Daikin Hi Wall Fan Coil Unit (FCU) – Chilled Water Air Conditioning Solution

What is a Daikin Hi Wall Fan Coil Unit (FCU)?

A Daikin Hi Wall Fan Coil Unit (FCU) is a wall-mounted chilled water air conditioning unit designed to provide efficient cooling and heating for residential and commercial spaces. Connected to a centralized chilled water system, the unit delivers uniform temperature control, quiet operation, and energy-efficient performance while maintaining the aesthetics of modern interiors.

Unlike conventional split air conditioners, Hi Wall FCUs operate using chilled water supplied from a central HVAC plant, making them ideal for hotels, hospitals, office buildings, and luxury residential developments.

How Does a Hi Wall FCU Work?

The Hi Wall FCU circulates room air through a chilled water coil where heat is removed during cooling operation. The conditioned air is then distributed evenly throughout the room using an advanced airflow system and automatic louvers.

For heating applications, hot water can be circulated through the coil, providing year-round thermal comfort.
