Heat Pump - Plant Room

with PICV control


The heat pumps are connected to the controller through the valve actuator which controls the flow through each heat pump using the PICV.

The controller measures the inlet and outlet temperature to maximize Delta T and regulates the variable speed pump to maintain the required pump pressure.

For optimal heat pump efficiency, the use of either cascade or unison control is recommended.
