What is a Calorifier?
A calorifier is basically a heating fan with a coil and functions like a heat exchanger. In a calorifier, air is heated indirectly by circulating over the heating coil. Heat will merely be thermally transferred. The function of a calorifier is to retain thermal energy for later use and supplement primary heat source during peak hours. Calorifiers are commonly seen in hospital and factory application, where excess steam can be used to heat the water but calorifiers can also be used in commercial or even small domestic dwellings applications.
How is a Calorifier Application Optimized?
A calorifier, which is a static storage, will - with proper balance on the coil water - reduce flow to design flow and thereby save energy. FlowCon recommends three different solutions to a calorifier installation:
1. Calorifiers with Pressure Independent Control (PICV)
The PICV will react to system pressure changes and regulate the flow of water to required flow by adjusting the actuator position. This helps the system to be accurately controlled even with pressure changes and reduced loads.
FlowCon recommends the following PICVs:
2. Calorifiers with Temperature Control (TCV)
The TCV will react to system pressure changes and automatically provide the selected max. flow independent of pressure changes. In addition, the actuator will provide ON/OFF control, securing proper thermal performance always, even at partial loads.
FlowCon recommends the following TCV:
3. Calorifiers with Automatic Balancing (ABV)
The automatic balancing valve will react to system pressure changes and limit the flow of hot or cold water to required max. flow helping the system to be accurately controlled even with pressure changes. This solution may be installed with the separate control valve.
FlowCon recommends the following ABVs:
