The present invention relates to air conditioning equipment, in particular to a window type ventilation system (A ventilation system of window type) that can realize general ventilation or heat exchange ventilation.

2. Background technology

An air conditioner is a device capable of producing cold/warm air. It is generally installed in the indoor space of a vehicle, office or home, or installed on an indoor wall to cool or heat indoor air. An air conditioner generally has a refrigeration cycle system (cycle) consisting of a compressor, an outdoor heat exchanger, an expansion valve, and an indoor heat exchanger.

Air conditioners are generally divided into the outdoor side (or outdoor unit) installed outdoors and the indoor side (or indoor unit) installed indoors; especially in refrigeration devices, the outdoor side is generally called the heat dissipation side, and the indoor side is called the heat absorption side. ; And an outdoor heat exchanger and a compressor are installed inside the outdoor side, and an indoor heat exchanger is installed inside the indoor side.

As we all know, air conditioners can be roughly divided into split type and integrated type. The outdoor side and indoor side of the split type air conditioner are separated, while the outdoor side and indoor side of the integrated air conditioner are integrated.

Split air conditioners can be divided into wall-mounted and ceiling-embedded types according to their installation forms. Integrated air conditioners are divided into window-type air conditioners and wall-embedded air conditioners. Among them, the window-type air conditioner is centered on the window, and the indoor air conditioner is formed indoors, and the outdoor air conditioner is formed. The outside of the air conditioning room; the wall-mounted air conditioner is installed in the wall outside the window.

The front grille 10 forms the front shell of the integrated air conditioner, which is roughly quadrangular in shape. In addition, the outer ring of the front grille 10 forms an outer edge protruding backward for a certain length, and this structure makes it easier to assemble the front grille 10 on the case 20 and the case cover 30 . The front air inlet 12 is formed at the lower end of the front grille 10, and the front air inlet 12 is a passage for the air in the space requiring air conditioning to flow into the indoor side of the integrated air conditioner. Furthermore, side air inlets 14 are formed on both sides of the front grille 10 , so indoor air can flow into the interior of the integrated air conditioner through the bottom and sides of the front grille 10 . In addition, a long indoor air outlet 16 is formed laterally on the top of the front grille 10 , and the air that completes the heat exchange can be rearranged to the space that needs air conditioning through the indoor air outlet 16 . The inside of the indoor air outlet 16 is formed with exhaust grills (grill) 16a at certain intervals. Not just to one side.

An exhaust door (door) 15 is installed in front of the above-mentioned indoor air outlet 16, and this exhaust door 15 can selectively switch the indoor air outlet 16; Correspondingly, a curved surface is also formed, and the curvature of the curved surface is the same as that of the front grille 10; the exhaust door 15 can slide up and down, so that the indoor air outlet 16 can be selectively switched. If the exhaust door 15 slides downward, the indoor air outlet 16 is exposed outside, so that the air that has completed heat exchange inside the integrated air conditioner can be discharged; if the exhaust door 15 slides upward, the indoor air outlet 16 will be closed, In this way, foreign matter can be prevented from flowing into the interior of the air conditioner from the outside through the indoor air outlet 16 . In addition, a strip-shaped display window (display) 18 is formed horizontally above the indoor air outlet 16. This display window 18 is composed of the following parts. Configuration: The display unit 18a can display the status of the integrated air conditioner according to the command input through the operation unit 18b.

Above the bottom plate 40 is divided into an indoor side and an outdoor side, and various components are mounted on the bottom plate 40 . An air guiding part 41 is formed on the base plate 40, and the air guiding part 41 can not only divide the upper part of the base plate 40 into an indoor side and an outdoor side, but also guide the air flow inside the indoor side.

