Application Scenario |
Recommended Allowance |
Considerations |
|
Residential Buildings |
20% |
Temperature fluctuations, occasional window opening |
|
Commercial Spaces |
30% |
High foot traffic, frequent door opening |
|
Special Requirements Areas |
40% |
High demand for constant temperature, no tolerance for fluctuations |
When selecting fan coil units, a 20%-30% capacity allowance is recommended to:
Handle extreme weather conditions
Accommodate usage variations (ventilation/occupancy)
Compensate for long-term system degradation
This approach ensures reliable performance, extends equipment lifespan, and maintains comfort despite higher initial investment.

|
Vertical Exposed fan coil unit |
Workshops, Warehouses |
Flexible installation, can be placed directly on the floor for use |
|
Cassette fan coil unit |
Bank Halls, Shopping Malls |
Four-way air supply, elegant and high-end, relatively expensive |
|
Wall-Mounted fan coil unit |
Villas, Shops |
Similar to household AC, can be connected to groundwater systems |
|
Floor-Standing fan coil unit |
Large Spaces |
Similar to household units, simple installation and use |
New homes: Horizontal concealed units blend with interiors.
Renovations: Wall-mounted or exposed units are easier to install.
Commercial spaces: Floor-standing or cassette units work best in large or design-focused areas.
Special needs: Low-noise units for quiet zones; anti-corrosion units for humid spaces.
Q: How do I know the size is right?
A: It should reach the set temperature quickly without long full-load runs.
Q: Can I mix brands?
A: Not recommended. Different parameters may lower system efficiency.
