Description

Technical Field

[0001] This invention relates to the field of air conditioning technology, and more specifically, to an air guiding structure and an air conditioner. Background Technology

[0002] In the air conditioning industry, with increasing user demands for comfort and intelligence, the development and application of inverter technology have become more widespread. However, frequency changes lead to significant temperature variations inside the control box, especially at high frequencies. This causes significant heat generation in the components within the control box, resulting in decreased product reliability, increased maintenance rates, and a substantial reduction in market competitiveness over prolonged operation. Existing technologies utilize the pressure differences caused by varying air temperatures in different areas—that is, cold air flowing towards warm air—to create natural convection. However, without active air pressure for effective heat dissipation, the control box suffers from insufficient heat dissipation. Alternatively, dedicated fans are added to the air duct system to actively generate air pressure and improve cooling. However, this approach introduces additional materials and requires matching appropriate logic control, leading to design complexity and increased costs. Furthermore, existing technologies only briefly block water entering the air conditioner, leaving the water thrown into the control box outlet without further treatment. This can easily lead to long-term water accumulation and corrosion inside the air conditioner. Summary of the Invention

[0003] The present invention aims to solve at least one of the technical problems existing in the prior art or related art.

[0004] In view of this, one object of the present invention is to provide an air guiding structure.

[0005] Another object of the present invention is to provide an air conditioner.

[0006] To achieve the above objectives, the first aspect of the present invention provides an air guiding structure, comprising: an electrical control box assembly, including: an electrical control box body; and a top plate and a bottom plate disposed opposite to each other on both sides of the electrical control box body, wherein the top plate is provided with a first air outlet group and the bottom plate includes a second air outlet group; a fan assembly, including a fan and a partition, the partition including a third air outlet group; the electrical control box assembly and the fan assembly are respectively located on both sides of the partition; and an air guiding assembly, fixedly connected to the partition, the air guiding assembly including an air inlet communicating with the first air outlet group and an air outlet communicating with the third air outlet group.

[0007] Specifically, because hot air rises, the top plate is positioned higher than the bottom plate, thus placing the first air vent assembly at the top of the electrical control box, which is more conducive to the exhaust of hot air.

[0008] In this technical solution, by setting a fan and a partition in the fan assembly, setting a third air outlet group on the partition, and placing the electrical control box assembly and the fan assembly on opposite sides of the partition, the area where the fan and the electrical control box are located is divided into two smaller areas. When the fan rotates, it can generate a greater negative pressure and attract air from other areas more significantly. This negative pressure is transmitted through the third air vent group on the partition to the air outlet of the air guide component connected to the third air vent group, and then through the air inlet connected to the first air vent group of the electrical control box assembly to the main body of the electrical control box. As a result, the hot air inside the electrical control box is attracted by this negative pressure, flowing from the first air vent group into the air inlet of the air guide component, and then through the air outlet and the third air vent group into the fan side of the partition. Finally, it is discharged outside the air conditioner by the fan. Due to the loss of hot air, a negative pressure is also formed inside the electrical control box. The air with a lower external temperature is attracted by the negative pressure inside the electrical control box and enters the electrical control box through the second air vent group to cool the components inside the electrical control box. Through this cycle, the electrical control box is continuously cooled. The fan, originally used to cool the heat exchanger, utilizes the negative pressure it generates in this technical solution. Therefore, no new components are added to the inner wall of the electrical control box, and only a wind guide component is added to the air conditioner structurally. The volume and internal structure of the air conditioner itself remain basically unchanged, and the control system remains unchanged. This reduces the heat dissipation cost of the electrical control box, improves the heat dissipation effect, and enhances the reliability of the electrical control box, thereby improving the overall reliability of the unit and reducing the design and manufacturing difficulty.

[0009] In the above technical solution, preferably, the air guiding assembly includes: a cover plate, which is parallel to the top plate; an air guiding channel, which is disposed between the cover plate and the top plate; and an air guiding plate that forms the air guiding channel with the cover plate.

[0010] In this technical solution, the air guide assembly includes a cover plate and an air guide plate, forming a complete air guide channel, thereby creating an air duct. This allows the hot air in the electrical control box to be smoothly guided to the fan side of the partition, and then discharged outside the air conditioner under the action of the fan. The cover plate is parallel to the top plate, making the air guide structure compact and compatible with the original shape of the whole unit, which is convenient for design. The air guide channel is located between the top plate and the cover plate, so that the air duct is inside the whole unit, reducing the possibility of water intrusion into the air duct.

