Description

Technical Field

[0001] The present invention and the technical field of air conditioning particularly relate to an air conditioner outdoor unit and an air conditioner. Background Art

[0002] An air conditioner is a device that absorbs and processes the air around it, usually operating in a closed indoor area or environment, and can perform functions such as cooling, heating, dehumidification, defrosting, and fan, thereby improving the user's living or working environment.

[0003] When the air conditioner is cooling in the summer, condensation water will be generated on the evaporator because the evaporation temperature is lower than the dew point temperature. The condensation water has a low temperature and a large latent heat. However, in the existing technology, the condensation water is generally discharged directly to the outside. The cooling capacity of the condensation water cannot be utilized, resulting in reduced system energy efficiency.

[0004] Accordingly, this field requires a new technical solution to solve the above problems. Summary of the Invention

[0017] In the preferred technical solution of the above-mentioned air-conditioning outdoor unit, the air-conditioner further comprises a spray pipe, which is located above the condenser and can spray condensed water toward the condenser and / or the supercooling pipeline.

[0018] When the above technical solution is adopted, when the condensed water is sprayed onto the condenser or the subcooling pipeline, on the one hand, the heat exchange effect of the condenser and the subcooling pipeline can be improved, and on the other hand, the dust removal effect on the surface of the heat exchanger can be achieved.

[0019] In the preferred technical solution of the above-mentioned air-conditioning outdoor unit, the condenser is configured as a fin heat exchanger, and / or a wet curtain is provided on the air inlet side of the condenser.

[0020] When the above technical solution is adopted, it is beneficial to improve the heat dissipation effect of the condenser, and the air can achieve the effect of cooling and humidification after passing through the wet curtain, thereby further increasing the heat exchange with the condenser.

[0021] In the preferred technical solution of the above-mentioned air-conditioning outdoor unit, the air conditioner further includes a water box, which is capable of storing condensed water.

[0022] When the above technical solution is adopted, the condensed water can be stored and then distributed, which is beneficial to improving the utilization efficiency of the condensed water, thereby improving the heat exchange effect and air conditioning energy efficiency.

[0027] The first box body and the second box body are communicated with each other through the overflow pipe, so that condensed water overflowing from the first box body can enter the second box body through the overflow pipe.

[0028] When adopting the above technical solution, the condensed water first enters the first box body, and the excess condensed water in the first box body enters the second box body through the overflow pipe, which can ensure that the condensed water can immerse the supercooling pipe. The spray pipe uses the excess condensed water flowing into the second box body for spraying.

For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to direct connections, indirect connections through an intermediate medium, or internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in this application based on the specific circumstances.

[0039] As described in the background technology, an air conditioner is a device that absorbs and processes the air around it, usually operates in a closed indoor area or environment, and can achieve functions such as cooling, heating, dehumidification, defrosting, and fan, thereby improving the user's living or working environment.

[0040] When the air conditioner is cooling in the summer, condensation water will be generated on the evaporator because the evaporation temperature is lower than the dew point temperature. The condensation water has a low temperature and a large latent heat. However, in the existing technology, the condensation water is generally discharged directly to the outside. The cooling capacity of the condensation water cannot be utilized, resulting in reduced system energy efficiency.

[0041] In order to solve the problem of reduced system energy efficiency of existing air conditioners due to non-utilization of condensed water, the present application provides an air conditioner outdoor unit, including a shell, a compressor and a condenser, the compressor and the condenser are both arranged in the shell, the inlet of the condenser is connected to the exhaust port of the compressor, the outlet of the condenser is used to be connected to the inlet of the throttling device, the outlet of the throttling device is used to be connected to the inlet of the evaporator, and the outlet of the evaporator is used to be connected to the intake port of the compressor, wherein a subcooling pipeline is provided between the condenser and the throttling device, at least part of the subcooling pipeline is located at the bottom of the leeward side of the condenser and can exchange heat with the condensed water.

[0042] When the above technical solution is adopted, the subcooling pipeline can exchange heat with the condensed water, thereby utilizing the sensible heat of the condensed water and the latent heat of evaporation to cool the subcooling pipeline. In addition, the wind speed at the bottom of the leeward side of the condenser is high, which can greatly increase the evaporation rate, thereby improving the refrigerant subcooling and air conditioning energy efficiency. At the same time, this setting has little impact on the wind field of the condenser itself and does not affect its operating conditions.

