MCDM AG.COM | NOV EMBER / DECEMBER 2017 | Medical Construction & Design 39 with a general exhaust clean airstream coming from rest- rooms and workrooms in the building. This allows for the recovery of energy that other- wise would have been wasted. This pretreated air then passes through a Type III desiccant wheel, which continuously transfers moisture from one side of the wheel to the other, leaving the discharge air at a low 40 grains of moisture per pound of dry air. A fi nal cooling coil maintains the discharge air temperature between 52 F and 65 F to temper heat gain from the desiccant. The higher discharge air temperature provides substan- tial energy savings on chilled water usage at the AHU and on re-heat energy usage at the VAV terminals. The lower air- moisture content allows the air to be tempered with a re-cool- ing coil to meet sensible space loads without risk of moisture condensation at the terminal box, eliminating the need for a fi nal fi lter. This approach enabled the cost-eff ective delivery of 100 percent outside air to each pa- tient room without the higher maintenance or fi rst cost of other systems like chilled beam or displacement ventilation.

It implements innovative solutions to support the highest standard of care, reduce energy use and cost and ensure sustainability.
