    Editor’s Notebook: Tech Update Commercial Unitary and Residential Indoor Air Quality Products

    Jan. 10, 2013
    Commercial Unitary Products include chillers, variable refrigerant flow units, and applied equipment. Residential Indoor Air Quality includes humidifiers, dehumidifiers, energy recovery ventilators, heat recovery ventilators, ultra-violet lights, filters, filtration systems, duct cleaning equipment, instruments, and testers.



    LL Series chillers and outdoor mechanical rooms are available from 50-365 tons with VFD controlled variable speed scroll compressors that allow the chiller to maintain the leaving water temperature set point at all operating conditions. During part load operation, reducing compressor capacity saves system operating costs. aaon.com


    Daikin McQuay
    Daikin McQuay introduces a new energy recovery wheel option for the Rebel rooftop unit.
    The energy recovery wheel option recovers approximately 75% of energy from the exhaust air stream. As the wheel rotates, outside air is drawn across one-half of the wheel while exhaust air is drawn across the other half, transferring sensible and latent energy between the ventilation and exhaust air streams.  daikinmcquay.com
