Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of building drainage, in particular to a method for installing a concealed air conditioner condensate pipe. BACKGROUND

[0002] In the traditional structure and construction method, the air conditioner condensate vertical pipe is usually installed in an open manner or directly connected with the building drainage system. However, this method has problems such as easy aging of the pipe, affecting the appearance and overall effect of the building facade, and with the increasing construction level of modern residential projects and the increasing demand for living comfort, this method has failed to keep up with the mainstream. The concealed installation of the air conditioner outdoor unit and the condensate drainage system has become the mainstream way of building facade.

[0003] In recent years, in order to improve the appearance of buildings, the condensate vertical pipe is usually embedded in the concealed design of the side wall cavity of the bay window, and an enclosed space is formed by wrapping with masonry structure. Although this construction method solves the problems of easy aging and visual effect of exposed pipes, the internal environment of the cavity is complex, and water accumulation often occurs due to poor condensate drainage, which further causes the surrounding wall of the bay window cavity to be damp and moldy.

[0004] There are currently three ways to prevent water accumulation in the cavity:

[0005] (1) Gravity drainage: The current mainstream technology relies on the natural slope of the condensate vertical pipe for gravity drainage, and a drainage hole is usually provided at the bottom of the cavity to communicate with the external environment. However, in actual engineering, due to the narrow internal space of the cavity and insufficient installation precision of the pipe, the drainage slope is difficult to meet the specification requirement of ≥1%, and about 35% of similar projects are caused by local reverse slope due to construction errors, forming a water accumulation area.

[0006] (2) Passive moisture-proof treatment: By brushing waterproof paint or laying waterproof roll material on the inner wall of the cavity, it is attempted to block the penetration of water. However, in actual application, long-term water accumulation environment will still cause adhesion failure between the waterproof layer and the masonry, and the adhesion strength will decrease by about 62% after 72 hours of continuous soaking, and the moisture diffusion problem caused by water accumulation cannot be solved.

[0007] (3) Mechanical auxiliary drainage: A few high-end projects attempt to install a micro drainage pump at the bottom of the cavity, but the opening rate of the cavity access hole is insufficient, which causes difficulties in equipment maintenance, and has problems such as increased energy consumption and high cost, which is difficult to promote on a large scale.

[0008] The existing technology mainly has the following key problems:

[0009] The structural design has defects, the cavity space and the pipeline layout do not form a coordinated drainage system, the drainage hole is easy to be blocked by construction waste, and there is a lack of effective secondary drainage guarantee mechanism, resulting in insufficient drainage power; traditional masonry materials such as aerated concrete blocks have a water absorption rate of 8%-12%, which becomes a "water storage layer" in a humid environment, accelerates the growth of mold, and causes the moisture-proof material to fail; the pipeline installation lacks standardized positioning tooling, and manual construction cannot guarantee the slope accuracy, with a deviation of generally ±0.5%-0.8%, and the waterproof node processing inside the cavity is rough, resulting in a high risk of leakage; the closed cavity is difficult to maintain, only about less than 30% of the building scheme in existing housing construction has a detachable panel designed on the cavity, and a systematic humidity monitoring and early warning mechanism is not formed. The cavity is in a high-humidity environment (relative humidity > 85%) for a long time, and eventually causes mold growth around the window wall through capillary action.

[0010] In summary, it is found that the prior art at least has the following technical problems:

[0011] The existing air conditioner condensing pipe cavity installation structure and construction technology has the problems of insufficient drainage power, material moisture-proof failure, low construction accuracy, and difficulty in maintenance. SUMMARY

[0046] In one embodiment, in S1, when embedding the first water stop and the second water stop connected with the drainage vertical pipe, it is necessary to position by wire hanging, to ensure the coaxiality and perpendicularity of the first water stop and the second water stop, so that there is a gap between the outer wall of the installed drainage vertical pipe and the inner wall of the first water stop, to avoid the water guided by the drainage vertical pipe from contacting the inner wall of the first water stop and spreading to the lower apron.

