Superior FeaturesVariable CapaCity Compressor
Systems with variable capacity compressors improve comfort and efficiency in areas where heating and cooling loads are different by varying the capacity of the compressor to match the instantaneous heating or cooling required by the space. The compressor continuously adjusts its capacity to match the precise air temperature, or leaving water temperature, setpoint. During much of the season, the compressor operates at a reduced energy level, saving you valuable dollars. By combining the variable capacity compressor with a variable air volume fan system, efficiency is maximized and low operating costs are achieved. Variable capacity compressors also offer a great way to increase capacity.
DireCt-DriVe, baCkwarD CurVeD Fan A high efficiency geothermal refrigeration system should be complimented by high efficiency air movement. AAON direct drive, backward curved plenum fans offer improved efficiency, quieter operation, superior uptime, a smaller footprint and greater flexibility than comparable air moving devices in the HVAC industry. AAON offers fan arrays configurable from one to four, direct drive, backward curved, plenum fans. By offering combinations of varying fan widths and diameters, the fans can be selected at optimum operating efficiency. Direct drive, backward curved impellers require up to 15% less power than belt-driven, forward curved fans, at the same duty requirements, making them uniquely suited for high efficiency applications such as GSHP systems.
rigiD polyurethane Foam Cabinet ConstruCtionGeothermal units are premium products and should be constructed using a premium cabinet design. AAON double wall, rigid polyurethane foam cabinets save cooling and heating energy through improved insulation and air seals. This reduces the energy lost to the environment and increases the building owner’s savings! Saved energy is saved money. Heating and cooling energy lost through poor insulation and poor air seals results in significant monetary losses to building owners. AAON rigid polyurethane foam cabinets reduce these monetary losses through improved thermal resistance, thermal breaks and quality air seals.
AAON offers a complete line of geothermal (ground loop or ground source) products. Ground Source Heat Pump (GSHP) systems by AAON are among the most efficient, environmentally friendly ways to heat, cool and dehumidify buildings by recovering otherwise wasted energy and utilizing that energy to satisfy the needs of the building.
AAON geothermal and water-source heat pumps use the constant temperature of the earth as the exchange medium instead of the outside air temperature. A few feet below the earth's surface the ground remains at a relatively constant temperature. Depending on latitude, ground temperatures range from 45°F to 75°F. This ground temperature is warmer than the air above it during the winter and cooler than the air above it in the summer. The geothermal heat pump takes advantage of this constant temperature by exchanging heat with the earth through a ground heat exchanger.

Robust Applications Central geothermal units
By utilizing GSHP rooftop units to provide outside air to occupied spaces, or interior units, the total number of units in the building can be reduced and complexity of the water piping can be simplified. An AAON geothermal unit may supply up to 230 tons of cooling capacity with only a single water connection! The air from GSHP rooftop units can be ducted through conventional ductwork or the outside air can be used to supply smaller interior GSHP units that serve individual zones. Because AAON GSHP units have no outdoor fans, in addition to high efficiency, the units offer extremely quiet operation and have low maintenance requirements.
Dual FuelAll AAON high capacity GSHP rooftop units are available with backup and/or supplemental heating capability. As dual fuel units the GSHP may include an additional heat source from natural gas, propane, steam, hot water or electric heat. Dual fuel offers great flexibility by allowing a second heat source to be used as a supplemental heat to the heat pump or a form of back up heat if water loop down time is required.
sounD anD spaCe sensitiVe appliCationsAAON split system GSHP can be used in new or retrofit applications. In a retrofit application exterior air-cooled condensing units can be replaced with water-cooled condensing units and, in many applications, the existing refrigerant piping between the condensing unit and air handler can be reused. Because a water-cooled condenser uses no exterior fans, the unit sound is often not detectable by building occupants and neighbors. By utilizing a split system, noisy indoor compressors can be removed from occupied spaces in office buildings, hotels, health care facilities, banks, schools, condominiums, apartments and other sound sensitive locations. The refrigerant-to-water heat exchanger, along with the compressor, can be located in a mechanical room or on the exterior of the building
and only a quiet operating indoor fan and coil remain in the occupied space. This not only removes noise from the occupied space, it also removes compressor maintenance requirements from the occupied space and makes the interior unit smaller - saving valuable interior space.
water-to-water AAON water-to-water systems are highly efficient units which
can greatly reduce operational costs while at full load or part load conditions. Units may be selected with single or multiple circuits to provide redundancy and prevent unwanted downtime. AAON water-to-water systems provide conditioned water for radiant floor heating, domestic hot water, pool heating, as well as, snow and ice melting. AAON water-to-water heat pumps and chillers occupy less space than central station chillers and can be transported easily through doorways, elevators and hallways.

AAON Geothermal Quick Selection
Variable CapaCity sCroll CompressorsWith 10-100% capacity control these scroll compressors can match the load needed by the unit. The compressors vary the volume of refrigerant that flows through the cooling sys-tem allowing the unit to tightly control the air temperature and save energy when the unit is not running at full load.
Variable speeD supply FansECM (Electronically Commutated Motor) driven direct drive backward curved plenum supply fans are available on SB Series units to provide precise airflow control and reduced power consumption. Direct drive fans do not have belt energy losses and backward curved plenum fans are more energy efficient than housed forward curved fans.
water-sourCe anD geothermal heat pump ConFigurationAn SB Series water-source/geothermal heat pump unit can heat the air as energy efficient-ly as it cools it. By transferring heat from the earth to the building, the SB Series heat pump requires no fossil fuels.
Double wall rigiD polyurethane Foam injeCteD panel ConstruCtionAAON is setting a new standard for per-formance with double wall construction using closed cell polyurethane foam in-jected insulation. Not only does it have more than twice the insulating R-value, it provides increased sound dampening, and creates a far more rigid and stronger assembly with less air leakage than fiber-glass insulated construction.
