Description

Technical Field

[0001] The utility model belongs to the technical field of economizers, in particular to an economizer with high flexibility. Background Art

[0002] An economizer is a specialized heat exchanger primarily used in refrigeration systems to improve efficiency and performance. It absorbs heat through evaporation of the refrigerant itself, thereby subcooling the remaining refrigerant. This device is typically installed after the condenser and before the expansion valve of a refrigeration unit to ensure effective subcooling of the refrigerant before it reaches the evaporator.

[0003] In the prior art, economizer operation involves two cycles: a primary cycle and a secondary cycle. In the secondary cycle, the refrigerant originates from the medium-temperature, high-pressure refrigerant liquid condensed in the condenser. After throttling and cooling through the economizer's electronic expansion valve, it enters the secondary side of the economizer, where it absorbs heat from the refrigerant on the primary side and evaporates. It then enters the intermediate-pressure chamber of the compressor to participate in compression. In the primary cycle, the medium-temperature, high-pressure refrigerant liquid condensed in the condenser enters the primary side of the economizer. Heat is absorbed by the low-temperature, low-pressure refrigerant on the secondary side, further increasing its subcooling. After throttling through the system's electronic expansion valve, it enters the evaporator for absorption and evaporation, and then enters the compressor's suction chamber for compression.

[0004] During long-term use and observation, it was found that in the process of connecting the economizer to the expansion valve and compressor respectively, loose connections between the pipes will lead to a decrease in the refrigeration effect and affect the normal regulation of the expansion valve.

[0005] To this end, the utility model provides an economizer with high flexibility. Utility Model Content

[0006] In order to make up for the deficiencies of the prior art and solve at least one of the problems raised in the background art, an economizer with high flexibility is proposed.

[0007] The technical solution adopted by the present invention to solve its technical problems is as follows: the present invention is an economizer with high flexibility, including an economizer cylinder, an end of the economizer cylinder is equipped with a main road inlet, the other end of the economizer cylinder is equipped with a main road outlet, the economizer cylinder, the main road inlet and the main road outlet are connected, the middle of the side wall of the economizer cylinder is fixedly connected with an auxiliary road inlet, the middle of the side wall of the economizer cylinder is fixedly connected with an auxiliary road outlet, the economizer cylinder, the auxiliary road inlet and the auxiliary road outlet are connected, the middle of the side walls of the main road inlet and the main road outlet are both fixedly connected with airbags, one side of the airbag cover is arranged outside the main road inlet, the other side of the airbag cover is arranged outside the main road outlet, and a pair of airbags are equipped with a connecting rod. Tube, an air inlet pipe is fixedly connected to the middle of the airbag side wall on one side, the airbag, connecting pipe and air inlet pipe are all hollow and connected, and a movable component is provided in the middle of the side wall of the economizer cylinder. This step can connect the expansion valve and the compressor with the main road inlet, main road outlet, auxiliary road inlet and auxiliary road outlet tightly by arranging the airbag, connecting pipe and air inlet pipe, and the airbag device can adapt to pipe connections of different diameters and shapes, so that it can be flexibly used under various working conditions. At the same time, this arrangement can also effectively prevent the leakage of refrigerant or other working media, and prevent external impurities from entering the inside of the economizer cylinder, thereby maintaining the purity of the refrigerant, helping to reduce corrosion and blockage problems inside the system, and extending the service life of the system.

[0008] Preferably, the middle parts of the inner side walls of the main road inlet, main road outlet, auxiliary road inlet and auxiliary road outlet are all equipped with fixed plates, a pair of connecting rods are fixedly connected to the middle parts of the inner side walls of the fixed plates, the middle parts of the side walls of the connecting rods are rotatably connected to a rotating plate, and a torsion spring is provided between the rotating plate and the connecting rods. This step, by arranging the fixed plates, connecting rods and rotating plates, can prevent the refrigerant from flowing back into the economizer cylinder or other parts when the compressor stops working or the system pressure changes, and ensure that the refrigerant can only flow in the specified direction. The backflow of refrigerant will cause impact, wear or corrosion to the economizer cylinder, thereby reducing the service life and performance of the equipment. This setting can ensure that the refrigerant will not flow back into the equipment, thereby extending the service life of the equipment and improving its reliability.