[0011] In the above technical solution, preferably, the air guide plate further includes: a waterproof plate, which is disposed at the air outlet, and the inner wall of the waterproof plate is an inclined surface facing the third air outlet group.

[0012] In this technical solution, by installing a waterproof plate at the air outlet, when water enters the air conditioner through the fan inlet and is thrown to the air outlet by the third air outlet group on the partition when the fan is rotating at high speed, the water can be blocked by the waterproof plate, thereby reducing the possibility of water entering the electrical control box through the air duct; the inner wall of the waterproof plate is a slope facing the third air outlet, so that after the water is blocked, it can flow along the slope to the bottom of the slope without entering the air duct.

[0013] In the above technical solution, preferably, the third air outlet group includes: multiple third air outlets and multiple water return outlets, wherein the distance of any water return outlet from the bottom of the slope is less than the distance of any third air outlet from the bottom of the slope; wherein at least one water return outlet is located at the bottom of the slope.

[0014] In this technical solution, the third air outlet group includes multiple air outlets. The position and size of the third air outlets can be flexibly set on the partition according to the relative position of the electrical control box and the fan, thereby improving the ventilation capacity without reducing the structural strength of the partition. It also includes multiple water return outlets, and the position of the water return outlets is closer to the bottom of the slope than the air outlets. This allows water accumulated at the bottom of the slope to flow from the water return outlets to the fan side of the partition for treatment along with other accumulated water. Placing at least one water return outlet at the bottom of the slope allows water to drain out as quickly as possible and also reduces water accumulation at the bottom of the slope.

[0015] In the above technical solution, preferably, a first flange is provided around the air outlet, and the air outlet is sealed to the partition through the first flange. The area of ​​the air outlet is not less than the area of ​​the third air outlet group.

[0016] In this technical solution, by providing a first flange around the air outlet, it is easy to connect and fix the air outlet to the partition. The air outlet is sealed to the partition through the first flange, which can reduce the loss during negative pressure transmission and improve the air guiding and heat dissipation capacity of the air guiding structure, thereby improving the reliability of the electrical control box. The area of ​​the air outlet is not less than the area of ​​the third air outlet group, so that the negative pressure generated by the fan can be completely transmitted to the air guiding channel, which also reduces negative pressure loss and improves the air guiding and heat dissipation capacity of the air guiding structure.

[0017] In the above technical solution, preferably, the air guide plate further includes: an air inlet plate, parallel to the cover plate, the air inlet plate being tightly fitted to the top plate; and an air inlet penetrating the air inlet plate, the air inlet being correspondingly arranged and sealed to the first air outlet group.

[0018] In this technical solution, the air inlet plate and the cover plate are parallel, which makes the structure compact and the air guiding structure conforms to the original shape of the whole machine, making it easy to design. On the other hand, it can make the air inlet plate fit tightly with the top plate, which further facilitates the sealing of the air inlet of the air inlet plate and the first air outlet group, thereby reducing the negative pressure loss in the air guiding groove, improving the air guiding capacity of the air guiding structure, and thus improving the heat dissipation capacity and reliability of the electrical control box.

[0019] In the above technical solution, preferably, the two ends of the cover plate are detachably connected to the top plate and the partition plate, respectively.

[0020] Sealing gaskets are provided at both ends of the cover plate where it connects to the top plate and the partition plate.

[0021] In this technical solution, the cover plate is detachably connected to the top plate and partition plate at both ends, which facilitates the fault repair and maintenance of the whole machine and its components.

[0022] The second aspect of the present invention provides an air conditioner including the air guide structure of any of the above-mentioned technical solutions. This can improve the heat dissipation and waterproofing capabilities of the electrical control box in the air conditioner, enhance the reliability of the electrical control box, extend its service life, thereby improving the reliability and extending the service life of the air conditioner, and reducing the design difficulty and manufacturing cost of the air conditioner.

