Abstract
Description
Technical Field
[0001] The present invention relates to the technology of household electrical appliances, and more particularly, to an outdoor unit of an air conditioner and an air conditioner. Background Art
[0002] Refrigerants have gone through three generations. Before 1930, there were no specific requirements for refrigerants, and any applicable substance could be used as a refrigerant working medium, mainly natural working media such as NH3, CO2, SO2, and air, but there were many technical problems in their application; the second generation is chlorine-containing synthetic refrigerants, including chlorofluorocarbons (CFCs) and hydrochlorofluorocarbons (HCFCs), but they can cause ozone layer depletion; the third generation is hydrofluorocarbons (HFCs), although the problem of ozone layer depletion has been solved, it will bring a strong greenhouse effect. In the new situation, in order to prevent global warming and reduce the greenhouse effect, people have started to accelerate the pace of replacing CFCs and HCFCs.
[0003] Among the new refrigerants, natural working medium refrigerants have received great attention. There are mainly two categories of natural working media that can be used as refrigerants. One category is specific hydrocarbons, and the most commonly used is propane (R290). However, due to safety problems such as flammability and explosiveness of such substances, its popularization and use are restricted; the other category is inorganic refrigerants, and the more concerned ones are ammonia (R717), carbon dioxide (R744), and water (R718). The biggest drawback of ammonia (R717) is its too strong toxicity. In contrast, the physical properties of water and carbon dioxide are the best, which are both economical and affordable. However, the critical temperature of carbon dioxide is 31 °C and the critical pressure is 7.38 MPa. It is in a supercritical state at a relatively high temperature, the system pressure is very high, and the safety is poor, with relatively large potential safety hazards. Water (R718) is non-toxic, non-flammable, and non-explosive, is ubiquitous in nature, is the most friendly to the ecological environment and human health, and when used as a refrigerant, the system operates in a vacuum state, with high safety, ODP (Ozone Depletion Potential) = 0, and GWP (Global Warming Potential) = 0. Therefore, designing an air conditioner using water as a refrigerant is a technical problem that needs to be urgently solved by those skilled in the art. Summary of the Invention

Detailed implementation manners
[0037] To make the objectives, technical solutions and advantages of the present invention clearer and more understandable, the embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments can be arbitrarily combined with each other.
[0038] The air conditioner outdoor unit provided by the embodiment of the present invention, as Figures 1 to 4 shown, includes: a heat exchanger assembly 100; a steam compressor 200, the steam compressor 200 is located at the front of one end of the heat exchanger assembly 100 (such as the front of the right end), and the second port of the steam compressor 200 is connected to the first port of the heat exchanger assembly 100; a heat exchange component 300 and a throttling component 400, the heat exchange component 300 is located below the steam compressor 200, the second port of the heat exchanger assembly 100 is connected to the first port of the heat exchange component 300 through the throttling component 400, and the second port of the heat exchange component 300 is connected to the first port of the steam compressor 200.
[0039] For this outdoor air conditioner, the high-temperature and high-pressure water vapor discharged from the second port of the water vapor compressor 200 enters the heat exchanger assembly 100. After heat exchange in the heat exchanger assembly 100, medium-temperature and high-pressure condensed water is formed. The medium-temperature and high-pressure condensed water then enters the heat exchange assembly 300 from the second port of the heat exchanger assembly 100 through the throttling component 400. Low-temperature and low-pressure condensed water is formed in the heat exchange assembly 300. The low-temperature and low-pressure condensed water absorbs heat and evaporates to form low-temperature and low-pressure water vapor. The low-temperature and low-pressure water vapor enters the water vapor compressor 200 from the first port of the water vapor compressor 200 for compression, and then is discharged from the second port of the water vapor compressor 200, and so on in a cycle. This outdoor air conditioner uses water, which is more friendly to the ecological environment and human health, as the refrigerant, and the working condition of the refrigerant is a negative pressure condition (such as a vacuum condition). Moreover, the water vapor compressor 200 is located in the front of one end of the heat exchanger assembly 100, and the heat exchange assembly 300 is located below the water vapor compressor 200, with a compact structure, small volume, and convenient installation.
