Abstract: Archaeological museums are usually constructed at the location where historical relic sites are unearthed and are often characterized by large-space building layouts and high energy consumption for the environmental control. However, the traditional strategies for environmental control are limited in protecting the unearthed relics from desiccation cracking and salt concentration. In this study, an environmental control strategy of evaporative cooling system is proposed as a solution to develop a sustainable preservation environment to maintain the condition of the ancient relics at a state of moist saturation. Afterwards, a verification of sustainability and climate suitability analysis of the proposed system were conducted. The results indicate that (1) the evaporative cooling system can fulfil the high humidity preservation environment requirements for the unearthed historical relic sites with a low energy consumption; and (2) the potential use of the evaporative cooling systems is significant in Xi’an and Chengdu (i.e., being 62% and 75%, respectively), and not in Lanzhou and Urumqi. As a conclusion, the proposed strategy provides a sustainable protocol for the preservation of unearthed historical relic sites in archaeological museum.