[0023] In this technical solution, by adopting the air guide structure of any of the above technical solutions, the heat dissipation and waterproofing capabilities of the electrical control box in the air conditioner can be improved, the reliability of the electrical control box can be improved, and the service life of the electrical control box can be extended, thereby improving the reliability and extending the service life of the air conditioner, and reducing the design difficulty and manufacturing cost of the air conditioner.

[0024] In the above technical solution, preferably, the air conditioner includes: an air conditioner base plate, which is perpendicularly arranged to the partition of the air guide structure; a water receiving tray, which is located on one side of the fan assembly of the partition, and the distance from any return water inlet of the air guide structure to the air conditioner base plate is greater than the distance from the water receiving tray to the air conditioner base plate.

[0025] In this technical solution, by setting an air conditioning base plate perpendicular to the baffle in the air guiding structure, a receiving cavity is formed on the fan side of the baffle to facilitate the housing of the fan and other components; by setting a water receiving tray on the fan side of the baffle, and the position of the water receiving tray is closer to the air conditioning base plate than the position of the return water outlet, the water flowing back from the return water outlet can flow into the water receiving tray for unified drainage treatment and reduce the possibility of corrosion of the entire chassis.

[0026] In the above technical solution, preferably, the distance between the air outlet of the air guide structure and the air conditioner base plate is not greater than the distance between the air inlet and the air conditioner base plate.

[0027] In this technical solution, by setting the distance between the air outlet and the air conditioner base plate to be no greater than the distance between the air inlet and the air conditioner base plate, that is, the position of the air outlet is no higher than the position of the air inlet, when the waterproof plate fails and fails to block water from entering the air guide channel, the water cannot flow from the air outlet to the air inlet because the air inlet is higher, which reduces the possibility of water entering the electrical control box and improves the reliability of the whole machine.

Detailed Implementation

[0036] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0037] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and therefore the scope of protection of the invention is not limited to the specific embodiments disclosed below.

[0038] The following reference Figures 1 to 5 Some embodiments of the present invention are described.

[0039] like Figures 1 to 3As shown, an embodiment of the present invention provides an air guiding structure, including: an electrical control box assembly 20, including: an electrical control box body 200; and a top plate 202 and a bottom plate 204 disposed opposite to each other on both sides of the electrical control box body 200, wherein the top plate 202 is provided with a first air outlet group 206, and the bottom plate 204 includes a second air outlet group 208; a fan 300 assembly 30, including a fan 300 and a partition 302, the partition 302 including a third air outlet group 304; the electrical control box assembly 20 and the fan 300 assembly 30 are respectively located on both sides of the partition 302; and an air guiding assembly 10, fixedly connected to the partition 302, the air guiding assembly 10 including an air inlet 100 communicating with the first air outlet group 206 and an air outlet 102 communicating with the third air outlet group 304.

[0040] Specifically, because hot air moves upward, the top plate 202 is positioned higher than the bottom plate 204, thus placing the first air vent group 206 at the top of the electrical control box, which is more conducive to the exhaust of hot air.

[0041] In this embodiment, by providing a fan 300 and a partition 302 in the fan 300 assembly 30, and providing a third air outlet group 304 on the partition 302, and with the electrical control box assembly 20 and the fan 300 assembly 30 respectively located on both sides of the partition 302, the area where the fan 300 and the electrical control box are located is divided into two smaller areas. When the fan 300 rotates, it can generate a greater negative pressure, and the attraction of air to other areas is more significant. This negative pressure is transmitted through the third air vent group 304 on the partition 302 to the air outlet 102 of the air guide assembly 10 connected to the third air vent group 304, and then through the air inlet 100 connected to the first air vent group 206 of the electrical control box assembly 20 to the electrical control box body 200. As a result, the hot air in the electrical control box is attracted by this negative pressure and flows from the first air vent group 206 into the air inlet 100 of the air guide assembly 10. It then enters the fan 300 side of the partition 302 through the air outlet 102 and the third air vent group 304, and is finally discharged outside the air conditioner 40 by the fan 300. Due to the loss of hot air, a negative pressure is also formed inside the electrical control box. The air with a lower external temperature is attracted by the negative pressure inside the electrical control box and enters the electrical control box through the second air vent group 208 to cool the components inside the electrical control box. Through this cycle, the electrical control box is continuously cooled. In this embodiment, the fan 300, originally used to cool the heat exchanger, utilizes the negative pressure it generates. Therefore, no new components are added to the inner wall of the electrical control box, and only a wind guide assembly 10 is added to the air conditioner 40 structurally. The volume and internal structure of the air conditioner 40 remain basically unchanged, and the control system remains unchanged. This reduces the heat dissipation cost of the electrical control box, improves the heat dissipation effect, and enhances the reliability of the electrical control box, thereby improving the overall reliability of the unit and reducing the design and manufacturing difficulty.

