larger volume of fresh air can be accommodated through the evaporation chamber 10, so that a better heat exchange of the evaporator 9 with the fresh air in the evaporation chamber 10 is achieved. As shown in fig. 1, the present embodiment further provides the evaporation chamber 10 on the wall of the house,
Preferably, in another embodiment, the plurality of air outlets 8 are arranged around the edge of the window 13 to form a plurality of air outlet surfaces communicated with the periphery of the window 13, and the plurality of air outlet surfaces are used for outputting air flow parallel to the plane of the window 13, and the air flow forms an air wall on the inner side of the window 13, wherein the inner side of the window 13 refers to the side surface of the window 13 close to the room.
Specifically, as shown in fig. 1, one end of the second air duct 4 away from the first air duct 3 is arranged around four sides of the window 13, and the plurality of air outlets 8 may be divided into four groups and respectively disposed on the second air duct 4 corresponding to the four sides of the window 13. Therefore, when the air outlet direction of the air outlet 8 is parallel to the plane where the window 13 is located, because the four groups of air outlets 8 all output fresh air towards the middle part of the window 13, an air wall parallel to the window 13 is formed in the second compartment 2. When the window 13 is opened, the wind flow conveyed from the window 13 into the second compartment 2 directly acts on the wind wall, so that the diffusion efficiency of the fresh air conveyed from the air outlet 8 into the second compartment 2 in the room is greatly improved.
Meanwhile, the fresh air output by the air outlets 8 forms an air wall at the inner side of the window 13, so that the condition that high-speed fresh air with a large capacity is directly conveyed into the second room 2 is effectively avoided, the human body is prevented from being directly blown, discomfort of the human body is caused, and the comfort experience of the household life of residents is further enhanced.
Preferably, as shown in fig. 2, in this embodiment, one of opposite sides of the evaporation chamber 10 is provided with a fresh air inlet 101 and a fresh air outlet 102 which are oppositely arranged, and the other opposite side is provided with a refrigerant inlet 103 and a refrigerant outlet 104 which are oppositely arranged, wherein the fresh air inlet 101 is communicated with one end of the first air duct 3, the fresh air outlet 102 is communicated with one end of the second air duct 4, the refrigerant inlet 103 and the refrigerant outlet 104 can respectively form closed loop connection with the air conditioner external unit 12 through the refrigerant pipeline 11, the evaporator 9 comprises a heat exchange tube bundle 91 and a fin group 92, the heat exchange tube bundle 91 and the fin group 92 are inserted into a whole, one end of the heat exchange tube bundle 91 is communicated with the refrigerant inlet 103, and the other end is communicated with the refrigerant outlet 104.

Meanwhile, the refrigerant inlet 103 is disposed at the upper side of the evaporation chamber 10, and the refrigerant outlet 104 is disposed at the lower side of the evaporation chamber 10, so that when the air conditioner outdoor unit 12 works in a closed loop system formed by the refrigerant pipeline 11 and the evaporator 9, the evaporator 9 can conduct heat to the circulating refrigerant, so as to achieve the purpose of heating or refrigerating the fresh air passing through the surface of the evaporator.
It should be noted here that, for the evaporator 9, copper tubes with better heat conductivity may be used for each heat exchange tube in the heat exchange tube bundle 91, and copper fins, steel fins, aluminum fins, or steel-aluminum composite fins may be used for each fin 15 in the fin group 92, which is not particularly limited herein.
Preferably, in this embodiment, a first chamber 108 and a second chamber 109 are disposed in the evaporation chamber 10, and the evaporator 9 is installed in the heat exchange chamber 106 corresponding to the first chamber 108 and the second chamber 109, where the first chamber 108 communicates with the refrigerant inlet 103 and one end of the heat exchange tube bundle 91, and the second chamber 109 communicates with the refrigerant outlet 104 and the other end of the heat exchange tube bundle 91.
Specifically, as shown in fig. 2, by arranging the first chamber 108 and the second chamber 109, the integrated fixed installation of the two ends of the heat exchange tube bundle 91 can be realized, the installation structure of the heat exchange tube bundle 91 is greatly simplified, the first chamber 108 can uniformly convey the refrigerant from one end of the heat exchange tube bundle 91, the second chamber 109 uniformly recovers the refrigerant after heat exchange from the other end of the heat exchange tube bundle 91, and the uniformity of refrigerant conveying in each heat exchange tube is ensured.
Preferably, as shown in fig. 2, in order to ensure that the fresh air exchanges heat with the fin group 92 well, the fin group 92 in this embodiment includes a plurality of fins 15 that are arranged in a stack at a fixed interval, so that the fresh air can pass through the gaps between any two adjacent fins 15 and contact with the surface of each fin 15 is achieved.
Further, as shown in fig. 3, each fin 15 is provided with a plurality of tube holes 151 and a plurality of protrusions 152, and the tube holes 151 and the protrusions 152 are arranged in an array on the fin 15. Thus, when the plurality of fins 15 are stacked and arranged in the fin group 92, a plurality of tube holes arranged in an array are also formed in the fin group 92 so that the fin group 92 is inserted integrally with the heat exchange tube bundle 91 and constitutes the evaporator 9 shown in the present embodiment.
Meanwhile, as shown in fig. 3, since the plurality of protrusions 152 are provided on the surfaces of the fins 15, when the fresh air flows in the gaps between two adjacent fins 15, the surface of each protrusion 152 forms a coanda effect (coanda effect) on the fresh air, which is greatly beneficial to the contact heat exchange between the fresh air and the surfaces of the fins 15.
Preferably, the protrusions 152 are in a drop shape in this embodiment, the large ends of the protrusions 152 face the fresh air inlet 101, and the small ends of the protrusions 152 face the fresh air outlet 102, and/or a plurality of protrusions 152 are arranged on the same side of the fins 15, and each protrusion 152 is located between two adjacent tube holes 151.
Specifically, because the curvature of the big end of the drop-shaped protrusion 152 is small and the curvature of the small end is large, when the fresh air flows from the big end of the protrusion 152 to the small end, the wall attaching effect is more easily generated at the big end of the protrusion 152 and the small end of the protrusion 152 diverges. Further, since the plurality of protrusions 152 are disposed on the same side of the fins 15, when the fresh air flows in the gaps between the two adjacent fins 15, the fresh air flows forward along the serpentine curve, which is greatly beneficial to the contact between the fresh air and the surfaces of the two adjacent fins 15, so that the contact heat exchange is better performed.
In addition, by arranging each protrusion 152 between two adjacent pipe holes 151, the fresh air is convenient to contact and exchange heat with each heat exchange pipe in the forward conveying process.
Preferably, the present embodiment further provides an air conditioning house, including the air conditioning system described in the foregoing embodiment.

Of course, the air inlet 7 may also be disposed in the second compartment 2, and correspondingly, the air outlet 8 may also be disposed in the first compartment 1, which is not particularly limited.
Therefore, when the air conditioning system starts to operate, as the air in the first compartment 1 is continuously sucked, the sucked air is continuously input into the second compartment 2 after heat exchange through the evaporator 9, so that air pressure difference is generated between two rooms in the room, and the diffusion rate of the heat exchanged air between different rooms in the room is accelerated.
It should be noted here that the opening and closing door 14 shown in fig. 1 may be provided between the first compartment 1 and the second compartment 2, and the first compartment 1 and the second compartment 2 may also be communicated by a plurality of rooms communicating with each other in the room, which is not particularly limited herein.
