彩色照片及影片類國家檔案之溫溼度環境控制技術

The Environmental Control Technologies for Preservation of Color Photographs and Films

本文首先藉著前人對檔案材料特質與壽命週期之研究成果，來說明環境控制條件對檔案保存之重要性，然後再根據美國冷凍空調學會（ASHRAE）出版之相關技術資料，以淺顯的空調原理、基本空調過程、以及系統設計分析，對於「彩色照片及影片類」國家檔案的低溫低溼庫房環境控制技術作一介紹。希望透過本文的說明，能夠讓大眾對於低溫低溼檔案庫房環境控制技術建立起初步的概念。

This article reviews literatures on the subject of relationship between archival material s and their lifetime, to explain the importance of environmental control for archives preservation. Then according to the publications of ASHRAE, the authors introduce the low -temperature and low-humidity environmental control technologies needed for preservation of color photographs and films. Basic air-conditioning principles and system design concepts are included.
