Experts in Building Environments™
Nortek Air Solutions offers both air handlers and packaged DX systems with energy recovery technologies. Our innovative Energy Recovery Systems integrate advanced technologies and components into the HVAC system design. These systems help capture the energy in the airstream that would otherwise be exhausted to the atmosphere and use it to either pre-heat or pre-cool the outdoor airstream, depending on the season.
This pre-heating or pre-cooling can lead to significant energy savings and a reduction in the building’s central plant size.
Energy Recovery Systems use the energy in building air that would normally be exhausted to treat the incoming ventilation air. During warmer seasons, the system pre-cools and dehumidifies the incoming ventilation air by sending the rejected heat into the exhaust airstream to cool the condenser coil at a lower temperature. During cooler seasons, the system uses the heat from the exhaust airstream to pre-heat and humidify the incoming ventilation air.
We offer several types of energy recovery technologies:
Heat pipe technologies. Heat pipes are air-to-air heat exchangers consisting of metal tubes charged with a refrigerant (R-134a for most commercial applications). Heat pipe technology offers one of the most robust solutions for difficult applications where high temperatures are encountered, low Exhaust Air Transfer Ratio (EATR) is required, or corrosive and contaminated air may be present with a high risk of fouling.
Our innovative energy recovery systems offer a number of benefits, including:
