Air-cooled chillers

Chilled water with outdoor heat rejection.

An air-cooled chiller produces chilled water and rejects heat to outdoor air. Its location affects airflow, noise and maintenance access.

PLANNING / SELECTION / HANDOVER

Before choosing the equipment

Bring the current load profile and desired redundancy to the design team. Ask about ambient design conditions, placement, electrical supply and compatibility with existing pumps and controls.

What belongs in the quote

Include lifting, isolation, water-side work and startup in the scope. Request the design flow and temperatures, operating sequence and performance verification plan.

Think about the surrounding system

Bring operating hours, occupancy patterns, tenant constraints and existing equipment schedules to the first discussion. Agree who owns design, electrical work, structural review, roof penetrations, controls and commissioning. Plan shutdowns around the building rather than discovering access restrictions when replacement equipment arrives.

Three questions for your contractor

  1. What load and ambient conditions were used?
  2. How is redundancy handled?
  3. Which pump and control changes are included?

Prepare a useful first conversation

Bring the site location, building use, equipment model details and photographs of accessible equipment. Describe the problem or planned change and any access or shutdown constraints. Ask the contractor to identify design assumptions, excluded work, required approvals and who will commission the finished system.

This is a project-planning guide. Final equipment selection and installation details need a qualified contractor or designer familiar with the site.
