Abstract
Description
Technical Field
[0001] The present application belongs to the technical field of air-conditioning systems, and in particular relates to an oil separation component, a compressor component and an air-conditioning system. Background Art
[0002] In the refrigeration system, the oil separator is an important device. Its main function is to separate the refrigerant oil droplets in the compressor exhaust. On the one hand, it prevents the refrigerant oil from entering the condenser and other heat exchangers with the refrigerant vapor, causing a decrease in heat exchange efficiency (studies have found that when the circulation volume of the refrigerant oil is 5%, the evaporator heat exchange rate decays by 10%; when the oil content in the system increases by 1%, the system COP decays by 2.5%). On the other hand, it can prevent the refrigerant oil involved in the circulation from remaining in the system, causing the compressor to fail due to lack of oil. Therefore, an oil separator is usually set between the compressor and the condenser. The refrigerant oil is separated from the refrigerant vapor through the separation effect of the oil separator to prevent the refrigerant oil from participating in the system circulation. At the same time, the separated refrigerant oil is delivered to the compressor in time to avoid damage to the compressor due to lack of oil. Therefore, the separation effect of the oil separator has a great influence on the performance of the unit. Ensuring the good separation effect of the oil separator can not only prevent excessive lubricating oil from participating in the circulation and affecting the system performance, but also ensure the normal oil return and safe operation of the compressor.
[0003] However, the gas flow rate in the oil separator of the related technology is high and / or the flow field design is unreasonable, the oil-gas separation efficiency is low, and the unseparated refrigeration oil enters the system circulation with the gas phase refrigerant, resulting in oil leakage during unit operation, which not only affects the COP of the refrigeration system, but also easily causes the compressor to lack oil and be damaged.
[0004] Among them, the oil separator products dominated by external vertical separation are applicable to limited working conditions (inlet speed 8-12m / s), and the inertial separation and centrifugal separation areas account for about 80%, and the filter adsorption separation accounts for 20%. The high dependence on the intake speed leads to the serious impact of the separation efficiency of the oil separator once the gas speed fluctuates. In addition, the gas phase refrigerant inside the oil separator will impact the refrigeration oil collected at the bottom of the container, causing liquid level fluctuations and foaming, reducing the oil return efficiency of the unit return pipe, and affecting the stable operation of the liquid level gauge or oil level mirror, which will cause system false alarms and other faults.
[0005] Therefore, in order to solve the above problems, it is necessary to adjust the gas flow rate and flow field in the oil separator, improve the oil-gas separation efficiency, avoid fluctuations in the refrigerant oil level and the generation of foam. It is urgent to develop an efficient oil separator that can control the flow rate, improve efficiency, eliminate foam, and stabilize the oil level.

[0047] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means intended to limit the present application and its application or use. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.
[0048] In the description of the present application, it should be understood that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the drawings, and are only for the convenience of describing the present application and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the device or element referred to must have a specific direction or be constructed and operated in a specific direction, and therefore cannot be understood as limiting the scope of protection of the present application; the directional words "inside and outside" refer to the inside and outside relative to the contours of each component itself.
[0049] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.
[0050] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of this application.
[0051] See also Figures 1 to 10 As shown, according to an embodiment of the present application, an oil separation component includes:
[0052] The cylinder 1 is vertically arranged and sealed at both ends; a first inlet 4 is arranged on the side wall of the cylinder 1, a first air outlet 5 is arranged on the top, and an oil return port 6 is arranged on the bottom;
[0053] The deceleration tube 23 is arranged in the cylinder 1, and its outlet is connected to the first air outlet 5; the deceleration tube 23 is vertically arranged, and the airflow therein flows from bottom to top; the inner diameter of the deceleration tube 23 is gradually contracted and expanded along the flow direction of the airflow.
[0054] The present application sets a deceleration tube 23 in the cylinder 1, so that the intake air is diffused first, and the change of the intake air speed will not affect the separation effect; and the airflow is further condensed and diffused through the deceleration tube 23, which changes the flow rate and improves the separation effect.
[0055] The first inlet 4 is arranged on the side wall of the cylinder 1. When the airflow enters the cylinder 1 through the first inlet 4, the volume increases and the corresponding flow rate decreases, which increases the liquid sedimentation time and facilitates better separation of gas and liquid. The airflow with reduced flow rate will hit the outer wall of the speed reducer 23, and then enter the speed reducer 23, and then pass through the gradually shrinking and expanding flow area inside the speed reducer 23, so that the airflow will collide and coalesce during the circulation process, and combined with the vertical setting of the speed reducer 23, there is an inertial gravity sedimentation mode, so that the airflow is multiple separated, and the separation efficiency is improved. Gradual shrinkage and expansion refers to the change mode in which the inner diameter of the speed reducer 23 first becomes smaller and then becomes larger.
