American Services industrial HVAC repair and maintenance near Belleville knows that energy recovery ventilation is the energy recovery process of exchanging the energy contained in normally exhausted building air and using it to treat the incoming outdoor ventilation air in commercial HVAC systems. This process increases efficiency in commercial HVAC systems while reducing operating costs. During the summer months, the system will cool and dehumidify air entering the building with the “used” air leaving the building. Similarly, during the winter months, the HVAC system will warm and humidify the air using the same process.
The energy recovery ventilation process provides several key benefits. It allows the ability for an operation to meet the ventilation and energy standards set forth by the American Society of Heating, Refrigerating and Air-Conditioning Engineers, as well as improving the indoor air quality and reducing the HVAC equipment requirements and the loads placed upon the components within the commercial HVAC equipment.
This process is attained through the use of an energy recovery ventilator which is a type of air-to-air heat exchanger that transfers sensible and latent heat. The efficiency of this type of system is the ratio of energy transferred between the two air streams compared with the total energy transported through the heat exchanger. As with all manufacturers, specific efficiently ratings vary amount product, as well as location and application. Some systems have been shown to have heat exchange efficiencies as high as 70-80 percent, while others are as low as 50 percent. New technology is constantly being developed to increase efficiency ratings and each year new systems are introduced to the market. Check with your commercial HVAC specialist to see if your operation would benefit from an energy recovery ventilation system.