[0042] like Figure 1As shown, in the above embodiment, preferably, the air guide assembly 10 includes: a cover plate 104, which is parallel to the top plate 202; an air guide groove 106, which is disposed between the cover plate 104 and the top plate 202; and an air guide plate 108 that forms the air guide groove 106 with the cover plate 104.

[0043] In this embodiment, the air guide assembly 10 includes a cover plate 104 and an air guide plate 108, forming a complete air guide groove 106, thereby forming an air duct. This allows the hot air in the electrical control box to be smoothly guided to the fan 300 side of the partition 302 and discharged outside the air conditioner under the action of the fan 300. The cover plate 104 is parallel to the top plate 202, making the air guide structure compact and compatible with the original shape of the whole machine, which is convenient for design. The air guide groove 106 is located between the top plate 202 and the cover plate 104, so that the air duct is inside the whole machine, reducing the possibility of water intrusion into the air duct.

[0044] like Figure 1 As shown, in the above embodiment, preferably, the air guide plate 108 further includes: a waterproof plate 110, which is disposed at the air outlet 102, and the inner wall of the waterproof plate 110 is an inclined surface facing the third air outlet group 304.

[0045] In this embodiment, by providing a waterproof plate 110 at the air outlet 102, when water enters the air conditioner 40 through the fan 300 and is thrown to the air outlet 102 by the third air vent group 304 on the partition 302 when the fan 300 is rotating at high speed, the water can be blocked by the waterproof plate 110, thereby reducing the possibility of water entering the electrical control box through the air duct; the inner wall of the waterproof plate 110 is a slope facing the third air vent 306, so that after the water is blocked, it can flow along the slope to the bottom of the slope without entering the air duct.

[0046] like Figure 3 As shown, in the above embodiment, preferably, the third air outlet group 304 includes: a plurality of third air outlets 306 and a plurality of return water outlets 308, wherein the distance of any return water outlet 308 from the bottom of the slope is less than the distance of any third air outlet 306 from the bottom of the slope; wherein at least one return water outlet 308 is located at the bottom of the slope.

[0047] In this embodiment, the third air vent group 304 includes multiple air vents. The position and size of the third air vent 306 can be flexibly set on the partition 302 according to the relative position of the electrical control box and the fan 300, and the ventilation capacity can be improved without reducing the structural strength of the partition 302. It also includes multiple water return ports 308, and the position of the water return ports 308 is closer to the bottom of the slope than the position of the air vents. This allows water accumulated at the bottom of the slope to flow from the water return ports 308 to the fan 300 side of the partition 302 for treatment along with other accumulated water. Setting at least one water return port 308 at the bottom of the slope allows water to drain out as quickly as possible and also reduces water accumulation at the bottom of the slope.

[0048] like Figure 1 and Figure 4 As shown, in the above embodiment, preferably, the air outlet 102 is provided with a first flange 112 around its perimeter, and the air outlet 102 is sealed to the partition 302 through the first flange 112. The area of ​​the air outlet 102 is not less than the area of ​​the third air outlet group 304.

[0049] In this embodiment, by providing a first flange 112 around the air outlet 102, it is convenient to connect and fix the air outlet 102 to the partition 302. Furthermore, the air outlet 102 is sealed to the partition 302 through the first flange 112, which can reduce the loss during negative pressure transmission, improve the air guiding and heat dissipation capacity of the air guiding structure, and thus improve the reliability of the electrical control box. The area of ​​the air outlet 102 is not less than the area of ​​the third air outlet group 304, so that the negative pressure generated by the fan 300 can be completely transmitted to the air guiding groove 106, which also reduces negative pressure loss and improves the air guiding and heat dissipation capacity of the air guiding structure.

