01
Focused chiller retrofit
Review sensor circuits and loading/unloading. Hui Energy materials describe a simulated-temperature-signal approach.
Solutions / Central chiller optimization
Maintain comfort. Match cooling to demand.
High cooling bills and inefficient part-load operation? Start with the controls and metering of existing chillers.

Define the scope before choosing equipment.
02
Whole-plant coordination
Assess chillers, pumps and towers together; measure electricity and cooling across the whole plant.
03
Comfort and operating limits
Prioritize comfort, cooling demand and existing protections; review disengagement, bypass and pilot acceptance.
Equipment and connections you can see.
Combine local management, sensing and control to suit the chillers and wiring.

Hui Energy uses a simulated temperature signal for control. RS485, LoRa or 4G carry telemetry; BMS interfaces require a separate review.Retain original controls and a bypass path
Check sensor wiring and manufacturer requirements; test fault disengagement and manual restoration before live operation.
Start with a pilot. Measure the outcome.

Questions before you choose.
Can every existing AC system be upgraded?
Review the chiller model, temperature sensors and controls first. VRF, split AC, district cooling and critical rooms require separate assessments.
How much can we save, and how is it verified?
Confirm against the site baseline and pilot results. Agree on boundaries, weather and load adjustments, comfort targets and anomalous-data rules in advance.
Can it work with our BMS?
Share equipment, point lists and available interfaces. Review metering, the chiller control circuit and BMS integration separately, subject to protocols and authorization.
Does this provide carbon certification?
The solution organizes operational energy and emissions data. Certification, trading, offsets and whole-life building assessments require the relevant frameworks and specialists.
