Integrated Approach

High Side + Low Side = Total Plant Optimization

ZedBee's CPO addresses both generation (high side) and distribution (low side) — because optimizing one without the other leaves savings on the table.

High Side — Generation

Chiller load balancing across multiple units for optimal loading
OEM curve integration for load-based chiller sequencing
Water-out temperature maintenance based on load demand
Cooling tower fan VFD modulation for approach optimization
Automatic condenser tube cleaning system (ATCS)

Low Side — Distribution

VAV installation at each zone to avoid overcooling
Delta-T and water balancing for AHU coil efficiency
IAQ-based demand ventilation using CO₂ differential
Automated AHU scheduling based on occupancy patterns
Weather synchronization for proactive load adjustment
Optimization Layers

Six Levers for Plant Efficiency

Each optimization layer compounds savings — from chiller sequencing to condenser cleaning.

Chiller Load Balancing

Distributes cooling load across chillers to keep each unit at its optimal efficiency point. Prevents one chiller running at 90% while another sits at 30%.

OEM Curve Sequencing

Integrates manufacturer performance curves to determine the most efficient combination of chillers for any given load. Stages units ON/OFF based on actual efficiency data.

Water Temperature Control

Maintains chilled water supply temperature based on actual demand rather than fixed setpoint. During low-load conditions, slightly raising supply temp saves compressor energy.

Delta-T Optimization

Water balancing algorithms across AHUs ensure designed Delta-T is maintained. Higher Delta-T = less water flow needed = lower pump energy = better chiller loading.

Condenser Approach

CT fan VFD + ATCS keeps condenser approach within design range. Every 1°C reduction in condenser water improves chiller COP by 2–3%.

Pump Optimization

VFD-controlled primary and secondary pumps matched to actual demand. Load-based staging with run-hour equalization for even wear and maximum efficiency.