[0056] The structure of the speed reducer 23 can be seen in Figure 7 As shown in the figure, the internal gas flow direction is from bottom to top, and the flow area changes from small to large. Based on this feature, the internal fluid flow rate changes from fast to slow. As the fluid flow rate slows down, the separation effect of gas phase refrigerant and oil under gravity separation becomes more obvious, which can greatly improve the separation efficiency of the oil separator.
[0057] In some embodiments,
[0058] There are multiple speed reducing tubes 23 , and the multiple speed reducing tubes 23 are evenly distributed around the axis of the cylinder 1 .
[0059] A plurality of deceleration tubes 23 are provided to adjust the airflow flow area, thereby further adjusting the separation velocity of the airflow to meet actual needs and handle oil-gas separation under different flow velocity conditions. The plurality of deceleration tubes 23 are evenly arranged to avoid local airflow accumulation and improve the overall separation effect.
[0060] In some embodiments,
[0061] The oil separation assembly also includes an air guide device 21, which is provided with a plurality of second inlets and a second air outlet, each of the second inlets being connected to an outlet of the speed reducer 23, and the second air outlet being connected to the first air outlet 5; the air flow enters the air guide device 21 from the second inlet and is discharged from the air guide device 21 from the second air outlet.
[0062] When multiple speed reduction tubes 23 are provided, each speed reduction tube 23 can smoothly guide the airflow to the first air outlet 5. The present application adds an air guide device 21, and adopts multiple second inlets to connect with each speed reduction tube 23, and guides the outlet air of each speed reduction tube 23 to the first air outlet 5 through a second air outlet, thereby reducing the structure of connecting each speed reduction tube 23 with the first air outlet 5, making the structure inside the cylinder 1 simpler.
[0063] Since the air guide device 21 is provided with a plurality of second inlets and has only one second air outlet, the multiple air flows entering therein are bound to coalesce and collide, thereby improving the gas-liquid separation effect.
[0064] The specific structure of the air guide device 21 can be set to be claw-shaped, with a second inlet corresponding to the bottom of each claw, and a second air outlet is set above the center of the claw to guide the airflow.
[0065] In some embodiments,
[0066] The air guide device 21 is provided with a filter device 22, and the filter device 22 filters the airflow from the second inlet to the second outlet.
[0067] A filtering device 22 is further arranged on the air guide device 21 to filter the airflow from the second inlet to the second air outlet to ensure the cleanliness of the gas, and at the same time, separation of gas and liquid is achieved during the filtering process.
[0068] The filter device 22 is structurally arranged on the claw-shaped air guide device 21, and is arranged just below the second outlet. The inlet of the filter device 22 is connected to the second inlet, and the outlet is connected to the second air outlet.
[0069] In some embodiments,
[0070] The filtering device 22 includes a filtering chamber 221, an inner cylinder 222 and a filter element 223. The filtering chamber 221 is vertically arranged and has an oil hole 2211 at the bottom. The inner cylinder 222 is vertically arranged in the filtering chamber 221 and has a gap with the inner wall of the filtering chamber 221. The airflow enters the filtering chamber 221 through the gap, bypasses the bottom end of the inner cylinder 222, and then flows out from the inside of the inner cylinder 222 to the second air outlet. The filter element 223 fills the gap, or / and the filter element 223 covers the second air outlet.
[0071] The filter device 22 can specifically adopt a structure that increases the airflow path. For example, an inner cylinder 222 is set in the filter chamber 221. The inner cylinder 222 is a cylinder that is not sealed at the top and bottom. It functions to separate the gas flow path so that the airflow first enters the filter chamber 221 along the gap between the inner cylinder 222 and the inner wall of the filter chamber 221, and then flows out along the inside of the inner cylinder 222. A filter element 223 is set in the gap and / or the second air outlet to filter the airflow.
[0072] While the filter element 223 filters the airflow, it can also separate gas and liquid. An oil hole 2211 is provided at the bottom of the filter chamber 221 to facilitate the separated liquid to flow out of the oil hole 2211 into the cylinder 1.
[0073] The high-pressure gas discharged from the compressor contains lubricating oil, which is an oil-gas mixture. It enters the cylinder 1 through the first inlet 4. The gaseous refrigerant in the cylinder 1 flows downward until it enters the deceleration filter device 222 through the inlet of the deceleration tube 23. It is decelerated by the deceleration tube 23 in turn to expand the gravity sedimentation separation effect and the filtering separation of the filter element 223. Finally, the refrigerant gas is discharged from the first outlet 5.
[0074] Part of the lubricating oil adheres to the outer surface of the filter device 22 and slides down, part of the lubricating oil settles and drips from the speed reducer 23 , and another part of the lubricating oil settles and drips from the bottom of the filter bin 221 and gathers at the lower part of the cylinder 1 .