[0047] The beneficial effects of the application are as follows:

[0048] The present application effectively solves the core problems of insufficient drainage power, material moisture failure, low construction precision and difficult maintenance in the traditional air conditioner condensing pipe concealed installation, and can effectively improve the construction efficiency while ensuring the construction quality, avoiding the problems of water accumulation in the bay window dark cavity and pipe structure leakage, and has the following advantages: (1) The drainage efficiency is significantly improved: through the double-path flow guide design, the gap between the outer wall of the drainage vertical pipe and the inner wall of the first water stop joint forms an external natural flow guide channel, combined with the internal main drainage path of the drainage vertical pipe, realizing "double-channel drainage". Even if the vertical pipe is blocked, the external gap can still guide the water, avoiding water accumulation in the bay window dark cavity, preventing the bay window wall from being moldy.

[0049] The gravity drainage is optimized by increasing the diameter of the first water stop joint, so that the diameter of the first water stop joint is two grades larger than the diameter of the drainage vertical pipe, ensuring sufficient flow guide gap, allowing water in the bay window dark cavity and water outside the water supply pipe to flow from top to bottom along the flow guide gap and the outer wall of the drainage vertical pipe to the lower air conditioner position, and evaporating the water or guiding the water to the outside of the building through the ground of the air conditioner position, and relying on the drainage vertical pipe to guide and drain the water outside the water supply pipe, directly solving the problem of water droplets formed by condensate water overcooling on the surface of the water supply pipe or water droplets generated by water supply pipe leakage in the bay window dark cavity, thereby avoiding the phenomenon of excessive humidity in the bay window dark cavity and the wall caused by water accumulation in the bay window dark cavity; at the same time, the natural gravity slope is combined to make the water in the bay window dark cavity flow out along the flow guide gap, without the need for additional drainage power to achieve efficient drainage, also solving the problem of insufficient drainage power of traditional concealed pipe drainage.

[0050] (2) The moisture-proof and sealing performance is enhanced: the first and second water stop joints are pre-buried with concrete pre-buried process, tightly bonded with the upper and lower floating plates to avoid joint cracks, and the pre-buried positioning is accurate, combined with the sealing connection process of glue connection of the drainage vertical pipe and the air conditioner condensate drainage pipe, effectively preventing the leakage of air conditioner condensate water and internal drainage of the drainage vertical pipe to the outside, avoiding the error of later installed pipes, reducing the service life of the pipes, and avoiding pipe leakage.

[0051] Compared with the traditional floating plate post-punching installation of water stop, the post-punching installation will cause cracks at the joint of the first and second water stops and the installation hole of the upper and lower floating plates. Even if the cracks are filled with sealant, the cracks will reappear due to the cyclic stress of thermal expansion and contraction, and even the cracks will expand, and water will easily seep into the floating plate through the cracks to form water storage. The pre-embedded water stop can make the water stop and the floating plate concrete integrated, and the joint is complete without cracks, avoiding water accumulation in the floating window cavity, water accumulation in the air conditioning site, and water flowing from the surface of the drainage vertical pipe into the floating plate concrete to form water storage, thereby increasing the humidity in the floating window cavity and affecting the mold of the wall of the floating window cavity.

[0052] By setting a movable joint at the drainage vertical pipe in the air conditioning site, the drainage vertical pipe is flexibly connected, and the movable joint has good sealing performance, is easy to install and disassemble, is convenient for maintenance of the drainage vertical pipe in the later period, and saves maintenance cost.

[0053] (3) Construction precision and efficiency are improved: standardized pre-embedded positioning: the water stop is pre-embedded before concrete pouring, the flange side is accurately aligned with the lower side of the floating plate, and the pipe height is ensured to be consistent through template positioning technology, such as "the pipe of the first water stop is flush with the upper side of the lower floating plate, and the pipes of the two second water stops are higher than the upper side of the upper floating plate", thereby significantly reducing the positioning error of manual hole opening and the installation height error of the water stop compared with non-pre-embedded post-punching, and the bonding strength of the pre-embedded water stop and the floating plate concrete is higher.

