Chiller Plant Optimization

ปัญหา

Chillers, chilled and condenser water pumps and cooling towers run on fixed schedules with no measured cooling output, so nobody can tell how efficiently the plant performs or where to start optimising.

ภาพรวมโซลูชัน

MILESGO gateways collect data from chillers, chilled water pumps, condenser water pumps, cooling towers, BTU / heat meters, variable frequency drives (VFD), electricity meters over Modbus RTU / Modbus TCP / BACnet/IP / M-Bus, and deliver it to the BMS, the energy management system, WEB HMI panels as BACnet/IP / MQTT / OPC UA. Field equipment keeps its own protocol and control logic; integration is done by configuration and point mapping, not custom code.

Typical scope

  • chillers
  • chilled water pumps
  • condenser water pumps
  • cooling towers
  • BTU / heat meters
  • variable frequency drives (VFD)
  • electricity meters

Protocol path

Modbus RTU / Modbus TCP / BACnet/IP / M-Bus → BACnet/IP / MQTT / OPC UA

Implementation checklist for the project manager

  • Collect register maps and protocol documents from every equipment vendor early; a missing map is the most common delay.
  • Write the control sequence (start/stop order, interlocks, set-points, fallback on communication loss) and have it approved before programming.
  • Commission in read-only mode first; enable write / control points only after the client approves each one.
  • Record CT ratios, meter IDs and multipliers in the point table; wrong multipliers are the usual cause of billing errors.
  • M-Bus: check unit loads and cable length per segment; 2-wire M-Bus gateways need a 24 V DC supply.
  • Build and simulate the configuration off site (FAT) before installation to shorten time on site.
  • Configure NTP so trends, alarms and meter readings carry consistent timestamps.

Project deliverables

  • Signed point table and protocol mapping
  • Gateway configuration files and backups
  • IP address plan and network drawing
  • FAT and SAT test records
  • As-built documentation and operator training

สถาปัตยกรรมระบบ

Field layer: chillers, chilled water pumps, condenser water pumps, cooling towers, BTU / heat meters, variable frequency drives (VFD), electricity meters, connected over Modbus RTU / Modbus TCP / BACnet/IP / M-Bus. Edge and integration layer: MILESGO protocol gateways and edge controllers, mounted on DIN rail in existing panels, polling each device, time-stamping values and buffering them locally. Upper layer: the BMS, the energy management system, WEB HMI panels, which receives the data as BACnet/IP / MQTT / OPC UA. Remote access for maintenance runs over VPN rather than open internet ports.

ขั้นตอนการส่งมอบ

  1. 1

    Site survey and point list

    Inventory devices, protocols, register maps, panel space, power and network paths.

  2. 2

    Design and point table sign-off

    Map every point to the target protocol and system; agree it with the client and the upper-system contractor.

  3. 3

    Configuration and FAT

    Build the gateway configuration off site, simulate it and test against the signed point table.

  4. 4

    Installation and wiring

    Mount gateways on DIN rail, wire RS-485 / I/O / Ethernet, apply the IP plan.

  5. 5

    SAT and alarm tests

    Verify values against local readings, test every alarm and command end to end.

  6. 6

    Handover and support

    Hand over configuration backups, point table and as-built documents; train operators.