[0040] It can be that the throttling component 400 is set as an electronic expansion valve; or it can be that the throttling component 400 is set as a capillary tube, etc.; it can be that the water vapor compressor 200 is a two-stage water vapor compressor 200, etc. The above can all achieve the purpose of this application, and its gist does not deviate from the design concept of the present invention, so it will not be elaborated here and should all fall within the protection scope of this application.
[0041] In some examples, such as Figure 1 shown, the outdoor air conditioner further includes: a cooling fan, which is located in front of the heat exchanger assembly 100 and is arranged to cool the heat exchanger assembly 100, so that the heat on the heat exchanger assembly 100 is quickly transferred to the external environment.
[0042] Among them, the cooling fan includes a motor bracket, a motor, and a fan blade. The motor is installed on the motor bracket, and the fan blade is installed on the rotating shaft of the motor.
[0043] In some examples, such as Figure 1 and Figure 2 shown, the outdoor air conditioner further includes: a housing 610; and a middle partition 620, which is arranged inside the housing 610 and divides the interior of the housing 610 into a heat exchange chamber and an installation chamber. The main part of the cooling fan and the heat exchanger assembly 100 is arranged in the heat exchange chamber, and the water vapor compressor 200 and the heat exchange assembly 300 are located in the installation chamber.
[0044] Among them, the outer shell 610 includes a chassis, a left side plate, a front side plate, a right side plate, a rear side plate, and a top cover. The motor bracket of the cooling fan, the heat exchanger assembly 100, and the heat exchange assembly 300 are all fixed on the chassis. The left side plate is located on the left side of the middle partition 620, the right side plate is located on the right side of the middle partition 620, the heat exchange chamber is located between the left side plate and the middle partition 620, and the installation chamber is located between the right side plate and the middle partition 620. The outdoor air conditioner further includes an electric control box, which is located in the installation chamber and above the water vapor compressor 200, making full use of this part of the space. Of course, the electric control box can also be arranged in the heat exchange chamber, and the purpose of the present application can also be achieved. Its gist does not deviate from the design concept of the present invention, so it will not be elaborated here and should also fall within the protection scope of the present application.
[0045] In some exemplary embodiments, such as Figures 1 to 4 , Figures 10 to 14 As shown, the heat exchange assembly 300 includes: a first housing 310, the first housing 310 is located below the water vapor compressor 200, and the second port of the heat exchanger assembly 100 is connected to the first port of the first housing 310 through a throttling component 400; and a gas-liquid separator 320, which is arranged at the second port of the first housing 310.
[0046] The medium-temperature and high-pressure condensed water in the heat exchanger assembly 100 enters the first housing 310 through the throttling component 400, forms low-temperature and low-pressure condensed water in the first housing 310. The low-temperature and low-pressure condensed water absorbs heat and evaporates to form low-temperature and low-pressure water vapor. The low-temperature and low-pressure water vapor enters the water vapor compressor 200 through the first port of the water vapor compressor 200 after passing through the gas-liquid separator 320, and then is pumped out through the second port of the water vapor compressor 200. The gas-liquid separator 320 separates the low-temperature water droplets carried in the low-temperature and low-pressure water vapor and makes the separated low-temperature water droplets flow back into the first housing 310, preventing the low-temperature water droplets from entering the water vapor compressor 200 through the first port of the water vapor compressor 200 and damaging the impeller of the water vapor compressor 200.
