Choosing the right size of fan coil unit is crucial to ensure efficient cooling and heating. The size is determined by several factors, including the room area, ceiling height, insulation level, and local climate.
As a general guideline, for a standard room with average insulation and a ceiling height of 2.5-3 meters, you can calculate the required cooling capacity based on the room area:
·Rooms under 15 m²: 1.5-2 kW cooling capacity
·15-25 m²: 2-3 kW cooling capacity
·25-35 m²: 3-4 kW cooling capacity
However, other factors need to be considered. If the room has large windows facing south, poor insulation, or is located in a hot climate, you may need a larger unit. It is recommended to consult a professional HVAC technician to perform a heat load calculation, which will take all these factors into account and recommend the most suitable fan coil unit size for your specific needs.
