Main HBC Controller

Plate heat exchangers

This is the component where the refrigerant gas is able to yield/absorb heat from the water line.

Two plate heat exchangers are installed, located at the ends of the HBC.

Both can produce hot water during heating mode and cold water during cooling mode.

During “simultaneous mode” one of the heat exchangers produces hot water while the other one cold water.


Both plate heat exchangers are equipped with inverter DC pumps.

The pumps allow circulation of water between HBC and the indoor units. The flow rate is controlled by a valves block.

Valves Block

A set of valves is connected to supply and return pipes of each indoor unit.

This valves block has two tasks: firstly it selects the hot or cold water header and then it regulates the flow fed to the indoor units based on the thermal power required.
