(OP)
Our company presently uses 20 ton commercial HVAC units to "try" and moderate temperatures in a 500K facility in the deep south. These units are working constantly, consuming massive power, and only make a 5 degree cooler workplace. I am looking into possibly going to chiller type unit. Any suggestions or comments?





RE: Who makes dependable/efficient HVAC chillers?
The overall efficiency of the chiller system can be improved by (a) using a multistage chiller ( b) use of a working fluid better suited for the local ambient temperatures and rquired chilled water temperatures (c) improving the heat rejection system ( cooling towers) . If natural gas is available, one can (d) use the natural gas to fire a microturbine which powers the chiller compressors, and the turbine exhaust heat can operate an auxiliary absorption chiller. For item (d) the energy efficiency is on the order of 85% of the combined cycle, whereas the purchase of utility electircal power is on the order of 25% energy eficiency, including losses in transmission and generation.
