Duct quiet zones utilization for an enhancement the acoustical air-condition...IJECEIAES
This paper investigates the duct’s noise distribution pattern due to the heating, ventilation, and air conditioning systems. This study is considering the longitudinal sound wave distribution that can permit a higher reduction of these heating, ventilation, and air conditioning systems duct noise. The proposed technique is depending on the lowest sound pressure level points in the duct or duct quiet zones. Moreover, each heating, ventilation, and air conditioning systems duct has several quiet zones, depending on the sound pressure level of the fan noise source and the duct length as well as the duct diameter. Furthermore, the noise standing wave has a wavelength (λ) which is the distance between two successive quiet zones. This work utilizes orthogonal acoustical noise with the standing wave via feed-forward control speakers. This system confirmed that the distance (λ) is linearly proportional to the duct source noise level. This system noise reduction enhancement has been fulfilled by installing further noise feed-forward control speakers at different duct quiet zones. The system simulation results were displaying satisfactory agreement with the field experimental results.

ABSTRACT
Electricity exists in a form that is useful to exploit, however, it will also be important to install electricity as
efficiently as possible, and design of the power distribution system should be convenient so as to minimize
power losses. This paper analyses the electrical service design of a Storey building using the lumen method for
the lighting calculations. The purpose of this work is to present a suitable approach to electrical services design
based on the provision of the Institution of Electrical Engineers (lEE) Regulations, which includes lighting,
power, distribution boards schematics. The results of the whole analysis and design was illustrated with
AutoCAD application. This work gives a direct approach from design of the electrical services to the installation
stage. The results of the calculations in the design helps the designer to make vital decisions such as types of
luminaries, sizes of cables and nominal ratings of protective devices required by each circuit and by the entire
installation in line with appropriate standards and regulations.

“After being the most listed dog breed in the United States for 31
years in a row, the Labrador Retriever has dropped to second place
in the American Kennel Club's annual survey of the country's most
popular canines. The French Bulldog is the new top dog in the
United States as of 2022. The stylish puppy has ascended the
rankings in rapid time despite having health concerns and limited

INTRODUCTION
In a distribution system there are wiring rules which briefly states: [2]-Each power line holds certain amount of wattage,
(Normal loading is 1200 Watt or less and maximum loading is 1500 watt).- Care about each line length to minimize the cost
for each by connecting floor parts which are undependable on each other and near to each other.
- The acceptable number of lighting wires is 5 or 6 lines for each floor.
- Each lighting wire should be hidden in the wall by using certain tubes.
- Each lighting switch should be in obvious place;- Distribution banal place should be in a place which achieve the most economical wires length and not deform the wall
view.
Lighting control is one of the basic functions of KNX Protocol. A big advantage of KNX is its high level of flexibility.
Accordingly, changes to the lighting and lighting Control in terms of its function, usage and floor
plan can usually be realized by simple reprogramming.
There are three basic control types: [5]
1. Switching all types of luminaries via switch actuators
2. Dimming of certain luminaries via universal dimmer actuators
3. Dimming of certain luminaries via Light Controllers/Switch/Dim Actuators
-Switch actuators: are been used with KNX unlike conventional switching via light switches or pushbuttons with installation
relays. Switch actuators are so-called intelligent relays.
-Dimming actuators: Dimming options for the lighting are important and are an ever more desired function.
-Two important factors play an important role here:
1. Comfort, e.g. pleasant lighting while dining that suits the situation and mood
2. Cost-effectiveness, power consumption and cost reduction through:
– Dimming of the lighting to suit the incidence of external light
– Extended service life of the luminaries through reduced intensity of the switch on brightness
– Reduced brightness for different area usages, e.g.
A different level of brightness is required than during training sessions.
2. Classification of Studying the Distribution System:
1- Distribution system in Wedding hall& Office& Area9 in ground floor.
2-Distribution system in Area3& Women ablution & Entrance & Conference & women bathrooms in ground floor.
3-Distribution system in praying hall for women& Stairs in ground floor.
4-Distribution system in Wedding hall2& Wedding hall3 in First floor.

7. Toward Understanding the Smart Home Automation Concept Using KNX Protocol
There are main steps to adjust KNX Protocol:1- First step:
1.1 -Connecting all loads which have the same controlling action.
1.2-Determine the most suitable
actuator according to reliability and cost.
1.3-Refering each line to its channel of its actuator.
(EXP: Sw3/4: means this line will be connected to the switch actuator no. 3 at it’s forth channel).
2-Second step:
2.1- After determining the most reliable actuators and arranging it in the distribution panel.
2.2-Connect each load to the channel of its actuator.
2.3-Determine
the
suitable
power
supply
to
connect
it
to
the
panel.
(By assuming that each actuator takes 10 MA (ref), and the rating of the power supplies ranges is (160 MA, 230
MA, 640 MA),
Hint: It is ok to connect to power supplies in the same panel for one cable but if the length of this cable not less
than 200 M.
2.4- Only one cable is exit from the panel passing by all switches and sensors as In Fig. A*-4
Hint: this connection might be in tree, line or star but never be loop.
The order, the signal will rotate in the loop and will not reach the actuator).
Third step:
Inserting a description for the switches operation as shown in fig. A*-7.

CONCLUSIONS
Smart homes are for sure an upcoming challenge. If research works trend to explore and share promising results
concerning this concept, adoption by industry would imply many efforts.
We have presented in this article our responses to adoption efforts. We think that using the KNX model, in particular the
Easy Mode specifications, eases the integration of existing technologies and services into a single, open and standardized
system. Even more, this model can ease market adoption, by abstracting home automation hardware and focusing on end
user services.
By applying the wiring rules according to the Egyptian code and IEE Wiring regulation, this design is considered as a safety
and economical design.
Applying KNX Protocol in this Mosque drops the total cost, but actually this save in power and for sure in money in small
building like Mosque or either a house isn’t as effective as in large buildings like mall for example.
