Detailed Description

The principles and features of the present utility model are described below with reference to the drawings, the examples are illustrated for the purpose of illustrating the utility model and are not to be construed as limiting the scope of the utility model.

With the increasing concern of ozone layer destruction and greenhouse gas problems at home and abroad, the development of new refrigerants is quickened in all countries of the world in order to solve the climate threat caused by the continuous increase of market demands. The research of new refrigerants is divided into two directions, one is new synthetic working medium, the other is natural working medium, and carbon dioxide is one of natural working medium.

In the field of conventional kitchen air conditioners, most of the conventional refrigerants are used, and the conventional kitchen air conditioners have various structural forms, but are most accepted by users as an integrated machine (namely, an integrated air conditioner). Under the requirement, the higher requirement is required to be put forward on the structural design of the kitchen air conditioner, the size is miniaturized as much as possible under the condition of meeting the performance requirement, the kitchen air conditioner can be installed in a suspended ceiling of a kitchen as much as possible, the invisible installation is realized, the refrigerating performance can meet the kitchen requirement, and the appearance is attractive.

Carbon dioxide is a high-efficiency refrigerant, a vapor compression cavity of the high-pressure refrigerant is in a high-pressure working condition, and the unit refrigerating capacity is large, so that the high-efficiency refrigerant is suitable for kitchen air conditioning working conditions. However, since the conventional kitchen does not have an external machine location, duct ventilation is generally used. For the carbon dioxide air conditioner, the refrigerating capacity is large, but the size of the heat exchanger is also large, so that the resistance on the outer side of the heat exchanger is large, and the air quantity required for completing heat exchange is also large. Under the restriction of structure, heat exchange and noise, the design of the air supply and exhaust structure form plays a vital role in the performance of the whole air conditioning system.

The embodiment of the utility model provides an integrated air conditioner which can be used as a kitchen air conditioner, and can be installed in a kitchen suspended ceiling or at other positions of a kitchen when being used as the kitchen air conditioner. Of course, the integrated air conditioner provided by the embodiment of the utility model can be also used for other spaces other than a kitchen, such as a bathroom, and also can be installed in a suspended ceiling of the bathroom.

The following detailed description refers to the accompanying drawings.

As shown in fig. 1, an embodiment of the present utility model provides an integrated air conditioner 100, which may be a carbon dioxide integrated air conditioner 100, including: the heat exchange device comprises a shell 1, a first heat exchange module and a second heat exchange module.

As shown in fig. 1, a first heat exchange chamber 15 and a second heat exchange chamber 16 are provided in the housing 1 so as to be spaced apart from each other in a horizontal direction. The first heat exchange module comprises an indoor side heat exchanger 21 and an indoor side fan 22 which are arranged in the first heat exchange cavity 15. The second heat exchange module includes an outdoor side heat exchanger 31 and an outdoor side fan 32 disposed in the second heat exchange chamber 16.

Of course, the integrated air conditioner 100 further includes a compressor 4, a throttle mechanism, a control board 5, and the like. The compressor 4, the indoor heat exchanger 21, the throttle mechanism, and the outdoor heat exchanger 31 are connected by refrigerant pipes, and can form refrigerant circulation for realizing an air temperature adjusting function.

Wherein the indoor side fan 22 and/or the outdoor side fan 32 are provided as an axial flow fan 7, the axial flow fan 7 includes a driving motor 71 and a plurality of driving impellers 72 arranged in a stacked manner in an axial direction of the axial flow fan 7, and the driving motor 71 is connected to the plurality of driving impellers 72 to drive the driving impellers 72 to rotate.

The embodiment of the utility model provides an integrated air conditioner 100, which comprises a casing 1, a first heat exchange module and a second heat exchanger module. A first heat exchange cavity 15 and a second heat exchange cavity 16 are arranged in the shell 1. The first heat exchange module is arranged in the first heat exchange cavity 15, and comprises an indoor side heat exchanger 21 and an indoor side fan 22. The indoor side fan 22 is used for driving airflow to flow through the first heat exchange cavity 15, exchanges heat with the indoor side heat exchanger 21 and then is discharged to the indoor space, and plays a role in regulating the indoor air temperature. The second heat exchange module is disposed in the second heat exchange chamber 16, and the second heat exchange module includes an outdoor side heat exchanger 31 and an outdoor side fan 32. The outdoor fan 32 is used for driving the airflow to flow through the second heat exchange cavity 16, exchange heat with the outdoor heat exchanger 31 and then discharge the airflow to the outdoor space.

