Abstract

The invention provides a precious object low-temperature preservation system. The precious object low-temperature preservation system comprises an airtight space, and a refrigeration system consisting of a condenser, a refrigeration compressor, an evaporator and an air blowing component, wherein air return channels communicated with each other are respectively formed in the side walls and the bottom of the airtight space; an air inlet is formed in the air return channel in the bottom; an air flow stabilizing layer is arranged at the top of the airtight space; the evaporator is mounted at the top of the airtight space, and is communicated with the airtight space; and the condenser and the refrigeration compressor are mounted out of the airtight space. The precious object low-temperature preservation system can acquire temperature parameters in the airtight space in real time, and adjusts the temperature in the airtight space through the refrigeration system. Meanwhile, the special structure of the airtight space guarantees the control precision and uniformity of the temperature in the space, realizes intelligent temperature control, satisfies the preservation environmental requirements of precious objects, and accords with the requirements of product simpleness, stability and reliability of users.

Description

technical field [0001] The invention relates to a low-temperature system, in particular to a low-temperature preservation system suitable for precious items in an airtight space. Background technique [0002] The combined effects of temperature, humidity, air pollutants, and harmful microorganisms accelerate the aging speed and damage of precious items such as cultural relics and artworks, and shorten the preservation life of precious items. Sealing and constant temperature storage of precious items is an effective way to reduce the fluctuation of ambient temperature and humidity, block the intrusion of harmful gases, and prolong the storage life of precious items. [0003] In the prior art, large-scale air-conditioning systems are mostly used to control the temperature and humidity of multiple spaces at the same time, and some small spaces are independently controlled by air-conditioning systems. However, the temperature control accuracy and uniformity in this type of desi...
