Project Info COMPLETE Project Title ET15SCE1250 - Laboratory and Field Evaluation of RTU Optimization Package Project Number ET15SCE1250 Investor Owned Utilities SCE End-use HVAC Sector Commercial Project Year(s) 2016 - 2019
Laboratory test a combination pre-cooler and fan/compressor speed controller provided by a major manufacturer installed with WCEC control algorithms. Use laboratory-test data to refine algorithms and optimize controls as needed. Field test the Roof Top Unit optimization package using one RTU at a field test site.
Project Results
This report describes a laboratory and field evaluation of a retrofit package to optimize the performance and efficiency of packaged air conditioning and heating Roof Top Units (RTUs). The package included Variable-Frequency Drive(s) (VFDs) to reduce the speed of the compressor(s) to 48 Hertz (Hz), and a condenser-air pre-cooler. This retrofit package is being considered as a method to save energy associated with air conditioning at all conditions, reduce peak electricity demand, and permanently reduce load on the compressor.
