NAPERVILLE, IL � September 2, 2003 � Ondeo Nalco
Company announced today that it has developed new technology that can save
hotels thousands of dollars each year through improved water and energy
conservation, and extended equipment life. 3D TRASAR®, Ondeo
Nalco�s revolutionary diagnostic and control system, detects upset conditions
in hotel cooling systems and takes rapid, cost-saving corrective action.
�Ondeo Nalco has developed a system that predicts when water and energy wastage in air conditioning systems is likely to occur or when events will lead to complete failure of a hotel�s air conditioning system.� Dr. Rao, the Ph.D. scientist spearheading the new technology, explained. �Once inefficient use of water or energy is predicted, the system automatically takes corrective action to prevent the wastage, potentially saving a hotel thousands of dollars each year.� Typically, a full-service hotel with more than 200 rooms has a centralized air conditioning system. At the heart of most centralized hotel air conditioning systems is an electrically-driven chiller. A chiller is essentially a large refrigerator. Chillers are expensive machines to run due to their high demand for electrical power. At an average of $0.05/kWh for electricity, it costs $45,000 - $55,000 per year to operate a chiller in a medium size hotel in warm climate locations. Larger hotels generally operate multiple chillers simultaneously and can consume well in excess of $100,000 per year in electricity. In areas with high average electricity rates annual electricity expenses for chiller operations can exceed $200,000 for a 1,000 room full-service hotel. In poorly maintained systems it is not uncommon for
a chiller to appear to be operating normally, though it may be operating
20%-30% inefficiently. In other words, an inefficient chiller will
still perform its intended function � it will just cost more money to do
it. For instance, if the chillers in that 1,000 room full-service
hotel were just 25% inefficient, it would cost an extra $50,000 per year
to provide the same amount of air conditioning for the same number of guests.
Well-maintained cooling systems generally operate within their acceptable control range more than 80% of the time. However, costly operational problems often occur during the 20% of time when a system is not under proper control. The 3D TRASAR technology detects upset conditions and takes appropriate corrective action. It also reports these events back to system operators, alerting them that further action may be necessary. Operating conditions that may lead to excess water and energy consumption, or deterioration of expensive cooling equipment are automatically detected and corrected by 3D TRASAR.
