Cold-Climate Demonstration of Natural Gas Engine Driven Heat Pump and Electric Cold-Climate Heat Pump VRF Systems at Naval Station Great Lakes
Abstract
Variable refrigerant flow (VRF) heat pump systems are increasingly used in small commercial buildings in the U.S. as a high-efficiency heating and cooling option for multi-zone applications. However, the customized design and complexity of VRF configurations make it difficult to monitor and predict energy savings relative to baseline HVAC systems. Predicted energy savings are often based on energy modeling or data from controlled laboratory testing due to limited field data available for VRF systems, especially in colder climates. This ESTCP demonstration offered a unique opportunity to directly compare measured performance data for two VRF heat pump technologies to the baseline variable-air-volume (VAV) system and determine the potential energy and economic benefits for DoD facilities.