Since the first heat exchange chamber 15 and the second heat exchange chamber 16 are separated from each other, the heat exchange efficiency of the indoor side heat exchanger 21 can be prevented from being lowered due to the mutual influence of the airflows in the first heat exchange chamber 15 and the second heat exchange chamber 16. The first heat exchange cavity 15 and the second heat exchange cavity 16 are mutually separated along the horizontal direction, and then the first heat exchange module and the second heat exchange module are also arranged at intervals along the horizontal direction, compared with the scheme of stacking arrangement along the vertical direction, the scheme is favorable for reducing the height of the integrated air conditioner 100, is convenient for installing the integrated air conditioner 100 in a kitchen ceiling, does not additionally occupy precious space in a kitchen, and is favorable for popularization and application of the kitchen air conditioner.

The indoor-side fan 22 may be provided as the axial-flow fan 7, the outdoor-side fan 32 may be provided as the axial-flow fan 7, and both the indoor-side fan 22 and the outdoor-side fan 32 may be provided as the axial-flow fan 7. The axial flow fan 7 is provided with a plurality of drive impellers 72 arranged in a stacked manner in the axial direction, which corresponds to the multistage axial flow fan 7. Therefore, compared with the conventional integrated air conditioner 100 which mostly adopts a centrifugal fan (if the flow is increased, the size of the centrifugal fan must be increased), the multi-stage axial flow fan 7 is adopted in the scheme, which is favorable for increasing the air quantity, has smaller size, and can meet the air quantity requirement of the high-resistance heat exchanger.

In one exemplary embodiment, the number of drive impellers 72 is two, as shown in FIG. 3.

Thus, the axial flow fan 7 is a two-stage axial flow fan 7, which can generate relatively large air quantity and also make the size of the axial flow fan 7 relatively small.

In an exemplary embodiment, the central axis of the axial flow fan 7 extends in the width direction of the casing 1, which is advantageous in reducing the size of the casing 1 in the width direction.

In an exemplary embodiment, the axial flow fan 7 further includes: as shown in fig. 2 and 3, the housing 73 is fixed to the housing 73, and the drive motor 71 and the drive impeller 72 are housed in the housing 73.

A mounting bracket 734 may be disposed within the housing 73, and the drive motor 71 is supported and secured to the mounting bracket 734 as shown in fig. 2.

The housing 73 may be cylindrical, rounded rectangular, or other shapes.

In an exemplary embodiment, the housing 73 is provided with a locking portion 731, and as shown in fig. 2, the locking portion 731 is locked with the casing 1.

The clamping part 731 is arranged on the outer cover 73, and the clamping part 731 is clamped with the machine shell 1, so that the positioning and the limiting of the axial flow fan 7 and the machine shell 1 can be realized, the mounting difficulty of the axial flow fan 7 can be reduced, and the assembly efficiency of the axial flow fan 7 and the machine shell 1 can be improved.

Wherein, the clamping portion 731 may include, but is not limited to: a hook, a clamping groove, a buckle and the like. Correspondingly, the casing 1 is correspondingly provided with a clamping and matching part, and the clamping and matching part can include but is not limited to: a clamping groove, a clamping hook, a clamping buckle and the like. The clamping fit portion may be disposed on a side wall of the casing 1, or may be disposed on a top wall and/or a bottom wall of the casing 1.

The number of the clamping portions 731 may be plural, as shown in fig. 2, and the plurality of clamping portions 731 are disposed at intervals along the circumferential direction of the outer cover 73, which is beneficial to improving positioning reliability.

In an exemplary embodiment, the housing 73 is provided with a securing portion 732, as shown in FIG. 2. The fixing portion 732 is fixedly connected to the casing 1 by a fastener.

The fixing part 732 is arranged on the outer cover 73, and the axial flow fan 7 can be fixedly connected with the casing 1 through a fastener (such as a screw, a bolt and the like) by utilizing the matching of the fixing part 732 and the casing 1, so that the fixing reliability of the axial flow fan 7 is ensured, and the reduction of fan vibration and vibration noise is facilitated.

Wherein the fixing part 732 may include, but is not limited to: the hole or the connecting protrusion with the hole can be a through hole or a blind hole, and the hole can be a smooth hole or a threaded hole. Accordingly, the casing 1 is correspondingly provided with a fixed matching part, and the fixed matching part may include, but is not limited to: the hole or the connecting protrusion with the hole can be a through hole or a blind hole, and the hole can be a smooth hole or a threaded hole.