[0047] In some examples, such as Figure 4 , Figure 11 and Figure 12 As shown, the heat exchange assembly 300 further includes an internal heat exchanger 330, and the internal heat exchanger 330 is arranged in the first housing 310; the outdoor air conditioner further includes: a liquid pump 700, the liquid pump 700 is located at one end (such as the right end) of the heat exchanger assembly 100 and behind the first housing 310, and the liquid pump 700 is also behind the internal heat exchanger 330, for example, directly behind or obliquely behind the internal heat exchanger 330. A first external pipeline 810 and a second external pipeline 820, and the liquid pump 700 and the internal heat exchanger 330 are connected in series between the first external pipeline 810 and the second external pipeline 820.
[0048] The first external pipeline 810 and the second external pipeline 820 are connected to the indoor heat exchanger 10 of the air conditioner indoor unit to form a circulation flow path. There is a circulating liquid (which can be antifreeze, water or other refrigerant media) in the circulation flow path. The liquid pump 700 drives the circulating liquid to flow along the circulation flow path, and heat exchange is carried out with the indoor air through the indoor heat exchanger 10 of the air conditioner indoor unit. The heat absorbed from the indoor air by the indoor heat exchanger 10 of the air conditioner indoor unit is exchanged with the low-temperature and low-pressure water in the first housing 310 through the circulating liquid and the internal heat exchanger 330 in the first housing 310. The low-temperature and low-pressure water in the first housing 310 absorbs the heat in the circulating liquid to form low-temperature and low-pressure water vapor. Both the first external pipeline 810 and the second external pipeline 820 are fixedly arranged through the housing 610. The first external pipeline 810 and the second external pipeline 820 can be fixedly arranged through the side end of the housing 610, for example, on the right side plate. One end of the first external pipeline 810 connected to the indoor heat exchanger 10 of the air conditioner indoor unit and one end of the second external pipeline 820 connected to the indoor heat exchanger 10 of the air conditioner indoor unit are both located outside the housing 610, which is convenient for the first external pipeline 810 and the second external pipeline 820 to be connected to the indoor heat exchanger 10 of the air conditioner indoor unit.
[0049] The liquid pump 700 is located at one end (such as the right end) of the heat exchanger assembly 100 and behind the first housing 310. The liquid pump 700 will not block between the internal heat exchanger 330 and the first external pipeline 810 and the second external pipeline 820 arranged at the side end of the housing 610, making the pipe connection complex, and making the layout of the air conditioner outdoor unit more compact. On the chassis, there is a space for accommodating the liquid pump 700 between the rear side plate and the first housing 310, and between the right side plate and the heat exchanger assembly 100. The liquid pump 700 is fixed on the chassis, and the connection of the liquid pump 700 is more stable.
[0050] Among them, the internal heat exchanger 330 is arranged to have 20 - 40 rows of heat exchange tubes (such as copper tubes). The heat exchange tubes can extend in the horizontal or vertical direction. The length of each heat exchange tube is set to 100 mm - 400 mm, and the diameter of each heat exchange tube is set to 7 mm - 11 mm; it can be that the internal heat exchanger 330 has 20 rows of heat exchange tubes; or it can be that the internal heat exchanger 330 has 30 rows of heat exchange tubes; or it can be that the internal heat exchanger 330 has 40 rows of heat exchange tubes, etc.; it can be that the length of each heat exchange tube is set to 100 mm; or it can be that the length of each heat exchange tube is set to 200 mm; or it can be that the length of each heat exchange tube is set to 300 mm; or it can be that the length of each heat exchange tube is set to 400 mm, etc.; it can be that the diameter of each heat exchange tube is 7 mm; or it can be that the diameter of each heat exchange tube is 9 mm; or it can be that the diameter of each heat exchange tube is 11 mm, etc.; the above can all achieve the purpose of the present application, and its gist does not deviate from the design concept of the present invention, so it will not be elaborated here and should all fall within the protection scope of the present application.
