DILUTION VENTILATION FOR INDOOR AIR QUALITY

• In 1989 the American Society of Heating,
  Refrigeration and Air Conditioning Engineers
  (ASHRAE) developed and adopted ASHRAE 62-1989,
  Ventilation for Acceptable Indoor Air Quality.
• Refer to section 8.2 in the text book to learn
  various considerations ASHRAE considered to
  establish the standards.

HVAC COMPONENTS AND SYSTEM TYPES

• While considering the ventilation aspects of HVAC
  systems, the type of system and its component
  should be reviewed in order to assess the
  potential sources of complaints regarding indoor
  air quality.
• For detailed description of the various
  components refer to section 8.3.1 in the text
  book.
