4 Ventilation System Packages Bard Wall-Mounts are designed to provide optional ventilation packages to meet all of your ventilation and indoor air quality requirements. ll units are equipped with a barometric fresh air damper as the standard ventilation package. ll ventilation packages can be built-in at the factory, or field-installed at a later date. BROMETRIC FRESH IR DMPER - BFD STNDRD The barometric fresh air damper is a standard feature on all models. It is installed on the inside of the service door and allows outside ventilation air, up to 5% of the total airflow rating of the unit, to be introduced through the air inlet openings and to be mixed with the conditioned air. The damper opens during blower operation and closes when the blower is off. djustable blade stops allow different amounts of outside air to be introduced into the building and can be easily locked closed if required. Barometric Fresh ir Damper Motorized Fresh ir Damper Commercial Room Ventilator Economizer Energy Recovery Ventilator Form No. S349- Supersedes S349-7 Page 4 of BLNK OFF PLTE - BOP blank off plate is installed on the inside of the service door. It covers the air inlet openings, which restricts any outside air from entering the unit. The blank off plate should be utilized in applications where outside air is not required to be mixed with the conditioned air. MOTORIZED FRESH IR DMPER - MFD The motorized fresh air damper is internally mounted behind the service door and allows outside ventilation air, up to 5% of the total airflow rating of the unit, to be introduced through the air inlet openings and to be mixed with the conditioned air. The two position damper can be fully opened or closed. The damper blade is powered open by a 4VC motor with spring return on power loss. The damper can be controlled by indoor blower operation or can be field connected to be managed based on building occupancy. NOTE: The above vent systems are intake only without built-in exhaust capability. Building will likely require separate field installed barometric relief or mechanical exhaust elsewhere within the conditioned space. Balancing dampers in the return air grille may be required to achieve specified amount of outdoor air intake. COMMERCIL ROOM VENTILTOR - CRV The built-in commercial room ventilator is internally mounted behind the service door and allows outside ventilation air, up to 5% of the total airflow rating of the unit, to be introduced through the air inlet openings. It includes a built-in exhaust air damper. The commercial room ventilator (CRV) is a simple and innovative approach to improving the indoor air quality by providing fresh air intake and exhaust capability through the CRV. The damper can be easily adjusted to control the amount of fresh air supplied into the building. The CRV can be controlled by indoor blower operation or field controlled based on room occupancy. Two versions are available: the CRVS is power open - spring return on power loss; the CRVP is power open and power return. Complies with NSI/SHRE Standard. Ventilation for cceptable Indoor ir Quality. ECONOMIZER - ECONWM-Series The built-in economizer system is internally mounted behind the service door and allows outdoor air to be introduced through the air inlet openings. The amount of outdoor air varies in response to the system controls and settings defined by the end user. It includes a built-in exhaust air damper. The economizer is designed to provide free cooling when outside air conditions are cool and dry enough to satisfy cooling requirements without running the compressor. This in turn provides lower operating costs, while extending the life of the compressor. ECONWMT Equipment Building versions have extended air intake hood to deliver up to % of cooling rated airflow. " for ECONWMT-E or T, and E3 or T3 " for ECONWMT-E5 or T5 ECONWMS Classroom versions have 3" air intake hood to deliver up to % of cooling rated airflow. Standard Features: Fully modulating Honeywell Direct Drive Hi-Torque ctuator No linkage required Simple single blade design Positive shut-off with non-stick gaskets Electronic DB and/or Enthalpy sensors depending upon version Honeywell JDE electronic economizer module with precision settings and diagnostics DB or Enthalpy economizer versions available WLL-MOUNT ENERGY RECOVERY VENTILTOR - ERVF The wall-mount energy recovery ventilator is a highly innovative approach to meeting indoor air quality ventilation requirements as established by NSI/SHRE Standard.. The ERVF allows from to 45 CFM (depending upon model) of fresh air and exhaust through the unit while maintaining superior indoor comfort and humidity levels. In most cases, this can be accomplished without increasing equipment sizing or operating costs. Heat transfer efficiency is up to 7% during summer and % during winter conditions. The ERVF consists of a unique rotary energy recovery cassette that provides effective sensible and latent heat transfer capabilities during summer and winter conditions. Various control schemes are addressed - including limiting ventilation during building occupancy only. The ERVF is designed to be internally mounted behind the service door in the W7 or W7L model wall mount units. It can be built-in at the factory or field installed as an option. ERVF-*5C can be independently adjusted for intake and exhaust rates.
