Characteristics of the Thermal Environment

Abstract : This chapter concerns how the environment impacts on humans in terms of the environmental components of the net energy balance: radiation, conductance, convection and evaporation. The fundamental relationship between each of these environmental factors and the exchange of energy between man and his environment is presented in detail in the first section. The second section describes the instrumentation required to quantify the environmental parameters: temperature, wind, radiation and pressure. These determine the rates of energy exchange. Section three discusses methods for assessing the total impact of the separate environmental components as a single, net effect. Keywords: Environment, Radiation, Convection, Evaporation, Energy balance, Human, Environment, Instrumentation.