The fixed fitting may be provided on a side wall of the casing 1 or may be provided on a top wall and/or a bottom wall of the casing 1.

The number of the fixing portions 732 may be plural, and as shown in fig. 2, the plurality of fixing portions 732 are disposed at intervals along the circumferential direction of the outer cover 73, which is advantageous for improving fixing reliability.

In an exemplary embodiment, the number of drive motors 71 is equal to and in one-to-one correspondence with the number of drive impellers 72, as shown in fig. 3.

Alternatively, the number of drive motors 71 is smaller than the number of drive impellers 72, at least one drive motor 71 being connected to at least two drive impellers 72.

In other words, one drive motor 71 drives one drive impeller 72, as shown in fig. 3, which is advantageous in reducing the power requirements for a single drive motor 71. In addition, it is convenient to realize different air supply and exhaust modes by matching the plurality of driving motors 71 (the rotation speed and the rotation direction can be the same or different).

Alternatively, one driving motor 71 may drive a plurality of driving impellers 72, which is advantageous in reducing the number of driving motors 71 and simplifying the structure of the axial flow fan 7. One drive motor 71 may drive all of the drive impellers 72; alternatively, the partial drive motor 71 may drive at least two drive impellers 72, and the partial drive motor 71 may drive only one drive impeller 72.

In an exemplary embodiment, the housing 73 is provided with a wire passing slot 733, and as shown in fig. 2, the power wire 74 of the axial flow fan 7 is wound out through the wire passing slot 733.

In an exemplary embodiment, a compressor chamber 17 is further provided in the casing 1, and the first heat exchange chamber 15, the compressor chamber 17 and the second heat exchange chamber 16 are sequentially disposed in a horizontal direction and are spaced apart from each other, and the compressor 4 is provided in the compressor chamber 17.

This is advantageous in further reducing the height of the integrated air conditioner 100, facilitating installation of the integrated air conditioner 100 in a kitchen ceiling.

In addition, the compressor 4 is independently arranged in the compressor cavity 17, so that vibration generated during the operation of the compressor 4 can be prevented from being transmitted to the indoor space through the first heat exchange cavity 15 or the second heat exchange cavity 16, and the working noise of the integrated air conditioner 100 can be reduced.

Wherein the compressor 4 can be locked to the housing 1 by means of bolts. The compressor chamber 17 may be separated from the first heat exchange chamber 15 by a first partition 18, and the compressor chamber 17 may be separated from the second heat exchange chamber 16 by a second partition 19.

In other embodiments, the compressor 4 may also be disposed within the second heat exchange chamber 16.

In an exemplary embodiment, the compressor 4 is a carbon dioxide compressor.

The compressor 4 is a carbon dioxide compressor, and the refrigerant used in the integrated air conditioner 100 is carbon dioxide. The refrigerant adopts carbon dioxide, is nontoxic and nonflammable, is harmless to the atmosphere, is environmentally friendly, and has ODP (ozone depletion potential value) =0 and gwp (global warming potential value) =1.

The temperature and pressure of the refrigerant output from the outdoor heat exchanger 31 of the carbon dioxide air conditioner are relatively high. By adopting the multistage axial flow fan 7, the outdoor side heat exchanger 31 is beneficial to efficiently radiating and the indoor side heat exchange is beneficial to efficiently exchanging heat, thereby being beneficial to improving the heat exchange efficiency of the indoor side heat exchanger 21 and improving the energy efficiency of the system.

In an exemplary embodiment, the compressor 4 is of a vertical construction, and the compressor 4 is erected in the compressor chamber 17 in the height direction of the casing 1.

This facilitates the full use of the space in the height direction of the casing 1, and facilitates the reduction of the dimension in the width direction of the casing 1, thereby facilitating the further reduction of the volume of the integrated air conditioner 100.

In an exemplary embodiment, the outdoor-side heat exchanger 31 and the outdoor-side fan 32 are disposed in this order along the gas flow direction in the second heat exchange chamber 16, that is: the outdoor fan 32 is located on the downstream side of the outdoor heat exchanger 31. The outdoor side fan 32 is provided with a temperature resistant structure so that the outdoor side fan 32 can withstand a temperature of 70 ℃ or higher.

In one exemplary embodiment, the integrated air conditioner 100 is provided with a cooling mechanism for cooling the outdoor side fan 32.

