ENERGY SAVINGS USING RECIRCULATING AIR STERILIZATION Q. What is the electrical cost to run the NQI air treatment system if I install it in a room? (Exclusive of the replacement cost of the filters and lamps). A. The direct cost of the electricity to run the unit will vary depending on your cost of electricity. As an example let us use 10 ¢ per kilowatt-hour (KwH) with the unit running 24 hours per day. The formula for direct electric cost is : (WATTS
of UNIT/1000) x area electric rate x hours per day x days per year. For our example, using a NQ500 for 365 days per year, 24 hours per day at 10 ¢ KwH. (403 WATTS/1000) x $0.1 x 24 x 365 = $353.00 per year. However, this is a small cost when compared to the cost of achieving the CDC requirement of 6 ACH with a 'single pass' method. A single pass system means that all the supply air for the room is exhausted to the outside putting a great strain on the existing HVAC system. The heating and cooling cost per year for 6 ACH in a typical isolation room in New York is approximately $800. In Miami, with a higher air conditioning cost, that figure is in excess of $1,200. The NET COST to you of operating the NQ500 is the total annual electrical operating cost - added to the cost of consumables - less the cost of a single pass system with 6 ACH. Installing the NQ500, will actually represent a net SAVINGS in operating costs of between $400 and $800 a year. It is nice to know that with the NQ Industries, Inc. Air Treatment System you are getting added protection and saving costs, at the same time. Copyright 1997 by NQ Industries, inc. |
