EVALUATING TRANSIENT INDOOR AIR TEMPERATURE DISTRIBUTION WITH ACCESSIBILITY INDICES
The creating methods and control strategies of indoor temperature environment in air-conditioned room have a great influence on energy consumption of buildings,and creation of non-uniform thermal environment has potential in energy-saving.However,researchers havent revealed how various kinds of boundary conditions influence indoor temperature distribution.To reveal such kind of influence directly,a series of accessibility indices evaluating the transient characters of heat transmission and a correspondingly analytical expression on the transient indoor temperature distribution under steady flow field are developed.Then the application of the proposed expression is demonstrated by a numerical case study.The proposed accessibility indices and expression may take an important role in online control of non-uniform temperature parameters,and are equally meaningful for studying indoor heat transfer,principle of temperature distribution and creation method of non-uniform indoor environments.
