Industrial Chillers for Air Conditioning & Data Centers by Friulair

In commercial, industrial, and tertiary buildings, indoor comfort directly impacts productivity and well‑being. The chiller stabilizes indoor temperatures, ensuring quiet, continuous operation and adapting to changing climate conditions and varying load profiles. Efficient systems support sustainability goals and contribute to energy certifications increasingly required by property managers and investors.

In data centers, thermal management is critical. Cooling infrastructure must maintain stable and precise temperatures, support dense and growing IT loads, and operate continuously without interruption. Even minor deviations from setpoints can degrade performance or cause server shutdowns. Friulair chillers integrate industrial‑grade components and advanced electronics to meet these stringent demands while supporting operational resilience.

Seasonal Efficiency (SEPR HT) & Part‑Load Performance

Since most annual operation occurs at partial load, SEPR HT is a critical metric. High‑efficiency scroll or screw compressors, microchannel condensers, EC fans, and advanced expansion valves enable Friulair chillers to maintain excellent efficiency in real‑world conditions—reducing energy consumption and lowering operating costs.

Supply Temperature & ΔT Optimization

Optimizing chilled‑water supply temperature and ΔT reduces compressor lift, minimizes pump consumption, and enhances overall system efficiency. This strategy improves temperature stability, reduces cycling, and extends component lifespan.

Data Center Free Cooling: When It Makes Sense

Free cooling leverages favorable ambient temperatures to decrease mechanical refrigeration. In temperate regions, free cooling can significantly reduce annual energy use while maintaining strict IT environmental thresholds. This approach supports ambitious energy‑efficiency targets and lowers operating expenses.

Correctly specifying an air conditioning chiller plant is essential to ensure efficiency, reliability, and long‑term operational stability.
A structured approach helps designers, consultants, and end users select the most suitable data center or HVAC chiller configuration, avoid oversizing or inefficiencies, and prevent operational risks throughout the system lifecycle.

Thermal Design Parameters

Supply / Return Temperatures, ΔT, Flow Rate & Glycol
Correctly defining chilled‑water temperatures, temperature difference (ΔT), and flow rate ensures accurate chiller sizing and stable operation.
Glycol concentration must be aligned with the minimum expected ambient temperature to guarantee freeze protection without compromising heat‑exchange efficiency.

Environmental Conditions & Protection

Ambient Envelope, Corrosion Protection & Coil Treatments
Installations in coastal, urban, or industrial environments may require specific condenser treatments and corrosion‑resistant materials.
Low‑ambient packages protect the chiller during cold climates and ensure reliable year‑round operation in both air conditioning and data center applications.

Hydraulic Configuration
Friulair offers integrated hydraulic solutions including:

• Single or twin pumps with different available head pressures
• Pressurized or atmospheric buffer tanks
• Correctly sized expansion vessels
• Anti‑freeze heaters for low‑temperature environments

Choosing the right hydraulic configuration increases system reliability, simplifies installation, and improves overall control stability.