[0050] like Figure 1 As shown, in the above embodiment, preferably, the air guide plate 108 further includes: an air inlet plate 114, parallel to the cover plate 104, the air inlet plate 114 being tightly fitted with the top plate 202; and an air inlet 100 penetrating the air inlet plate 114, the air inlet 100 being correspondingly provided with and sealed to the first air outlet group 206.

[0051] In this embodiment, the air inlet plate 114 is parallel to the cover plate 104. On the one hand, this makes the structure compact and the air guiding structure is compatible with the original shape of the whole machine, which is convenient for design. On the other hand, it allows the air inlet plate 114 to fit tightly with the top plate 202, which further facilitates the sealing between the air inlet 100 of the air inlet plate 114 and the first air outlet group 206, thereby reducing the negative pressure loss in the air guiding groove 106, improving the air guiding capacity of the air guiding structure, and thus improving the heat dissipation capacity and reliability of the electrical control box.

[0052] In the above embodiments, preferably, the two ends of the cover plate 104 are detachably connected to the top plate 202 and the partition plate 302, respectively.

[0053] Among them, sealing gaskets are provided at both ends of the cover plate 104 where it connects with the top plate 202 and the partition plate 302.

[0054] In this embodiment, the cover plate 104 is detachably connected to the top plate 202 and the partition plate 302 at both ends, which facilitates the fault repair and maintenance of the whole machine and its components.

[0055] like Figure 4As shown, another embodiment of the present invention provides an air conditioner 40, including the air guide structure of any of the above embodiments. This can improve the heat dissipation and waterproofing capabilities of the electrical control box in the air conditioner 40, improve the reliability of the electrical control box, and extend the service life of the electrical control box, thereby improving the reliability and extending the service life of the air conditioner 40, and reducing the design difficulty and manufacturing cost of the air conditioner 40.

[0056] In this embodiment, by adopting the air guide structure of any of the above embodiments, the heat dissipation and waterproofing capabilities of the electrical control box in the air conditioner 40 can be improved, the reliability of the electrical control box can be improved, and the service life of the electrical control box can be extended, thereby improving the reliability of the air conditioner 40 and extending the service life of the air conditioner 40, and reducing the design difficulty and manufacturing cost of the air conditioner 40.

[0057] In the above embodiment, preferably, the air conditioner 40 includes: an air conditioner base plate 402, which is perpendicularly arranged to the partition 302 of the air guide structure; a water receiving tray 404, which is located on one side of the fan 300 assembly 30 of the partition 302, and the distance between any return water port 308 of the air guide structure and the air conditioner base plate 402 is greater than the distance between the water receiving tray 404 and the air conditioner base plate 402.

[0058] In this embodiment, by setting an air conditioning base plate 402 perpendicular to the partition 302 in the air guiding structure, a receiving cavity is formed on the fan 300 side of the partition 302 to facilitate the housing of the fan 300 and other components; by setting a water receiving tray 404 on the fan 300 side of the partition 302, and the position of the water receiving tray 404 is closer to the air conditioning base plate 402 than the position of the return water inlet 308, the water returning from the return water inlet 308 can flow into the water receiving tray 404 for unified drainage treatment and reduce the possibility of corrosion of the entire chassis.

[0059] In the above embodiments, preferably, the distance between the air outlet 102 of the air guide structure and the air conditioner base plate 402 is not greater than the distance between the air inlet 100 and the air conditioner base plate 402.

[0060] In this embodiment, by setting the distance between the air outlet 102 and the air conditioner base plate 402 to be no greater than the distance between the air inlet 100 and the air conditioner base plate 402, that is, the position of the air outlet 102 is no higher than the position of the air inlet 100, when the waterproof plate 110 fails and fails to block water from entering the air guide duct 106, the water cannot flow from the air outlet 102 to the air inlet 100 because the position of the air inlet 100 is higher, which reduces the possibility of water entering the electrical control box and improves the reliability of the whole machine. Specific Implementation Example 1:

[0062] like Figures 1 to 3As shown, in a specific embodiment of the present invention, the air guiding structure includes an electrical control box body 200, and a top plate 202 and a bottom plate 204 vertically disposed opposite each other on both sides of the electrical control box body 200. The top plate 202 has a first air vent group 206, and the bottom plate 204 has a second air vent group 208. A fan 300 assembly 30 includes a fan 300 and a partition 302, the partition 302 including a third air vent group 304. The electrical control box assembly 20 and the fan 300 assembly 30 are respectively located on both sides of the partition 302. An air guiding assembly 10 is fixedly connected to the partition 302, and the air guiding assembly 10 includes an air inlet 100 that is sealed and communicates with the first air vent group 206, and an air outlet 102 that is sealed and communicates with the third air vent group 304. The air guide assembly 10 includes a cover plate 104 and an air guide plate 108 parallel to the top plate 202. The cover plate 104 and the air guide plate 108 are sealed together to form an air guide groove 106; Figure 2 As shown, the air guide plate 108 includes an air inlet plate 114 and a waterproof plate 110. The air inlet plate 114 is tightly fitted and sealed to the top of the electrical control box. The air inlet 100 is on the air inlet plate 114. The waterproof plate 110 is bent downwards at a certain angle, so that the inner wall of the waterproof plate 110 is an inclined surface facing the partition 302. This inclined surface is located inside the air outlet 102. Figure 3 As shown, the third air vent group 304 includes multiple third air vents 306 and multiple return water inlets 308. The position of any return water inlet 308 is lower than the position of any third air vent 306, and at least one return water inlet 308 is at the bottom of the slope. The area of ​​the air outlet 102 is larger than the area of ​​the third air vent group 304. The air outlet 102 has a first flange 112 around its perimeter, which is fixedly connected to and sealed with the partition plate 302. In addition, the two ends of the cover plate 104 are detachably connected to the top plate 202 and the partition plate 302, respectively.

[0063] When the main body 200 of the electrical control box is working, the electrical components inside the box continuously generate heat, causing the air temperature inside the box to rise. The hot air naturally rises and accumulates at the top plate 202. The fan 300 generates negative pressure on one side of the partition 302. Due to the excellent sealing of the air ducts throughout the entire air guiding structure, the negative pressure is sequentially transmitted through the third air outlet group 304 on the partition 302, the air outlet 102 and air inlet 100 of the air guiding assembly 10, and the first air outlet group 206 of the electrical control box, attracting the hot air accumulated at the top plate 202. Hot air flows out from the first air outlet group 206, passes through the air inlet 100 and air outlet 102 of the air guide assembly 10 and the third air outlet group 304 of the partition 302, and is discharged to the fan 300 side of the partition 302, and then discharged outside the whole machine by the fan 300; after the hot air flows out from the electrical control box, a negative pressure is also formed inside the electrical control box. Under the attraction of this negative pressure, the relatively cool air from the outside enters the electrical control box from the second air outlet group 208 of the base plate 204, and exchanges heat with the electrical components inside the electrical control box, thereby achieving continuous heat exchange and cooling inside the electrical control box.

[0064] If water enters the air guide duct 106 through the third air outlet group 304 on the partition 302, it will be blocked by the waterproof plate 110 of the air outlet 102 and flow from the slope to the bottom of the slope, and then flow back to the fan 300 side of the partition 302 through the return water port 308. Specific Implementation Example 2:

[0066] like Figures 3 to 5 As shown, another specific embodiment of the air conditioner 40 of the present invention includes the air guide structure of the first specific embodiment.

[0067] The air conditioner 40 in this specific embodiment also includes an air conditioner base plate 402 perpendicular to the partition 302 in the air guide structure, and a water receiving tray 404 is provided on the air conditioner base plate 402. The position of the water receiving tray 404 is lower than the position of the return water inlet 308, so that the water returning from the return water inlet 308 can flow into the water receiving tray 404 and finally be discharged uniformly. In addition, the air outlet 102 in the air guide structure is lower than the air inlet 100, which can reduce the possibility of water flowing from the air outlet 102 to the air inlet 100 and entering the electrical control box, thereby improving the reliability of the whole machine.

[0068] The technical solution of the present invention has been described in detail above with reference to the accompanying drawings. Through the technical solution of the present invention, heat dissipation circulation of the electrical control box is achieved simply by improving the structure, thereby reducing costs, simplifying the design, improving the reliability of the electrical components of the electrical control box, and extending the service life of the electrical components of the electrical control box, thereby reducing the overall cost of the air conditioner and improving the overall reliability of the unit.
