www.trane.comHow will ventilation air be conditioned—energy recovery ventilator or dedicated outdoor air system? At a minimum, a fi lter and fan setup is required to supply ventilation air to a building. Many building energy codes also require exhaust-air energy recovery. As a result, a basic ventilation system might consist of an energy recovery ventilator

www.ashrae.org• Increase outdoor air ventilation (use caution in highly polluted areas); with a lower population in the building, this increases the effective dilution ventilation per person. • Disable demand-controlled ventilation (DCV). • Further open minimum outdoor air dampers, as high as 100%, thus eliminating recirculation (in the mild
Packaged Terminal Air Conditioners
f.hubspotusercontent40.netfresh air systems can be considerably downsized to service only the common areas of the property. This greatly reduces the cost and complexity of hotel design and construction. Unlike other PTACs, the FreshAire PTAC utilizes the main evaporator coil and Merv 8 filters to truly condition and filter the outside ventilation air.

ASHRAE Technical FAQ
www.ashrae.orgoutdoor air levels indicate an outdoor air ventilation rate of about 7.5 L/s/person (15 cfm/person). Laboratory and field studies have shown that this rate of ventilation will dilute odors from human bioeffluents to levels that will satisfy a substantial majority (about 80%) of unadapted persons (visitors) in a space.
