A Seminar on HVAC System - PDF

What is the Purpose of HVAC ?
The main purposes of a Heating, Ventilation and Air-Conditioning (HVAC) system are to help maintain good indoor air quality (IAQ) through adequate ventilation with filtration and provide thermal comfort. HVAC systems are among the largest energy consumers in schools. The choice and design of the HVAC system can also affect many other high performance goals, including water consumption (water cooled air conditioning equipment) and acoustics.

The following actions detail how engineers can design a quality system that is cost-competitive with traditional ventilation designs, while successfully providing an appropriate quantity and quality of outdoor air, lower energy costs and easier maintenance.

  • Goal : To develop an automotive air conditioning system that is smaller and lighter than with conventional technology .
  • The challenge : The system must be capable of keeping a temperature of 22 degree centigrade inside a room, with an outside temperature of 40 degree centigrade. Also the system must be an efficient heating system , keeping an internal temperature of 15 degree centigrade with an outside temperature of 0 degree centigrade.

HVAC Components
  • Air Conditioners
  • AHU's
  • Dehumidifiers / Heater
  • Filters (Pre & HEPA)
  • Dust Extractore
  • Ducting (For delivery of controlled air)
  • Supply Fans
  • Smoke Detectors
  • Damper Humidity/Temp/Pressure sensor
  • Heating & Cooling Coils
