US base invests in heat pumps as part of eco-efficiency drive

LATEST NEWS

Aermec has supplied ground source heat pumps for the Webster Navy Air Force Base in the United States, as part of a retrofit project designed to significantly reduce energy consumption.

Southwest of the Naval Air Station Patuxent River in Maryland, the 1000- Acre Webster Outlying Field Annexe is home to the Naval Air Warfare Center Aircraft Division (NAWCAD) 4.5 and NAWCAD 5.1.11, Coast Guard Station St. Inigoes, and a component of the Maryland Army National Guard.

Southwest of the Naval Air Station Patuxent River in Maryland, the 1000- Acre Webster Outlying Field Annexe is home to the Naval Air Warfare Center Aircraft Division (NAWCAD) 4.5 and NAWCAD 5.1.11, Coast Guard Station St. Inigoes, and a component of the Maryland Army National Guard.

When the U.S. Navy awarded a federal ESPC (Energy Saving Performance Project) at the Webster Outlying Field Annexe – a secure research facility and active airfield the remit called for the upgrade of 72 buildings and the implementation of major energy conservation measures.

US-based CEG Solutions installed new control systems and Ground Source Heat Pumps (GSHP) which were specified to replace existing oil-fired boilers and air source chillers in five of the largest buildings at the base along with upgrades to interior and exterior lighting, building controls, domestic water fixtures, and building envelopes.

Energy Savings

The ground breaking project is expected to reduce energy consumption in the Webster Outlying Field retrofit buildings by 38% and generate over $875,000 USD of annual utility and maintenance savings in the first year of performance. These energy savings will help the Navy achieve its goal or reducing total energy consumption and providing improved energy security. The project will also reduce carbon dioxide emissions by over five million pounds per annum, largely through the elimination of fuel oil at the base. This is equivalent to the average annual emissions of 536 passenger vehicles or 232 homes.

After reviewing the performance of competitor products, Aermec’s NXP simultaneous water source units could significantly reduce energy usage and provide impressive savings in the short term as well as long term performances.

The upgrades were carried out in a phased approach and included five buildings, three new geothermal field installations-vertical bore holes with over 24,000 feet of pipe in the ground along with five Aermec NXP units totaling 400 tons

To satisfy the buildings loads, the NXP machines were sized to handle all the heating they will ever need. The NXP machines limits in cooling were augmented by Aermec water to water NXW units to handle peak cooling loads when the NXP machines cannot carry the entire load.

The NXP simultaneous water source units operate on R410a and are designed for two or four-pipe systems and feature high efficiency scroll compressors with low power inputs. The NXW, is a high efficiency water cooled units, suitable for geothermal applications, featuring hermetic scroll compressors and delivering high efficiency levels at full and partial loads. Various configurations are available with one or two pumps on both the evaporator and condenser side. Both the NXW and NXP are Eurovent certified and designed to maximise energy efficiencies.
