Design And Calculation Of Central Air Conditioning system (using E20-II Carrier Software ) civil And architecture engineering building Ahmed Fawzy Zaki Mohammed Elsayed Mohammed Abdel Shafi Kareem El-Sayed Sheta Salem Mohammed Abd allah Morade Mohammed Abd El-Azim Mahmoud Elshamndy Mohammed Hamdy khalifa Mohammed Galal Abd El-Hakim Azab Mohammed Shabaan Ibrahim Morsy Mahmoud Eid Mohammed Eid Mahmoud Mohammed Rashad Marwa Sabry El-gendey Mostofa Fatouh Fangary Nadia Mohammed Attia Naglaa Hamdy Eid Abd Rabbou Reda Rezk Gommaa Said Ali Mousa Solyman Shaimaa Ali Ahmed Ahmed Shaimaa Mohammed Abd Alaziz Project Tasks Step (1) Draw or study the civil and architecture building drawing sheet. Step (2) Search for the thermal properties of the building  Step (3) Determine the compass direction (North – South. etc.)  Step (4) Calculation the usage of the different places as well as numbers of people occupancy these places. Step (5): Determine the internal and external design conditions. Step (6): Estimate the thermal loads. Step (7): calculation the rate of air flow for each zone. Step (8): Design duct for the control A/C such, supply air lines and return air lines. Step (9): Determine the rectangular air ducts. Calculation the friction losses through the outlines to select air supply. Determine the outlet air capacities for each zone. Estimate the air ducts losses. Calculation the cooling coils capacities to choose the cooling unit. The bill. Introduction Air conditioning can be defined as the control of temperature, humidity, cleanliness, odor and air circulation as required by the occupants of the space. The factors that influence comfort, in there order of importance are: Temperature, humidity, air motion and the quality of the air with regard to odor, dust and bacteria. Classification of Air Conditioning Systems Air conditioning system can be classified into two main categories as follows: According to their function (comfort and processing air conditioning system). According to their construction and operating characteristics Classification of Air Conditioning Apparatus 1. Unitary equipment: Unitary equipment can be divided into:- A- Window type. B- Split type. 2. Central system components: Most large buildings, however, have their own central equipment plant and the choice of equipment depends on: 1. Required capacity and type of usage. 2. Cost and kinds of available energy. 3. Location of the equipment room. 4. Type of air distribution system. 5. Owning and operating costs. Building in the studying building for architecture and civil engineering which is located in east air shows inside the faculty of engineering (material) and has length of (69.78) m, width of (37) m, height of (35.50) m and area of (2057.86) m2. Building description The building consist of five floor in addition to the first floor. Which consist of two amphitheater and fear hall and each floor has 20 room. The bottoming floor includes a computer hall and one fear hall , Two amphitheater, and room and the third floor is consist of twenty room which includes two drawing hall. The Building Direction In the north: District separate between this building and administration building. In the south : District separate between this building and the shops. In the east: Garden In the west : AL Shahed Mustafa Hafez street Building Design Condition Latitude = 30 The dry outlet temperature = 37.7 o C from Carrier The wet outlet temperature = 26.7 o C The dry inlet temperature = 24 o C The relative humidity = 47% LOAD ESTIMATING Calculation of Heat Transfer Through Wall due to Temperature Difference Load Calculation due to Sun Load Calculation due to Ventilation Load Calculation due to Person Load Calculation duo to Light Load Calculation due to Infiltration Load Calculation due to Equipment Steps of Load Estimation Cooling Load Calculation of the Computer Room: Height wall: h =5.6 m Windows : W1 = 1.2*0.8 m2 W2 = 0.6*0.8 m2 Door : D1=1.2*1 m2 Area Calculation: Calculation of Heat Transfer Through Wall due to Temperature Difference : Q = ∑A×U×∆T External wall Uw =1/hi+1/ho+∑∂/K i Internal wall Uw =1/hi+1/hi+∑∂/K i From Table Determining the Coefficient of heat transfer the Windows and doors Windows: Single Glass = 6.08 (W/m .k) Door : Solid Wood Door Thickness (50mm) = 2.47 (W/m .k) Calculation of heat transfer through wall due to temperature difference Load Calculation due to Sun: Qsun = ∑AUΔTsun + ∑A(w/m2)glass × S.C From Table Determining the heat transfer from the sun to wall due to temperature difference. From Table Determining the Heat transfer through glass. From Table Determining the shadow coefficient Load Calculation due to Equipment: From Table Determining the heat gain due to equipment. QE = ∑Q QE = (18×200)+(1×150) = 3750 (W) Load Calculation duo to Light: QL = n×(W/lamp)×1.25 Lamp length 120 cm = 40 (w/lamp) Lamp length 60 cm = 20 (w/lamp) QL = 70.52×40 =2820 W
