The advantages of a fan coil units (FCU) with fresh air system, compared to a full air system, are as follows:
- Flexible Control: FCUs allow individual control, enabling flexible adjustment of room temperatures based on usage patterns.
- Compact Size: FCUs have a smaller footprint and are suitable for installation even in existing buildings.
- Zone Control: Easy implementation of system zoning, allowing customization of heating and cooling loads based on room orientation, purpose, and usage time.
However, there are also disadvantages associated with FCU systems:
- Multiple Units and Maintenance: Due to decentralized placement, managing a larger number of FCUs can be labor-intensive.
- Indoor Air Quality: FCUs(fan coil units system) may provide poorer indoor air quality, making it challenging to achieve effective secondary filtration and prone to condensation-related issues.
- Fresh Air Volume Constraints: FCUs(fan coil units) face difficulties in providing sufficient fresh air due to their low static pressure and limited airflow distribution, making them practical for rooms with depths less than 6 meters.
Balancing these pros and cons requires thoughtful design, appropriate equipment selection, and proper installation. For designers, it’s about leveraging strengths and mitigating weaknesses. For consumers, it’s about choosing an air conditioning system that aligns with their needs.
