FOUNDATION SYSTEM

Central Plant Control & Optimization

CONTROL OBJECTIVE

Coordinate chillers, boilers, pumps, towers and heat exchangers through load-led staging, pressure control, rotation and optimized start/stop.

Original concept visual of coordinated chillers, pumps and cooling towers in a central plant

WHAT THE SYSTEM MUST DO

Load decisions, rotation and optimized staging

  • Plant, boiler, pump and tower coordination
  • Load-based staging
  • Pressure, temperature and rotation control
  • Efficiency analysis and optimized start/stop
01

The operating problem

A central plant depends on chillers or boilers, pumps, towers, heat exchangers and valves acting together. Independent schedules can create poor staging and excessive pump or tower operation, while aggressive reduction can leave terminal demand unmet.

02

The objective

For central plant control, Kimma bases staging on building demand and available capacity. Pressure, temperature, rotation and fault-substitution rules coordinate the whole plant around current load, with clear operator override and fallback.

03

How the system works

  1. Schedules, terminal demand, supply/return conditions, differential pressure and equipment availability determine plant enable and the initial equipment combination.
  2. Load trends, temperature difference and pressure guide staging and variable-speed adjustment. Rotation considers runtime and maintenance state; faulted equipment exits through a defined substitution path.
  3. The platform records load, energy, temperatures, pressure, speed, starts and alarms so staging and optimized start/stop can be reviewed against real operation.
04

The practical outcome

The completed control strategy lets plant equipment operate as one system around actual demand. Operators can see why staging decisions occurred, intervene within defined authority and use trends to refine the sequence without compromising service.
