Feasibility Study: Ductless Hydronic Distribution Systems with Fan Coil Delivery

Feasibility Study: Ductless Hydronic Distribution Systems with Fan Coil Delivery

Building Technologies and Science Center

Research output: NREL › Subcontract Report

Abstract

The primary objectives of this study are to estimate potential energy savings relative to conventional ducted air distribution, and to identify equipment requirements, costs, and barriers with a focus on ductless hydronic delivery systems that utilize water-to-air terminal units in each zone. Results indicate that annual heating and cooling energy use can be reduced by up to 27% assumingreplacement of the conventional 13 SEER heat pump and coil with a similarly rated air-to-water heat pump.