The air guiding part 41 is connected with an orifice (orifice) 47, and the orifice 47 is a channel for outdoor air to flow to the air guiding part 41, forming the front part of the air guiding part 41, in order to allow the air sucked by the indoor fan to To flow along the inner wall of the air guide member 41 more smoothly, the air guide member 41 and a part of the lower end of the orifice plate 47 are connected together in a form of surface-to-surface contact. The top of the air guiding part 41 forms an exhaust air guiding part 43, and this exhaust air guiding part 43 can guide the air discharged by the indoor fan (not shown) to the indoor air outlet 16 on the front grille 10 top. The exhaust air guide part 43 is assembled on the upper end of the air guide part 41 in a sliding connection, and its structure protrudes from the back to the front by a certain length, and its front end corresponds to the indoor air outlet 16 of the front grille 10 . A control box 44 is installed on the exhaust air guide part 43 , and the control box 44 is located on the upper side and the right side of the exhaust air guide part 47 . That is, the control box 44 is roughly in the shape of "

"shape, it's"

The bent portion of the "shape is installed on the upper right limit of the exhaust air guide part 43.

In addition, a space for installing the capacitor 45 is formed behind the downwardly bent portion of the above-mentioned control box 44 . That is, the capacitor 45 can be installed in the space formed in the control box 44, so it is not necessary to form an additional space for installing the capacitor 45 outside. The inside of the control box 44 is equipped with a main PCB (44a), and this main PCB44a is used to control the action of the integrated air conditioner; The display PCB (not shown in the figure) is connected, therefore, data transmission can be realized between the control box 44 and the display window 18 through the connection line 44b. A control box cover (controlbox cover) 44' for protecting the main PCB (44a) is mounted on the top of the control box 44.

In addition, an indoor heat exchanger 46 is installed in front of the above-mentioned air guide member 41, and the indoor heat exchanger 46 can realize heat exchange between the driving fluid of the heat exchange cycle and the air flowing in from the space requiring air conditioning.

Although not shown in the figure, in fact a fan motor is housed behind the indoor fan, the front end of the fan motor central axis is inserted in the center of the indoor fan, and the rear end is inserted in the center of the outdoor fan 48 described later. Therefore, the fan motor can provide rotational power to the indoor fan and the outdoor fan 48 .

In addition, a shroud 49 is installed behind the air guiding part 41 , and the shroud 49 is at a certain distance from the air guiding part 41 and can guide the air flow inside the outdoor side. An outdoor heat exchanger 50 is installed at the rear end of the bottom plate 40 , that is, at the position behind the shield 49 . The outdoor heat exchanger 50 is capable of exchanging heat between a driving fluid of a heat exchange cycle and air flowing in from the outside.

The function of the integrated air conditioner with the above structure will be described below.

Let's first look at the situation when the integrated air conditioner is driven in cooling mode. First of all, if the integrated air conditioner is powered on, and the user inputs an instruction consistent with the intended use through the operating portion 18b formed on the side of the display window 18, the control box 44 will control each component inside the integrated air conditioner, so that The air conditioner starts.

If the integrated air conditioner starts to drive, the fan motor (not shown) will drive so that the indoor fan (not shown) and outdoor fan (48) connected to the central shaft of the fan motor will rotate. In addition, a compressor (not shown) for compressing refrigerant is also driven to compress the driving fluid into a high-temperature and high-pressure state, thereby starting a heat exchange cycle (cycle).

Driven by the indoor fans installed on the left and right sides as mentioned above, the air in the space that needs to be air-conditioned can flow in through the front air inlet 12 and the side air inlet 14, and the air that flows in flows through the indoor heat exchanger 46 Heat exchange can be achieved during the time, and then flow into the interior of the indoor side. After the air finishes heat exchange in the indoor heat exchanger 46, its temperature will drop relatively, and such air will be sucked toward the front of the indoor fan. Here, the air flows into the indoor fan through a pair of through holes (not shown) formed in the orifice plate 47 .

