CHILLER COOLING BEST PRACTICES ARTICLE:

Chiller load is the amount of cooling the chiller provides, while lift determines how hard the chiller must work to deliver the cooling. The greater the difference between evaporator and condenser pressures, the greater the lift and the more work the compressor must perform. By reducing the lift, more energy savings can be realized.
