Chilled-water air-conditioning solutions for buildings and projects, from the cooling plant to the fan coil unit serving the occupied space.
The chiller and the FCU are not interchangeable. Each has a separate role in the cooling system.
The chiller serves the central chilled-water network. Its type and capacity are selected according to the cooling load and project design.
A fan coil unit uses chilled water through its coil and moves conditioned air into the occupied space.
A simplified view for understanding the system. Actual equipment and control configuration follow the project design.
Illustrative sequence only — final chilled-water flow, controls and equipment selection depend on the project.
It receives chilled water at the coil, moves air across the coil and serves the space according to the selected unit and control arrangement.
Selection starts from the cooling load and system design, then the equipment is matched to the project requirements and available manufacturer data.
For a new project, send the available drawings and requirements. For an existing system, send the system information and the operating issue before the service scope is confirmed.
Share the project use, drawings and current design information for scope review.
Share the unit schedule, drawing or existing unit information when available.
Diagnosis follows inspection and system data before a confirmed repair scope is stated.
You do not need to estimate tonnage or FCU capacity yourself.
The chiller produces chilled water for the HVAC system. An FCU uses chilled water through its coil to cool air inside a room or zone.
In a typical chilled-water fan coil system, the FCU is cooled by chilled water passing through its coil rather than by a direct refrigerant circuit at the room unit.
Selection is based on the project cooling load, system design and equipment requirements. Capacity is not fixed from a general room-size table.
Yes. For an existing system, the next step starts with the available system information and inspection before a confirmed diagnosis or repair scope is defined.
We identify the project scope first, then the technical selection or service path follows the actual system data.