The air flowing into the indoor fan can be discharged along the circumferential direction of the indoor fan along with the rotation of the indoor fan. The air discharged along the circumferential direction of the indoor fan will flow to the exhaust guide installed on the top of the air guide part 41 under the guidance of the side wall of the air guide part 41 and the left and right partitions (barrier) (barrier) (not shown in the figure). The flow part 43, the air flowing into the air exhaust guide part 43 will flow forward, and then be discharged to the front through the indoor air outlet 16, that is, discharged into the space requiring air conditioning.

Let's take a look at the situation when the above-mentioned integrated air conditioner works in the heating mode. In this case, the functions of the indoor heat exchanger 46 and the outdoor heat exchanger 50 are just reversed, that is, the air flowing through the indoor heat exchanger 46 will exchange heat with the refrigerant and become a relatively high temperature. air before being re-exhausted into the room.

In addition, under the action of a PTC heater (heater) (not shown) installed across the through hole of the orifice plate 47, the air flowing through the through hole of the orifice plate 47 will be further heated, and these heated air It can be exhausted to the indoor air outlet 16 located in front of the air conditioner through the passage as described above. On the other hand, driven by the outdoor fan 48, the outdoor air will be sucked into the inside of the integrated air conditioner, that is, as the outdoor fan 48 rotates, the outside air can pass through the side air inlet 22 of the chassis 20 and the top of the chassis cover 30. The air inlet hole 32 flows into the interior of the integrated air conditioner. The air flowing into the integrated air conditioner will flow along the shroud 49, then be inhaled by the outdoor fan 48, and then be discharged to the rear by the outdoor fan 48. The exhausted air will exchange heat with the driving fluid of the heat exchange cycle (cycle) when flowing through the outdoor heat exchanger 50 . Here, the heat is conducted from the drive fluid to the air, thereby allowing heat to escape from the interior to the exterior.

The air with relatively low temperature flowing to the outdoor side through the above process will reduce the temperature of the compressor. Driven by the outdoor fan 48, the air will flow to the outdoor heat exchanger 50, exchange heat with the driving fluid, and then be discharged outdoors.

However, the conventional all-in-one air conditioner as described above has the following problems.

Because the integrated air conditioner is usually installed on the window, and the main ventilation space needs to be closed during use, it will not be able to achieve effective ventilation in the space that needs to be air-conditioned. In addition, in order to ventilate and purify the air in the space requiring air conditioning more effectively, filters and other components are usually added to the existing integrated air conditioner, which is often limited by the structure of the integrated air conditioner.

In addition, a pipe connected to one side of the integrated air conditioner is installed on one side of the indoor air exhaust port.

The advantage of the window ventilation system of the present invention with the above structure is that it can ventilate the dirty air in the space that needs to be air-conditioned.

In recent years, due to the consideration of energy saving and noise reduction, people's living space is becoming more and more airtight, and the effect of heat insulation is getting better and better. However, in such a confined space, over time, not only the carbon dioxide content in the air will increase, but also the air will be polluted, which will make people feel difficult to breathe. Therefore, the more places where the space is small and there are many people, such as offices and vehicles, the more you should ventilate at any time.

An ideal embodiment of the window ventilation system of the present invention having the above-mentioned structure will be described in detail below with reference to the accompanying drawings.

Fig. 3 is a side view of an embodiment of the ventilation device of the present invention, as shown in the figure, the window type ventilation system of the present invention includes the following components: an integrated air conditioner, which can suck air and make the air realize heat exchange inside, Then the air that has completed the heat exchange is discharged; the ventilator 200 is installed on the top of the integrated air conditioner and is detachable, and it can ventilate the air in the space that needs air conditioning.

