Air distribution and microenvironment evaluation for partition-type fan-coil unit task air conditioning systems

By Jing Youyin and Zheng GuozhongNorth China Electric Power University, Baoding, Hebei Province, China  
Numerically simulates the microenvironment for typical office workspace with partition-type fan-coil unit (PFCU) task air conditioning system by a K-ε three-dimensional turbulent model. Analyses and studies the temperature and velocity distribution, the draught rating (DR) and the predicted percentage of dissatisfied (PPD) at three supply air velocities. The results show that the room temperature distribution appears zoning and air supplying efficiency is higher, which can achieve total energy conservation, and that the task air conditioning mode can provide better thermal comfort environment without draught rating when the air supply velocity is well designed.
