HVAC
HVAC is the acronym for Heating, Ventilation and
Air Conditioning.
Most people confuse HVAC with comfort when in fact
HVAC has very
little to do with comfort. Why?
Heating a space is easy and can be accomplished easily
and cheaply with a hot air furnace. But as many North Americans
experience, far too often we can be in a heated space and still
be uncomfortable.
Ventilation whilst important for indoor air quality is
not directly related to thermal comfort. Why? Because we can be
simultaneously comfortable and inhaling deadly carbon
monoxide fumes.
Air Conditioning is not 'cooling'. A/C is
conditioning the air which means it could be about humidity
control, air speed, filtration and temperature.
Our message is:
Heating a space does not make you comfortable nor does it control the quantity of moisture in the air. See Myth #9 in Radiant Mythology.
You can be comfortable in an environment with poor air
quality.
Conditioned air can be cool-dry and dirty or hot-moist and
clean...ideally it should be anything but the above.
When discussing HVAC with your builder or mechanical
contractor please understand the folks designing your interior
environment very rarely study the relationship between
architecture, mechanical systems and human physiology.
Unfortunately that's our North American system.
Fortunately good
information on indoor environmental quality is readily
available, is based on fact, is desireable, specifiable and
obtainable in your home or cottage - Click Here To Learn More. |
