[0002] The air conditioning receiver is a key metal container in the refrigeration system, usually located between the condenser and the throttling device. It is used to store liquid refrigerant from the condenser, absorb excess liquid refrigerant when the system operating conditions change, or replenish the supply when needed, to ensure stable flow and maintain the efficient and stable operation of the air conditioning system.

[0003] In the prior art, such as Chinese Publication No. CN211177537U, this utility model discloses a liquid receiver and an air conditioner. The liquid receiver includes: an outer shell with an external inlet and an external outlet; an inner shell disposed within the outer shell, the inner shell having an internal inlet, an internal outlet, and an inner cavity connecting the internal inlet and the internal outlet, the internal inlet and the internal outlet extending out of the outer shell; an outer cavity is formed between the inner shell and the outer shell to allow heat exchange between the inner cavity and the outer cavity through the inner shell, the outer cavity connecting the external inlet and the external outlet. This utility model's liquid receiver allows the refrigerant to fully exchange heat using the liquid receiver as a medium during circulation, improving the refrigerant's heat exchange efficiency and thus increasing energy utilization.

[0034] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0035] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0036] Example 1, such as Figures 1 to 4As shown, this utility model provides a replaceable air conditioner liquid receiver filter, including a liquid receiver tank 1. A lower cover plate 6 is movably connected to the bottom outer surface of the liquid receiver tank 1. Multiple mounting brackets 18 are movably snapped onto the bottom inner surface of the lower cover plate 6. The lower cover plate 6 and the multiple mounting brackets 18 are slidably and sealingly connected to the bottom inner surface of the liquid receiver tank 1. A filter screen 16 is fixedly installed on the top outer surface of the multiple mounting brackets 18. A sliding sealing sleeve 17 is fixedly inserted through the inner surface of the filter screen 16. A disassembly and assembly assembly is provided on the lower cover plate 6. An upper cover plate 2 is fixedly installed on the top outer surface of the liquid receiver tank 1. A liquid receiver assembly is installed on the upper cover plate 2. The disassembly and assembly assembly includes two lower connecting plates 9. All connecting plates 9 are fixedly installed on the outer surface of the lower cover plate 6. Two upper connecting plates 14 are fixedly installed on the outer surface of the liquid storage tank 1. The inner surfaces of the two upper connecting plates 14 are threaded with fastening bolts 12. The two fastening bolts 12 are respectively threaded to the inner surfaces of the two lower connecting plates 9. The outer surfaces of the two fastening bolts 12 are threaded with nuts 13. The liquid inlet pipe 15 continuously injects liquid refrigerant into the bottom of the liquid storage tank 1, causing the liquid refrigerant level in the liquid storage tank 1 to rise. When the liquid refrigerant level rises to contact the filter screen 16, the filter screen 16 filters out metal shavings generated by compressor wear, welding residual oxide scale, corrosion products falling off the pipeline, and insulation material fragments in the liquid refrigerant. The filtration process prevents metal shavings from compressor wear, welding residue, corrosion products from pipes, and insulation material fragments from entering the reservoir tank 1 and the upper outlet pipe 11. The sliding sealing sleeve 17 ensures the sealing and stability of the connection between the inlet pipe 15 and the filter screen 16. By rotating the two fastening bolts 12, the two nuts 13 are separated from the two fastening bolts 12, releasing the fastening connection between the lower connecting plates 9 and the upper connecting plates 14 on both sides. This also releases the fastening connection between the reservoir tank 1 and the lower cover plate 6. The reservoir tank 1 is then removed from the inner surface of the lower cover plate 6. The multiple mounting brackets 18 and the filter screen 16 that are movably attached to the inner surface of the lower cover plate 6 are then removed. It can clean and remove metal shavings, welding residue oxide scale, corrosion products and insulation material fragments generated by compressor wear, which are filtered and deposited in the filter screen 16 and the lower cover plate 6 after being filtered and screened. The cleaned or new filter screen 16 is installed inside the lower cover plate 6 by multiple mounting brackets 18. The liquid storage tank 1 is connected to the lower cover plate 6 and then fastened by the upper connecting plates 14 on both sides and the lower connecting plates 9 on both sides, with two fastening bolts 12 and two nuts 13. This completes the convenient disassembly, replacement and cleaning of the filter screen 16 in the liquid storage tank 1, so that impurities in the liquid refrigerant can be effectively intercepted, improving the reliability and service life of the equipment.