[0054] Modular installation: by using standardized interfaces for water three-way valves, movable joints and other components, only glue sealing connection is needed in sequence during construction, the operation process is simplified, the dependence on worker skills is reduced, the reliability of the connection is ensured, standardized construction is easier to achieve, the construction effect is better, and the proportion of pipe structure water leakage in the floating window cavity in the building is reduced.

[0055] (4) Breakthrough in maintenance convenience: multifunctional use of flow guiding gap: the gap between the drainage vertical pipe and the first water stop has flow guiding and maintenance functions. Since the size of the flow guiding gap is large, a flashlight or a camera can be inserted through the gap to observe the blockage and water accumulation in the floating window cavity, or an endoscope can be used to observe the situation in the floating window cavity. When repair action is needed, a drainpipe can be inserted to directly clean up, without damaging the back brick wall of the floating window cavity, so that quick repair can be performed.

[0056] Layered independent maintenance of floating window cavity: the drainage vertical pipes of the floating window cavities on each floor of the building are independently connected, and only the corresponding movable joint needs to be disassembled for maintenance when single-layer failure occurs, avoiding the drawbacks of traditional hidden pipes "pulling a hair and moving the whole body". The time for maintenance and repair can be reduced, the maintenance efficiency can be improved, and the maintenance cost can be reduced.

[0057] (5) Long-term cost reduction: reduce maintenance frequency: double-channel drainage structure can effectively reduce the probability of blockage of the drainage vertical pipe inside, the flow guide gap, combined with moisture-proof material and sealing process, can keep the humidity in the casement dark cavity not exceed the standard, so as to avoid the problem of moisture return and mildew of the casement dark cavity wall on the bedroom side, significantly prolong the service life of the wall surface and wall skin, reduce the long-term use decoration cost; And also significantly prolong the service life of the pipeline, reduce the maintenance cost in the later period.

[0058] Energy saving and environmental protection: the flow guide gap relies on natural gravity to drain water in the casement dark cavity, and the outer wall of the drainage vertical pipe relies on gravity to guide the condensation or seepage of the water pipe surface, without adding energy-consuming equipment such as water pump, which meets the requirements of green building.

[0075] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application.

[0076] The air conditioner condensing pipe hidden cavity installation construction method provided in the embodiments of the present application is constructed through the steps of pipe pre-burying and pipe installation, the drainage vertical pipe is connected to the second water stop after passing through the first water stop and being connected to the movable joint, the water in the bay window hidden cavity and the condensation water on the surface of the water supply pipe are guided to the air conditioner site for volatilization or external drainage by using the flow guiding gap and the outer wall of the drainage vertical pipe; the movable joint has good sealing performance and is easy to install and disassemble, which is convenient for later maintenance and saves maintenance cost; the drainage vertical pipe is connected to the water supply tee joint after being connected to the second water stop; the water supply pipe is connected to the water supply tee joint by passing through another second water stop, thereby forming an independent air conditioner condensate water drainage path; the three-channel drainage is formed by the flow guiding gap, the outer wall and the inner wall of the drainage vertical pipe, the pre-buried water stop sealing floating plate perforation, the maintenance design of the flow guiding gap and the modular installation of the pipe fittings, thereby realizing efficient drainage, moisture-proof and corrosion-proof of the air conditioner condensate water and the bay window hidden cavity, accurate and convenient maintenance of construction, and effectively solving the problems of insufficient drainage power, moisture-proof material failure, low construction precision and difficult maintenance of the existing air conditioner condensing pipe hidden cavity installation structure and construction technology.

