Abstract
Description
Technical Field
[0001] This utility model relates to the field of refrigeration equipment technology, specifically to an oil separation device, a condenser, and a refrigeration system. Background Technology
[0002] In the field of refrigeration equipment, existing screw chillers and heat pump units are widely used in industrial cooling, central air conditioning, and heating due to their stable performance and high energy efficiency. Their accompanying oil separators, as key components ensuring the normal operation of the refrigeration system, primarily function to separate the refrigerant from the lubricating oil, preventing lubricating oil from entering the system and affecting refrigeration efficiency, while simultaneously recovering the lubricating oil to maintain proper compressor lubrication.
[0003] With the development of refrigeration and heat pump technologies, large-capacity chillers or heat pump units that still use traditional oil separators for oil-gas separation need to have their dimensions increased to meet oil separation performance targets under high refrigerant flow rates. However, simply enlarging the size of traditional oil separators to meet heating capacity requirements not only significantly increases the outer diameter of the casing, making the overall size of the chiller unit too large, which is detrimental to installation and space layout, but also significantly increases production costs. Furthermore, the internal flow channel design and structure of traditional oil separators make it difficult to ensure that the refrigerant gas velocity meets standards when large refrigerant flows through, thus failing to achieve efficient oil-gas separation and directly affecting the operating efficiency and stability of the chiller.

Detailed Implementation
[0036] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0037] For refrigeration systems with high heating capacity, one or more embodiments provide an oil separation device 100 disposed in the condenser 200. Before the high-temperature, high-pressure refrigerant gas discharged from the compressor is condensed into a medium-temperature, high-pressure refrigerant liquid, the oil separation device 100 provided in one or more embodiments separates the compressor lubricating oil entrained in the refrigerant gas, and meets the oil separation performance target under high heating capacity, thereby ensuring the stability and efficiency of the subsequent condensation process.
[0038] Figure 1 This is a front view of the structure of a condenser 200 having an oil separation device 100 in one or more embodiments. Figure 2 This is a structural cross-sectional view of a condenser 200 having an oil separation device 100 in one or more embodiments. (In conjunction with...) Figure 1 , Figure 2 As shown, in one or more embodiments, the condenser 200 is formed by a cylindrical housing 201, and the oil separator 100 is disposed in a receiving cavity 202 inside the housing 201.
[0039] To enhance the oil separation effect, in one or more embodiments, the oil separation device 100 is provided with a top plate 1 and an oil separation baffle 2, as shown in the reference. Figure 1 and Figure 2 The top plate 1 is disposed inside the housing 201 in a form that matches the shape of the inner wall of the housing 201. The oil separation baffle 2 extends along the length of the housing 201 and is disposed inside the housing 201, with its edge in the length direction connected to the top plate 1. The oil separation baffle 2 and the top plate 1 enclose the oil separation chamber 3 inside the oil separation device 100. In the receiving cavity 202 of the housing 201, after removing the space occupied by the oil separation chamber 3, the remaining part is the condensation chamber 203. By arranging several heat exchange tubes (not shown in the figure) in the condensation chamber 203, the refrigerant gas after oil separation is condensed into liquid.
[0040] Figure 3 This is a structural front view of an oil separation device in one or more embodiments. Figure 4 This is a structural perspective view of an oil separation device in one or more embodiments. For example... Figure 3 and Figure 4 As shown, the oil separator 100 includes a first refrigerant inlet 41, a second refrigerant inlet 42, and a third refrigerant inlet 43, all opening onto the portion of the top plate 1 corresponding to the oil separation chamber 3. They also have corresponding openings on the housing 201, used to introduce the high-temperature, high-pressure refrigerant mixture from the compressor into the oil separation chamber 3. The oil separator 100 also includes a first refrigerant outlet 51, a second refrigerant outlet 52, a third refrigerant outlet 53, and a fourth refrigerant outlet 54, sequentially opening along the length of the oil separation partition 2, used to discharge the gaseous refrigerant separated from the lubricating oil from the oil separation chamber 3 into the condensation chamber 203. (Reference) Figure 4 The first refrigerant inlet 41 is located between the first refrigerant outlet 51 and the second refrigerant outlet 52. The second refrigerant inlet 42 is located between the second refrigerant outlet 52 and the third refrigerant outlet 53. The third refrigerant inlet 43 is located between the third refrigerant outlet 53 and the fourth refrigerant outlet 54.
[0041] Taking the refrigerant mixture gas being introduced into the oil separation chamber 3 of the oil separation device 100 provided in one or more embodiments through the first refrigerant inlet 41 as an example, after entering, the refrigerant mixture gas is evenly divided into two streams, which continue to flow towards both ends along the length of the oil separation chamber 3 until they flow to the adjacent first refrigerant outlet 51 and second refrigerant outlet 52 on the left and right sides. During the flow of the mixture gas in the oil separation chamber 3, tiny lubricating oil droplets carried in the airflow adhere to the inner wall surface of the oil separation chamber 3 or settle by weight onto the surface of the oil separation partition 2. Finally, the refrigerant gas that has achieved the oil separation target flows from the oil separation chamber 3 to the condensation chamber 203 through the first refrigerant outlet 51 and the second refrigerant outlet 52.
[0042] In one or more embodiments, since the oil separator 100 is provided with a first refrigerant inlet 41, a second refrigerant inlet 42, and a third refrigerant inlet 43, the refrigerant mixture entering the oil separator 3 is divided into six streams. Specifically, two streams branching off from the first refrigerant inlet 41 along the length of the oil separator 3 flow to the first refrigerant outlet 51 and the second refrigerant outlet 52, respectively; two streams branching off from the second refrigerant inlet 42 along the length of the oil separator 3 flow to the second refrigerant outlet 52 and the third refrigerant outlet 53, respectively; and two streams branching off from the third refrigerant inlet 43 along the length of the oil separator 3 flow to the third refrigerant outlet 53 and the fourth refrigerant outlet 54, respectively. Through the above stream division design, the flow velocity of the refrigerant stream entering the oil separator 3 can be greatly reduced. In some refrigeration systems, when the compressor has a high heating capacity, the oil separator 100 provided in one or more embodiments can effectively reduce the flow rate of the high-speed refrigerant gas discharged from the compressor with high heating capacity, ensuring that the refrigerant gas flow rate in the oil separation chamber 3 is always kept below the specified flow rate. This guarantees that the refrigerant gas has sufficient residence time after entering the oil separator 100, thereby achieving good oil separation performance under high heating capacity. Simultaneously, it also ensures that the refrigerant mixture enters the oil separation chamber 3 fully and uniformly, allowing for more rational and effective utilization of the internal space of the oil separation chamber 3. This avoids the problem of arbitrarily increasing the size of the oil separator 100, or even the condenser 200, due to the increased oil separation target, which would necessitate re-matching with other devices in the refrigeration system and lead to increased overall equipment size and production costs. In some applications with lower heating capacity, the oil separator 100 provided in one or more embodiments can also reduce the size of the oil separator 100 itself or the condenser 200 while ensuring oil separation performance, thus facilitating equipment installation and use.
[0043] To ensure that the space within the oil separation chamber 3 can be fully utilized, allowing the refrigerant gas flow from the compressor to the oil separation device 100 to have a longer flow path and residence time within the oil separation chamber 3, thereby achieving the separation target of refrigerant gas and oil droplets, in one or more embodiments, the first refrigerant outlet 51 is located at one end of the oil separation baffle 2 along its length, and the second refrigerant outlet 52 is located at the other end of the oil separation baffle 2 along its length.
[0044] After the refrigerant mixture enters the oil separator 100, the oil droplets carried in the gas flow and the lubricating oil adhering to the inner wall of the oil separation chamber 3 will gradually settle under their own gravity until they fall onto the surface of the oil separation baffle 2 inside the oil separation chamber 3. To prevent oil droplets from being secondary washed by the refrigerant gas flow along the oil separation baffle 2 and directly entering the refrigerant outlet, causing lubricating oil to enter the condenser chamber 203 or other equipment in the refrigeration system, thereby affecting the oil separation performance of the oil separator 100 and the heat exchange performance of the condenser 200, and even affecting the normal operation of the entire refrigeration system, in one or more embodiments, the oil separator 100 is also provided with an outlet cover 6, which is respectively arranged in the oil separation chamber 3 in the form of surrounding the first refrigerant outlet 51 and / or the second refrigerant outlet 52 and / or the third refrigerant outlet 53 and / or the fourth refrigerant outlet 54. The outlet cover 6 effectively prevents oil droplets from being blown into the refrigerant outlet by the refrigerant airflow along the oil separation baffle 2, thus ensuring the oil separation effect. To ensure that the refrigerant gas entering the condensing chamber 203 via the first refrigerant outlet 51, the second refrigerant outlet 52, the third refrigerant outlet 53, and the fourth refrigerant outlet 54 enters the condensing chamber at a specific angle, reference is made... Figure 4 The outlet cover 6 is set perpendicular to the oil separator 2 in the form of surrounding the refrigerant outlet, so as to prevent the refrigerant gas from directly impacting the first refrigerant outlet 51, the second refrigerant outlet 52, the third refrigerant outlet 53 and the fourth refrigerant outlet 54. The upper edge of the outlet cover 6 is inclined to the oil separator 2, that is, the height of the outlet cover 6 perpendicular to the oil separator 2 gradually increases in the direction towards the center of the oil separator 2, so that the distance between the upper edge of the outlet cover 6 and the housing 2 is approximately the same, thereby realizing the angle adjustment of the refrigerant gas entering the condensation chamber 203.
