Experimental Research on Independent Environment Control in Museum

抄録

The indoor thermal requirements in archaeology museum buildings mainly take into account the comfort of visitors and the preservation of the in situ relics. However, the environmental conditions for the thermal comfort of visitors are usually inconsistent with those for appropriate preservation of relics, and the specialized needs of the latter are usually ignored due to financial and technological limitations. In this paper, the recommended environmental conditions for preserving relics were revisited, and the criterion of optimal conservation of in situ relics by establishing the equilibrium of heat and mass in the air-soil coupled environment according to the primitive soil environment parameters was presented. Based on these various requirements, an independent environmental control system concluding a split air conditioning system for visitor comfort and a capillary radiant system for relic preservation was proposed. A laboratory room consisting of a funerary pit and the mentioned air conditioning systems for human comfort and relic preservation were constructed to simulate a large exhibition hall of an archaeology museum. Experimental research has been carried out to examine the feasibility and performance of the method. The results show that both of two systems could be operated independently with different working parameters and operation models. Additionally, the different environmental needs of visitors and relics were simultaneously satisfied with this energy-saving method.
