The Scholar series of heat pumps and air conditioners are designed to provide quiet, efficient cooling, heating and ventilation for classrooms in a single package. The air source units are our new Scholar III and the Scholar QV. The Scholar III and the Scholar QV units are available as heat pumps or air conditioners. The GeoScholar water source units are available only as heat pumps. The units are installed inside the classroom against an exterior wall. The vertical configuration minimizes the floor space occupied by the HVAC unit. Individual classroom units mean superior comfort and energy savings. All Scholar units provide the flexibility of part-load cooling and heating and redundancy by design. When a central chiller/boiler system fails, an entire wing or school is affected. If a Scholar unit needs service, only one classroom is affected. When only a portion of the wing or school is being used, a large chiller/boiler system may have to operate the chiller at a reduced part load condition, the boiler for reheat and a large air handler. With Scholars, only the classroom or office being used is conditioned.

To meet fresh air requirements, a full range of ventilation options are available, including the Marvair GreenWheel® Energy Recovery Ventilator. All service and maintenance can be performed while the unit is in the classroom; sliding the unit away from the wall is not required. The Scholar units can be controlled by a wall mounted thermostat or interfaced with an energy management system.

Cost Savings
The Scholar heat pumps and air conditioners are economical to install and operate. When compared to central systems, the Scholar units can be up to 50% less to install. See the case study on the Atlantic City Schools on a comparison of Scholar QV heat pumps to water source heat pumps. Because of the operating efficiency, the Scholar units can provide energy savings over their entire lifetime of operation. See the case study on the Polk County Schools case study for a comparison of the operating costs of a central system and Scholar heat pumps in identical schools.

Energy Efficient
The Scholar III heat pumps feature EER's from 10.7 to 11.2 when tested to the Air Conditioning, Heating and Refrigeration standard 390. Scholar III units with a two stage compressor have Integrated Part Load Value's (IPLV) of up to 16.15.
The Scholar QV heat pumps have EER's up to 9.40.
The GeoScholar water source units have EER's up to 17.0 and COP's as high as 3.7.

Quiet Operation
Educators and designers are increasing realizing the importance of good acoustics in the classroom. The Scholar series are designed to provide an environment conducive to learning. The Scholar III units feature a sound level of 45 dBA in an unducted installation. With ducting, the sound can be reduced even lower levels.

Elegant School Facade
With the Scholar inside the classroom, only a louver is visible on the exterior of the school. And the louvers are available in a wide variety of styles, configurations and colors to complement the faade of any school. For a complete description of the of the Architectural Louvers, please refer to the Architectural Louver Brochure.

Heat pumps and Air conditioners in a variety of sizes
Both the Scholar III and Scholar QV air source units are available as heat pumps or air conditioners with cooling capacities of 2, 2.5, 3, 3.5, 4, and 5 tons. The GeoScholar water source units are only available as a heat pump with the same cooling capacities as the air source units. All units are tested to UL standards, listed by ETL and performance certified according to the applicable Air Conditioning and Refrigeration (ARI) standard.

Easy to install
For our air source units, the Scholar QV and the Scholar III, a single opening in the wall provides ingress and egress of the condenser air and intake and exhaust of the fresh air. For the GeoScholar water source unit, the opening is used for fresh air intake and exhaust. Installation does not require expensive structural changes. This unique design makes the units ideal for both new schools and when renovating existing classrooms.

Fresh air
To meet the requirements of ASHRAE 62, Marvair offers a number of ventilation options on all of the Scholar units. All ventilation options can provide up to 450 cfm of outside air (up to 40% of rated air flow).

GreenWheel® energy recovery ventilator (optional). Recovers both sensible and latent heat with efficiencies up to 75%.        Power vent with motorized damper        Motorized damper        Manual damper

GreenWheel ERV

Humidity Control
The requirement for up to 30 cfm of outside air for each student can create serious problems with humidity. The Scholar units have always provided humidity control with hot gas reheat and the GreenWheel ERV. The Scholar III advances humidity control with an optional two stage compressor and an electronically commutated indoor blower motor. The two stage compressor provides better total comfort, uses less energy and better humidity control. The electronically commutated motor optimizes moisture removal by automatically maintaining the desired air flow across the coil.

Programmable Logic Controller
This on board computer provides many of the control functions, performs extensive self- diagnosis to assess the operational status and indicate a fault when detected. The PLC can be programmed remotely or with a removable program storage device. LED indicator lights show operational status and provide assistance with diagnosis if troubleshooting is ever required.

Full Range of Options & Accessories
All Scholar heat pumps and air conditioners offer a choice of either electric resistance or hot water heat and a full range of accessories including grilles, base stands, display boards, thermostats, trim pieces, and plenums. Please see the web page and product data sheets for each of the Scholar units for a full description of the unit.
