Final Performance Report: Dual Fuel RTU Monitoring

This report summarizes the performance of the 15-ton Daikin Rebel dual fuel heat pump rooftop units (RTUs) RTU2F and RTU3F serving the back zones of 47-01 Queens Blvd, Sunnyside, NY 11104 from October 19, 2023, to July 31, 2024. The performance of these heat pump RTUs was characterized in terms of operating modes, delivered sensible capacity, efficiency, energy inputs, and emissions. The information needed to calculate these characteristics was derived from high-resolution operating data transmitted by independent data loggers, configuration data from the unit controllers, and public weather databases.
