An AAON geothermal system may supply up to 140 tons of cooling capacity with only a single water connection. 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 geothermal systems.īy utilizing large commercial geothermal systems 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. By offering combinations of varying fan widths and diameters, the fans can be selected at optimum operating efficiency. AAON offers fan arrays configurable from one to four, direct drive, backward curved, plenum fans. AAON direct drive backward curved plenum fans offer improved efficiency, quieter operation, a smaller footprint and greater flexibility than comparable air moving devices in the HVAC industry. Direct Drive Backward Plenum FanĪ high efficiency geothermal system should be complimented by high efficiency air movement. By pairing variable capacity compressors with variable air volume fans, in a geothermal configuration energy efficiency is maximized and operating costs are drastically reduced. During much of the heating and cooling season, the compressor operates at a reduced energy level, saving you operating costs. The compressor continuously adjusts its capacity to precisely match the supply air temperature or leaving water temperature. Geothermal/Water-Source Heat Pump systems with variable capacity compressors improve occupant comfort and system efficiency by varying the capacity of the system to match the instantaneous heating and cooling load of the conditioned space. AAON rigid polyurethane foam cabinets reduce these monetary losses through improved thermal resistance, thermal breaks and quality air seals.

Heating and cooling energy lost through poor insulation and poor air seals results in significant monetary losses to building owners. This reduces the energy lost to the environment and increases the building owner’s savings. AAON double wall, rigid polyurethane foam cabinets save cooling and heating energy through improved insulation and air seals. Geothermal/Water-Source Heat Pump systems are premium products and should be constructed using a premium cabinet design. Rigid Polyurethane Foam Cabinet Construction Include AAON rigid polyurethane foam panel construction to save heating andĬooling dollars from escaping the HVAC cabinet, and AAON direct drive backwardĬurved plenum fans for efficient air movement. Equipment can be self-contained or split systems and Supermarkets and convenience stores, museums and libraries, churches andĪuditoriums, restaurants and many more applications desiring high efficiency, lowĬost heating and cooling. Opportunity to apply AAON heat pumps to educational facilities, office buildings, flow.The unique features and flexibility of AAON equipment provide you with the Continuous stable flow shall be less than our identified min. Min thermal flow shall not be less than below calculation.continuous thermal / stable flow rate for all pumps. The vendor shall state on the individual data sheet the min.Ten Ways to Prevent Low Flow Damage in Pumps: In general, a conservative approach is to supply pump systems with a system to prevent the pump from operating below its recommended minimum flow:
