Internship is one of the keys for understanding more deeply the concepts learned from formal education by going through practical practices adapted by industries. And this rationale brought us to National Engineering Services Pakistan NESPAK.
During our internship we have learned a lot about building services and HVAC systems. Every topic from crust to core was explained to us and this report is an overview of what we learned. Information in this report is gathered from different sources like instruction manual, project proposals, online websites and notes provided by instructors.
This document gives reader an insight of design techniques for lifts, storage tanks, and HVAC systems along with introduction to international standards. Interactive visuals provide an ease to reader for understanding cyclic process and don’t let reader to get bored as traditional technical text does.
We have tried our best to eliminate all mistakes and misrepresentation of facts but since its natural for humans to make mistakes, so we ask your pardon in advance for any such mistake.
Major topics covered in this report about Building Services and HVAC are:
Lifts/Elevators (functioning, components, selection criteria, manufacturers, study of Emmar tower elevator system).
Fuel Storage Tanks (purposes, international standards for fuel storage tank design, use of EN-12285-1 , EN-12285-2 DIN 6612, Designing of a 10,000 Liter fuel storage tank).
Fire Suppression Systems (Fire ingredients, fire classes, fire fighting techniques, fire suppression using clean gas technology and water sprinkler system)
Welding Techniques (Preparation of workpiece, preheating of electrodes and workpiece, appropriate welding technique depending upon requirement).
Heating Ventilation and Air Conditioning (HVAC):
Goals of an HVAC system, Components of an HVAC system, Split Air Conditioner System, Packaged Air Conditioner System, Cooling Tower Technology, Chillers, Air Handling Units and Pumps (Positive displacement pumps and Kinetic Pumps).
