Optimizing Chiller Efficiency Through Water Treatment
- Condenser of a water cooled chiller is prone to dirt and bacteria due to open circuit, necessitating good water treatment and monitoring.
- Lift in a chiller refers to pressure difference between condenser and evaporator refrigerant, affecting compressor workload.
- Chilled and condenser water temperatures, along with approach temperatures, determine required lift.
- Adjusting condenser water setpoint and chilled water setpoint can reduce compressor energy consumption.
- Approach temperature is the difference between chilled water supply temperature and refrigerant temperature in the evaporator.
- Setpoints in a chiller focus on chilled water supply temperature, controlled by temperature sensors and chiller controls.
- Chilled water pump and condenser water pumps distribute water in the building, with variable flow systems being energy-efficient.