[0077] The first embodiment of the air conditioner condensing pipe hidden cavity installation construction method is shown in Figures 1 to 4 As shown in the figure, it comprises S1, a pipe pre-burying construction step: S1.1, a first water stop, the first water stop is pre-buried in the lower floating plate during concrete pouring, and the flange side of the first water stop is located on the lower side of the lower floating plate, and the pipe opening of the first water stop is flush with the upper side of the lower floating plate;

[0078] S1.2, two second water stops, the second water stops are pre-buried in the upper floating plate during concrete pouring, and the flange side of the second water stop is located on the lower side of the upper floating plate; the pipe opening of the second water stop is higher than the upper side of the upper floating plate and is located in the air conditioner site, which is used to avoid the existence of low position or gap in the combination of the upper floating plate and the second water stop, so that the combination of the second water stop and the concrete of the upper floating plate remains complete, and the water at the air conditioner site is prevented from accumulating in the low position or gap to cause water storage in the concrete of the upper floating plate; the two second water stops are separated and arranged side by side;

[0079] S1.3, air conditioner reserved sleeve embedded construction steps: S1.31, through the plastic or reinforcement support before the wall concrete pouring, according to the construction drawing installation air conditioner reserved sleeve, and the two ends of the air conditioner reserved sleeve from high to low, along the lateral indoor wall surface of the bedroom to the air conditioner site wall surface of the outdoor inclined setting, require air conditioner reserved sleeve to tilt 5% outward;

[0080] S1.32, after the installation of air conditioner reserved sleeve, cover the two ends of the air conditioner reserved sleeve with end cap;

[0081] S1.33, install the wall formwork, cover the air conditioner reserved sleeve to the wall formwork, and then pour the concrete;

[0082] S1.34, after the completion of concrete pouring, remove the end cap of the air conditioner reserved sleeve;

[0083] S1.4, air conditioner site preset waterproof structure: S1.41, before concrete pouring, install the formwork of the water dropper on the formwork of the lower side of the lower floating plate according to the preset position of the drawing, so that the water dropper is arranged adjacent to the entrance of the air conditioner site;

[0084] S1.42, after the concrete pouring and forming, the formwork of the lower side of the lower floating plate is removed, and then the formwork of the water dropper is removed, so that the water dropper is integrally poured and formed on the lower side of the lower floating plate.

[0085] S2, pipeline installation construction steps:

[0086] S2.1, drainage vertical pipe, the drainage vertical pipe passes through the first water stop joint from the lower floating plate to the upper floating plate, and is sealingly connected with the pipe opening of one of the second water stop joints;

[0087] Among them, the diameter of the first water stop joint is two grades larger than the diameter of the drainage vertical pipe, and the flow guide gap is formed between the first water stop joint and the drainage vertical pipe. The flow guide gap and the outer wall of the drainage vertical pipe are used for guiding the water in the upper floating window hidden cavity in the building and the water outside the water supply pipe from top to bottom along the flow guide gap and along the outer wall of the drainage vertical pipe to the air conditioner site below, and the accumulated water is volatilized on the ground of the air conditioner site or is guided to the outside of the building, so as to avoid the retention of accumulated water in the floating window hidden cavity of each floor. And the flow guide gap is used for the observation hole or tool extension space for later maintenance;

[0088] S2.2, install the movable joint, and the two ends of the movable joint are sealingly connected with the drainage vertical pipe;

[0089] S2.3, water supply tee, the water supply tee is arranged in the floating window hidden cavity below the upper floating plate; the vertical two side pipe openings of the water supply tee are sealingly connected with the two ends of the drainage vertical pipe of the next floor;

[0090] S2.4 Water supply pipe, the diameter of the water supply pipe is smaller than the second water stop joint, one end of the water supply pipe passes through and extends out of the other second water stop joint, and the other end of the water supply pipe is sealed and connected to the horizontal pipe opening of the water supply tee.

[0091] In order to facilitate the drainage of water from the outside of the water supply pipe and prevent water leakage from forming in the concealed cavity of the bay window, the included angle between the two ends of the water supply pipe is controlled to be greater than 90 degrees during installation. This is to guide the condensate through the water supply pipe to the water supply tee, and the water supply tee then guides the condensate to the drainage riser. This prevents condensate leakage after long-term use of the pipe or condensation on the surface of the water pipe due to the temperature difference between the condensate and the environment, which would cause water to drip in the concealed cavity of the bay window.