[0043] Refer to the following Figure 1 and Figure 2 , describes the air conditioner outdoor unit of this application. Among them, Figure 1 This is a diagram of the internal structure of the air conditioner outdoor unit of this application; Figure 2 This is a schematic diagram of the installation of the water box of this application.

[0044] like Figure 1 and Figure 2 As shown, in a preferred embodiment, the air-conditioning outdoor unit includes a shell 1, in which a compressor (not shown), a condenser 2, a subcooling pipeline 3, a spray pipe 4 and a water box 5 are arranged. The inlet of the condenser 2 is connected to the exhaust port of the compressor, and the outlet of the condenser 2 is used to be connected to the inlet of the throttling device, and the outlet of the throttling device is used to be connected to the inlet of the evaporator, and the outlet of the evaporator is used to be connected to the air intake of the compressor.

[0045] The subcooling pipe 3 is disposed between the condenser 2 and the throttling device. At least a portion of the subcooling pipe 3 is located at the bottom of the leeward side of the condenser 2 and is capable of exchanging heat with the condensed water. This portion of the subcooling pipe 3 is configured as a finned tube, and the shape of this portion of the subcooling pipe 3 is the same as that of the condenser 2; specifically, both are configured as L-shaped. A spray pipe 4 is located above the condenser 2, which is configured as a finned heat exchanger. The spray pipe 4 is connected to the water box 5 and has spray holes on one side of the spray pipe 4 facing the condenser 2 and the subcooling pipe 3 located at the bottom of the leeward side of the condenser 2, so that the spray pipe 4 can spray condensed water toward the condenser 2 and this portion of the subcooling pipe 3.

[0046] The water box 5 can store condensed water. The water box 5 is arranged on the housing 1 (only part of the housing 1 is shown in the figure). At least part of the subcooling pipe 3 is arranged on the water box 5 so that the part of the subcooling pipe 3 can be immersed in the condensed water. Figure 2 The housing 1 includes an air guide ring 11, and the water box 5 is disposed outside the air guide ring 11 and is adapted to the air guide ring 11. Specifically, the water box 5 includes a first box body 51, a second box body 52, and an overflow pipe 53 (only a portion of the overflow pipe 53 is shown in the figure). The first box body 51 is located above the second box body 52, and at least a portion of the subcooling pipeline 3 is disposed in the first box body 51. The first box body 51 and the second box body 52 are connected via the overflow pipe 53, so that condensed water overflowing from the first box body 51 can enter the second box body 52 through the overflow pipe 53.

[0047] In this embodiment, in cooling mode, condensed water generated on the evaporator in the air conditioner's indoor unit is connected to a water box 5 via a pipe, allowing the condensed water to be stored in the water box 5. Specifically, the condensed water first flows into the first box 51. Once the first box 51 is full, the excess condensed water flows into the second box 52 via an overflow pipe 53. The subcooling line 3 consists of two parts: the first subcooling line 3 is located at the bottom of the leeward side of the condenser 2, and the second subcooling line 3 is located inside the water box 5. A spray pipe 4 is connected to the second box 52. A water pump 6 pumps the condensed water from the second box 52 to the spray pipe 4, which sprays the condensed water onto the condenser 2 and the first subcooling line 3. The evaporation of the condensed water removes heat from the condenser 2 and the first subcooling line 3, thereby improving the energy efficiency of the air conditioner. The second part of the supercooling pipe 3 can be immersed in the condensed water in the first box body 51. Since the condensed water has a low temperature and a large latent heat, the second part of the supercooling pipe 3 can use the sensible heat of the condensed water to cool down on the one hand, and on the other hand, it can use the latent heat of evaporation of the condensed water in the water box 5 to further cool down, thereby realizing a function similar to that of an evaporative condenser.

