Ventilation
Opening
a window does provide ventilation but wastes energy
so that in winter the building's heat and humidity is
lost and in summer cooled, air conditioned air is replaced
with warm air from outside. The results are undesirable
for the indoor climate and for energy efficiency as
the HVAC systems are forced to work overtime to compensate.
Coolstream Ventilation can design a ventilation system
to suit any need, from a small fan in the wall to large
ducted fresh air handling units that can be used in
conjunction with air conditioning systems to keep you
at the right temperature as well as keeping your environment
fresh.
Target ventilation systems provide a cooling effect
by directing tempered fresh air to areas that operatives
occupy frequently, providing temporary respite from
the uncomfortable surrounding areas.
Natural ventilation systems achieve ventilation by taking
advantage of the natural convection currents created
by air at different temperatures, and are widely used
for office building atria. Natural ventilation for commercial
and industrial applications is extremely limited, as
mechanical assistance is required to move the air through
the ducted system.
It is important that an extract ventilation system is
balanced by an input or make-up air system to maintain
the displaced extract air.
Innovative
Designs
The use of heat pumps and heat recovery ventilation
systems are providing us with more environmentally friendly
ways of controlling air temperature inside buildings.
It is vital to be innovative as well as using modern
technology, especially in new large buildings, office
blocks, shops and restaurants to provide the healthy
quality of air that is required.
Heat recovery enables a system to recover up to approximately
50% of the energy from the extract airstream of a ventilation
system. As environmental issues become increasingly
influential in the design of mechanical ventilation
systems, the inclusion of a heat recovery facility can
contribute to considerable energy savings and the reduction
of related carbon emissions.
The most common type of heat recovery used for ventilation
systems is the plate heat exchanger. Energy is transferred
from one air stream to another with no cross contamination.
In areas where the input and extract systems are remote
from each other, a run-around coil system can be used
to overcome practical installation issues.
Ventilation
System Features:
• Environmental conditions improved
• Oxygen levels are increased and CO2 levels are
reduced with the introduction of fresh air
• Airborne contaminants such as fumes, smoke,
odours and dusts are diluted or removed
• Make up air input to balance extract
• Can be targeted to provide temporary respite
