[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means intended to limit the present invention and its application or use. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] In the description of the present invention, it is necessary to understand that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the drawings. They are only for the convenience of describing the present invention and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the devices or elements referred to must have a specific direction or be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the scope of protection of the present invention. The directional words "inside and outside" refer to the inside and outside relative to the contours of each component itself.

[0031] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0032] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. If not otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of the present invention.

[0033] See also Figure 1-9As shown, an integrated air conditioner includes a first heat exchanger 1, a second heat exchanger 2, a fresh air inlet 3011, a fresh air outlet 3012, an exhaust air inlet 3021, an exhaust air outlet 3022 and a full heat exchange core 3, wherein the full heat exchange core 3 includes a fresh air channel 301 and a return air channel 302, and the integrated air conditioner includes a fresh air flow path and an exhaust air flow path;

[0034] The fresh air flow path sequentially connects the fresh air inlet 3011, the fresh air channel 301, the first heat exchanger 1 and the fresh air outlet 3012, the fresh air inlet 3011 leads to the outdoors, and the fresh air outlet 3012 leads to the indoors; the exhaust air flow path sequentially connects the exhaust air inlet 3021, the return air channel 302, the second heat exchanger 2 and the exhaust air outlet 3022; one of the first heat exchanger 1 and the second heat exchanger 2 is for cooling, and the other is for heating; the integrated air conditioner is also provided with an exhaust air regulating part 7, and indoor air can flow through the second heat exchanger 2 via the exhaust air regulating part 7.

[0035] When the integrated air conditioner is cooling or dehumidifying, the high-temperature refrigerant first flows through the second heat exchanger 2 to release heat, and then flows through the first heat exchanger 1 to absorb heat, that is, the first heat exchanger 1 cools and the second heat exchanger 2 heats; the outdoor air flows through the fresh air channel 301 through the fresh air inlet 3011, and the indoor air enters the return air channel 302 through the exhaust air inlet 3021. In the full heat exchange core 3, the outdoor air and the indoor air complete the heat exchange. Among them, the outdoor air temperature is reduced and then flows through the first heat exchanger 1. After further cooling and dehumidification in the first heat exchanger 1, it enters the room through the fresh air inlet 3011; the indoor air temperature rises after flowing through the full heat exchange core 3, and further absorbs heat when flowing through the second heat exchanger 2 to accelerate the release of coldness by the second heat exchanger 2, and then the indoor air flows out of the room through the exhaust air outlet 3022. In this way, the dehumidification and cooling of the fresh air are achieved.

[0036] When the integrated air conditioner is heating, the high-temperature refrigerant first flows through the first heat exchanger 1 to release heat, and then flows through the second heat exchanger 2 to absorb heat, that is, the first heat exchanger 1 heats and the second heat exchanger 2 cools; the outdoor air flows through the fresh air channel 301 through the fresh air inlet 3011, and the indoor air enters the return air channel 302 through the exhaust air inlet 3021. In the full heat exchange core 3, the outdoor air and the indoor air return complete the heat exchange; wherein, after the outdoor air temperature rises, it flows through the first heat exchanger 1, and is further heated and heated at the first heat exchanger 1, and then enters the room through the fresh air inlet 3011; the indoor air cools down after flowing through the full heat exchange core 3, and further releases heat when flowing through the second heat exchanger 2 to accelerate the second heat exchanger 2 to absorb heat, and then the indoor air flows out of the room through the exhaust air outlet 3022. In this way, fresh air heating is achieved.

[0037] Specifically, when cooling and dehumidifying, the refrigerant releases heat and absorbs cold in the condenser of the second heat exchanger 2. Due to the limited volume of the integrated air conditioner, when the temperature of the outdoor fresh air entering the room does not reach the set temperature, the cooling is insufficient, indicating that the second heat exchanger 2 may be facing insufficient heat exchange, resulting in excessive condensation temperature and condensation pressure, so that the refrigerant does not release enough heat in the second heat exchanger 2, and then the temperature of the refrigerant when flowing through the first heat exchanger 1 is not low enough, affecting the heat exchange of the evaporator of the first heat exchanger 1. At this time, the flow rate of indoor air flowing through the second heat exchanger 2 is increased. Since the indoor air temperature is relatively low, the indoor air with a lower temperature can accelerate the heat exchange efficiency of the second heat exchanger 2 when flowing through the second heat exchanger 2. In this way, the cooling and dehumidification efficiency of the integrated air conditioner is improved, the temperature of the fresh air entering the room is reduced, which is conducive to quickly reducing the indoor temperature.

