Description

Technical Field

[0001] This utility model belongs to the field of observation windows, specifically an observation window for an argon-filled air conditioning unit. Background Technology

[0002] Air conditioning unit observation windows are usually installed on the outside of air conditioning equipment to facilitate monitoring of the internal operating status of the air conditioning system or maintenance inspection. Through the observation window made of transparent material, staff can easily see the airflow, filter, fan, evaporator and other components inside the air conditioning unit.

[0003] The observation window of an air conditioning unit is usually filled with nitrogen gas, which effectively reduces the moisture difference between the inside and outside of the window and prevents fogging of the glass surface caused by excessive temperature difference. However, because nitrogen gas has low transparency, it has a certain impact on the observation effect, which can easily affect the accuracy of the judgment of the air conditioning unit's working status.

[0004] In summary, this utility model provides an observation window for an argon-filled air conditioning unit to solve the above problems. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0006] An observation window for an argon-filled air conditioning unit includes an outer frame, two outer frames, an inner cavity of the outer frame containing plexiglass, and a cavity between the two outer frames;

[0007] The two outer frames are integrally welded together, and the interior is filled with argon gas for heat insulation and to prevent condensation.

[0008] Furthermore, in this utility model, reinforcing strips are fixedly connected to the sides of the two outer frames that are close to each other, and bolt holes are provided on the back of the rear outer frame.

[0009] Furthermore, in this utility model, the inner cavity of the bolt hole is provided with a bolt, and the two reinforcing strips are connected by bolt threads.

[0010] Furthermore, in this invention, air holes are provided on both sides of the cavity, and the air holes are sealed by rubber plugs.

[0011] Beneficial effects: This utility model has the following beneficial effects:

[0012] This invention uses an outer frame, plexiglass, and a cavity to form the main body of the observation window. Because the cavity is filled with argon gas, which has a low refractive index and better transparency, the observation window filled with argon gas provides a clearer visual effect compared to nitrogen gas, thus better ensuring the accuracy of the judgment results. Furthermore, argon gas has a lower thermal conductivity than nitrogen gas, resulting in slightly better heat insulation performance, further reducing heat exchange, improving energy efficiency, and ensuring heat insulation and condensation prevention. Although nitrogen gas already has good corrosion resistance, argon gas, due to its higher inertness, provides stronger corrosion protection, making it suitable for environments with high corrosion resistance requirements.

[0018] To better understand the technical content of this utility model, specific embodiments are described below in conjunction with the accompanying drawings. Various aspects of this utility model are described in this disclosure with reference to the accompanying drawings, which illustrate numerous illustrative embodiments. The embodiments of this disclosure are not necessarily defined to include all aspects of this utility model. It should be understood that the various concepts and embodiments described above, as well as those described in more detail below, can be implemented in any of many ways, because the concepts and embodiments disclosed in this utility model are not limited to any particular implementation. Furthermore, some aspects of this utility model can be used alone or in any suitable combination with other aspects disclosed in this utility model.

[0019] Example 1

[0020] like Figure 1-3 As shown, this is the first embodiment of the present invention. This embodiment provides an observation window for an argon-filled air conditioning unit, including an outer frame 1. There are two outer frames 1. The inner cavity of the outer frame 1 is provided with plexiglass 2, and a cavity 3 is provided between the two outer frames 1.

[0021] The two outer frames are welded together as a whole, and the interior is filled with argon gas for heat insulation and condensation prevention.

[0022] like Figure 1-3As shown, the outer frame 1, plexiglass 2, and cavity 3 constitute the main body of the observation window. Since the cavity 3 is filled with argon gas, which has a low refractive index and better transparency, the observation window filled with argon gas is clearer in terms of visual effect than that filled with nitrogen gas, thus better ensuring the accuracy of the judgment results. Furthermore, argon gas has a lower thermal conductivity than nitrogen gas, so it is slightly better in terms of heat insulation performance, which can further reduce heat exchange, improve energy saving effect, and ensure heat insulation and anti-condensation. Although nitrogen gas already has a good anti-corrosion effect, argon gas, due to its higher inertness, can provide stronger anti-corrosion protection and is suitable for some environments with high anti-corrosion requirements.

[0023] Example 2

[0024] Reference Figure 2 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0025] In this embodiment, reinforcing strips 4 are fixedly connected to the side of the two outer frames 1 that are close to each other, and bolt holes 5 are opened on the back of the rear outer frame 1.

[0026] Bolts are installed inside the bolt hole 5, and the two reinforcing bars 4 are connected by bolt threads.

[0027] Air holes are provided on both sides of cavity 3, and the air holes are sealed with rubber plugs.

[0028] like Figure 2 As shown, one of the two vents is for air intake and the other for air exhaust. During the argon filling process, the rubber stopper is first removed, and argon is filled into the cavity 3 through the vent on one side. During the filling process, the original air inside the cavity 3 is discharged through the vent on the other side until the argon concentration inside the cavity 3 reaches 100%. At this point, the rubber stopper can be used for sealing. At the same time, silicone sealant can be used to enhance the sealing performance between the vent and the rubber stopper. The bolt hole 5 is used to accommodate bolts. The bolts can be used to fix the front and rear reinforcing strips 4 to each other, thereby enhancing the stability of the overall structure.

[0029] In use, the outer frame 1, plexiglass 2, and cavity 3 are welded together and filled with argon gas. When filling with argon gas, first remove the rubber plugs in the two vent holes, and then fill the cavity 3 with argon gas through one of the vent holes. During the filling process, the original air inside the cavity 3 is discharged through the other vent hole until the argon gas concentration inside the cavity 3 reaches 100%. At this point, seal it with a rubber plug. While sealing, silicone sealant can be used to enhance the sealing performance between the vent hole and the rubber plug. Because argon gas has a lower refractive index, it has better transparency. Compared with nitrogen gas, the observation window filled with argon gas is clearer in terms of visual effect, which can better ensure the accuracy of the judgment results. In addition, argon gas has a lower thermal conductivity than nitrogen gas, so it is slightly better in terms of heat insulation performance, which can further reduce heat exchange and ensure heat insulation and anti-condensation. Although nitrogen gas already has a good anti-corrosion effect, argon gas can provide stronger anti-corrosion protection due to its higher inertness.