[0048] It should be explained that, in this embodiment, the subcooling pipe 3 is configured as a finned tube, but its configuration is not fixed. In an alternative embodiment, the first portion of the subcooling pipe 3 can be configured as a bare tube, and a humidifying cotton can be provided on the outside of the subcooling pipe 3. Condensed water can be sprayed onto the humidifying cotton to moisten the humidifying cotton. The humidifying cotton can evenly distribute the condensed water, avoid local heat exchange, and fully utilize the area of ​​the subcooling pipe 3, thereby improving the heat exchange effect of the subcooling pipe 3. In another alternative embodiment, when the subcooling pipe 3 is configured as a finned tube, a humidifying cotton can be provided on the outside of the finned tube.

[0049] In addition, in this embodiment, the spray pipe 4 is located above the condenser 2 and can spray condensed water onto both the first portion of the subcooling pipe 3 and the condenser 2. However, this arrangement is not fixed. In an alternative embodiment, the spray pipe 4 can spray condensed water only onto the subcooling pipe 3. In this case, it is not necessary to use the water pump 6 to transport the condensed water to the spray pipe 4. For example, the spray pipe 4 can be located above the subcooling pipe 3, and the water box 5 can be located above the spray pipe 4. In this case, the condensed water can also be transported to the spray pipe 4 by gravity. In another alternative embodiment, a receiving tank can be provided at the bottom of the shell 1. In this case, the spray pipe 4 can be omitted, and the condensed water in the water box 5 can be drained to the receiving tank by gravity or a water pump. The first part of the subcooling pipeline 3 can be provided in the receiving tank so that the bottom of this part of the subcooling pipeline 3 can be in contact with the condensed water, while the upper part can dissipate heat through the flowing air, and at this time, the setting of humidification cotton or finned tubes can further ensure the heat exchange area of ​​the subcooling pipeline 3.

[0050] Furthermore, in this embodiment, the spray holes on the spray pipe 4 are configured as elongated holes, but this configuration is not fixed. In an alternative embodiment, the spray holes on the spray pipe 4 can be configured as multiple circular holes. Furthermore, the number of spray pipes 4 is not fixed. In an alternative embodiment, two spray pipes 4 can be provided, one for spraying condensed water onto the condenser 2 and the other for spraying condensed water onto the first subcooling pipe 3.

[0051] It will be understood by those skilled in the art that, in the present embodiment, the condenser 2 is configured as a fin heat exchanger, and by spraying condensed water onto the condenser 2, on the one hand, the cooling effect of the condenser 2 can be improved, and on the other hand, the dust removal effect on the surface of the condenser 2 can be achieved. However, its setting is not static. In an alternative embodiment, a wet curtain can be provided on the air inlet side of the condenser 2, and the spray pipe 4 can spray condensed water onto the wet curtain. After the air passes through the wet curtain, the effect of cooling and humidification can be achieved, thereby further increasing the heat exchange with the condenser 2. Moreover, in the present embodiment, the condenser 2 and the first part of the subcooling pipeline 3 are both configured as L-shaped, but the configuration is not fixed. Those skilled in the art can change the shape of the condenser 2 and the first part of the subcooling pipeline 3 according to needs, for example, the condenser 2 and the first part of the subcooling pipeline 3 are both configured as a straight line, or the subcooling pipeline 3 is configured as an S-shaped.

[0052] It should also be explained that, in this embodiment, the water box 5 includes a first box body 51, a second box body 52, and an overflow pipe 53. The excess condensed water in the first box body 51 flows into the second box body 52 through the overflow pipe 53. The second part of the subcooling pipeline 3 is only provided in the first box body 51. The amount of condensed water required here is relatively large. This arrangement can ensure that the subcooling pipeline 3 is always immersed in the condensed water, and the excess condensed water can be supplied to the condenser 2 or the first part of the subcooling pipeline 3. However, this arrangement is not necessary. In an alternative embodiment, the subcooling pipeline 3 can be provided in the entire water box 5, and the water box 5 can also be provided as only one box body or multiple boxes. In another alternative embodiment, the overflow pipe 53 can be omitted. In this case, the first box body 51 and the second box body 52 can be relatively independent, which also does not affect the normal function of the water box 5. In addition, it is not necessary to set the water box 5 outside the air guide ring 11. Those skilled in the art can make changes as needed, as long as it does not affect the normal functions of components such as the water box 5 and the condenser 2. Moreover, when changing the setting position of the water box 5, the shape of the water box 5 can also be changed as needed, for example, the water box 5 can be set to a cylinder or a cube. In addition, in this embodiment, the second part of the subcooling pipe 3 is set as a light pipe, and the shape of the subcooling pipe 3 is adapted to the shape of the first box body 51 and is wound in an S shape, but its setting is not fixed. In an alternative embodiment, the second part of the subcooling pipe 3 can also be set as a finned tube. In another alternative embodiment, those skilled in the art can also change the shape of the subcooling pipe 3 as needed, as long as it does not affect the normal functions of the subcooling pipe 3 and the first box body 51.

