An adjustable constant humidity system for museum showcases

Abstract

The invention discloses an adjustable museum display cabinet constant humidity system. A plurality of museum display cabinets are arranged in a museum exhibition room, the constant humidity system comprises a constant humidity unit, the constant humidity unit is communicated with the museum display cabinets through an air conveying pipeline and feeds constant humidity air into the museum display cabinets in a positive pressure mode, the air conveying pipeline comprises a main pipeline and a plurality of branch pipelines, and the branch pipelines are communicated with the museum display cabinets in a one-to-one correspondence mode. Each museum display cabinet is connected with a microenvironment humidity measuring and control system, each microenvironment humidity measuring and control system comprises a valve, a humidity sensor and a microenvironment humidity measuring and control module, and the microenvironment humidity measuring and control modules and a microenvironment intelligent monitoring platform transmit information through communication modules. The adjustable museum display cabinet constant humidity system has the advantages that the defect that the moisture control amounts of all the museum display cabinets are unbalanced is overcome, the danger that control over the humidity of the rear end museum display cabinets is insufficient is eliminated, and the effect of building differentiated humidity environments in the different museum display cabinets of the same exhibition room is achieved.

Description

technical field [0001] The invention relates to the technical field of museum cultural relic protection equipment, in particular to an adjustable constant humidity system for museum showcases. Background technique [0002] The current micro-environmental humidity control in museum showcases generally adopts a centralized control method, that is, only the constant humidity unit is used to control the humidity of all museum showcases in the entire museum exhibition hall, and the constant humidity unit passes the conditioned air into the museum through pipelines In each museum showcase in the exhibition hall, the humidity control of the micro-environment of the museum showcase is realized. This method brings certain hidden dangers to the protection of cultural relics. On the one hand, it is difficult for a single constant humidity unit to meet the differentiated needs of all museum showcases in the exhibition hall. The constant humidity unit can only output a uniform humidity...

Problems solved by technology

This method brings certain hidden dangers to the protection of cultural relics.

On the one hand, it is difficult for a single constant humidity unit to meet the differentiated needs of all museum showcases in the exhibition hall

The constant humidity unit can only output a uniform humidity value, and a single humidity control value cannot meet the requirements of all cultural relics in the exhibition hall for the differentiated humidity environment of their display cabinets. Exposure to inhospitable humidity and risk of destruction

To meet the differentiated environmental requirements of different cultural relics, multiple constant humidity units are required to provide gases with different humidity, which is costly and may cause a large waste of resources

On the other hand, the existing control method is difficult to ensure that the air intake of all museum showcases in the exhibition hall is consistent

Use the pipeline to transmit the air with constant humidity to each museum showcase, so that the museum showcase at the front end of the pipeline will get a larger air volume, and the museum showcase at the back end of the pipeline will get a smaller air volume, resulting in an unbalanced air volume of the museum showcase, which will lead to some The humidity control effect of the museum showcase is poor, and the energy loss is large