[0051] In some examples, such as Figures 1 to 4 、 Figure 9 shown, the steam compressor 200 is provided with a motor cooling flow path. The motor cooling flow path, the liquid pump 700, and the internal heat exchanger 330 are commonly connected in series between the first external pipeline 810 and the second external pipeline 820, and the motor cooling flow path, the liquid pump 700, and the internal heat exchanger 330 are connected in series. During the process of the circulating liquid flowing in the circulation flow path, the motor of the steam compressor 200 is also cooled. In some examples, the first external pipeline 810, the motor cooling flow path, the internal heat exchanger 330, and the second external pipeline 820 are connected in series in sequence, and the liquid pump 700 can be connected between any two adjacent ones of the first external pipeline 810, the motor cooling flow path, the internal heat exchanger 330, and the second external pipeline 820.
[0052] In some examples, such as Figures 1 to 4 、 Figure 9 shown, the outdoor unit of the air conditioner further includes a liquid tank 900. The liquid tank 900, the liquid pump 700, and the internal heat exchanger 330 are commonly connected in series between the first external pipeline 810 and the second external pipeline 820, and the liquid tank 900, the liquid pump 700, and the internal heat exchanger 330 are connected in series. The liquid tank 900 is used to ensure that the internal heat exchanger 330 is always in a full liquid state. In some examples, the first external pipeline 810, the liquid tank 900, the internal heat exchanger 330, and the second external pipeline 820 are connected in series in sequence, and the liquid pump 700 can be connected between any two adjacent ones of the first external pipeline 810, the liquid tank 900, the internal heat exchanger 330, and the second external pipeline 820. In some examples, the liquid pump 700 is connected to the pipeline between the liquid tank 900 and the internal heat exchanger 330.
[0053] In some examples, such as Figures 1 to 4 、 Figure 9 shown, the steam compressor 200 is provided with a motor cooling flow path. The outdoor unit of the air conditioner further includes a liquid tank 900. The liquid tank 900, the motor cooling flow path, the liquid pump 700, and the internal heat exchanger 330 are commonly connected in series between the first external pipeline 810 and the second external pipeline 820, and the liquid tank 900, the motor cooling flow path, the liquid pump 700, and the internal heat exchanger 330 are connected in series. During the process of the circulating liquid flowing in the circulation flow path, the motor of the steam compressor 200 is also cooled. The liquid tank 900 is used to ensure that the internal heat exchanger 330 is always in a full liquid state.
[0054] In an embodiment, such as Figures 1 to 4 、 Figure 9As shown, the first external pipeline 810, the motor cooling flow path, the liquid tank 900, the internal heat exchanger 330, and the second external pipeline 820 are connected in series in sequence. The liquid pump 700 can be connected between any two adjacent ones of the first external pipeline 810, the motor cooling flow path, the liquid tank 900, the internal heat exchanger 330, and the second external pipeline 820. In some examples, the first external pipeline 810, the motor cooling flow path, the liquid tank 900, the liquid pump 700, the internal heat exchanger 330, and the second external pipeline 820 are connected in series in sequence. The circulating liquid passes through the first external pipeline 810, the motor cooling flow path, the liquid tank 900, the liquid pump 700, the internal heat exchanger 330, and the second external pipeline 820 in sequence, then passes through the indoor heat exchanger 10 of the indoor unit of the air conditioner, and then flows back to the first external pipeline 810, so as to circulate like this.
[0055] In some examples, such as Figures 1 to 4 As shown, the second port of the first housing 310 is located on the top wall of the first housing 310 and protrudes upward. The gas-liquid separator 320 is arranged in the second port of the first housing 310. The liquid tank 900 is annular and sleeved outside the second port of the first housing 310, which makes full use of the space outside the second port of the first housing 310 and supports and fixes the liquid tank 900 through the top wall of the first outer housing 610 in the area outside the second port of the first housing 310. In this way, the structure of the outdoor unit of the air conditioner is more compact, the volume is smaller, and the installation is more convenient.
