Abstract
In correct B,SC project the main objective is to gain a deep
understanding of using AC Systems to serve the non-residential
buildings. Three types of non-residential buildings have been
reviewed and studied carefully, the first and second objective are to
compare between the AC performance of two praying areas buildings;
Masjed and Church. The third is to study the AC performance inside E-
test lab building.
The studied two models of Masjed and Church has been designed
and constructed to simulate these buildings using test rig circuit
consist of the two models, air handling unit, condensing unit, air duct
system, and temperature measurement system. experimental setup
on temperature measurement have been conducted to monitor the
effect of air distribution, tested on the uniformity of temperature
inside these tested models. The result have been presented during
current research.
In addition, an attention has been paid to study the AC cooling
loads inside the third of buildings (E-test lab building) using hourly
analysis program (HAP). The results of these theoretical study has also
presented in current research.
Finally, it is recommended to combine different cooling loads of
buildings together in a central unit in order to achieve the reduction
in initial and running cost. This central system will provide the building
with the most advanced and modern class, by eliminating the usage
of the large number of unitary split units, in addition to reduce the
electrical consumptions inside these building to achieve Egypt 2030
strategy.
Experimental Work
CHU. CalculationsMSJ. Calculations Methodology
The research mainly about two problems:
1.Practical visualization the supply & return air
movement of Air conditioning (AC) system in
Masjed (MASJ) and Church (CHU) – they are
representing cooling load -, By selecting the
suitable configuration of air distribution systems
among three configurations - each for MASJ. &
CHU-.
2.Practical simulation in MASJ. &CHU. heat transfer
and temperature distribution relationship between
internal loads – lighting, people, and miscellaneous
loads – and Air Handling Unit’s cooling coil (AHU)
model.
It focuses on the combination of praying areas
not only MASJ. Or CHU. but the two together
because of:
The large amount of heat dissipated in theses
spaces should be deal with in order to provide an
atmosphere suitable for the praying ritualism. The
notation of Egyptian government head for
constructing this combination of praying areas in
many cities all over Egypt, so it can provide these
spaces with the suitable AC systems to save large
expenses. The research starts from the point of
constructing a real dimensional MASJ. & CHU. each
50m*50m*15m, then to do our practical simulation
we had to scale down these dimensions by the factor
50:1 to construct a model for each space.
Materials Selection
Acrylic panels were chosen because of the advantages of
these panels mainly:
Easily Fabricated and Shaped ,Weather Resistant
(K=0.2w/m^2.k) , Lighter than Glass, Impact Resistant,
Highly Transparent ,and visibility.
Polyvinyl chloride (PVC) pipes were chosen to work as ducts
for airflow .As it is one of the most commonly used
thermoplastic polymers in the world

E-Testing Lab
proposed design for typical floor for Regional Measurement Center (RMC)
with student capacity 400 students 2 per exam per floor, and with total
building foot print area of 1600 m (L = 40 m, and W = 40 m), (all dimensions
in meters).
learn to distribute cooled air in the building and locate outlets of diffusers.
Also , Mention the importance of configure the building with refrigeration
systems to achieve the comfort and relax for people "Students" which help
and raise concentration of them during take the exam to achieve best results.
Also , Mention the methods of calculate thermal loads in any buildings and
how to cover it with suitable selected refrigeration system. Also , Mention the
types of ducts and how to select the most suitable duct system which gives
the required air flow and less losses and efficiency and cost.

Many different conceptual designs of these MEUs, MECs, and ETLs have
been reviewed and developed by during current research work as shown in
figures that present two different arrangement of E-test labs, with different
capacity upon the area of the lab and present two different arrangement of E-
test labs, with different capacity upon the area of the lab.
After conducting field visits to a number of Benha University faculties such
as Faculty of Medicine, Engineering, Specific Education and College of Physical
Education were designed MECs, MEUs, and ETLs, even using multi response
questions on printed papers, or by performing pilot E-tests, and summative E-
test, even Web based Tests (on-line exam / using clouds) or Computer based
Tests (off-line exams).