[0038] The indoor air return flows in the return air channel 302, and the outdoor air fresh air flows in the fresh air channel 301. The return air and the fresh air exchange heat through the full heat exchange core 3, that is, the return air heats or cools the fresh air, recovering the heat or cold of the return air, which is beneficial to reducing energy consumption and plays a role in energy saving and emission reduction. It also improves the performance of the integrated air conditioner.

[0039] The fresh air and the return air can exchange heat and humidity at the same time when passing through the full heat exchange core 3.

[0040] The integral air conditioner also includes an electric control box.

[0041] Preferably, Figure 1 As shown, the exhaust air regulating part 7 includes a regulating inlet and a first outlet 4011 which are interconnected. The first outlet 4011 leads to the inlet of the fresh air passage 301 , and the regulating inlet leads to the room. The opening of the first outlet 4011 is adjustable.

[0042] The air flowing out of the first outlet 4011 can enter the fresh air passage 301 from the inlet of the fresh air passage 301 .

[0043] By providing the exhaust air adjustment unit 7, it is convenient to control the change of the path through which the indoor air flows.

[0044] Specifically, the first outlet 4011 leads to the inlet of the fresh air strip. When the temperature of the air entering the room is too low, part of the indoor air return air flows into the fresh air channel 301 by adjusting the opening of the first outlet 4011, thereby preventing the fresh air temperature in the fresh air channel 301 from being too low, and preventing the full heat exchange core 3 from freezing or frosting. The heat exchange efficiency between the fresh air and the return air through the full heat exchange core 3 is thereby improved. The indoor air flowing out of the first outlet 4011 flows through the full heat exchange core 3 and then flows through the second heat exchanger 2, thereby increasing the heat exchange amount of the second heat exchanger 2, improving the heat exchange efficiency of the second heat exchanger 2, further improving the heat exchange efficiency between the fresh air and the first heat exchanger 1, and ultimately making the temperature of the air entering the room higher or lower. Improve user experience.

[0045] Specifically, when heating, due to the low outdoor temperature, for example, the outdoor temperature is not higher than -5°C, when the low outdoor air flows through the full heat exchange core 3, it may cause the full heat exchange core 3 to freeze; in order to prevent the full heat exchange core 3 from freezing, the first outlet 4011 can be opened, and part of the higher indoor temperature air enters the fresh air duct 301, thereby increasing the temperature in the fresh air duct 301, avoiding ice and frost in the fresh air duct 301, and avoiding freezing of the full heat exchange core 3.

[0046] Preferably, Figure 2-9 As shown, the exhaust air adjustment part 7 further includes a second outlet 4021 , the second outlet 4021 is connected to the adjustment inlet, the second outlet 4021 leads to the outlet of the return air channel 302 , and the opening degree of the second outlet 4021 is adjustable.

[0047] The second outlet 4021 leads to the outlet of the return air passage 302 , and the return air flowing out of the second outlet 4021 and the return air flowing out of the return air passage 302 flow through the second heat exchanger 2 together.

[0048] When heating or cooling, the indoor air return air flows through the second heat exchanger 2 through the second outlet 4021. In this way, the return air with a higher or lower indoor temperature does not flow through the full heat exchange core 3 and directly flows to the second heat exchanger 2 without participating in the heat exchange of the full heat exchange core 3, thereby increasing the heat exchange efficiency of the second heat exchanger 2 and improving the heat exchange efficiency of the refrigerant in the second heat exchanger 2. When the refrigerant flows through the first heat exchanger 1, the heat exchange efficiency of the first heat exchanger 1 is improved, and finally the temperature of the fresh air entering the room is made higher when heating or lower when cooling. By adjusting the effective ventilation area of ​​the opening of the first outlet 4011 and the second outlet 4021, the relationship between the heat exchange efficiency of the full heat exchange core 3 and the degree of heat exchange improvement is balanced. The "opening adjustment" of this application includes fully open and fully closed.