[0056] Among them, the first port of the water vapor compressor 200 is located at the lower part of the water vapor compressor 200 and is arranged downward, and the first port of the water vapor compressor 200 is located above the second port of the first housing 310. The first port of the water vapor compressor 200 is directly opposite to the second port of the first housing 310. This solution is conducive to the quick docking and connection between the first port of the water vapor compressor 200 and the second port of the first housing 310, and can improve the assembly speed of the outdoor unit of the air conditioner.
[0057] In some examples, such as Figures 10 to 14 As shown, the gas-liquid separator 320 includes: a second housing 321, the second housing 321 has a gas passing channel arranged in the up and down direction, the port at the upper part of the gas passing channel is the second port, and the port at the lower part of the gas passing channel is the first port; and a baffle 322, the baffle 322 is arranged in the gas passing channel and bends and extends in the up and down direction, so that the gas passing channel bends and extends in the up and down direction. When the low-temperature and low-pressure water vapor moves upward through the baffle 322, the liquid droplets carried by the low-temperature and low-pressure water vapor adhere to the baffle 322, and then drip back into the first housing 310 under the action of gravity to achieve gas-liquid separation. Among them, the second housing 321 is installed in the second port of the first housing 310 by interference fit.
[0058] In an embodiment, such as Figures 10 to 14As shown, the baffle 322 includes a plurality of them. The plurality of baffles 322 are sequentially arranged at intervals in the horizontal direction (such as the front-back direction or the left-right direction), and divide the gas passage into a plurality of sub-channels 323 that are sequentially arranged at intervals in the horizontal direction (i.e., the front-back direction or the left-right direction) and extend in a bent manner in the up-down direction. After the low-temperature and low-pressure water vapor separates water droplets through the plurality of sub-channels 323, it enters the water vapor compressor 200 through the first port of the water vapor compressor 200. It can be that the plurality of baffles 322 are arranged in two groups, and the two groups of baffles 322 are symmetrically arranged. The bent part of each baffle 322 is in a V shape, the V-shaped openings of the bent parts of each group of baffles 322 face the same direction, and the V-shaped openings of the bent parts of the two groups of baffles 322 face each other. In this solution, the baffle 322 has a better effect of separating gas and liquid. Among them, the plurality of baffles 322 are connected together. Among the adjacent plurality of baffles 322, except for the end baffles at the beginning and the end, the remaining baffles can be plate-shaped or sheet-shaped baffle fins, and the baffle fins can be in a V shape.
[0059] In some exemplary embodiments, such as Figure 1 , Figure 2 , Figures 5 to 7 As shown, the first heat exchanger assembly 100 includes: a first heat exchanger 110, the first heat exchanger 110 having a plurality of first ports; and a diverter 120 having a plurality of second ports. The diverter 120 is erected at one end (such as the right end) of the first heat exchanger 110 and is behind the water vapor compressor 200. The first port of the diverter 120 is connected to the second port of the water vapor compressor 200, and the plurality of second ports of the diverter 120 are connected to the plurality of first ports of the first heat exchanger 110 in one-to-one correspondence. The second port of the first heat exchanger 110 is connected to the first port of the throttling component 400. The first heat exchanger 110 is set as a finned tube heat exchanger, so that the first heat exchanger 110 has a larger heat exchange area and better heat dissipation effect. The rear end of the middle partition 620 is fixedly connected to the right side plate of the first heat exchanger 110, and the front end of the middle partition 620 is fixedly connected to the front side plate. The front side plate can include one or two arranged in sequence from left to right. The diverter 120 can be located in the installation chamber. The first ports of the first heat exchanger 110 are located in the installation chamber. The heat exchange tubes of the first heat exchanger 110 located in the heat exchange chamber are connected with heat dissipation fins. The heat exchange tubes extend from the heat exchange chamber to the installation chamber. The heat exchange tubes of the first heat exchanger 110 located in the installation chamber are smooth tube sections and are not connected with heat dissipation fins to avoid the temperature rise in the installation chamber. The first heat exchanger 110 is connected to the first port of the first heat exchanger 110 through the first smooth tube section and is connected to the diverter 120.