[0053] Those skilled in the art will appreciate that, in this embodiment, the provision of the water box 5 allows the condensed water to be stored and then distributed, which is beneficial to improving the utilization efficiency of the condensed water, thereby improving the heat exchange effect and the energy efficiency of the air conditioner. However, the provision of the water box 5 is not necessary. In an alternative embodiment, the condensed water generated on the evaporator can directly enter the holding tank at the bottom of the shell 1 after flowing to the air conditioner outdoor unit. At this time, the excess condensed water in the holding tank can be directly discharged to the outside through the drain port on the shell 1, or it can be directly sprayed onto the condenser 2 and the subcooling pipe 3 at the bottom of the condenser 2. However, considering the improvement of the utilization efficiency of the condensed water, the provision of the water box 5 is a better choice.

[0054] Those skilled in the art can also understand that, in the present embodiment, the first part of the subcooling pipe 3 and the second part of the subcooling pipe 3 are arranged in series, that is, the refrigerant flowing out of the condenser first enters the first part of the subcooling pipe 3 located at the bottom of the leeward side of the condenser 2, and then enters the second part of the subcooling pipe 3 located in the water box 5, but its setting is not static, and those skilled in the art can change it according to needs. In an alternative embodiment, the order of the first part of the subcooling pipe 3 and the second part of the subcooling pipe 3 can be changed, or the first part of the subcooling pipe 3 and the second part of the subcooling pipe 3 can be arranged in parallel, that is, a part of the refrigerant flowing out of the condenser is supercooled through the first part of the subcooling pipe 3, and the other part of the refrigerant is supercooled through the second part of the subcooling pipe 3, as long as it does not affect the normal function of the subcooling pipe 3. In addition, although the present embodiment is introduced in conjunction with a split air conditioner, this is not intended to limit the scope of protection of the present application. Without deviating from the principles of the present application, those skilled in the art may apply the present application to other application scenarios, for example, applying the supercooling principle of the supercooling pipe 3 in the present application to an integrated air conditioner.

[0055] The present application also provides an air conditioner, which includes any of the above air conditioner outdoor units and air conditioner indoor units, the evaporator is arranged in the air conditioner indoor unit, and the throttling device is arranged in the air conditioner outdoor unit or the air conditioner indoor unit.

[0056] When the above-mentioned air-conditioning outdoor unit is adopted, the low-temperature condensed water produced by the evaporator in the air-conditioning indoor unit can be utilized. The sensible heat of the condensed water and the latent heat of evaporation can be utilized to cool the supercooling pipe 3 through heat exchange between the supercooling pipe 3 and the condensed water. In addition, the wind speed at the bottom of the leeward side of the condenser 2 is large, which can greatly increase the evaporation rate, thereby improving the refrigerant supercooling and air-conditioning energy efficiency. At the same time, this setting has little impact on the wind field of the condenser 2 itself and does not affect its operating conditions.

[0057] Those skilled in the art will appreciate that although some embodiments described herein include certain features included in other embodiments but not other features, combinations of features from different embodiments are intended to be within the scope of this application and to form different embodiments. For example, in the claims of this application, any of the claimed embodiments may be used in any combination.

[0058] Thus far, the technical solutions of the present application have been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it is readily understood by those skilled in the art that the scope of protection of the present application is obviously not limited to these specific embodiments. Without departing from the principles of the present application, those skilled in the art may make equivalent changes or substitutions to the relevant technical features, and the technical solutions after such changes or substitutions will fall within the scope of protection of the present application.