[0049] The exhaust air adjustment part 7 may include an adjustment body and an adjustment plate 5. Figure 2-9As shown, the regulating body 4 is provided with a first hole 401 and a second hole 402, the first outlet 4011 is the outlet of the first hole 401, and the second outlet 4021 is the outlet of the second hole 402. The regulating plate 5 is provided with two first through holes 501 and a second through hole 502, and the regulating plate 5 is rotatably arranged on the regulating body 4. When the regulating plate 5 rotates, the first through hole 501 can be connected with the first hole 401, the second through hole 502 can be connected with the second hole 402, or the second through hole 502 can be connected with the first hole 401, or the first through hole 501 can be connected with the second hole 402. When the second through hole 502 is connected with the first hole 401, the second hole 402 is covered by the regulating plate 5, and when the first through hole 501 is connected with the second hole 402, the first hole 401 is covered by the regulating plate 5.

[0050] Preferably, Figure 1 As shown, the integrated air conditioner also includes a compressor 601 and a four-way valve 602. The outlet of the compressor 601 is connected to the first heat exchanger 1 and the second heat exchanger 2 through the four-way valve 602. Controlling the four-way valve 602 can make one of the first heat exchanger 1 and the second heat exchanger 2 heat, and the other cool.

[0051] The refrigerant is compressed by the compressor 601 and the flow direction of the refrigerant is controlled by the four-way valve 602, thereby controlling the integral air conditioner to be in cooling or heating mode.

[0052] Preferably, Figure 1 As shown, a fresh air fan 603 is provided on the fresh air flow path, and an exhaust air fan 604 is provided on the exhaust air flow path.

[0053] Through the fresh air fan 603 and the exhaust air fan 604, not only the direction of air flow can be controlled, but also the flow rate and flow rate can be adjusted by the size of the fan power.

[0054] To avoid excessive or insufficient indoor pressure, the amount of air entering the room from the fresh air inlet 3011 and the amount of return air discharged from the exhaust outlet 3022 are substantially the same. Specifically, this can be controlled by controlling the fresh air fan 603 and the exhaust air fan 604.

[0055] The fresh air fan 603 is arranged near the fresh air outlet 3012 , and the exhaust air fan 604 is arranged near the exhaust air outlet 3022 .

[0056] The present invention also provides a control method for an air conditioner, wherein the air conditioner is the integrated air conditioner, the integrated air conditioner includes a cooling mode and a heating mode, and the control method includes a cooling method and a heating method. The cooling method is: turning on the integrated air conditioner, so that the first heat exchanger 1 cools and the second heat exchanger 2 heats; the heating method is: turning on the integrated air conditioner, so that the first heat exchanger 1 heats and the second heat exchanger 2 cools.

[0057] Since the fresh air flow path is connected to the fresh air inlet, the fresh air channel 301, the first heat exchanger 1 and the fresh air outlet 3012 in sequence, the fresh air inlet 3011 leads to the outdoors, and the fresh air outlet 3012 leads to the indoors; the cooling method is: turn on the integrated air conditioner to make the first heat exchanger 1 cool and the second heat exchanger 2 heat; the temperature of the fresh air drops when flowing through the first heat exchanger 1, and the air with the dropped temperature enters the room to cool the room; the indoor air is discharged and flows through the second heat exchanger 2, absorbing heat from the second heat exchanger 2, so that the temperature of the refrigerant flowing through the second heat exchanger 2 is lower.

[0058] Since the exhaust air flow path sequentially connects the exhaust air inlet 3021, the return air channel 302, the second heat exchanger 2 and the exhaust air outlet 3022, the heating method is: turn on the integrated air conditioner, so that the first heat exchanger 1 is heated and the second heat exchanger 2 is cooled. When the fresh air flows through the first heat exchanger 1, the temperature rises, and the air with the increased temperature enters the room to heat the room; the indoor air is discharged and flows through the second heat exchanger 2, absorbing cold energy from the second heat exchanger 2, so that the temperature of the refrigerant flowing through the second heat exchanger 2 is higher.

