Description

Technical Field

[0001] The utility model relates to the technical field of air conditioning, in particular to an air conditioner. Background Art

[0002] Air conditioners are commonly used electrical equipment, widely used in various buildings. Air conditioners are used to regulate indoor air, including regulating air temperature, humidity, air quality, humidifying, dehumidifying, introducing fresh air, etc. Air conditioners consist of a vapor compression refrigeration cycle system consisting of an evaporator, condenser, compressor, throttling device and other necessary components. The fan outputs cold / hot air to achieve cooling and heating of the indoor environment.

[0003] Many air conditioners include water systems, such as central air conditioning chillers, fluorine-water air conditioners, water-water-water air conditioners, etc. In water system air conditioners, as the air conditioner continues to run, the water system in the unit will inevitably produce air, mainly from the following parts: residual air that was not completely emptied when the unit was installed, changes in dissolved air content caused by changes in water temperature and inconsistent start and stop states of the unit system, a small amount of air mixed in during water replenishment due to lack of water in the system after operation, and a small amount of air infiltrated from connections such as system valves.

[0004] The presence of air in the air conditioning water system can easily cause various faults, such as cavitation of the water pump, which can reduce the efficiency of the water pump, increase the noise of the water pump, and reduce the service life and performance of the water pump. Utility Model Content

[0005] The purpose of the utility model is to provide an air conditioner which overcomes the above problems or at least partially solves the above problems.

[0006] One purpose of the utility model is to solve the problem that excessive gas is easily accumulated in the air conditioning water system and thus easily causes malfunctions.

[0007] Another purpose of the utility model is to facilitate users to timely understand the air content of the water system so as to perform exhaust operation in time.

[0008] In particular, the utility model provides an air conditioner, comprising a water system, wherein

[0009] The water system has a heat exchange device configured to allow water in the water system to exchange heat with a refrigerant in the heat exchange device;

[0010] The water system further comprises an exhaust pipe, one end of which is connected to a water pipe of the water system, and the exhaust pipe is provided with an exhaust valve, which is used to open and close the exhaust pipe so as to discharge gas from the exhaust pipe in an open state; and

[0011] At least a partial section of the exhaust pipe is a transparent structure so that the water level inside the exhaust pipe can be seen.

[0012] Optionally, the air conditioner further comprises a casing defining a receiving space, wherein the heat exchange device and the exhaust pipe are arranged inside the casing; and

[0013] The housing is provided with a transparent window, and the position of the transparent window is opposite to the transparent part of the exhaust pipe, so that a user can observe the water level of the exhaust pipe through the transparent window outside the housing.

[0014] Optionally, at least one water level scale line is provided at the transparent window.

[0015] Optionally, the transparent window is made of transparent plastic and is embedded in a mounting hole provided in the housing.

[0016] Optionally, the air conditioner further comprises a casing defining a receiving space, wherein the heat exchange device and the exhaust pipe are arranged inside the casing; and

[0017] The casing is provided with an opening, and the exhaust pipe extends out of the casing through the opening so as to exhaust air to the outside of the casing, and the exhaust valve is arranged outside the casing.

[0018] Optionally, the connection point between the exhaust pipe and the water pipe is not lower than the highest water level of the water pipe of the water system.

[0019] Optionally, the heat exchange device is of a shell-and-tube type, having a vertically extending water pipe for water inlet; and

[0020] The exhaust pipe is connected to the top of the water pipe.

[0021] Optionally, the exhaust pipe and the water pipe are connected by threads.

[0022] Optionally, the exhaust pipe as a whole is a vertical pipe extending from bottom to top, and the exhaust valve is arranged at the top end of the exhaust pipe.

[0023] Optionally, the water system comprises a water pump for achieving water flow in the water system.

[0024] In the air conditioner of the utility model, the water system includes an exhaust pipe. One end of the exhaust pipe is connected to the water pipe of the water system to form a bypass structure, which enables the exhaust pipe to store some gas in the water system. An exhaust valve is installed on the exhaust pipe, and the exhaust valve is used to open and close the exhaust pipe. When the air conditioner is in normal operation, the exhaust valve is in a closed state. When the water flows normally in the water pipe, the mixed gas in it reaches the connection between the exhaust pipe and the water pipe, enters the exhaust pipe, and accumulates in the upper part of the exhaust pipe. When exhaust is required, the exhaust valve can be opened to discharge the gas in the exhaust pipe under the action of water pressure, which greatly reduces the gas in the water system. In this way, the utility model solves the problem that too much gas is prone to appear in the air conditioner water system, which is easy to cause malfunctions.

