This document discusses air conditioning ducts. It describes the functions of ducts as transmitting air from air handling units to conditioned spaces and properly distributing air. Ducts are classified by velocity, pressure, and air type. General design rules include conveying air directly to save space and power, avoiding sudden changes in direction, and keeping the aspect ratio close to 1. Factors affecting duct design include heat gain/loss and friction. Common duct materials are GI sheet, aluminum, stainless steel, and fiberglass. Dynamic losses occur due to changes in air direction or velocity. The two main duct design methods are the velocity reduction method and equal pressure drop method.

HVAC is typically responsible for around 40% of the energy consumption in a building. Frequently, this is the largest energy consuming type of equipment on a site and can therefore provide significant scope for saving energy and money. This fact sheet covers common types of HVAC and will guide you in the right direction to identify energy efficient HVAC initiatives.

Heat Load Calculations and Duct Design for Commercial Building G 2ijtsrd
The modern commercial or office building consists of the HVAC system which is Heating, Ventilation, Air conditioned. In this report, well going to identify the purpose and goals of HVAC system, describe HVAC types, describe HVAC parts and describe how this part works together or its working cycle. outsides to air conditioning there are ventilation systems like ceiling fan, fresh air supply and exhaust fan where ceiling fan is used is used to ventilate the air with rotating blades and exhaust fan is used to displace the inside air to the outside environment, fresh air supply is used to displace the inside air to the outside environment by supplying fresh air from the outside air. And also the design of duct by using the heat load calculations based on that how much amount of air to be carried out to gain the required cooling inside the area is determined and also creating the comfortable zone for the humans.

Immunizing Image Classifiers Against Localized Adversary Attacksgerogepatton
This paper addresses the vulnerability of deep learning models, particularly convolutional neural networks
(CNN)s, to adversarial attacks and presents a proactive training technique designed to counter them. We
introduce a novel volumization algorithm, which transforms 2D images into 3D volumetric representations.
When combined with 3D convolution and deep curriculum learning optimization (CLO), itsignificantly improves
the immunity of models against localized universal attacks by up to 40%. We evaluate our proposed approach
using contemporary CNN architectures and the modified Canadian Institute for Advanced Research (CIFAR-10
and CIFAR-100) and ImageNet Large Scale Visual Recognition Challenge (ILSVRC12) datasets, showcasing
accuracy improvements over previous techniques. The results indicate that the combination of the volumetric
input and curriculum learning holds significant promise for mitigating adversarial attacks without necessitating
adversary training.

Hybrid optimization of pumped hydro system and solar- Engr. Abdul-Azeez.pdffxintegritypublishin
Advancements in technology unveil a myriad of electrical and electronic breakthroughs geared towards efficiently harnessing limited resources to meet human energy demands. The optimization of hybrid solar PV panels and pumped hydro energy supply systems plays a pivotal role in utilizing natural resources effectively. This initiative not only benefits humanity but also fosters environmental sustainability. The study investigated the design optimization of these hybrid systems, focusing on understanding solar radiation patterns, identifying geographical influences on solar radiation, formulating a mathematical model for system optimization, and determining the optimal configuration of PV panels and pumped hydro storage. Through a comparative analysis approach and eight weeks of data collection, the study addressed key research questions related to solar radiation patterns and optimal system design. The findings highlighted regions with heightened solar radiation levels, showcasing substantial potential for power generation and emphasizing the system's efficiency. Optimizing system design significantly boosted power generation, promoted renewable energy utilization, and enhanced energy storage capacity. The study underscored the benefits of optimizing hybrid solar PV panels and pumped hydro energy supply systems for sustainable energy usage. Optimizing the design of solar PV panels and pumped hydro energy supply systems as examined across diverse climatic conditions in a developing country, not only enhances power generation but also improves the integration of renewable energy sources and boosts energy storage capacities, particularly beneficial for less economically prosperous regions. Additionally, the study provides valuable insights for advancing energy research in economically viable areas. Recommendations included conducting site-specific assessments, utilizing advanced modeling tools, implementing regular maintenance protocols, and enhancing communication among system components.
2. Functions of Duct
The function of duct is to transmit the air
from air handling unit to the space to be air
conditioned.
The conditioned air must be properly
distributed to provide comfort zone
conditions.
Duct systems are also used to bring cooled or
warm air to the proper distribution points
where several rooms are to be conditioned.
3. Classification of ducts
According to the velocity of duct : Low velocity and
higher velocity duct. When velocity of air is upto 750
m/min and more than 750 m/min.
According to pressure : Low pressure, high pressure
and medium pressure. When static pressure is less
than 50 mm of water, 50-150 mm of water and 150-
250 mm of water.
According to type of air : Supply air duct, return air
duct and Fresh air duct.
4. General rules for duct design
1. Air should be conveyed as directly as possible to save
space, power and material
2. Sudden changes in directions should be avoided.
When not possible to avoid sudden changes, turning
vanes should be used to reduce pressure loss
3. Diverging sections should be gradual. Angle of
divergence ≤ 20 degree.
4. Aspect ratio should be as close to 1.0 as possible.
Normally, it should not exceed 4
5. Air velocities should be within permissible limits to
reduce noise and vibration
6. Duct material should be as smooth as possible to
reduce frictional losses
5. Factors affecting design of duct
1. Heat gain or heat loss from duct
2. Aspect ratio : It should not be more than 8
for rectangular duct.
3. Duct Friction
4. Type of fitting
7. What is dynamic losses in duct?
Whenever there is a change in direction or
velocity in the flow through the duct is known
as dynamic loss.
It is due to:
1. Change in direction of flow through bends,
elbows
2. Sudden change in area due to enlargement,
contraction etc.
9. Velocity reduction method
In this method, velocities in the ducts are assumed
that they decreases as the flow proceeds.
The pressure drops are calculated for these velocities
for respective branches from main duct.
The pressure at the outlet is adjusted by dampers.
This is easiest method and velocities can be adjusted
to avoid noise.
In this method, considerable experience is required for
selection of velocities.
10. Equal pressure drop method
In this method, the size of duct is decided to
give equal pressure drop per meter length in
all ducts.
If layout of duct is symmetrical and same
length then this method gives equal pressure
drop and no damper is required.
In case run at different lengths then shortest
will give minimum pressure drop and require
heavy damper at outlet.
