Benchmarking study of the refrigerated warehousing industry sector in California. PIER final project report.

Type of monograph: Report

Summary

A survey of refrigerated warehouses in California was conducted to determine the energy consumption patterns and energy saving practices. The survey included 67 public and 96 private warehouses. Total of 42 responses were received. Specific energy consumption (SEC) defined as kWh per year per cubic foot of storage volume was used as the measure of energy consumption. Typically the SEC decreased with increasing size (volume) of the warehouse This behavior was consistent with previously reported results from studies conducted in New Zealand, the Netherlands, United Kingdom and United States. The extent of use of eleven energy conservation technologies, namely, upgraded insulation, cool roofs, efficient lighting technology, aggressive evaporative condenser, thermosiphon oil cooling, computer control, compressor variable frequency drive (VFD), condenser VFD, evaporator VFD, floating head pressure, and sensor controlled doors varied from 22 to 74%. This indicates potential for improvement. A web-based benchmark tool was developed to assist operators to compare the energy use of their warehouse with a survey-based benchmark for improving energy efficiency.
