Buildings need a constant supply of fresh air to maintain a healthy indoor environment by avoiding the buildup of allergens, mould spores, dust mites and other chemical pollutants in the enclosed space. High levels of fresh air in the work place provides superior indoor air quality leading to greater employee productivity, fewer sick days and increased morale.
The dilemma for engineers is that higher levels of fresh air increase the load on the buildings heating and cooling system because the outdoor air temperature and humidity need to be conditioned to match that of the indoor environment. This additional fresh air load increases the size of the air conditioning plant and its energy consumption by up to 50%.
Air Change design and manufacture HVAC equipment specialising in systems that can pre-condition the fresh air supply to minimise the energy needed to condition (heat, cool and de-humidify) this outdoor air to the buildings specified operating conditions. Air Change technology allows greater levels of fresh air supply for higher indoor air quality with a significantly reduced energy consumption penalty.
This is achieved by our highly efficient, patented heat and energy recovery technology which can reduce the fresh air load imposed on the air conditioning plant by up to 75%. (See The Technology).
Reducing the peak fresh air load reduces the air conditioning plant size and its energy consumption saving money and reducing green house gas emissions. Air Change products have been well received because they supply conditioned fresh air in a simple, energy efficient, low maintenance, cost effective packaged unit.
We can engineer a tailored HVAC solution for any application because we have extensive engineering expertise in innovative heat recovery and ventilation systems.