[0025] Furthermore, the utility model makes part of the exhaust pipe a transparent structure so that the water level in the exhaust pipe is visible. In this way, the user can judge the amount of gas accumulated in the exhaust pipe according to the water level in the exhaust pipe, and then decide whether to exhaust the gas, so that the user can reasonably control the exhaust rhythm and avoid the exhaust frequency being too high or too low. Specifically, the gas with low density must be above the water. The lower the water level, the more gas there is, and the higher the water level, the less gas there is. When the user judges that there is enough gas, the exhaust valve can be opened to exhaust the gas.

[0026] Furthermore, in the air conditioner of the utility model, the casing is provided with a transparent window, and the position of the transparent window is opposite to the transparent part of the exhaust pipe, so that the user can observe the water level of the exhaust pipe through the transparent window outside the casing. In this way, there is no need to arrange the exhaust pipe outside the casing, making the overall structure of the air conditioner more compact and beautiful.

[0027] Furthermore, in the air conditioner of the utility model, an opening is opened in the casing, an exhaust pipe extends out of the casing through the opening, and an exhaust valve is arranged outside the casing. The user can complete the exhaust operation outside the casing, which is more convenient to operate and has a very ingenious structure.

[0028] Furthermore, in the air conditioner of the present invention, the connection point between the exhaust pipe and the water pipe is not lower than the highest water level of the water pipe of the water system, which makes the exhaust pipe located higher, which is conducive to the air in various parts of the water pipe to enter the exhaust pipe more smoothly.

[0029] Furthermore, in the air conditioner of the utility model, the exhaust pipe and the water pipe are connected by threads, which can avoid the exhaust pipe and the water pipe being made as one piece, thus avoiding additional troubles in the design and processing of the two.

[0042] An embodiment of the utility model provides an air conditioner.

[0043] Air conditioners are used to regulate indoor air. Specifically, air conditioners are used to regulate indoor air, including regulating the temperature, humidity, and air quality of the air, as well as humidifying, dehumidifying, introducing fresh air, purifying, etc. The air conditioner can be composed of an evaporator, a condenser, a compressor, a throttling device, and other necessary components to form a vapor compression refrigeration cycle system, and output cold air / hot air through the indoor fan to achieve cooling and heating of the indoor environment. The specific principles of air conditioners are well known to those skilled in the art and will not be repeated here.

[0044] The air conditioner of the embodiment of the utility model includes not only the above-mentioned vapor compression refrigeration cycle system, but also a water system. The water system promotes the circulation of water through a water pump, so that the water exchanges heat with the heat exchange device of the vapor compression refrigeration cycle system, so that the water is heated or cooled, and forms hot water or cold water for subsequent use. For example, cold water / hot water is used as a refrigerant and transported to the end of the air conditioner through a pipeline to cool / heat the indoor environment, or hot water is supplied to the user for direct use, or hot water is transported to the floor heating pipeline to heat the room.

[0045] Specifically, the air conditioner with a water system can be a central air conditioning chiller, a natural fluorine ground water air conditioner, a natural water ground water air conditioner, etc. The water system and the corresponding air conditioner are very common in the field of air conditioning and are well known to those skilled in the art, so they will not be introduced in detail here.

[0046] Figure 1 is a structural schematic diagram of an air conditioner according to an embodiment of the utility model; Figure 2 yes Figure 1 A schematic structural diagram of a heat exchange device 50 in the air conditioner shown; Figure 3 It is a circulation flow diagram of an air conditioner according to an embodiment of the utility model.

[0047] like Figures 1 to 3 As shown, the air conditioner of the embodiment of the utility model can generally include a water system 100, and the water system 100 has a heat exchange device 50, and the heat exchange device 50 is configured to make the water in the water system 100 and the refrigerant exchange heat in the heat exchange device 50. Specifically, when the heat exchange device 50 plays the role of a condenser, the water and the refrigerant exchange heat to obtain hot water. When the heat exchange device 50 plays the role of an evaporator, the water and the refrigerant exchange heat to obtain cold water. The water system 100 may also include a water pump 90 for realizing the flow of water in the water system 100.

[0048] by Figure 3 For example, Figure 3 This is the circulation flow diagram of the natural fluorine and ground water air conditioner in heating mode. Note that Figure 3 Not all refrigeration components of the Tianfengdishui air conditioner are shown, and some refrigeration components that are only activated in cooling mode are hidden.

