What is a cassette fan coil unit?
Cassette fan coil units, also known as ceiling-embedded fan coils, are water-based central air conditioning terminals. The unit body is concealed within the ceiling, with only a square panel visible and clipped onto the grid frame. Connected to chilled and hot water supplies for heating and cooling, each unit supports independent temperature control.

Q2: How many air outlet styles are available on the market? Which one is the mainstream?
There are three categories in total:Two-way, four-way, and eight-way air distribution
4-Way Airflow: Industry Standard, Market Leader
Standard models from major brands (Midea, Gree, Volker, etc.) feature four-way airflow. They account for over 70% of engineering and residential installations, offering lower costs, a slimmer profile, and maximum versatility.
Eight-way airflow: upgraded premium model, not a standard mainstream option.
Many manufacturers advertise 360° all-direction airflow by adding small side vents at the four corners for softer, even coverage with no dead zones. However, this design increases cost and requires specialized panel molds, so it is typically used in high-end commercial installations.
Dual-sided airflow: Niche designFor narrow shops and corridors only.
Q3: How do you tell the difference between a tetrahedron and an octahedron?
4-Way Airflow: Large air louvers only on the four long sides; no air outlets at the four corners.
Eight-way airflow: Four long sides plus four diagonal corners each feature independent mini air guide vanes, totaling 8 air delivery structures.
Q4: Are cassette fan coil units and ducted VRF indoor units the same thing?
No. The cartridge is...Water SystemRequires a dedicated chiller unit. Standard ceiling units are VRV systems with built-in compressors; the two systems cannot be mixed.
