[0001] This invention relates to the field of air conditioning technology, specifically to a dual-source air-wall air conditioner. Background Technology

[0002] To improve the security of data center cooling systems, dual-source precision air conditioners are increasingly being chosen by users. However, with the rapid increase in the heat output of electronic components, the drawback of ordinary dual-source precision air conditioners having a relatively small cooling range under the same framework is becoming increasingly apparent. In traditional cooling equipment, the fan is usually placed at the top, with dual-source coils below and the compressor at the bottom. This structure limits the size of the coils and significantly reduces the air delivery area of ​​the fan, resulting in a limited overall cooling capacity, reduced space utilization, and an inability to adapt to the increasing heat output of electronic components.

The output of the air-cooled condenser 4 is connected to the dual-source coil 2. An electric valve 6 is located at the output of the dual-source coil 2. This dual-source air-wall air conditioner addresses existing problems by... The internal structure has been adjusted, placing the fan on the side, followed by the coil, and finally the compressor. Side air delivery increases the air delivery area, and the coil size and airflow area are also larger, resulting in a greater cooling capacity. This better meets the needs of high-density, high-power applications. All components of the original system remain unchanged; only the structure has been adjusted for ease of implementation. The optimized frame structure of the dual-source air conditioner provides more cooling capacity while ensuring the safety of the refrigeration system. It is also better suited to the increasing heat generation power of electronic components. The optimized structural space of the dual-source air conditioner reduces the footprint required for the same cooling needs, saving costs.

[0033] To control the flow of refrigerant in the air conditioner, an installation pipe 7 is provided in the electric valve 6. The installation pipe 7 houses a control component 8 for limiting the flow. A cleaning component 9 is located on the top of the control component 8. Connecting pipes 701 are fixedly connected to both ends of the installation pipe 7, and a retaining ring 702 is fixedly connected to the bottom of the installation pipe 7. The inner wall of the retaining ring 702 has an internal threaded groove 703. The control component 8 includes a mounting base 801, which is placed inside and slidably connected to the installation pipe 7. A retaining base 802 is fixedly connected to the bottom of the mounting base 801, and the outer ring wall of the retaining base 802 is connected to the retaining ring 702. 2. The inner wall is slidably connected. The fixed seat 802 has an annular groove 803 around its perimeter that matches the internal thread groove 703.

One end of the guide plate 809, away from the mounting base 801, is fixedly connected to the inner wall of the mounting tube 7. The guide plate 809 is placed in the mounting groove 805 and slidably connected to the groove wall. The mounting base 801 has through-holes 810 on both sides near the connecting tube 701. The diameter of the through-holes 810 is larger than the inner diameter of the connecting tube 701. The axes of the through-holes 810 and the connecting tube 701 coincide. A filter rod 811 is installed inside the through-hole 810 and slidably connected to the wall of the through-hole 810. The diameter of the filter rod 811 is larger than the inner diameter of the connecting tube 701. The mounting base 801 is placed inside the mounting tube 7. The connecting hole 810 on the side wall of the mounting base 801 coincides with the position of the connecting tube 701 of the electric valve 6. A filter rod 811 for filtering impurities is built into the connecting hole 810 to prevent impurities from flowing in the air conditioning pipe. The return spring 807 drives the mounting base 801 to move closer to the mounting tube 7 and tighten it. The sealing strip 804 on the bottom surface of the mounting base 801 enters the groove of the fixing ring 702 to seal the entire device and prevent valve body leakage. The air conditioning refrigerant flows through the filter rod 811, which can be replaced and is convenient.

