3 Efficient & Cost Effective Caice Fan Coil Units are designed and built for efficiency offering reduced total cost of ownership and full compliance with building regulations.

This lower energy consumption means less heat transferred into the airstream when the fan is running, and this helps to maximise the cooling performance of the fan coil unit as a whole.

On developments using large quantities of fan coil units, this energy saving may lead to significant savings in other areas, for example reducing the cooling capacity of chillers in order to minimise

4 3 Efficient & Cost Effective Caice Fan Coil Units are designed and built for efficiency offering reduced total cost of ownership and full compliance with building regulations. Our 300 series range features only Electronically Commutated (EC) fans. These fans are up to 70% more energy efficient at providing the same duty when compared to equivalent AC motor versions. This lower energy consumption means less heat transferred into the airstream when the fan is running, and this helps to maximise the cooling performance of the fan coil unit as a whole. Our EC fan coil units offer a typical energy saving of 60W per fan. On developments using large quantities of fan coil units, this energy saving may lead to significant savings in other areas, for example reducing the cooling capacity of chillers in order to minimise capital expenditure and running costs.. Compliance All of the efficiency characteristics of Caice s fan coil units support compliance with the SFP limits in the 2013 revision of Building Regulations Approved Document L. Our 300 series fan coil units offer SFPs in the range of 0.20 to 0.40 W/l/s. EC fan motors can deliver typical energy savings of 60 Watts per fan, compared to equivalent AC motors

4 Typical Performance The five units in the Caice fan coil unit range have been developed to provide effective thermal performance even at low noise levels.

5 4 Typical Performance The five units in the Caice fan coil unit range have been developed to provide effective thermal performance even at low noise levels. Based on typical design temperatures for cooling (air on/off 23/12 C, chilled water flow/return 6/12 C), and with a guide noise level of NR35, the following sensible cooling duties can be achieved. Variable Air Volume When used in conjunction with a Building Management System (BMS) our fan coil units fully support Variable Air Volume (VAV) operation leading to further efficiency gains. Operating in this mode & triggered by sensors connected to a BMS, the fan coil unit s motor speed can be adjusted using a 0 to 10V DC signal. Fan Coil Unit Size Size 1 Size 2 Size 3 Size 4 Size 5 Sensible Cooling Duty 1.71 kw 3.00 kw 3.91 kw 5.24 kw 6.35 kw Responding to environmental conditions means that under normal requirements the fan motors can often be run below full design duty. This is particularly beneficial when a space is unoccupied, allowing a substantial reduction in speed leading to significant energy savings along with reduced noise levels. Equally fan speed can be increased to provide additional heating or cooling for higher duty requirements when the space is occupied. We are also able to offer our units with an integrated low cost controls package, enabling standalone and BACnet operation.
