Summan;:
The present invention, titled "Aqua Zone," pertains to an attachment
system designed for air conditioner outdoor units to reduce the
temperature of the hot air emitted, thereby improving energy efficiency
and mitigating environmental heat build-up. The system employs a
water-based cooling mechanism using highly absorbent clay cylinders,
which cool down the air passing through them before it is released. The
system comes in two models: one with a water tank for enclosed spaces
Another without a tank, relying on a direct water connection,
suitable for open environments.
The Aqua Zone system comprises a cuboidal aluminium cage with
perforated sides attached to the outdoor AC unit, housing the clay
cooling tubes. A water sprinkler system cools these cylinders, with
excess water collected and recycled via a slab beneath the structure,
ensuring efficient usage. Sensors are integrated into the system to
monitor air temperature and water levels, providing users with real-time
data and notifications through a connected mobile app for performance
monitoring.
This invention aims to provide an eco-friendly solution to reduce heat
emissions from air ·conditioning units, particularly in densely populated
urban areas. By recycling water and enhancing the cooling efficiency of
air conditioners, the Aqua Zone system contributes to reduced power
consumption and a more sustainable approach to managing the thermal
impact of AC systems
Objectives:
The primary objective of this invention is to design and develop a
compact, efficient attachment system for air conditioning (AC) outdoor
units that effectively reduces the temperature of the hot air released.
This cooling mechanism is intended to improve the energy efficiency of
AC units while simultaneously mitigating the heat island effect in urban
areas. The system is engineered for seamless integration with existing
AC units, ensuring minimal disruption during installation and everyday
operation.
Another key objective is to offer two distinct models, catering to
different environmental conditions. One model will feature an
integrated water tank, making it suitable for confined or enclosed
spaces, while the tank-less model will be optimized for open spaces with
direct water supply access. By providing these options, the invention
will deliver versatility, ensuring that users can select the model best
suited to their unique environment and AC placement.
Water efficiency is a crucial focus for this invention. The system employs
water-absorbent clay sand cylinders to cool the expelled air from the AC
unit. The excess water is captured and recycled through an integrated
collection slab, reducing water wastage and ensuring sustainable
operation. The system's design aims to maximize cooling efficiency
while minimizing water consumption, contributing to environmental
conservation.
Monitoring and ease of use are also essential objectives. The
system is equipped with sensors that track both the air
temperature and water levels, providing real-time data to users
through a connected mobile application. This feature ensures
that the system operates at optimal performance, giving users
peace of mind through automated notifications when
maintenance, such as refilling the water tank, is required.
Another objective of the invention is to enhance user experience by
ensuring a long-lasting and durable system. The materials selected,
including aluminium for the cage and clay sand for the cooling tubes,
are chosen for their resilience and thermal properties, ensuring the
system remains functional and efficient over extended periods of use,
even in challenging climates. The invention is also designed to operate
with minimal noise, contributing to user comfort.
Finally, the invention aims to contribute to reducing the overall energy
consumption of air conditioners by lowering the external temperature
around the outdoor unit. By doing so, the system reduces the strain on
the air conditioner's compressor, potentially lowering the unit's power
consumption and extending its lifespan.

Figure 5 -Workflow
This figure presents a diagram of the Aqua Zone, an air-cooling system
using cooled earthen pots to lower the temperature of hot air discharged
from an air conditioning (A C) outlet. The process begins with the hot air
being routeLi through the Aqua Zone, where it passes over cooled
earthen pots filled with water. As the air interacts with the water, it cools
down. The water collected from the cooling process is then pulled out by
a motor and stored in a compartment. The normalized air, having
decreased by approximately l5°C compared to outdoor air, is then
released.
Detailed explanation of the invention:
Aqua Zone is an innovative attachment designed to enhance the
efficiency of air conditioning systems by reducing the temperature of the
hot air expelled from the outdoor unit. This invention employs a unique
combination of water-based cooling mechanisms to mitigate the energy
loss typically associated with traditional AC units.

Core Technology
At the heart of this invention is a cuboidal aluminium cage that
envelops the outdoor AC unit. This structure features strategically
perforated front and back faces to allow optimal airflow while housing
essential cooling components. The core cooling mechanism consists of
cylindrical clay sand tubes, which are known for their high water
absorbency and effective cooling properties.
Activation Mechanism
The Aqua Zone operates autonomously, utilizing a water sprinkler
system mounted atup the aluminium cage. In the model equipped with
a water tank, water flows from a 20-liter tank to a motor, which pumps it
through the sprinkler system. For models without a tank, water is drawn
directly from a main source, controlled manually to maintain optimal
cooling performance.
Cooling Process
When the water is sprayed onto the clay sand cylinders, it cools down,
allowing the hot air released from the outdoor unit to pass through these
cooled structures. This process signific~ntly reduces the temperature of
the air before it is expelled into the
environment, enhancing overall AC efficiency and performance.
Water Management
In the model. with a water t<Jnk, an integrated sensor alerts users when
the water level is low, ensuring continuous operation without the need
for frequent checks. In the alternative model, the direct connection to a
water source allows for a steady supply, suitable for installations in open
environments.
Environmental Considerations
A water collector slab positioned beneath the clay cylinders captures
excess water, facilitating recycling and reducing waste. This feature9

emphasizes the invention's commitment to environmental" sustainability
while improving the efficiency of the air conditioning system.
Monitoring and Data Management
The Aqua Zone attachment includes a dedicated application that allows
users to monitor water levels and view air temperature data. This
feature empowers users to manage the system efficiently and optimize
performance based on real-time conditions.