[0034] To facilitate timely cleaning of the air conditioning ducts, a servo motor 901 is included in the cleaning component 9. A positioning ring 902 is fitted onto the surface of the servo motor 901, and the bottom of the positioning ring 902 is fixedly connected to the mounting base 801. A pulley 903 is fixedly connected to the output end of the servo motor 901, and a connecting belt 904 is fitted onto the surface of the pulley 903. The top of the mounting base 801 has a hole for the connecting belt 904 to pass through, and the side wall of the mounting base 801 has a through mounting hole 906. The mounting hole 906 is located at the top of the connecting hole 810, and a fixing tube 905 is installed inside the mounting hole 906. The end of the connecting belt 904 away from the pulley 903 is fitted onto the surface of the fixing tube 905. The inner cavity of the fixing tube 905 is divided into a fixing chamber 907 and a limiting chamber. Chamber 908, a limiting chamber 908, is distributed on both sides of and communicates with fixed chamber 907. The inner diameter of limiting chamber 908 is larger than that of fixed chamber 907. Fixed chamber 907 contains a telescopic spring 909. Limiting chamber 908 contains a limiting plate 910. The two limiting plates 910 are symmetrically distributed along the axis of fixed tube 905. Both ends of the telescopic spring 909 are in contact with the limiting plate 910. A connecting rod 911 is fixedly connected to the side of the two limiting plates 910 that is away from each other. The end of the connecting rod 911 away from the limiting plate 910 extends through fixed tube 905 into mounting hole 906. The connecting rod 911 is slidably connected to fixed tube 905. A cleaning gripper 912 is fixedly connected to the end of the connecting rod 911 away from fixed tube 905. 12 is made of flexible rubber. The cleaning gripper 912 has an inclined surface 913 on the side near the inner wall of the mounting hole 906. The end of the cleaning gripper 912 away from the connecting rod 911 contacts the inner wall of the limiting ring 704. In daily use, under the restriction of the limiting ring 704 at the top of the mounting tube 7, the cleaning gripper 912 is placed inside the mounting hole 906. When cleaning the electric valve 6 is required, the mounting seat 801 can be pressed, causing it to move downwards inside the mounting tube 7. During this downward movement, the cleaning grippers 912 at both ends inside the mounting hole 906 will also move synchronously, aligning the axis of the mounting hole 906 with the connecting tube 701. At this moment, driven by the elastic force of the telescopic spring 909, the cleaning grippers 912 at both ends will extend out of the mounting hole 906 and enter... Inside the connecting pipe 701, impurities accumulate due to blockage by the filter rod 811. At this moment, the servo motor 901 is activated, driving the fixed pipe 905 and the cleaning grippers 912 at both ends to rotate inside the connecting pipe 701. The cleaning grippers 912 are made of flexible rubber and can make close contact with the inner wall of the connecting pipe 701. Under the impact of part of the refrigerant flow, impurities will also enter the mounting hole 906 and stay in front of the fixed pipe 905, completing the cleaning. The mounting base 801 is released, and driven by the surrounding return springs 807, the mounting base 801 moves upward, and its connecting hole 810 will coincide with the axis of the connecting pipe 701 again. During this period, the filter rod 811 can be replaced. The entire device can filter the flow to a certain extent and is easy to clean the filtered impurities.

[0035] Working principle

[0036] To ensure the safety of the refrigeration system and adapt to the increasing heat output of electronic devices, dual-cold-source technology and a wall-mounted air conditioner are combined to form a dual-cold-source wall-mounted air conditioner. Compared with ordinary precision air conditioners, this invention applies dual-cold-source technology, further ensuring the safety of the refrigeration system. It also leverages the spatial structural advantages of wall-mounted air conditioners; within the same structural framework, the coil size of the wall-mounted air conditioner can be made larger, achieving twice the cooling capacity of ordinary precision air conditioners. The fan is located on the side, delivering air into the air conditioning system through side airflow. The advantage of this method is a larger airflow area, enabling more effective airflow throughout the space. The dual-source cooling coil 2 is located behind the fan, and its larger size and airflow area allow it to receive more airflow, thereby increasing the cooling capacity. By adjusting the internal structure, the positions of the fan, coil, and compressor 3 are made more reasonable, improving the efficiency of the air conditioner. Because the structural space of the device is reduced, it can save floor space and thus save costs under the same cooling demand. It also adapts to the trend of increasing heat generation power of electronic devices: As the power of electronic devices increases, the demand for air conditioning also increases. By optimizing the structure of the dual-source air conditioner, it can better adapt to this trend and provide sufficient cooling effect.

[0037] The electric valve 6 controls the flow of refrigerant. Its return spring 807 drives the mounting base 801 to approach and tighten towards the mounting pipe 7. The sealing strip 804 on the surface of the bottom mounting base 801 enters the groove of the fixing ring 702 to seal the entire device and prevent valve leakage. The air conditioning refrigerant flows through the filter rod 811, which is easy to replace. In daily use, under the restriction of the top limit ring 704 of the mounting pipe 7, the cleaning handle 912 is placed in the mounting hole 906. When it is necessary to clean the electric valve 6, the mounting base 801 can be pressed, causing the mounting base 801 to move down in the mounting pipe 7. During the downward movement, the cleaning handles 912 at both ends in the mounting hole 906 will also move synchronously, so that the axis of the mounting hole 906 coincides with the connecting pipe 701. At this time, driven by the elastic force of the extension spring 909, the cleaning handles 912 at both ends will extend out of the mounting hole 906 and enter the mounting pipe 701. The refrigerant is introduced into the connecting pipe 701. Due to the blockage of the filter rod 811, impurities accumulate in the connecting pipe 701. At this moment, the servo motor 901 is activated, driving the fixed pipe 905 and the cleaning grippers 912 at both ends to rotate inside the connecting pipe 701. The cleaning grippers 912 are made of flexible rubber and can make close contact with the inner wall of the connecting pipe 701. Under the impact of part of the refrigerant flow, the impurities will also enter the mounting hole 906 and stay in front of the fixed pipe 905, completing the cleaning. The mounting base 801 is released, and under the drive of the surrounding return springs 807, the mounting base 801 moves upward, and its connecting hole 810 will coincide with the axis of the connecting pipe 701 again. During this process, the filter rod 811 can be replaced. The whole device can filter the flow to a certain extent and is easy to clean the filtered impurities. It filters the flow to a certain extent to ensure the smooth and stable operation of the air conditioning system. There is no need to disassemble and replace the electric valve 6, making it very convenient to use.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