[0049] like Figure 3 As shown, in the embodiment of the utility model, the components used in the air conditioning heating cycle may generally include a compressor 20, a first heat exchanger 30, a throttling device 40, a heat exchange device 50, a floor heating coil 80 and a water pump 90. The compressor 20, the heat exchange device 50, the throttling device 40 and the first heat exchanger 30 are connected in sequence by pipelines to form a vapor compression cycle system. The water pump 90, the heat exchange device 50 and the floor heating coil 80 are connected in sequence by water pipes 51 to form a water system 100.

[0050] Figure 3 The solid arrows indicate the flow direction of the refrigerant in the air conditioning heating mode, and the hollow arrows indicate the flow direction of the water in the air conditioning heating mode.

[0051] The following describes the cycle process of the vapor compression cycle system in the air conditioning heating mode. Figure 3As shown, in the air-conditioning heating mode, the refrigerant is compressed by the compressor 20 to form a high-temperature and high-pressure gaseous refrigerant. The high-temperature and high-pressure gaseous refrigerant flows to the heat exchange device 50. The heat exchange device 50 is a water-fluorine heat exchanger, such as a shell-and-tube heat exchanger, a shell-and-tube heat exchanger, and the like. The high-temperature and high-pressure gaseous refrigerant releases heat in the heat exchange device 50, transfers the heat to the water, and heats up the water to form hot water. The temperature of the cooled refrigerant decreases to achieve condensation, and then after throttling by the throttling device 40, a low-temperature and low-pressure gas-liquid two-phase state is formed. The gas-liquid two-phase refrigerant passes through the first heat exchanger 30, absorbs heat from the outside, and its temperature rises, evaporates into a gaseous state, and is then re-absorbed by the compressor 20. The above-mentioned compression, condensation, throttling and evaporation processes are repeated to form a vapor compression heating cycle.

[0052] Driven by the water pump 90, the water in the water system 100 circulates and forms hot water after being heated by the heat exchange device 50. The hot water is then pumped into the floor heating coil 80, so that the floor heating coil 80 heats the floor, and the indoor air is heated by the floor, thereby achieving a heating process for the indoor environment and forming floor heating. Floor heating is more comfortable than traditional air conditioning heating, and does not cause cold feet due to lack of hot air near the floor in traditional air conditioning heating. The floor heating coil 80 uses air conditioning to produce hot water, which is more energy efficient than using a gas furnace to produce hot water.

[0053] The water system 100 of the air conditioner, such as the above-mentioned natural fluorine and ground water water system 100, often accumulates gas in the pipes. These gases specifically include: residual air that was not completely exhausted when the air conditioner was installed; changes in dissolved air content caused by changes in water temperature and inconsistent start and stop states of the air conditioning unit system; a small amount of air mixed in when replenishing water due to lack of water after the air conditioning system is running; and a small amount of air infiltrating into connections such as system valves.

[0054] The presence of air in the air conditioning water system 100 can easily cause various faults, such as cavitation of the water pump 90, which can cause damage to the impeller and pump body of the water pump 90, reduce the operating efficiency of the water pump 90, increase the noise of the water pump 90, and reduce the service life and performance of the water pump 90. In addition, the presence of air in the water can also cause cavitation in the heat exchange device 50, reducing the heat exchange efficiency of the heat exchange device 50.

[0055] To solve this problem, Figure 2 As shown, in the air conditioner of the embodiment of the utility model, the water system 100 also includes an exhaust pipe 60. One end of the exhaust pipe 60 is connected to the water pipe 51 of the water system 100. This is equivalent to being connected to the water pipe 51 in a bypass manner. The exhaust pipe 60 is installed with an exhaust valve 70, and the exhaust valve 70 is used to open and close the exhaust pipe 60. Under the action of the water pump, the water in the water system has a large water pressure. When the exhaust valve 70 is in an open state, the gas in the exhaust pipe 60 will be discharged under the action of the water pressure.

[0056] In addition, at least a portion of the exhaust pipe 60 is a transparent structure so that the water level in the exhaust pipe 60 can be visible. Specifically, the exhaust pipe 60 can be a transparent structure as a whole. Alternatively, a section of the exhaust pipe 60 can be a transparent structure, and the transparent section and the non-transparent section can be screwed together. For example, in some embodiments, the transparent section of the exhaust pipe 60 can be a transparent plastic tube.

