HEAT LOAD REPORT

AIR DISTRIBUTION

• Ceiling suspended AHU is selected to distribute air & Comfort condition is ,

• 77°F with 50% RH, ADP is 54°F & 7500 CFM per AHU.

• Chilled water inlet 7°C & outlet is 15°C.

• VCD are placed at beginning of each duct.

• Backward curved aero-foil blade centrifugal fan for AHU.

DUCT PRESSURE DROP ANALYSIS

• Pressure drop is due to bends and head.

• Based on pressure drop in Critical path AHU fan is selected.

• For efficient air flow through duct, pressure loss should be minimum.

CHILLER PLANT

• Total building load 104.4TR

• Diversity factor is 100%

• Water cooled screw chiller of 104.4TR

• Counter flow cooling tower for 104.4TR capacity.

PLUMBING

• 1% slope for sanitary pipes

• No 90°bends only Y fittings

ELECTRICAL SYSTEM

• Cables are sized and selected based on current flow by using standard catalogues

• Ladder type cable trays are used

• As per NBC lighting fixture is at 7 feet from floor

FIRE FIGHTING

• Fire fighting system is designed as per NBC standards for commercial building

• Pipes are sized based on number of sprinklers

• Sprinklers are placed effectively to cover entire area of the building

CO-ORDINATION OF ALL FLOORS

INTERFERENCE CHECK

• Interference check between MEP systems is performed

• Clashes are highlighted by ID

CLASH DETECTION AND SOLUTION

CLASH OF FIRE FIGHTING PIPE & DUCT

CLASH SOLVED BY MOVING FIRE FIGHTING PIPE

ANNOTATION

• Labels are created to annotate duct size and flow rate

• Diffusers are tagged with neck size and CFM

CREATION OF FAMILIES

• Designing of AHU with specified duct sizes and pipe connectors

• Designing of Air terminal with specified neck sizes
