1 , � �� ,. ,.u�� p��e � ; �� GreenWheel� ERV exhaust air motor controlier— Aliows independent contral of the exhaust and intake biowers. When used, the standard speed controller operates the intake blower and the optional second controlier, the exhaust blower. Individual blower control allows positive pressurization.of the classroom. Fieid ar factory installed. �� . �� ` -: ��'� �� The Marvair�' GreenWheel� ERV is a total energy (both sensibie and latent) wheel that reduces both construction and operating cost while ventilating the classroom to ASHRAE 62-1999 requirements. The use of the GreenWheel ERV reduces the energy load of the outside air. Exhausting stale, inside air keeps indoor pollutants and harmful gases to a minimum..The Marvair GreenWheel ERV has been tested and certified according to ARI Standard 1060. How It Works - During the summer, cool dry air from:the classroam is exhausted through the GreenWheel ERV to the outside. As the air passes through the ratating wheel, the desiccant becomes cooler and drier. 5imultaneously, hot humid air is being pulled across the ratating wheel. The cool, dry desiccant absorbs moisture and heat from the incoming air. The cooler, drier air is mixed with the return air from the classroom and distributed throughout the room. In the winter, warm moist air is exhausted through the GreenWheei ERV to the outside. As the air passes through the rotating wheel, the desiccant becomes warmer and absorbs moisture. Simultaneously, cold dry air is being pulled across the rotating wheel, The cald, dry air absorbs heat and maisture from the desiccant. The warmed air is mixed with the return air from the dassroom and distributed througtiout the room. Quality Components -The GreenWheel ERV Ventilation package consists of the GreenWhee{ cassette, an incoming air blower, an exhaust air biawer, an air fiiter for the incoming air and ane fan speed controller that controls the speed of both blower motors simultaneously: As an aption, a second fan speed controller can be factory installed for independent control of the exhaust air motor and pasitive pressurization of the ciassroom. Also, an optional filter on the exhaust air is avaiiable on seiected models. Please consult yaur Marvair representative for details.The two blawers simultaneous(y pull fresh air from outside and exhaust air from the classroom through the rotating wheel. The air streams are separated by an insulated partition so that the incoming fresh air is not mixed with the exhaust air. Two variable speed blowers ensure that up ta 450 CFM of outside air can be brought into the room and the indoor air is properly exhausted. Variable speed blowers permit that the desired quantity of outside air is delivered into the room. Opti4nal independent exhaust air blower control allows positive pressurization of the classroom, i.e,, mare outside air can be introduced through the GreenWheel ERV than is exhausted.
