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