The integrated air conditioner has the same structure and function as the existing integrated air conditioner, so it will be briefly explained here. A one-piece air conditioner is roughly hexahedral in shape and its casing consists of the front grille forming the front casing, the cabinet forming the side and rear casings, and the cabinet cover (not shown) forming the upper casing . The front grille forms the front shell of the integrated air conditioner. It is roughly quadrangular in shape. The central part of the front protrudes forward to a certain height, and the protruding height becomes smaller as it goes to the upper and lower ends, so it is arc-shaped when viewed from the side. In addition, the outer ring of the front grille forms an outer edge protruding backward for a certain length, and this structure can make it easier to assemble the front grille to the chassis and the chassis cover. The front air inlet is formed at the lower end of the front grille, and this front air inlet is the channel through which the air in the space requiring air conditioning flows into the indoor side of the integrated air conditioner. Furthermore, side air intakes are formed on both sides of the front grille. Therefore, indoor air can flow into the interior of the integrated air conditioner through the underside and sides of the front grille. A long indoor air outlet (not shown in the figure) is formed horizontally on the upper part of the front grille, through which the air after heat exchange can be rearranged to the space requiring air conditioning. The front of the indoor air outlet is equipped with an exhaust door, which can selectively switch the indoor air outlet. The exhaust door is roughly quadrangular, corresponding to the shape of the front grille, and also forms a curved surface, and the curvature of the curved surface is the same as that of the front grille. The exhaust door can slide up and down, so that the indoor air outlet can be selectively opened and closed. Also, behind the front grille is mounted the chassis, which forms the side and rear enclosures of the integrated air conditioner. The chassis can cover various components installed inside the integrated air conditioner, and an air flow channel is formed inside it.

In order to allow outdoor air to flow smoothly into the interior of the outdoor side, several side air inlet holes are formed on the rear half of the sides of the chassis. A rear exhaust hole (not shown in the figure) for exhausting air is formed on the rear of the chassis. The rear exhaust vents are larger than the side intake vents and are evenly spaced across the entire rear panel of the case. In addition, the side surfaces on both sides of the chassis and the upper end of the back form a stepped structure, which facilitates the connection between the chassis and the chassis cover forming the upper shell of the integrated air conditioner. The casing cover is roughly quadrangular, and it can be used as a loam cake of a simple integrated air conditioner on the one hand, and can also be used as an loam cake of an integrated air conditioner equipped with a ventilator 200 described later on the other hand. An exhaust air guide part is formed at the inner upper end of the integrated air conditioner enclosed by the case. Although it is not shown in the figure, in fact the air exhaust guide part can play the following role, that is, it can guide the air discharged by the indoor fan of the integrated air conditioner to flow to the indoor air exhaust port on the upper part of the front grille.

A control box is installed on the right side of the top of the above-mentioned exhaust air guiding part. The rear end of the control box is first bent downwards, and then bent back again to form a stepped structure. The rear of the control box with a stepped structure forms an installation guide, which is used for installing the ventilator 200 described later. In addition, although it is not shown in the figure, in fact the main PCB is installed inside the control box, and this main PCB is used to control the action of the integrated air conditioner. One side of the control box is equipped with a connection line, and this connection line is also connected to the display PCB (not shown in the figure), so the data transmission between the control box and the display part (not shown in the figure) can be realized through this connection line .

An outdoor heat exchanger is installed behind the above-mentioned control box. The outdoor heat exchanger is capable of exchanging heat between a driving fluid of a heat exchange cycle and air flowing in from the outside.

A ventilation device 200 is installed on the installation guide of the above-mentioned integrated air conditioner, and the ventilation device 200 is used for ventilation treatment of the air in the space requiring air conditioning. The ventilation device 200 will be described in more detail below.