[0057] In the air conditioner of the embodiment of the utility model, the water system 100 includes an exhaust pipe 60. One end of the exhaust pipe 60 is connected to the water pipe 51 of the water system 100 to form a bypass structure, which enables the exhaust pipe 60 to collect and store some gas in the water system 100. In addition, the exhaust pipe 60 is installed with an exhaust valve 70, which is used to open and close the exhaust pipe 60.

[0058] When the air conditioner is in normal operation, the exhaust valve 70 is closed. The water flows normally in the water pipe 51, and the gas mixed in the water flows into the exhaust pipe 60 when it reaches the connection between the exhaust pipe 60 and the water pipe 51, and because the density of the gas is less than that of water, the gas will accumulate at the upper part of the exhaust pipe 60.

[0059] When the user determines that exhaust is needed, the user can open the exhaust valve 70 to discharge the gas in the exhaust pipe 60 under the action of water pressure, so that the gas in the water system 100 can be emptied in time. Even if the gas cannot be exhausted, at least the gas in the water system 100 can be greatly reduced. It can be seen that the embodiment of the utility model solves the problem that too much gas is easy to appear in the water system 100 of the air conditioner, which is easy to cause various faults, and the structure is simple and ingenious. The embodiment of the utility model is particularly suitable for a natural fluorine ground water air conditioner with two upper and lower fans in the outdoor unit.

[0060] In addition, the inventors have realized that although the exhaust pipe 60 can accumulate gas and the exhaust valve 70 can exhaust the gas, the user does not know when exhaust is needed.

[0061] One solution is to detect the water level or air pressure through a sensor, and judge the amount of gas accumulated in the exhaust pipe 60 by the change of the water level or air pressure, and then decide whether to start the exhaust process. And when exhaust is needed, the air conditioning control panel controls the electric exhaust valve 70 to realize the exhaust process. On the one hand, this solution increases the cost of air conditioning, and on the other hand, it often leads to misjudgment due to the unstable pressure in the exhaust pipe 60.

[0062] To solve this problem, the embodiment of the utility model makes part of the section of the exhaust pipe 60 a transparent structure so that the water level inside the exhaust pipe 60 is visible. In this way, the user can judge the amount of gas accumulated in the exhaust pipe 60 according to the water level in the exhaust pipe 60, and then decide whether to exhaust the gas, so that the user can reasonably control the exhaust rhythm and avoid the exhaust frequency being too high or too low. Specifically, the density of gas is obviously lower than that of water, and it must be above the water. Therefore, the lower the water level in the exhaust pipe 60, the more gas there is above it; the higher the water level in the exhaust pipe 60, the less gas there is. When the user determines that there is enough gas, the exhaust valve 70 can be opened to exhaust the gas. The embodiment of the utility model exhausts the gas manually, which is lower in cost and has stronger structural reliability.

[0063] In some embodiments of the present invention, Figure 1 As shown, the air conditioner further includes a casing 10. The casing 10 defines a receiving space to receive the main components of the air conditioner. The heat exchange device 50 and the exhaust pipe 60 are disposed inside the casing 10. Figure 1 The outdoor unit of the natural fluorine and ground water air conditioner is shown in the figure. The compressor 20, the first heat exchanger 30, the throttling device 40, and the heat exchange device 50 are all arranged inside the casing 10.

[0064] In some embodiments of the present invention, Figure 1 As shown, a transparent window 112 may be provided on the housing 10. The transparent window 112 is located opposite to the transparent portion of the exhaust pipe 60, so that the user can observe the water level of the exhaust pipe 60 through the transparent window 112 outside the housing 10 to determine whether the exhaust operation needs to be started. In this way, there is no need to set the exhaust pipe 60 outside the housing 10, making the overall structure of the air conditioner more compact and beautiful.

[0065] Of course, in some alternative embodiments, the exhaust pipe 60 may be entirely or mostly located outside the housing 10 so that the user can observe the water level and operate the exhaust valve 70. Such a design can avoid the need for a transparent window 112.

[0066] Further, in some embodiments of the present invention, Figure 1 As shown, the transparent window 112 can be made of transparent plastic. Moreover, the transparent window 112 is embedded in the mounting hole 115 provided in the housing 10. Of course, the transparent window 112 can also be made of glass, and a frame is provided around the glass to be embedded in the mounting hole 115 provided in the housing 10.

