| As a result, the panels were heating the air when the chillers were cooling it, and they remained on all night. |
| The hybrid plant combines two 1,000-ton gas-powered chillers with two comparable electric chillers. |
| The waste heat then drives the school's absorption chillers to cool buildings in the summer. |
| Rounding out this system are six ice water chillers and 15 evaporative condensers. |
| The university was able to upgrade all of its chillers to high-efficiency units and install variable speed pumping units. |
| These new greener chillers use sound waves for cooling instead of environment-damaging chemical refrigerants linked to global warming. |
