| The university was able to upgrade all of its chillers to high-efficiency units and install variable speed pumping units. |
| Natural-gas-fired absorption chillers and variable speed pumps, motors and fans increase the efficiency of the cooling and heating system. |
| For example, some companies may reset chillers 4 degrees for a two-hour window and then bump it up a little. |
| These new greener chillers use sound waves for cooling instead of environment-damaging chemical refrigerants linked to global warming. |
| This building houses the boilers, chillers, tanks, and distribution equipment. |
| The waste heat then drives the school's absorption chillers to cool buildings in the summer. |
