Plate Heat Exchanger

with PICV control

Function

The primary function of the PICV is to control the water inlet temperature on the secondary side.

To secure the water outlet temperature on the primary side a sensor is placed here.

The balance and the full modulating control on the primary side is made by the PICV with a modulating actuator.

When the controller calls for higher or lower temperature on the water inlet on the secondary side, the PICV valve opens or closes to allow heating or cooling water from the primary side to enter the plate heat exchanger.

The temperature on the secondary side then changes to the desired temperature.