[0045] refer to Figure 2 and Figure 4The oil separator 100 provided in one or more embodiments further includes filter screens 7, which are respectively disposed between the first refrigerant inlet 41 and the first refrigerant outlet 51, between the first refrigerant inlet 41 and the second refrigerant outlet 52, between the second refrigerant outlet 52 and the second refrigerant inlet 42, between the second refrigerant inlet 42 and the third refrigerant outlet 53, between the third refrigerant outlet 53 and the third refrigerant inlet 43, and between the third refrigerant inlet 43 and the fourth refrigerant outlet 54, in a form perpendicular to the length direction of the oil separator 2. In one or more embodiments, after the refrigerant mixture gas discharged from the compressor enters the oil separator 100, the six evenly separated refrigerant gas streams will pass through the filter screens 7 on the left and right sides of the first refrigerant outlet 51, the second refrigerant outlet 52, and the third refrigerant outlet 53, respectively. Taking the process of refrigerant gas flow entering the oil separation chamber 3 from the first refrigerant inlet 41 as an example, the refrigerant mixture entering the oil separation chamber 3 from the first refrigerant inlet 41 is divided into two streams, flowing towards both ends of the length direction of the oil separation chamber 3, until the two streams come into contact with the filter screens 7 on the left and right sides of the first refrigerant inlet 41, respectively. The refrigerant gas in the stream will pass through the gaps in the filter screen 7 and flow to the first refrigerant outlet 51 and the second refrigerant outlet 52, respectively. The oil droplets carried in the stream will be intercepted by the filter screen 7 and remain on the surface of the filter screen 7. After a period of time, the small oil droplets intercepted by the filter screen 7 will accumulate, and the larger oil droplets formed will fall down along the filter screen 7 to the bottom of the oil separation chamber 3 under the action of gravity, thereby completing the separation of some oil droplets from the refrigerant gas. In one or more embodiments, the filter screen 7 is semi-cylindrical, and the circular cross-sectional shape of the semi-cylindrical part is the same as the cross-sectional shape perpendicular to the length direction of the oil separation chamber 3. The filter screen 7 can be made of wire mesh and has multiple filter holes. In one or more embodiments, the material and pore size of the filter screen 7 can be selected according to the specific application scenario and oil separation target, and no specific limitations are imposed here.
[0046] To enable the oil separator 100 to continuously separate lubricating oil entrained in the refrigerant mixture discharged from the compressor and maintain a normal supply of lubricating oil within the compressor, in one or more embodiments, the oil separator 100 further includes multiple oil outlets 8. (Reference) Figure 2 and Figure 4The oil separator 100 has four oil outlets 8, each located on the other side of the oil separation baffle 2 opposite the first refrigerant outlet 51 and / or the second refrigerant outlet 52 and / or the third refrigerant outlet 53 and / or the fourth refrigerant outlet 54. The four oil outlets 8 have the same cross-sectional size and shape. In other embodiments, the cross-sectional size and shape of each oil outlet 8 can be independently designed based on the actual oil separation effect of the oil separator 100 and the distribution of lubricating oil within the oil separation chamber 3; no specific limitations are imposed here. As the oil separator 100 continuously separates the lubricating oil entrained in the refrigerant gas, the oil droplets adhering to the inner wall of the oil separation chamber 3 and the surface of the filter screen 7 will gradually settle to the bottom of the oil separation chamber 3. Once the collected lubricating oil at the bottom reaches a certain level, it will be discharged from the oil separation chamber 3 through the oil outlets 8 to the return oil pipe (not shown in the figure), and finally flow back to the compressor (not shown in the figure), ensuring the balance between compressor lubrication and system circulation.
[0047] In one or more embodiments, the oil separator 100 further includes two end baffles 9, see reference. Figure 4 Two end baffles 9 are respectively disposed at both ends of the oil separation baffle 2 along its length and are connected to the top plate 1 and the oil separation baffle 2.
