Abstract


Relic is our precious historical and cultural heritage. Providing a suitable environment to relic is one of the main functions of the museum building. Han Yang Ling underground museum is a new exploring for exhibition forms, a protection and display method of enclosing a large area by glass is used in the museum for the first time. Relics and visitors are separated in two relatively independent spaces so that visitors can multi-angle view the relics on the premise that the relics can be protected in the maximum. Currently, the researches for the method of relics conservation and presentation is incompletely, and it demands a comprehensive analysis of thermal and humidity environment. Since the bottom of protection hall is earthen sites, the heat and moisture coupled transfer, heat dispersion and evaporation directly affect the thermal and humidity environment of the space.Take Han Yang Ling museum protection hall of burial pit for example, this paper tests the thermal and humidity environment of the enclosed space, analyzes the characteristic of thermal and humidity environment in enclosed space and the condition of soil evaporation, discusses the environmental problems in protection hall, and provide a detailed data for the reseatch of the thermal and humidity coupled transfer of the semi-infinite earth under the enclosed space and thermal and humidity environment of enclosed space.In this paper, the thermal and humidity coupled transfer of semi-infinite earth in enclosed space is investigated. Based on the analysis of the principles and mathematical model of thermal and humidity coupled transfer, using the moisture content and temperature gradient as the driving potential, adaptive governing equations for the semi-infinite earth under the enclosed space are proposed, and the boundary conditions are determined. The evaporation process of soil under the closed condition is discussed, which is the foundation for the comprehensive analysis of thermal and humidity coupled transfer processes of the semi-infinite earth and its thermal and humidity environment in the enclosed space. This paper discusses the relationship of the thermal and humidity coupled transfer and the thermal and humidity environment, investigates the ineraction between air relative humidity and soil evaporation rate, analyzes the soil evaporation process according to the test data of Han Yang Ling protection hall, and makes a proposal for the solution of dry soil crack.This paper studies influence of thermal and humidity coupled transfer to thermal and humidity environment, discusses the features and main impact factors of Han Yang Ling museum protection hall, proposes a dynamic models of appropriate protection of the protection hall including the inner surface heat balance equation, the indoor air heat balance equation, and indoor air humidity balance equation, and using stable thermal and humidity process theory calculates the wall heat flux, soil evaporation rate and condensation rate of the protection hall, analyzes thermal and humidity process in the Han Yang Ling protection hall, explaines the causes of existing environmental problems. Then this paper discusses the influences of envelope forms of enclosed space, height of enclosed space, soil moisture absorption and desorption to thermal and humidity environment, indentities that heavy envelope and large space have good thermal and humidity stable performance.