[0059] Preferably, Figure 4-5 As shown, the refrigeration method also includes a second heat exchanger 2 cooling method, and the second heat exchanger 2 cooling method is: controlling the inlet to open, the first outlet 4011 to close, and the second outlet 4021 to open.

[0060] The control adjustment inlet is opened, the first outlet 4011 is closed, and the second outlet 4021 is opened; so that part of the indoor air with lower temperature does not flow through the full heat exchange core 3, but directly flows through the second heat exchanger 2. The actual situation is that this part of the new return air is mixed with the return air flowing through the full heat exchange core 3 and then flows through the second heat exchanger 2, so that the second heat exchanger 2 can release more heat, avoiding the second heat exchanger 2 The condensation temperature is too high and the condensation pressure is too high, thereby improving the heat exchange efficiency of the second heat exchanger 2.

[0061] Preferably, Figure 4-5 As shown, the heating method also includes a second heat exchanger 2 heating method, and the second heat exchanger 2 heating method is: controlling the inlet to open, the first outlet 4011 to close, and the second outlet 4021 to open.

[0062] The control adjustment inlet is opened, the first outlet 4011 is closed, and the second outlet 4021 is opened, so that the indoor air with a higher temperature does not flow through the full heat exchange core 3, but directly flows through the second heat exchanger 2, so that the second heat exchanger 2 can absorb more heat, avoiding the second heat exchanger 2 from freezing and frosting, and improving the heat exchange efficiency of the second heat exchanger 2.

[0063] Preferably, Figure 6-7As shown, the heating method also includes a core heating method, and the core heating method is: controlling and regulating the inlet to be opened, and the first outlet 4011 and the second outlet 4021 are both opened.

[0064] The outdoor temperature is low, and the fresh air entering the full heat exchange core 3 may cause the full heat exchange core 3 to freeze. The control and regulation inlet is opened, and the first outlet 4011 and the second outlet 4021 are both opened. The return air with a higher indoor temperature flows into the fresh air channel 301 through the first outlet 4011, thereby increasing the temperature in the fresh air channel 301, thereby increasing the temperature of the full heat exchange core 3 and preventing the full heat exchange core 3 from freezing. At the same time, part of the return air flows to the second heat exchanger 2 through the second outlet 4021, thereby preventing the second heat exchanger 2 from freezing and frosting, thereby improving the heat exchange efficiency of the second heat exchanger 2, increasing the temperature of the refrigerant flowing to the first heat exchanger 1, and thereby increasing the temperature of the fresh air flowing through the first heat exchanger 1.

[0065] Preferably, Figure 8-9 As shown, the heating method also includes a core preheating method, and the core preheating method is: controlling the inlet to open, the first outlet 4011 to open, and the second outlet 4021 to close.

[0066] Due to the low outdoor temperature, when part of the return air enters the fresh air channel 301 from the first outlet 4011, and part of the return air flows through the second heat exchanger 2 from the second outlet 4021, the full heat exchange core 3 will still freeze and frost, the control adjustment inlet is opened, the first outlet 4011 is opened, and the second outlet 4021 is closed, and the return air with higher indoor temperature flows into the fresh air channel 301 through the first outlet 4011, thereby increasing the temperature of the fresh air entering the full heat exchange core 3, thereby increasing the temperature of the full heat exchange core 3 and avoiding freezing of the full heat exchange core 3.

[0067] The integrated air conditioner is also provided with a temperature sensor, which detects that the outdoor fresh air temperature is not very high, which will not cause the full heat exchange core 3 to freeze, and the temperature of the second heat exchanger 2 can also meet the system requirements, such as Figure 2-3 As shown, the first outlet 4011 and the second outlet 4021 are both closed.

[0068] It is easy for those skilled in the art to understand that, without conflict, the advantageous technical features of the above-mentioned methods can be freely combined and superimposed.

[0069] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention. The above description is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and variations can be made without departing from the technical principles of the present invention. These improvements and variations should also be regarded as the protection scope of the present invention.
