Description
Summary:Two conventional fan-coil units were modified by replacing the fan motor with a small water turbine as the power source. The thermal performance and energy requirements of the modified units were measured in a controlled environment rig and compared with those of the conventional ones under the same inlet conditions and water flow rate. It was found that for the larger units, an increase in the sensible heat ratio and decrease in the outlet air temperature were observed as the water and airflow rates were increased. For the smaller unit, both the sensible heat ratio and air outlet temperature were simultaneously increased as the water and airflow rates increased. At the same inlet air and water conditions, the sensible heat ratio and outlet air temperature for the smaller size fan-coil units were lower than their counterparts of the larger units.