[0048] For ease of manufacturing and to ensure that the flow rates and velocities of the six streams of air separated within the oil separation chamber 3 are kept as balanced as possible, thereby guaranteeing the stability and efficiency of the oil separation performance of the oil separation device 100, in one or more embodiments, the first refrigerant inlet 41, the second refrigerant inlet 42, and the third refrigerant inlet 43 have the same cross-sectional size and shape; the first refrigerant outlet 51 and the fourth refrigerant outlet 54 have the same cross-sectional size and shape; and the second refrigerant outlet 52 and the third refrigerant outlet 53 have the same cross-sectional size and shape. (Reference) Figure 4When the oil separator 100 is running, the oil separation chamber 3 contains six refrigerant airflows with approximately the same flow rate and velocity. The first refrigerant outlet 51 and the fourth refrigerant outlet 54 are respectively fed by one airflow branched off from the first refrigerant inlet 41 and the third refrigerant inlet 43. The second refrigerant outlet 52 is fed by two airflows branched off from the first refrigerant inlet 41 and the second refrigerant inlet 42. The third refrigerant outlet 53 is fed by two airflows branched off from the second refrigerant inlet 42 and the third refrigerant inlet 43. Since the gas flow rates through the second refrigerant outlet 52 and the third refrigerant outlet 53 are approximately twice those of the first refrigerant outlet 51 and the fourth refrigerant outlet 54, the cross-sectional areas of the second refrigerant outlet 52 and the third refrigerant outlet 53 are approximately twice those of the first refrigerant outlet 51 and the fourth refrigerant outlet 54. This ensures that the flow rates of the refrigerant gas entering the condensing chamber 203 from the first refrigerant outlet 51, the second refrigerant outlet 52, the third refrigerant outlet 53, and the fourth refrigerant outlet 54 are approximately the same, thereby further ensuring the stability and efficiency of the condenser 200 in condensing the refrigerant gas entering the condensing chamber 203 into a liquid.
[0049] In one or more embodiments, the first refrigerant inlet 41 and the third refrigerant inlet 43 are symmetrically arranged about the midpoint of the length direction of the oil separation chamber 3, and the second refrigerant inlet 42 is located between the first refrigerant inlet 41 and the third refrigerant inlet 43; the first refrigerant outlet 51 and the second refrigerant outlet 52 are symmetrically arranged with the third refrigerant outlet 53 and the fourth refrigerant outlet 54 about the midpoint of the length direction of the oil separation chamber 3. Through the above embodiments, the flow velocity of the six airflows in the oil separation chamber 3 can be made more uniform and the oil separation target can be better achieved.
[0050] In one or more embodiments, the oil separator 100 further includes a diversion pipe 10, as shown in the reference. Figure 3The distribution pipe 10 is arranged parallel to the oil separation chamber 3. Three distribution ports are located near both ends and the middle of the distribution pipe 10, respectively. These ports are connected to the first refrigerant inlet 41, the second refrigerant inlet 42, and the third refrigerant inlet 43. In one or more embodiments, the two ends of the distribution pipe 10 can be connected to two exhaust pipes branching off from the same compressor, or they can be connected to the exhaust pipes of two different compressors. The flow rate and velocity of the refrigerant mixture entering the two ends of the distribution pipe 10 from the exhaust pipes are basically the same, ensuring that the refrigerant mixture is evenly distributed among the three distribution ports after entering the distribution pipe 10. The mixture is then fed into the oil separation chamber 3 through these ports, thus ensuring a uniform distribution of the refrigerant mixture within the oil separation chamber 3 for better oil-gas separation. In addition, the first refrigerant inlet 41 and the third refrigerant inlet 43 are symmetrically arranged about the midpoint of the length direction of the oil separation chamber 3, and the second refrigerant inlet 42 is located between the first refrigerant inlet 41 and the third refrigerant inlet 43. The first refrigerant outlet 51 and the second refrigerant outlet 52 are symmetrically arranged about the midpoint of the length direction of the oil separation chamber 3, along with the third refrigerant outlet 53 and the fourth refrigerant outlet 54.
[0051] Furthermore, although the above embodiments are illustrated by the example of an oil separation device 100 including a top plate 1 and an oil separation partition 2, with the top plate 1 matching the shape of the inner wall of the housing 201, it is not limited to this. In the case of not providing a top plate 1, but using a portion of the housing 201 to enclose the oil separation partition 2 to form an oil separation chamber 3, it also falls within the protection scope of this application.
[0052] In one or more embodiments, a condenser 200 is also provided, see reference. Figure 1 and Figure 2 The condenser 200 includes a housing 201 and an oil separator 100. After removing the space occupied by the oil separator 100 in the housing 201, the oil separator 2 forms a condensation chamber 203 in the housing 201.
[0053] In order to allow the separated lubricating oil to settle to the bottom of the oil separation chamber 3 as quickly as possible and to flow back to the compressor from the oil outlet 8 as much as possible, in one or more embodiments, when the oil separation device 100 is installed in the housing 201, the angle between the oil separation baffle 2 and the horizontal installation surface of the housing 201 is between 0° and 90°.
[0054] In one or more embodiments, a refrigeration system is also provided, including a compressor, a condenser, an expansion valve and an evaporator connected in sequence via refrigerant pipes, wherein the condenser of the refrigeration system is the condenser 200 of one or more of the above embodiments.
[0055] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
