The SEMCO FV (Fresh Air Ventilator) Series of outdoor air pre-conditioners have been specifically designed to reduce the energy required to heat or cool outdoor air by up to 80 percent. The FV pre-conditioner allows the HVAC system to effectively and economically accommodate the three-to-four-fold increase in outdoor air quantities, which is recommended by the ASHRAE Standard 62, Ventilation for Acceptable Indoor Air Quality. This unique capability allows both new and existing buildings to benefit from a healthy indoor environment.
SEMCO's FV pre-conditioner significantly reduces the operating cost of a facility designed in accordance with the ASHRAE IAQ standard. It also improves humidity control when combined with unitary heating and cooling equipment. Because the SEMCO unit preconditions the incoming air to the packaged equipment, the required refrigeration capacity may be reduced by as much as 50 percent. Thus, the cost of the FV pre-conditioner and its installation is typically offset by the reduced size of the conventional HVAC system.
In existing facilities, retrofitting the HVAC system with an FV pre-conditioner allows the outdoor air quantity to be increased significantly without raising energy costs, losing humidity control, or changing the size of the current HVAC unit.
