Working principle of heat exchange station: The heat carrier (medium) of the primary network closed circulation system and the heat carrier (medium) of the secondary network closed circulation system conduct heat exchange when passing through the heat exchanger, so that the heat of the lower temperature medium can reach the required temperature. Under the action of circulating pump, the primary and the secondary network repeat circulation and work continuously to achieve heating, cooling, process temperature control and other purposes.
The heat exchange station consists of heat exchanger, circulating pump, make-up water pump, electric control cabinet, water tank, decontamination device, water treatment equipment, pressure relief device, pipeline device, water separator/collector, degassing device, instrument, etc.

Heat exchange station can achieve the following functions:
Automatic temperature control;
Automatic control of circulating water pump in secondary network;
Automatic control of water replenishment and constant pressure;
On-site display of temperature, pressure, flow, heat, liquid level, outdoor temperature;
Self-protection of heat exchange station (default phase, motor overload, blackout protection, water shortage in water tank, undervoltage and overvoltage protection of heating system).
