EVALUATING INDOOR AIR TEMPERATURE DISTRIBUTION WITH NEW ACCESSIBILITY INDICES
The creatingmethods and control strategies of indoor temperature environment in air-conditioned room have a great influence on energy consumption of buildings,andcreation of non-uniform thermal environmenthas potential in energy-saving.However,researchers havent revealed how various kinds of boundary conditions influence indoortemperature distribution.To reveal such kind of influence directly,a series of accessibility indices evaluating the transient characters of heat transmission and acorrespondingly 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-uniformindoorenvironments.