[0092] When applying this method, two 45-degree bends can be used to allow the water supply pipe to reach the horizontal section of the water supply tee, and to connect the vertical section of the water supply pipe and the water supply tee at an angle. This makes it easier for water on the outer wall of the water supply pipe to flow to the outer wall of the drainage riser, preventing water droplets from falling into the concealed cavity of the bay window.

[0093] S2.5 After the water supply pipe is installed to the second water stop and the water supply tee, at the air conditioner location, on the upper side of the floating plate, use weather-resistant sealant to fill and seal the gap between the inner wall of the second water stop and the outer wall of the water supply pipe.

[0094] S3. Waterproofing steps for floors and walls: S3.1. For the floors and walls of air conditioner unit locations and bay window cavities, use an angle grinder and wire brush to clean the laitance of the concrete base layer, focusing on cleaning the pipe roots penetrating the wall and the inside and outside corners to prevent water from seeping in and accumulating at the pipe roots and inside and outside corners.

[0095] S3.2. Use cement mortar plastering to set a 2% drainage slope on the ground at the air conditioner unit location facing the entrance; use cement mortar plastering to set a 2% drainage slope on the lower side of the bay window cavity from all sides towards the first waterstop section.

[0096] S3.3 Apply waterproof coating to the pipe roots and corners of the air conditioner unit and bay window cavity; extend the waterproof coating on the upper part of the window slab up to 300mm high on the surrounding walls and up to the PVC water pipe to prevent rainwater from seeping into the room or cavity.

[0097] S3.4. Seal the bay window cavity with a brick wall, make a 200mm high concrete wall pad at the bottom of the brick wall, and apply waterproof coating within a 300mm high range at the bottom of the cavity to prevent water from seeping into the room when a small amount of water accumulates at the bottom.

[0098] S4. After the waterproofing of the floor and walls in step S3 is completed, install louvers at the entrance of the air conditioner unit. The louvers are installed in a detachable manner behind the drip groove to enclose the entrance of the air conditioner unit and prevent rainwater from the typhoon from entering the air conditioner unit.

[0099] S4.1, a drainage gap is left between the lower side of the louver and the ground of the air conditioner site.

[0100] S5, waterproof step of air conditioner installation: S5.1, remove the louver, install the air conditioner outdoor unit on the air conditioner site, and the fan of the air conditioner outdoor unit faces the air inlet of the air conditioner site;

[0101] S5.2, wrap the condenser copper pipe of the air conditioner with an ointment heat preservation pipe, and wrap it with two layers of air conditioner straps to prevent the ointment heat preservation pipe from loosening or falling off during use, and wrap the drainage pipe with the air conditioner strap close to the air conditioner indoor unit, and the condenser copper pipe and the drainage pipe are taken out from the indoor air conditioner reserved sleeve to the air conditioner site, and the condenser copper pipe is connected with the air conditioner outdoor unit, and the drainage pipe is sealed with the water supply pipe.

[0102] S5.3, wrap a layer of air conditioner strap on the outside of the drainage pipe from the air conditioner reserved sleeve to the extension section of the water supply pipe, which is used to prevent the extension section of the drainage pipe from aging and leaking.

[0103] S5.4, after the condenser copper pipe and the drainage pipe pass through the air conditioner reserved sleeve, fill the heat preservation foam glue in the air conditioner reserved sleeve on the side of the bedroom, and fill the mildew-proof sealant outside the foam glue; fill the weather-resistant glue in the air conditioner reserved sleeve on the side of the air conditioner site.

[0104] As one of the optional embodiments,

[0105] In the S1 step, when embedding the first water stop section and the second water stop section connected with the drainage vertical pipe, it is necessary to position by wire hanging, for ensuring the coaxiality and perpendicularity of the first water stop section and the second water stop section, so that there is a gap between the outer wall of the installed drainage vertical pipe and the inner wall of the first water stop section, avoiding the water guided by the drainage vertical pipe from contacting the inner wall of the first water stop section and spreading to the lower floating plate.