[0060] Due to the relatively large volume flow rate of high-temperature and high-pressure water vapor, the high-temperature and high-pressure water vapor blown out from the second port of the water vapor compressor 200 is fed into the first heat exchanger 110 in a shunted manner through the shunt 120, so that the distribution of the high-temperature and high-pressure water vapor in the first heat exchanger 110 is more uniform and the heat dissipation effect is better.
[0061] Since the diameter of the second port of the water vapor compressor 200 is relatively large, it is difficult to operate when connecting the second port of the water vapor compressor 200 and the first port of the shunt 120 with a relatively large-diameter rigid pipe (such as a copper pipe). In one embodiment, the second port of the water vapor compressor 200 is located at the rear of the water vapor compressor 200 and is arranged backward, and the first port of the shunt 120 is located in the area from 1 / 2 to 4 / 5 upward from the bottom in the front of the shunt 120 and is arranged forward, and the second port of the water vapor compressor 200 is located in front of the first port of the shunt 120, and the second port of the water vapor compressor 200 is directly opposite to the first port of the shunt 120. This is conducive to the quick docking and connection between the second port of the water vapor compressor 200 and the first port of the shunt 120, which can improve the assembly speed of the outdoor unit of the air conditioner. There is no need to design a bent pipeline between the two, and the second port of the water vapor compressor 200 is located in the upper part of the installation chamber, which is convenient for reasonably arranging the position of the compressor and making the outdoor unit mechanism more compact. The second port of the water vapor compressor 200 can be opened along the tangent direction of the compressor impeller, and the shunt 120 is arranged in the tangent direction of the compressor impeller.
[0062] Among them, the main body of the shunt 120 is a square pipe (such as a copper pipe) with a size of 40 - 60 mm * 40 - 60 mm, and a plurality of second ports of the shunt 120 are 20 - 40 second ports evenly arranged in the up-and-down direction. It can be that the shunt 120 has 20 second ports; or it can be that the shunt 120 has 30 second ports; or it can be that the shunt 120 has 40 second ports, etc.; the above can all achieve the purpose of this application, and its gist does not deviate from the design idea of the present invention, so it will not be elaborated here and all should fall within the protection scope of this application.
[0063] In some examples, such as Figure 1 、 Figure 2 、 Figures 5 to 8As shown, the first heat exchanger 110 also has a plurality of second ports. The plurality of second ports of the first heat exchanger 110 are located behind the plurality of first ports of the first heat exchanger 110. The first heat exchanger assembly 100 further includes a header 130 having a plurality of first ports. The header 130 is erected at one end of the first heat exchanger 110 and is behind the flow divider 120. The plurality of first ports of the header 130 are in communication with the plurality of second ports of the first heat exchanger 110. The second port of the header 130 is in communication with the first port of the throttling member 400. The header 130 can be located in the installation chamber. The second ports of the first heat exchanger 110 are located in the installation chamber. The heat exchange tubes of the first heat exchanger 110 located in the heat exchange chamber are connected with heat dissipation fins. The heat exchange tubes extend from the heat exchange chamber to the installation chamber. The heat exchange tubes of the first heat exchanger 110 located in the installation chamber are smooth tube sections and are not connected with heat dissipation fins. The first heat exchanger 110 is connected to the second port of the first heat exchanger 110 through a second smooth tube section and is connected to the header 130. The header 130 can be located behind the flow divider 120.
[0064] The medium-temperature and high-pressure condensate water in the plurality of flow paths arranged in parallel in the first heat exchanger 110 enters the header 130 one by one along the plurality of first ports of the header 130. After being collected in the header 130, it then flows through the throttling member 400 to the first housing 310.
