Dilution is the Solution – Increasing outdoor ventilation is essential for diluting and reducing the concentration of airborne pollutants in an indoor space. Dilution of contaminants by supplying clean outdoor air is an integral part of improving indoor air quality (IAQ) and maintaining the health and comfort of occupants. Proper temperature and humidity control of the inside space is also important for achieving optimal IAQ. To maintain a healthy indoor environment, air flow should not be stagnant since contaminants will move slowly and possibly stay within the indoor atmosphere. An energy recovery ventilation (ERV) system is a reliable solution to provide a constant source of air movement to dilute and exhaust contaminated air while bringing in pre-conditioned, fresh air.
Without an ERV system in place, the demand for higher rates of air change and increasing outdoor ventilation may present excessive energy burden and cost on a building’s heating and cooling needs.
Cost-Efficient ERV Technology – ERV technology helps lower energy costs and assists with the need to meet or exceed outdoor air ventilation regulations for occupant health and comfort.
ERV’s are specifically designed to increase outdoor ventilation in a cost-effective manner. Airxchange energy recovery technology enables ERV systems to provide fresh outdoor air at 1/3 the cost of conventional systems. It efficiently preconditions fresh air with recycled energy to reduce outdoor air ventilation loads up to 80%. ERV technology recycles energy already expended to heat, cool, humidify or dehumidify the indoor space. Instead of exhausting the energy to the outdoors, it is temporarily captured on the surfaces of heat exchanger and then released to pre-heat, pre-cool, humidify or dehumidify the incoming air.
ERVs remove heat and moisture from the incoming airstream before it reaches the HVAC system or the building. The outdoor air load imposed on the air conditioning (A/C) system can be reduced to only 20% of what it would be without the energy recovery ventilation component. Energy recovery provides energy saving benefits without sacrificing indoor air quality.