Fig. 4 is a sketch map of the planar structure of an embodiment of the ventilation device of the present invention. As shown in the figure, the ventilation device 200 of the present invention includes the following components: a fan 210, which can suck in external air by rotation; 210 provides driving force to rotate the fan 210; the filter part can purify the air sucked by the fan 210;

The above-mentioned fan 210 and motor 220 are installed on the left side of the ventilation device 200 (in FIG. 3 ). The motor 220 is a cylindrical DC motor with a cylindrical appearance. The center of the motor 220 is equipped with a rotating shaft 222 that runs through the front and back. The rear end of the rotating shaft 222 is equipped with a fan 210 . The fan 210 can rotate under the action of the rotational power transmitted by the motor 220 , and discharges the air flowing in through the outdoor air inlet 242 or the indoor air inlet 248 of the air guiding duct part 240 described later to the indoor air outlet 260 . In addition, opposite to the fan 210 and the motor 220, that is, on the right side of the ventilator 200 (in FIG. 3 ), a guide duct portion 240 is formed, and a switching louver 244 is housed inside the guide duct portion 240, so that the intake air can be guided. flow direction.

The above-mentioned guide duct part 240 is roughly rectangular, and a certain space is formed inside, one side is connected with the filter part, and the other side forms an outdoor air inlet 242 for allowing outdoor air to flow in. One of the filter parts, i.e. the air filter 232, is installed at the outdoor air inlet 242, and this air filter 232 can filter relatively large dust that flows into the air from the outside. The air filter 232 is generally made of a relatively large mesh, and sometimes other materials with antibacterial functions are added on the surface of the mesh.

The above-mentioned outdoor air inlet 242 is installed on the outside of the window together with a part of the integrated air conditioner box, and acts as an inlet, that is, outside air can flow into the inside of the ventilation device 200 through it.

A switching louver 244 is installed inside the above-mentioned guide duct portion 240 , and the flow direction of the air sucked by the fan 210 can be changed by using the switching louver 244 . The switching louvers 244 are basically installed along the diagonal of the diversion duct part 240, and the top of the diversion duct part 240 forms a louver handle 246, which is connected to the switching louvers 244, and can be used to control the switching louvers 244 very conveniently.

When it is necessary to inhale outside air from the outdoor air inlet 242 to ventilate the indoor air, as long as the shutter handle 246 is used to switch the switching louvers 244 to the side of the outdoor air inlet 242, the outdoor air can flow into the room. When it is necessary to inhale indoor air from the indoor air inlet 248 described later, so as to ventilate the indoor air, just use the louver handle 246 to switch the switching louvers 244 in the direction of the arrow shown in FIG. upward, the indoor air can be made to flow into the indoor air inlet 248.

An indoor air inlet 248 is formed on the front of the air guide duct portion 240 (in FIG. 3 ) to allow indoor air to flow in. The underside of the guide pipe part 240 forming the indoor air inlet 248 has the following shape, that is, it is bent backward from the bottom of the indoor air inlet 248 first, and then bent downward from the middle part. This shape coincides with the shape of the installation guide part of the integrated air conditioner, which is very convenient for the installation of the ventilation device 200 .

In the above embodiments, the ventilation device 200 is assembled with the integrated air conditioner, and they can be covered by the integrated air conditioner case cover (not shown in the figure). However, this structure may not be used, for example, another assembly material (kit) may be used to install the ventilation device 200 on the top of the case cover of the integrated air conditioner.

Fig. 5 is a schematic cross-sectional view of the ventilating device in an ideal embodiment of the present invention, showing the state when the general ventilating and heat exchanging ventilating are started. As shown in the figure, the indoor air outlet 260 is equipped with an indoor air outlet louver 262, and the indoor air outlet louver 262 can selectively switch the indoor air outlet 260, so that the indoor air outlet 260 can be discharged to the indoor air outlet. 260 clean air is converted to general ventilation mode or heat exchange ventilation mode.

