Description

A System for Water Recycling in an Air ConditionerField of the Invention

[0001] The present invention relates to a system for reusing the water from the AC. More particularly, the present invention relates to a system for water recycling in an air conditioner.Background of the Invention

[0002] Generally, Air conditioners (ACs) generate significant amounts of water as condensate, which is often discarded, contributing to water wastage and environmental concerns, particularly in regions facing water scarcity. Traditional AC systems lack efficient means for recycling this water, and existing solutions that attempt to reuse condensate frequently face various limitations, such as inadequate control over water levels and mist production, high energy consumption, and insufficient purification measures. These systems often require manual monitoring and intervention to prevent overflow, leading to inefficiency, increased maintenance needs, and user inconvenience.

[0003] In many cases, traditional misting systems for water recycling consume excessive power, particularly when they attempt to operate at reduced water levels. This not only increases energy costs but also shortens the lifespan of the misting device due to continuous high-load operation. Furthermore,existing systems lack effective methods for controlling mist production based on water availability, resulting in suboptimal water conversion efficiency.

[0004] Another critical issue is the potential contamination of recycled water, which, if left untreated, can introduce impurities that impact air quality or cause mechanical wear. Current recycling systems often overlook purification, allowing for the possibility of unclean water being reintroduced into the AC system, which can degrade performance and potentially compromise the health of users exposed to the air.

[0005] Overflow prevention is another challenge for these systems.Many lack automated alerts or control mechanisms to signal when water levels approach critical thresholds, leading to overflow and potential water spillage. This not only increases maintenance demands but can also risk be damaging the AC unit itself. In some cases, users are required to manually monitor and shut off the compressor to prevent overflow, a process that is time-consuming and inconvenient.

[0006] Therefor there is a need of a system for water recycling in an air conditioner that overcomes all the problems of the existing prior art.Objects of the Invention

[0023] Figure 1 shows a schematic view of a system for water recycling in an air conditioner in accordance with the present invention;Detailed Description of the Invention

[0024] The following is a detailed description of embodiments of the disclosure depicted in the accompanying drawings. The disclosed embodimentsare merely exemplary of the invention, which may be embodied in various forms. The embodiments are in such detail as to clearly communicate the disclosure. However, the amount of detail offered is not intended to limit the anticipated variations of embodiments on the contrary, the intention is to cover all modifications, equivalents, and alternatives falling within the and scope of the present disclosure as defined by the appended claims.

[0025] The present invention relates to an electronic device for water recycling in an air conditioner. The electronic device includes multiple sensor that detect the level of the water within the water storage tank. The electronic device enhances the cooling effect from the condensate of the air conditioner.

[0026] In the following description, numerous specific details are set forth in order to provide a thorough understanding of embodiments of the present invention. It will be apparent to one skilled in the art that embodiments of the present invention may be practiced without some of these specific details.

[0027] Referring now to figure 1 of a system (100) for water recycling in an air conditioner in accordance with the present invention is illustrated. The system (100) for water recycling in an air conditioner (150) is hereinafter referred to as “the system (100)”. The system (100) includes a water tank (110) and a piezoelectric ultrasonic transducer (130).

[0028] The system (100) is integrated within the air conditioner(150) attached to the water output of the air conditioner (150). The system (100) stores the condensate / water of the air conditioner (150) and prevent direct disposal of the air conditioner (150) condensate into the cooling area. In the present embodiment, the system (100) is rectangular enclosure attached adjacent to the air conditioner (150), connected to the air conditioner (150) water outlet and cooling outlet. In an embodiment, the system (100) may be completely integrated within the air conditioner (150). It is obvious for the person skilled in the art to configure the system (100) with any shape or position as per the requirement.

[0029] The air conditioner (150) includes a display (154) to show working status of the system (100). The display (154) shows all the data of the system (100) to the user. It is obvious for the person skilled in the art to configure any alternative indicative element to alert the user.

[0030] The water tank (110) is integrated within the system (100).The water tank (110) stores the water coming from the water outlet of the air conditioner (150). The water tank (110) is in cylindrical shape, it is obvious for the person skilled in the art to make the water tank (110) with shape and size and material. The water outlet disposes the water into the water tank (110), the water tank (110) includes a base (not shown) at the bottom. The base is made of the jamun wood, the base is flat thick circular plate placed on the bottom of the water tank (110). The jamun wood is beneficial for long term water storage, as the water tank (110) may store the water for long time. The jamun wood derived from thesyzygium cumini tree (also known as black plum or Indian blackberry), includes several natural properties that help prevent water contamination by bacteria and other microorganisms. The jamun wood contains phytonutrient which helps in keeping the water clean and also reduces environmental threats in the area. The jamun wood contains compounds such as tannins and polyphenols, which exhibit antimicrobial characteristics, effectively inhibiting the growth of bacteria, fungi, and other pathogens. The presence of tannins not only acts as a natural preservative but also creates a slightly acidic environment that is unfavourable for many microbes. Additionally, the jamun wood is notably dense and hard, making it resistant to decay and minimizing water absorption. This structural resilience reduces moisture penetration, thereby limiting the conditions necessary for microbial proliferation. When immersed in water, jamun wood gradually releases beneficial compounds that have a mild purifying effect, further discouraging bacterial growth without posing harm to humans. Moreover, it is believed that jamun wood can impart a slightly alkalizing effect to the water, which can also inhibit bacterial activity.

