Dispersion pattern of carbon dioxide from human sources - afactor to consider in demand controlled ventilation systems.

Carbon dioxide from (simulated) people distributes fairly evenly in a closed office room, but can show an irregular height distribution when the door to a connecting space is open. The distribution and room to room transfer of carbon dioxide is evaluated in a 4-room test building and is discussed in terms of its implication for C02-controlled ventilation.

Monitoring of automatic diagnostic sensors for oil-fired heating equipment.

In 1989, Canada Mortgage and Housing Corporation entered into a joint venture initiative to field  est three diagnostic devices for  oil fired heating equipment. These devices include:

  • a Flame Quality Indicator
  • a net peak stack temperature sensor
  • an oxygen sensor

 

Occupancy sensors for ventilation control.
