| Natural-gas-fired absorption chillers and variable speed pumps, motors and fans increase the efficiency of the cooling and heating system. |
| The chillers cool water to 39 degrees and then the water is piped to customers' buildings for use in their air-conditioning systems. |
| The hybrid plant combines two 1,000-ton gas-powered chillers with two comparable electric chillers. |
| These new greener chillers use sound waves for cooling instead of environment-damaging chemical refrigerants linked to global warming. |
| As a result, the panels were heating the air when the chillers were cooling it, and they remained on all night. |
| Rounding out this system are six ice water chillers and 15 evaporative condensers. |
