Abstract
The disclosed technology includes a variable refrigerant flow (VRF) conditioning system including a single outdoor unit and a VRF path extending between the single outdoor unit and a plurality of terminals. The plurality of terminals can include a first terminal configured to condition air of an interior room and a second terminal configured to heat or cool a liquid. The VRF system can provide heating or cooling of air in different rooms or zones within a building or home while also providing heating or cooling of water. In response to a demand for heating or cooling at each terminal, the VRF system can vary the supply of refrigerant to each terminal, such that efficient and precise temperature regulation of air and liquid can be provided.
