The HBC includes any valves necessary to direct either cold or hot water to the various zones, along with refrigerant-to-water heat exchangers and variable-speed pumps for both the cold and hot water distribution headers. A sub-HBC is available to increase the number of zones served without the use of refrigerant.
A hydronic variable refrigerant flow system provides the following benefits compared to a conventional VRF system:
- No refrigerant piping in the occupied spaces
- Less overall refrigerant charge (30 percent less on average)
- Tighter temperature control
- Reduced defrost penalty
- Easier to install due to less copper piping
- Less noise, especially during defrost