[0106] The present application effectively solves the core problems of insufficient drainage power, material moisture failure, low construction precision and difficult maintenance in traditional air conditioner condenser pipe concealed installation, and can effectively improve the construction efficiency while ensuring the construction quality, avoid the problem of water accumulation in the interior of the bay window cavity and the leakage of the pipeline structure, and has the following obvious advantages: (1) the drainage efficiency is improved significantly: through the double-path drainage design, the gap between the outer wall of the drainage vertical pipe and the inner wall of the first water stop section forms an external natural drainage channel, combined with the internal main drainage path of the drainage vertical pipe, realizing "double-channel drainage". Even if the vertical pipe is blocked, the external gap can still guide the water, avoiding water accumulation in the bay window cavity and preventing the bay window wall from being affected by moisture and mildew.

[0107] The optimization of gravity drainage is performed by increasing the diameter of the first water stop section, so that the diameter of the first water stop section is greater than the diameter of the drainage vertical pipe by two levels, to ensure that the flow guide gap is sufficient, so that the accumulated water in the dark cavity of the bay window and the water outside the water supply pipe can flow downward along the flow guide gap and the outer wall of the drainage vertical pipe to the air conditioning position below, and evaporate the accumulated water through the ground of the air conditioning position or guide the accumulated water to the outside of the building. Moreover, the drainage vertical pipe is used to guide and drain the water outside the water supply pipe, directly solving the problem of water droplets on the surface of the water supply pipe due to condensate water supercooling or water leakage of the water supply pipe, which causes water droplets on the dark cavity of the bay window. Therefore, the phenomenon of excessive humidity in the dark cavity of the bay window and the wall caused by water accumulation in the dark cavity of the bay window is avoided. At the same time, the natural gravity slope is combined to make the water in the dark cavity of the bay window flow out along the flow guide gap, so that efficient drainage can be achieved without additional drainage power, and the problem of insufficient drainage power of the traditional hidden pipe is also solved.

[0108] (2) The moisture-proof and sealing performance is enhanced: the first and second water stop sections are pre-buried by the concrete pre-buried process, and are tightly attached to the upper and lower floating plates to avoid joint cracks. The pre-buried positioning is accurate, and the sealing connection process of the drainage vertical pipe and the air conditioning condensate water drainage pipe is combined by adhesive connection. The sealing connection process effectively prevents the leakage of air conditioning condensate water and internal drainage of the drainage vertical pipe to the outside, avoids the error of the installed pipe in the later stage, reduces the service life of the pipe, and avoids pipe leakage.

[0109] Compared with the traditional method of installing the water stop section by punching holes in the later stage, the cracks at the joint of the first and second water stop sections and the installation hole of the upper and lower floating plates will reappear due to the cyclic stress of thermal expansion and cold contraction in the later stage, even if the cracks are filled with crack filling agent. Water accumulation is easy to occur in the interior of the floating plate through the cracks, and the pre-buried water stop section can make the water stop section and the floating plate concrete integrated, and the joint is complete without cracks. The water accumulation in the interior of the bay window dark cavity, the water accumulation at the air conditioning position, and the water flowing along the surface of the drainage vertical pipe into the interior of the floating plate concrete are avoided, so as to prevent the increase of the humidity in the interior of the bay window dark cavity and the mold growth of the wall of the bay window dark cavity.

[0110] The flexible connection of the drainage vertical pipe is achieved by setting a live joint in the drainage vertical pipe in the air conditioning position. The live joint has good sealing performance, is easy to install and disassemble, is convenient for maintenance of the drainage vertical pipe in the later stage, and saves maintenance cost.

[0111] (3) Construction precision and efficiency are improved: standardized pre-buried positioning: the water stop is pre-buried before the concrete pouring, the flange side is accurately aligned with the lower side of the floating plate, and the pipe opening height is ensured to be consistent through the template positioning technology, such as "the pipe opening of the first water stop is flush with the upper side of the lower floating plate, and the pipe openings of the two second water stops are higher than the upper side of the upper floating plate", thereby significantly reducing the positioning error of manual hole opening and the installation height error of the water stop compared with the non-pre-buried later hole opening, and the combination strength of the pre-buried water stop and the floating plate concrete is higher.