[0031] In an embodiment of the present invention, the j amun wood may be in a capsule shape, the user can drop some of the capsule in the water tank (110) to prevent the stored water from bacteria. It is obvious for the person skilled in the art to configure jamun wood with any shape and size as per the requirement.

[0032] Thewatertank (110) includes plurality ofwaterlevel sensor(112,114, 116) to detect the level of water within the water tank (110), a first sensor (112). The first sensor (112) is strategically positioned at the bottom of a water tank (110). The first sensor (112) is specifically designed to detect the presence of water at the lowest point within the water tank (110). When water reaches the bottom of water tank (110) and comes into contact with the first sensor (112), the first sensor (112) is activated. This activation triggers an LED indicator (not shown), which lights up to signify that water is present at the base of the water tank (110).

[0033] The illumination of the LED serves as a visual confirmation, allowing observers to easily verify that water has accumulated and is present within the water tank (110). This feature is especially useful for monitoring purposes, as it provides a clear, immediate indication that water is available in the water tank (110) without the need to physically inspect it. The design of this system ensures that as soon as the first sensor (112) detects water, it promptly alerts users via the LED, which enhances operational efficiency and helps in maintaining appropriate water levels. The first sensor (112) is an ultrasonic sensor, which detect the level of water within the water tank (110) and send the signal to a controller (140). The controller (140) then activates the LED indicator to indicate the user. In an embodiment, a float switches may be arranged within the water tank (110) to detect the water level. In another embodiment, a pressure sensor may be arranged to detect the water level, it is obvious for the person skilled in the art to configure ant alternative element to detect the presence of water within the water tank (110).

[0034] The water tank (110) further includes a second sensor (114).The second sensor (114), is positioned at 30% of the total height of the water tank (110). This location allows the second sensor (114) to detect when the water level reaches approximately one-third of the tank’s height, offering an intermediate reading of the water volume.

[0035] The second sensor (114) is programmable delay function, which means that the second sensor (114) does not react immediately when the water reaches the 30% height level. Instead, the delay allows the second sensor (114) to respond only after the water has maintained this level for a certain period, helping to avoid frequent or false triggers due to minor fluctuations in water level. This feature enables a more stable and accurate reading of the water level within the water tank (110).

[0036] Once the second sensor (114) confirms that water has reached the 30% level and the delay period is complete, the second sensor (114) sends a signal to the piezoelectric ultrasonic transducer (120). This signal prompts the piezoelectric ultrasonic transducer (120) to adjust its capacity gradually, effectively modifying its operation to match the increased water level within the water tank (110). This design supports efficient water management by enabling smooth, controlled adjustments at the 30% water level, enhancing the stability and effectiveness of the tank’s monitoring system.

[0037] The water tank (110) further includes a third sensor (116).The third sensor (116) is installed within the water tank (110) and is set to activate when the water level approaches a 60% threshold. The third sensor (116) is connected to an audible alert (154a) designed to notify the user when water reaches this specific level, giving a clear warning that the water is nearing a high point within the water tank.

[0038] By triggering an audible alert (154a), the third sensor (116) provides a preventive notification, allowing the user to take any necessary action to manage or reduce the water level before it reaches a critical level. This advance warning is particularly useful because it helps prevent the system (100) from automatically reaching the shutoff stage. If the water level were to continue rising past the 60% threshold, the system (100) triggers the shutoff of the compressor (152) to avoid overfilling the tank. By notifying the user in advance, the third sensor (116) aids in maintaining efficient operation and reducing the chances of an unnecessary compressor (152) shutoff due to high water levels.

[0039] The piezoelectric ultrasonic transducer (120), is positioned at the bottom of the water tank (110). The piezoelectric ultrasonic transducer (120) plays a key role in managing the water within the water tank (110) by converting the water into mist. The conversion process in the piezoelectric ultrasonic transducer (120) uses ultrasonic waves to create high-frequency vibrations. When activated, the piezoelectric ultrasonic transducer (120) vibrates at an ultrasonicfrequency, producing rapid oscillations that disrupt the surface tension of the water. This intense vibration causes tiny droplets to separate from the water’s surface, forming a fine mist. The high-frequency energy effectively breaks the water into small particles, which are then released as mist. This misting process allows efficient water conversion, with the transducer adjusting its misting output based on water level signals, creating a controlled release of water as a fine mist.