The outer frame of the above-mentioned indoor air outlet louver 262 is the same shape as the indoor air outlet 260, it can be installed by inserting its outer frame into the indoor air outlet 260, and the center of its lower end is connected with one end of the handle 270 . The lower end of the indoor air outlet louver 262 is equipped with a handle 270, which not only can switch the indoor air outlet louver 262, but also can switch the pipeline louver 282 described later. One end of the handle 270 is connected to the indoor air outlet louver 262 , and the other end is connected to the duct louver 282 ; wherein the duct louver 282 can switch the duct 280 leading to the heat exchanger 110 of the integrated air conditioner 100 . The duct louver 282 is formed at the entrance of the duct 280, and it is connected to the lower end of the handle 270, that is, one end of the handle 270 is connected to the lower end of the indoor air exhaust louver 262, and the other end is bent downward and extended, and the last end is connected to the duct. The louvers 282 are connected. If the handle 270 is turned to the left or right, the louver 262 of the indoor air outlet will also move to the left or right accordingly, so that the indoor air outlet 260 is opened or closed. Correspondingly, the opening or closing state of the duct louver 282 is just opposite to the opening and closing state of the indoor air outlet louver 262 . That is, when it is required to work in a general ventilation mode, the louvers 262 of the indoor air outlet can be opened, so that the air that has been ventilated in the ventilation device 200 can be exhausted into the room through the indoor air outlet 260 . When it is necessary to work in the way of heat exchange and ventilation, the indoor air outlet louvers 262 can be closed, so that the air that has been ventilated in the ventilation device 200 can flow through the heat exchanger 110 of the integrated air conditioner 100, and then close to the indoor air conditioner. The state of temperature is discharged to the room.

An outdoor air inlet 242 is formed on one side of the guide duct part 240, and a filter part is installed on the other side. The filter portion is preferably made of a HEPA filter 234, because the fine dust that cannot be filtered out by the air filter 232 installed at the outdoor air inlet 242 will be filtered out after the secondary filtration of the HEPA filter 234. This is because the HEPA filter 234 is a high-performance filter coated with tannin components of green tea having an antibacterial effect, and its filtering effect on fine dust of 0.3 μm is as high as 99.7%. In addition, although not shown in the figure, in fact, a deodorizing filter capable of filtering odor particles in the air may be installed on the side of the HEPA filter 234 . The deodorizing filter mainly uses a super activated carbon filter, which can remove the smell of smoke and food in the air.

In addition, an indoor air outlet 260 is formed above the fan 210 , and the air flowing in from the outdoor air inlet 242 or the indoor air inlet 248 can be exhausted indoors through the indoor air outlet 260 . The dirty air flowing in through the outdoor air inlet 242 or the indoor air inlet 248 under the suction force of the fan 210 will flow through the filter part, that is, flow through the air filter 232, the HEPA filter 234 and the deodorizing filter and be filtered, and then The purified air can be exhausted to the space requiring air conditioning through the above-mentioned indoor air outlet 260 .

Let's take a look at the function of the ventilation device 200 with the above structure. If the user chooses the ventilation mode, the ventilation device 200 is required to inhale external air, so as to perform ventilation treatment for the air in the space requiring air conditioning. In this case, the user can use the louver handle 246 to turn the switching louver 244 to face the outdoor air inlet 242 , and then turn on (ON) a power switch (not shown) installed on the ventilation device 200 .

If the ventilator 200 is powered on, the motor 220 will start to rotate, and under the action of the rotating force generated by the motor 220, the fan 210 connected to one end of the rotating shaft 222 of the motor 220 will also rotate, thereby generating suction force. As the fan 210 rotates, external air will flow into the air guiding duct portion 240 through the outdoor air inlet 242 .

When external air flows in, the air filter 232 installed at the outdoor air inlet 242 can perform preliminary filtration on the air, and filter out relatively large dust in the air. The air flowing into the guide duct part 240 will flow into the open side space of the guide duct part 240 under the guiding effect of the switching louvers 244, and then the air will flow through the filter part.

