The U. S. fresh Water Act demands the minimization of "adverse environmental impression" at cooling water consumption structures.  To facilitate an alternate of knowledge between all stakeholders within the factor, the electrical energy study Institute organised a countrywide symposium in 2001 to debate the which means of inauspicious environmental impression and strategies for its evaluation.

For example many chillers operate for three quarters of each cooling season at 60% or less of design capacity. A chiller's part load efficiency has a significant effect on operating costs. EFLH is defined as the annual ton-hours of cooling actually supplied divided by the supplying chiller's design capacity in tons. Using EFLH for analysis purposes is valid where the chiller plant has published continuous, performance values for energy input at all operating levels of output. Normally most centrifugal, screw, and absorption chillers fit this operating profile.

The differences between low and high efficiency cooling system alternatives shows up in the kW/ton for the chiller plus the heat rejection circuit. Therefore, use this total when comparing the kW/ton for chiller alternatives such as: 1. Air cooled versus water cooled 2. Low vs. high efficiency 3. Gas vs. electric driven (since gas equipment also has electrical requirements). Obviously, gas equipment also has fuel consumption which should be factored into the comparison. So far, we have compared equipment on the design day -- the relatively few hottest and/or most humid days in your area.

Electric, steam and fuel rate schedules, including demand and energy charges segregated by applicable seasonal or time-of-use criteria and appropriate fuel adjustment charges. 2. Chiller type, size and full load efficiency: for electric chillers consider the kW per ton; for natural gas fueled check the Btu per ton-hour, or the steam pressure at the unit for steam chillers. 3. Consider the size cooling tower required to reject the building's heat plus the work added to do the cooling that ends up in the chiller's condenser.
