Comfort and Energy Performance of a Low-power Task-ambient Conditioning System
The local comfort of feet,hands,and head determines the bodys overall thermal comfort (Zhang 2003,Arens et al.2006). We took advantage of this to design a task-ambient conditioning (TAC) system that heats only the feet and hands,and cools only the hands and face,to provide comfort in a wide range of ambient environments. The system was designed to be as simple,practical,and energy efficient as possible.Tests with human subjects show that the TAC system maintains acceptable comfort over a range of 18 30℃ in the ambient conditions. Per workstation,the TAC system uses a maximum of 41W for cooling and 59W for heating. By reducing the amount of control normally needed for the ambient environment in a building,energy savings of up to 60% in summer and 30% in winter are projected.