The above-mentioned filter part, that is, the HEPA filter 234 and the deodorizing filter can filter out the fine dust and peculiar smell that cannot be filtered out by the air filter 232 at the outdoor air inlet 242 . Foreign matter such as fine dust in the air is filtered out by the filter unit, and it becomes clean air. The clean air flows to the fan 210, and under the action of the rotation force of the fan 210, it is exhausted into the room (space requiring air conditioning) through the indoor air outlet 260 formed above the fan 210. On the other hand, when the indoor air needs to be sucked in, the dirty air is ventilated, and then discharged to the room again, the user can use the louver handle 246 to adjust the switching louvers 244 so that it faces the indoor air inlet 248 (in FIG. dotted line position). In this way, the dirty air flowing to the indoor air inlet 248 will flow through the guide duct part 240 under the action of the rotation force of the fan 210, and then flow through the filter part and be purified. The air purified by the filter part can be exhausted indoors again through the indoor air outlet 260 . In addition, when it is necessary to use the ventilation device 200 to ventilate the outdoor air or indoor air, and to discharge the ventilated air at a state close to the indoor temperature, as shown in FIG. The outflowing clean air flows through the heat exchanger 110 of the integrated air conditioner 100 and then is exhausted into the room. That is, if the handle 270 is moved to close the indoor air outlet louvers 262, the duct louvers 282 will be opened, and the air flowing in through the outdoor air inlet 242 or the indoor air inlet 248 will flow through the filter part and be purified. The purified air can flow through the heat exchanger 110 of the integrated air conditioner 100 through the pipe 280 at the lower end of the indoor air outlet 260 , and the temperature of the air will be adjusted during this process. Then, the temperature-conditioned air will flow to the air guiding part 135 under the rotating force of the indoor turbo fan 130 installed in the integrated air conditioner 100, and finally be discharged into the room.

The scope of the present invention as described above is not limited to the above-mentioned embodiments, and for those of ordinary skill in the industry, it is possible to make various modifications on the basis of the present invention within the technical scope as described above. of.

The beneficial effects of the present invention are: in the window type ventilation system of the present invention, the ventilation device includes the following components: fan, motor, filter part capable of purifying air, switching louvers for changing the direction of air flow, and indoor air outlet Louvres, duct louvers; the ventilation device with this structure is installed on the top of the integrated air conditioner and is detachable. In addition, in order to discharge the air purified by the ventilation device at a state close to the indoor temperature, a pipe is installed between the ventilation device and the integrated air conditioner, so that the air discharged from the ventilation device can flow through the integrated air conditioner through the pipe. The heat exchanger of the type air conditioner, after the temperature is adjusted, the air will be discharged into the room. In order to cool/heat a space that requires air conditioning, an integrated air conditioner can be installed and the space needs to be sealed. On this basis, if the present invention is adopted, outdoor air can be inhaled through a ventilating device with a simple structure, so that the existing airtight space only equipped with an integrated air conditioner can be ventilated. That is, it is not necessary to purchase an air cleaner separately, so that the economical burden on the user can be reduced. Furthermore, when the temperature difference between indoor and outdoor is very large, it is also possible not to inhale outdoor air. At this time, the direction of the switching louvers of the ventilator can be changed so that the ventilator only inhales indoor air. Dirty air in the air-conditioned space is sucked in, purified and then re-emitted into the room, thus increasing the thermal efficiency of existing integrated air conditioners in this way.

In addition, in order to make the air that has been ventilated in the ventilating device discharged into the room close to the indoor temperature, there is also a pipeline between the ventilating device and the integrated air conditioner. That is, when the air flows through the pipeline, the temperature will be regulated by the heat exchanger of the integrated air conditioner, and then the purified, ventilated and temperature-regulated air can be discharged into the room through the integrated air conditioner, so the present invention can Create a more comfortable environment for users.

The above are only preferred embodiments of the present invention, and are not intended to limit the present invention in any form. Any simple modifications, equivalent changes and modifications made to the above embodiments according to the technical essence of the present invention still belong to within the scope of the technical solutions of the present invention.
