Controller evaluation
One site. One system. One baseline.
Pick one refrigeration rack, CO2 system, ammonia plant or chiller. AReCoS measures its baseline, fits a model of that machine, checks the controller on the bench, and runs it on site only under a plan you approve. The pilot compares total energy at matched refrigeration duty and product temperatures, adjusted for weather and load. Any second site is decided from that result.
The three stages below are for refrigeration racks, CO2 systems and ammonia plants. A chiller follows its own four stages, starting with a read-only assessment and BAS setpoints that need no OEM. The chiller path
The Digital Twin, the machine’s physics model, runs on the controller. No cloud in the control path, and it keeps working with the internet down. How it works
Before stage 1
The scope, the paths and the status are on the controller page.
Three stages
Each stage ends in a written go or no-go.
- 1 · Engineering assessment, in software
- Offered now. AReCoS builds a model of your machine from its data and your test records, and replays what the controller would have done. No equipment is touched. You receive a system map, the baseline method, the model fit against your data, and the integration scope and cost for stages 2 and 3. Go: the model matches your data closely enough to judge.
- 2 · Bench check
- The controller hardware runs against the model of your machine in real time, hardware-in-the-loop, with the valves, drives and sensors your integration partner would fit on site. Fail-safe outputs and hand-back are tested here. Go: every agreed safeguard behaves as written.
- 3 · On site
- Baseline first, measured on the system as it runs today. Then the controller runs the commands agreed in scope, under a written commissioning, abort and rollback plan, for a period set in the agreement. You receive results against the baseline, by IPMVP Option B where the equipment is metered, and a written go or no-go before a second site.
Timing, data access, costs, installation duties and any share of savings are agreed in writing before each stage starts.