[0009] Preferably, a drawstring is provided in the middle of the side wall of the airbag, and the drawstring is sleeved on the outside of the airbag. The middle of the drawstring side wall is slidably fitted with a limit block.

At the same time, this setting can maintain the stability and sealing of the airbag even in the case of high water pressure or water flow impact, and prevent moisture penetration.

[0010] Preferably, the middle part of the inner wall of the main road inlet, main road outlet, auxiliary road inlet and auxiliary road outlet are all equipped with sealing gaskets, and the sealing gaskets are made of elastic material. A plurality of convex pads are fixedly connected to the middle part of the side wall of the sealing gasket, and the convex pads are made of elastic material. By arranging the sealing gaskets and convex pads in this step, an effective seal can be formed between the two contacting pipes to prevent the leakage of refrigerant and maintain the integrity and stability of the system. In addition, this arrangement can further prevent external dust, moisture and other impurities from invading the interior of the economizer cylinder, thereby avoiding damage or malfunction of the equipment due to the intrusion of dust and moisture.

[0011] Preferably, the moving component includes a handle, which is fixed to the side wall of the economizer cylinder. A non-slip pad is fixed to the middle of the side wall of the handle, and the non-slip pad is made of elastic material.

[0012] Preferably, a flow meter is installed in the middle of the side wall of the economizer cylinder, and a temperature meter is installed in the middle of the side wall of the economizer cylinder. In this step, by setting the flow meter, the flow rate of the fluid inside the economizer cylinder can be accurately measured to ensure that the economizer cylinder can operate stably under various working conditions to avoid overload or underload. By setting the temperature tester, the temperature changes of the economizer cylinder and its surrounding environment can be monitored in real time to prevent performance degradation or damage caused by excessively high or low temperature.

[0013] Preferably, the economizer cylinder is made of a transparent material and is arranged between a pair of airbags. This step provides a transparent economizer cylinder, which can make its internal structure and operating status more clearly visible, helping staff to more intuitively understand the operating status of the economizer cylinder and promptly discover and deal with potential problems.

[0024] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] Specific examples are given below.

[0026] like Figures 1 to 4As shown, an economizer with high flexibility in an embodiment of the present invention includes an economizer cylinder 1, an end of the economizer cylinder 1 is equipped with a main road inlet 11, and the other end of the economizer cylinder 1 is equipped with a main road outlet 12, the economizer cylinder 1, the main road inlet 11 and the main road outlet 12 are connected, the middle of the side wall of the economizer cylinder 1 is fixedly connected to an auxiliary road inlet 13, the middle of the side wall of the economizer cylinder 1 is fixedly connected to an auxiliary road outlet 14, the economizer cylinder 1, the auxiliary road inlet 13 and the auxiliary road outlet 14 are connected, the middle of the side wall of the main road inlet 11 and the main road outlet 12 are fixedly connected with an air bag 15, and one side of the air bag 15 is covered by the main road inlet 1 1 outside, the other side air bag 15 cover is set outside the main road outlet 12, a connecting pipe 16 is installed between the pair of air bags 15, and an air inlet pipe 17 is fixed to the middle of the side wall of one side air bag 15. The air bag 15, the connecting pipe 16 and the air inlet pipe 17 are all hollow and connected. A moving component is set in the middle of the side wall of the economizer cylinder 1. When working, the staff uses the moving component to move the economizer cylinder 1 to the position where it needs to be installed, and then respectively connect the expansion valve and the compressor to the main road inlet 11, the main road outlet 12, the auxiliary road inlet 13 and the auxiliary road outlet 14. At this time, the refrigerant passes through the expansion valve and then passes through the auxiliary road inlet 13 enters the evaporation chamber in the economizer cylinder 1, then flows out from the auxiliary outlet 14 and enters the compressor. At the same time, another refrigerant enters the economizer cylinder 1 from the main inlet 11, and then flows out from the main outlet 12 and enters the expansion valve. After connecting them together, the staff will cover the airbag 15 at the pipe connection, and then connect the air inlet pipe 17 and the blower together. The air flow will enter the airbag 15 through the air inlet pipe 17. Because the airbag 15, the connecting pipe 16 and the air inlet pipe 17 are connected, the air flow will circulate inside the airbag 15 and the connecting pipe 16, causing the airbag 15 to expand and connect the pipes. The expansion valve and the compressor are tightly connected to the main inlet 11, the main outlet 12, the auxiliary inlet 13 and the auxiliary outlet 14 by arranging the air bag 15, the connecting pipe 16 and the air inlet pipe 17. The air bag 15 can adapt to pipe connections of different diameters and shapes, so that it can be flexibly used under various working conditions. At the same time, this arrangement can also effectively prevent the leakage of refrigerant or other working media and prevent external impurities from entering the interior of the economizer cylinder 1, thereby maintaining the purity of the refrigerant, helping to reduce corrosion and blockage problems inside the system and extending the service life of the system.