[0040] The capacity at which the piezoelectric ultrasonic transducer (120) converts water into mist varies based on the signals it receives from the multiple water level sensors (112, 114, and 116). Each sensor monitors a specific water level in the tank and communicates this information to the piezoelectric ultrasonic transducer (120). For example, when the first sensor (112) detects that the water level has reached the bottom of the water tank (110), the piezoelectric ultrasonic transducer (120) may be activated to begin the misting process at a lower capacity. As the water level rises and the second sensor (114) detects the 30% mark, the piezoelectric ultrasonic transducer (120) may adjust its capacity to produce mist more gradually or intensively, depending on the programmed settings. Similarly, when the third sensor (116) detects that the water is approaching the 60% level, the piezoelectric ultrasonic transducer (120) can modify its operation to accommodate the increased water level by adjusting the misting capacity accordingly.

[0041] This system (100) of varying misting capacities based on water level readings from the sensors ensures that the water is efficiently converted into mist at the right times, maintaining optimal conditions for the system and preventing overloading or inefficiencies. In the present embodiment, the piezoelectric ultrasonic transducer (120) arranged to convert the water into mist. In an embodiment, a centrifugal atomizer may be arranged to convert the water into mist. In another embodiment, a high-pressure misting nozzle may be arranged within the water tank (110). It is obvious for the person skilled in the art to configure any alternative elements to convert the water into the mist.

[0042] The system (100) further includes a mist filter (130). The mist filter (130), is arranged at the output of the water tank (110). The mist filter (130) primary function is to filter out any remaining water particles from the mist produced by the piezoelectric ultrasonic transducer (120) before the mist exits the tank. As the mist passes through the mist filter (130), the mist filter (130) captures and removes the water droplets, ensuring that only cool, dry air continues onward.

[0043] This filtered air is then directed back to the air conditioner(150), where the air gets mixed in the cooling process by providing a flow of precooled air. By filtering out water particles and recycling the water back into tank (110), this system minimizes the amount of water discharged into the environment. This process is environmentally beneficial, as it conserves water by recirculating it within the system, reducing overall water waste. Additionally, by reintroducing thecool, filtered air into air conditioner (150), the system enhances its efficiency, as it utilizes the cooled air to help maintain lower temperatures, ultimately improving the air conditioner's performance and conserving resources.

[0044] In the present invention the mist filter (130) is a zero-fog mist filter, The zero fog mist filter works by passing mist-laden air through multiple filtration stages to completely remove water droplets, ensuring only dry air exits the system (100). First, larger droplets are captured in a pre-filtration stage to prevent clogging. The air then moves through a coalescing layer, where smaller droplets combine into larger ones, which are easier to trap. Finally, an ultra-fine filtration layer captures any remaining microscopic droplets, ensuring the air is completely free of mist. The system (100) includes a drainage to the water tank to remove extra liquid directed to the water tank (100).

[0045] In an embodiment of the present invention, a vane mist eliminator may be arranged to filter the water from the mist. The Vane mist eliminators use angled plates or vanes to change the direction of airflow, forcing droplets to impact and separate from the air. The separated liquid drains away, leaving dry air. In another embodiment, a coalescing filter may be arranged to filter the water from the mist. The coalescing filters use dense, fibrous materials that cause fine droplets to merge into larger droplets, which are then easier to separate. These are efficient at capturing both liquid aerosols and solid particles. In another embodiment, a cyclonic separator or activated carbon filters with dehumidification or electrostatic precipitators or a like may be arranged to filter the water from themist. It is obvious for the person skilled in the art to configure any type of filter as per the requirement.

[0046] Therefore, the present invention provides the advantage of system (100) for water recycling in an air conditioner (150) described. First, the recycling and purifying water directly within the air conditioning process. The water tank (110) utilizes a jamun wood base to naturally purify water, enhancing water quality without chemicals, while the piezoelectric ultrasonic transducer (120) converts the water into mist. This mist is then filtered by the mist filter (130) to remove residual water particles, allowing only cool, purified air to re-enter the air conditioner (150). This closed-loop system reduces the need for additional water, minimizing waste and environmental discharge, which is particularly beneficial in regions facing water scarcity.

[0047] Furthermore, the system (100) includes advanced sensing and control mechanisms to optimize operation and conserve energy. The first sensor (112) ensures water presence, activating an LED indicator for visual monitoring, while the second sensor (114) at 30% tank capacity incorporates a programmable delay, allowing gradual adjustment of the misting capacity to conserve power during varying water levels. The third sensor (116) not only triggers an alert at 60% capacity but also works with a controller (140) to prevent overflow, allowing a buffer for extra water use. Additionally, the piezoelectric ultrasonic transducer (120) enters energy-saving mode during low water levels and switches to fullcapacity when water reaches the 30% threshold. This efficient, responsive system reduces power consumption, extends the air conditioner’s lifespan, and provides users with better control over energy use and maintenance, making it a sustainable and user-friendly solution.

[0048] While the foregoing describes various embodiments of the invention, other and further embodiments of the invention may be devised without departing from the basic scope thereof. The scope of the invention is determined by the claims that follow. The invention is not limited to the described embodiments, versions or examples, which are included to enable a person having ordinary skill in the art to make and use the invention when combined with information and knowledge available to the person having ordinary skill in the art.
