ESTIMATION METHOD OF HUMAN THERMAL SENSATION AND COMFORT IN LIVING ROOM USING METHOD BASED ON BERKELEY MODEL

Abstract

Several heat sources can be considered to improve the living environment in cold conditions such as winter in north area. For example, air conditioning using convection heat transfer, floor heating using conduction heat transfer, heaters using radiation heat transfer, and solar radiation from windows on sunny days can be assumed. While it is important to evaluate each heat source from a composite perspective based on its energy consumption and other factors, this report presents a process for understanding the impact of various heat sources on human comfort, which is one factor in the evaluation. In this report, a thermal fluid analysis based on the Lattice Boltzmann Method is used to reproduce airflow behavior (convection), and coupled with a heat transfer analysis (conduction, radiation, solar radiation), an unsteady thermal environment is reproduced. Then, by combining the Berkeley model-based human body heat transfer extension, a physiology-based-thermal-comfort-evaluation results for living-room environments is presented.