[0067] It is preferred that the transparent window 112 is disposed on the front plate 11 of the housing 10 so that the transparent window 112 is disposed forward for easy observation by the user. One or more fastening structures (e.g., binding structures) may be disposed between the exhaust pipe 60 and the inner wall of the housing 10 (specifically, the inner wall of the front plate 11) to fix the exhaust pipe 60 to the inner wall of the housing 10 to avoid displacement, to make the position of the exhaust pipe 60 more stable, and to prevent the transparent section of the exhaust pipe 60 from deviating from the transparent window 112, so that the user cannot observe the water level of the exhaust pipe 60 from the outside of the housing 10.

[0068] Furthermore, in some embodiments of the present invention, at least one water level scale line is provided at the transparent window 112 , and the water level scale line is used to indicate the water level to assist the user in making exhaust judgments.

[0069] For example Figure 1 As shown, a minimum water level scale line x can be set. When the water level reaches or is lower than the minimum water level scale line x, it indicates that the water level is low enough, that is, it indicates that there is enough gas in the exhaust pipe 60, and it is recommended to perform exhaust operation.

[0070] Alternatively, a plurality of water level scale lines may be provided, each water level scale line marking a specific gas volume corresponding to the current water level for user judgment.

[0071] The inventors have realized that the gas discharged from the exhaust pipe 60 has a high moisture content and is relatively humid. If the gas is discharged into the interior of the housing 10, it will affect the life of the internal components, especially the controller. Based on this, in some embodiments of the present invention, Figure 1 As shown, the housing 10 may be provided with an opening 114, and the exhaust pipe 60 may extend out of the housing 10 through the opening 114, so that the exhaust pipe 60 exhausts air to the outside of the housing 10. In addition, such a configuration also facilitates the arrangement of the exhaust valve 70 outside the housing 10. The user may complete the exhaust operation outside the housing 10, which is more convenient and has a very ingenious structure.

[0072] Furthermore, the exhaust valve 70 may be fixed to the opening 114 by means of a snap connection or a threaded connection, so that its position is more stable.

[0073] Since the density of air is obviously lower than that of water, the air will gradually gather upwards as it circulates with the water in the water system 100 , and eventually be at the highest position of the water pipe 51 in the water system 100 .

[0074] To this end, in some embodiments of the present invention, the connection point between the exhaust pipe 60 and the water pipe 51 can be made not lower than the highest water level T of the water pipe 51 of the water system 100, so that the air at all locations of the water pipe 51 can more smoothly enter the exhaust pipe 60. Furthermore, the connection point between the exhaust pipe 60 and the water pipe 51 can be located at the highest point of the water pipe 51 in the water system 100, so as to further ensure that the air at all locations of the water pipe 51 can more smoothly enter the exhaust pipe 60.

[0075] In some embodiments of the present invention, Figure 2 As shown, the heat exchange device 50 can be a shell-and-tube heat exchanger, and the heat exchange device 50 has a vertically extending water pipe 51 for water inlet. The exhaust pipe 60 is connected to the top of the water pipe 51. Since there is more gas in the water inlet water pipe 51, the exhaust pipe 60 is connected to the water inlet water pipe 51 and is located at the top of the water pipe 51, which can better collect the gas and prevent the gas from flowing further downward from the source. Before the water enters the heat exchange device 50, the water is separated from the gas, and the air is prevented from entering the heat exchange device 50 to reduce its heat exchange efficiency.

[0076] In some embodiments of the present invention, Figure 2 As shown, the exhaust pipe 60 and the water pipe 51 can be connected by threads to avoid the exhaust pipe 60 and the water pipe 51 being made in one piece, thereby avoiding additional troubles in the design and processing of the two. Figure 2 As shown, one end of the exhaust pipe 60 is provided with a thread, and the water pipe 51 is provided with a thread, and the two are threadedly connected, and a seal is provided between the two to achieve sealing and avoid water leakage.

[0077] In some embodiments, Figure 2 As shown, the exhaust pipe 60 can be a vertical pipe extending from bottom to top, and the exhaust valve 70 is arranged at the top of the exhaust pipe 60. In this embodiment, the exhaust pipe 60 is arranged as a vertical pipe extending from bottom to top, so that the gas can more easily flow upwards due to its low density and be concentrated in the exhaust pipe 60. The exhaust valve 70 is arranged at the top of the exhaust pipe 60 so that the gas can be released more thoroughly during exhaust.

[0078] At this point, those skilled in the art should recognize that, although multiple exemplary embodiments of the present invention have been shown and described in detail herein, many other variations or modifications that conform to the principles of the present invention can still be directly determined or derived from the contents disclosed in the present invention without departing from the spirit and scope of the present invention.