For kitchen air conditioning, the operation is mainly in a cooling mode. When the integrated air conditioner 100 is operated in cooling mode, the outdoor side heat exchanger 31 is a condenser, and heat is radiated to the outside, resulting in a higher temperature of the air flowing to the outdoor side fan 32. Especially when the refrigerant is carbon dioxide, the temperature of the refrigerant discharged from the outdoor heat exchanger 31 is higher, which causes the temperature of the vicinity to rise to 70 ℃.

Therefore, the outdoor-side fan 32 may be provided with a temperature resistant structure, so that the components (the housing 73, the driving motor 71, the driving impeller 72, etc.) of the outdoor-side fan 32 may withstand temperatures above 70 ℃ to ensure that the outdoor-side fan 32 may reliably operate for a long period of time. Wherein the temperature resistant structure may include, but is not limited to: the temperature-resistant coating is arranged on the surface of the outdoor side fan 32, and can bear the temperature of more than 70 ℃, and is supported by the temperature-resistant material. Alternatively, the outdoor-side fan 32 is directly made of a temperature-resistant material. The temperature resistant material may withstand temperatures above 70 ℃, and the temperature resistant material may include, but is not limited to: temperature resistant engineering plastics, metals, and the like. Such as the housing 73, the driving impeller 72, and the driving motor 71, can be made of metal or engineering plastics such as PA (nylon), POM (polyoxymethylene), PBT (polybutylene terephthalate), PC (polycarbonate), and PPO (polyphenylene oxide).

A cooling mechanism may be added to the integrated air conditioner 100 to cool the outdoor fan 32, so as to reduce adverse effects of high-temperature gas near the outdoor heat exchanger 31 on the outdoor fan 32, and ensure that the outdoor fan 32 can reliably operate for a long time. Wherein the cooling mechanism may include, but is not limited to: a cold air inlet is additionally arranged on the casing 1, so that cold air outside/inside is introduced into the second heat exchange cavity 16 and flows to the outdoor heat exchanger 31, and thus high-temperature air flow flowing through the outdoor heat exchanger and low-temperature air flow introduced by the cold air inlet can be mutually neutralized, so that the temperature of the air flow finally flowing through the outdoor heat exchanger 31 is not excessively high. Alternatively, the outdoor-side fan 32 may be cooled by one or a combination of a plurality of air cooling means, liquid cooling means, oil cooling means, and the like.

As for the indoor side heat exchanger 21, which is generally used as an evaporator, the ambient temperature is relatively low, so that the indoor side fan 22 may not need to be additionally designed for temperature resistance and/or cooling as with the outdoor side fan 32.

In an exemplary embodiment, as shown in fig. 1, the indoor-side heat exchanger 21 is disposed at a horizontal interval from the indoor-side fan 22, and the outdoor-side heat exchanger 31 is disposed at a horizontal interval from the outdoor-side fan 32.

Compared with the scheme that the indoor side heat exchanger 21 and the indoor side fan 22 are stacked in the vertical direction, or the outdoor side heat exchanger 31 and the outdoor side fan 32 are stacked in the vertical direction, or the indoor side heat exchanger 21 and the indoor side fan 22 are stacked in the vertical direction, and the outdoor side heat exchanger 31 and the outdoor side fan 32 are stacked in the vertical direction, the scheme is favorable for reducing the dimension of the integrated air conditioner 100 in the height direction, and further is favorable for installing the integrated air conditioner 100 in a kitchen ceiling, and is favorable for popularization and application of the kitchen air conditioner.

In an exemplary embodiment, as shown in fig. 1, the indoor-side heat exchanger 21 includes a first heat exchanging portion 211 and a second heat exchanging portion 212 connected to each other. The first heat exchanging portion 211 and the indoor-side fan 22 are disposed at intervals along the longitudinal direction of the casing 1, and the second heat exchanging portion 212 and the indoor-side fan 22 are disposed at intervals along the width direction of the casing 1.

In other words, the first heat exchanging portion 211 and the second heat exchanging portion 212 are bent in the circumferential direction of the casing 1 to form an L-shaped structure. This is advantageous in increasing the heat exchange area of the indoor side heat exchanger 21, and thus in improving the heat exchange efficiency of the indoor side heat exchanger 21.

In an exemplary embodiment, the outdoor-side heat exchanger 31 and the outdoor-side fan 32 are disposed at intervals in the width direction of the cabinet 1, as shown in fig. 1.