[0112] Modular installation: by using standardized interfaces for water supply tees, unions and other components, only glue sealing connection is needed in sequence during construction, the operation process is simplified, the dependence on worker skills is reduced, and the reliability of the connection is ensured, making it easier to implement standardized construction, resulting in better construction effect and reducing the proportion of pipe structure water leakage in the building bay window hidden cavity.

[0113] (4) Breakthrough in maintenance convenience: multifunctional use of flow guiding gap: the gap between the drainage vertical pipe and the first water stop has flow guiding and maintenance functions, as the size of the flow guiding gap is large, a flashlight or a camera can be inserted through the gap to observe the blockage and water accumulation of the bay window hidden cavity, or an endoscope can be used to observe the situation in the bay window hidden cavity, and when repair action is needed, a water suction pipe can be inserted to clean directly without damaging the back brick wall of the bay window hidden cavity, so that quick repair can be performed.

[0114] Layered independent maintenance of bay window hidden cavity: the drainage vertical pipes of the bay window hidden cavity of each floor in the building are independently connected, and when a single floor fails, only the corresponding union needs to be disassembled for maintenance, avoiding the drawbacks of traditional hidden pipes that "pull one hair and the whole body moves", reducing the maintenance and repair time, improving the maintenance efficiency and reducing the maintenance cost.

[0115] (5) Long-term cost reduction: reduce maintenance frequency: the double-channel drainage structure can effectively reduce the probability of blockage of the drainage vertical pipe inside and the flow guiding gap, combined with moisture-proof materials and sealing technology, the humidity in the bay window hidden cavity can be kept within a reasonable range, thereby avoiding the problem of moisture return and mold growth on the wall side of the bay window hidden cavity, significantly prolonging the service life of the wall surface and reducing the long-term decoration cost; and the service life of the pipeline is also significantly prolonged, reducing the later maintenance cost.

[0116] Energy saving and environmental protection: the flow guiding gap relies on natural gravity to drain water from the bay window hidden cavity, and the condensation or seepage on the surface of the drainage vertical pipe relies on gravity, without the need for energy-consuming equipment such as water pumps, meeting the requirements of green building.

[0117] The parameters of the above-mentioned various standard pipe fittings, the first water stop, the second water stop, the drainage vertical pipe, the union, the water supply tee and the water supply pipe are all PVC pipe products.

[0118] The first water stop is a PVC water stop with a diameter of 110 mm; the two second water stops are PVC water stops with a diameter of 50 mm; the drainage vertical pipe is a PVC drainage pipe with a diameter of 50 mm; the union is a PVC union with a diameter of 50 mm; the water supply tee joint is a PVC tee joint with a diameter of 50*50*20 mm; and the water supply pipe is a PVC water pipe with a diameter of 20 mm.

[0119] The second embodiment of the installation and construction method of the air conditioner condensing pipe hidden cavity is as shown in the figure Figure 5 As shown in the figure, the difference between this embodiment and the first embodiment is that a water guide plate is further included; the water guide plate is hung at the vertical section of the water supply pipe penetrating into the second water stop and at the drainage vertical pipe below the water supply tee joint, and is used to guide the water on the outer wall of the water supply pipe to the outer wall of the drainage vertical pipe, so as to avoid the formation of dripping leakage in the bay window hidden cavity when the water supply pipe leaks.

[0120] In application, when the water supply pipe appears condensation due to the low temperature of the air conditioner condensate or appears leakage, the water on the surface of the water supply pipe or the leaked water can be reliably guided to the drainage vertical pipe, and is guided to the air conditioner position along the outer wall of the drainage vertical pipe to be drained or evaporated, so that the bay window hidden cavity, the lower bay window plate and the wall body are kept dry, thereby controlling the humidity of the wall body of the bay window hidden cavity, avoiding the wall surface of the bedroom from appearing wall skin peeling, wall skin explosion or wall skin mildew, and further preventing the problems of water source leakage and water storage in the bay window hidden cavity in a more reliable manner.

[0121] The technical features of the above embodiments can be combined in any manner. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described.
