Business centres
A central system serving floors and tenants with variable loads.
Central cooling
Chiller–fan coil systems
Central cooling for facilities where scalability, flexible hydraulics, redundancy and energy control matter.
System architecture is determined by more than peak capacity. We consider part loads, zone schedules, temperature regimes, pumping energy, redundancy and serviceability.
Facilities
Suitable applications
The specific configuration depends on the architecture, operating modes, technical constraints and requirements for subsequent operation.
Retail and hotel complexes
Many zones, long operating hours and requirements for centralised control.
Manufacturing
Process cooling, redundancy, precise temperature control and year-round operation.
Tasks
What we address
We start with the outcome required by the owner and operations team, rather than a list of equipment.
Part-load efficiency
We select the number of units, system configuration and staging algorithm.
Stable hydraulics
We calculate flow rates, pressure differentials, balancing requirements and pump operation under variable conditions.
Managed risk
We incorporate redundancy for critical components, bypasses and failure scenarios.
Engineering approach
How we develop the technical solution
Each step reduces uncertainty and links design parameters to the building’s actual operation.
01Profile
We develop a load profile, not just a single peak value.
02System layout
We compare hydraulic arrangements, unit numbers and temperatures.
03Standby
We determine the consequences of failure and the resilience required.
04Algorithm
We define staging and controls to minimise costs.
Scope of works
What the work includes
We agree the scope before work begins, so the client understands the outcome, the boundaries of responsibility and how it will be verified.
Cooling plant
Chillers, dry coolers, cooling towers, heat exchangers and operating modes.
Hydraulic schematic
Circuits, pumps, buffer storage, headers, control and balancing.
Cooling consumers
Fan coil units, air handling units, process equipment and temperature schedules.
Water treatment
Heat transfer fluid quality, expansion, make-up, filtration and protection.
Automation
Staging, setpoints, weather-based control logic, energy monitoring and supervisory control.
Commissioning
Flushing, testing, balancing and verification of algorithms and operating modes.
Interconnections
Related solutions
HVAC works as a system. That is why we link equipment, controls, servicing and operating scenarios.
In practice
Relevant projects
Examples where the engineering approach has been tested through commissioning and subsequent operation.