In other words, the outdoor heat exchanger 31 is in a flat plate structure, and can be relatively thick to improve the heat exchange capability of the outdoor heat exchanger 31, and to reduce the size of the casing 1 in the length direction.

In one embodiment, the number of heat exchange tube rows of the indoor side heat exchanger 21 is smaller than the number of heat exchange tube rows of the outdoor side heat exchanger 31. Such as: the indoor side heat exchanger 21 includes 2 rows of heat exchange tubes. The outdoor side heat exchanger 31 includes 7 rows of heat exchange tubes.

In one embodiment, the control board 5 is disposed within the second heat exchange chamber 16 and is located at an end of the second heat exchange chamber 16 remote from the first heat exchange chamber 15. This allows the control plate 5 to be cooled by the air flow in the second heat exchange chamber 16.

In an exemplary embodiment, the casing 1 is provided with a first air inlet corresponding to the first heat exchanging part 211 and the second heat exchanging part 212, and the casing 1 is provided with a first air outlet corresponding to the air outlet of the indoor side fan 22. The casing 1 is provided with a second air inlet corresponding to the second heat exchanger, and the casing 1 is provided with a second air outlet corresponding to the air outlet of the outdoor fan 32.

In one exemplary embodiment, the integrated air conditioner further includes a water-taking mechanism and a water-receiving tray 63, as shown in fig. 1. The water-fetching means is at least partly located in the second heat exchange chamber 16. The water pumping mechanism may be located entirely within the second heat exchange chamber 16 or may be located partially within the second heat exchange chamber 16, such as by having only the water pumping impeller 62 located within the second heat exchange chamber 16. The water receiving tray 63 is located below the indoor side heat exchanger 21 and the outdoor side heat exchanger 31, and is provided to collect condensed water dropped from the indoor side heat exchanger 21. The water receiving tray 63 may be inclined downward in a direction from the indoor side heat exchanger 21 to the outdoor side heat exchanger 31 so that condensed water can flow under the force of gravity to be concentrated under the outdoor side heat exchanger 31. Thus, a portion of the drip tray 63 is located within the first heat exchange chamber 15 and a portion is located within the second heat exchange chamber 16. The water-pumping mechanism is provided to pump condensed water in the water pan 63 to the outdoor-side heat exchanger 31 to liquid-cool the outdoor-side heat exchanger 31.

In this way, the condensed water in the first heat exchange cavity 15 and the second heat exchange cavity 16 can be collected, and the condensed water can be utilized to cool the outdoor side heat exchanger 31. In this way, the outdoor heat exchanger 31 can be cooled by the outdoor fan 32 and the water-taking mechanism, which is beneficial to the efficient heat dissipation of the outdoor heat exchanger 31.

When the compressor 4 adopts the carbon dioxide compressor 4 and the whole machine is in refrigeration operation, the temperature and the pressure of the refrigerant discharged by the outdoor side heat exchanger 31 are both higher, so that the temperature and the pressure of the system are higher. This scheme carries out dual cooling through outdoor side fan 32 and mechanism of fetching water, is favorable to outdoor side heat exchanger 31 high-efficient heat dissipation, and then is favorable to reducing system temperature and pressure, is favorable to improving the reliability of system operation.

In an exemplary embodiment, as shown in fig. 1, the water pumping mechanism includes a water pumping motor 61 and a water pumping impeller 62 connected to the water pumping motor 61, and a water pumping gap is provided in the outdoor side heat exchanger 31, and the water pumping impeller 62 is at least partially located in the water pumping gap.

In this way, on the one hand, the condensed water is whipped to the inside of the outdoor side heat exchanger 31 by the water-whipping impeller 62, so that more heat exchanging parts of the outdoor side heat exchanger 31 are contacted with the condensed water, thereby being beneficial to improving the heat dissipation efficiency of the outdoor side heat exchanger 31.

On the other hand, this allows the water impeller 62 to be at least partially hidden inside the outdoor-side heat exchanger 31, thereby contributing to further reduction in the volume of the integrated air conditioner 100.

In one embodiment, the outdoor side heat exchanger 31 includes 7 rows of heat exchangers in a 6+1 configuration, that is: wherein 6 rows of heat exchange tubes are adjacent together in sequence, and a water gap is formed between the 7 th row of heat exchange tubes and the 6 th row of heat exchange tubes, and the water gap is the thickness of one row of heat exchange tubes.