[0037] Example 2, as Figures 1 to 4As shown, the liquid storage assembly includes two sealing gaskets 4, which are fixedly installed on the inner surface of the top of the upper cover plate 2. An inlet pipe 15 is fixedly installed on the inner surface of one sealing gasket 4, and the inlet pipe 15 is slidably sealed to the sliding sealing sleeve 17. An outlet pipe 11 is fixedly installed on the inner surface of the other sealing gasket 4. High-pressure liquid refrigerant output from the external condenser enters the liquid storage tank 1 through the inlet pipe 15 and the upper cover plate 2. Because the inlet pipe 15 extends close to the bottom of the liquid storage tank 1, the liquid refrigerant... The refrigerant is released from the inlet pipe 15 near the bottom of the liquid receiver tank 1. Due to gravity and reduced flow rate, the liquid refrigerant settles and accumulates at the bottom of the liquid receiver tank 1. When the liquid level of the liquid refrigerant continues to rise and submerges the inlet of the outlet pipe 11, the liquid refrigerant is forced out through the outlet pipe 11 and flows to the expansion device, ensuring a stable flow of liquid refrigerant and maintaining the efficient and stable operation of the air conditioning system. The two sealing gaskets 4 improve the sealing and stability of the connection between the upper cover plate 2 and the inlet pipe 15 and the outlet pipe 11.

[0038] Furthermore, such as Figures 1 to 4 As shown, a fixed flange 3 is fixedly installed on the outer surface of one end of the inlet pipe 15 and the outlet pipe 11. The two fixed flanges 3 are respectively connected to the inner surface of the inlet pipe 15 and the outlet pipe 11. The inlet pipe 15 and the outlet pipe 11 are fastened and connected to the external system pipeline through the two fixed flanges 3.

[0039] Furthermore, such as Figures 1 to 4 As shown, rubber gaskets 5 are fixedly installed on the outer surfaces of both fixed flanges 3, and multiple screw holes are opened on the outer surfaces of both fixed flanges 3. The two rubber gaskets 5 improve the sealing performance of the connection between the two fixed flanges 3 and the external connection mechanism, and the two fixed flanges 3 are fastened through the multiple screw holes.

[0040] Furthermore, such as Figures 1 to 4 As shown, two support plates 7 are fixedly installed on the bottom outer surface of the lower cover plate 6, and a base plate 8 is fixedly installed on the bottom outer surface of the two support plates 7. The two support plates 7, together with the base plate 8, provide stable support for the main body of the device.

[0041] Furthermore, such as Figures 1 to 4 As shown, two positioning grooves 10 are provided on the outer surface of the base plate 8. The two positioning grooves 10 are symmetrically arranged on the outer surface of the base plate 8. The two positioning grooves 10 cooperate with the external positioning and installation mechanism to position and install the base plate 8.

[0042] Working principle: High-pressure liquid refrigerant from the external condenser enters the receiver tank 1 through the inlet pipe 15 and the upper cover plate 2. Since the inlet pipe 15 extends close to the bottom of the receiver tank 1, the liquid refrigerant is released from the inlet pipe 15 near the bottom of the receiver tank 1. Due to gravity and reduced flow velocity, the liquid refrigerant settles and accumulates at the bottom of the receiver tank 1. At this point, the liquid refrigerant contains metal shavings from compressor wear, residual oxide scale from welding, corrosion products from detached pipes, and fragments of insulating material. The inlet pipe 15 continuously injects liquid refrigerant into the bottom of the receiver tank 1. This causes the liquid refrigerant level in the receiver tank 1 to rise. When the liquid refrigerant level rises to contact the filter screen 16, the filter screen 16 filters and screens out metal debris from compressor wear, welding residue oxide scale, corrosion products from pipelines, and insulation material fragments from the liquid refrigerant. This prevents these materials from entering the receiver tank 1 and the upper outlet pipe 11. The sliding sealing sleeve 17 ensures the sealing and stability of the connection between the inlet pipe 15 and the filter screen 16. The liquid refrigerant level continues to rise and submerge... When there is no liquid outlet pipe 11 inlet, the liquid refrigerant is forced out through the liquid outlet pipe 11 and flows to the expansion device, ensuring a stable liquid refrigerant flow and maintaining the efficient and stable operation of the air conditioning system. Rotate the two fastening bolts 12 to separate the two nuts 13 from the two fastening bolts 12, releasing the fastening connection between the lower connecting plates 9 on both sides and the upper connecting plates 14 on both sides, and releasing the fastening connection between the liquid receiver tank 1 and the lower cover plate 6. Remove the liquid receiver tank 1 from the inner surface of the lower cover plate 6, and remove the multiple mounting brackets 18 and the filter screen 16 that are movably clipped to the inner surface of the lower cover plate 6. The liquid receiver tank 1 can be filtered and screened by the filter screen 16 and deposited on the filter screen 16. The filter screen 16 is cleaned and removed from the compressor wear in the lower cover plate 6, including metal shavings, welding residue, corrosion products from the pipeline, and insulation material fragments. The cleaned or new filter screen 16 is then installed inside the lower cover plate 6 using multiple mounting brackets 18. The liquid storage tank 1 is then connected to the lower cover plate 6 and secured using the upper connecting plates 14 on both sides and the lower connecting plates 9 on both sides, along with two fastening bolts 12 and two nuts 13. This allows for convenient disassembly, replacement, and cleaning of the filter screen 16 in the liquid storage tank 1, effectively intercepting impurities in the liquid refrigerant and improving equipment reliability and service life.

[0043] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from the technical solution of this utility model shall still fall within the protection scope of this utility model.