[0065] Among them, the main body of the header 130 is a square tube (such as a copper tube) with a size of 20 - 40 mm * 20 - 40 mm. The size of the header 130 is smaller than that of the flow divider 120. The plurality of first ports of the header 130 are 20 - 40 first ports evenly arranged in the up-down direction. It can be that the header 130 has 20 first ports; or it can be that the header 130 has 30 first ports; or it can be that the header 130 has 40 first ports, etc. The above can all achieve the purpose of this application. Its gist does not deviate from the design idea of the present invention and will not be elaborated here. All should fall within the protection scope of this application.
[0066] The number of the first ports of the first heat exchanger 110 and the number of the second ports of the first heat exchanger 110 can be the same. The first ports and the second ports of the first heat exchanger 110 are connected in a one-to-one correspondence by heat exchange tubes. The first heat exchanger 110 forms a parallel flow heat exchanger between the flow divider 120 and the header 130, improving the heat exchange efficiency. The heat exchange tubes between the first ports and the second ports of the first heat exchanger 110 can be bent. The heat exchange tubes can be formed by connecting straight tubes or L-shaped tubes and U-shaped tubes, forming a multi-row structure arranged in sequence along the direction from the inside to the outside of the heat exchange chamber. For example, the heat exchange tubes can be bent once to form a two-row structure, or the heat exchange tubes can be bent three times to form a four-row structure, so that both the first ports and the second ports of the first heat exchanger 110 can be located in the installation chamber, facilitating the connection of the first ports of the first heat exchanger 110 to the compressor 200 and the connection of the second ports of the first heat exchanger 110 to the heat exchange assembly 300 through the throttling component 400, reducing the length of the connecting pipelines. When the heat exchange tubes are bent three times to form a four-row structure, the middle second bent structure, such as a U-shaped tube, can be located between the first smooth tube section where the main body of the first heat exchanger 110 is connected to the flow divider 120 and the second smooth tube section where the main body of the first heat exchanger 110 is connected to the header 130, and a receiving space for the bent structure is formed between the two smooth tube sections. In the multi-row heat exchange tube pipelines formed by the heat exchange tubes, at least two rows of heat exchange tube pipelines are staggered in the up-down direction to improve the heat dissipation efficiency, and the bent structures connecting the adjacent two rows of heat exchange tube pipelines staggered in the up-down direction can be inclined.
[0067] Of course, the main bodies of the flow divider 120 and the header 130 can also be circular tubes, etc., which can also achieve the purpose of the present application. The gist thereof does not depart from the design concept of the present invention, and will not be elaborated here, and should also fall within the protection scope of the present application.
[0068] In the present application, the first ports are all inlets and the second ports are all outlets.

[0071] This air conditioner further includes an indoor unit of the air conditioner, as Figure 1 , Figure 2 and Figure 9 shown, the indoor heat exchanger 10 of the indoor unit of the air conditioner is connected to the first external pipeline 810 and the second external pipeline 820 of the outdoor unit of the air conditioner.
[0072] In summary, for the outdoor unit of the air conditioner provided by the embodiments of the present invention, the high-temperature and high-pressure water vapor compressed and sent out from the second port of the water vapor compressor enters the heat exchanger assembly. After heat exchange in the heat exchanger assembly, medium-temperature and high-pressure condensed water is formed. The medium-temperature and high-pressure condensed water then enters the heat exchange assembly from the second port of the heat exchanger assembly through a throttling component, and low-temperature and low-pressure condensed water is formed in the heat exchange assembly. The low-temperature and low-pressure condensed water absorbs heat and evaporates to form low-temperature and low-pressure water vapor. The low-temperature and low-pressure water vapor enters the water vapor compressor from the first port of the water vapor compressor for compression, and then is compressed and sent out from the second port of the water vapor compressor, and so on in a cycle. This outdoor unit of the air conditioner uses water, which is more friendly to the ecological environment and human health, as the refrigerant, and the working condition of the refrigerant is a negative pressure condition (such as a vacuum condition). Moreover, the water vapor compressor is located in the front of one end of the heat exchanger assembly, and the heat exchange assembly is located below the water vapor compressor, with a compact structure, small volume, and convenient installation.
