A Study on the Establishment of an Optimum Diffusion Angle for a Built-In Type Heat Pump at Classroom
Abstract
teacher s efficiency is an important factor. Recently, some schools installed an air conditioner in classroom,while most schools selected the built-in type air conditioner. However, the study on a valuation of thermalenvironment is not sufficient, especially in classroom. It is insufficient that the study is a valuation ofthermal environment which considered valuation about indoor thermal environment diffusion angle and airvolume. In this work, the change of thermal environment was investigated for five kinds of air diffusionangle(15∘, 30∘, 45∘, 60∘, 90∘) for ceiling type air conditioner. The vector and temperature distributions ofair in the room were calculated by a 3-dimensional numerical method. This study was also conducted tocalculate the Mean Age of Air and Predicted Mean Vote(PMV). This analysis showed that 30-45° is theoptimum angle of diffusion in cooling mode and in heating mode.