[0075] For filter element 223, if Figure 8 and 9 As shown, it is divided into an inner ring and an outer ring, which can filter the gas in the filter chamber 221 twice, and adjust the gas flow field under the partition of the inner cylinder 222 of the filter chamber 221 so that it finally flows upward and leaves the filter device 22.
[0076] The entire speed reduction filter device 222, such as Figure 3-6 As shown, its structure is that a filter chamber 221 is arranged in the middle to perform coalescence separation of the oil-gas mixture, and deceleration tubes 23 are arranged around to reduce the speed of the oil-gas mixture and realize gravity separation, and an air guide device 21 is used to guide the flow direction of the overall oil-gas mixture. The filter chamber 221 and the deceleration tube 23 are located at the same height in the cylinder 1, realizing multiple separations while improving space utilization.
[0077] In some embodiments,
[0078] The inner diameter of the flow path of the air flow between the second air outlet and the first air outlet 5 is set to gradually expand.
[0079] Since the diameter of the oil separator outlet is generally larger, while the diameter of the internal flow path is smaller, the second outlet diameter is smaller and the first outlet 5 diameter is larger, and a gradually expanding pipeline is used to connect to meet the normal connection between the oil separator internal pipeline and the oil separator external whole machine pipeline.
[0080] In some embodiments,
[0081] The first inlet 4 is higher than the inlet of the speed reducing tube 23 ; or / and, the cylinder 1 is a cylinder, and the first inlet 4 is arranged along the tangent direction of the cylinder 1 .
[0082] In this solution, the first inlet 4 is arranged at a position higher than the inlet of the speed reducing tube 23, so that the airflow entering the cylinder 1 needs to sink before entering the speed reducing tube 23, and in the process of the airflow sinking, the different sinking speeds of gas and liquid are utilized to facilitate separation; especially when the cylinder 1 is a cylinder and the first inlet 4 is arranged tangentially, the airflow enters the cylinder 1 in a spiral downward manner, and the effect of gas-liquid separation will be better. The airflow continuously hits the inner wall of the cylinder 1 in the spiral motion to achieve gas-liquid separation; after falling to the bottom, the gas rises and flows to the inlet of the speed reducing tube 23, and then is decelerated and filtered for separation.
[0083] In some embodiments,
[0084] The lower part of the cylinder 1 is set as an oil storage area, and the oil return port 6 is connected to the oil storage area; an oil baffle plate 3 is arranged above the oil storage area, the oil baffle plate 3 covers the oil storage area, and a through hole 31 is arranged on the oil baffle plate 3.
[0085] The gas-liquid separated liquid is collected in the lower part of the cylinder 1. Since the airflow entering the cylinder 1 is in a high-pressure state, it will enter at a high speed and impact the collected liquid, causing oil foam to be generated. In this scheme, an oil baffle plate 3 is added above the oil storage area where the liquid is collected, so that the oil-gas mixture entering first impacts the oil baffle plate 3. At this time, the oil droplets will be collected by the oil baffle plate 3 due to the collision effect. At the same time, a through hole 31 is provided on the oil baffle plate 3 to guide the collected oil droplets to the oil storage area below.
[0086] The presence of the oil baffle 3 can prevent the oil-gas mixture from directly impacting the liquid in the oil storage area, greatly reducing the generation of foam at the bottom of the oil.
[0087] According to another aspect of the present application, a compressor assembly is provided, comprising the oil separation assembly as described above; and further comprising a compressor, wherein the exhaust port of the compressor is connected to the first inlet 4 .
[0088] The first inlet 4 of the oil separation component is connected to the exhaust port of the compressor, so that the exhaust gas of the compressor is separated into gas and liquid in the oil separation component. A multiple separation structure is arranged in the cylinder 1 of the oil separation component, and the space utilization rate is high. At the same time, the multiple separation structure enables the high-pressure gas to be multiple separated by collision, filtration, aggregation and inertial gravity sedimentation, thereby improving the separation efficiency.
[0089] According to another aspect of the present application, an air conditioning system is provided, comprising the oil separation assembly as described above or the compressor assembly as described above.
[0090] For the air-conditioning system, the above-mentioned oil separation component or compressor component is used. The refrigerant discharged from the compressor will contain lubricating oil. The lubricating oil in the refrigerant can be effectively separated by the above-mentioned oil separation component, and the separation effect will not be affected by the fluctuation of the gas flow rate. In this way, it will not affect the COP of the refrigeration system, nor will it cause accidents such as false alarms and failures of the refrigeration system, and it may even cause the compressor to lack oil and be damaged.
[0091] It is easy for those skilled in the art to understand that the above-mentioned implementation modes can be freely combined and superimposed without conflict.
[0092] The above is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present application shall be included in the protection scope of the present application. The above is only a preferred implementation of the present application. It should be pointed out that for ordinary technicians in this technical field, several improvements and variations can be made without departing from the technical principles of the present application, and these improvements and variations should also be regarded as the protection scope of the present application.
