The intelligent heating heat exchange control system adopts Siemens frequency converters and S7 series PLC as the core processing units. The touchscreen human-machine interface dynamically displays the working status of each device, data display, parameter settings, real-time curves, historical curves, fault alarms, report printing, etc. It resolves automatic temperature regulation, automatic constant pressure water replenishment, power-off self-protection, power restoration auto-start, and unattended automated operation.
System Functions:
1. Automatic switching between power frequency and variable frequency.
The system collects temperature and pressure signals to control the frequency conversion of circulation pumps and water replenishment pumps. It automatically enables variable frequency switching for multiple circulation pumps and multiple water replenishment pumps, with automatic switching between variable frequency and power frequency.
2. Simple, intuitive, and user-friendly human-machine interface for convenient operation.
Equipped with a touchscreen, the system features an excellent human-machine interface that displays the complete system operating status, current equipment conditions, and various thermal parameters. Operating parameters are centrally displayed digitally. It allows for local control and can also connect with the central control room, enabling users to monitor remotely.
3. Powerful remote communication capabilities.
It can connect to the host computer via wired or wireless means, enabling both LAN control and wireless monitoring. In the event of a fault, it immediately sends a wireless alarm signal to the administrator's mobile phone, allowing for prompt system maintenance.
4. Practical dual-function capability for both heating and cooling.
This intelligent heat exchange unit can provide both heating and cooling. By sharing core plate heat exchangers and components, it significantly improves the utilization rate of core parts, eliminating the 50% idle rate of core components in single-function units. This allows users to invest in one unit and effectively possess both heating and cooling heat exchange systems.
5. Highly automated settings for true unattended operation.
The automatic control system of this intelligent heat exchange unit uses components from Siemens, Schneider, or Chint, combined with advanced automatic control design. It features a high degree of automation, strong sensitivity, accurate temperature control, minimal fluctuations, and significantly saves on human resources.
6. Reliable and stable system protection settings.
The heat exchange unit system includes multiple system protections, such as over-temperature protection, over-current protection, power-off protection, and other safety measures to ensure safe and stable system operation and usage.
