District heating substation



A district heating substation is a component in a district heating system that connects the main network to a building's own heating system.

Parts
The station normally has one or more of the following parts:


 * Heat exchanger - to split primary and secondary side of the system
 * Control valve - to regulate the flow through the heat exchanger
 * Heat meter - to measure energy consumption and allocate costs
 * Strainer - to remove particles that could block heat exchanger or control valve
 * Shutdown valve - to stop the flow on primary side in case of service or emergency
 * Differential pressure controller - to balance the network and improve working conditions of control valve
 * Temperature controller - to control temperature on secondary side by regulating the flow on primary side
 * Temperature sensor - to sense flow and return temperatures required for temperature control

Additional parts
In addition, a district heating substation may also include:


 * Pump
 * Manometer
 * Safety valve
 * Non-return valve