[0027] like Figure 1 and Figure 4As shown, the middle of the inner wall of the main road entrance 11, the main road exit 12, the auxiliary road entrance 13 and the auxiliary road exit 14 is equipped with a fixed plate 2, and a pair of connecting rods 21 is fixedly connected to the middle of the inner wall of the fixed plate 2. The middle of the side wall of the connecting rod 21 is rotatably connected with a rotating plate 22. A torsion spring is arranged between the rotating plate 22 and the connecting rod 21. When the refrigerant flows between the economizer cylinder body 1, the main road entrance 11, the main road exit 12, the auxiliary road entrance 13 and the auxiliary road exit 14 during work, the refrigerant will give the rotating plate 22 an impact force, so that the rotating plate 22 rotates in the middle of the connecting rod 21. Because a torsion spring is arranged between the rotating plate 22 and the connecting rod 21, the rotating plate 22 will only rotate in one direction at this time. This step can prevent the reverse flow of refrigerant back into the economizer cylinder body 1 or other parts when the compressor stops working or the system pressure changes, ensuring that the refrigerant can only flow in the specified direction. The reverse flow of refrigerant will cause impact, wear or corrosion to the economizer cylinder body 1, thereby reducing the service life and performance of the equipment. This setting can ensure that the refrigerant will not flow back into the equipment, thereby prolonging the service life of the equipment and improving its reliability.

[0028] As shown in Figures 1 to 3 The middle of the side wall of the air bag 15 is provided with a pull rope 3, and the pull rope 3 is sleeved outside the air bag 15. The middle of the side wall of the pull rope 3 is slidingly fitted with a limiting block 31. When the air bag 15 is arranged at the connection between the expansion valve and the compressor and the main road entrance 11, the main road exit 12, the auxiliary road entrance 13 and the auxiliary road exit 14 during work, the workers use multiple pull ropes 3 to pull the air bag 15 from the outside, and then use the limiting block 31 to fix the pull rope 3, so that the air bag 15 is tightly attached to the pipe connection. This step can make the air bag 15 tightly attached to the pipe connection, reduce the existence of gaps and voids, and improve the sealing performance. At the same time, even in the case of large water pressure or water flow impact, the air bag 15 can still maintain stability and sealing performance, preventing water penetration.

[0029] As shown in Figure 2 and Figure 4As shown, the middle part of the inner wall of the main inlet 11, the main outlet 12, the auxiliary inlet 13 and the auxiliary outlet 14 are all equipped with a sealing gasket 4, which is made of elastic material. A plurality of convex pads 41 are fixedly connected to the middle part of the side wall of the sealing gasket 4, which is made of elastic material. During operation, when the expansion valve and the compressor are threadedly connected to the main inlet 11, the main outlet 12, the auxiliary inlet 13 and the auxiliary outlet 14 respectively, the pipes of the expansion valve and the compressor will contact the sealing gasket 4. At this time, the sealing gasket 4 and the convex pad 41 will deform and seal the contact area. In this step, by arranging the sealing gasket 4 and the convex pad 41, an effective seal can be formed between the two contacting pipes to prevent leakage of refrigerant and maintain the integrity and stability of the system. In addition, this arrangement can further prevent external dust, moisture and other impurities from invading the interior of the economizer cylinder 1, thereby avoiding damage or malfunction of the equipment due to the intrusion of dust and moisture.

[0030] like Figure 1 and Figure 2 As shown, the moving assembly includes a handle 5, which is fixed to the side wall of the economizer cylinder 1. An anti-slip pad 51 is fixed to the middle of the side wall of the handle 5. The anti-slip pad 51 is made of elastic material. This step provides a convenient fulcrum for the staff by setting the handle 5, making the movement, adjustment or operation of the economizer cylinder 1 easier and more labor-saving. The anti-slip pad 51 can reduce the friction and discomfort between the staff's hands and the handle 5.

[0031] like Figure 1 and Figure 2 As shown, a flow meter 6 is installed in the middle of the side wall of the economizer cylinder 1, and a temperature meter 61 is installed in the middle of the side wall of the economizer cylinder 1. In this step, by setting the flow meter 6, the flow rate of the fluid inside the economizer cylinder 1 can be accurately measured to ensure that the economizer cylinder 1 can operate stably under various working conditions to avoid overload or underload. By setting the temperature meter 61, the temperature changes of the economizer cylinder 1 and its surrounding environment can be monitored in real time to prevent performance degradation or damage due to excessively high or low temperature.

[0032] like Figure 1 and Figure 2 As shown, the economizer cylinder 1 is made of a transparent material and is arranged between a pair of airbags 15. This step makes the internal structure and operating status of the economizer cylinder 1 more clearly visible by providing a transparent economizer cylinder 1, which helps the staff to more intuitively understand the operating status of the economizer cylinder 1 and promptly discover and deal with potential problems.

[0033] Working principle: The staff uses the moving assembly to move the economizer cylinder 1 to the position where it needs to be installed, and then respectively connects the expansion valve and the compressor to the main inlet 11, the main outlet 12, the auxiliary inlet 13 and the auxiliary outlet 14. At this time, the refrigerant passes through the expansion valve and then enters the evaporation chamber in the economizer cylinder 1 through the auxiliary inlet 13, and then flows out from the auxiliary outlet 14 and enters the compressor. At the same time, another refrigerant enters the economizer cylinder 1 from the main inlet 11, and then flows out from the main outlet 12 and enters the expansion valve. After connecting them together, the staff sets the air bag 15 cover at the pipe connection, and then connects the air inlet pipe 17 and the blower together. The airflow will enter the air bag 15 through the air inlet pipe 17. Because the air bag 15, the connecting pipe 16 and the air inlet pipe 17 are connected, the airflow will circulate inside the air bag 15 and the connecting pipe 16, causing the air bag 15 to expand and seal the pipe connection together. When the refrigerant When the refrigerant flows between the economizer cylinder 1, the main road inlet 11, the main road outlet 12, the auxiliary road inlet 13 and the auxiliary road outlet 14, the refrigerant will give the rotating plate 22 an impact force, causing the rotating plate 22 to rotate in the middle of the connecting rod 21. Because a torsion spring is provided between the rotating plate 22 and the connecting rod 21, the rotating plate 22 will only rotate in one direction at this time. When the air bag 15 cover is arranged at the connection between the expansion valve and the compressor and the main road inlet 11, the main road outlet 12, the auxiliary road inlet 13 and the auxiliary road outlet 14, the staff uses multiple pull ropes 3 to tighten the air bag 15 from the outside, and then uses the limit block 31 to fix the pull rope 3 so that the air bag 15 fits tightly at the pipe connection. When the expansion valve and the compressor are threadedly connected to the main road inlet 11, the main road outlet 12, the auxiliary road inlet 13 and the auxiliary road outlet 14 respectively, the pipes of the expansion valve and the compressor will contact the sealing gasket 4. At this time, the sealing gasket 4 and the convex gasket 41 will deform to seal the contact area.

[0034] The above shows and describes the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention.
