Introduction
The chiller unit consumes a large portion of a building's energy. The following data will help in accessing the efficiency of the unit and provide a means to evaluate possible solutions.
Chiller Data
Chilling unit information required:
- Chiller Type <-
- Cooling Capacity (BTU/Hr)
- Operating Schedule <-
- Auxiliary Equipment (types, control, age)
- Typical Usage (seasonal, etc.) <-
- Chiller Controls (manual, automatic) <-
- Control Sensors (type and location) <-
- Pump Usage/Type (flow, pressure requirements)
- Sump Heaters
- Standard Chilled Water Temperature
- Heat Rejection Fans
- Minimum Condenser Temperature Limit
- Maintenance Schedule (level of fouling, cleaning)
- End-Use Devices (pressure requirements) <-
- Refrigerant Charge Limits
- Purge Units
- Valve Types
(Equipment and Operation Guide, Pumps, Compressors, Refrigerant)
Note: Cooling storage methods may provide a means to reduce electricity consumption by utilizing cheaper electricity rate periods.
